I searched your forum but could not find the same issue posted, so I am hoping (based on my description)you have seen this issue before and can provide a fix.
I have the UGA-2K-A w/the Displaylink DL-195 chip. It works on my previous system, but not on the new one. The new system is as follows:
HP Pavilion P7-1410
Geforce 9800GT w/1GB VRAM(Driver Date 1-18-13)
The current behavior is that the device will not display anything. The system sees the device and it appears to be installed correctly. However, the device will not always recognize the connected display. Sometimes it will say ‘No Monitor Connected’, other times it will correctly identify the Flat Screen. Even when it does, when I click on ‘Identify’ in Windows Display Properties, nothing is displayed on the screen.
It does seem to be a system specific issue, because the device does work on other Windows 8 computers and I have tested other DisplayLink adapters on this computer and get the same results. I’m just hoping that I am not the first with the issue and you have an answer. Even if it is “Sorry, there is no fix”.
I have tested the device by installing the first Windows 8 compatible driver and then updating it to the latest. However, when I tried to install the April 3rd driver, it said the driver was already up to date. So I uninstalled the current driver and reinstalled the April driver manually.
Please let me know if you need any further details.
