cmwade77: Just to clarify, are you saying that the 'J5Create' driver works with the DisplayLink adaptor or are you meaning get both the adaptor and driver from J5C? Can you send a link to their facebook download.

Come what may, I might have to consider ditching DisplayLink. The lack of support has been pitiful. All communication appears to have stopped.

No, I am saying that the J5create device works and you may wish to purchase one of those devices instead.

The manufacturer of my device (Pluggable) is considering switching to the chips that they use (I believe it was MTA or something like that) as a result of this in the future. I have to say that their support has been excellent, but has been limited by DisplayLink's lack of support on this matter.

Hi All

I have updated the status of our Mac development here:

http://displaylink.org/forum/showthread.php?t=2007

Wim

All of the issues listed there only happen when the login screen does not appear. Another issue is that Flash crashes when the login screen does not appear.

If you fix the login screen not appearing, all other issues should fix themselves as well.

Could we possibly get a beta of the 1.8.1 to test out with? We use these for business, luckily the manufacturer of our device has been very kind and offered us refunds, but I would still like to have them working properly instead, as I like their company better than the competition that already has drivers that work properly out.

Will the update fix generally lag in window events? How about a weird screen glitch that causes a double of my cursor to appear?

Thanks

I'm looking at what we can do to release a beta, with minimal impact on the engineering team.

Once we have the architecture, we hope it will fix all the weird issues users are seeing. I'm sure there will be new problems with the first beta releases of 2.0 we do, but the new architecture and code base should make it much easier to find solutions and fixes.

Wim

While I look forward to 2.0, I would just like to see 1.8.1 now. You do need to keep up with your competition, who already have drivers that are fully compatible with Mountain Lion and work with USB 3.0 devices.

I like you chips a bit better, as they seem to run faster when they work and I like the manufacturer that we are dealing with that uses your chips, so I want this to work, but it is going to need to do so soon.

I appreciate the information update, however the problem that I see is the sheer amount of time that has elapsed since Mountain Lion shipped. Even that has now progressed to 10.8.2 and could easily jump up again before a Display Link Beta.

I also think that it is totally wrong not to mention this to unsuspecting new users of the Display Link driver, (that it is NOT compatible with Mountain Lion). Your download page suggests that it is Mountain Lion suitable, when clearly this is not the case.

I implore to speed up the process and remove the broken driver from your download page.

At bare minimum, make a note that the current driver is NOT fully compatible with Mountain Lion.

1.8 drivers don't work with osx 10.8.2
 

I am running a business and bought 12 of these to use with our macs. This is complete unacceptable. Just like what everyone else is saying once i install the drivers everything else starts crashing. This needs to be fixed now. I have invested over $500 in this hard ware, and I am not about to have to pay for restocking fee. Please fix this problem or send me a check for the full amount of the product. I believe that I wouldn't be the only one ready to seek legal action against your company. Please just simply fix your product so we can use it like it is advertised to work. Thank you

I would say this is poor policy. I have had to reboot my system so many times it caused damage to the file system, and I have had to do a full restore. Glad OS X has Time machine.

I have a quad monitor set-up at work and quad at home. I have had no problems to date, but with the DL driver loaded I have had so much instability, besides the Blank login screen, and core dumps, I have had MS Office 2011 inability to start and crash. Cold start, same problem, Word, Excel, Powerpoint, crash. Uninstall the driver, cold start, MS apps AOK.

3 adapters per location, but these were purchased a while ago. I rely on this to work to be productive. Sorry if MAC users seem impatient, but we put up with Apples crap, underpowered hardware, RAM compared to the PC market, because "A Mac just works", and that is what you want when you need to be productive. This driver destabilizes the OS, and REMOVING it is NOT an option! Now a 2.0? manes me really want to consider upgrading and replacing my USB adapters, especially if the other forums and support area is relatively clean and their drivers work... :confused:

Need Drivers for Fixes
 

While working for a computer manufacturer I appreciate your developer team trying to improve the product in to the future.

