Graphics Cards

[saadfk]

Hi i have an AMD RADEON RX 6600 running 4 screens

the 4th screen to be linked always seems to have low resolution issue, crisp image and i don't know how to fix it or if it's fixable.

I played around settings all I could, I bought the most expensive 8K cables I could find

(3 DPI ports and 1 HDMI port on the card)

can this be fixed or is there some limitation on the card for multiple screens that i'm not aware of.

thanks for responding.

1. Not using an MST, all of them are connected with very expensive 8K /4K cables via the native ports on the card

2. All screens are set to Native res + refresh as you can see from my DXDIAG log above. Reducing them doesn't fix it
3. didn't do anything for me , i just did now
4. doubt that i've switched the ports and it's always the last one to be branched that doesn't work well. 

PLEASE HELP :'(
