I've installer CRU 1.5.3 on my W11 PC, I own a ASUS TUF GeForce RTX 5070 Ti OC Edition with a LG UltraGear 40WP95X-W (5120 x 2160 pixels, 39.70") monitor.
CRU doesn't detect it correctly, and resolution ara also missing.
Already tried reset-all.

Looks fine to me. Did you check the extension blocks? 5120x2160 is usually in the DisplayID extension block.

Thanks a lot, haven't seen that I can click on these lines to open sub-screens.

[Framerate]

For those of you using non-standard framerates like 47.952fps, 48fps, or anything else, I was wondering how you get audio to external speakers?

I’m using an AVR with external speakers and Google AI is adamant that AVRs, as well as HDMI splitters etc., will at minimum introduce microstutter or microjudder to custom framerates, if not convert them to 50fps or 60fps or create a black screen.

Meanwhile, end users are saying that it will work; however, they are probably going by eye test and I doubt they have ever tested it for microstutter or microjudder. Google AI also recommended “extend this display” at one point, but then at another said that it would also create these issues and possibly a lot of audio sync variance as well.

I want to interpolate mkv movies to 47.954fps and 48fps and output them at either 1x or 2x Hz without getting video artifacts or bad audio sync variance, and am wondering the best way to do it. I have an audio sync measurement device so I can correct for bad sync latency, but not for bad drift or variance. I need a steady number, even if that number is big.

The video signal is a constant stream of data at a fixed rate, so there can't be stutter in the video signal itself, and sending audio to an AVR or splitting the signal wouldn't change that. Any visible stutter or judder would be on the software side. The biggest challenge is perfectly synchronizing the frame rate of the video player to the refresh rate of the display. If the video player and display both support variable refresh rate (FreeSync/G-SYNC), that would be the best solution.

Thanks for your help. My display is an LG C5 which has a framerate matching setting I believe, "true cinema." Anyway in PC mode it's supposed to not alter the incoming framerate anyway.

As far as Freesync/G-sync, want to avoid those because I think they introduce artifacts or microstutter/judder, at least they used to.