Unfortunately that is just what I would expect from a developer.

"Yeah ... it does not work ... but we can make it better. Why don't we just rewrite the code ... and ...and"

I have heard it before. That is usually when I step in and have them forget they are a developer and put themselves in the customers place. We have a LARGE number of users that have 22-25" Displays staring back at us with a blank screen.

While I welcome the 2.0 improvements, how about they just fix the code to have a WORKING version first.

Can you imagine what you are telling us????

OCTOBER - 15, just wait until Q1 and we will fix it. That is is a minimum of 4 to 5 months you are asking us to stare at a blank screen. Do you really think that all of us will do that?

Now you are also asking your partners to argue with until now happy customers who have a $100 piece of @#$&(*&@# lying on their desk and unable to do anything about it.

Please pass our feelings to the executives (CTO, CIO, Executive in charge of Trash removal) and have them put this ship back on track by providing a fix that us with Mountain Lion 1.8.2 can stabilize on.

If you provide a fix for 1.8.2 I would be glad to Freeze the system until Q1 and not update the root kernel waiting for the full release.

I don't think there is a 1.8.1. This driver is causing massive disruption.
 

I have a quad monitor set-up at work and quad at home and work. That is 6 total. This is just rock bottom poor support. I realize how difficult it is in the US to get highly skilled IT workers. I suspect this problem goes much deeper. Remember that the ROI is low. Existing customers don't bring in additional revenue. The motivation to resolve this would be higher if this was a Win7 problem just on volume alone. What I do find unethical is that they are still claiming 10.8 compliant and selling to new unsuspecting customers. That may induce me to write my friends at @techcrunch, and @mashable, @maccult on twitter, and let them get the word out.


I am loyal, but it can only go so far. Having worked as an EE, PE working my way up after 25+ years to Director and Managing Director, I am linkedIn to some peers over at ATEN corp among many other OEM's. (ATEN are the makers of the I/O gear products, which I have 6 of, and each of my IT staff have at least one to support their second monitor. I conveyed the concern. Unfortunately they do not write drivers for their products, understand the issue, but their hands are tied. I MUST have a solution NOW. I need 30-35 units ASAP that work on Mac OS X 10.8 mountain lion. I saw that it was mentioned that a competitor has Mountain Lion drivers that work fine on their product. I don't expect DisplayLink to allow the name of a superior competitor product, and there are at least 10-12 out there from Diamond Media, to Sabant and everything in between, so it is pretty hard to tell which is the known working product.

The person that mentioned he saw a compeditors unit working with 10.8 mountain lion, would you mind sending me an email at defilm at defilm.me so I can stop our bleeding please? Clearly DL don't have a 1.8.1 that resolves the problems, or they would release a beta. I am intimately familiar with proper regression testing, but when the "city of houses is burning to the ground, you get water on it ASAP", you don't play with the fire nozzle on the end of the hose! I don't care if the units are $200 each, the productivity loss is costing far more.

Many thanks!!

PS. I will order one unit overnight. If it works, I will order the remaining balance of 30+ units that I need. I will contact you back for shipping information and I will purchase up to two units for the first provider of the working vendor information and have them drop shipped to you at no cost to you to show my appreciation.

I agree with you all... if I was in your position I would also be frustrated.

We have a 1.8.1 beta, but it doesn't address many of the issues that have been raised about Mountain Lion. If I released it, I would give it a few hours before it was ripped apart as not a solution. And it needs bug changes to 1.8 to work around the OS bugs causing the issues.

We have to get our v2.0 software out. We're whipping the dev team as hard as we can to get this done, but they're already rowing as fast as they can.

V2.0 development is going better than expected and we should be able to deliver a preview before the end of the year. But it is not ready yet, so can't just magic something up.

