Optoma UHD55 NPA frontangle

Optoma has announced a new lamp-based gaming and home entertainment projector, the UHD55.

With a street price of $1,799 out of the gate ($2,599 in Canada), the UHD55 uses the 0.47-inch DLP chipset that achieves 4K (3840x2160) onscreen resolution with four-way XPR pixel shifting technology. The projector's lamp is rated for 3,600 ANSI lumens and has a life expectancy of 10,000 hours in Standard light mode (4,000 in Bright mode, and up to 15,000 in Dynamic Black mode). Optoma lists a contrast ratio of 1,200,000:1. The UHD55 has vertical lens shift, a 1.3x optical zoom with a throw ratio of 1.21-1.59:1, and support for vertical keystone correction and 3 x 3 warping.

For HDR, the projector supports HDR10 and HLG signals, and wide color gamut support at 97% DCI-P3 coverage with a shutter enabled. 3D is also supported in side-by-side, top and bottom, and frame sequential formats. Smart home compatibility for Amazon Alexa, Google Home, and IFTTT is also built in.

Optoma UHD55 NPA lifestyle

While the UHD55 supports a refresh rate up to 240Hz (from a computer), 4K is limited to 60Hz due to Optoma's including only HDMI 2.0 (with HDCP 2.2) for both inputs. (The introduction of HDMI 2.1 ports on most DLP projectors has lagged due to limitations of the most common chipsets.) Still, the input lag on the UHD55 is impressive at 16ms with a 4K/60Hz signal and down to 4ms with 1080p/240 signals.

The form factor of the UHD55 is identical to the earlier UHD35 and UHD38, measuring 4.6 x 12.4 x 10.6 inches (HWD) and 8.2 pounds. It comes in white and is available for purchase now.

the lack of a proper hdmi 2.1 is a real head scratcher

Still no HDMI 2.1? I have the UHD50X which has one 2.1 jack and one 1.0 What gives?

Seems like a run of the mill projector. What is its claim to fame that sets it apart from other similar projectors? What is the reason to buy -pricing? Without HDMI 2.1 support it’s just a “Meh” for me.

I need an upgrade from my gt1080darbee but will refuse it until a -2k projector with full bandwidth hdmi 2.1 port is available.

Chaz, you are mistaken about the UHD50X -- it has only an HDMI 2.0 port and has no ability to accept 4K/120 content, which is the main reason to have HDMI 2.1

To clarify; the limitations of the current 0.47-inch 4K DLP chip and the associated processing prevent the ability to add HDMI 2.1 while maintaining low input lag with 4K/120 signals. This is why Optoma and BenQ -- who only use DLP imaging technology in their projectors -- have not yet released products with HDMI 2.1 I think I've heard that a new chip is on the way but needs to make its way into product plans. We're looking at seeing those next year probably.

Robin, Texas Instruments doesn’t have ANY 4K/120 Hz capable chipset currently, no matter the size (at least based on their 2022 publications). Do you know of TI release plans for support of 4K/120 or can you point us in that direction? It would be great if you could get a rep from TI to comment on the state for DLP development in PC blogs or as an article. Would love to see this!

I've have my eye on the UHD38 for a while now for project mapping and movies with 4000 lumen. That one costs 1100 euro over here, while the UHD costs 1500 euro. Besides the 'smart' stuff is there a huge difference? Better colours I've read. They look basically the same to me, except the old model has a higher output and a slightly different throw ratio. I'm not sure how noticeable 3600 vs 4000 is since I might not always use it in a dark room, I tend to want the output as high as possible. One can use eco settings to dim it, but not create sone extra lumen.

Since I'm planning of having two, the price difference is something real. Is 400 euro difference worth it on extra quality perhaps, when the output is lower?

I too was wondering about the difference between the uhd38 vs the uhd55. Will it be worth the extra price?
Rob Sabin, Editor Posted May 11, 2022 2:19 PM PST
Guys, I'm not really sure why there's such a significant price difference between these two but we have one coming in for review and we'll try to qualify how its different.

Rob, keep us posted. Interested to see how the uhd55 compares to the uhd38. Right now I'm leaning towards the uhd38 since I've got a 180" screen.

Hey, any news for the review ? I’m about to buy it…
Rob Sabin, Editor Posted Jun 19, 2022 3:35 PM PST
We have this review in for edit now and will publish it shortly. The UHD55 reviewed favorably as a high-value gaming projector, though our reviewer Sammie Prescott noted that it can either achieve its promised max of 97% DCI-P3 gamut OR ultra low latency for gaming, but not at the same time. These features are only available on separate HDMI ports.
Max Posted Aug 19, 2022 9:39 AM PST
I am curious how the UHD55 compares to the slightly older UHZ50X. One spec mentions that it can properly switch between 16:9 and ultra wide display signals. Is this true?
