PC Advisor's comprehensive HDTV guide will show you how to set up your high-definition TV, from getting the best possible picture to making the right connections. Here's what to do once you get that brand new HDTV home.
Calibrate your picture
Calibration is the final step to getting the best possible picture from your new HDTV. Most new televisions come with picture "presets" - for specific inputs such as movies, games, and sport - that take the work out of adjusting contrast, brightness, hue, colour temperature, and sharpness. But the quality of these presets can vary.
Some manufacturers do a good job with them, and some don't, so test them before buying to make sure that they deliver the picture you want. TVs often emerge from the factory with their colour temperature and brightness set too high, or with their hues set too vivid, to give their picture a boost in a brightly lit showroom. If you want accurate colour reproduction customised to the lighting level in your viewing room, you should do your own calibration.
Quick and easy calibration
For a quick and easy "free" calibration, you can use almost any DVD that features THX audio. Star Wars director and THX developer George Lucas wanted viewers of his movies to enjoy accurate reproduction of both audio and video, so he provides a set of calibration tools in the DVD setup area of the disc. Just click THX Optimizer, and then follow the onscreen instructions.
Before you start calibrating, be sure to do three things:
- Adjust the room lighting to its level during the time when you'll typically be watching TV.
- Turn the set's sharpness down to normal.
- Make sure that the colour temperature is set to 6500 degrees Kelvin (the video standard).
When you're ready to calibrate, the THX Optimizer will lead you through five test patterns for adjusting contrast, brightness, color/tint, aspect ratio, and sharpness to their optimum levels.
The optimiser presents a simple instruction screen for each adjustment, telling you what to look for, and what parameters to alter. Do this while you are standing close enough to the screen to see any necessary detail.
