So, I won't be doing an extensive review... who am I kidding?!
[IMG class=inlineimg]/forum/images/smilies/eek.gif[/IMG] I have no time... work & family and all, ya know!
But, I just spent 3 solid hours testing 2D & 3D 1080p, and 4K HDR. And, comparing back-and-forth & side-by-side with my ceiling-mounted Optoma UHD51A. And, soliciting inputs from my wife & teenage kid (there's always an opinion there [IMG class=inlineimg]/forum/images/smilies/wink.gif[/IMG], LOL)... I now have a good sense of pros/cons to each PJ.

My screen, as I posted before, is a 100" Silver Ticket 1.1 gain white screen. In a decently light-controlled room (even with some ambient light), no special/expensive screen is necessary. The Xiaomi is plently bright.
I'm torn as to which PJ is better however, which to keep. I love the concept of these ultra short-throw PJ's. PQ is really bright (almost too much, definitely needing adjustment) & vibrant, frickin' sharp, with solid contrast & decent blacks (no better, no worse than my UHD51A on that last bit). Love being able to place on a shelf less than a foot away from a 100" screen. Both full 3D and full 4K are supported, on the Xiaomi I'm evaluating at least. On the other hand, I do see minor, but noticeable, jaggies in edges of objects, notably in [email protected]
content (like the Sony Camp [email protected]
HDR demo clip). I thankfully don't see artifacts with 4K film (23.976) material, but I haven't watched a movie yet for more than 15 minutes, only sampled scenes.
On PQ, color accuracy is better with Optoma UHD51A, with its preset Cinema setting. I also chose Movie mode with Xiaomi. Its color palette, with this setting, is warmer, with a bit of a red/orange push. All this can be adjusted, calibrated of course in User mode (and advanced picture controls
. With Optoma, when I evaluated the PQ side by side (with the Xiaomi), its color palette appeared a bit cooler, slightly blue-ish in comparison. The Xiaomi also has noticeable blown-out whites with all preset picture modes, so this should really be dialed down using HD & 4K calibration test patterns, which I do plan to do.

Oh, you need to enable HDMI 2.0 mode w/the Xiaomi to get 4K above 30Hz, and really for 4K HDR at any framerate for 4K HDR to look right. When playing HDR material, the PJ doesn't provide any visual notification (like the Optoma UHD51A does
that you're in HDR mode, or even what resolution is being rendered. You get a brief black screen, and if the colors have pop and look vibrant, you know you're getting HDR.
With 3D, I've already posted my impressions, but in a nutshell, it's a chore with this PJ. The better brightness (over Optoma UHD51A) helps with 3D, but enabling 3D isn't intuitive and takes a couple of steps, manually, to engage it. And, you have to manually disengage it. And, waiting about 15 seconds between mode changes to/from. But, the 3D quality is excellent. It's now apparent however that only certain 3D DLP-Link glasses work with this Xiaomi. These
, which I bought, and likely these
posted about, work. These DLP-Link glasses
I've owned for a couple of years, which do work perfectly w/Optoma UHD51A (and also worked with my previous BenQ HT2550 & 107x PJ's
do not work w/Xiaomi for some reason. So, we don't know the exact specs for which 3D DLP glasses do work w/the Xiaomi. My guess is they need to support the full range 96~144Hz synch.
So, I'm still unsure which PJ I'm keeping. I'm leaning toward the Xiaomi MIJIA, but the Optoma UHD51A remains an excellent 4K+3D PJ, and it's turning out to be a tough decision. The Xiaomi doesn't have the dark grey border issue that early TI .47 chip DLP's like it have. The main reason to keep the Optoma is color accuracy w/o any adjustments & seamless HD/3D/4K/HDR operation. The Xiaomi boasts better brightness, contrast, sharpness & short-throw placement ease.
