Would appreciate your reply since I can still cancel the order today if that won't work either.
In theory, that should work. That adapter is certainly capable.

if someone uses faceit anticheat and you get an error stating that you do not have a video driver installed after restarting your pc. Then you need to install the latest bios for the video card. (Don't ask me how to do this, there are many guides on the Internet)

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 Sad

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

Hey toasty I am having issues regarding signature blocking my 5600xt mod bios from being accepted by 20.5.1. Do you think this should stop that from being an issue? I tried it and it doesn't seem to make a difference. Is there anything that I can do that would confirm that the signature requirement has been removed from the driver? Thank you

The BIOS signature patch is for Polaris only.

RE: AMD/ATI Pixel Clock Patcher
is there a way to bypass it for other cards as well?
