PC今晚贴出了W1070的评测，越俎代庖抢在毒版之前先转帖一下，以饷对W1070感兴趣的兄弟们。当然，正式的中文翻译版，还是要等待毒版的大作：

==================================================================================
W1070


W1070，是明基最新的家用视频投影机。原生1080p的分辨率和2000流明的最大亮度输出，可以以原始分辨率观看高清电影，即使在不能完全黑暗的客厅环境下，也有足够的亮度点亮画面。

家庭视频投影机，顾名思义，是用于家庭房间和客厅的综合使用，而不仅仅是只做一个家庭影院。他们可能有较高的亮度输出，内置喇叭的，较为平庸的对比度（在环境光线下，黑位不再那么重要）。与之相反，家庭影院投影机对专用的黑暗观影环境了优化，通常具有非常高的对比度。

----------------------
观看体验
----------------------
W1070默认为动态模式，它的动态模式像其它投影机一样非常明亮，偏绿色。在你需要优先考虑亮度输出，而不是投影的其他其它方面（如对比度和色彩饱和度）时，Dynamic（动态）模式将是合适的选择，因为它付出这些代价以提高整体的亮度。

它还有另外两个模式：标准模式和影院模式。相比动态模式，标准模式和影院模式都具有更好的色彩平衡。标准模式总体色温稍微偏冷。在亮度输出方面，两者大致相同。

总体而言，W1070产生的的图片是明亮而清晰，对于客厅环境是完美的。基于全高清的1920×1080原始分辨率，图像锐利而充满细节；由于高亮度和大的动态范围，暗部细节被保留，除非是在最明亮的环境光线下。

最独特的特性是其3D兼容性，这是通常家用视频投影机上找不到的东西。虽然3D功能肯定吸引了众多投影机买家，但同时满足3D兼容性和实现预定的客厅用途并不容易。这一功能把W1070的用途从白天的家庭娱乐扩展到了夜间的3D观看。

----------------------
主要特点
----------------------
2D图像质量。 W1070并没有很多的附加功能，但是有着非常出色2D图像质量。出厂设置下包含三个完全可用的2D图像模式、3D模式、两个锁定的ISF的模式（供ISF校准后使用）、加上三个用户自定义图像模式。这些模式应对各种家用视频投影机可能会面临的场景，从一个黑暗的影院式的环境，到一个阳光明媚的周日下午的明亮客厅。

3D性能。 W1070采用DLP Link同步全高清3D显示，这意味着图像中穿插了白色的光脉冲（nettle注：AVS的用户反馈是W1070使用了红色光脉冲，而不是白色），以用于与主动快门式3D眼镜同步。这既有好处，也有缺点。一个好处是，DLP-Link系统往往意味着非常低的串扰，W1070在我们的测试中确实没有发现明显的串扰。但另一方面，相比其它红外同步或无线同步的眼镜，DLP-Link的眼镜往往更容易失去同步，比如起身或走动时。不管怎么样，W1070是少数支持全高清3D的家用视频投影机。

有着像样的出厂设置颜色和可敬的对比度，W1070是一个出色的小型家庭娱乐投影机。画面最出色的地方在于天然的图像锐度和清晰度。这不仅是由于投影机的1080p的像素，更是由于它的图像即使是对于高清投影机来说也是像剃刀般锐利 - 尤其是在这个价格范围内。

灯泡寿命长。 W1070的长寿命灯泡，使得它成为一个可以部分替代电视功能的投影。在全功率模式下为3500小时，在Eco/SmartEco的模式下长达6000小时，对比同类投影机的灯泡寿命，这是相当长的时间。这部分是因为W1070启用SmartEco功能后，可以降低最多达70％的灯功率。当投影机显示某些图像时，SmartEco功能将根据画面内容变暗灯泡输出。很不幸，用户并不能自行设置选择亮度，但是当画面并不需要太多光线的时候，这个概念还是有帮助的。

自带喇叭。当家用视频投影机的引人之处是可以替代电视，在被用于这种用途时，往往需要自带的发声装置。 W1070并没有太多的声音系统，它有一个单独的10W扬声器，而不是一些竞争对手提供的立体声音效。但是，一个扬声器不会像小音箱一样容易受到失真或自带特质的困扰。事实上，当音量调大后，这个喇叭对于一个大客厅中的观众来说足够了。

