The best cable to hook up a laptop to a TV is a standard HDMI cable — or a USB-C to HDMI adapter cable if your laptop lacks an HDMI port.
- Both laptop and TV have HDMI ports
- Your USB-C port supports video output (for adapter setups)
- Cable version matches your resolution needs (HDMI 2.0+ for 4K)
- Cable is under 50 ft without an active extender
- Your laptop has no HDMI port and your USB-C port is data-only
- Your HDMI cable version is too old for 4K@60Hz
- Cable run exceeds 50 ft without an active signal extender
Why HDMI Is the Right Choice
HDMI carries both audio and video over a single cable, works plug-and-play on nearly every modern laptop and TV, and supports resolutions up to 4K@60Hz with the right cable version. You don’t need drivers or extra software — just plug in and select the correct HDMI input on your TV.
Which Cable Version Do You Need?
| Setup | Works? | Need | Note |
|---|---|---|---|
| 1080p on any TV | Yes | HDMI 1.4 | Any standard HDMI cable works |
| 4K@30Hz | Yes | HDMI 1.4 | Limited refresh rate |
| 4K@60Hz | Yes | HDMI 2.0+ | Check cable and port version |
| USB-C laptop to TV | Yes | USB-C to HDMI adapter | USB-C must support video output |
No HDMI Port on Your Laptop? Use a USB-C Adapter
Many thin laptops ship with USB-C ports only. A USB-C to HDMI adapter or cable solves this — but only if the USB-C port supports video output (DisplayPort Alt Mode). Not all USB-C ports do. Check your laptop specs before buying an adapter. See our guide on whether your USB-C port supports video to confirm before you buy.
If your adapter connects but shows no picture, the port may be data-only. Read our USB-C to HDMI not working troubleshooting guide for step-by-step fixes.
How to Set Up the Connection
- Plug the HDMI cable into your laptop and TV
- Switch the TV to the correct HDMI input (e.g., HDMI 2)
- On Windows: right-click desktop → Display Settings → choose Duplicate or Extend
- On Mac: System Settings → Displays → Arrangement
Watch Out for Long Cable Runs
Standard passive HDMI cables work reliably up to about 25–30 ft. Beyond 50 ft, signal degradation becomes a real problem. For longer runs, use an active HDMI cable or a signal extender. Lenovo’s HDMI guide for laptops covers cable length limits and setup tips in detail.
Bottom line: For most people, a standard HDMI cable is all you need to connect a laptop to a TV. If your laptop is USB-C only, grab a USB-C to HDMI adapter — just confirm your port supports video output first. Match the cable version to your resolution target, keep the run under 50 ft, and you’ll have a reliable picture with no drivers required.
