Question Can't get proper resolution on ultrawide after installing GPU

[padmjfp]

Got a "new" GPU, its used, but from what I can tell it was in good condition.

• GPU: https://www.amazon.com/AMD-Radeon-1...f=pd_ci_mcx_mh_mcx_views_0?pd_rd_i=B01N8XS96E
• CPU: i9 12900K
• MB: https://www.microcenter.com/product/671030/asus-z790-v-prime-wifi-intel-lga-1700-atx-motherboard
• 4 monitors, 2 running on integrated graphics (only because I dont have enough DP cables
  • 3x 24 inch, 1 of these on GPU
  • 1x 34 inch ultrawide - this one on gpu using HDMI to DP
• Issue:
  • When I dont have GPU driver, ultrawide outputs with proper resolution, but the other monitor connected do GPU does not
  • when I have GPU Driver, I cannot get proper resolution on ultrawide - the image is stretched, i need 3440 x 1440, currently showing 1980 x 1080
• What ive done:

• Uninstalled and reinstalled driver, with whole factory reset, and just updating driver
• Tried older GPU driver
• Reset OS
• Updated all drivers via windows update
• Reconfigured Monitors, except ultrawide because ultrawide on integrated GPU makes it very slow
• Tried putting custom resolution on GPU SW, but wont allow me to alter the UW resolution
• Enabled GPU scaling in GPU SW, gets me can get bigger resolution (3200x1800) but i need 3440 x 1440
• Went to display settings

does the 21:9 display work properly when it is the only display connected?

No, it only shows properly when I don't install the GPU driver, any other configuration, the resolution is stretched. But if I dont have the GPU driver, the 4th monitor doesnt show.

The only one configuration I haven't tried was running the UW on the integrated graphics, but I only got the GPU because running the UW on integrated used way too much ram.

have you tried setting options in the monitor's OSD?
it's possible that there is an option here that can interfere with your standard Windows/Adrenaline options.

what are the specific monitor models?

..because I dont have enough DP cables..

does this card even offer 4x DP connections?
which specific model card is it?

I reset all the settings, for the UW, still nothing, the other 3 are these.

yeah the GPU only has 4x DP
