Here's some first impressions and a few quick measurements:


I'm pleasantly surprised with the Optoma UHD65 so far. The one aspect I'd say that I wanted to see most on this unit was how well XPR (e-shift) performs. Now, while there are some slight oddities with single pixel test patterns (I took a quick look at the R.Masciola UHD test patterns), in practice it looks exceedingly similar to that of a good single chip .65" DLP projector in terms of pixel sharpness. Text looks how it should and about as good as I've seen it look with Sony's native 4K projectors. I guess what I'm trying to say is that if you didn't know this was an eshift unit, you'd actually think this projector had a native 4K image (until you looked close with some test patterns). That was a surprise. I was expecting text to look a bit more wonky, like how JVC's eshift units look, but it doesn't. I use an HTPC most of the time to feed video to my projectors and from my seated position text sure as hell looks like it's coming from a native 4K projector. The lens used in this projector is "good" for it's price, but it can't delineate pixels anywhere near as well as the better .95" DLP 1080p projectors, but again, it's hard to see that slight sharpness deficit from the seat, plus you gain literally 4 times the amount of pixels on screen, so there's absolutely no doubt in my mind that this projector will look considerably sharper than the best high end single (and 3-chip) 1080p DLP projectors out there if you were to compare a good quality 4K source on this projector versus the 1080p version of that same film on those 1080p projectors.

Here comes the contrast numbers. It will come to no surprise to many of you to hear that it isn't as good as most of the .95" DC3 and DC4 1080p projectors that came out about a decade ago. This is a shame but a lot of this comes down to physics. The size of the mirrors on these DLP DMDs make a big difference to contrast potential. The mirrors on those DC3/DC4 1080p DMP DMDs were simply a lot larger so they had the potential for more contrast than the mirrors found on this .67" DMD. At max zoom on the lens (so worst case scenario for on/off contrast) and in high lamp mode, I'm measuring 1456:1 native contrast and with the lamp dimming based "Dynamic Black" engaged we do see a considerable jump in contrast to a decent 5394:1 dynamic contrast. That's a nice ~3.5x increase in contrast performance. I should also note that Dynamic Black engaged hasn't really given me too many issues in it's "visibility". You can definitely leave this engaged without it being bothersome. That's a nice plus I also wasn't expecting. But I also haven't spent enough time with this unit to say how well it enhances contrast with actual content. What I mean is, I haven't spent enough time to see if there's a decent increase in contrast when real content is being displayed and if most of this ~3.5x increase is only for when a 100% all black image is on screen. Contrast performance is subjectively a lot better than I thought it was going to be from what I've seen so far and I think that is a good indication that contrast is being enhanced a decent amount with real content on screen.

Brightness performance from what I've measured out of the box is extremely close to Projector Central's review. See here for those numbers. Reference Mode has the most accurate color out of the box and unfortunately this mode doesn't put out a "competitive' amount of lumens when we look at some of the other HDR compatible projectors like the similarly priced Epson 5040 and current JVCs and Sony 4K models. I'm measuring 850 lumens in high lamp mode and I'm sure this is going to go down a bit to further to pull in the white balance and color closer to D6500 and REC709. For most people this will be fine when it comes to SDR content, but unless you have a particularly small screen, HDR might not look at it's best on this unit. With that said, I haven't looked at any HDR content yet so maybe I'm wrong here.

Some other odds and ends. I measured input input lag with the Leo Bodnar lag tester at 75ms. But this isn't a 1080p native projector and the Leo Bodnar device only outputs 1080p so if you're feeding the projector a UHD or 4K image it will more than likely have a different amount of lag. Anything 1080p sent to this projector, however, will have about 75ms of input lag. I'd also like to comment and say that RBE (rainbows) are hardly an issue. Considering the brightness, I'm surprised I haven't seen more of them. This is also the quietest DLP projector I've had here. It's as quite as a current JVC projector in low lamp mode and has the potential to put out about as much light as a JVC in it's low lamp mode. Kudos to Optoma for this achievement. I was beginning to think all DLP projectors were doomed to be loud.

These are just some quick thoughts and measurements. I hope you find it helpful. I'll be spending some more time later with this projector to see how HDR looks. I'm honestly surprised a bit at how good overall this projector performs. It definitely took me for surprise.

Great info, thanks for taking the time to post first thoughts.

850 in high lamp seems pretty low, is it close to D65/R709 @ that measurement?

