Custom Resolution Utility (CRU)

[LordX]

I am a HTPC user, and would like to tweak my 23.976 resolutions to try and get as close to audio clock as possible so that I don't have any dropped/repeated frames with MadVR.

I don't mind using CRU or even the Nvidia custom resolution tool, but I have a serious problem: I Don't know what the heck any of the values mean aside from resolution and refresh rate.

Porches, blanking etc etc.... Especially with the CRU tool, I have literally no idea what I am doing.

The Nvidia default for 23.976 is pretty close - 1 dropped frame every 50 or so minutes. Which I can live with if there is not an easy way to test some other custom res.

I tried using the pixel clock calculator, but don't know what to do with the values that I got. (https://www.monitortests.com/pixelclock....rtvlines=1)

My setup: HTPC (Nvidia 3080 driver version 456.71), Denon X3400H receiver, Sony 285ES 4k Projector.

UPDATE: I tried adding a detailed resolution with CRU. It added the resolution under the PC section of the Nvidia resolutions. When I select it, and apply, it blanks for a second, saying it is applied, but then just shows the resolution selected as the one up under HD, SD, 1080p section of the Nvidia drivers.

I don't mind using the Nvidia custom resolution tool, but need to know how to convert the information the web page is telling me.
