Custom Resolution Utility (CRU)

[Jen]

Good day ToastyX

So I have several questions about HDMI 1.4 and pixel clock limits.

Im currently using a dual gpu system (non mux) with an intel uhd 630 and gtx 1650, and I wanted to know if custom resolutions above 300 or 340 mhz would work, since the hdmi out comes from the intel gpu. Im aware there isn't a pixel clock patcher for intel, but I think I heard you mention something about HDMI support display block a while ago. Would setting the max TMDS clock bypass this? I just want to make sure since my new 1440p 360hz monitor still hasn't arrived and I plan to use a custom resolution of 1920x1080@250 for competetive gaming, since that's the max on hdmi 1.4 at 10bit with yuv 4:2:0.

I used this tool to figure that out: https://tomverbeure.github.io/video_timings_calculator

Also Regarding this tool, the 1920x1080@250 is 543 mhz, obviously far higher than the advertised limit for udh630 and hdmi 1.4; however, It claims that it's possible to work either way. Is this because it doesn't count the gpu pixel clock limit or is this a program error?

Thanks in advance
