I am not being able to use 4K resolution from Chrome on Macbook pro.
I have tried following many online instruction but hasn't been able to get this working.

If you do not have a 4k display and your macbook pro is not doing vp9 decoding for stadia, the 4k option will be disabled and not usable unfortunately
Also try to use the stadia enhanced chrome plugin. You can force vp9 and 4k with it. Do note that if your macbook can't decode the stream fast enough you will experience great visuals but with stuttering and massive input lag.
