      Is the price accurate? If correct this makes it cheaper than the inferior UHD40. Most of the European Amazon sites are listing at 1800 euros+

      This sounds amazing... I could finally replace my LG with this one.

      I've just imported the UHD 60 from the US as was much cheaper then the rip off UK pricing. I wonder how this compares?

      The £ is worth more than the €, hence the lower price in the UK.

      As far as I am aware the UHD51 uses the 0.47 chip which requires 4 flashes to produce 8.3 million pixels, whereas the UHD60 uses the 066 chip which only requires 2 flashes to put 8.3 million pixels on-screen, so with less processing involved it should theoretically be better. (Whether there is a difference you will need to go and demo to compare, although the 51 does have frame interpolation whereas the 60 does not, so the 51 may be better with sports)

      At the current exchange rate £1499 is less than 1800 euros which is what most of Amazon's European sites are selling at. Generally I find it normally the other way round with the UK being more expensive. I would be interested to see what price the UHD350X retails at if anyone knows.​

      I do love my UHD60, and in 3 years, I never used 3D, so when I first saw this I thought, damn, 3d for cheaper than what i paid, but now I am okay because the UHD60 should be a better projector overall

      I wonder if Optoma will ever produce a decent 3D capable DLP 4K native HDR projector with a substantial chassis for quiet operation, a centrally mounted lens and V&H lens shift ?.

      It all comes down to cost as Native 4K DLP chips have been in use for donkeys years, (They are just reserved for professional environments (Usually 3 of them in one projector) though) but they are big and would take extensive re-working to make them suitable for the domestic environment, so not cost effective at present. (Eventually it will come as technology advances (Just like affordable Native 4K JVC projectors will come) but will probably be a few more years yet)

      agreed....Like a few on here, I'm getting sick of manufacturers producing blurbs that are essentially lies. For example A recent review from a manufacturer stated 4k UHD projector....but upon AVF reviewing it they clarified " It uses a new smaller Texas Instruments 0.47” DMD DLP chip which is 1920 x 1080 in resolution, but it uses an extremely fast mirror flashing technique to move the mirrors four times within a single frame to create an image that has 8.3 million pixels on screen. So whilst it is not a true 4K Ultra HD native resolution chip being used, it does produce the pixel count on the screen"....so it simply a faux 4K image....up-scaling essentially.

      Once again I hope we're NOT going down the True HD / HD Ready / Real 3D / Faux passive 3D route again....this type of stuff will be the ruin of 4K.

      If this is a true 4K UHD none faux upscale thingamijig....I may just consider buying it.

      I just checked over at the AVF forums....it appears it is a true 4k projector., but people are basing it on spec sheets....time will tell...I've emailed Optoma asking if its a true native 4k or pixel shift...

      Sadly not, it's a 1080p pixel shifter. The manual you linked to gives the game away on page 52:

      "Native resolution (w/o actuator) 1920x1080"

      Most of my viewing in 1080p currently. I'm looking to upgrade to 4K, and this seems like a good option. How would this compare to the Sony HW40 for 1080p pictures and 3D? 3D is important for me. I've discounted the Epson projectors due to poor 3D. And JVC 5900 is more than twice the price, while Sony's native 4K option is more than thrice the price.

      Surely this is false advertising? It is not true 4k and uses a system to generate pixels... personally I'm getting sick of this...it's essentially deception

      Yep, it’s worse than the ridiculous ‘HD Ready’ vs ‘Full HD’ debacle from years ago.

      The latest buzz-word seems to be ‘4K pixels on screen’ and it should be stopped as it is deliberately trying to confuse people into thinking that the projector is not just a pixel-shifter.

      I’d be very surprised if any projector at this type of price does true 4K for quite some time.

      I guess there will be a lot of people who aren’t particular enthusiasts that will buy this and never know the difference, so you can understand why they do it.

      And here you have it...an email I got today direct from their marketing manager...

      ,.........
      Thank you for your email.



      Optoma 4K UHD projectors display 4K UHD resolution (8.3 million on screen pixels) which is approved by the Consumer Technology Association (CTA). Although this is not native 4K, the DLP® chip used in the UHD51 has over two million mirrors and delivers four pixels per mirror. The inherent fast switching speed of the DLP chip and Texas Instruments’ latest XPR™ technology allows the UHD51 projector to display the full 8.3M pixels to the screen from this DLP chip.


      This is very different technology to the ‘4K-enhanced’ 3LCD projectors that use native HD1080p chips (1920x1080) that only produce 4.15 million pixels - half of the 8.3 million in a native 4K signal.

      Just to clarify. The UHD60, UHZ65 and UHD65 use a 4M pixel chip which produces two discrete images per mirror. The UHD51 and UHD40 use a 2M pixel chip which produce four discrete images per mirror. I have just updated the blog on this to try to make this more clear and help dispel any confusion. With the full 8.3 million on-screen pixels, Optoma’s 4K UHD projectors meet the Consumer Technology Association (CTA) requirements for 4K UHD. I hope this helps.

      To be clear though, these 'on-screen pixels' are not the same 8.3 million pixels that constitute the original UHD image. XPR technology cannot address discrete pixels in the same manner as a native 4K panel can - any suggestion that it can is marketing puff.
