No image visible

[bugmenot]

Hello,

I just bought the USB 2.0 Display Adapter (WS-UG19D1), revB and wanted to install the adapter in order to use another monitor.
Sadly this isn't working. After installing sw version 7.21 I connected the monitor via HDMI.
All I'm getting is a black screen. Windows recognizes the display and also shows the resolution that I set in the tray but there's no image. Sometimes blue and white patterns are visible but that's noting like a desktop...

Can you help me with this issue?
Is my device broken?

Laptop: Acer 5943G, AMD 5850 Mobility Graphics Card.

Best regards

Hey,

thanks for answering!

I just installed the newest Catalast (13.4) and ran your support tool. The zip file is attached.

From what I've tried yesterday I can say the following to narrow down the problem:

When I boot the PC and everything starts for the first time I can see the image on the left side This is a cool thing! Looks really nice having a third monitor. BUT: The longer everything operates the poorer everything getts. First I start seeing artefacts and pixel errors after that the hole image is getting distorted and after that the image is gone. The image is then just black, white and yellow artefacts... after that the image is totally gone and I can't do anything to get the image back again.

I really hope that the zip file is gonna help solving this issue.
I'd really like to use the device for the third screen (1280x720) (just for office purposes). I hope this is possible.

Thanks!

One other thing:

Since the monitor is a TV it suffers from HDMI overscan... I can't change this in the settings of the monitor If i unplug my lcd monitor (the one that is connected via native hdmi) i can use fit to screen and thus solve this issue. The problem however is, that once I plug it in again everything is back to normal
I'd need a resolution of 1220x670 due to overscan. Is it possible to unlock fit to tv when I have the other monitor connected? What does this lcd have to do with the displaylink adapter?

Edit:

The issues got way better since I'm using a VGA-Cable.

1) The overscan is gone since now I use the PC-mode of the screen which disabled overscan

2) The image is a lot more stable. It looks crystal clear in the beginning, however after 5 mins (and not 15sec as before) I start getting artefacts, which keep ketting worse and worse. Unplugging the cable and inserting it right after doesn't help. I need to wait at least some minutes until I can repeat the process.

Any Ideas?

Any news concerning the artefacts and image losings?

Come on, guys... What kind of support is this???
It's been weeks since I've uploaded the log files and I did not even get a "we're looking into this - nothing!!".

I'm afraid, if I have to wait much longer I'm gonna return the device and say bye bye to displaylink...

I'm not complain about support any more... It's a shame... Well anyway, if somebody is going to help me...

I tried the 8.1 preview drivers and they are behaving far worse than the 7.21 with mouse freezing fix.
7.21 mouse freezing gives me 5 minutes without distortions, 8.1 about 15 seconds...
Does that help?

Thanks

Hi,

Sorry for the delay in replying.

This sounds like an electrical fault with the adapter.

Do you get this issue with the other monitor in your setup?

If so please arrange for a replacement.

Thanks,
James

Hello and THANK YOU for replying!
So it seems that the log-files were okay after all?

Well, same thing happens with the other 27" monitor... Distortions after some minutes with 7.21 freezing fix.
But how can it be, that the old drivers can give me a clear image like 10 times longer? Doesn't that sound like a software-related issue?
