I use a 5.5-inch 1440x2560 LCD to connect to the PC, but it cannot display normally. How to solve it?

Ensure the HDMI port of the PC can output normally.

The PC only connects the LCD as a display device and does not connect other monitors.

Connect the power cable first and then the HDMI cable.

Some PCs also need to be restarted to display properly.

Does the screen not automatically rest, or do I have to execute a command to rest the screen?

It depends on the system, if the system has hibernation, the screen will also be black. If it is the official system of Raspberry Pi, the default is about ten minutes without action to have hibernation.
