The ABCs of HD TVs: Television Buyer's Guide

Of all the sectors within the consumer electronics market at the moment, perhaps the fastest moving one is that concerning TVs. Television manufacturers are constantly reworking their products to create a constant stream of updates and new models, each with more features than the last. It can sometimes be tough to keep up with all that terminology, so hopefully we can help with our tech-talk busting guide to HD TVs.

1080p - You've probably seen this bandied about quite a bit. It is often referred to as full HD. This refers to TVs capable of displaying a resolution of 1920 x 1080 pixels in progressive scan mode.

FPS - Stands for Frames Per Second and refers to the number of times the image on the screen is refreshed over a one second time period. Traditional TVs ran at 24FPS, while most regular HDTVs run at 50 or 60FPS. Newer models now run at 200FPS and higher, mainly due to their ability to show 3D content.

Contrast Ratio - This is the difference between the darkest black and whitest white possible to be displayed on the screen. It is often the case that the best way to see the real quality of a HDTV is to see how dark the blacks are in comparison to the brightest whites. The problem with this figure is that there is no industry standard measurement, meaning that manufacturers can "massage" the numbers to suit themselves.

DLNA - Stands for Digital Local Network Alliance. A TV featuring DLNA compatibility will have the ability to access information, such as images or movies, via your home network.

HDMI - If you've got a HDTV then you really should be connecting devices to it using HDMI where possible. It's the best quality connection available for high definition sets - so make sure when you're buying a new TV that it's got enough HDMI ports for your set up!
