Windows 8.1 and Lilliput 7" issues

armaldon · 10-22-2013, 01:27 AM

I have still have not found a solution. However, I have found that this problem only happens when the USB monitor is set to "Extend Desktop" (even as the main monitor), if I have it set to mirror any of the other screens, the display behaves normally.

Stoney is using an NVIDIA GTX 670 discreet graphics card and I think it might be something specifically to do with this graphics card driver causing the issue.

armaldon - can you confirm what your system details are, especially the graphics card to confirm this is the same issue?

I also do have the same graphics card, Nvidia GTX 670. While on Windows 8, it work fine with the 327.23 driver. After installing Windows 8.1, with the same driver, the monitor problem started. I have updated to the latest driver released yesterday, and the problem still persists.

I also updated to the newest NVIDIA driver yesterday, problem still remains.

A few other observations that might help.

I primarly use the USB monitor to display Rainmeter. When the program settings is on focus, it displays on the monitor, when it loses, the screen becomes dark. While on focus, if I right click on the monitor, nothing happens. Left clicked on it, brings the start screen.

Putting Chrome in that screen, it behaves correctly while it is on focus. When it loses focus, the screen goes dark again.

With the windows explorer windows, they won't show, even if they are on focus.

Thanks for the update. We're buying this card to try and reproduce the problem and fix it.

I have a Dell Latitude E6530 with Nvidia NVS 5200M & Intel HD Graphics 4000, and my computer monitor now blinks randomly.

I am experiencing the exact situation as Post #12. I have Rainmeter on my 7" USB display, and is worked correctly under Windows 8. When I upgraded to Windows 8.1, the screen simply displays my start screen color and will show the start menu if I click on that solid color. Moving windows to that screen will show them until I click on any other window.

I have a Intel DH61CR motherboard and Core i3 processor, two 17" screens using the built-in Intel Graphics, with a third 7" DisplayLink USB screen

OK - we have an NVIDIA 670 GTX and reproduced the issue. Now being investigated.

The issue we reproduced looks to be something different to the problem on this thread, as it was caused by multiple GPUs on the test machine (an unsupported scenario).

Now we have the GTX 670 as the only graphics card, it is working fine. Suspicion is that this could be something to do with Windows as it sounds like we are rendering the pixels that Windows gives us onto the USB display.

Could someone record a quick video to show what they are seeing? Also, when you see the problem, can you "print screen" and paste it into Paint, and see if this is the same as you are seeing on the extended screen? If so, then this sounds like a Windows issue with multiple displays and Windows not correctly rendering the desktop to all displays.
