ERLAUTERUNG:Acer h7850 handbuch
This projector uses the 0. In addition to x resolution, it offers HDR and a rated 1, contrast ratio. Moreover, it is ISF certified, so if you get it calibrated by an ISF technician, the choices for color modes will include ISF Day and ISF Night.
For SDR material, the H delivers appropriately fine detail for the resolution, color well within a realistic-looking range, dark blacks, and excellent contrast and three dimensionality. With HDR material it loses enough shadow detail in dark scenes to notice, but still delivers a compelling picture. Setup conveniences include the 1. In addition, it is only Another key strength is that the H is bright enough to fill very large screens.
Even with optimized settings for video, it can light up a " 1. For brighter rooms or larger screens, it can deliver a quite usable image with enough brightness to boost the screen size to as much as " in a dark room or " with moderate light. Acer H Performance Brightness. Acer rates the H at lumens. We measured ANSI Lumens for our test sample with the zoom lens at its widest angle setting as follows in full power and Eco On modes: Acer H ANSI Lumens MODE Full Lamp Eco Mode Bright Standard Movie Dark Cin.
The specs also mention ExtremeEco, which isn't an Eco setting, but a power saving feature. According to Acer, if the projector doesn't detect a signal, it will shift to Eco lamp mode. Zoom Lens Light Loss. The 1. That's not unusual for this level of zoom, but it is enough to notice. For maximum brightness, you'll want to position the H as close to the screen as possible for the screen size.
Video Optimized Lumens SDR. Movie mode with some slight tweaking gives the closest color match to our reference projector and no loss of brightness. Even with default settings, colors are nicely saturated and well within the realm of realistic; they are slightly blue shifted compared to a reference projector, but not enough to be noticeable. The H also delivers good shadow detail as well as excellent contrast, three dimensionality, and black levels.
Compared with the Optoma UHD60, for example, its black is ever so slightly darker, but by so little that the difference shows only in a side-by-side comparison. In a dark room, the measured lumens with video optimized settings can give you a bigger picture than you might have room for. It is enough to light up a 1. Switching to Eco power mode, at ANSI lumens, drops the sizes to " and ", and also lets you move to Normal power mode as the lamp ages and loses brightness.
For rooms with ambient light, the brightness in Normal power mode with video optimized settings is enough for a 1. For higher ambient light levels or larger screens, you'll need to use a brighter color preset mode. Color Preset Mode Performance. The H delivers realistic-enough looking color and good enough contrast in most modes to be highly watchable even with default settings. As with many projectors, the exception is its brightest mode, which has an obvious yellowish-green bias.
If you need the extra brightness however--to stand up to bright sunlight in a family room for example--you may be willing to use it on an occasional basis. Standard, the second brightest mode, has a slight blue shift, which most people find more acceptable than a green shift. In this case, the colors are well within the realm of realistic looking. However, Standard mode has lower contrast than Movie mode and appears slightly less three dimensional.
Dark Cinema delivers a close color match to Movie mode, but with a different gamma setting that improves shadow detail separation just a touch, while lowering contrast in most scenes that aren't dark enough for shadow detail to matter. Game mode and Sports mode are similar to Dark Cinema, but with higher brightness. Silent mode is similar to Movie mode for color, but somewhat brighter with its one power setting than Movie mode with Eco On.
Video Performance. The H delivers solid video performance for the price. In addition to realistic color, dark blacks, and excellent contrast and three dimensionality with SDR input, it delivers appropriately fine detail for both native UHD and upscaled p input. For even crisper images, it offers both Super Resolution and Sharpness settings that you can adjust to taste. If you crank them up too high, however, they will make minor skin imperfections look like a nasty rash. Video processing options also include AcuMotion--Acer's name for frame interpolation FI --with four settings, including Off.
Even level 1 smooths motion almost entirely and removes judder from camera pans, but it also adds a noticeable digital video effect to film. If you find that bothersome, you might want to use it only for live and recorded video, including sports, where you're much more likely to consider it an enhancement. Like most DLP projectors, the H shows occasional rainbow artifacts.
