Optoma UHD35 Projector Assessment: Fabulous 4K Image For The Value

The UHD35 is a 4K projector that prices just a few hundred greater than many 1080p projectors. It is shiny, has pretty correct colours and appears much better than you would possibly anticipate of a “finances 4K projector.” And it serves up eye-watering element on a huge display screen, the type of sharpness that no 1080p projector can match.

Whereas general the picture on the UHD35 appears good, it nonetheless has the identical points frequent amongst projectors comparable in value. There is no lens shift, the zoom is minimal and the distinction ratio — a side of picture high quality much more necessary than element and determination — is pretty common. It is also noisy, which is true of all small projectors, however the sound from the UHD35 is extra wheeze than whirr. After which there’s the HDR image high quality, which is improved over the sooner UHD30 however nonetheless not nice.

Total although, the UHD35 appears actually good: Shiny, vibrant colours, 4K element, all in a projector that solely prices just a few hundred greater than some nice 1080p projectors just like the Epson HC2250 or BenQ HT2250A. In case you’re seeking to step up in sharpness with out going too far into debt, it deserves sturdy consideration.

The UHD35 is a 4K projector and, as you’d anticipate, can settle for a 4K sign as much as 60Hz. Apparently, it could additionally settle for 1080p as much as 240Hz, if you happen to’ve bought a gaming rig able to such a framerate.

One spec enchancment of the UHD35 over its predecessor is its claimed gentle output, now at three,600 lumens. The UHD30 was no slouch both, at three,400. I measured near the identical on each, technically barely much less with the UHD35, however the distinction was effectively throughout the vary of measurement error and unit-to-unit variation. The purpose is, they’re shiny. 

There is no lens shift, not a giant shock for a DLP-based projector on this value vary. The zoom vary can be somewhat meager, at 1.1x. So the vary of distance from the display screen is proscribed, placement-wise.

Whereas many different projectors have been dropping inputs, the UHD35 retains a number of that appear virtually anachronistic in a house theater projector in 2021. There’s nonetheless an analog RGB enter, as an example. 

For the house automation crowd, there are RS-232 and 12v triggers. For the exact opposite of that crowd, if you wish to plug in a speaker on to the UHD35, there are three.5mm analog outputs and an optical digital output. There’s additionally a USB connection that may energy a streaming stick.

A noticeable change from UHD35’s predecessor is a second HDMI 2.Zero enter.

Image high quality comparisons

The BenQ is our choose for finest PJ for the cash general. It is solely 1080p, however its coloration and distinction are so good — and I’ve seen how far above its weight it could punch — it appeared like a logical comparability. The UHD30, one in all our favorites from 2020, is the direct predecessor to the UHD35. I linked the 2 Optomas through a Monoprice 1×4 distribution amplifier. The BenQ, being 1080p, bought its personal supply. I seen all of them, side-by-side-by-side on a 12-foot-wide 1.Zero-gain display screen.

Among the finest issues about DLP projectors is, basically, how sharp and detailed they’re. They’re the one present show know-how with no semblance of movement blur, so even at 1080p the BenQ could be very sharp, even with movement. Nonetheless, the Optomas are a lot sharper. Projectors and the massive photos they produce are the easiest way to see 4K content material. The sharpness does draw the attention, with fantastic particulars like hair, wrinkles, cloth textures and so forth way more obvious and lifelike with the Optomas. Neither are fairly as sharp because the way more costly LG HU810P, however higher lens optics is likely one of the belongings you get whenever you spend more cash. 

Coloration-wise, the Optomas and the BenQ are fairly comparable, which is to say good. In contrast to many DLP projectors, these three have correct colours. So the whole lot from background skies and sea, pores and skin tones and hair, all look real looking. I might give a nod to the UHD35 with HDR content material, however we’ll get to that in a subsequent.

