4.6 (Samsung): Impossible to play video, games stutter after trying to - any ideas?

Gamer · 10-20-2009, 02:02 PM

Here are some screenshots:

As you can see, the 3 extra monitors are only visible in the device manager and allegedly connected to my main video card.

During the long hours trying to get rid off this driver, I already once tried to remove the monitors from device manager. Result: Reboot required, after that: GTX 260 is not accessible anymore (VGAsafe driver). Impossible to install a driver for it, impossible to uninstall the old one (even in safe mode!). That's why I used system restore in hope everything would be gone!

But it is not - I still have the same symptoms when trying to play video as I had with the driver "really" installed!

If you say the driver is gone according to registry, then it must have left something severely messed up. Something that also affects the Nvidia card drivers.

Hello,

I cannot see anything that should cause an issue now. I would suggest you reninstall the nVidia graphics drivers.

I'm sorry your problem is quite severe, but with everything related to displayLink removed, there is little else I can do.

Best of luck,
Martin.

Ok, to my surprise, that simple step did it. The leftover 3 monitors are still there, but I can finally stop watching videos in a VM after 1 week.

However, this also proves in my opinion that the DisplayLink software fiddles around with the main graphics drivers - and may break them in a strange way.

Just out of curiousity: In what way is your driver interacting with the main graphics hardware? I mean actually there shouldn't be a reason? Back in the old days, I used an additional PCI card to have a second display. The drivers acted totally independent from one another. I thought the same should apply to DisplayLink hardware, which is "a virtual graphics card on a chip behind the display"? And why this additional entry for the monitor under "Programs", but not in device manager, where it puts even three monitors of which you then see only one in display properties? It all seems a bit weird to me, but maybe I can get the logic behind if it is explained to me...

Thanks for now, back to watching videos...

Hi Gamer,

We do indeed install a virtual graphics adapter, and under XP you will see this as "DisplayLink Graphics Adapter" in the "Graphics adapters" section of Device Manager. We do not "take over" the native graphics adaper on XP, but there can sometimes be interoperability issues with native drivers that do not expect to be installed along side other drivers. This is rare and more commonly small applications like CCC or the intel graphics properties applications have problems with multiple drivers. This is something that is very difficult for us to address.

The "Samsung Ubisync Monitor" in Add/Remove Programs is there because you installed the 4.6 version from the samsung cd. This is absolutely as designed. The customer is not expected to know that to uninstall their Samsung Ubisync monitor they should unstall "DisplayLink Core Software", as they may well have no idea who or what DisplayLink is. You will have been affected due to your experience and participation on the beta program where software is branded as "DisplayLink Graphics". There is a request to remove the "DisplayLink Core Software" entry, but there are both positives and negatives to this.

Unfortunately I have no idea why there are several monitors listed in Device Manager, but as far as I can tell, it will have no adverse affect on your system.

Best Regards,
Martin

Thanks for the information!

Since you've really tried your best to resolve my problems (even though I was quite mad and had already returned the unit a week ago), I now have gained some confidence in DisplayLink, so maybe next year I will try your technology again with another device.
