Motorola's "Ready For" desktop mode outputs 4K at 60Hz with no specific adapter or additional software required. Why doesn't DeX do this?
DeX requires that you have Android 12 and install Good Lock and the MultiStar module to output just 1440p on third party adapters - DeX doesn't support 4K, period. Good Lock is not available in every region so this also locks out a large portion of DeX's users from ever running more than 1080p.
Samsung, take note: Motorola's desktop mode has truly surpassed DeX at this point and clearly demonstrates the anti-consumer limitations Samsung has imposed on DeX.
If Motorola can deliver a desktop mode with features like this (not to mention a far better UI), there's no reason Samsung can't.

Looks like your wish has come true! Dex now supports 2160p60 on One UI 5 (Android 13).
Thank you so much and also to Helenna who delivered your voice and the Devs who worked on making it possible.
