Yes and No. It entirely depends on what signal sources you use with your new display. Since it's a new set, I'm assuming that you are using it for HD (high definition), 1080i or 1080p, material. The GetGray calibration disc is designed for SD (standard definition) sources (SD-DVD players). If you will be playing SD-DVDs on your set, then the GetGray is very good. However, if you have a BD (Blu-ray Disc) player, and plan to play mostly BD discs, then the GetGray disc is not the best to use.
The grayscale (no color) is the same for both SD and HD signals (from DVDs), and any calibration disc will work to set the Brightness (Black Level) and Contrast (White Level) controls. However, the color matrix is different for SD (Rec. 601 specification) and BD (Rec. 709 specification) sources. Therefore, the color adjustments may not be the same, depending on how the SD GetGray disc gets translated from a 720 x 480i signal (on the disc) to a 1080p picture on your HDTV set.NOTE
: A calibration DVD (any of them) cannot be used to accurately calibrate your set for TV sources (cable, satellite, or OTA = Over The Air). Each source may have different settings for best picture. Most people (like me) use the same settings for TV as well, since it is usually fairly close to correct, and no two TV stations have the same quality signal anyway.IMHO, the best calibration discs are
(1) For SD-DVD players, GetGray
(the instructions are available on www.calibrate.tv)
- I prefer it for setting the grayscale;
(2) For BD (or HD-DVD) players, you have two "preferred" choices. The commercial choice is the "Digital Video Essentials HD Basics [Blu-Ray]
", which is available from Amazon, and other online sources. The second choice is the free "AVS HD 709
" disc: http://www.avsforum.com/avs-vb/showthread.php?t=948496
. Both of these have HD-DVD versions also, if you have a HD-DVD player, and not a Blu-Ray one.
Both the GetGray and AVS HD 709 discs require that you download the files, un-zip them, and burn your own disc (the free ImgBurn
software is the most trouble-free for burning either of these discs). Both use regular DVD writable discs (DVD-R or DVD+R) depending on what type of discs are compatible with your player. The "AVS HD 709" disc is only
playable on a BD player (it will not
work in a SD-DVD player). Also, for both of those discs, you need to get at least a blue filter (THX Optimizer Glasses (THX.com), or either the AVIA (Ovation Multimedia) or DVE color filters. Lee Filters also sells them too (Tokyo Blue = #071, Primary Red = #106, & Primary Green = #139).
As always, YMMV. While you can get fairly good results using a calibration disc and your eyeballs as the measurement instrument, using a colorimeter, or other measurement instrument, will get better results (for more money, of course).
If you are new to the concept of video calibration, I would highly recommend that you read the "Sticky Threads" at the top of this forum's main page. They will provide a lot of background into the calibration process and why you are doing calibration in the first place (no display is set correctly from the factory, and only a very few are even close).
