Good to know. Currently, my Roku Ultra is connected to my Vizio P-50 and it doesn't provide that level of information.

there are tradeoffs with everything. That being said I am coming around to your way of thinking and have changed my first preference to Epson 4000.

So I had TK800 for almost 2 weeks now. I have been touch by multiple issues:
- EDID sync issues causing no HDR output
- DLP link issues in 3d movies causing lost of sync
- 3d movies going into split mode (split line in the middle)
- long 20 sec 3d syncs
- whites over saturated to the point that "bold" subtitles were melting altogether.
- two "resets" of the unit.
- strange hissing going out of the projector.

I decided to pull a trigger on UHD51A as i am still in a month windows of return to amazon.
I have been watching content and playing games on my TK800 last night to "saturate" my eyes with the image.
I went thru GotG2 UHD, 3d , Thor Ragnarok UHD and 3d, some youtube movies and XBOX one HDR Assasin Creed Orgin.
Got annoyed by RBE on Assassin creed each time i used a map :-(

Now here comes UHD i mounted it underneath the TK800 went thru setting. Adjusted color, brightness etc..
I'm after whole day of using this projector.. and I am blown away...

- 3d took few sec to sync and automatically!!!!!
- 3d look much better then TK800 with better colors more depth etc.
- scences which de-syn in Life of Pi, not only did not do it but looked amazing on UHD51A.
- Thor Rangnarok coliseum fight and intial fight in UHD is something i will be re watching daily on this projector.
- Assasin Creen Orgins... omg... this flowers cannot be more blue and red... and ... and no RBE and purple tint when moving to map!!!

TK800 out, UHD51A found it's new home.

While true, this isn't one you should make in this instance. It would negate any advantages you'd get with trying to upgrade to 4K resolution. You'd be better off just getting a great 1080p projector with the right amount of lens shift needed.

The HC4000 is a great choice, but I think an even better one would be something like a JVC RS400/420/440, whichever you can get in the $2,000 range. They have the full 18Gbps HDMI input and as usual for JVC, better contrast and black levels.

Shoot me a PM if you have more detailed questions so we don't sidetrack this thread on the UHD51A. (Which I should be getting one Tuesday for evaluation and testing).

Agree we are well off topic and I am content to wait for a pretty stupid deal on the 4000 before pulling the trigger.

It hit $1500 last summer.

I encourage Optoma to keep reducing the input lag on models offering MEMC (which work at 4K resolution including with HDR content which this one apparently doesn't--yet), but if they expect people on AVS to be swayed by fluff like voice control to turn the projector on (a button on my remote suits me just fine, thanks, I prefer my electronics not listening and parsing everything I say in the privacy of my own home), then I have to laugh.

Work on contrast, light borders, laser light sources, input lag, and P3 gamut instead of things like Alexa. Please.

So far, Pure Motion has been available with all resolutions, color depths & SDR/HDR with the only exceptions being 3D and RGB.

Interesting and thanks for the feedback. I've noticed that light uniformity has been a long time issue with Benqs (and RBE). I didn't know it was that serious.

Has Benq dropped the quality control for pushing faux-4K too quickly?

Thanks for your input!

What about RBE overall on the UHD51A? I've always been sensitive to it, and it's my main reason to hesitate about a DLP projector. Has it bothered you on this one?

Only one review has been published and only a few people actually have a UHD51a in hand. You are going to have to wait a month or so before a reliable consensus is established.

So there is RBE on this projector in the different form then on the TK800. It looks for far it's less annoying but time will tell I only had it a day.
The worse part in TK800 was colorful scenes shifting to white, will see how it works here.

So far the biggest issues I have on UHD51A are:
- Reds are completely overblown
- brightness and contrast is definitely worse then TK800
- colors are so rich to the point of being unnatural

I'm trying to mount on siling permanently but I see there is some zoom problem.
At the same distance as TK800 i could it make smaller and fit my 100' screen with no issues.

On the UHD51A in the same mounting spot image goes beyond the screen slightly so i had to use -1 digital zoom and zoom in manually a little bit.

Is that correct ?

