      Are DLP tech units that can do WCG going to hit consumer space any time soon? The constant stream of REC709 units would say not...

      Looks like it has the larger 0.67" chip rather than the smaller on previously mooted.

      I just don’t get how they say it’s HDR yet it’s only rec709 and doesn’t do BT2020 which most UHD Blurays are I believe.....
      Manufacturers like to cut corners for us consumers a lot these days.

      It'll be awful. Don't go near it. Save up for an Epson TW7300.

      This isn't "cutting corners", it's a manufacturer providing solutions at a variety of price points. You can still buy your top end machinery if you have the desire and the wallet.

      I was on the main Optima 4K webpage, where it states that it uses a .67" chip and lists the various UHD models (40 and 300x included). There is no explicit mention of the smaller chip though. Where do you see that?

      The UHD 50 and 51A look like the same small chassis, on the Optoma USA site they show 0.47" chip on specs page

      You're probably right. But it is plausible that they have launched different tech/models for different US/UK market.

      I don't think they're cutting corners. I think there is something about colour wheel DLP which makes it unable to do WCG. Unless I'm mistaken there aren't any WCG colour wheel DLP units yet?

      Yeah its rather dissapointing the lack of WCG, the lack of 3D on the higher end 4K DLP also annoys me losing functionality and maybe 15% Of my film viewing.
      .

      1st result on googling "wcg color wheel"

      briefly mention WCG and DLP but its a rather old article.

      The question for me is did I spend too much on my £1714 UHD60 back in November. Eek.

      I have a UHD550x sat unopened in my living room that was delivered Monday. If this uhd40 really is a 0.67" chip, then the 550 is going back in favour of this UHD40 which is clearly it's newer replacement. But if it is 0.47" chip I think I'll keep the 550.

      Why ? I thought the rationale behind the .47" was that it was a 1920x1080 chip which eshifts for want of a better term 3 times so that it's actually generating the correct number of pixels for UHD rather than the .67" chip which only eshifts once but has more pixels to begin with. I've yet to see a review to say which approach yields the better image.

      The UHD40 falls well short of the UHD60 in both light output and flexibility, (It is smaller though) so stick with your UHD60, which at the rice you paid is one of the best deals I have seen. (Where did you get this deal from?, best I have seen is £1999 which is still cracking for those that want to get into 4K)

      Compare the specs on the Optoma website and you will soon see the cuts that have been made to get the UHD40 down to a price.

      The only time I have seen the 0.47 chip mentioned is with the new entry level Benq 4K DLP projectors,

      Guys, all this talk about the size of chip is kinda missing the greater point. I calibrated an HD65 recently - which is nearly twice the price of this UHD40 - and I have to say it was shockingly bad. HDR? Forget it. With such poor black levels and contrast it has almost no dynamic range to speak of and it could barely achieve Rec709 in its 'HDR' mode because the raised light output washed out the colours. The Epson TW7300 is a much better projector than any of these Optomas; if you can stretch to the TW9300 you will be rewarded with a phenomenal picture for both SDR and HDR.

      Ok, so I contacted Optoma and they responded (very quickly!) that the 40 and 300x are both on the 0.47" chip.

      Did they say how many discrete images are shown on screen (One after the other), as if it’s just 2, (Like the units with the 0.66 chip) then it will be the same resolution as JVCs E-Shift (4.15 million pixels) which also uses 1080P Panels? (Although I would still take the JVC over 4K DLP (0.66 chip) and Epson 4K Enhanced, as it gives a more complete picture, (Personal opinion) I just wish they weren’t so expensive)

      Personal choice, but for me I find the Epson’s do not look like 4K (Even at normal viewing distance) and when put side by side with both the 4K DLP and JVC projectors all the fine details are totally missing on the Epson, (Haven’t seen the laser version though) but they do WCG and passable HDR, which combined with convenience features means they are a viable option, but not for everybody.

      Of course it's personal choice, but having calibrated these UHD Optomas I would say that they are really poor projectors, 4k or not (and of course they aren't true 4k panels themselves). Btw, I've had a native 4k Sony VW520 and JVC X7000 side by side (both calibrated) and while the former did in fact look more detailed it was only marginal. The biggest and most impressive difference was in the black level and contrast and (in HDR colours due to WCG). Speaking as a calibrator I have to say that the leap in resolution perception from HD to UHD is nowhere near as visible as SD to HD and nowhere near as important as black, level, colour and contrast.

      Yeah, prices do seem higher than usual at the moment. Sadly 'usual' has often been the same numbers on the price tag, just in pounds rather than dollars!

      Ordered an Optoma UHD300x from Amazon.de yesterday. Seemed a bargain at £970. Looks almost identical to the UHD40, albeit with lower contrast and brightness on the spec sheet. Will report back with impressions. It's replacing my Benq w1070.

      I have a uhd300x and the image has a very noticeable light border on all four sides. I find it quite distracting, but not sure if it’s expected with the new .47 chip set.

      Yes, unfortunately that's expected on these new 0.47 chipsets. I've got mine setup now and am pleased with it. Light border is there but I find I don't notice it too much. Black levels aren't brilliant, as is to be expected but overall the picture is superb for the £960 I paid.

      Anyone found any suggested calibration settings for the UHD40? I'm still using mine as it came out of the box (for a few months now). No idea what I'd meant to be doing with the settings.

      There’s little point in shared settings especially with projectors as so much is unique to the projector and room. Look into having it professionally calibrated for the best, most accurate picture or invest in some DIY calibration gear and learn about the process of calibration yourself. Hope this helps.

      Fair enough. If it was a very common PJ i might have been able to see a consensus forming and use that as a base. But seeing as there's little talk on it, it does look like I'll work it out myself.

      I have this unit for about a week now, the out of box settings would have made me return this unit,I am using the cinema film mode on eco lamp setting ,Hav3 tried a few 4k movies & had some very good results I will post some pictures soon.I suggest doing a search on you rube & having a look at a few reviews & adjusting the settings to your preference , at the moment I am using a cheap screen & have decided to invest in better screen now.
