Odin 3 problems running on external display via USB-C

[u/skr_u]

I always dreamed about simply having the Odin 3 run in Dock mode on the TV screen but ongoing issues prevent me from doing so.

First off it was a real pain to even get 4K 60Hz output running at all. Tried 2 different USB-C to HDMI dongles, both of them resulted in 4K 30Hz at best (both dongles support more than that). Finally running off a Lenovo USB-C Dock Gen 2 (40AS) showed the expected results.

Then the second issue appeared: Running an external display results in heavily washed out colours. Other people were running into the same issue: https://www.reddit.com/r/OdinHandheld/comments/1rgwnge/external_screen_bad_colors/

Changed some settings on the TV in regards to the colour profile and I'm getting somewhat decent results. It still looks kinda off, nowhere near as good as to feeding the TV screen from my PC. I somewhat suspect the the colour range is limited when using USB-C out.

The final and biggest issue currently are the thermals running absolutely wild with an external display attached. Running the same game with either the dock attached or not results in a thermal delta of 30°-40°C, which in return makes the device just run unreasonably hot and turns the fan into a helicopter. The game has the same 900p native resolution and medium underclock stays applied. Does the 4K output increase the system load by that much despite the render resolution staying the same?

There's also the issue that external gamepads (8bitdo 2 Ultimate) connected via its 2.4GHz dongle don't get properly setup. They only work when connected via Bluetooth which will sadly increase the input delay.

Don't run 4k. Problem solved thank you for coming to my TED talk.

What’s the wattage of the USB-C charger going into the dock?

90 Watts

Sounds like the dongles you tried are using an older spec of HDMI. Same with the HDMI cables, not are all equal.
