Custom Resolution Utility (CRU)

The image seems to be GPU scaled and skewed/distorted horribly, as soon as I set it above 100hz (so, 1080p above 100hz just doesnt display, lower res 101hz displays but skewed it seems to be a LVDS limit of 240mhz pixel clock in play here?) as shown here:

I know I don't frameskip on 240hz, cannot test further up as it doesn't want to sync on 360hz and 420hz
I cannot remove 1080p with CRU at all for some reason, running on W10 21H1, it still displays 1080p 60hz :/
Is there any way I could salvage the panel and perhaps take advantage of these higher refresh rates with some LVDS to HDMI/DP adapter and use it on my desktop?
Would be lovely if Toasty could chime in on this!

Laptop panels normally don't have scalers and can't display lower resolutions without GPU scaling, so you can't use a lower resolution to get a higher refresh rate. I don't think any sort of adapter would help because you will still be limited by whatever you can get at the native resolution. You might be able to use a lower vertical resolution like 1920x540 to get 200 Hz, but the image will be repeated until it fills the screen.
