How To Connect Your Laptop to TV set

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) August 8, 2011 --

If you're like me, you have a lot of movies and music on your computer. You might sit in front of your laptop enjoying your media collection while you browse the Web and chat with friends. It works well, but when you have a huge 40+-inch HDTV and home-theater setup a few feet away, consuming your media on a 15-inch laptop screen with tinny integrated speakers seems silly. Wouldn't it be great if you could pipe what's on your laptop screen to your HDTV, and treat it just like another monitor? And wouldn't accessing your collection of movies and music through your HDTV be awesome? Well, you can do both of those things, relatively easily, in a variety of ways.

There are plenty of options for displaying your laptop on your HDTV. Many of them are excellent ways to watch your movies and listen to your music. Only some of them are appropriate for Web browsing, video conferencing, or other computer-reliant activities, however, and due to slight lag with current wireless display technologies, only a wired connection is suitable for playing most action-oriented PC-based games. Here are your options for connecting your laptop to your HDTV. First consider what you want to do, then choose the way that's right for you.

Best for Gaming: Run a CableMany recent notebooks offer built-in HDMI outputs, and those that don't, typically have DVI ports (which can connect to HDMI ports through an adapter) or VGA ports (which can connect to PC ports found on most HDTVs). If you don't mind being physically tethered to your screen by a length of cable, you can just plug it in and treat your TV like a second monitor. Since the HDMI/DVI/VGA connection can be video-only (a decreasingly common trend, but a possible one, especially if you use a DVI-to-HDMI adapter), you might need to use an audio patch cable to connect the notebook's audio to either the HDTV or a nearby set of speakers. Still, a direct, wired connection is the best method if you value speed over all else. With a cable, you're guaranteed zero latency between the notebook and the HDTV, making twitch gaming possible.

Pros: Lowest latency option. The only method suitable for fast-action gaming.Cons: Requires a physical cable, keeps you tethered to your HDTV. Might require a separate audio connection.

Convenient if Your Laptop Has It: WiDiIf you have a laptop manufactured in the last few years, it might already have Intel Wireless Display technology, or WiDi, built in. WiDi is a common feature for midrange and high-end laptops, especially ones that emphasize multimedia and home entertainment. Many of Best Buy's laptops include WiDi, offering 57 different models with the feature built-in. If it does, you can purchase a WiDi receiver like the $100 Netgear Push2TV HD, plug it into your HDTV, and wirelessly put your desktop on the big screen without even as much as a dongle. This system works very well for playing movies and browsing the Web on your HDTV, but slight latency keeps it from being ideal for fast-action games.

Pros: Wireless video and audio without plugging anything into your notebook. Supports 5.1-channel audio output. Cons: Not a standard feature in all laptops. Too laggy for fast-action gaming. WiDi 2 necessary for 5.1 audio support.

Simple Setup: Wireless HDMI connectors

If you have an HDMI port on your laptop and don't want to run a cable from the computer to your HDTV, you can still put that port to good use with a wireless HDMI kit, like the Vizio XWH200 Universal Wireless HD Video & Audio Kit, Asus WiCast, and Rocketfish 4-Port Wireless HD Kit. Wireless HDMI systems let you plug your notebook into an HDMI transmitter and your HDTV into an HDMI receiver, and have them act as if a single long cable ran between the two devices. Some kits, like the Rocketfish 4-port kit and the Vizio XWH200 kit, can double as HDMI switches, handling up to four HDMI devices at once and switching between them with a remote.

The main drawback to wireless HDMI devices, and wireless HDMI switches in particular, is that you still need to make the room and set up the transmitter just right. Multiple-port kits tend to be too large to keep close to the notebook, and are usually more suited for cabinets and racks where multiple pieces of home theater equipment might be sitting. Even the one-port WiCast has a power-hungry transmitter that requires either two free USB ports or an AC adapter, making it less than ideal for quick-and-simple connections between your laptop and HDTV. The audio and video quality are identical to running an HDMI cable, but, like all other wireless solutions, the potential for slight latency makes it less than ideal for twitch gaming.
