I have a USB-VGA-165 and it is not looking too good. Every movement of the mouse across the screen makes the screen flicker and go in and out of focus. It is running at 1920x1080… I also have an AOC 21" USB monitor attached, which I think uses the same DL-165 chip, and is also running at 1920x1080 - it looks rock solid. Detaching the AOC does nothing to improve the look of the monitor on the USB-VGA-165
EDIT: Did some trouble-shooting: Attached it to a different computer - same issue. Swapped the USB cable - same issue.Tried the monitor with straight VGA connection, and the monitor is fine… so I have isolated the issue to the USB-VGA-165 box.
