This is my setup so far. Was going to use Bluetooth but it doesn't work well. I found out how to disable the internal Bluetooth and use a USB though. But that still isn't good (I can only reliably use one controller) so the Bluetooth is specifically for wiimotes and my USB hub is for my 2.4ghz controllers
I noticed that the HDR on the desktop works amazingly well with all apps (Including SDR ones.) seeming to fully make use of my display although HDR in game mode seems to be game-dependent with most stuff looking better in SDR and if I exit game mode with HDR enabled, The colors look messed up until I either go back into game mode or reboot.
