Would seem odd if this uses the 0.67" chip instead of the 0.47" that's in the other cheaper Optoma 4K ?, Where have you seen the info about the larger chip ?Looks like it has the larger 0.67" chip rather than the smaller on previously mooted.
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 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.
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?Would seem odd if this uses the 0.67" chip instead of the 0.47" that's in the other cheaper Optoma 4K ?, Where have you seen the info about the larger chip ?
There is also another one on the Optoma site. Seems identical . Like the UHD550x vs UHD60 version.

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

You're probably right. But it is plausible that they have launched different tech/models for different US/UK market.The UHD 50 and 51A look like the same small chassis, on the Optoma USA site they show 0.47" chip on specs page
Optoma UHD50 DLP High Definition Home Cinema Projector
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.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?
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.
Ok, so I contacted Optoma and they responded (very quickly!) that the 40 and 300x are both on the 0.47" chip.
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.
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.