TK800 has
1.2:1

UHD51A
1.30:1

Anyone find a solution for Harmony remote? UHD51A isn't on Logitech's database yet. I did the remote teach method, but when powering on, it always goes to Media source, not HDMI1, where I need it. So, need to use Optoma remote to bring up menu and go to HDMI1; a bit of an annoyance.

I'm also finding the 3D image a bit dark coming from Epson 5040UB. (Non-issue, never mind). Need to play w/right settings (not just for 3D, but HD and 4K/HDR). 3D quality itself is very good; watched 'Black Panther' last night, and w/the shifting scope/IMAX aspect ratios, and 3D quality of the Blu-ray itself, it looked great.

Mine's added as an Optoma UHD550X. It works fine for power on and off, and starts up in HDMI1.

To Tuan or anyone w/nVidia Shield, are you getting 10 or 12-bit w/23.976 4K HDR content via Kodi? Whether I choose 'recommended' [email protected] or force another resolution, w/Kodi I always get 8-bit 4:2:2. However, with Zidoo X9S, I get 12-bit 4:4:4. Albeit w/minor sparklies occasionally, so may need a better 35ft 18Gbps HDMI cable.

With Shield, I do get 10-bit w/[email protected] HDR. Just doesn't seem to work w/23.976; only getting 8-bit. Not understanding why.

Check post #723 for mine. Basically I just use HDR and Cinema picture modes. I left pretty much everything default except for: Color (-24 HDR, 3 Cinema to reign in some blown out reds), Sharpness to 1 (still shimmering in fine details here and there) and Pure Motion Off (not for me personally). Dynamic Black was off by default and I left it off (projector fan noise is reduced somewhat with it on for sure though).

How do u feel about color... I don't understand how this calibrated if we have to go -24 !! to reduce this overblown reds and blues... That is kinda crazy.
I played the other day on -15 Injustice 2 with HellBoy and when i use his special where he jumps into hell i see only RED image with zero details... This is too much for my view.

I have similar experience with the reds being way too much and it takes a lot to reduce it. But overall the picture is quite nice.

I had one issue where the projector after hitting power down told me it would turn off in 43 seconds. I waited and it never turned off. Then the buttons on the remote no longer worked and a standard press of the power would not turn off. I had to hold the power button down for a bit so it would turn off. Not sure what happened there, guess could have been some kind of user error.


The always on light borders have been bugging me though. Still debating wether to keep this or go UHD65 since I can get it for not much more than I paid for the UHD51A.

From what I have read quite a bit better on color. I can also get it for a similar price. What has stopped me from getting it is at such a low price there is no return unless defective. Wish I could see it somewhere in person to compare.

I have seen many gliches so far:

- some sort of process showTV or something died and I was stuck on this main screen until I rebooted the projector.
- during the gamma changes image goes completely crazy and again some process was not responding and it stooped reacting to any image changes
- one time projector did not start

I think it's OS issues cause most of crashes came from android messages.

I really don't know what to think actually. The UHD60 and this projector both apparently have red and blue color in spades. I don't know why they are so jacked up out of the box. Maybe it's known somewhere that very saturated reds & blues make for a desirable image: if so, I'm not aware of it.
I personally wish I knew more about the advanced color settings and had some calibration equipment to really target just the range of reds (and to a lesser degree blues) that get blown out easily instead of using the more broad Color setting that affects all the colors.

With the UHD60 in HDR, I ended up with Color down to 0 (the default was around 19 or 23) and BrilliantColor down to 2 (out of 10). There was still color to spare.

Going from out of the box settings to color settings way down (far lower than I'd personally liked), the skin tones never looked bad or out of place; yellow and green never seemed to be affected much. Tint always looked good: felt no need to ever change it. Just saying all of that to say I don't have a complete enough picture of what's going on with the color processing to say ultimately what should be done. I just report here what I see and what limited things I know to do to improve them to my eyes based on other display devices and known source material (that I've watched many, many times before).

I use 2 YouTube 4K HDR (must use a Roku Ultra, Chromecast Ultra or something that can play them in HDR) videos that have reds in the over saturated range to adjust HDR Color and an app icon for SDR quickly. It's not the best but it's what I got and seems to work well so far across 2 projectors.

