Color decoding is not great and overscan can be severe. All these can be fixed with a Lumagen and the result is unbelievable.
Actually the Mits HDreadys have always had a grid in the advanced User conv section, capable of tightening up the red and blue against the green. All else being optimized already, it CAN be used for supertight picture, and keeping it that way after a professional grade calibration.
Unfortunately, since green is not available to the user, even with that advanced grid and point sys available to the owner, geometry stays as it was left at the factory - atrociously overscanned, as Glen said, and possibly wonky as well.
And the grid is way too hot - too high a light level - and too thick to get it really tight, like you can in sm, where you can send in your own mid-light level, thin grid to use instead. It also doesn't allow for going outside the visible realm of the screen to work with points out there, to get the visible points better, like the sm point sys does.
I'm sure a Lumagen is all that Glen says it is - haven't tried one - but keep in mind that the basics still have to be covered before going to that level. It can't compensate for poor focusing, nor poor geometry nor poor convergence - correct me if I'm wrong, Glen, I have never see a scaler/processor that does geometry and convergence as well as the other things it excels at - which are mainstays in CRT tech. Especially after reducing overscan. I believe you have to do all of those within the display itself.
On OOB units I usually find 2 of the 3 lenses out of mechanical focus, a heavy duty amount of misconvergence even after the first 100 hours - which we call the drift period - and of course a very pink grayscale, almost every time on Mits's, in their undying dedication to the color RED.
Red push, pink grayscales, etc...
The L will take care of the grayscale, and will make getting the color correct INFINITELY easier than PerfectColor will - and is probably worth its weight in gold for these things, esp. if your unit is before they had PerfectColor in User section.
But keep it in its place. The basics have to be covered first.
Glen - thanks for the tip on how to pause the 622 DVR's image! I can now take screenshots from fully fixed pauses, without having to deal with that infuriating slo-mo, nor any fixed pause bars or symbols of any kind!
Just the pure picture, in all its glory -
