Thought I'd post a part II to my initial review earlier
. Just spent another 3 hours w/the Xiaomi, really critically evaluating PQ, picture options/controls and whether motion artifacts/jaggies are bothersome enough for me. Trying to finally decide whether to keep this PJ, with the flaws I & others have pointed out, or stick w/my Optoma UHD51A for a while (until a better UST PJ that's 4K+3D capable comes out).
Re-positioned/re-setup the Xiaomi PJ again, trying to line it up as best possible, even & all, with my screen. Because my screen has beveled edges/black borders (pic
), no matter what, with the Xiaomi projecting up toward it, part of the bottom of the screen gets cut off (like so
). You really need a screen w/a flat or flat-ish border with this PJ.
For testing, plugged in my Zidoo Z9S to HDMI1, and nVidia Shield TV to HDMI2 (pic1
). Was hoping the picture mode settings could at least be uniquely saved for each input... and yes, thankfully so! For each input, to get around picture settings being the same w/this PJ, no matter 3D, 1080p, 4K SDR & HDR, you at least can have a secondary picture setting for input 2, and another for input 3. But, the pain is that when running source devices though an AVR, like most of us do, there's only one HDMI out to the Xiaomi. Unless, that is, you introduce a HDMI switcher in between, which may cause HDMI handshake issues as the Xiaomi is so picky/sensitive with HDMI cables & getting HDMI 2.0/full [email protected]
Before I talk about picture settings & PQ, someone earlier asked about distance between screen & PJ. This is w/my 100" screen: pic1
Oh, think I mentioned it before, but the Xiaomi is rather finnicky going into HDMI 2.0 mode. Even if it works once, and you come back another time/day, don't expect it to work, as you may need to unplug the HDMI cable & plug it back in, or turn off the source device & back on. This shows
when I powered on for the day, and this
after I unplugged/re-plugged the HDMI cable.
The best thing about the Xiaomi PJ (other than it being an UST) is its sharpness and uniformity
(better than 90% or better over the full projected image). Both of these aspects are better than two 4K DLP's I've tried so far (BenQ HT2550 and my current Optoma UHD51A).
So, finally, picture settings & trying to get as accurate colors as possible. I'm eyeballing it as I don't have professional calibration gear. But, this is the toughest part w/the Xiaomi, trying to dial in what looks right as none of the presets really (or fully satisfactorily) do. And, as I mentioned, once you get colors right for 3D source, they just don't look right for SD/SDR, and yet not again for 4K HDR. And, with each input on this PJ, you're stuck with only a single set of image settings, which sucks. So, here's me trying to work picture w/3D (pics taken via iPhone with 3D glasses in between):
- Picture setting1
(in actual viewing, doesn't look as red)
- Picture setting2
(actual looks warmer, more orange/yellow)
- Picture setting3
(actual looks pretty good, but picture goes softer)
- User setting1
(@mlkconcept's settings, while look good in this iPhone pic, actually look a little drab/washed out, but definitely more accurate than all of the above)
- User setting2
(my 1st custom, trial & error, in actual viewing, looks right-ish)
- User setting3
(my 2nd custom attempt, in actual viewing, also looks right-ish)
- User setting4
(my 3nd custom attempt, in actual viewing, looks more right)
- User setting5
(my 4nd custom attempt, in actual viewing, also looks right)
Before I leave 3D, wanted to mention that I tried several full 3D, SBS and HOU titles, and all worked well, in rendering as proper 3D. The 3D effect is excellent across the board, depth, no crosstalk or ghosting, brightness. Initially had thought 3D was better than BenQ’s & Optoma’s, but it isn’t; rather it’s the Xiaomi’s sharpness that makes it seem so.
So, moving on to a different input (HDMI2), I get to apply this input's own/unique picture settings. Now I'm using nVidia Shield TV, and trying a demo 4K HDR clip. When I replicate/apply that last custom picture setting from 3D from input1, it looks like crap. See what I mean?!
So, proving my point, the same picture settings will not work across SD/SDR, HD, 3D & 4K HDR. Now, the sample looks much better with both the standard preset
& movie preset
(and minor adjustments can make this better), which wasn't the same w/3D source.
And, when HDMI 2.0 mode locks in, you can see here
that the Xiaomi PJ supports [email protected]
/REC2020/10bit just fine (as indicated by my nVidia Shield).
Finally, I tested several FPS/motion test clips, and the Xiaomi doesn't fare too well. I'm seeing motion judder in 1080p or upscaled to 4K. It isn't as bad in 4K, but still noticeable. I then tried a couple of 1080p and 4K movies with camera pans, and the judder is noticeable. Not as severe like with test clips, but noticeable & bothersome nonetheless. Add the jaggies I also notice with 60fps content, both 1080p and 4K, and all these issues add up to pretty significant dings for home theater & movie enthusiasts.
So, where do I stand w/the Xiaomi PJ vs. Optoma UHD51A? After this second round of critical testing, I'm thinking of sticking w/my Optoma UHD51A. I really wanted to like (no, love) the Xiaomi UST, but it's hard to ignore all the flaws. Not one is a dealbreaker, but considering all of them, I'm afraid it is. In the end, if I compare these two PJ's based on PQ, not the coolness of the Xiaomi being a UST, the Optoma is just better all-around. Sure, the Xiaomi is sharper, brighter & punchier, but its picture is also blown-out, where you miss highlights & details. And color accuracy isn't that good, where Optoma easily bests it. Not to mention, the Optoma also does automatic 3D switching, proper 23.976/24 and no video artifacts, and cinema picture settings that look good no matter which source or type of content.
I'm going to play around some more w/the Xiaomi over the weekend before making a final call on it. But, I don't see most of its flaws as really addressable. Firmware updates may help, but as I rewatch Vincent's YouTube review of this PJ & read Secrets' review of the Vava
(basically the same PJ), I get the sense we need to wait for these APLD UST's to mature some.
