Why does the monitor turn off or have an afterimage when connected to the monitor with hdmi wire?

hdmi monitor computer afterimage

When I connect the monitor with hdmi wire, the monitor turns off or afterimage occurs. It's not always like that, but sometimes it works. That's why sometimes it makes high frequency sounds.

I don't think it's a good problem because it works well on TV.

Does anyone know why?

If it's an old monitor, it may not be able to receive hdmi signals

It can happen if there's a problem with the graphics card
Check your graphics card, too
