The computer is where many of us spend a good deal of our day working. It's also where students will likely be spending a lot of time taking classes for the foreseeable future. And it just so happens to be the ultimate media and gaming device, capable of playing more music, video, and games than any other platform. There's just one catch: Mostmonitors(and all laptop displays) are smaller than the average TV. So why not connect yourlaptopto yourTV for a far more compelling work and learning experience on a bigger screen?

You can, and there are several different ways to do it. Not every method is suitable for every situation, though. Depending on where your TV is, where your computer is, how your home is set up, and what media you plan to use your TV screen for, you need to consider exactly how to connect your laptop to your TV.

These techniques don't just work for laptops. If you have a desktop PC, you can connect it to your TV the same way. Of course, desktops are less portable, so if it's located far from your TV, it might not be as convenient or work quite as well.

Why Use Your TV as a Second Screen

If you're working from home, the biggest benefit to connecting your computer to your TV is being able to use it as a second monitor. TVs are bigger screens and generally farther away from your face than monitors, but you can easily toss a few Chrome tabs with Slack, your email client, and any useful information or messaging services up there so you can see if you need to respond to anything at a glance. Keep in mind a second-screen system only works with a few of the methods listed below, though.

This can be a big advantage for students, too. A large screen offers a bigger, clearer view of presentations and speakers, and allows for easier collaboration if a number of students are attending remote classes at once. If a laptop or tablet screen doesn't seem like it'll be big enough for schoolwork, a TV will do the job.

All of these methods let you stream media to your TV, so if you have lots of videos on your hard drive or only visible through a web app you can send them to your TV. You can also use Plex to simply share your entire local media library, along with a slew of online services, directly to your TV with a simple menu interface.

You can even game this way. An HDMI cable is the best way to do this locally, but Steam Link has proven surprisingly capable of streaming locally networked gaming from your PC to your TV.

HDMI: Connecting With a Cable

This is the most direct and reliable way to hook up your laptop to your TV. It's also the most limited by your home layout. It's a simple solution: Run a physicalHDMI cablebetween your computer and your TV and you'll get the best performance and reliability. A wired connection means the best picture quality and lowest input lag, and it won't be affected by the wireless network environment around your home. It's what I use in my apartment, and it lets me play PC games on my TV. In fact, the low lag of a wired connection makes this one of the few acceptable ways to play PC games on your TV (though Steam Link has certainly proven its worth on that front, especially if you can connect it to your network over Ethernet). It also supports 4K resolution, if your laptop can handle it in the first place.

Then again, my apartment isn't huge, so using an HDMI cable is easy. If you keep your computer in a separate room, running a cable isn't the most convenient or realistic solution. If you don't mind a little construction, you can build conduits between rooms and keep a cable in-wall to avoid clutter, but that isn't feasible for everyone (especially renters). There's also the distinct limitation of range. At best, you can run 50 feet of HDMI cable before losing signal quality. More realistically, you might seem some hiccups in the picture if you go past 25 feet. There are HDMI amps that can extend the reach of your cables, but that adds more cost and complication to the setup.

If you decide to go this route, make sure to read our explainer onWhat You Need to Know About HDMI Cables.(Hint: Cheap ones work just fine.)

Pros:Best picture quality and input lag. Most reliable connection. Supports 4K. Arguably the only method really suitable for gaming.

Cons:Physical wires can be a pain to run between rooms or across long distances. Limited range without additional equipment to boost the signal.

Cable-Free Cables: Wireless HDMI

If running a physical cable between your laptop and your TV isn't realistic, but you don't want to deal with streaming software, you use a wireless HDMI extender. Wireless HDMI extenders send HDMI data wirelessly between a transmitter and receiver, letting you simply connect your laptop to a nearby small box with a short HDMI cable, and your TV to another nearby small box with another nearby HDMI cable. With the paired extender devices powered and connected, they work just like an HDMI cable. Many have better range than HDMI cables alone, reaching up to 100 feet, and since they're point-to-point they won't be affected by traffic on your home wireless network.

The wireless connection requires some compromises, though. First, most wireless HDMI extenders top out at 1080p, so you can forget about streaming 4K HDR video directly through them. Second, they tend to be pricey, running from around $130 to over $200. Third, they tend to show significant video lag. It won't be an issue if you're just watching video, but it can make playing PC games feel very awkward.

Pros:The same easy, direct connection as HDMI cables. Longer range without physically running cables. Doesn't rely on your home network.

Cons:Doesn't usually support 4K. Too much lag for games.

Chrome-Friendly Streaming: Chromecast and Google Cast

If you mostly want to send streaming movies and TV shows from your laptop to your TV, theGoogle Chromecastis an easy way to do it wirelessly. Just plug it into the back of your TV and connect it to your network. You'll be able to stream any Chrome tab from your notebook to it with the click of a button. That means Netflix, Hulu, and almost every other majorstreaming service. It also means any YouTube video, animated gif, interesting web page, or any other content you can load in Chrome.

