We change and improve our testing and scoring procedure on an annual basis, so TVs tested in different years may not be directly comparable
Type of TV
LED TVs are actually LCD TVs but with one crucial difference - the screen is illuminated by hundreds of tiny LED lights rather than a handful of traditional lamps. This allows them to be slimmer and display brighter, sharper pictures than LCD TVs. Plasma TVs use different technology to LCD and LED, and they can display more detail in the black areas on screen. However, they're also hungrier on the power.
The type of digital tuner(s) that the TV has, plus whether they're standard-definition or high-definition. Some TVs have both Freeview HD and Freesat HD tuners, giving plenty of options for watching content without a subscription.
Screen size (inches)
This is the size of the screen in inches, measured diagonally across.
HD ready 1080p
All TVs we review are 'HD-ready' and so are suitable for watching 1080i HD TV broadcasts, such as on Sky HD or Freeview HD. The 'HD-ready 1080p' logo means the TV has a 1,080 line screen resolution, and can handle HD TV, but also the higher quality 1080p signal used on Blu-ray movies. These TVs, also referred to as 'Full HD', cost a bit more than HD-ready ones, but you usually get better overall HD picture quality.
Native resolution (pixels)
The number of pixels the TV can display (horizontal x vertical).
Allows you to plug a hard disk drive into the USB port to pause, rewind and record live TV via the built-in PVR.
The TV is capable of displaying 3D TV from Sky, as well as 3D Blu-ray movies. 3D glasses are sometimes sold separately - check the reviews for this.
Allows you to access a selection of internet 'apps' and web content, such as catch-up TV and movie download services like BBC iPlayer and Netflix. Some smart TVs allow full web browsing.
Access to an online app store allowing you to download more apps to your TV.
Smart TVs often come with a number of pre-loaded apps. Manufacturers can add new apps or take ones away, but this is the number of pre-loaded services at the time of testing.
Allows you to surf websites on your TV.
Some smart TVs come with built-in wi-fi, while others connect wirelessly with the addition of a wi-fi USB dongle (either supplied or sold seperately).
Sockets for connecting up high-definition equipment, such as a Blu-ray player, games console or Sky HD box. HMDI carries HD video and multi-channel audio.
Independent picture settings
Allows you to set and save different picture settings for different inputs (for instance Scart and HDMI) on your TV. Useful if you've fine tuned your picture to different settings, for watching DVDs or a Sky HD box, for example.
Means you can plug in your digital camera and view photos on the big screen (they tend to look great on high resolution displays). Many USB ports support digital music and camcorder playback.
SD card slot
Means you can view photos from various digital camera memory cards on the big screen.
Socket for plugging in headphones.
Headphone volume control
The most versatile headphone outputs allow you to control headphone volume independently from the main speakers. Useful if you're hard of hearing.
This means the TV can decode an audio description signal. AD is an additional narration for visually-impaired people that describes significant visual information, such as body language and scenery.
Boosts dialogue over background noise and music
Based on using our viewing panel's ideal picture settings. Settings are aimed at getting the best picture, but typically mean it uses less energy too. An energy efficient 40-inch LED should use around 60-70 watts. Larger 42-inch plasma TVs will use more than twice that amount of energy.
Eco mode (Watts)
Energy consumed with energy saving picture setting activated (typically involves dimming the backlight).
During standby after 2 hours and/or using ECO mode. Ideally this should be below 2 watts to meet the Energy Saving Trust recommendation.
Annual running cost (nearest £).
Based on the TV switched on for 5 hours a day and left in standby for the rest of the day. Electricity priced at 14.5p per kWh.

As rated by our independent expert viewing panel when watching Freeview broadcasts. We capture a stream of programming and watch the same clips in each test.
As rated by our independent expert viewing panel when watching a standard definition programme recorded on a HD PVR 'up-scaled' by the TV into pseudo HD. The Box output is connected to the TV via HDMI and we watch the same clips in each test.
Overall SD picture
Overall combined score of Scart RGB and Freeview.
Freeview HD picture

As rated by our independent expert viewing panel when watching Blu-ray (1080p) clips, including movies and documentaries.
Overall picture quality
An overall picture quality rating by our independent expert viewing panel across all the video clips they use for testing TVs.
Overall HD picture
Combined score of Blu-ray and HD TV tests.
Rated by independent expert panel watching a series of 3D Blu-ray and Sky 3D clips. We watch the same clips in each test.
A rating of the picture quality of a TV when it is viewed on an angle.
Based on our technical tests and independent listening panel's verdict.
A rating of the performance of catch up TV services, such as BBC iPlayer.
Overall ease of use
Overall rating for ease of setting up the TV, everyday ease of use, using the instruction manual and EPG, operation without the remote control and accessing the more complex functions.
Assessment of the Electronic Programme Guide.
Using the smart TV functions - setting-up, downloading and organising apps and browsing the web.
Using the built-in PVR or USB recording device, if the TV has one.
Using the smart TV web browser.
Overall energy use
Based on the power usage when thr TV is on and in standby, along with the presence and effectiveness of power-saving features or 'eco modes'. Power usage can vary massively depending on the type of TV - a 42-inch plasma TV uses about twice as much power as similar sized LED TV.
Overall rating for number, functionality and versatility of features.
