![]() ![]() And none of them (thankfully) replicate the extreme HDR pictures seen on flat panel TVs, which tend to look supersaturated, digitally over-manipulated, and basically fake. None of these new low priced 4K projectors match the dynamic range of the more expensive home theater projectors from Epson, JVC, or Sony. So it is an appealing feature, and combined with the 4K resolution it delivers a beautiful picture for the money. On the UHD50, the HDR picture is a moderately higher contrast image than you get with non-HDR sources. We would not push image size much beyond 120", as the larger one goes it lowers effective contrast.ĤK HDR Performance. In order to optimize results, use this projector in a dark viewing space with no ambient light. Overall, the integrity of the picture was compromised in this mode and we preferred to avoid it and stick with the more refined Cinema mode. Some users might like this effect on some material. Compared to Cinema mode it alters the gamma, reduces color saturation, shifts color balance, and adds a bit of harshness. HDR Sim sounds like an intriguing feature that would lend some extra contrast to an SDR source, which it does. The UHD50 has a color mode called HDR Sim which is an option for non-HDR source material. By setting Ultra Resolution to 1, the picture from 1080p sources is improved in sharpness without introducing significant noise. The default is Off, with options of 1, 2, and 3. This projector has an Ultra Resolution function which essentially sharpens the picture. This will reduce the brilliance of white without having much effect on the brightness of color, and the result is a more balanced picture overall. Some people do not mind this effect as it gives the picture an added "pop," but those looking for optimum balance may want to pull Brilliant Color down to 5 or 6. When you are in Cinema mode and Brilliant Color is set to its default of 10, large white objects in the image appear brighter than they should relative to colored elements. On the other hand, when a largely black image appears such as a title screen or rolling credits, the black level is quite solid and satisfying. It is sufficient to avoid muddiness in shadow details, but not as high as one might expect from a projector with a contrast rating of 500,000:1, and not as high as home theater projectors in the higher price ranges. The UHD50 has a 1.3x zoom lens that loses 11% of the projector's potential light output at the telephoto end compared to the wide angle end.Ĭontrast is best described as adequate. There is an Eco lamp mode which reduces lumen output by about 33%. If you reduce Brilliant Color to 3, color brightness equals 100% of white, and total ANSI lumen output is reduced by 19%. In Cinema mode, at Brilliant Color's maximum of 10, color brightness is equal to 80% of white which is still sufficient color in the signal to render very good saturation. The UHD50 has a ten-step Brilliant Color feature that defaults to the maximum of 10 in all modes except Reference, in which it is turned off. ![]() You won't want to use Bright mode for any video display unless you don't mind a green picture. As is typical, this projector has a very bright factory calibration, called "Bright." The brightest modes on most projectors tend to be skewed toward an obvious green and this one is no different. The Optoma UHD50 is rated at 2400 lumens. Thus, for a variety of reasons, the Optoma UHD50 at just $1499 is a unique and excellent value in home theater projectors.īrightness. Moreover, the Optoma UHD50 is a handsome unit - a beautifully designed and crafted machine that simply looks and feels good. So buyers with smaller rooms can get a bigger picture with their available throw distance from the UHD50. Another key feature that will generate buying decisions in the UHD50's favor is its short throw ratio - it can fill a 120" diagonal screen from a throw distance of as little as 10.5 feet while competing units like the ViewSonic PX727-4K and BenQ HT2550 require about 13 feet.
