That monitor is single-link DVI. It will not display dual-link DVI signals correctly. Any resolution over 165 MHz pixel clock is sent as a dual-link DVI signal unless the driver is patched: https://www.monitortests.com/forum/Threa...ck-Patcher

That means the scaler can't handle the resolution. Sometimes using different timing parameters will help.

Now I feel like an idiot. Anyways, I solved it by setting LCD-Reduced at 74.990hz. Hope this helps someone down the line.

That's one way to keep the pixel clock under 165 MHz, but the video card won't reduce the memory clock when idle with a lower vertical blanking/total.
