To connect a laptop to a TV with HDMI, connect the cable to the laptop's video output and the TV input, select that input on the TV, then set the computer's display mode and audio output. For many simple issues, checking these three areas is more useful than changing multiple settings. This guide focuses on a wired connection and Windows 11. TV menu names may differ by model or software version.
Check the ports and cable before connecting
Check that both devices have HDMI. If the laptop only has USB-C, the connector's shape does not establish video-output support. Check the laptop specifications for video support and adapter compatibility. Use an undamaged cable that reaches without tension. Insert connectors without force and keep the cable clear of walkways.
The specifications for the 50-inch 50SST-8920QI9 television list HDMI. This model has an Ultra HD display and a 60 Hz refresh rate. These specifications alone do not guarantee support for every laptop resolution, refresh rate, or feature. The available setting depends on the computer, cable, and TV input together.

Select the TV input and Windows display mode
After connecting, select the HDMI input corresponding to the connected port in the TV's input list. If several inputs are present, match the number on the casing to the menu option. Selecting another HDMI input can show No Signal even when the cable is connected correctly.
In Windows, press Windows + P. Duplicate shows the same picture on both screens, while Extend expands the desktop. With Extend, you may need to move a window onto the second display. Second screen only sends the display to the second screen. For further adjustment, open Settings, then System, then Display. If the screen is not detected, check Detect under Multiple displays.
Where should you start if picture or sound is wrong?
Symptom | First check | Next action |
|---|---|---|
No Signal message | The selected input number | Check cable seating, then test another working cable |
Only the desktop background appears | Windows Extend mode | Move the window or select Duplicate |
Picture but no sound | The selected audio output | Select the TV or HDMI output in Sound settings |
Text or picture size looks wrong | Settings for the selected display | Check resolution and Scale in Display settings |
For audio, open Settings, then System, then Sound, and select the required output. Also check computer and TV volume and mute settings. If the TV is not listed as an output, recheck the connection and display detection. Changing one item at a time helps identify the cause. A full reset is not a suitable first step for an incorrectly selected input.
