I posted this as a suggestion, that they place test cards on some channels late at night when stations go off the air or to place them on there filler channels like the Alt EPN channels when they are not on.
I've used the Avia and DVE to calibrate my DVD chain with good results. But Dish was alway different (different cable and connection).
Since different sources can have different DC levels and chroma and so on, the results weren't as convincing on dish. Since there's no way to get a test signal onto Dish, there's not anyway to get a reference from it.
Until last night. I happen to notice that HBO2 was showing "Sign Off", which is weird for HBO. I don't know that I've ever seen HBO "off-air". Checking the channel I noticed they were sending various tests down the line, notably an A/V Timing test. So I hit record and went to bed.I checked this morning and sure enough, there were test patterns in the recording. I got regular SMTPE color bars and then later the "split" color bars like on the DVE disk!
Did a little tweaking of controls while viewing through the color filter gels in the DVE package, so now the hue and saturation and brightness levels are well matched to what the DIsh produces. It was a fair bit different than what I got from the DVD player, as I expected. The sharpness settings did carry over well (way, way down from factory). Picture looks a little more accurate now.
Just an other way to perfect you Dish Picture quality- record the HBO off the air show. Then use the test patterns to tweak the TV.