In my tests, the only times I saw them often enough to be bothersome were in test clips chosen specifically because they tend to show rainbow artifacts. Unless you're particularly sensitive to them, they shouldn't be an issue. HDR Performance. The H offers four HDR settings. Level 1 is closest to the spec, but far too dark--losing most shadow detail in dark scenes. Level 4 is the brightest and most watchable. For optimal viewing, I started with Level 4, changed the gamma setting, and adjusted color to remove a noticeably green bias.
After the changes, the H delivered a compelling image. The more important limitation for HDR with the H is that it offers only one User mode, and any changes you make to the factory default settings in any preset color mode immediately get saved in User mode, and erase whatever was there before.
So you are required to use the factory default settings for all color preset modes and reserve User mode for HDR, unless you want to recalibrate your preferred custom settings every time you switch between HDR and SDR. It is simply more work than you should have to do. Brightness uniformity. With a solid white image, it is obviously brighter in the center than the sides and brighter at the bottom than the top.
With film or video, the difference is much harder to see. Depending on how much low uniformity bothers you, you may consider this unacceptable at this price or may never notice it. On-board audio. Home theater projectors are normally used with external sound systems.
But if you need the H's onboard audio, the two 5-watt stereo speakers deliver good sound quality and enough volume to fill a small room. Fan noise. Acer rates the H at 26 dB in full power mode, 24 dB in Eco mode, and 19 dB with the Silent color preset. In quiet moments, you can hear the fan in both full power and Eco modes from anywhere in a mid-size room as a steady white noise. Both have a high-pitched overtone that makes them more noticeable than they otherwise would be, but Eco mode is quiet enough that it shouldn't bother most users.
Silent mode eliminates the high-pitch component entirely and is quieter still, making it hard to hear from more than a foot or two away. Acer recommends using High Altitude mode at 5, feet and above. If you plan to run in full lamp mode at High Altitude you may want to consider setting the projector up with some sound deadening material around it. Input lag. The 77 to 80 ms input lag with FI off, and the even slower ms with it on, makes the H a poor choice for serious gamers.
More casual users may find it adequate with FI off. Connection Panel Inputs: 1 LAN 1 RS control 1 HDMI 1. Setting up the Acer H Throw Distance. The H's throw distance for a " image ranges from about 12'2" to 19'4". To find the throw distance range for the image size you want, see the Acer H Projection Calculator.
Lens offset. This range is ideal for setting up the projector on a low table or inverted in a ceiling mount. There is no keystone adjustment to square off the image, which means you should avoid any situation that forces you to tilt the projector up or down to hit the screen. This effectively rules out options like putting it on a high shelf behind the seats, which will usually force you to tilt it downward. Competitive Comparison: Acer H vs.
Optoma UHD60 When comparing the Acer H and the Optoma UHD60we find that each has some advantages over the other. The H is the brighter of the two but not by much. The H's brightest mode measures ANSI lumens compared with for the UHD Its Movie and Dark Cinema modes are both about lumens compared with for the UHD60's Cinema mode.
The UHD60 test unit had a persistent flicker in Eco mode. We saw a similar flicker with the H when connected to a computer, but not with a Blu-ray player or FiOS, which makes it irrelevant for home theater use. SDR Image Quality. For SDR input the two projectors are a nearly even match for almost every aspect of image quality, with suitably neutral color, excellent contrast and shadow detail separation, and dark blacks. The H's black is slightly darker, but by so little you can't see the difference without a side-by-side comparison.
HDR Image Quality. For HDR input the UHD60 has a significant advantage for holding shadow details, showing details in dark scenes that get lost with the H The H also adds digital noise in some scenes and shows rainbow artifacts a bit more frequently than the UHDtwo issues that did not show up with SDR input.
The biggest advantage for the UHD60 for HDR is that it lets you easily maintain separate settings for HDR and SDR input without the risk of overwriting your customizations. With the H, you can define User mode for HDR, but as soon as you, say, tweak Movie mode for better color accuracy, the tweaked version becomes the User mode and the HDR settings are gone.