安装灵活性。W1070的手动变焦镜头有一个1.3:1的比例，可以从8英尺4英寸（2.53米）至10英尺11英寸（2.91米）的距离显示一个100英寸对角线图像。对于这一级别的投影来说个很常见的投。不常见的是它的垂直镜头移位，它可以把投影的图像向上或向下移动约10％图像的高度。也就是说，正投的时候，投画面下缘最低与镜头中心线与水平（nettle注：此处有误，画面下缘最低也要比镜头中心高出5%的画面高度），最高可以高出大约20％的图像的高度。这个范围适合于正放在茶几上或者吊装在天花板，而后置搁架安装由于镜头移位和变焦的有限或多或少都有些问题。

6倍速色轮。 W1070有一个6段RGBRGB色轮。这种色轮的布局在尽可能使色彩更加饱满的同时，并没有人为地提高白色的亮度，从而产生了更加自然的色彩。更重要的是，色轮等效六倍速，除了最敏感的那部分观众之外，可以消除绝大多数人的彩虹眼困扰。

----------------------
性能
----------------------
亮度输出。明基W1070产品规格标明了2000流明的最大输出。在动态模式下，将亮度和对比度设到最高后，我们的测试样机测得了2019流明。在出厂缺省设置的Dynamic（动态）模式下，我们的测试样机测得15​​54流明（全功率灯泡）。这是我们在所有可用模式下获得的最大亮度输出，因此大概也是这台投影机的亮度极限。当你需要尽可能高的流明，而不关心颜色的准确度和对比度时，动态模式是一个不错的选择。对于一个准备用于明亮环境光线下的投影，该模式应该会被经常用到。

如前所述，我们最习惯使用的两种模式是标准模式和影院模式。标准模式下测得1271流明，它对客厅环境下的使用尽可能做到了各方面的平衡。它强调亮度，也保持了动态范围，整体灰阶略微偏蓝，产生的色温约7000K。这是一个良好的平衡的影像模式，同时适合电影和视频使用。

影院模式的默认值和标准模式没有太大的不同，我们的测试样机在此模式下测得1220流明和平均6800K的色温。如果你还是觉得太亮（比如当你调暗房间的灯光后），可以使用ECO模式，它减少了近30％的亮度输出，在影院模式下可以产生880流明。

SmartEco模式比较让人困惑。该模式声称可以根据画面内容降低亮度，但实际并不是一个动态的灯泡模式。当该模式开启后，灯泡功率并不会起起落落。事实上，投影机首先根据画面内容，确定所需的灯泡功率，然后锁定在该功率级别进行输出。

对比度和黑位层次。作为家用视频投影机，黑位并不是W1070的关注内容。事实上，相对于家庭影院投影机，甚至同一价格范围内的家用视频投影机，W1070的黑位只能算是平平。然而，这并不意味着投影机的整体对比度弱。即使是在有一定光线的环境下，它的动态范围也足以确保阴影中包含足够丰富的细节。伽马虽然不可调节（只能从预设的列表值中选择，而不能进行单独调整），但还是准确的。如果您发现图像在环境光线下有些平淡，那可以选择一个较高的伽玛设置，使画面更加生动。在低环境光线下，伽马2.4这一设置的效果很出色。

颜色。 关于颜色，W1070有很多地方可以讲。首先，投影机的色彩校准控制范围很广，易于使用。它不仅可以为灰阶校准提供了完整的RGB gain/bias 调整功能，还提供了一个带完整三轴色域调整的色彩管理系统，此外还有ISF模式。其次，也是更重要的，投影出厂设置的颜色就已经饱满和准确，对于低价位的入门投影机来说，这比良好的校准控制更为重要，毕竟只有极少数的W1070的购买者会花费时间和精力来进行校准。

默认模式的校准可以适用于不同的情况。Dynamic（动态）模式，明亮，但是明显偏绿，是用来应对明亮的环境光线。标准模式（色温大约7000K），适用于在中度的环境光线下观看电视和视频。影院模式（色温在6800K），是最接近我们校准的模式，在经过一点点的调整后，就非常适合在夜间看电影。

正如上面提到的，W1070拥有丰富的色彩控制和出色的校准功能。我们的标准过的电影模式中，使用了如下的设置：

Gain
R  3
G -3
B  0

Offset
R -7
G  1
B  9

这些调整将给W1070一个近乎完美的6500K灰阶曲线。

锐度和清晰度。 即使在投影机的对比度控制调低后（默认的设定稍微有点高），W1070依然拥有优秀的原生锐度。虽然没有智能锐化系统或其他细节增强功能，W1070依然能够以剃刀般的锐利和完美的像素精确度显示高清画面中的细节。

