How to set up HDMI on a Xiaomi TV: a complete guide with photos and tips

Connecting devices via HDMI to a Xiaomi TV seems like a simple task — just plug the cable and turn on the source. But in practice, users face a lack of signal, incorrect resolution or sound problems, especially for the Mi TV 4S, Mi TV Q1 and Mi TV A Pro models, where the HDMI settings are hidden deep in the menu.

In this article, we'll look at not only the basic connectivity, but the hidden HDMI settings that the manufacturer doesn't advertise, how forced 4K affects picture quality, why the TV can't see the console through HDMI-ARC, and how to get around the limitations of Dolby Vision when connecting game consoles, and a cable-device compatibility table that will save you time for experimentation.

1. Choosing the right one HDMI-port on Xiaomi TV

Not all HDMI ports on Xiaomi TVs are the same. For example, in the Mi TV Q2 75 models, the HDMI 1 port supports eARC (for sound systems), and HDMI 2 is optimized for game consoles with ALLM (Auto Low Latency Mode). If you connect the console to the wrong port, you lose some of the features.

4. In Color Mode, select: RGB for PC (full range 0-255); YCbCr 4:4:4 for consoles (best text detail); YCbCr 4:2:0 for movies (fewer artifacts with high bitrate).