The first video (3 fabrics side-by-side: green, red and blue). With default Color setting, the red cloth will be solid red. At -24 you should start to see the details of the individual threads: blue to a lesser extent. That was as low as I wanted to go. It could have gone lower to see the thread detail properly.

The second video is good for all colors but I mainly just use the red and yellow portions. The first part of the video with reds is a good gauge of the results from changing settings in the first video. Even at -24 in HDR, there are lost details in the lighter red areas. In the yellow section of the video, many scenes will appear more yellow and less orange due to the lesser red.

All of that is with 10-bit 4:2:0. With 12-bit 4:2:0 from the Chromecast Ultra and all the same projector settings the same, all the details appear. Again, I don't have all the details of what's going on inside the projector as to why

For SDR, I just use the GiantBomb app icon (works for HDR also on the Apple 4K TV). There are 2 reds in the "Giant" text. If you cant see them both, reds are oversaturated still. With the settings I've mentioned above, they should both be visible (SDR to a lesser degree). Keep in mind I'm trying to balance keeping color saturation high, just not too high, and keeping both HDR and SDR in the same neighborhood visually.

Of course all of these are just steps to the ultimate goal. Now watch some actual content - various content.

Got to use what's at hand and that's quick. I've spent way too much time adjusting the UHD60 but at least I learned some shortcuts along the way.

Dynamic Black was off by default and I left it off (projector fan noise is reduced somewhat with it on for sure though).
How do u feel about color... I don't understand how this calibrated if we have to go -24 !! to reduce this overblown reds and blues... That is kinda crazy.
I played the other day on -15 Injustice 2 with HellBoy and when i use his special where he jumps into hell i see only RED image with zero details... This is too much for my view.

The light border is something alright. I'm getting "use to" but not liking it any more than before.

Just know that the UHD60 and I'm sure the UHD65 have light borders too just way smaller compared to the UHD51A. Someone in the UHD60 thread told me about it. I never saw it until I extended the image out beyond my screen. With the image normal size, the light border was 'ate up' by my screen's black felt border. With the UHD51A the light border extends 3 inches beyond the screen's 2-1/2 inch felt border. Using a 135" screen.
For reasons I haven't bothered to research, the active mirrors seem to need to be in the middle of a bed of mirrors surrounded by inactive mirrors. Can't terminate the active image edges abruptly? I have no clue.
I wish there was a way TI could apply a mask around the DMD over the inactive mirrors without corrupting the light output somehow. Optoma and other manufactures can't do it after the fact externally on account of lens shift, zoom, etc. affecting the image.

I had one issue where the projector after hitting power down told me it would turn off in 43 seconds. I waited and it never turned off. Then the buttons on the remote no longer worked and a standard press of the power would not turn off. I had to hold the power button down for a bit so it would turn off. Not sure what happened there, guess could have been some kind of user error.


The always on light borders have been bugging me though. Still debating wether to keep this or go UHD65 since I can get it for not much more than I paid for the UHD51A.

I'm also finding the 3D image a bit dark coming from Epson 5040UB. (Non-issue, never mind). Need to play w/right settings (not just for 3D, but HD and 4K/HDR). 3D quality itself is very good; watched 'Black Panther' last night, and w/the shifting scope/IMAX aspect ratios, and 3D quality of the Blu-ray itself, it looked great.

I use the settings for my previous HD142x. I had to add a 45 second delay between the UHD51A power on and the switch to HDMI 1.
The power on delay built into the My Harmony would not work. I had to modify the activity itself by adding a delay. Also My Harmony won't allow separating different commands for the same device.

i have packed up tk800 and staying with uhd51a.

i know i will miss the brightness, but this color .. even on -18 is unbeatable.

Can someone post a calibration details for this projector ?

Also i noticed that 3d does not have digital zoom anymore ;-( It means I will have to move 8-9 inches my mount to the front to not go beyond the borders of the screen.

Benq had better zoom options. This lens shift without keystone correction is something i don't like ;-(