I can't go back to an 850 lumen projector.

I'm going to try and calibrate this unit tomorrow, but I have some family things going on so it might have to wait until Sunday night. Unfortunately, I think this is par for the course with this unit. Projector Central was measuring in right around the same amount on their review sample.

This has been very helpful Seegs, thank you....

Regarding blacks, what are your thoughts if one is only upscaling only BDs with madvr to 4K?
What about a fade to black with the auto iris engaged, does it work ok?
Did you ever see any of the usual flicker/pumping of the iris in testing dark scenes?
Ive never been able to use the feature as I hate the artefacts they all seem to introduce from time to time....

this is the info they posted, it sound like the production is similar to their pre-release.

curious to hear how HDR looks with this lumen output & R709 vs. the JVC



please post the PC text when you get a chance, thanks!

Nice first look Seegs.

Could you do me a favor and let me know how loud the projector sounds in High Altitude mode for low and high lamp settings?

I also didn't really say much about the negatives that I've witnessed so far. The menu system isn't particularly intuitive and (like most other projectors) there's too much crap enabled by default out of the box that do more harm than good to the image. I feel that most newbies with not realize that most of these settings should be turned off or down considerably. All the "Pure" crap is turned on by default and you need to go into like 3 different sub-menus to disable them; PureMotion, PureContrast and PureColor. "Ultra Detail" is also engaged and shouldn't be. Too much edge enhancement for my taste and I also don't like how they handle the regular "Sharpness" setting. '0' should be the default setting that best represents a neutral position. The default is '8' and is WAY too high. Pulling up a test pattern, it looks like '4' should be used and up to '6' can be used without too much damage done to the image. I also don't like that Brilliant Color is buried in the menu system as well and engaged pretty high by default. There is also no "off" setting. You can only choose from '1' to '10'. It really makes me wonder how serious the engineers were at attempting to make an enthusiast grade projector. When you don't have a '0' or 'Off' setting it makes things very confusing. Plus other odd things like including a speaker and a non-detachable lens cap (it just hangs from a string when it's not covering the lens) really make this thing feel like a cheap, plastic, business-grade projector. It honestly wouldn't surprise me at all if this projector was originally designed and intended to be sold in the business market and some tweaks here and there (black color chassis and RGB-RGB color wheel for example) were utilized to turn this into a "home theater" projector. All I'm saying is that a nice, well laid out menu system with settings that make 100% sense and a slightly high-end feel to the aesthetic and build quality go a long way into making your projector feel like it belongs with other actual "home theater" projectors.

There is no true fade to black on this projector. The level of black does go down a small amount more when there is nothing but an all black image on screen, but it's no where near as dark as a JVC, Sony or Epson unit that we often discuss in this ($3000+) forum. The lamp dimming feature is not invisible on this unit (nor is it on any other projector) but I would say it's definitely usable and most people will find that it's performance is good enough to be left on all the time. The relatively measly 1500:1 native contrast really needs help and Dynamic Black easily makes a noticeable difference but you may see some gamma shifts and small changes in brightness on occasion, but again, DB on this unit is better than I've seen on some other DLP units. If you get the chance definietly demo this projector or buy it from some place that has a good return policy and someone you won't feel guilty about returning a projector to.

I still feel that a JVC, Epson laser, and Sony 4K unit put out an obviously better image overall no matter if it's 1080p or 4K. This may be, however, the best currently selling DLP projector you can find in the sub $3000 market. The Vivitek HK2288 will probably be a better DLP projector than this Optoma, but the price point looks like it will be closer to $5000 from what I've read so far so they aren't 100% comparable due to the price difference.

It should be close. They only got their pre-production unit a few weeks ago if I remember correctly so it more than likely represented the final light engine design. I'm sure it was minor software changes that made that unit differ from the production units that recently shipped out to buyers.

I do have a relatively cheap SPL meter (this meter). Is there a specific distance you'd like for me to place the meter when I take my measurements? I haven't engaged high altitude mode, but I can tell you that High and Eco mode are essentially the quitest I've heard from any DLP projector I've had here and that number is in the dozens. It's impressive. It's about as quite as a JVC in low lamp mode, maybe a tad nosier. I'd say unless you were planning on mounting this projector directly above your head, most people will have no issue with noise coming from this projector. Though High Altitude mode might be an issue, but that's going to be the case with just about any projector out there, not just this one.