Wim

Even though they were purchased a while ago, I would suggest contacting the manufacturer of the device, they may have an option, our said that they are looking at using the same chips as in the J5Create's devices, as they seem to have better support and that they would replace our devices with the ones with the new chips, in the meanwhile they gave us a complete refund and let us keep the device. I honestly want to keep using their products just because of that, but I can't if they continue to use DisplayLink and they don't come out with updated drivers.

Well, then stop ALL work on 2.0 and get 1.8.1 stable and out, bottom line is your competitors have caught up and passed you. They are offering Mac support for USB 3.0 devices, even on Mountain Lion. Are their drivers perfect? No (if anyone claims a driver or piece of software is perfect and cannot be improved, I would worry about them), but they work and don't cause all of these crashes.

So, unfortunately, from our (the customers) point of view, it shows that you are not trying hard enough to get a fix out. I know that may sound harsh, but it's the honest truth.

I think it may be time to start a Twitter/Facebook campaign to warn everyone about the lack of Mountain Lion support for Displaylink devices, so that they aren't suckered into thinking that they will work.

I couldn't care less whether you call it a 1.8.x or 2.x release. I just want to be able to use my 3rd screen again. If you don't come up with a solution soon I will never find out what magic unicorn things v2.0 will do, as the displaylink adapter long will have been chucked by then.
Apart from the fact of this somewhat ridiculous support, I think your problem also is, that your user base consists of a fair share of developers and we all know how to not approach upgrade issues; mountain lion has been released for developers months and months ago and you've had plenty of time to release a working driver. Take off the note on your driver page at least, that its supposed to be working on 10.8.
Last but not least, the statement, that you're "whipping the dev team as hard as you can" gave me shivers; I'm glad I don't work for displaylink.
Don't get me wrong: I am a development shop owner myself and know how devestating Environment changes can be to resource planning, but I don't understand why management doesn't have the guts to take responsibility and officially address this issue.

Some really good points here, thank you r8r.
Yes there has been a lapse in communication, nobody could ever deny that. We should in hindsight also have tested more use cases on more platforms as the changes in the undocumented and unsupported parts of the OS we interface to (you are a developer: try to find the graphics DDK for OS X) have been much more than what seemed at first sight.

On the other hand, if a software is resulting in an atrocious user experience with version 10.8.0 of the OS and exactly the same software has a much better user experience with 10.8.2 (5 critical OS bugs fixed up to now, 6 to go), how shall we define its quality? On my system I have only 1 issue left for example and I know it's another OS bug.
You also have to consider that the same exact issues are also reproducible (on the same systems) even with the other Miracle Devices often mentioned on the forum.
I think I'll write a separate post about the whole ML user experience.

Anyway, I wanted to reassure you about the work conditions in DisplayLink.
The dev team is fine, thanks, we are actually pretty excited about progress on the unicorn.
Our version of whipping has been a very successful week-end in the mountains to bond the team with a lot of physical exercise, laughter and good cooking. Unconfirmed reports say that alcohol played a role as well..
We have open positions by the way: http://www.displaylink.com/careers/job_board.php

Cheers,
Carlo

P.S. We might change our internal code name for 2.0, I think "unicorn" is brilliant.

How about at least updating this page:

http://www.displaylink.com/support/mac_downloads.php

so that it doesn't falsely claim that you support OSX 10.8, several people have pointed out this falsehood and yet weeks later the page still says that your driver supports 10.8, which it does not in any meaningful way.

People are STILL buying the various DL based products expecting them to work correctly with OSX 10.8

Gotta agree with andynormancx about the note on the driver page.....while you guys are partying in the mountains, people are still wasting money on hardware that won't work.

Agreed. It's the least I think your company can do to at least show responsibility in addressing the problem.

Hmm....I don't think that a trip to the mountains is the best use of time until a fix for the problems is released. I definitely want my Pluggable device working properly on Mountain Lion. I don't care that it's only a 2.0 device, we have enough of these around the office that is an issue. I can see taking the trip after the fix is out, but not before.

