I’ve had some issues with USB-C to HDMI in the past with other devices, particularly when there were multiple connections between the “host” device and the display. I wasn’t sure if this was a common problem because it wasn’t something dbrand supported, I was doing something wrong, or I had a defective adapter. It sounds like there’s a good possibility it’s a defective adapter.
I don’t see anything wrong with the pins/ports on either side of the adapter, the Docking Station’s cable, or the Steam Deck. Everything works for me (including charging, USB peripherals connected to the Docking Station, or connecting the Docking Station to other devices instead of the Steam Deck), except for HDMI out to monitor/TV when using the Kill switch adapter.
Just to confirm, you’re connecting the Docking Station to a monitor/TV via HDMI (not DisplayPort)?
Thanks for confirming. Do you know when you got your Killswitch? Maybe I received an older model that doesn’t support HDMI for some reason?
