How to connect a laptop to a TV — wired and wireless options
June 1, 2025
In this step-by-step guide, we’ll show you how to connect your laptop to a TV so you can watch Netflix, view your vacation photos, and display other content on the big screen. There are quite a few ways to do it, but we’ll keep it simple and just focus on the most widely used methods. The right method for you will depend on a couple of different things, including the ports that are available on your TV and laptop. Let’s get started.
QUICK ANSWER
You can connect most laptops to a TV using a simple HDMI cable to mirror the screen. If you're looking for a wireless solution, consider Google Cast instead. Ensure your Chromecast-enabled device and laptop are connected to the same Wi-Fi network. Then, launch the Chrome browser, click on the three-dot menu icon, highlight Cast, Save, and Share, pick Cast, select what you want to stream under Sources, and select the device you want to stream to.

How to connect a laptop to a TV wirelessly, without HDMI
If you don’t want to deal with pesky cables or can’t reach the screen’s ports, wirelessly connecting your laptop to the TV is the way to go. However, you need a media streaming device like Chromecast with Google TV, Google TV Streamer, Fire TV device, or Roku streamer. A Chromecast or Google TV device is probably the simplest option.
We will use a Chromecast with Google TV to formulate these instructions, but the steps are pretty similar across the board.
How to mirror a laptop to a TV wirelessly:
- Plug the Chromecast or Google TV device into the TV and set it up.
- Skip this step if you own a TV with Chromecast functionality built-in.
- On your laptop, open the Chrome browser and click the three-dot menu icon in the upper-right corner.
- Select the content you want to cast via the Sources drop-down menu.
- Select the Chromecast you want to cast to. Roku TV devices should also appear.
Keep in mind, this often works across different platforms. For example, we’ve successfully mirrored our laptop screens from Windows to Roku TV devices using the same steps above. We’ve also mirrored MacBooks to Roku TV using AirPlay. Roku seems to be much more versatile. Those with an Apple TV will have a harder time, though. Only Apple devices can stream to Apple TV boxes, at least officially.
How to connect a laptop to a TV with an HDMI cable
Using an HDMI cable is the simplest and easiest way to connect your laptop to a TV. All you need to get the job done is an HDMI cable, which you can get on Amazon for fairly cheap. An HDMI cable can handle both audio and high-resolution video, so it’s great for streaming your favorite TV shows.
To make this work, your laptop and TV must have HDMI ports. If they aren’t super old (or super new, for that matter), there’s a good chance both have it on board. Laptops often come with no HDMI port, in which case you can find a dongle with HDMI support. Turn on both devices and connect them using an HDMI cable. Then select the correct HDMI input on your TV with the help of the remote control, and you’re good to go. Remember that some laptops have a micro HDMI or a mini HDMI port, so you’ll need a different cable — you can get it via the buttons below.
How to connect a laptop to a TV via HDMI:
- Connect the laptop to the TV with an HDMI cable.
- Turn on both devices.
- Select the correct HDMI input on the TV with the remote.
- Press the Windows and P keys simultaneously.
- Select Duplicate.
The connection between the two devices should be established automatically. But if it doesn’t, go to Settings > System > Display and make sure TV is selected. You can also adjust the resolution to match the one on your television.
How to connect a laptop to a TV with a VGA cable
If you have an older laptop and TV, you’ll likely find a VGA port on both. You can check out what a VGA cable looks like and buy one here. VGA isn’t as good as HDMI because of its lower-resolution video quality. It also only deals with the video signal, so you’ll need a separate cable to handle the audio.
Turn on your TV and laptop and connect them using VGA and 3.5mm audio cables. The next step is to press the Input button on your remote (which could also be called Source or AV) and select the PC or RGB option from the list. That’s it.
How to connect a laptop to a TV via VGA:
- Connect the laptop to the TV with a VGA cable.
- Connect the two devices with a 3.5mm audio cable.
- Turn on both devices.
- Select the PC or RGB input on the TV with the remote.
- Press the Windows and P keys simultaneously.
- Select Duplicate.
The connection between the two devices should be established automatically. But if it doesn’t, go to Settings > System > Display and make sure TV is selected. You can also adjust the resolution to match the one on your TV.
How to connect a laptop to a TV with USB-C
If your laptop has a USB-C port, you have a couple of options. You can connect it to your TV directly with a USB-C cable, but only if both devices have a USB-C port that supports video transfer. Just grab a USB-C cable, connect the two devices, and select the correct input on the TV. However, please note that not every USB-C port can carry a video signal. Additionally, the USB-C cable needs to be able to handle data transfers, so make sure to check all of that before buying a USB-C to USB-C cable.
The second option is to buy a USB-C to HDMI adapter.
How to connect laptop to a TV using USB-C:
- Connect the two devices with a USB-C cable. Alternatively, use a USB-C to HDMI adapter.
- Turn on the TV and laptop.
- Select the proper input on the TV with the remote, depending on the cable you used.
What if my laptop and TV have different ports?
Let’s say, for example, that your laptop only has an HDMI port, and your TV has an old VGA port. In this case, you’ll need an HDMI to VGA converter. They are relatively inexpensive.
Once you have the converter, the process is very straightforward. Also, remember that no audio will be transmitted, as VGA doesn’t send audio signals. You’ll have to use a separate audio cable.
How to connect laptop to TV using an HDMI to VGA converter:
- Plug the HDMI cable into your laptop.
- Plug the VGA cable into your TV.
- Plug the VGA cable into the converter to connect the two devices.
- Connect the two devices with a 3.5mm audio cable.
- Turn on the laptop and TV.
- Select the PC or RGB input on the TV with the remote.
- Press the Windows and P keys simultaneously.
- Select Duplicate.
The connection between the two devices should be established automatically. But if it doesn’t, go to Settings > System > Display and make sure TV is selected. You can also adjust the resolution to match the one on your TV.
Bonus tip: Use a USB flash drive
If all you want to do is check out your vacation photos or watch a movie on the big screen every now and then, you could use a USB flash drive — no need for cables or dedicated media streamers. Just transfer the content from your laptop to the USB, then plug the USB into your TV and select the USB input on your TV to play the files. But for this to work, your TV has to have a USB port, and it needs to support playing files locally, through the USB port.
How to use a flash drive to play media on a TV:
- Transfer images and videos from your laptop to a USB flash drive.
- Plug the USB flash drive into your TV.
- Select the USB input on your TV.
- Select the files you want to view and hit play.
FAQs

Yes. You can use either an HDMI cable or a VGA cable to stream your laptop’s screen to a TV. Additionally, you can use a USB-C cable alone, if both devices support the standard.
You can still use HDMI and VGA cables if you find an adapter or dongle.
Wireless connections are easier and more convenient. You can stream from any location as long as you’re within the same Wi-Fi network. That said, wireless connections are prone to some lag. An HDMI or USB-C cable will be better if you want more responsiveness, higher frames per second, and higher-quality imagery.
