OTHA Docking Station Compatible with Steam Deck, 6-in-1 Steam Deck Dock with HDMI 2.0 4K@60Hz, Gigabit Ethernet, 3 USB-A 3.0 and Full Speed Charging USB-C Port Compatible with Valve Steam Deck-HB0603

Please make sure that all of the following conditions are met for achieving 4K@60Hz output: 1. Used HDMI to HDMI 2.0/2.1 Cable shorter than 15 feet in length. 2. Manually debuged into desktop mode and set 4K@60Hz output. 3. Set 4K@60Hz Output it in-game Please DO NOT use HDMI to DisplayPort cables or adapters. We recommend that you connect your Power Adapter (45W and above) while docking your Steam Deck to ensure stable operation of the output video and external devices. If you need to use HDMI Switch (the 8K one is better), make sure that the HDMI cable at both ends of it does not exceed 6.6 Feet. When running big games, too high image can put a large burden on the Steam Deck, which may be not capable of handling such high power consumption. You can reduce the picture quality of the game appropriately to reduce the latency of the external device during the game.
