A:Answer If the HDMI ports work with a gaming console or connected to a laptop/PC, this would indicate the port hardware is functioning properly. The most likely reasons your Nintendo Switch won't connect are a handshake issue, an incorrect video resolution, or a faulty cable, even though your PlayStation 5 works. The Switch may be sending a signal that is incompatible with the monitor's current settings, or there could be an issue with a specific cable or port.
