Hi there,
It seems that the driver can wake up the display from sleep a finite number of times (I think 2?).. before having to reboot.. removing the USB cable and replugging it doesn't help. Even if I change the resolution, the screen will flicker but nothing comes on.
My eVGA device is used as a reading device at 90Degrees rotation. It just doesn't wake up after sleep (even unplugging and replugging the device USB).. unless I restart the machine.. which is a pain in the butt. Is there a logging feature that we can enable?
The console doesn't give a whole lot of information when on the status of the driver.. but I think the area below gives some clue to my situation:
