1080p投影机对决:
Panasonic PT-AE3000 vs. Sony VPL-HW10

自从我们发布Sony HW10的评测之后,ProjectorCentral的读者们一直在问这台机器与Panasonic的AE3000相比起来孰高孰低。两台机器都是优秀的家庭影院投影机。两者都提供了具有很高色彩饱和度的华美而鲜明的画面。然而,两者之间有一些区别,这些区别对一些人来说很重要而对另一些人来说并不重要。两台投影机在画质特征上有一些微妙的区别,在功能上有着一些不算细微的差别。让我们一一道来。

流明输出。在两台机器都为呈现最准确的视频图像而进行校准之后,Sony HW10比AE3000稍微更明亮一些。在我们的测试样机上,在为视频显示做了优化之后,HW10测得697流明而AE3000测得566。因此HW10在这个项目上领先。

然而,AE3000的最大流明输出要比HW10高出很多。虽然HW10的视频优化模式高达697流明,然而该投影机无法在此基础上进一步显著地增加亮度。反之,AE3000的Normal(正常)模式在我们的测试样机上测得792流明。Normal模式仍然具有相当好的色彩平衡,因此通过使用这个较明亮的模式,你不必牺牲过多的色彩动态范围。

AE3000还有一个Dynamic(动态)模式,测得1273流明。以将近两倍于HW10的最大亮度输出,AE3000可以被用于在灯光打开时进行视频游戏,或观看高清体育广播节目。确实,有时人们会希望在使用投影机时房间内有一些光线--例如,我有时喜欢在观看电影时吃晚饭。如果房间中有一些环境光线,我就不会那么容易把土豆泥掉在膝盖上。归功于额外的亮度,AE3000比HW10更适合于这种类型的应用。

对比度。就对比度而言,AE3000和HW10完全可以说是半斤八两,但AE3000稍稍占优。我们的AE3000给出了446:1的ANSI对比度读数,而HW10录得416:1。就Full On/Off对比度而言,AE3000标称60000:1而HW10为30000:1。抛开巨大的数字不说,鉴于黑位上的微小变化能够在on/off对比度数据上产生巨大改变,因此实际屏幕上的可见对比度的确存在着一个相当小的差别。

不管怎么说,虽然HW10有非常深的黑位,AE3000仍然要更深一点。AE3000稍微高一点的ANSI对比度与黑位上的增量优势相结合,使其对比度显得比HW10更高一点点。

色彩。出厂设置下,我们的AE3000接近6500K色温标准,虽然色彩确实显得过于饱和。HW10的校准稍微更困难一些,因为我们用于作为校准起点的Medium(中等)色温设置,需要进行一些调整以便更接近6500K标准。在校准之后,两台机器都能够获得平衡度和饱和度俱佳的色彩,尽管HW10为了达到这个效果所进行的工作更为繁重一些。

锐度。Sony HW10和Panasonic AE3000都不如三菱最新的Diamond(钻石)系列投影机HC6500和HC7000那般锐利。HC6500和HC7000是我们今年秋天所评测的所有投影机当中最为锐利的两部机器。然而,HW10和AE3000也绝不是偏柔。当单独欣赏时,它们看起来正如刀锋般锐利,而只有在和三菱机器进行AB对比时,后者才会显示出锐度方面的增量优势。在AE3000和HW10之间,实际锐度差不多是相同的。但由于AE3000在对比度上的微弱优势,就这两台机器而言,AE3000显得更锐利。

数码噪点。当与其它1080p竞争机型相比较时,AE3000和HW10都具有相对较低的数码噪点。两台投影机都具有降噪选项,但即便关闭降噪滤波器,观看起来也仍然令人非常愉快。就噪点瑕疵而言,我们未看到其中一台具有超越另一台的优势。

安装灵活性。AE3000的2.0:1电动变焦和大范围的手动镜头移位(三倍画面高度及两倍画面宽度)是该级别中顶尖的,可以在10到20英尺之间(注:3.05米到6.10米)投出100英寸对角线图像。HW10具有1.6:1手动变焦,可以在10到16英尺之间(注:3.05米到4.88米)投出100英寸对角线图像,而其手动镜头移位为2.4倍画面高度和1.38倍画面宽度,未能达到AE3000的移位范围。

