Radeon 5700 DVI to HDMI 2k 1140p?
Hi all,
I have an old Radeon 5750 card in my desktop that I have hooked up to my new 4k/ UHD TV.
I have tried a DP to HDMI cable, and now a DVI to HDMI cable, both are supposed to support 1440p (2560 x 1440), however I cannot get it to work... hence ending up here.

The video I watched that lead me here showed a CRU ability in the CCC.exe - my CCC doesn't have the CRU
Any ideas on how to force this?

CRU is a separate program: https://www.monitortests.com/forum/Threa...tility-CRU

You'll need to patch the driver to go beyond 165 MHz pixel clock with HDMI on a GPU that old: https://www.monitortests.com/forum/Threa...ck-Patcher

That worked!! I ran the patcher and suddenly I could just choose all the resolutions I wanted in the regular resolution picker, even higher res than I expected! Now running 2160p Big Grin

I am using a DP to HDMI converter too, so no separate sound required.

Thanks so much. Great software.
