Projector key points review regarding this projector.
Performance
Light output. The Acer H6510BD is bright. At its brightest, in fact, our test sample measured 2524 ANSI lumens with the lamp at full power. Even eco-lamp mode, with its extended lamp life, puts out 1856 lumens in Bright mode -- 74% of full power output. Bright mode's color is undersaturated and pushes blue/green, while black level suffers, but Bright mode can be useful in a room with high ambient light where those factors matter less than pure output.
Standard mode, which has a more balanced image than Bright mode, produces 1844 lumens with the lamp at full power. Standard mode's black level and shadow detail are better than Bright mode, while color shows less of a blue push though green is still overdriven.
By default, Movie mode is the projector's best film and video mode. At 1336 lumens with the lamp at full power, Movie mode has the best default white balance of any mode, though it is still several hundred degrees off from 6500K. Our final calibration for film and video used Movie mode as a starting point and measured almost exactly 1300 lumens post-calibration. In a darkened theater, that is more than enough to drive even the largest screens up to 140" diagonal and above. But the H6510BD really shines in a room with some ambient light, where that extra lumen output can help defeat ambient light and still produce a bright, satisfying picture.
While none of the pre-calibrated image modes are appropriate for large screens, you can also reduce light output by 52% by disabling BrilliantColor in the projector's Advanced menu. If you have a small screen and a light-controlled room, this can help bring the projector's brightness in line with your needs.
Contrast. The H6510BD's black level is deep enough to create a satisfying picture. However, this does not mean that it is the equal of projectors many times more expensive, which benefit from better internal light control, auto iris systems, and higher-contrast chips. Black level is comparable to other entry-level 1080p projectors. Shadow detail is well-defined, and deep shadows in the very low range are still rendered cleanly.
Color. The H6510BD has three preset color temperature settings: CT1, CT2, and CT3. CT2, which is the default in Movie mode, is the most accurate of the three, but red is still under-emphasized while green is pushed. Folks who don't mind fine-tuning their projectors will want to switch to User mode and make adjustments from there.
Limitations
Color. While grayscale on the H6510BD can be calibrated to near 6500K, the projector still has some color problems. First and foremost, the projector's color gamut is nowhere near the Rec.709 recommendation. This means that while the relative levels of red, green, and blue in an image may be balanced correctly, the projector has a different idea of what constitutes, for example, "green" than the source material does. Color gamut is notoriously difficult to calibrate without the proper equipment, and it is important that low-cost projectors have accurate gamuts whenever possible as most buyers of the H6510BD will not want to spend the money or time to calibrate the projector properly.
What's more, the H6510BD has low color brightness. Color brightness or Color Light Output (sometimes abbreviated CLO) is a measure of a display's ability to produce colored light. The standard addresses the problem of a projector producing much more white light than colored light, which is helpful in certain circumstances but can be actively harmful in others. Our test unit measured color light output at only 47% of white light output when BrilliantColor is enabled. Disabling BrilliantColor reduces white light output such that white light output (WLO) and CLO are equal, but as you might imagine that kills most of the H6510BD's white light lumens.
You should care about color light output for a few reasons. First of all, a large imbalance between WLO and CLO causes the image to look unbalanced and changes your perception of color. Next to a super-bright white, color tends to look dull, dreary, and undersaturated. When you're trying to produce a well-balanced cinema image, the brightness differential can be detrimental.
No VESA port. Some DLP Link projectors have the ability to switch to IR sync by using an external emitter. Since the H6510BD lacks a VESA port, you're locked into DLP Link for the life of the projector. It also makes it difficult, if not impossible, to connect 3D accessories, as they tend to use the VESA standard. Then again, few of the H6510BD's competitors include a VESA port, either.
Color wheel. With a six-segment RGBCMY color wheel spinning at 7200RPM, the H6510BD has a 2X-speed color wheel. This means those sensitive to rainbows will see them in droves. As there are other projectors around this price range with faster color wheels, the H6510BD could be a poor choice for anyone with a known sensitivity to color separation artifacts.
