1. Why can't dual HDMI display at the same time?

a) Check the graphics card performance of the laptop or ask the computer manufacturer whether it supports extending two displays at the same time; b) Check the power management settings. In the power options, you can adjust the power plan and select "High performance" or similar settings; c) Check the display settings. In Windows, you need to go to "Display Settings" to configure the display. Make sure you have set the display mode to "Extend these displays" instead of "Show desktop only on 1" or "Show desktop only on 2"; d) Macbook only supports SST mode. If the color gamut of the two HDMI screens is different, it may cause single-screen output. It is recommended to swap the devices connected to HDMI1 and HDMI2; e) Mobile phones and iPads can only support single-screen display but not dual-screen display; It is recommended to connect to HDMI2 first when using mobile phones and iPads.
