Animated / Moving content stall / freeze

[OpenFasciata]

Hi,

I've got a lilliput UM-70 USB monitor.
Tried many things, but come to the conclusion that it's likely to be a displaylink driver problem. (although influenced by external apps i.e. windows updates/perhaps usb sticks usage)

Hey I have exactly the same issue / problem with my um-70

When I bought it, it never showed anything moving (video - youtube - flash - winamp - ..)
But when I did place window over it (while dragging around - holding with mouse),
then it did show the video.
So I always knew the display is capable of displaying video, nevertheless there is some sort of refreshing - layer - priority problem.

Nothing solved the issue.

I now made a fresh install of windows 7 64bit (same as before) and it worked!
For 2 days.... however.

No today I have the same problem again, I didn't (intentionally) change any configuration or installation as far as I know.
So I expect some kind of driver - windows update might have killed it.

I experience this problem with every moving video type content.
Youtube and Winamp.

If it is lack of resources, there is no hardware difference in USB devices since yesterday.
But I did tried a USB stick yesterday now I think of it.
And that stick didn't function,...
I have to digg into this.

So yes there might be some windows registration issue or so?

What settings do we need on windows registry? (what does influence the device?)
Or any other suggetsions? The total capacity of USB devices isn't really logic, since these didn't change and it worked before. And at my last installation it never worked (unless like described with floating windows over it or with the mouse over parts).

Any advice - help is welcome.

I do not use aero at all.
I use optimized setting for performance.
Windows classic + solid black as background.

hardware:
i7 920 12gb
asrock x58 deluxe
nvidia gtx275

Since I had it working for a small period of time when I freshly installed windows 7 64bit,
I suspect that usb stick screwed a setting over (maybe in windows registry?)
Or else an windows update killes the priorities or such (layers - windows priorities).


When I use winamp video stream, I drga the window from main monitor to lilliput um-70,
the video stalls at current frame.
When I drag back to main monitor, it simply plays as should.
image example when I drag an other window half over the video player screen, then the video starts playing. But as soon as I drag the other (explorer in this case) window away, so it's no longer on top of the video, it stops playing.

Printscreen looks like this, when other window is dragged over the video, it plays.

When I now drag over an firefox window, with the lilliput review video on it.
(for reference
youtube video: Jx6G2k1R6Hg
And maximize this window to full screen, while the winamp video stream is still playing (yet still stalling), then you get the idea,.. (see next printscreen)

[[ for the image see original mp3car forum, can't post images here ]]

As you see everythign gets scrambled, all sorts of window-layers, which are stalling.
At the bottom the firefox window is still not maximized, and you see the winamp bar on the right.
while on top, firefox is maximized, but inside firefox, winamp video is prioritized and shows above the website content, while the video on youtube (blue) itself is prioritized over the winamp videostream.

Now if I drag the firefox - youtube window back to the other monitor, this is what is left behind:
(the video should still play, but is stalled - and youtube video is still over the winamp video stream window)

[[ for the image see original mp3car forum, can't post images here ]]

My conclusion so far:
some content get prioritized above others (layers - windows);
some content doesn't get refreshed, based on this priority "setting";
the usb is capable of showing the content, else it wouldn't show smoothly when dragging an other window half over it, also when the problem didn't occur, it does work fluently.
It's not hardware, but software related.

A setting somewhere messes up the prioritizing of the content.

(in my case it looks like driver updates - windows registry might be involved)

removing + reinstalling the display doesn't seem to work, so might be windows realated (registry - windows updates), or some setting somewhere which gets left behind after completely removing the monitor by uninstalling and removing from windows devices list..

I hope the developers gets this info, because this should be enough to point them into the right diretcion.

I hope this gets sorted.

I 've tried a.o.:
*] installing - reinstalling nvidia drivers

*] installing - reinstalling DisplayLink USB Graphics Windows Driver 5.6 M1
Release Date: 18 April 2011

*] removing the windows registry record of usb devices
wikihow com Clear-the-Record-of-USB-Plug-in-Equipment

*] Reinstallation of windows 64 solved the problem temporarily,
but then after a few windows updates (and usage of usb stick?) the monitor no longer works..
Same before on windows (although never used any usb stick by then - so might be coincidental - just try to remember and guess anything related)

My conclusion so far is as stated before:
a priority - addressing issue with the layers - windows. (video content is usaually forced to front - top -- while it does seem to work when somthing else is partially dragged over it -- but stalls again when the window above it is stopped dragging - released - moved)
