To switch to HDMI on Windows 10, press the Windows logo key + P on your keyboard to instantly open the Project menu, then select "Duplicate," "Extend," or "Second screen only" to send video to your TV or monitor. This is the fastest way to switch to HDMI on Windows 10 without digging through menus.
How to switch to HDMI on Windows 10 instantly with Win+P
The quickest method to get your external display working is using the Windows logo key + P shortcut. This opens the Project menu, where you can choose how your PC screen and the HDMI display work together. Select "Duplicate" to show the same content on both screens, "Extend" to use both as one larger desktop, or "Second screen only" to turn off your laptop screen and use only the HDMI display.
Connect your PC to the HDMI display
Before using any software settings, make the physical connection. Plug one end of the HDMI cable into your Windows 10 PC's HDMI port and the other end into an HDMI input port on your TV or monitor. Ensure both the PC and the external display are powered on. If your TV has multiple ports, you may need to switch from HDMI 1 to HDMI 2 to find the one your PC is plugged into. If you've recently upgraded your system, the process to switch to HDMI on PC Windows 11 has a slightly different interface.
Manually detect the display if it doesn't show up
Windows 10 should automatically detect the external display after you plug it in. If nothing appears, go to Start > Settings > System > Display and click the "Detect" button under "Multiple displays." This forces Windows to search for any connected display it may have missed.
Switch audio to your HDMI device
Once video is working, you may need to route sound to your TV or monitor's speakers. Right-click the speaker icon on the taskbar, then click the arrow next to the speaker option. From the list of available audio output devices, select your HDMI device, it may appear as "Digital Audio Out HDMI" or the name of your TV. Alternatively, go to Start > Settings > System > Sound, and under "Choose your output device," select the HDMI device to set it as the default.
Adjust HDMI display settings for the best picture
For optimal image quality, right-click the desktop and select "Display settings," or go to Start > Settings > System > Display. You can also adjust scaling to make text and icons the right size, and if you're using multiple displays, drag and rearrange the display icons to match their physical positions on your desk.
Troubleshooting common HDMI problems
If you see a "no signal" error, start by checking that the HDMI cable is securely connected at both ends and undamaged. Try a different HDMI cable or a different HDMI port on your PC or display. Update your graphics drivers regularly, as outdated drivers can prevent HDMI output from working correctly. Finally, restart both your PC and the external display to clear any temporary glitches.
A note on connecting game consoles to your PC
PC HDMI ports are typically output-only, meaning they cannot receive video input from devices like a PS5, Xbox, or Nintendo Switch.
