Certainly my case is niche, but if anyone has ideas, I am interested.
What happened was that my system/card went from supporting 8560x1440 and now can only support 6000x1440 at best.
If I plug in all 3 monitors (3440x1440 via DP, 2560x1440 via DP and 2560x1440 via DVI) only the 2560s will function... and barely at that as the system tries to figure out what's going on with the center 3440, but can't get things to all work at the same time.
Things I have changed that were changed back: drivers, monitoring software (nv inspector), various monitor settings. None of these had any positive effect.
Thing I have changed that cannot be changed back: recently had my power supply die and had to replace with a backup.
Other things I have tried: re-seating the card, playing with the order of attaching the monitors, other pointless things like windows power settings confirmed.
Next thing on my list: bios check. I need to check and see if something is affecting my performance settings in the bios... but I'm not sure what would affect this.
I'd really like to avoid having to RMA the card, but I'm not sure why this issue might have come on suddenly.
Open to ideas and other methods of trouble-shooting. Thanks!
