Panasonic的第二代1080p投影机PT-AE2000U,是在去年引人注目的AE1000基础上的一个显著的进步。在一长串优点之中,最为突出的是其杰出的对比度和黑色层次表现。在这两个方面,它胜过了所有其它我们用来进行对比的相同价位的1080p投影机。并且在获得高对比度同时,拥有极佳的色饱和度。以仅仅2699美元的官方价格发售的AE2000是今秋发布的所有新1080p投影机中最为强大和有竞争力的机型之一。

Panasonic PT-AE2000U

关键特点和优势

AE2000突出的特点有一长串,所以很难知道该从哪里开始。正如上面提到的,AE2000最为吸引人的一个优点大概是其黑色层次和动态范围超越了这个价位上所有其它的1080p投影机。在这个方面它只被JVC DLA-RS1所超过,而后者的价格是前者的大约两倍。AE2000由于其优秀的对比度而获得了只能以漂亮来形容的丰富的色彩饱和度――不仅丰富而且准确,因为在预设的电影模式下,色平衡被仔细地调整过。

AE2000具有非常清澈和锐利的图像。总的来说,HD素材的清晰度让人印象深刻到了极致。对于HD图像的锐度和清晰度而言,我们还找不到任何一台能够打败AE2000的竞争机型。对标清信号,图像仍然相当清澈,但SD比HD出现了更多噪点。因此其标清性能,虽然清晰度能够与大部分竞争机型想比,但不是最好的。

AE2000与其上一代机型AE1000是我们所仅见的两台完全没有象素结构的1080P投影机。这归功于SmoothScreen滤镜,一个一直以来Panasonic家庭影院投影机独有的特征。对于那些过去曾经怀疑SmoothScreen滤镜是否会由于消除了象素结构而在锐度上妥协的人(我也是其中之一)而言,答案是确定无疑的"不会"。既然AE2000高清素材的锐度和清晰度超越了其它没有SmoothScreen滤镜的1080p投影机,那么疑虑就可以被打消了。

安装灵活性一直都是Panasonic投影机的特点。该公司是业界第一个在家庭影院投影机中引入2.0x变焦镜头的公司,那是2004年10月的AE700。这一特征在AE2000上继续存在。另外,垂直镜头移位为三倍画面高度,水平镜头移位为几乎两倍画面宽度。因此,你能够在多个不同位置上安装这台投影机,去适应特定的屏幕尺寸和位置。此外,该机还提供了电动变焦和聚焦,从而使得站在屏幕面前用遥控器调整聚焦很容易。垂直和水平镜头移位是手动的。

风扇噪音非常低――在全功率模式下也仅仅是耳语般可闻。即使在高亮度模式下,当风扇在排放额外的空气来补偿时,这部机器仍然是极其安静。在经济模式下,风扇以任何标准而言都是安静的――除非把耳朵靠得很近,否则你感觉不到它的运转。

一个最为有趣的新功能是分屏调整,一项我们从未在家庭影院投影机上见过的技术。下面是其使用方法。以一帧你想作为模版的屏幕图像开始,像下面这样…

在你定格想要的这帧之后,简单地激活分屏选项,一个矩形选择窗口会弹出来。你可以左右移动这个窗口来定义你想具体调整的图像的某一部分。

一旦选定了想要的部分,投影机将会复制该部分,这样就会得到两个并列的完全相同的拷贝。

现在你可以进行任何想做的调整,包括色温,色饱和度,亮度,对比度,gamma曲线。投影机将对屏幕右侧的图像做出调整,同时保持左侧的图像不变。用这种方式,你能够真切地看到你所做改动的效果。你可以选择保存或者放弃试验的改动。对于许多用户来说,这是一个很好的教学工具,用于理解投影机所提供的各种调整选项的本质及其调整范围。

对于亮度,AE2000有相当多的选择。预设的视频优化模式中,影院1,2和3色彩平衡并且具有理想的视频表现。它们在gamma和色温上有所区别,但亮度基本一致。在我们的测试样机上,分别测得345,390和370 ANSI流明。三者之中,我们选择影院1模式作为大多数评测项目的观看模式。

