Steps
Plug one end of the HDMI cable into the HDMI port on your laptop or desktop. Plug the other end into a free HDMI port on the TV and note the port number.
Turn on the TV and press the Source or Input button on the remote. Choose the HDMI port you used, such as HDMI 1 or HDMI 2.
On the laptop, press Windows + P. Pick Extend to use the TV as a second monitor, or Duplicate to show the same screen on both displays.
If the TV stays blank, open Settings > System > Display and click Detect. You can also check that the correct HDMI input is selected on the TV.
In Display settings, drag the monitor icons so they match the TV's position on your desk. Click Apply to keep the layout.
Select the TV in Display settings and set Resolution to the recommended option. Open Advanced display to choose a supported refresh rate.
To send sound to the TV, click the speaker icon in the taskbar and choose the TV or HDMI output. Test the volume before playing a video.
Keep the laptop connected to power for long sessions. Adjust sleep settings under System > Power so the screen does not turn off during use.
Tips and common mistakes
Use a standard high-speed HDMI cable; a loose or damaged cable is a common cause of a blank screen.
Press Windows + P again if the TV stops extending after a restart.
Match the TV resolution to its native setting to avoid blurry text.
If the laptop has only USB-C, use a USB-C to HDMI adapter that supports video.
Questions
Do I need a special HDMI cable?
No. A standard HDMI cable works for most TVs. Use a high-speed cable for 4K screens.
Can I use the TV as a second monitor without a cable?
Yes, if both devices support Miracast or you use a wireless display adapter. HDMI is usually more reliable for a fixed setup.
Why does the TV show no signal?
The TV is probably on the wrong input, or the cable is loose. Check the input source and reseat both ends of the cable.
