Why is there a problem connecting monitors with hdmi?

Computer

When I connect it to the monitor with the hdmi line, the monitor turns off or has an afterimage, but it's not always like that, but sometimes it works well, so...

Sometimes it makes a high frequency sound

I don't think it's a line problem because it works well when you connect the hdmi line on TV, but does anyone know why?
