This is good, as I just bought a HD signal generator. lol.
Knew it would happen. ;-)
O.K., just checked and compared. Using the HBO pattern, they are oversaturated when compared to the signal that I'm getting with the Accupel signal generator. But if you notice, Voom or perhaps its their providers aren't very consistant with their signals. If you setup your color based on the HBO split color bars, you'll find that channel 100 and many others are under saturated. Solution for me was to setup my DVI input according to the HD signal generator (a little more saturated) and setup a component input according to the HBO pattern (a little less saturated). This is on a Sony GWIII. Depending on the channel, I can just go from one input to the other to get the best color. I made these adjustments in the service menu to color saturation offsets for each input as at the user menu level, one setting applies to all inputs.
As to how red and green saturations and hues compare, I noticed a slight difference between what the signal generator shows versus the HBO color bars. Keep in mind that when you're calibrating from Voom, you're getting the signal their provider is sending, and all the specific hardware inbetween. This should give you a better calibration, unless the channel doing the broadcasting isn't consistant with the other Voom channels.
By the way, the signal sent on 202 was at 1080i and the one on 204 was 480i.
