I recently updated my Official Steam Deck dock to it’s newest firmware and I’ve had nothing but problems with it since. Before the update, I had no problems and had my monitor plugged in via the DP connection. But after the update the steam deck kept flickering between on and off on the main screen and I got nothing but black on the external. If I switch to desktop mode, the external screen works fine, but I go back to gaming mode and it’s not working again. Also if I switch to HDMI, the entire screen jitters regardless of the mode. Is there a way to reinstall the dock update or roll it back?