Again, your competitors have these drivers out already (as well as ones for USB 3.0), which means they have obviously found a way around these "Operating System Bugs", so it is possible to do. Now, I do agree that Apple should fix their bugs, but if there are ways around them, then it is your responsibility to make your product work properly. I don't like the blame game, we don't accept it within our office and I don't accept it from those that I do business with. Bottom line is it either works properly or it doesn't.

I have started a Facebook page about these problems to try to bring public attention to the issue and help others not waste their time and/or money. For us, it was only wasted time as the manufacturer took care of us, but for many, it is also a waste of money.

The Facebook page is at:
https://www.facebook.com/pages/Displ...37576346278575

Not Sure Facebook is the right medium unless you get tons of people to write and link to it. I think I can have more impact writing on my Blog, and then hitting my twitter account, and asking my MAC twitter friends to populate the link so we can at least save some fellow Mac users from getting stuck in the same trap. My Blog is normally about FIber Optics, and Enterprise Network Theory and best practices, and most of my followers are Enterprise engineers, industry analysts, equity analysts in those area's. THis product does not exactly fit, but heck it is 500,000 people, and if I can get the link tweeted by all my Mac friends (You know them @cultofmac, @cali, @techcrunch, etc... we can get it in front of a million of more people in under 2 days. Heck, it only took a few days to undermine all of Egypt.... How hard could this be? :D

Another way to get the message out
 

I have some IOGEAR USB-DVI I purchased back when on Tiger 10.4! Plus several Startech, and some Kensington. They all have the Displaylink chipsets.

I added a review for my Startech units. But when I went to add one for my IOGEAR, it said "one already existed". I looked. It was a review from 10.4 and 5 stars. It had a update for Lion 10.6, Updated in December 2010 I believe, stating it works great through Tiger 10.4, Leopard 10.5, Snow Leopard 10.6, Lion 10.7. Well I updated the updated update, and note that for Mountain Lion 10.8, v1.8 is a disaster and unusable.

I noticed there are many others under every USB to DVI device on Amazon.com, and Newegg.com with 1 star. So I have reviewed all my owned devices, and that is what I love about Amazon, it notes that I am an actual purchaser.

I STRONGLY ENCOURAGE people to write reviews on Amazon.com. I fyou own the device, you can write it there. If you bought it from Amazon.com, even better.

There is a glimmering light:

Today I purchased a Mac Mini. It comes with a HDMI out and a THunderbolt port. Apple sells a HDMI to dVI cable, and of course the thunderbolt has a DVI. Native support for 2 displays with no USB 2.0 limitations. Word has it HDMI outputs coming next on Mac Book Pro's. RUmor, but Apple rumors are becoming more tangible.

I also know of a Canadian product OEM that makes many intelligent memory and laptop devices that is creating a Dual DVI from THunderbolt device. Not all that difficult to do since Thunderbolt is a dual channel technology, but takes some engineering. (Yes, being a PE & EE has it's advantages when it comes to assessing technology as I do for Wall Street every day.... Equity analysts are not all that technical.. they need technical engineers to tell them when products are sound, and which companies are leaders and aspiring, and plain poor.). Simple fact is if displaylink has 100% of it's revenues prior to OS X 10.8, and it can not support 10.8 OS X, which is some X% of category revenue, this will show up on the next income statement as a upcoming revenue reduction. Analysts need to know this information and they appreciate it.

Please post away, Facebook was the best choice for me, but I will support every effort to bring this out so that people know about the issues and will know to avoid products with these chips because of the lack of support.

Any idea of when a fix for this will be done? Perhaps something a little more concrete than "end of the year?" I really wish I would have read these forums instead of taking the driver page info for granted. I would have purchased a different product.

A success story with a weird workaround
 

I've been watching this thread for a while. Today, I took out my mimo UM-710 monitor that has been sitting in my desk drawer since I upgraded to 10.8.

My mac is running 10.8.2.

I installed the 1.8 drivers currently available on http://displaylink.com/mac.

