I purchased the pro display for my 7640U framework and in Windows 11 it doesn’t look like it supports Dynamic refresh rate. I have the latest drivers installed. Is there anyway to get this enabled?
Try enabling VRR under the Graphics settings and updating your graphics driver to the latest (try the one supplied by Framework and the latest official from AMD).
If none of that makes it show as supported, the display probably needs adding to the drivers whitelist by AMD. Pretty sure this same issue happened with the original 120Hz display.
Edit: Yep, happened with the prior display: Windows Dynamic Refresh Rate not supported on 2.8k Display?