如果你想要更多亮度,正常模式将会给你一个亮得多的图像。正常模式在样机上测得超过900 ANSI流明。色平衡没有在影院模式下好,但仍然是让人惊讶地令人满意――色彩稍微有些偏冷,是的,但并不是像其它大多数投影机一样:冰冷,或者是令人不安的绿。一般来说,加大亮度输出到最高亮度设置会导致色彩向蓝绿偏移,从而使得画面不再令人感到舒适。

一旦在正常模式下应用缺省的色温之后,你可以降低色温从而对偏冷的图像加以补偿。仅使用色温控制,你就可以逐步地使图像变暖,同时逐步降低流明输出。在最暖的设置下,仍然可以获得非常实在的600流明。底线是,AE2000提供了一个范围很大的流明输出的可用选项集,因此你可以选择一个来满足在流明输出,品位喜好,屏幕尺寸,遮光条件以及其他方面的需求。

虽然最纯粹的视频发烧友会选择影院模式,我们肯定许多烧友也会把正常模式作为一个非常有吸引力的备选模式。以一丁点儿色彩准确度为代价换来大很多的流明输出,将是一个值得的妥协。在正常模式下,加以些许调整,你就能得到明亮的,高对比度的画面,同时具有丰富的色饱和度以及不会偏蓝、偏绿的真实的色彩。

最后,对于那些有兴趣用变形镜头设置2.35:1屏幕的用户而言,AE2000有一个合适的变形垂直延伸模式,用来配合变形镜头。

局限

在这台机上找到一个可以加以抱怨的地方还真不容易。当然,对于想吊装投影机的人来说,如果可以选择白色外观就更好了。确实,当吊装在客厅或起居室的白色天花板上时,AE2000的暗灰色外观在审美上不是那么令人愉快。然而,在专用视听室里,AE2000就不会那么显眼了。

机载480i信号的逐行扫描还不错,但是也不算很好。用HQV测试模版,旋转的条纹看上去很清晰,但在飘扬的旗帜上却可以发现相当多的逐行扫描瑕疵。对于跑道场景,AE2000看上去相当好,在看台上没有出现任何摩尔纹。但在电影/视频片段中,滚动的演职员表呈现出太多的jitter和不稳定性。总的来说,有好有坏。

另一个值得考虑的局限是假如使用影院模式,亮度输出将会限制屏幕的尺寸。在没有环境光线的黑暗房间中,影院1模式在100到106寸的屏幕尺寸之间表现最好(我们使用的屏幕为120寸、增益0.95的Stewart Grayhawk)。一旦放大到120寸,将失去足够多的饱和度和亮度,使得我们想要减小图像尺寸或者选择正常模式。这是镜头为广角(最短投距)的情况。将投影机拉远,使用镜头的长焦部分将会显著地使画面变暗。在最远投影距离上,亮度输出比广角设置时低大约40%。因此对于打算使用AE2000的影院模式的视频发烧友,最重要的是要在屏幕大小和投影距离之间做出妥协。尽量缩短投影机到屏幕的距离,并且为了尽可能最佳的画面,除非使用高增益屏幕,不要超过110寸。

如果选择运行正常模式来获得更高的流明输出,你可以把投影尺寸扩大到150寸或者150寸以上。对所有投影机来说,图像大小和图像质量一直都是鱼与熊掌不可得兼。增大图像尺寸就会失去有效的对比度和色饱和度。有趣的是,AE2000能够使你在不牺牲太多色平衡和色彩饱和度的情况下获得更大的图像,而这种牺牲,对于绝大多数其它你能见到的投影机来说,都是无法避免的。

竞争机型

Panasonic AE2000 vs. Sanyo Z2000

这场Panasonic AE2000和Sanyo Z2000之间势均力敌的对决,比较了两台1080p LCD投影机,两者都具有大量优点和激进的价格。显著的区别如下:

