Optoma UHD50

https://bhphotovideo.com/c/produ...ogy_uhd50.html

Enjoy UHD 4K content with HDR support with the Optoma UHD50 UHD DLP Home Theater Projector. Its 2400 lumens of brightness overcome ambient light in many installations, while its 500,000:1 dynamic contrast ratio helps enhance detail in dark areas of the image. The native 3840 x 2160 resolution helps ensure that text and images are clear. HDR10 compatibility ensures vibrant color reproduction from a compatible source device and content.
The UHD50 has one VGA and two HDMI inputs to support a variety of sources. Both HDMI inputs are MHL-compatible for connecting mobile devices, such as your smartphone or tablet, and the projector has a USB power output to help conserve your device's battery life. Its analog audio input and output allow you to either use the built-in 5W speakers or output your audio to an external system with the optical audio output, a digital audio connection to your receiver or soundbar. The projector is controllable via Ethernet, RS-232, or the included IR remote control.
UHD 4K (3840 x 2160) resolution, plus 2400 lumens of brightness and a 6-segment RGBRGB color wheel Equipped with HDR10 and DCI-P3 wide color gamut support for bright whites, deep blacks, and vivid color Dynamic Black delivers a 500,000:1 dynamic contrast ratio for enhanced black levels HDMI 2.0 and HDCP 2.2 offer UHD video bandwidth and device compatibility Vertical lens shift and 1.3x zoom provide flexible installation Two 5W speakers and an optical output to your A/V receiver or soundbar

I have owned 3 Optoma projectors and one sure thing I have noticed is that their specs for lumens and contrast are largely exaggerated in most cases as compared to the industry standards. 2400 lumens is probably close, but 500K contrast I seriously doubt. I have a 142x now and no way is it at the specs they say. Read the reviews/tests before you buy any Optoma product to know what specs you are really getting.

Anyone who's interested in how "native resolution" has traditionally been defined and how pixel shifting projectors like the UHD50 fit the definition can read and discuss that issue in the dedicated 4K thread linked to below. This thread should remain focused on the UHD50 and not devolve into another "my 4K is better than your 4K" side discussion.

I completely agree.

Also can we keep the JVC good, DLP bad talk out of this thread. You know who you are.

Any more information on this? From my understanding it seems to be the uhd60 but with a rgbrgb wheel which should help the black levels.

The rated lumens seem to vary from model to model vs real performance, hard to gauge what real performance will be.

But with Optoma you can use the fake contrast specs to get a handle on how it will rank, though, compared to other similar models.

For instance, in optima's fake numbers:

MOST CONTRAST | UHZ65 > UHD65 > UHD60 > UHD50 = UHD550X | LEAST CONTRAST


I am guessing the lens used in the UHD50/UHD550X is of lower quality and lower contrast than the one in the UHZ65/UHD65/UHD60.

Oh snap, this could be the one that I need if it has a shorter throw.

When is it out? WHat's the price?

Is there a calculator for this beast?

Not sure, B & H has it for pre-order at 1699, 100 below the current price for the UHD60.

Shocking lack of info about this thing.

BH photo has it, and that's about it.

Google brings up nothing.

I mean, they have it on their site. Not in stock.

Not a lot of other sites even know it exists.

Some more info on their site, with pics:

This site claims to have it in stock, and has a price of $1699

I'm kinda dumb, how does that compare to the W1070 (which I currently have and it fits my room better than any because of it's shorter throw)?

That’s 1.15-1.5 just a ruff estimate here: given a 120” screen you would need approximately 6”-8” longer distance for the UHD50. Projectorcentral should have it in their distance calculator by the time it’s for sale.

Thanks! Yeah I've been checking the PC calculator every 45 minutes

Do we have a release date on this guy? And would we expect Keystoning?

Nothing like lusting after 4K resolution and then throwing part of that higher resolution away by using digital keystone correction.

Also, since Keystone Correction is a digital process, it uses compression and scaling to manipulate the shape of the projected image which can result in decreased resolution, artifacts, and often, the results are still not perfect. This means you may still have image shape distortion along the edges of the projected image.

Should know more once the embargo is lifted.

Heh...well it's nice to have the option in worst case scenario. My W1070 has no Keystone in use. Ideally I won't need it.

If the UHD50 is the same as the UHD60 in offset and lens shift then it will have zero offset and 15% vertical lens shift. So with a ceiling mount you should be able to mount it in a range of heights from having the center of the lens even with the top of the screen's image area to as much as 15% of screen image height above that. If you aren't using keystone correction with your W1070 then a UHD50 should mount in the same location.

EDIT: Well, Optoma's description on the UHD50 data sheet is a bit odd. It says: "15% offset (with tolerance +/- 5%)." While that's identical to what the UHD60 data sheet says the UHD60 user manual clearly states that offset ranges from zero to 15% of image height. You might want to check in the UHD60/UHD65 owner thread to see what the real world offset is from user experience.

I sure do miss the insane Epson lens shift that i used to have. That thing dialed in so well.

I have used both lens shift and keystone separately on my benq 1070 and I can't tell the difference.

Throw Ratio is listed on their data sheet at 1.21 - 1.59 so it's a hair longer than the 1070


edit : sorry bix already nailed that one...

I appreciate double confirmations

I may need to drop to 100" to be safe. I'd be okay with that. 110" that I have is just a HAIIIIR too big. It's good, but I wouldn't miss the 10".