I have two normal monitors and the mimo UM-710 monitor. They are all working right now. Here's what I did:

1\ Download/install the drivers.
2\ Reboot.
3\ Log in.
4\ Plug in the mimo monitor and turn it on. At this point, the two normal monitors flashed blue like I'd expect but the mimo didn't work.
5\ Open System Preferences > Displays.
6\ Observe that there is a dialog for the mimo monitor but there wasn't a small draggable screen in the Arrangement tab.
7\ (here's the weird workaround) I change the rotation for the mimo monitor to be 180°.
8\ Content showed up on the mimo monitor and a draggable screen showed up in the Arrangement tab. It seems to work fine.

It also worked at 90° and 270°, just not at Standard rotation. Unfortunately, I never tried the rotation setting on 10.8 so I don't know if the OS bug fixes in 10.8.2 mentioned in this thread fixed anything.

Seems like the rotation triggers some kind of software scaling/transform that works around a bug. Now my monitor is happily connected to my computer and I have an ugly usb cable sticking out of the top of the monitor. Much better than leaving it in my desk drawer and getting more frustrated with DisplayLink as a company.

I hope this works for someone else!

I also hope that DisplayLink steps up and puts a notice on their website about compatibility problems with 10.8.*. A "Known Issues" post on http://displaylink.com/mac would be a good start.

rotation
 

I experienced this same fix. Unfortunately, I can't physically rotate my monitor upside down to match the orientation. :(

I'm pleased to see that the page has now been updated to say there are problems with 10.8, well done DisplayLink.

However, the knowledge base article that they link to doesn't detail the most serious problems that I had with the driver, namely that it caused Finder and Skype to repeatedly crash and so rendered the machine unusable.

Any update from DisplayLink ?!
 

It's clear that the DisplayLink v1.8 drivers have serious problems with OS X 10.8. For instance, I am also experiencing the crash of Finder - on a brand new mac with only DisplayLink drivers installed.

Do we have any official statement from DisplayLink?
In their "Mac software releases update" post, they mention that a new version may be available on Q1 2013. Any update?

Cheers,
Luca

rotation
 

Got excited there for a moment. I set my DisplayLink monitor for upside-down orientation and restarted etc, but I still get the same epilepsy-inducing screen flashing. Oh well.

At this point I'm going to back off pushing on the DisplayLink developer because I guess it's clear that Apple introduced this bug with Mountain Lion and the developer is left holding the bag. I also use other applications in which Apple's CoreGraphics's bugs yield totally messed up visuals. I'm going to go back through this thread and see if there is a reference to an Apple bug number and then just report it myself to try and up the priority. I hear they've started seeding 10.8.3 - man I hope Apple have done something about this in that release. I wouldn't mind seeing a vague smiling emoticon from the developer as an indication that this will bring improvements.

I am not going to back off of them, the more that I use the J5Create's device, the more I realize that at least the crashing issues are NOT an OS issue, as their device is working quite well under Mountain Lion.

Yes, there are some minor display issues that are on OS issue, but these are resolved by simply moving the cursor and don't happen all that often.

After installing the driver 1.8, I randomly got the login issue after starting the computer, it doesn't show up the user login boxes.
Even though I can bypass this problem by typing my password and login blindly, I couldn't make Preview app, Flash and XCode work after that, they constantly crashed.

All programs above work fine if I (luckily and randomly) start my computer with no login issue.

Therefore, I believe that it's not just a login issue per se, but its related effects need to be resolved also.

1920 x1080 resolution missing
 

I recently went from Snow Leopard to Mountain Lion. Previously, my monitor connected via DisplayLink correctly set the maximum resolution of my display to 1920x1080. It now incorrectly sets the max resolution to 1280x1024. The highest resolution I can set the monitor to without distortion, due to the wrong aspect ratio, is 1280 x 800.

My monitor is an Acer S231HL

http://support.acer.com/acerpanam/MO...231HLsp2.shtml

As a fellow software developer, I urge you to create a tool for advanced users that would allow a person to input the maximum resolution and refresh rate manually. I know this is probably easier said then done.

