Samsung DeX External Display Resolution

[wywen]

Does Samsung DeX support 2K (2560x1440 @60Hz) x or 4K @60Hz External Display Resolution? (S22 Ultra connected to external monitor with 2K native resolution via HDMI through USB-C dock supporting 4K @60Hz)

I only see 1920x1080 or 1600x900 in the Samsung Dex Display Resolution Settings?

If so, how do I set it to 2K?

If not, will Samsung Dex support the higher display resolutions soon?

You need to install a third party app called GoodLock from Samsung Store.

1. Open it
2. Select 'life up' section
3. Find 'MultiStar' plugin.
4. Install it
5. MultiStar plugin will show first in the GoodLock app 'life up' section
6. Select it and open 'I ❤️ Samsung DeX' option
7. Enable 'High resolutions for external display'

this worked for me. s23, M7 smart monitor,  USB gen 3.2 gen 2 cable. Otherwise, FHD was supported. I belive UHD should be available without installing MultiStar. Can't samsung updates help?

I am unable to find GoodLock on the Play Store or Galaxy Store. It seems as though it has been removed from these stores.

I had the same issue.  I used a 2016 monitor for whatever reason did not pass 1080p.  I brought a newer model now and multistar now picks up 4k/30.  However, i still cant finger out how to get 60 hz.