输入延迟。通常情况下，3D投影机存在着输入滞后，即使是在使用普通的2D模式时。W1070不一样，它的输入滞后很小，我们的测试下只有24ms（约1.5帧左右）。

限制/不足
2D-3D转换。虽然W1070是全高清3D兼容的，但它不提供2D到3D转换功能。如果2D到3D转换功能对你很重要，请注意这点！

SmartEco。 SmartEco功能本身工作良好：按SmartEco按钮，投影机灯泡输出功率降低。但是，这个功能很难理解，也很难使用。如果你想使投影机进入最经济的设置，你不能从系统菜单中选择设定，而需要选择一些画面使得投影机自动锁定亮度。如果可以调整自己的灯泡功率，那将更为简单，也更容易理解。

镜头位移。事实上，W1070拥有镜头位移，这一点已经领先于大多数竞争对手。但是另一方面，镜头位移的范围很有限，最多只能调整几英寸。调整本身也是很难使用 - 需要使用硬币或螺丝刀来扳动微小的旋钮，而不允许手工转动。因此，虽然已经提供了镜头位移这一本身很受欢迎的功能，但W1070还可以在镜头位移的易用性方面进一步提高。

----------------------
结论
----------------------
明基W1070是一个出色的小型家用视频投影机，生成的2D画面会让人认为这是一款更昂贵的机型所产生。高亮度输出和出色的阴影细节，让W1070可以克服环境光线，而丰富的色彩控制和扎实的出厂校准，让它可以很容易地即插即用。

虽然W1070的黑位和其他家用视频投影机可以一争高下，但是对于在专用全黑影音室中观看电影或照片，它的黑位还不够理想。但是，W1070实现而且非常出色地实现了它的目标，那就是在客厅环境下体验高画质的2D画面，在关闭灯光后欣赏扎实且近乎零串扰的3D画面。最重要的是，它的价格在当今市场上非常具有竞争力。



============================================================================

The newest home video projector from BenQ is called the W1070. Sporting native 1080p resolution and a max light output of 2,000 lumens, the W1070 has the pixels to show HD moves in their native resolution and the power to light up your living room, even if you can't get the space completely dark.

Home video projectors, as the name implies, are designed for multipurpose use in family rooms and living rooms; i.e. places other than a home theater. They are more likely to have higher light output, onboard speakers, and more modest contrast than home theater projectors since black level is less of a concern when ambient light is present. Conversely, home theater projectors are optimized for darkened rooms and typically have very high contrast.

----------------------
The Viewing Experience
----------------------
The W1070 defaults to Dynamic mode, which like other projectors' Dynamic modes is very bright and very green. Dynamic mode will be useful any time you need to prioritize light output over the projector's other qualities, such as contrast and color saturation, as these take a beating in order to increase overall power.

The projector's two other modes are Standard and Cinema. Standard and Cinema modes both have better color balance than Dynamic mode, with Standard intentionally maintaining a slightly colder overall color temperature. In terms of light output, the two are about equal.

As a whole, the picture produced by the W1070 is bright, clear, and perfect for the living room. The picture is sharp and detailed thanks to the W1070's full-HD 1920x1080 native resolution. Thanks to the projector's brightness and solid dynamic range, shadow detail is maintained in all but the brightest ambient light.

Perhaps the most unique quality of the W1070 is 3D compatibility, which is something normally not found on home video projectors. While 3D is certainly appealing to many projector buyers, it is hard to square the W1070's 3D compatibility with its intended use as a living room projector. However this just expands the W1070's potential uses beyond daytime entertainment into night-time 3D.

----------------------
Key Features
----------------------
2D image quality. While the W1070 isn't a projector with a lot of bells or whistles on it, the projector's 2D image quality is excellent. The projector comes out of the box with three perfectly usable 2D image modes, a 3D mode, two locked ISF modes that become available after calibration, plus three User image modes for customization. These modes help the projector cope with the myriad different situations in which a home video projector might be used, from a darkened theater-type environment to a bright living room on a sunny Sunday afternoon.

3D Performance. The W1070 uses the DLP Link system to display Full HD 3D, meaning that the image is punctuated by white light pulses which are used to sync with active shutter 3D glasses. This has both positive and negative consequences. A positive consequence is that DLP-Link systems tend to be very low in crosstalk, and indeed the W1070 had no visible crosstalk during our testing. On the other hand, DLP Link glasses tend to lose synchronization more easily than either infrared-sync or radio-sync glasses, which can be a concern in any environment where people get up and move around. Either way, the W1070 is one of the few home video projectors to feature Full HD 3D.

