Setup
- Dock the Switch 2 with its own power adapter; dock HDMI → card HDMI IN; card HDMI OUT → TV.
- Turn off System Settings → Display → HDR Output unless your card captures HDR.
- No signal? Set the card's EDID mode to Display (Elgato), turn off 120 Hz and Match TV power state, and try another HDMI cable.
- Set audio to stereo; a headset in the Switch 2 takes audio off HDMI.
- In OBS, add a Video Capture Device and pick the card. Handheld mode can't be captured over HDMI.
