What Xiaomi TVs are suitable for use as a monitor

Not all Xiaomi TVs are equally good at being a monitor.

• 🔹 Screen resolution: models with 4K (3840×2160) They're good for design and video, but they can put a lot of pressure on weak graphics cards. HD (1920×1080) frequent 120 Hz (e.g. Mi Mi) TV 5 Pro).
• 🔹 Delayed input (input lag): for games critical indicator below 20 ms. TV X makes up ~15 ms in game mode, and budget models can reach 40 ms.
• 🔹 Connection ports: availability HDMI 2.1 lets out 4K@120Hz (relevant to Mi) TV Q2), USB-C It simplifies the connection of laptops.

3. If no option: In Additional screen settings, click Adapter Properties → tab Monitor → Uncheck the tick to Hide modes that the monitor cannot display.

Select the "Game" mode, or "PC Mode"|Disable post-processing of the image|Install native-resolution TV|Check the scaling setting (overscan)|Update the TV firmware-->

4. Optimization of color rendering

To work with graphics or video, it is important to adjust the color profile. → Picture → Colour:

• 🎨 Color Temperature: Select Standard Temperature (6500K).
• 🔍 Color space: set up BT.2020 for 4K HDR or sRGB for office tasks.
