Can't output native 2560*1600 60hz?

[ToastyX]

2560x1440 @ 60 Hz requires dual-link DVI or HDMI 1.4 as well. Some monitors can accept single-link DVI signals beyond 165 MHz pixel clock, but that's non-standard. 2560x1440 @ 40 Hz and 2560x1600 @ 35 Hz is possible with single-link DVI, and CRU can add HDMI support if the monitor can handle an HDMI signal, but your GPU makes this hard to test because the driver might not support custom resolutions or EDID overrides with the method CRU uses. You can try using CRU, but if it has no effect, you'll have to use the more complicated method described here: https://www.codeground.net/howto/overrid...-registry/

I might be able to help with that method if you export a file using CRU and post it here.
