The HC 4000 is not programmed to push color saturation nearly to the degree that the UHD60 does. The UHD60 automatically applies an abundance of color saturation that some users will interpret as a rich image and others will consider overdriven. We found a setting around 6 to be a more satisfying trade-off between brightness and contrast.īeyond this, these two projectors are programmed to interpret HDR signals differently. You can reduce BrilliantColor in steps, sacrificing brightness and increasing contrast to your taste. However, in this mode it automatically sets BrilliantColor to 10, which is the brightest and lowest contrast option. Meanwhile, the UHD60 has only one HDR preset that it defaults to when it gets a 4K HDR signal. It is a matter of taste which level you might prefer. On top of all that, the Epson 4000 has five different levels of 4K Enhancement processing, each increasing level of which boost perceived sharpness of the image. ![]() If you activate HDR in Bright Cinema mode, you get a brighter HDR picture than you do if you activate HDR in Cinema mode. Those in turn can be set to High, Medium, or Eco lamp modes. But on the HC 4000 there are four independent HDR calibrations of color, brightness, and gamma settings, and these in turn can be applied to any of the standard color presets-Dynamic, Bright Cinema, Cinema, etc. On many projectors, HDR is a unique color/gamma/brightness preset that kicks in when the projector sees an HDR signal. It is difficult to compare these two since both can be set to deliver HDR pictures numerous ways. However Epson released a firmware update in December that improved the HC 4000's HDR performance, making it more competitive with the UHD60 in HDR than it had been. On its initial release last year, the HC 4000 was not performing as well as the UHD60 with HDR-the picture just was not very bright. Both projectors make 1080p source material look a lot sharper than it does on native 1080p projectors. But it would be a mistake to consider the differences to be of any consequence. Practically speaking there is not much difference in the results on these two models, and sometimes the Epson 4000 actually appears to be the sharper of the two. In this case both projectors are upscaling the native 1080p signal to approximate a 4K picture. The results are somewhat different with HD 1080p video sources. The difference is particularly visible in fine hair and fabric detail when the two images are viewed side by side. ![]() Thus, with a 4K signal, the Epson 4000 produces a remarkably sharp, close approximation of a 4K image, and the UHD60 produces a noticeably sharper 4K image. In practical terms it generates a picture that, with film/video subject matter in home theater use, is indistinguishable in resolution from a native 4K projector. The UHD60's chip uses pixel shifting too, but it has 2716 x 1528 mirrors on the chip, or double the elements compared to a standard 1080p device. But in order to hit that price point last year they incorporated just the bare essentials with very few features other than 4K display. Optoma was the first maker to bring the 4K UHD DLP chip under $2,000 with the UHD60. The Optoma UHD60 uses the 0.66" 4K UHD DLP chip in order to maximize picture resolution with 4K source signals. ![]() ![]() This technology does not display native 4K signals with quite the same precision as the 4K UHD DLP chip, however it does produce a very sharp image that looks substantially higher in resolution than you'd expect to get from the native 1080p chips that produce it. It accepts 4K native signals and displays them with pixel-shifting on native 1080p 3LCD panels. The Epson Home Cinema 4000 is essentially a Home Cinema 6040UB/5040UB with a different color compensating filter and the lens iris removed, two changes which affect contrast and lumens. There could not be two more radically different projectors in terms of both 4K technology and features/functionality. The Epson Home Cinema 4000 and the Optoma UHD60 are both 4K-enabled home theater projectors in white casework.
