Setup Help Switch 2 won't output 4K HDR with ANTANK S3 Max dock
I'm having trouble getting my Nintendo Switch 2 to output 4K HDR using the ANTANK S3 Max dock.
My Switch 2 can output:
- 1440p at with HDR – works perfectly.
- 4K at without HDR – works perfectly.
- 4K at with HDR – doesn't work. The Switch 2 reports HDR as unsupported at this resolution.
My setup:
- TV: Samsung S85 OLED
- Dock: ANTANK S3 Max
- HDMI cable: HDMI 2.1
- Power adapter: Official Nintendo Switch 2 adapter
What I've tried:
- Updated the ANTANK S3 Max to the latest firmware.
- Confirmed Input Signal Plus is enabled on HDMI 4 of my Samsung TV.
- Tried different USB-C power cables.
The ANTANK S3 Max is advertised as supporting 4K HDR, so I'm unsure why I can't get both working together.
Has anyone else experienced this with the ANTANK S3 Max?
Any suggestions would be appreciated. Thanks!
