For most of this month, one of the top 10 ranked Community Games on Major Nelson's list hasn't been a game at all, the TV Calibration app is a 200 point ($2.50) tool loaded with plenty of test patterns to make sure your video setup is configured perfectly. There's also a free trial, so we loaded it up and can say it does exactly what it says it does. Most games have at least some PQ optimization helpers, but it's unlikely you'll be able to get this detailed information about pixel mapping and test color patterns with a Gears of War
disc, and hey, you gotta make sure those Netflix streams look their best on your HDTV. Other calibration tools
may have a few more tests and work on more than one device, but for the price it seems to be a good value. Check out the gallery to see a few of the patterns included, or download it from the marketplace and give it a try.
