Default Windows 10 Anniversary OpenGL Drivers Ancient

The recent Windows 10 Anniversary update has removed the DisplayLink driver and replaced it with the new driver. Everything works okay except for apps that require at least OpenGL version 2.1 because the new Windows driver only supports OpenGL 1.0.

Is there a way to update OpenGL for the DisplayLink hardware to OpenGL 2.1 or higher? 4.3 would be nice!

Hello,

We have noticed an issue with graphics card capability enumeration. DisplayLink does not compute so we don't do the OpenGL, the primary graphics card does the work.

Do you have a multi graphics card machine? Something like Intel + nVidia for instance.
If so, can you try and disable the Intel card?

Having your logs (described in my forum signature) along with the name of the application you are using would be helpful. I'd like to see if this will be addressed with the next Windows release.

Kind regards,
Alban

Hi,
The app that has an issue is a 3D Printer app called XYZWare from this company http://www.xyzprinting.com/

The second app that has an issue is a Web App from Onshape.com.

The XYZ app works fine on the primary display but will not work correctly (image quality is degraded) on the DisplayLink monitors. XYZWare shows an error message that OpenGL2.1 is required.

The Onshape.com web app crashes with a WebGL error. Both of these apps worked fine on the DisplayLink monitors before the latest update. Onshape is now crashing on the primary monitor which runs opengl 4.3

Thank you, I wrote to XYZ. I haven't seen the logs or answer to the questions so we'll see what we can do without...
Before the Windows 10 v1607, the operating system and graphics were different. However in all cases, the pixels are always computed by the primary graphics card regardless of where the monitor was and is now connected.

Kind regards,
Alban

Hi Alban, WebGL crashes with the latest update. Here's the GPU status reported by the Chrome browser if that helps. I don't know if this is directly attributable to DisplayLink or not - it's very hard to say but since the Windows 10 update, things have really impacted me negatively. I rely heavily on my dual monitor setup with DisplayLink.

Hello Deon,

I'm delighted to report I received a reply from XYZ Printing very quickly.

Would you please be able to run our customer support tool and post the resulting ZIP file?
My signature explains how to provide this, and the file posted here can only be downloaded by employees.
Having this will give the machine details to find ideas and identify the closest machine we have.

Could you also save the output of the Chrome GPU diag as a PDF and attach? You can do this by pasting chrome://gpu in the omnibox.

Kind regards,
Alban

Hi Alban, any thoughts? There is a definite problem with all OpenGL apps. Onshape.com for example is virtually unusable on the Displaylink monitors. On the primary laptop screen, things work in real-time when the display link hub is disconnected.

Hi Deon,

I was trying to get the software from them to get a repro for debugging. After providing me with a link which doesn't work as it's a login wall, a "technical manager" told me to get lost: I'm so not only supposed to magically have the software but I'm also expected to already know how to use it to create a 3D model.
I'm highly unimpressed.

Regards,
Alban

Hi Alban, customer support has never been very good over there! However, I ran into another app that is freely downloadable that has a very similar problem. Designspark PCB. Whenever you try to display a 3D image of the circuit board on a DisplayLink monitor, the system bogs down completely. You can download the software from here: https://www.rs-online.com/designspar...rical-software

Registration is free as is use of the software. When you open the software, a default circuit board is loaded. Click on the .PCB tab and then choose 3D from the menu. The 3D view will eventually display but interaction with it is painfully slow. Rotate or pan the model to see what I mean. This software definitely used to work in realtime before this latest driver update.
Software works fine on a non-displaylink monitor. Since all my work is 3D related, and it all used to work just fine on my displaylink monitors, it is definitely related to the driver update. I now have to do everything on my laptop screen. This is the only way to work in realtime!

Regards
Deon
