Penjelasan Produk

The UHZ65's image quality for film and video is every bit as impressive as you would expect from the price. Along with fine detail, it delivers rich, natural-looking color and both a high enough contrast ratio and the subtle shading needed to add a convincing sense of three dimensionality. Surprisingly, given the visibly high contrast, a solid black image has a noticeable glow in a dark room. However, the black areas don't get any brighter if you add bright elements to the image, which is the more important factor for contrast.

There is also no visible change in black level when you change brightness by adjusting the power level, which has settings from 50% to 100% in 5% increments. So the higher the power level, the better the contrast will be. If you use the UHZ65 with a small screen in a dark room, you may have to settle for somewhat lower contrast, since the higher power levels may be too bright. However, this won't be an issue for the screen sizes you need in order to see all the detail available at 3820x2160 resolution, particularly in a room with ambient light.

 

Color accuracy with default settings for the Cinema color preset is good enough to use straight out of the box. There's a slight blue bias compared with a calibrated projector, but it is easy to adjust to neutral color. And unlike most color presets for DLP projectors, Cinema mode is designed to offer accurate colors with Brilliant Color at 10--the highest setting--for maximum white brightness. Most of the same comments apply to Reference mode, except that its default setting for Brilliant Color is 1, which translates to being off. Reference mode also has lower contrast than Cinema mode.

Bright mode has an obvious magenta shift with default settings, but color accuracy improves significantly if you drop Brilliant Color to 1 from the default of 10. Game mode maintains color accuracy fairly well and delivers good contrast, but it loses subtle gradations the eye uses as cues to three dimensionality. The loss in depth won't matter for games and animations, and the high contrast will be a plus.

There's also an HDR Sim mode that's meant to add an HDR look to SDR content by enhancing gamma, contrast, and color saturation. The enhancement goes a little too far, however, leading to oversaturated color. The actual HDR mode is available for HDR input only, and does a far better job.

You can customize any of the preset color modes or the one User mode to taste. In addition, the UHZ65 is ISF certified, so if you pay an ISF-certified technician to calibrate it, the menus will also include ISF Day and Night modes. The color modes in the menu also includes 3D, but there is no support for Blu-ray 3D. The UHZ65 supports only PC-based 3D.

 

Optoma's version of Frame Interpolation (FI) is called PureMotion. As with any version of FI it introduces a digital video effect that can be a distraction for watching film but can enhance the crispness of live or recorded video.

 

With default settings for Cinema mode, PureMotion is on and set to 1, the lowest of its three levels. Level 1 smoothes motion only a little while adding a slight, but obvious, digital video effect. Both increase at each step, with judder completely gone at the highest level, and filmed content looking like live video in most scenes. I didn't see any motion artifacts at the lowest level, and fewer artifacts at the highest than with most FI features. You can also turn FI off if you prefer.

Video Optimized Lumens. The Cinema and Reference color presets both offer close to accurate color without any adjustments. Cinema delivering the brighter image of the two, and it doesn't lose any brightness if you adjust it to eliminate the slight blue bias. At 1633 lumens, it is bright enough for a 185" diagonal 16:9 image in a dark room or a 115" image with moderate ambient light.

Presentation Optimized Lumens. The UHZ65 is obviously not designed primarily for presentations, but it can handle them well. Bright mode with default settings is the obvious choice for presentations that don't include photos. Some colors are significantly shifted, but the 2845 lumens can give you a 130" or larger image that can stand up to ambient light.

Low Lamp Modes. The 10 steps in power levels below 100% behave as advertised, lowering the measured brightness by 5% of the full brightness at each step down to 50%.

Zoom Lens effect. The 1.6x zoom lens offers good flexibility for how far you can position the projector from the screen, but with enough loss of brightness to notice. At the full telephoto setting, the lens curtails light by about 23% compared with the wide-angle setting. That's not unusual for a 1.6x zoom lens. But it is enough that for maximum brightness, you'll want the UHZ65 as close to the screen as possible.

Brightness uniformity. The 56% measured brightness uniformity is unusually low a home theater projector. The variation across the screen is easy to see with a solid white image, with the left and right sides obviously not as bright as the broad center swath. Fortunately, most film and video images break up the field of view enough to effectively hide the variation, and the eye will tend to interpret any visible difference as being part of the original image. It helps too that the brightness drops off only near the edges of the screen, where you're least likely to be looking while watching a movie.

Input Lag. Using 1080p content, the input lag with all color modes is 80 ms with FI off and 147 ms with FI on at any setting.

Low Rainbow Activity. With three different movies, I saw rainbow artifacts occasionally in one, less often in another, and exceedingly rarely in a third. Few people, if any, should find them bothersome.

On-Board Stereo. Any projector that costs as much as the UHZ65 pretty much demands being paired with a high quality external sound system. That said, the UHZ65 includes two on-board 4-watt stereo speakers if you need them. Sound quality is on a par with a typical large-screen TV, and the volume is enough to fill a good-size family room.

One minor issue with movies on 1080p Blu-ray discs is that if you jump ahead or back the audio and video fall out of sync with no easy way to match them up again. However, this happened only when I allowed the Blu-ray player to auto connect at 3840x2160 and upscale the image. When I set it to connect at 1080p, and let the UHZ65 upscale the image, the audio and video stayed in sync.

Fan Noise. Optoma rates fan noise at 33dB at 100% power and 29dB at 50%, which makes it a little louder than most home theater projectors. At 100%, you can hear it from 10 feet away at quiet moments as a steady, low-pitched whoosh. But even from 5 feet it will fade into the background for anyone who isn't particularly bothered by noise. At 50% power, the fan noise is low enough that it is unlikely anyone will find it bothersome from 5 feet away.

High Altitude mode, which Optoma recommends using at 5,000 feet and above, is loud enough at all power settings to notice in quiet moments from anywhere in a typical-size home theater. If you need to use High Altitude mode, and particularly if fan noise is one of your pet peeves, consider positioning the projector behind a false wall or behind the screen to help deaden the sound.

Lamp life. The laser-phosphor engine is meant to last the life of the projector. Optoma rates it at 20,000 hours in full brightness mode, and says it should last even longer at lower power settings.

Warranty. The price includes a three-year warranty for the projector, including the light engine, with express advanced exchange.