With decent out-of-the-box color and respectable contrast, the W1070 is a great little projector for entertaining in your home. By far the best part of the image is its natural sharpness and clarity. This isn't just due to the projector's 1080p pixel matrix, either; the W1070 has a razor-sharp image even for an HD projector--especially one in this price range.

Long life. The W1070's long-life lamp makes it an attractive projector to serve as a partial TV replacement. Lamp life is estimated at 3,500 hours in full power mode and up to 6,000 hours in Eco or SmartEco mode, which is considerably longer than comparable projectors. This is in part because the W1070 is capable of reducing lamp power by up to 70% using the projector's SmartEco function, which dims the lamp output to a level appropriate for the content on screen at the time of selection. There's no way to make an arbitrary brightness selection, which is unfortunate, but the concept itself is useful when you don't need a lot of light.

Onboard audio. Part of the allure of home video projectors is their use as TV replacements, and TV replacements need some kind of onboard sound capability. The W1070 doesn't have much of a speaker system; it has a single 10W speaker rather than the stereo sound that some competitors offer. But that one speaker doesn't suffer from distortion or the tinny character that plagues many small speakers. Indeed, with the volume cranked, we found the single speaker more than adequate for an audience of eight in a large living room.

Placement flexibility. The W1070's manual zoom lens has a 1.3:1 ratio, and can display a 100" diagonal image from 8' 4" to 10' 11". That's about standard for this class of projector. What is not standard is the projector's vertical lens shift, which gives you the ability to move the projected image up or down by about 10% of the image's height. The range is such that, at the bottom, the bottom edge of the projected image is level with the lens centerline, and at the top it has an upward throw angle equivalent to roughly 20% of the image's height. This makes table mounting and ceiling mounting the most realistic options, while a rear shelf mount is more or less out of the question both due to lens shift and zoom concerns.

6X Speed Color Wheel. The W1070 has a six-segment color wheel in the theater-optimized RGBRGB configuration. This wheel layout maximizes color without artificially boosting white, and is preferred for its ability to render natural color. What's more, the wheel gives an effective refresh rate of six times per frame. This should eliminate color separation artifacts (rainbows) for all but the most hypersensitive of viewers.

----------------------
Performance
----------------------
Light output. The BenQ W1070 spec sheet states a 2,000 lumen maximum output. Our test sample did indeed measure 2019 lumens, but only in Dynamic mode, and then only after we increased Brightness and Contrast to their maximum limits. In the factory default settings for Dynamic mode, our test unit measured 1554 lumens with the lamp at full power. That's the maximum output we obtained in any usable mode, so it is the practical ceiling for this projector. Dynamic mode is a good choice when you need every lumen the projector can muster and don't much care about what happens to color accuracy and contrast in order to get there. With a projector designed for use in ambient light, that's a situation that will arise from time to time.

As stated earlier, the two modes that we used most often were Standard and Cinema. Standard mode, at 1271 lumens, is balanced for living room use. It emphasizes brightness, but maintains dynamic range and adds a touch of blue to overall grayscale, resulting in a color temperature around 7000K across the board. It's a well-balanced image mode for general film and video use.

Cinema mode, at its defaults, isn't much different; our test unit measures 1220 lumens in this mode at an average 6800K color temperature. If this is too much light (and it may well be once you dim the room lighting), Eco mode reduces light output by nearly 30%, resulting in 880 lumens in Cinema mode.

SmartEco mode is a bit of a puzzle. The mode claims to reduce brightness based on the content on screen, but it is not a dynamic lamp mode. Lamp power does not cycle up and down once SmartEco has been selected. Instead, the projector decides based on the content being shown how bright the lamp should be, and then locks output at that level.

Contrast and black level. As a home video projector, black level is not the W1070's main focus. Indeed, compared to home theater projectors, even HT projectors in the same price range, black level is only so-so. However, that doesn't mean that the projector's overall contrast is weak. Dynamic range is sufficient to maintain excellent separation in shadows, even with ambient light in the room. Gamma, while not as adjustable as we'd like (it uses a list of presets rather than a true adjustment tool), is accurate. If you find the image a touch anemic in ambient light, using a higher gamma setting will give the image some more punch. The 2.4 setting is great in low ambient light.

Color. The W1070 has a lot going for it when it comes to color. First of all, the projector's color calibration controls are extensive and easy to use. It features not only full RGB gain/bias adjustments for grayscale calibration, but also a full three-axis color management system for gamut adjustments -- AND there's a further ISF mode hidden behind a password. Second, and more importantly, the projector has well-saturated, accurate, usable color right out of the box, which in an inexpensive projector is arguably more important than the presence of good calibration controls. After all, relatively few of the W1070's purchasers will spend the time and effort to have it calibrated.

