Can anyone helpme figure out what's happening?

Probably another limit in the driver. You should get a proper adapter so you don't need to use the patcher. Passive adapters are limited to 165 MHz pixel clock. You need an active adapter, or use HDMI directly if you can. In the meantime, you can use CRU to reduce the refresh rate to 50 Hz to stay under the 165 MHz pixel clock limit.

in my testing, the old rx 570 steel got
2560x1080@75hz
4k@30hz

the rx 5600xt
2560x1080@50hz (with a blurry text)
4k@60hz

i don't fucking know what is happening lol
also, I did the testing with 5600xt with and without the custom drivers, the result is the same, even tried to unninstall every thing.

before the passive adapter worked both freesync and 75hz

Edit: 2560x1080@54hz is working with clear text \o
