MAG251RX problem (and questions)

[zero1zero]

Hello,

I bought this monitor and downloaded the recommended color profile, but cannot seem to be able to do the native resolution hack in CRU. I followed all of the steps but can't see "native" under the Radeon app nor in Windows display settings after restarting. Furthermore, when I apply the CRU settings, the color depth changes from 10bit to 8bit (and 10bit cannot be selected). This is using Displayport.

Is the CRU hack only for Nvidia graphics cards? Or, perhaps only for HDMI? I can't find much info about this other than a couple of threads here and the youtube video mentioned therein.

The monitor takes longer than I'm used to for it to show a picture when starting the computer or resuming from hibernation and, when it does, windows are resized (smaller and same size) every time. Does this have something to do with the resolution not being native?

Variabe refresh rate isn't available under windows graphics options (it was for the XB273X), and Radeon software says that freesync isn't supported for the monitor. I read that this monitor was both G-sync and freesync compatible with VRR, so why could this be happening?

Is it possible to have 12bit HDMI with 240hz? That would be ideal because I love the colors on this monitor.

And finally, when I performed an input lag test at lagom.nl with both the XB273X and MAG251RX side-by-side, there was no difference between them in the pictures that I took. Both monitors had the exact same timing. Could this mean that my graphics card was/is handling the scaling regardless of monitor? I have GPU scaling disabled in the Radeon software, but don't know how reliable that is.

Thank you for reading and any help in advance.

I know with the CRU hack you need to delete ALL the existing resoltuions in the detailed resolutions box, then add 1080p 240hz. Also untick all the checkboxes on the very left. Restart is not needed, just use the restart64.exe
And yeah you do lose 10bit, but if you use reduced lcd you still can use 10bit. i think it has to do with the pixel clock being too huge for 10bit. 10bit makes zero difference in 99% of situations. literally.

I dont even use the CRU, i let the GPU do the scaling, so yeah..
