I use an HP Compaq 8100 system with a triple monitor set-up, 2 monitors from a dual head nVidia geForce 310 and a third monitor connected on UGA-2K-A.
A couple of days ago, I restarted the system after an displayed error related to no support for OpenGL 1+ (I think it was about OpenGL) on my third monitor (USB-DVI).
After I restarted the system, the second monitor connected to the geforce was not detected any longer. I uninstalled the DisplayLink driver and support software (with a restart) and then nVidia software, re-installed the nVidia software without being able to make the software to recognize the second monitor. Finally, I changed the nVidia video card and that solved the problem.
This morning I decided to give another try to the UGA-2K-A adapter and I downloaded and installed the latest software from DisplayLink. After the installation, the first and second monitor (geForce) started to cycle through a loop of video changes that included a temporary black out of the second monitor. When I identified the monitors, the USB connected monitor was identified as the second monitor and the former second monitor as the third monitor. After a system restart, the second monitor connected to the geForce was not detected any longer.
Now I have a system with 2 monitors working using two dual head nVidia geForce 310 cards that cannot detect the second monitor.
Based on my experience, and loss, I cannot recommend the usage of UGA-2K-A under any circumstances. Please advise! I don’t think that there is a an emoticon to descibe what I feel.