Thanks. Yes, high altitude is a pain when it comes to projector fans. I have a really nice, acoustically speaking, 7.2.4 atmos setup in my home theater using a Marantz Pre/Pro and GoldenEar speakers. I really like it but I often watch at night and I try to keep my volume low. The last thing I need is a noisy fan ruining the experience.

Basically, my projector will be mounted about 6 - 7 ft. above and behind me when I get one. I am waiting for CEDIA to see what comes out. My dream projector would be either a Sony 675ES equivalent under 8K or a RS620 equivalent with a laser light source. What would really make me happy is if they ran fairly quiet in high altitude mode.

Most of the time living at 8000 feet is great but it can play havoc with things like plasma tvs, cooling fans, and high dollar pressurized bulbs.

I would love to try one of these out Seegs as I havent experienced DLP for years due to the rainbows on most.

However I just dont see it working in my place, what do you think?
My proj lens, X9000 is 16" down from the ceiling, the top of my screen is 30" down from the ceiling.
I thought of making a stand to turn the projector upside down to get the offset I need.
The current proj is table top in a projection booth with heaps of room.

At this price it would be a good spare, yet nothing like the X9000 I know, but its no use if I cant get the image on the screen in my place

Placement of the projector is a pain too. It's really meant to be ceiling mounted as a decent amount of the vertical lens shift is only offered in one direction unlike what we normally get on the JVC/Epson/Sony units we typically discuss in this sub forum. It was a pain to get this projector set up high enough (without actually mounting it) to project properly on my screen.

When it comes down to it, no, this projector will not make you want to get rid of your X9000. You might be able to see a small amount of extra fine detail with this Optoma unit due to the higher native pixel count it has, but pretty much every other area of performance your JVC has this unit beat in. I would say hold on a few more months and see what Epson/JVC/Sony have to offer us in the fall as I'm sure one of those units will be the one to truly replace your X9000.

Anything 1080p sent to this projector, however, will have about 75ms of input lag. I'd also like to comment and say that RBE (rainbows) are hardly an issue. Considering the brightness, I'm surprised I haven't seen more of them. This is also the quietest DLP projector I've had here. It's as quite as a current JVC projector in low lamp mode and has the potential to put out about as much light as a JVC in it's low lamp mode. Kudos to Optoma for this achievement. I was beginning to think all DLP projectors were doomed to be loud.

These are just some quick thoughts and measurements. I hope you find it helpful. I'll be spending some more time later with this projector to see how HDR looks. I'm honestly surprised a bit at how good overall this projector performs. It definitely took me for surprise.
Wow that is frankly way better than I expected. I'd agree with Optomas "disruptive" marketing given this result.

Curious to see how the dynamic contrast is with content in terms of intrusiveness and effectiveness .

Also makes me excited for the UHZ65.

it's still ~1400:1 native + ~600 lumens low lamp, ~850 in high before full calibration.

how is that low lumen output going to work well with HDR? My 10 year old .95 Planar has the same lumen output @ D65/R709 and 2X+ better native.

850 in high lamp seems pretty low, is it close to D65/R709 @ that measurement?
One would hope so - can't afford to lose any more light output. Small screens only with those lumen numbers.

So does the Optoma have multi-point gamma calibration capability (10, 20 point)? That really seems to be key to getting good HDR on a lot of projectors.

It would be really interesting to see a solid comparison between these new "4K" DLPs and a truly good DLP like the Planar. HDR handled by the "4K" projector vs HDR->SDR (via Panasonic) to the Planar. I bet the Planar would win by a good margin.

I was thinking the same thing, a showdown between the .95 Planar and the Optoma would be very interesting to see.

I checked out Lucy UHD a few weeks ago on the Planar and it looked excellent. Plus the lens shift works perfect for my HP screen, I can go dead center for max gain. I don't like the lens shift limitations on these UHD DLP's, it feels like going back 10+ years ago + all manual controls, etc. The Sharp 30K has full lens shift (H & V) + lens memory.

