I recently purchased a plasma for my secondary viewing area, I only have a 480p dvd player connected and I was going to try and calibrate the grayscale with my I1 display Lt. I have Video Essentials and an early version of Digital Video Essentials HD DVD combo disc, but I can't seem to find the 0 - 100 IRE 10% step patterns.
Am I missing where the patterns are located? If not is there a SD disc or download with the proper patterns?
thanks

DVE SD does not have 10 step grayscale.
DVE pro does. (+$200)
So you are not missing anything ... it just isn't there.

you can buy GetGray here:

it has the IRE 0 - 100 for you to do your tweaking.

What you should have said is that it covers Digital 1 to Digital 254 (Digital 0 and Digital 255 are reserved for control flags). Digital 16 = 0% Stimulus = Video Black, and Digital 235 = 100% Stimulus = Video White. For CRTs, Video Black = 7.5 IRE and Video White = 100 IRE. However, the term IRE is not applicable to digital video signals and flat panel, fixed pixel, displays. Appendix B of the GetGray Readme file has a table showing the relation between IRE and the Digital signal levels and % Stimulus (0% = Digital 16 = video black, and 100% = digital 235 = video white).
NOTE: HCFR has the tendency to use IRE and % Stimulus interchangeably and those two values are not equivalent. Video Black = 7.5IRE = 0% stimulus. The IRE scale is offset by this amount. However 100 IRE = 100% Stimulus.
byeloe -- Yes the GetGray disc has both 10% Step patterns and 5% Step patterns. On the www.calibrate.tv page (~3/4 of the way down) is the "instructions" = GetGrayCalDiscReadme.pdf file. Download this (it's free) and read it. If it has all of the test patterns you need (it should), then you definitely should consider getting it. I found that it is the easiest calibration software that you can have. It is also the most accurate (and equal to the Pro version of either AVIA or DVE, for a whole lot less money).
It does require that you have a DVD burner and IMGburn is the recommended DVD writing software (although any software, that can write an ".iso" image disc, can be used). Since you have DVE, you can use the same filters for the GetGray disc.
BTW, the DVE blue filter actually works better for plasma displays, since it also filters out UV which can be emitted by some plasma TV models.
Many use Getgray and it is highly recommended....
