DEX negotiating beyond 4k (4096x2160) with rather than standard 3840x2160

[ABHIRAMSHIBU]

I have a SAMSUNG TAB S9 and a SAMSUNG S24 ULTRA, both of them have the same bug with TCL and Sony tv. 

When I enable "High resolution for external display" it negotiates beyond 4K. I mean both the devices. 

I have tried different methods to convince android to lower the resolution from a beyond 4k to actual 4k resolution but all the methods at the end changes the DPI rather than actually changing the physical resolution.

It will be amazing if samsung will give me an option to set the physcial resolution of the display rather than the scaled resolution of the display.

Currently because of this I am using 1080p@60Hz than 2160p@60Hz. 

The problem with the beyond 4k resolution is that. it will negotiate 24FPS than the 60FPS which is ideal.

Please let me know how can I provide you logs or any more info to help debug this issue. I used to be a custom rom developer in the past so I can help you with these things.

Thank You.

Hi, It's not a bug. Rather I think it's by design. Please look into it. For this you would only need any non samsung branded 4k tv. Any non samsung branded dock. Now if you enable "Higher Resolution for External Display" under "I love dex" in good lock. You will find that it negotiates beyond 4K at 24fps with a quite bit of latency.

I don't see an error report under support section

Here is a pic of what is happening. I am using Dell WD22TB4 dock. Which is a thunderbolt 4 docking system

It does negotiate 60 fps with any other laptop or non samsung device (havnt tested samung laptop but I feel it will negotiate, it's a oneui isolated issue)
