I’ll put my observations here as they fit. If you’d rather have picture quality discussion outside of the KB, feel free to move it.
Ran a quick round of measurements using both internal and external sources to get a better idea of why the picture looks the way it does.
First off, the good:
-
a big compliment to Prashant for fighting for an off-the-production-line calibration for us. It shows! Only being a hobbyist I don’t profile projectors every day, but I’ve seen a bunch in my time, and rarely have I measured one with RGB levels this close to target out of the box. Obviously they’re not all created equal, and that’s even more impressive. Mine is just a tad weak in the red across the range, bringing the color temperature up to just over 6600k. dE is below 2 across the spectrum. Good work, man! (internal and external)
-
Also, the corrections posted here leave brightness and contrast at just the right level for internal playback. (internal)
-
External is almost the same, with only minor clipping of the highlights. (external)
The not-so-good:
-
The primaries and secondaries (the colors) aren’t perfect, blue and green (and yellow as a consequence) in particular. Red is closer to target. I’ll look at the measurements some more tomorrow. Either way, I’m not expecting perfection here for a product of this price range, and as mentioned the levels are very good. (internal and external)
-
The gamma. This is the big one that ruins the subjective impression. Everyone who sees PPX is going to go “the picture looks flat”. It could look so much better! I ran the measurements a few times to make sure, but it really still is between a 1.6 and 1.7 average. No wonder it looks so washed out. (internal)
External gamma measured even lower, but it was only one round of measurements. Will do again to confirm. (external) -
Sharpness. Only an external source problem now. It’s bad. Thick halos everywhere, creating a harsh look, jagged edges and eating up fine detail. Needs an adjustable setting, a selection of “looks” or to be toned down to 0 globally. Internal is beautiful in comparison. (external)
I’m aware that a “looks” feature has been in beta for a while. I’d be glad to test it out when you get around to that application form I filled in. No sweat, though, it’s not going anywhere.
Cheers for all the hard work Prashant. Your passion adds immense value to this product.
