Inverse ghosting caused by PC hardware?

[Anonymous768119]

Hi, so I've been experiencing intensified inverse ghosting for last couple of weeks and it just appeared like overnight. Everything what is moving on my screen leaves colored trails (mostly yellow, blue and red) for example scrolling, moving windows, running around corners in games. I tried vesa certified DP cable with shielding, different GPU and mobo, cable management, formats and still nothing so I am wondering if it's possible, that it can be caused by other components in my PC like CPU, RAM or PSU? Do any of you have any observations related to this?

PS. I have XL2546 and I tried different ama settings. DyAc off is somehow helping but I didn't pay extra money to play without it.

Strange instances of sudden inverse ghosting appearing/disappearing usually has been caused by monitor firmware bugs (or driver bugs).

Have you done anything such as switching resolutions breifly, switching refresh rates, creating custom refresh rates, turning on/off FreeSync, resetting monitor back to Factory Defaults, choosing a different monitor profile, or anything? (Buggy profiles exist) Those types of "troubleshooting" usually succeeds more on "Monitor screws up its overdrive" type of bugs. Cables don't create overdrive problems but port bugs might trigger them (if different ports use a different DisplayPort version). But more probably a monitor firmware issue. Your clue of turning on/off DyAc is a big clue on this.

Also, if you use a S-Switch type gadget and press buttons mid-game, factory reset/reprogram all the profiles, see if it helps.

Sometimes some users do really Rube Goldberg tricks to coax monitors not to trigger a bug, such as "turn off strobing, then factory reset, then turn off overdrive, then turn on strobing again if factory reset didn't turn it back on", or even creating odd resolutions like 240Hz with larger vertical totals, or testing a 230Hz mode, or selecting "sRGB profile" instead of "RTS profile", or other weird trickery.

Different mobo won't help, save your time. It's like trying to fix a broken leg by putting a band-aid on an arm -- far away from the needed troubleshoot area.

It can also be a monitor warranty claim too (has happened before).

You may wish to also open a ticket with BenQ too.

Factory reset didn't help. Also installing WHQL didn't change anything. I will claim warranty, because I expect more from monitor of this class and currently my eyes are bleeding. I think it can be somehow related to my AA issues and vibrating screen.

Thank you for your answer.
