The best way to get AV signal from a Windows 10 computer to a monitor or TV is using an HDMI cable. It reduces the clutter of too many wires with 3.5mm RCA cables.
A USB connection requires two connections. One for display and other for audio. An HDMI connection makes it easy to connect a Windows 11 PC to an external monitor. The crystal clear sound is another benefit of HDMI.
Once you plug the HDMI cable in the PC port and the other end on the TV, you should get a display. For some naughty reason Windows 11 may not detect the HDMI monitor.
In such cases, you can use this check-list to confirm if the hardware is working.
- Make sure the HDMI plug is not rusty. Otherwise, clean it with a steel blade. Normally these come with gold covering which prevents this problem.
- The PC and TV HDMI ports also should be clean. You can do the same as above if they are not properly visible.
- Make sure both the HDMI ends are seated properly on PC and TV. If you don’t get a display, remove them and plug it back in again.
- The display resolution and refresh rate on the TV and PC should be compatible with recommended settings.
- Otherwise, change the Windows 11 HDMI settings to suit the correct picture and sound.
- Make sure the right HDMI port on the external monitor is plugged in from the Windows 11 computer. You should see a green or blue indicator for that port if it is working.
- Use the right HDMI cable with correct specifications that suits your Windows 11 PC and TV.
- HDMI TV or Monitor should not have any screen problems.
If Windows 11 is not detecting an HDMI monitor, then you can follow these fixes.
