The easiest way to connect a laptop to a TV is an HDMI cable: plug one end into the laptop, the other into the TV, and select that HDMI input on the TV remote. Picture and sound travel together. If your laptop has no HDMI port, use a USB-C adapter, or go wireless with screen mirroring or a Chromecast.
Pick your method
| Method | Best for | What you need |
|---|---|---|
| HDMI cable | Football, films, presentations; most reliable | HDMI port on laptop and TV, one cable |
| USB-C to HDMI | Newer slim laptops and MacBooks | USB-C port that supports video, adapter or cable |
| Wireless mirroring (Miracast, AirPlay) | Quick sharing, no cables | Smart TV or streaming stick, same Wi-Fi |
| Chromecast / Google TV | Casting a browser tab or video | Chromecast or Google TV, Chrome browser |
| VGA | Old laptops and older TVs | VGA port on both, separate audio cable |
For anything long or important, use a cable. Wireless can lag and drop during live football or a presentation.
HDMI: step by step
- Plug the HDMI cable into the laptop and any HDMI port on the TV.
- Turn on the TV and press Input or Source on the remote. Choose the matching HDMI port.
- The laptop screen should appear within a few seconds. If not, press Windows + P and choose Duplicate.
- Picture cut off or blurry? In Settings > System > Display, set the TV’s recommended resolution.
This works on Hisense, TCL, Samsung, LG, Vitron, Skyworth and other TVs, smart or not. A cheap standard HDMI cable is fine for 1080p; for long runs or 4K, see choosing an HDMI cable for laptop to TV.
No picture, “No signal” or no sound? Work through laptop won’t connect to TV via HDMI.
Getting sound through the TV
HDMI carries sound, but Windows doesn’t always switch to it.
- Windows: click the speaker icon on the taskbar, open the output list (the arrow next to the volume) and pick the TV’s name. Or go to Settings > System > Sound > Output.
- Mac: open System Settings > Sound > Output and choose the TV.
Sound still on the laptop? That’s the output setting nine times out of ten. VGA never carries sound, so connect a 3.5 mm aux cable from the laptop’s headphone jack to the TV or a speaker.
Duplicate vs extend (Windows + P)
Press Windows + P to choose:
- Duplicate: TV copies the laptop. Best for films, football and church or school presentations.
- Extend: TV becomes a second screen, so you can show slides while reading notes on the laptop.
- Second screen only: laptop screen off, TV only.
On a Mac, open System Settings > Displays and choose Mirror or Extended Display.
Wireless options
- Windows + K connects to Miracast-capable smart TVs and streaming sticks. Most Android and Google TVs and many Samsung and LG TVs support it.
- AirPlay sends a Mac’s screen to AirPlay-compatible TVs and Apple TV.
- Chromecast: in Chrome, open the menu and choose Cast, then pick the TV.
Both devices must be on the same Wi-Fi network; a phone hotspot works but uses bundle quickly for video. Full steps are in connecting a laptop to a TV wirelessly.
Older laptops: VGA and adapters
Old laptops may only have VGA (a blue, 15-pin port). Use a VGA cable if the TV has a “PC” input, or a VGA-to-HDMI converter for newer TVs. Slim laptops with only USB-C need a USB-C to HDMI adapter; check that the port shows a display or Thunderbolt symbol.

Quick answers
Plug an HDMI cable into both, choose the right HDMI input on the TV, then press Windows + P and pick Duplicate if the picture doesn’t appear.
Click the speaker icon on the laptop’s taskbar and choose the TV as the output device. On a Mac, choose it under Sound > Output.
Use a USB-C to HDMI adapter, mirror wirelessly with Windows + K or AirPlay, or cast from Chrome to a Chromecast or Google TV.