If that isn't compelling enough, it's very inexpensive for a physical device, with the 1080p Chromecast available for $35 and the 4K-capableChromecast Ultrafor $69. If you have an Android TV, Google Cast is built in and you can stream directly to it already.

Chromecast is very functional for computers, but it's more designed for mobile devices that support Google Cast. If you have anAndroid phoneor aChromebook, you can stream the device's full screen to a Chromecast directly without going through a Chrome tab. A wide variety of streaming apps also feature Google Cast support, so you can stream media from those apps to the Chromecast and use your phone as a remote. PC control is a bit more limited, focused mostly around the Chrome web browser as a front-end.

Pros:Inexpensive. Streams video or web browser tabs. Chromecast Ultra and some Android TV devices support 4K.

Cons:PC integration and support are limited compared with Android devices.

Wireless Windows Standard: Miracast

Intel's WiDi wireless display technology has been discontinued, but Miracast carries on the torch, and it's natively supported in both Windows 10 and Windows 8.1. Just click on the notification button in the system tray, expand the buttons on the menu that pops up, and click Connect. You'll be able to mirror your screen directly to any Miracast-compatible device on your network. That includes many smart TVs and media streamers. You can also get a dedicated Miracast receiver and plug it into your TV (Microsoft makes an official receiver for $50 called theMicrosoft Wireless Display Adapter, which will almost certainly work with your modern Windows PC). With your PC connected, the screen will show up on your TV through its Miracast-compatible screen streaming mode, or Miracast receiver.

It's a more economical solution than using a wireless HDMI extender, and depending on your TV's smart platform, you might already be able to use it. Like the extender, though, video resolution usually tops out at 1080p. If you have a higher-resolution monitor, the screen will probably be scaled down as it's transmitted to the TV or adapter. Like most wireless solutions, it can also suffer from display lag, which will hurt playing games over it.

Pros:Natively supported by Windows 8.1 and Windows 10, and some smart TV platformers. Receivers are relatively inexpensive.

Cons:Doesn't usually support 4K. Too much lag for games.

Big Laptop Libraries: Plex

If you've built a big media library on your computer, you can stream it easily to your TV usingPlex. Plex is media server software that can catalog all of your video and audio files and stream them to any device running the Plex app. It can also act as a front-end for streaming media services, and can even record live TV with a USB tuner.

All majormedia streamerssupport Plex, along with many smart TV platforms. It can even stream to your phone, tablet, or any other compatible device outside of your house, as long as your computer is on and connected to the internet. Plex is available for free, but for more advanced features like live TV and DVR, you need to get the premium Plex Pass for $4.99 a month, $39.99 a year, or $119.99 for a lifetime subscription.

Plex is very functional for media playback and streaming, even in its free form. It doesn't support any sort of screen mirroring, however; anything streamed to the Plex app on your TV or media streamer must be registered through the server software. That means no games. It also tops out at 1080p, so it can't stream 4K.

Pros:Robust media format and service support. Accessible outside of the home. Free, with optional premium subscription for advanced features.

Cons:Doesn't support 4K. Doesn't work with games.

Just For Games: Steam Link

Valve released theSteam Linka few years ago, and while it didn't make many waves, we were impressed by its performance. It was a media streamer designed specifically for PC games. You connected it to your TV, paired a controller with it, and you could play games on your computer through it. Your PC handled all of the graphical processing, and the Steam Link managed the audio/video and input data. It was surprisingly responsive if you had a very good wireless connection, or even better, could connect at least one of the two devices in the chain to your router over Ethernet.

The Steam Link as a device has been discontinued, but Valve has released apps that do the same job with software on a variety of devices. You can installSteam Linkon Android TVs, Apple TVs, and Samsung TVs, or even on a Raspberry Pi if you want to build your own Steam Link box.

Steam Link is specifically designed for games, so you're not going to be able to do much general media streaming or screen mirroring with it. In fact, since it depends on Steam's Big Picture mode for an interface, you can't actually access any content not directly available on Steam. It isn't a solution if you just want to watch movies and TV shows (though some movies, likeJohn Wick, are available on Steam and can be watched through Steam Link). You can work through your PC's desktop by minimizing Big Picture mode through Steam Link, but it's an awkward, unreliable solution.

Pros:Low latency for PC gaming.

Cons:Not suitable for streaming non-PC game content.

Which Solution Is Right for You?

All of these methods are useful in different situations. I like the old-fashioned HDMI cable as the best short-range solution. If you can't run a cable, Google Cast and Plex are excellent options for streaming media, while the Steam Link is great for gaming. You have plenty of options, depending on how you want to use your TV.

And if you want a second screen but are looking for something smaller than your TV, our guide tousing your iPad as an extension of your computercan get you started.
