Does it just need X bandwidth spare?That would depend on the bandwidth available. Pixel clock limit would be <pixel clock limit> * 8 / <bpc>, so like DisplayPort HBR2 would be 720 MHz * 8 / 10 bpc = 576 MHz, and HDMI 2.0 would be 600 MHz * 8 / 10 = 480 MHz. You might need to go a few MHz lower with NVIDIA for some reason. If that doesn't work, then it's purely a driver or GPU limitation. (03-30-2023 04:55 AM)Mussels Wrote: 1. Is there any recommended settings to adjust like the horizontal rate in the Gsync/Vsync settings? - i've seen no guides mention this, other than one standalone post from ToastyX to state keeping it at a static valueHorizontal rate in the range limits doesn't matter and isn't used for anything as far as I know. Variable refresh rate uses the maximum refresh rate's timing parameters as the base. (03-30-2023 04:55 AM)Mussels Wrote: 2. Is that tearing me putting the wrong porch/sync width settings in, or is that just the limit of the display? I've tried the different preset profiles and some random adjustments, but no luck improving that.That's weird. I would have thought that was a monitor limitation. That sounds like a driver bug. |
