Calibrating the colour on your TV
February 1, 2009
Written by Rob Griffith
Doing what I do for a living can be a curse. I can’t flick through a magazine without looking at the quality of the repro and print, I can’t walk past an ad on the tube without peering closely at the dots. Needless to say local newspapers get recycled and not read due to the appalling quality of most of the images. It drives my wife nuts. Imagine my mutterings and chunterings when we had a new LCD TV delivered and the colour was a bit off. I was pausing DVDs and fiddling in the picture settings menus with the myriad of controls until I thought I had made an improvement. My wife put up with it for a day or so but my three year old son objected, loudly, to having Lightning McQueen’s adventures interrupted because his dad didn’t think he was quite the right hue of red. There was only one thing for it, the TV would have to be calibrated.
The Spyder3 TV uses the same colorimeter as the Spyder3 Elite or Pro systems but the big difference is that it comes with a DVD of test patterns that you play as you adjust the colours on the screen. You need a laptop close to the TV, of course. The software starts by asking you what type of TV you have (it will do them all, even projectors), and then what controls it has – Brightness, Contrast, Colour Temperature and Tint etc. You then have to show one of the test patterns, take a measurement with the colorimeter and then adjust the TV and measure again. There is a lot of juggling the remotes for your TV and DVD player and it took about 40 minutes but the improvement was considerable.
The only weakness is that my TV had more controls than the Spyder3 TV adjusted so I wasn’t sure what values to leave those that weren’t included at but opted to leave them at the defaults. The colour still wasn’t perfect but it was in the ball park and all I felt I needed to do was to adjust the red slightly to get the fleshtones a bit better.
I’d also like to know what standard I’m adjusting the TV to, presumably some TV industry standard. There is a professional level software from Datacolor called ColorFacts that is aimed at the broadcast industry and now I’ve dipped my toe into TV calibration I can see it as being a possible addition to our list of services.
