Hi all!

Maybe I'm having a bad day, but I cannot for the life of me find how I can change the external resolution and refresh rate of Dex on an external display using my Tab S9 plus (TV - HDMI).

Any pointers much appreciated.

Ta!

Hi Mark. You can achieve 4K resolution and alter the refresh rates through the GoodLock Dex Module. GoodLock is available for download through the Galaxy Store.