It would be closer than you guys think. I would say the Planar might pull very slightly ahead with some darker content, but all of these DLPs will look a bit weak in that department. We're looking at ~5500:1 dynamic contrast versus 12000:1 dynamic contrast, which isn't as much as the numbers indicate. That's like a difference of 1 lux for the black level reading. I do think after seeing this Optoma unit that it is and will be easily sharper than any of the 1080p DLPs we talk about. Pixel sharpness is good enough that with the addition of four times more addressable pixels on screen that with a good source you could make an argument that the UHD65 is the "obvious" choice when it comes to fine detail rendering. I'm not in the camp that says ultimate resolution is the most important thing in the image (otherwise I'd have a Sony 4K here), but as we can see from some of these Acer V9800 pictures here which should be extremely close to this UHD65, it's obvious to see that there is a clear advantage in fine detail rendering over even Sony's native 4K projector. I think Sony needs to address it's relatively weak lens quality and fix a few other issues as this cheap-o Acer should not be giving an obvious advantage in image detail especially when you factor in not only the huge price difference, but also that the DLP projector isn't even native 4K. Looking at the single pixel test patterns, the UHD65 was showing LESS artifacts than the native 4K Sony 665ES. What's up with that? This is the first Optoma unit that I've personally seen that doesn't obviously suck. I do feel it's the best sub $3000 DLP unit out there currently. The Acer seems to have similar performance but has, according to cine4home, a loud and poorly implemented DI. That is a deal breaker considering the already weak native contrast. The lamp dimming in this Optoma unit does essentially the same thing, but I feel that it's actually quite usable. I don't think this unit is comparable in overall image quality to the Sony/Epson/JVC units we discuss in this subforum and I'm in no way advocating anyone into making the switch as I think overall it would be a downgrade.

Thanks for the info Seegs, do you think you'll have a chance to check out UHD content on it?

I'm actually having an issue with the HDCP 2.2 port on the Optoma. It does not want to play nicely with my Monoprice Redmere HDMI cables. I need to find another HDMI cable to be able to send a 10bit signal to the projector as the other HDMI port is only 1.4a and is limited to 8 bit it seems as that's the only bit depth that shows up for this unit in nvidias control center. Otherwise I would have checked out some HDR content last night.

The active Redmere cables do not work with. You will need a premium certified HDMI cable. They are pretty cheap, up to 25'. After that the price climbs rapidly.

For 60p yes, but they'll work fine for 24/25/30p content. I also just found the issue. For whatever reason it was trying to send a 12bit RGB UHD signal at 60p which is why I wasn't getting an image. That's fixed. Sending a 12 bit RGB UHD signal at 24p is working fine now with my Remere cable.

HDR was autodetected on the UHD65 and went into it's proper mode. I'll have to pull up some test patterns and make sure white is clipping properly.

I don't know the, contrast you're measuring on the Optoma is in the ballpark (maybe a bit worse?) that my W5000 had and my Planar was a good step up. The Planar has almost double the native contrast and almost 3x the dynamic. No, it's not going to knock you out of your seat, but it's significant.

I have no doubt about that, it's got twice the native resolution.

I'd love to see some pictures I'm really curious if they've improved things since those first test pattern pictures surfaced. I'm also curious how it handles 1080p test patterns.

Sadly that's not really saying anything anymore.

The W5000 I had here (and the Sim2 D60 clone I recently had here) was worse off for contrast. I only measured the Sim2 D60 in at 800:1 native contrast and a little over 2500:1 dynamic contrast. I don't think I measured the W5000 when I had it here, but based off of memory, I'd say the W5000 looked subjectively the same regarding contrast. The DC2 DMD used in these models was not good. Also, the DMD chamber was not treated with an anodized black light absorptive coating like we see in the PD8150. Heavy light scatter and the DC2 DMD doomed these units from the start. Even BenQ's W20000 (their best 1080p contrast performing .95" unit produced) only saw a little more than 1000:1 native contrast. See here for measurements. The UHD65 is much better than the W5000, but yes, a little worse off than the PD8150. What are you measuring your PD8150 in at? The stock DC3 DMD should be getting you a little over 2000:1 native (up to 2500:1) and 12000:1 dynamic contrast. Again, I don't think there's going to be a huge difference in subjective contrast between these units. Though you could argue lens quality is a lot better on these .95" DLP DMD units, but that goes without saying as the MSRP on those units was MUCH higher at the time so they could afford a better lens. I'd venture a guess that the upcoming Vivitek HK2288 will be the closest PD8150 replacement you're going to see. I'm guessing a better lens compared to this Optoma, a little more contrast and better HDR due to more lumen output. But it's going to cost more with an MSRP of around $5000. I don't know how well it's going to sell when you can get a JVC HDR enabled projector for the same price.