1. AE2000具有更高对比度,更好的黑色层次以及更佳的色饱和度。我曾在Z2000的评测中指出这个区别在较小图像尺寸时极为突出,而在120寸屏幕上就没有这么突出了。虽然这是事实,但是在较大图像尺寸时,AE2000相对Z2000的优势仍然是可见的。其中一部分取决于用户选择的调整设置。但总的来说,AE2000在对比度表现上的优势比你从对比度指标(16,000:1对15,000:1)上能够想象到的更明显。

2. AE2000在流明输出上也有优势。AE2000预设的影院模式(具有最精准的色彩因此对于视频发烧友而言最具吸引力)测得亮度在345到390流明之间。正常模式下,流明在600到930之间,因用户对色温设定的喜好不同而变化。但即使在930流明时,我们也没有感觉到画面像在其它投影机高亮度模式下那样会冷得过分。

同时,Z2000预设的影院模式(纯影院模式和生动影院模式)测得230到260流明之间。虽然这两种模式是有吸引力的设置,但它们最适合用于80到90寸的较小的屏幕上。Z2000的明亮影院模式测得550流明,对于预设设置而言可算是最实际的选择。明亮影院模式呈现相当好的色平衡,其明亮的图像可以在黑暗房间中投满120寸。然而,它没有AE2000在正常模式下所具有的动态范围和黑色层次。你可以仔细调教Z2000的用户选项以获得在大约400 ANSI流明下的优秀的色彩平衡,但是,无论怎样努力也不能调出AE2000从黑到白的全部范围。在最亮的设置下,Z2000能够产生1000流明以上,但明显失去了色平衡,因此对视频欣赏不会是一个有吸引力的选项。

3. AE2000没有任何的象素结构,而Z2000在足够近的地方观看时有精细而清楚的象素结构。在超过一个屏幕宽度的观看距离上,两台投影机都没有表现出任何纱窗效应。

4. AE2000和Z2000在HD素材上都拥有杰出的图像清晰度。在现实中,AE2000由于其更高的对比度和饱和度,而在高清晰素材的清晰度上超过Z2000一点点。然而,Z2000在标准清晰度素材上有更多的优势,比AE2000更加顺滑、干净,更少噪点。在两机对比观看Lewis Black的DVD"Black on Broadway"时,我们的眼睛不停地被Z2000引人注目的电影般的画面所吸引。标清DVD的清晰度是Z2000让人印象最深刻的特征之一。

5. AE2000拥有电动的变焦/聚焦,而Z2000是手动的。两者都是手动镜头移位。对从一个固定位置将图像投在16:9屏幕上来设置投影机的人来说,电动变焦/聚焦是很便利,但是一旦投影机设置好之后就不怎么用到了。因此在这种情况下,电动变焦/聚焦是一个不太重要的功能。另一方面,如果你设置一个4:3的屏幕,并且想通过前后变焦来使16:9和4:3的素材都能投满屏幕尺寸所允许的最大面积,那么,电动变焦/聚焦是极为有用的。类似地,如果你计划安装一个2.35宽屏幕,对于2.35电影你可以使用AE2000的电动变焦增加尺寸使其填满屏幕,而对于1.78(16:9)的素材,你可以通过变焦减小其尺寸使其在垂直方向填满2.35的屏幕。用Z2000可以完成同样的事情,但你必须手动调整镜头,这意味着你要能容易地调整投影机才行。如果投影机是吊装的,这样做就不切实际了。

6. 如果你想安装一个2.35屏幕并且用一个变形镜头来维持一个固定的图像高度,AE2000有垂直延伸模式来配合这种镜头,而Z2000没有。

7. 两台投影机都能接收1080p/24信号。AE2000以96Hz刷新率显示24帧信号。在本文写作之时我们还不知道Z2000对24fps信号的刷新率。但是,只要是24Hz的整数倍,在感觉上就不会有区别,因为LCD将维持一个固定的状态,直到来自下一帧胶片的信息将其替换。在实际运行中,当以1080p/24信号作为输入时,相比1080p/60信号,两台投影机的运动场景的颤动都明显减少了。

