Benq 2566k weird behavior

[kriegsnake]

Good day. The monitor was working as intended. The line is invisible on 60hz and less visible on 144-240hz , but little lines all over the monitor is there even on lowest resolution. First I thought it’s my pc, i removed gpu driver, did whatever I could, even changed the cable. When Pc boots and you see bios logo there is no problem there, as long as you jump into windows the problem persists. Even with turned off and on monitor shows the line. It happened after I booted my pc in recovery mode, maybe in other resolution and after jumping into windows i think the same wrong resolution kept inside of a monitor hardware. If i could only somehow RMA or update the hardware on my 2566k that would be perfect. I reseted monitor , tried different combinations from youtube videos by pressing the buttons, cold boot , cru, ddu and other stuff, nothing works.
Best regards.

It appears to be a malfunction (RMA legitimate problem). It's not the cable / wrong resolution. More possibly malfunction in voltage inversion behavior, but uncertain.

Try
- Reset to factory defaults via monitor menu.
- Unplug & plug monitor for a full cold reboot of the monitor motherboard

Last resort:
- If you used ToastyX CRU, run reset-all.exe
- Deleting all custom resolutions, and/or use a different refresh rate
- Try creating a custom refresh rate about 1 to 5 Hz different than the current refresh rate.
