KEY FEATURES AND CONNECTIVITY OPTIONS
Convenience features, inputs and even the sound system are all factors to consider in your next TV purchase. Many TV makers differentiate their basic models from more expensive versions by including all kinds of add-ons, so check our list to help determine whether that swanky set you're considering really has the features that matter.

Picture-in-picture (PIP)
What it is: Found primarily on more expensive televisions, PIP lets you watch a second programme in a little window. More-elaborate versions can resize the window, move it around the screen, create still or multiple still images, or simply divide the screen into two same-size pictures, often called 'picture-outside-picture' (POP).
What it isn't: PIP has a dirty little secret, though: if you use an external tuner such as a Freeview box or a satellite receiver, you can watch only one programme at once.

Universal remote control
What it is: Plenty of TVs now come with universal remotes that can control other A/V gear. Usually, they work with a cable or satellite box, and many can also command DVD players, VCRs or even A/V receivers. If you like watching movies in the dark, you should look for a remote with backlit or glowing buttons.
What it isn't: Not every universal remote can control everything. Some, known as 'unibrand remotes', can control only the same brand of equipment as the TV itself. Most are preprogrammed with a set list of codes and if the codes don't match your older or off-brand gear, you're out of luck. A few are learning models that can accept the IR codes from your other remotes and, thus, control any kind of gear.

TV sound
What it is: Almost every TV sold today has stereo speakers, which provide much better sound than a single mono speaker. When TV makers list readings of 5 watts per channel or higher, it means the set has a respectable audio system for a TV. Some sets with simulated surround provide a semblance of the effect of rear speakers, although we find these models usually detract from the experience.
What it isn't: No TV can compete with a dedicated audio system, so even if your set has lots of watts and simulated surround sound, you should consider a home cinema audio system for maximum impact. If you have such a system, the TV's sound becomes a moot point.

Tuner extras
What it is: Channel-surfing modes, favourite-channel lists and other features that rely on your TV's built-in tuner can make switching channels a lot more efficient -- as long as you use that tuner.
What it isn't: The problem is, many people use external tuners such as a Freeview or satellite box to change channels. If you're one of those people, tuner extras are all but useless to you.

HDTV receivers and DVD players
A quick note about switching: if you have multiple sources going into your TV, an A/V receiver with switching capabilities can really ease the hassle. The most convenient option is to leave your TV set to one input and have the receiver switch all other sources into that input. Unfortunately, most receivers can't convert from, for example, composite to component video. Many receivers have regular component-video switching, though, which is a great feature if you have both a DVD player and are planning to buy an HDTV receiver.