Usually, the UHD35 appears higher than the UHD30 with HDR. This is not as a result of it is brighter, or has a greater dynamic vary. In each instances they’re practically similar to the UHD30. It appears Optoma has improved its HDR remapping — the method of changing the HDR supply to finest match the show’s capabilities. This course of is necessary with nearly each show, however particularly with projectors since they’ve neither the sunshine output nor dynamic vary to do HDR effectively. So HDR content material must be remapped to be watchable.

The picture on the UHD35 is, on common, brighter (even with the identical settings). It additionally has far much less banding, an artifact that appears like abrupt bands the place there ought to be clean transitions from shiny to darkish or one shade to a different.

A superb scene to point out this off is the opening flying combat from Falcon and the Winter Soldier. The brilliant sky and clouds on the UHD30 present banding dangerous sufficient that even informal viewers would marvel if there was one thing unsuitable with the projector. The UHD35 would not have this challenge, although on some content material I nonetheless noticed some banding. In case you discover it and are bothered by it, you do not lose a lot simply turning off HDR in your supply. 

Distinction has by no means been a DLP sturdy go well with and the 4K chips appear worse than their 1080p predecessors. The 2 Optomas have principally the identical distinction ratio, within the mid 600s, which is way lower than the BenQ. It is nonetheless the crowning champ in that regard at over 2,000:1. In consequence the BenQ’s picture has extra depth and extra punch to it. That mentioned, the UHD35’s 649:1 is on par with just about each different 4K projector I’ve reviewed within the final yr and better than some far costlier projectors. 

Which is to say, the BenQ holds its personal towards projectors that value practically twice as a lot and with 4x the decision. That additional decision although — on a 100+ inch display screen and with a distinction ratio that is not dangerous, plus nice coloration — does make the UHD35 eminently watchable.

Extra of the identical could be a good factor

Aspect by facet, there is not a large distinction between the UHD30 and the UHD35. That is not a nasty factor. The UHD30 was one in all our favourite projectors final yr — and one I saved going again to after I was between projector opinions. The brand new mannequin is a bit more colourful, which is definitely pleasing to the attention, and positively decodes HDR higher, even when there’s little actual efficiency profit to the HDR itself. If you have already got a UHD30, there is no cause to improve. 

Nonetheless, I feel it is protected to imagine the overwhelming majority of you studying this do not have a UHD30 and are coming into this simply in search of a cheap 4K projector. In that case, the UHD35 is nice. It’s shiny, has pretty correct colours and creates an general extremely watchable picture. It is not as shiny as some, nor does it have as excessive distinction ratio as others, but it surely does provide 4K decision for $1,300 which is a good deal. In order for you the additional element of 4K, with out sacrificing coloration, brightness, or your pockets, but can nonetheless afford spending greater than $1,000 on a projector, the UHD35 is a good alternative.

Measurement Notes

For probably the most correct image I used the Cinema image mode and the D65 coloration temperature mode. This resulted in a picture that was somewhat too heat, as in barely missing blue, throughout the brightness vary. 

Gentle output was stable in each mode. Within the Cinema mode I measured 174 nits on a 102-inch 1.Zero acquire display screen, for a lumen equal of 1567, roughly the identical as different 4K DLP projectors in its class. If you wish to sacrifice coloration and coloration temperature accuracy, the Shiny image mode bumps that as much as a formidable 308.eight nits, although the general picture is far worse.

Coloration is kind of correct, with crimson, inexperienced, blue, cyan and yellow all on or near their Rec 709 targets. Magenta is barely crimson.

Distinction ratio, as typical with 4K DLP projectors, wasn’t nice however roughly the identical as its opponents. On common, I measured a local distinction ratio of 649:1. For reference, that is lower than the 1080p Epson 2250 (1,026:1) and BenQ HT2050A (2,094:1, one of the best in school), however larger than the $three,000 4K LG HU810P (490:1). The Dynamic lamp mode tracks the incoming video sign and varies the lamp output accordingly. On this mode, the UHD35 has a dynamic distinction ratio of two,034:1. The Eco+ mode does the identical, however limits the utmost gentle output for higher power effectivity. On this mode the dynamic distinction ratio is 1,173:1.