The default calibrations are all appropriate for different situations. Dynamic mode, which is bright and clearly biased towards green, is for combating heavy ambient light. Standard mode, at roughly 7000K, is for television and video in mild to moderate ambient light. Cinema mode, at 6800K, is the closest to a calibrated movie mode, and with a little bit of adjustment is great for night-time movie watching.

As mentioned above, the W1070 has extensive color controls and calibrates very well. Our settings for Cinema mode look like this:

Gain
R        3
G        -3
B        0
Offset
R        -7
G        1
B        9
Those adjustments give the W1070 a near-perfect 6500K grayscale across the board.

Sharpness and clarity. The W1070 has excellent native sharpness, even after the projector's sharpness control has been turned down (it defaults to a setting that is slightly too high). Detail in HD material is displayed with razor-sharp, pixel-perfect precision. And the W1070 does this without a smart sharpening system or other detail enhancement features.

Input lag. Normally, 3D projectors are fairly sluggish when it comes to input lag, even when they are being used in regular 2D mode. The W1070 breaks this pattern and puts up some respectable input lag numbers: around 24ms, or 1.5 frames, in the modes we tested.

Limitations
2D-3D Conversion. While the W1070 is full HD 3D compatible, it cannot do 2D to 3D conversion. If you are looking for a 3D projector and 2D to 3D conversion is important to you, take note.

SmartEco. The SmartEco feature itself works well enough; punch the SmartEco button and the projector reduces lamp output. However, the implementation is hard to understand and can be hard to use. If you want to put the projector into its most economical setting, you can't just select this from a list; you need to put up some kind of content that will cause the projector to select this setting. Being able to choose your own level of lamp power would be far simpler and easier to understand.

Lens shift. The fact that the W1070 has lens shift at all puts it ahead of most of its competitors, which lack the feature. On the other hand, the lens shift range is heavily limited, amounting to a few inches of adjustment. The control itself is difficult to use -- the tiny knob is best turned by a coin or screwdriver rather than by hand. As such, while the presence of lens shift is a welcome feature, the actual ease of use of the control could be improved.

----------------------
Conclusion
----------------------
The BenQ W1070 is a great little home video projector that produces a 2D image that looks more expensive than it is. High light output and great shadow detail help the W1070 stand up to ambient light, while extensive color controls and solid factory calibrations make it easy to just plug and play.

Though black levels are competitive with other home video projectors, they are not at a level where we'd be comfortable recommending the W1070 for dedicated dark room movie viewing or photography presentation. But what the W1070 does, it does very well -- namely, it provides a great living room experience for high-definition 2D content, and with the lights off it can give you a solid 3D picture with almost zero crosstalk. Most importantly, it does all this at a price that's highly competitive in today's market.

大神你好，我是新来的，看回复言语中发现N神是德高望重的人物，想请教一下，W1070和H6510BD好像是比较热门的短焦3D机，都能满足我3.2米投100寸的需求，可是对我来说3D可有可无，但1080P是必须的，有没有哪款机器跟这两款性能相仿但是没有3D功能的，市面上比较容易买到的型号呢，其价格有优势吗？我想如果价格优势不大的话，还不如就要个3D的算了。

不敢当，论坛里面卧虎藏龙，我也只是个入门者而已。

如果要3.2米墙距投100寸的话，2D 1080P里面只有HD86+定焦短镜头可以。如果是3.2米投距的话，大部分主流的2D 1080P都可以，比如HC77-11S/10S、Benq W1200/1100、Viewsonic Pro8200、Epson TW3850C/TW3300C，但是HD20/21、H6500不行。前面提到的这些机子，2D表现和W1070/H6510BD相当或略好一些，价格基本在7000~8000之间，之前HC77-10S京东价格最低到过5499，但是要等促销了。

请教专家，大师，我现在有个困惑，我想在索尼HW50和JVC3800与三菱的747W、787W，这个几个机器里选择，您有什么好的建议，我注重2D，3D无所谓，看过HW50，和JVC3800,这两个比较起来，JVC3800更省一筹，特别是3800的黑位，非常的棒，我以前是个玩三枪的，所以非常喜欢3800的风格，但是现在3800的价格不要3D发射器和眼镜也要18000元，比HW50的15500元要贵近3000元，请问值得吗？还有就是万一不合算，就选HW50的话，画质比三菱的787,比较没有看过，您看如果这两个比，您的建议是什么呢？急切跪求您的建议，谢谢！