8. AE2000有着简朴的,暗色调的工业外观设计,反之Z2000的洁白的外观很可能吸引大多数消费者的眼球。我猜测,如果你是一个想要说服老婆在客厅天花板上吊装投影机的男性,她很可能比起AE2000更喜欢Z2000的样子(对这个我会搞错也说不定--预测女性的喜好从来就不是我的强项)。另一方面,如果你在后墙的书架上安装投影机,那么AE2000较暗的外壳颜色将会使它与四周融为一体,不会成为房间里的一个显眼的东西。

9. AE2000有16个用户可编程设置,Z2000有7个。两台投影机都允许你通过重命名你自己的设置来获得更好的标识,而不仅仅是只能通过数字来记住它们。然而除此之外,Sanyo Z2000还能让你重命名输入端,因此,在菜单上不再是"HDMI 1,HDMI 2, Component Video",你能够重命名这些端口,比如,"HD DVD,Playstation 3,DirecTV"或者任何你可能连接到那些输入端口的信号源。AE2000没有提供重命名信号源输入端口的能力。

10. AE2000有一些Z2000没有的功能。分屏调整功能对于AE2000来说是独一无二的,另外还有一个可以用来辅助调整的机载波形监视器。AE2000有3个HDMI端子,而Z2000有两个。AE2000的遥控器有一些通用能力,允许其学习并控制影院中的其它几样设备。而Z2000的遥控器更加传统一点。

目前Z2000的价格在打折之后为2,195美元,AE2000为2,699美元。Z2000的较低价格包括一个3年的使用保证,AE2000拥有1年使用保证,以及目前购买可以获赠的额外一年使用保证。在我们的评测中,两台投影机都代表了杰出的价值。对于有额外的钞票的人来说,AE2000因为其对比度,饱和度,流明性能而对得起多付的钱。但如果你的片源是标清、高清都有,而你又打算欣赏大量的DVD的话,则Z2000有着卓越的价值,其DVD素材极为平滑的图像确实引人注目。

结论

PT-AE2000U的问世,使得Panasonic在家庭影院投影机的世界中又推出了一个闪闪发光的机型。它在对比度和色饱和度上远超其它竞争对手。它拥有视频优化模式下极好的色彩准确性,以及一个超级好用的明亮运行模式,这个模式使得用户以极少的色彩准确度为代价获得明亮的图像。特别对于HD DVD,蓝光,以及HDTV信号源,AE2000是目前为止我们曾见过的5,000美元以下的1080p投影机中最强大的一台。并且因为它仅为2,699美元,它代表了目前高度竞争的1080p投影机市场上的最佳性价比。

在我们能够评测完所有1080p型号之前,我们暂时保留5星评级的颁发。但是从我们已经看到的来讲,我们能够肯定AE2000将获得非常高的评级。(完)

I have one with 400 hours on the bulb, but it has developed an annoying flicker. The light just pulses and returns to normal. I had been running it in Eco-Mode for the first 350 hours when it started to happen but I read on a forum that running in Eco-Mode can damage the bulb resulting in this effect. Don't know how true it is but for all you other owners who have not experienced this yet it's might be worth looking into.

One other issue with the PT-AE2000. I'm not sure it's my unit or it's the same for all units.

When you turn the unit off, you can hear the lens moving back. And when you turn it on, the lens go back to its earlier position.

On my unit, after a few off/on cycles, the focus will be slightly off and will require re-adjustments.

I believe this is related to my previous comment that you can't not control the auto-focus very accurately as the steps between each settings are too big.

Today, temperature reached 42 degres celsius outside (107.6F), my cinema room was rather cool. After a 2 hours movie, the temperature was unbearable. The Panasonic pumps too much hot air. This is the #1 problem with this unit...

