I have a Dell Precision 5570 laptop which only has usb c ports, so in order for me to have hdmi ports and usb a ports, I connected your adapter "Mokin 6 IN 1 Docking Station USB C to Dual HDMI Adapter" SKU: MOUC0412

This is the sequence when only the wavy pixels issue happens:
[normal screen] [instant wavy pixels somewhere on the screen] [normal screen]
This is the sequence when it happens together:
[normal screen] [instant wavy pixels somewhere on the screen] [instant black screen] [normal screen]
To reproduce the behavior:
1. Connect a physical monitor (I used dell physical monitor and others) to the mokin hdmi ports (I tried both).
2. Use it for few hours.
Expected behavior:
Being able to use the physical monitor for few hours without any random instant GFX issues (wavy pixels) which occasionally followed by instant black screen interruptions.
Actual behavior:
Random instant GFX issues (wavy pixels) which occasionally followed by instant black screen starts appearing after some time (could be after minutes or hours) where it works fine until that point. It could happen again randomly after some time (could be minutes or hours). Note that I had sessions where the issue could get so severe it would be happening like every 15-30seconds (which is not that random anymore).
Things I've tried to resolve the issue:
- Switch hdmi cables.
- Ensure my windows 11 updates are up to date.
- Made sure target machine advanced display settings it shows 1080p at 50 hz resolution.
-Used different display monitors.
-Update my video card drivers to the latest.
Screenshots/Videos
This is what the gfx issue (wavy pixels) look like (note how towards the end of the video a large portion of the pixels are "melting" and going out of order):
Wavy pixels:
Note that it's happening in different areas in different programs, windows, etc.
It causes some letters sentences to tilt like a wave in some area / lines of the screen.
And this is the regular display how it should be:
Black screen blinking in and out:
Additional context:
If I'm using the adapter "Dell DA20 USB Type-C to HDMI/USB", I'm not seeing these issues happen, so this could indicate there is some issue with the MOKiN adapter.
Are there some drivers or fixes to these reported issues?
Thanks.
P.S.
It looks like other customers reported the same issue, "pixelated" is what I call "wavy pixels" and "blinking" is what I call "black screen" (if you search for these terms in the reviews search):