3D flicker. The Acer H6510BD runs at a 96Hz refresh rate, which is low for a 3D projector. This means that users sensitive to 3D flicker will tend to see more of it on the H6510BD than on a projector with a higher refresh rate. If you plan to watch a lot of 3D content, this could be an important criterion for your decision.
No customization of image presets. The H6510BD has a number of pre-calibrated image modes, but those modes cannot be altered. Instead, when you select an image mode and make an adjustment, the projector pushes your settings over to the User option where you can make further adjustments. As the projector only has one User memory, that means you can only save one group of settings.
This can be problematic depending on how you want to use the projector. For example, color calibrations when BrilliantColor is off are wildly different from color calibrations with BrilliantColor on. BC off looks smoother and more natural, but BC on provides much more white light output. If you use your H6510 in a dual-use capacity as both theater and living room projector, it would be helpful to retain both sets of calibrations without having to manually input them every time.
Brightness uniformity. Our test sample showed noticeable dimming in the corners of the image. The dimmest corner (top left on our projector) was only 65% as bright as the image's center. This is most evident on a solid white screen, but it can manifest when watching film and video as well. It is also possible that this was a problem only on our test sample and other samples will not display this flaw.
Shootout: Acer H6510BD versus BenQ W1070
The Acer H6510BD's closest competitor is the BenQ W1070. Both projectors are native 1080p, DLP-based, and have full 3D compatibility. Both have dual HDMI ports, 1.3:1 manual zoom lenses, and long-life lamps. So what sets these two projectors apart?
Image quality. Despite similar specifications, the images from the H6510BD and W1070 are very different in their character. Both projectors produce similar amounts of light and have similar black levels, but the W1070 produces a smoother, more balanced, more natural-looking image than the H6510BD. Color is more accurate and better saturated on the W1070. In images with strong highlights, the W1070 does not have the screaming-bright whites of the H6510BD, which makes it look more like reality. If video quality is a primary concern, the W1070 has several distinct advantages.
3D. The W1070 has a qualitative advantage when it comes to 3D. While the H6510BD is brighter by far, the W1070 has the advantage of a faster refresh rate. By refreshing at 144 Hz to the H6510BD's 96 Hz, the W1070 shows less flicker and a smoother overall picture. Neither projector has a crosstalk problem, largely due to the fact that DLP Link is not especially prone to crosstalk.
Brightness. Both projectors' calibrated modes measure somewhere in the neighborhood of 1300 lumens. The H6510BD has a brighter maximum output, at 2524 to the W1070's 1554, so users looking for a living-room projector might want to take that into consideration.
Contrast. The W1070 and H6510BD have similar black levels, and both render shadow detail well, so contrast is effectively a tie.
Color. The W1070 has a distinct advantage when it comes to color. Not only does the projector's better saturated, more accurate color give it a clear advantage in HD content, but it also has more accurate color straight out of the box for users who don't want to fiddle around in the menus. Both projectors can be calibrated to 6500K grayscale, but the W1070's more accurate gamma and better saturation give it an edge even so.
Rainbows. The W1070's 4x-speed RGBRGB wheel shows significantly fewer rainbows than the H6510BD's 2x-speed RGBCMY wheel. If you are sensitive to rainbows, that's worth considering.
Features. The W1070 has a small amount of vertical lens shift while the H6510BD has none. On the other hand, the H6510BD has 2D to 3D conversion while the W1070 does not. The H6510BD's lamp life is slightly longer, while its fan is quieter.
Conclusion
The Acer H6510BD may be the most affordable full 3D projector available today. At $799, it delivers an attractive image that's great for high-definition films and video in either a darkened theater or a living room.
While the W1070 has advantages over the H6510BD in several important areas, it also costs about 20% more than the H6510BD. Neither projector comes with 3D glasses, but both use inexpensive DLP Link eyewear rather than a proprietary solution. These days, especially when working with entry-level projectors, that $200 gap can be important to some people. As always, it is up to the user to determine whether the additional image quality is worth the extra money.
