Error Code: 304. The GPU failed to perform image processing

I get the following error after I choose project:
"The GPU failed to perform image processing because of an error. Error Code: 304."
This error completely shuts down Davinci Resolve and I cannot open any project.
Still the same after restarting computer and updateing software.
My GPU seems to be fine. I tested it on som GPU intense game.

How to get rid of this error?

This is strange. I have USB Monitor connected to laptop. It looks like it causing problem.
How is it possible?
Can I report it somewhere?

PLEASE HELP! Losing my mind here!!! I'm on RHEL (Fedora) the only way my application (DR) works here is when I select openCL in memory and GPU preferences. Then I don't get the GPU error out of Memory error box BUT now the trade off is that my media pool doesn't show any image as well on the timeline. Where as before, when CUDA is selected in preferences, the images show but when played on the timeline, the image shows as an abberation of colors and stutters then crashes. WHY??

Thanks @uclauc. I had a monitor connected via a usb3 hub. I went direct via hdmi and the problem went away.