当然,AE3000较长的变焦也具有不利方面。在其变焦的远摄端,AE3000损失了其总亮度输出的41%。因此,如果在视频优化模式,AE3000的566流明会降低到334流明。与此同时,HW10在其最大远摄变焦设置只损失了总亮度输出的22%。这意味着在使用变焦镜头的长焦端时,其视频优化模式的697流明会降低到547流明。因而,虽然AE3000给予你远摄端的更大变焦范围,但随之而来的亮度损失却可能会是你所不愿接受的。

Lens Memory(镜头记忆)。AE3000有一个称为Lens Memory的功能,该功能被设计为通过操作投影机的电动变焦能力,模拟变形镜头的功能。虽然这个概念已经存在很久了,然而AE3000是第一台自动进行该过程并且加入了一键切换的投影机。HW10可以完成同样的功能,但是你将不得不在进行2.35:1和16:9节目切换时完全手动完成设置。如果你对2.35:1超宽屏幕电影不感兴趣,又或者已经拥有了一个变形镜头,那么这个问题无关紧要。然而,如果正你打算搭建2.35屏幕格式,又不想为一个变形镜头买单,那么AE3000给予了你HW10所不能赋予你的至关重要的易用性。

帧插值。本季度最火爆的功能之一就是帧插值。这是一种投影机在视频信号内产生过渡帧从而减少或消除动作颤动的能力(对颤动以及帧插值如何减少或消除颤动的相关讨论,见Evan Powell的这篇文章)。简单地讲,AE3000可以选择激活其"Frame Creation"系统,而HW10则没有这种功能。虽然不是所有人都喜欢帧插值--实际上,一些人认为该功能有悖于"影院体验(胶片感)"--但我们觉得这项功能是自1080p以来家庭影院投影机最为重要的革新。如果你属于那些不喜欢它的人之一,则对于在两台投影机中选择其一,这不算是个问题。

结论

像这篇文章一样的对比评测,常常是吹毛求疵、鸡蛋里面挑骨头。这是因为越来越难以在现今家庭影院投影机上发现明显的缺陷。Sony HW10和Panasonic AE3000都是能够取悦于其用家的优秀家庭影院投影机。HW10的关键优势是,当两台投影机都为理想对比度和色彩性能进行了校准之后,其画面稍微更为明亮。而AE3000的关键优势则是稍高一些的对比度,用于2.35运行的自动化Lens Memory功能,以及可自由选择的机载帧插值功能。哪些功能对你来说更为重要完全取决于你自己。而不论你选择了哪一台,最终你都能在新的家庭影院中能获得美丽的画面。(完)

With the 3000u witch way is brighter , full zoom on a 100'' 16:9 or no zoom with the projector set back more on the same 100'' screen?

Really need help from expert. I have Marantz VP12s2, should I change it to Pana PT-AE 3000 ???

I would love to see a comparison on the Epson 1080u against the new Panasonic is this gonna happen they are priced comparable, Thanks

Gibson,

single chip DLP has A LOT of issues and it is IMO more outdated and flawed than LCD/LCOS.

I am VERY DISAPPOINTED taht these new projectors are not using the revolutionary new invention of LED light instead of bulbs that's already out, and which other companies have already started using. Its actually cheaper to build and operate - there would be ZERO noise practically, no fan system, no bulbs to replace, etc etc. Whats going on???? Why are they still using bulbs and fans?

HW-10 is measured to be much quiter than AE3000 (by a memeber in finnish AV forum). In fact HW-10 was marginally quieter than Mitsubichi HC7000!

AE3000 Eco - 32,7dB Normal - 33,7dB

AE2000 Normal (Colour1) - 31,9 Normal (Normal) - 32,0 Eco (Colour1) - 31,4

Sony VW60 Low - 30,3 High - 31,2

Sony HW10 Low - 29,2 High - 30,5

HC7000: 29,3dB/30,9dB

This comparison doesn't include noise. given how similar the visual quality is, how about some mention of that other important sense.

