Hello.

Recently I’ve upgraded my GPU but since my BenQ XL2411 only has a DVI port and it’s HDMI port does not support more than 60HZ, I had to get this adapter to be able to utilize my 144HZ.

Everything works as expected for the most time as well, but sometimes there are some weird issues.

First of all, even though my DVI cable is plugged into the adapter and screwed in tightly, small movement makes a few RGB pixels appear jumping randomly over the screen. Not extreme, you barely even notice them – but this definitely is issue number one. Moving the cable around a bit (even though it really doesnt move) makes them disappear at some point.

Then issue number two comes into play, sometimes completely out of nowhere the monitor just goes black.. like it turns into standby. Then it turns on again, takes a while to jump into 144HZ mode and MAYBE it then actually goes to a picture, or maybe it doesnt, repeating the on-off cycle indefinitely.

Unplugging and re-plugging any cable usually fixes the issue.

Is this a known problem or did I somehow get a faulty adapter? This also does not seem to be related to powerspikes or similar since I’ve been having this issue on the plain desktop quite often while sometimes when playing something like Cyberpunk2077 nothing happens at all. Most likely some of my cables move some of the adapters cables when using my headset or mouse, and this leads to the issues happening since there is a loose-contact situation going on or something?

Any input would be appreciated!
