Have you tried reducing the front porch and sync width to reduce the horizontal total further? Try multiples of 8 for horizontal values.

Welcome back, ToastyX!

I tried but if I do that, the screen seems to split into 3 pieces of vibrating rectangles I forgot what values I tried, though. But if I went past that vibrating rectangles range, and went any lower, the resolution completely dissapeared from the CCC.

*edit*
the absolute lowest I can get is front porch 40 and sync width 24 using the 8 multiple you mentioned. Pixel clock 471.56 and HT 2625, still artifacts at 120hz.

If I go 32 and 16 for the two values, for a HT of 2609, the refresh rate disappears from the CCC.

Looks like its the HT causing the refresh rate to vanish. Cant go below 2625

I think I'll just be happy with 115hz. 2560x1440 doesn't give me fast enough FPS anyway, TBH.

I do have a question btw.
You mentioned in an earlier post about the displayport 1.1 limits of 360 MHz for 8bpc and 480 MHz for 6bpc for 4 lanes.

But I checked the Benq product page and it says all of their recent monitors use displayport 1.2 ports. But you said that the Benqs are all displayport 1.1 (except the XL2730Z). If they were really DP 1.2, I should have 8 bit color up to 600+mhz and should not have a 480 MHz hard pixel clock limit

Did Benq unintentionally lie or is it just because a DP 1.2 cable works in a 1.1 port?