Picture wise, it is a fantastic machine

Reply about: "How do these function buttons work? Are you able to teach a learning remote discrete input codes?

btw, I wish reviewers would pay more attention to the availability of discrete codes. Sanyo is much better than Panasonic in this regard"

The remote has three buttons at the top. You can assign a specific function to one of the buttons. Like HDMI1, HDMI2 , Set Focus etc... Then using the logitech I just learnt the code for those 3 buttons.

"Remote control. Something very annoying with the Panasonic remote is that you do not have discrete IR codes to go to all different kind of inputs. Say you want to go to HDMI2, you have to cycle through all inputs until you get on HDMI2. Very annoying if using say a Logitech Harmony remote as often the input on the projector won't be correctly set after running a macro. The AE2000 has an edge over the AE900 as you can define 3 buttons to be whatever you want. But that's not enough with so many inputs (I'd like 2 more, so I get with the press of one button: HDMI1, HDMI2, HDMI3, Component, Video, VGA)"

How do these function buttons work? Are you able to teach a learning remote discrete input codes?

Here are my comments about the projector.

I bought mine two weeks ago and I've had it setup last week... It is in replacement of a Panasonic PT-AE900.

Picture quality is very impressive compare to the AE900. Especially with HD materials like blueray or hd-dvd. But I found that even my average DivX TV recordings looked better.

I will pass on everything that I find great as it's been commented on already.

My comments so far:

Heat: The AE2000 pump a lot of hot air ! it increases very rapidly the temperature of my room by a few degrees (room is 4.8m x 3.5m * 2.8m high). It's getting warmer here in Oz (it's summer here) and it's going to be an issue soon.

Noise: The AE2000 is significantly louder than the PT-AE900, I can hear the projector over my xbox 360 ! it's rather annoying when watching a dialog scene. I'm quite surprised here as most reviews mentioned how this projector was virtually silent. I had a listen in another store and it was producing the same level of noise, so it's definitely not my unit.

Low light vs normal: Well, other than the fan is a bit quieter in low output mode, I can't tell the difference between normal and low. the difference in the AE900 was significant.

Picture is very bright (lumen-wise), in fact the whites are somewhat hard to watch (I use Cinema 1 settings). It could be that I'm just so used to the AE900 picture which was definitely not as bright. Whites sometimes make me frown.

Remote control. Something very annoying with the Panasonic remote is that you do not have discrete IR codes to go to all different kind of inputs. Say you want to go to HDMI2, you have to cycle through all inputs until you get on HDMI2. Very annoying if using say a Logitech Harmony remote as often the input on the projector won't be correctly set after running a macro. The AE2000 has an edge over the AE900 as you can define 3 buttons to be whatever you want. But that's not enough with so many inputs (I'd like 2 more, so I get with the press of one button: HDMI1, HDMI2, HDMI3, Component, Video, VGA)

Moving pictures: There is a slight blur when you have a traveling scene. All the reviews talk a lot about the quality of the picture, with still shots etc... none of them talk about what it looks like in what the projector is mainly used for: movies !! The blur effect is far more noticeable than the AE900 which was perfect there. I am not sure it's a side-effect of having such high resolution, the movie I was watching (Transformer HD-DVD) or my eyes :) but it's an annoying effect

Manuals: they are crap. The PT-AE2000 is extremely feature rich, none of those features are well-explained. Pretty much nothing on how to use the waveform screen nor is there a chapter on how to best set the projector.

motorised zoom and focus: While it's extremely convenient to be able to stand next to the screen while setting the focus, I do believe now that you can achieve better result with a manual one. The various steps aren't that progressive. Say you press 5 times the focus+ on the remote and again 5 times on focus- you won't be back where you started. The jumps between 2 changes is too high and in my case I've always felt that the perfect focus is right between two settings. It took me a fair while to get the perfect focus, it would have been much faster with a manual one.

That is all for now. Cheers Jean-Yves

How does the bightness and contrast, black/white levels and sharpness of this projector compare to the PT-AX200 and Sanyo PLV-Z5.

I know they're 720p but resolution is not as important to me as is the brightness/contrast/sharpness etc.