Hi there,

• Mountain Lion 10.8.2
• Mid 2009 Macbook Pro 8Gb 2.53 Core2Duo
• 9400M-256MB
• VERTEX4-256GB
• 15" macbook 1440x900
• 24" plugged into mini displayport 1920x1080
• 27" plugged in usb hdmi 1920x1080

I got http://www.amazon.co.uk/Cable-Matters-Plated-Premium-Adapter/..... this today, it didn't seem to work without the driver...
so I downloaded the latest Mac driver

I saw the warning for Mountain Lion, awesome

Installed driver, rebooted, had to unplug and plug back in but it worked. Showed up in Display Prefs as the identified (with model info etc) 3rd monitor, works great with Arrangement tab, and made the usb 27" my main monitor by moving the top taskbar over

However,

• laggy performance on usb monitor (just about bareable, but really noticeable when u have two great performance monitors either side)
• sometimes mouse freezes on the screen, but I can still move it about (like taking a snapshot of just the pointer)
• also I have to sometimes make something on the designated screen happen for it to "activate" , e.g. drag a window onto it, after logging in. (As it's set as my main monitor, I cant see the login screen too) - but its a BenQ monitor that does take pretty long to start up so will confirm in more tests tomorrow
  
• but no lag on other screens
• and no crashing programs (had ubuntu VM open, chrome, skype, chrome, preview, itunes, mail)

I dunno how many days I've got till I can return it, which i will do, as i didn't buy a decent second monitor for it to lag, but I hope either Apple or the developers make it work with all the known issues, and I guess general performance, before then! You can't even get Lion in the app store, which I would do, you know, just to make use of my second monitor or something stupid, so you gotta ring apple to get a special code, great, cheers for not mentioning that on your page

Save all of us a phone call, ring one of your apple cronies and work together to update the driver before they update OSX ? how do we even know that 10.8.3 will fix it? how do YOU even know that 10.8.3 will fix it? what if apple doesnt care about your hardware? i know who does care. the people buying it.

Lag is caused by USB bandwidth limitation.. there is no way to solve it other than a hardware / port upgrade.

Mountain Lion Driver- Any news???
 

I'm still sitting here with the usb monitor adapter that I bought under the mistaken impression that it worked with mountain lion. Now that I have this $50 paperweight, I've tweeted the Displaylink twitter account multiple times and am being ignored. Anybody heard any recent updates (like within last two weeks)?

Really want this thing to work.

Hi All

We have been looking at the login issue to try and find the root cause of this. It appears that when the login issue occurs, it leads to the application crashing (finder, Adobe flash etc), so the 2 issues look related.

We have discovered it occurs when we install our kernel extension (kext), needed to add our virtual displays. To try and work out what was causing it, we tried a basic kext, using Apple example code. However the login issue can still be reproduced with this basic extension from Apple. It happens less often, but the bug is still there. We have also found it happens on other 3rd party devices. It seems there is a timing issue with adding a kext to Mountain Lion, which exposes this login issue/applications crashing.

I know you don't care whose issue this is and just want this fixed, but there is nothing further we can do to fix this issue. We are already beating on Apple's door about this bug (Bug ID# 12533718) but have not had any follow up from Apple about the cause or a fix. If there is anyone from Apple reading this - then please follow up on this issue and see how it is affecting your users with DisplayLink devices.

Hopefully together, we can pressure Apple into fixing this now we know it is an OS issue.

Thanks

Wim

Splash top
 

Hello Phillip,

I had the identical symptoms you encountered. My situation was resolved by disabling the display driver in Splash Top Streamer (a remote desktop app). I'm not sure if you or anyone else in this thread is running this app, but if you are, that will do the trick.

Cheers!
Sean

Idea
 

Is there anyway to disable the kext until the user logs in? If so wouldn't this fix the problem?