M. Gibson. The reason we get so many reviews of 3LCD is to show that the so called flaws in 3LCD have been overcome and that pictures are now better than on many DLP projectors. Whats more I expect that unless there a some large price cuts from DLP Manufacures they will start losing market share to the likes of the Panasonic forcing themselves into a "High End - High Price" corner for people with M.M.T.S.

I've heard a 4LCD projector is coming very soon which will answer a lot of the quibbling complaints expressed by videophiliacs here. I dunno how good a movie theatre seems now in comparison to almost any projector. Seating generally isn't ideal, for example, and I recently had to endure a woman loudly laughing through all the philosophical expositions of a film I attended.

M. Gibson - Actually, I own a 3LCD projector. I can sit far enough from the screen to not see minor misconvergence, but I'm very susceptible to single-chip DLP rainbows.

(I'm not the DVD Newsletter Doug Pratt, by the way.)

Mike.

brightness is also effected by how far the projector is placed to the screen and the amount of zoom used. So unless projector reviews had the projecter in the exact same position as projector central then there will be a different measure for brigtness. my guess would be that projector reviews AE3000 was further from the screen which should give higher contrast but less brigtness. (screen gain can also play its part)

What are the comparison between the new pan3000u and the older epson 1080ub

How is it possible that the lumen output in best mode for the ae3000 is so different between the review here and the review on projectorreviews.com. 402 lumens vs 566, that's a pretty significant difference.

The harder it is to tell the difference, the less difference it makes.

Some of you guys have your "discrimination" skills virtually hardwired so that you are convinced that any difference you can find (visibly discernable or not) is a make or break proposition that any fool should be swayed by.

The pictures on these projectors are staggeringly good. Buy either one (or several others reviewed here and elsewhere) for price/service/resale as the primary concerns and you will be grinning like an idiot when you get it fired up on a good screen. I've had a bunch of projectors for the last 25+ years. We are nearing the point of complete practical fungibility.

And that's because: The harder it is to tell the difference, the less difference it makes.

M.Gibson, we're going to continue to get reviews for 1080p 3LCD projectors because it's the only technology available at the $2.5k or less price point. I've owned three 3LCD projectors and while yes, they are not perfect...it's what most of us can afford to have. I've so far have never had any serious problems with panel alignment...maybe I'm lucky. :-) However, I still get rainbow effects from the latest single-chip DLPs.

Let's not sound too elitist by criticizing folks who still value what 3LCD designs have to offer. This site is catering to the J6Ps of projector enthusiasts.

Which of the two projectors has lower fan noise? Although the manufacturer's noise ratings are similar, is one projector actually quieter than the other at close range (my projector needs to sit on a shelf right over my head - so fan noise is a really big deal).

By Sins

Why do you guys keep quoting manufacturers contrast ratings and not your own? I mean you take the time to measure lumens & ANSI but not the full on/off? Are you hiding something or just being lazy?

If you did I would think that would be a plus to the HW10, considering Cine4Home measured 13,000:1 with DI @ D65 on the PT-AE3000 and in Jason's review on AVSForum, he messured 24,353:1 @ D65 on the VPL-HW10.

Thanks for the review Bill...

There is a service menu adjustment for the HW10 to enhance black level reproduction under auto iris. It involves a setting which close down the auto iris fully on a 0% stimulus/IRE gray full field test pattern. Informal contrast ON/OFF contrast measurements with the adjustment indicate the a potential doubling of the manufacturers stated 30K:1 CR potential.

I have documented the service menu adjustment on the AVS forums under my screen name Bytehoven. I invite you to explore the calibration to see if it improves your HW10 black reproduction performance.

Thanks again for your 11/07 HW10 review and the 11/15 HW10 / AE3000 comparison.

Cheers

Doug - you are correct that 3LCD has a lot of problems. I don't know why we keep getting reviews on obviously outdated and flawed technology. And don't even get me started on LCoS (response time 1000 microseconds compared to DLP's 1 microsecond).

What about panel alignment? Hit-or-miss convergence is the one area of 3LCD technology that remains a problem.
