Sanyo PLV-Z700
1080p 家庭影院投影机

去年我们曾经说过PLV-Z2000是Sanyo迄今制造的最吸引人的家庭影院投影机。新近发布的Sanyo PLV-Z700,该公司最新的1080p投影机,使用了和Z2000相同的设计,即完全一样的外观,色泽,以及连接面板。除了型号标签之外,你无法从外观上区别两台机器。

凭借Z700,Sanyo延续了其发售定价激进的高性价比家庭影院投影机的传统。这是第一台上市零售价格低于2000美元的1080p解像度家庭影院投影机型号,而真正的市场价格还会大大低于2000美元。

Z700和Z2000之间的区别如下:

oZ700因为使用有机LCD面板而具有较低一点的对比度。相比之下Z2000使用了无机面板。
o不同的物理光圈机构。
oHDMI版本从1.3a升级到1.3b。
o增加了变形延展模式。
o零售价格减少到1995美元。

Sanyo PLV-Z700规格

ANSI流明:1200

对比度(full on/off):10000:1

光路引擎:1920 x1080,原生16:9三片式有机LCD,配165W UHP灯泡。

视频兼容性:1080p/60/50/24,1080i,720p,576p,576i,480p,480i。

连接面板:两组HDMI 1.3b端口,一组15针脚VGA,两组3-RCA分量输入,一组s-video,一组复合输入,一组9针脚DSub串口。

镜头和投影距离:2倍手动变焦/对焦镜头,带有垂直和水平方向镜头移位。投影100英寸对角线图像需要10到20英尺(注:3.05米到6.10米AC)。

优势

对消费者友好的特性集合。Z700提供了一个平滑的电影般的画面,非常安静的风扇噪音,正常观看距离时无像素结构或纱窗效应。安装灵活性达到极致。藉由长达两倍的变焦镜头,三倍全幅画面高度的垂直镜头移位,以及两倍全幅画面宽度的水平镜头移位,你可以将其安装在你所希望的任何位置。Z700的低价格还包括了一个三年质保。总的来说,Z700代表了1080p投影的杰出价值。它使得预算有限的消费者无需大伤元气就可以更进一步获得理想的清晰度格式。

洁净的外观有一种质朴的优雅,使得添置一台Z700对于任何起居室或多功能家庭房来说都是受欢迎的。相对许多1080p家庭影院型号来说,它比较小巧,因此安装后不会显得咄咄逼人。其白色的色调使其相对于白色的天花板而言仿佛消失无踪。当不使用时,有一个会自动关闭的滑门,屏蔽镜头使其免于灰尘的聚集。这个滑门还会将镜头隐藏起来,使得这台机器不像一台投影机那样显眼。如果配合一张电动可回收屏幕,在不使用的时候,整个视频系统几乎能够从视野中消失。对于那些不希望自己的起居室被视频系统永久占据的人来说,这是一个巨大的有利因素。

ANSI对比度。我们的测试样机,ANSI对比度测得为277:1,相比我们去年测试过的各种基于LCD的家庭影院投影机,这个数据落在了典型的范围内。例如,三菱HC5500测得为260:1,而Panasonic AE2000则为305:1。因此就ANSI对比度而言,Z700和一些流行的型号相比是有竞争力的。

然而,Z700在对比度上相对Sanyo Z2000则是不进反退,后者我们测得为350:1。实际上,Z2000产生了去年所有LCD家庭影院投影机中最高的ANSI对比度读数。今年秋天就是另一回事了。新的高对比度LCD投影机,例如Panasonic AE3000和三菱HC7000能够产生超过400:1的ANSI对比度读数。当与Z700进行AB对比观看时,其对比度上的优越性尤为明显。它们比Z700贵出许多,但是你能够看到多付出的钱换来的好处。

然而,除非你用一台更高对比度的机器和Z700进行AB对比,否则你不会真的知道你失去了什么。当只有Z700这一台机器,在全黑房间中使用时,只要屏幕尺寸不是太大,就其画面而言不会有任何拖泥带水或者单调的抱怨。从最适宜的对比度和色彩饱和度出发,我们会建议将屏幕尺寸控制在100英寸左右。当然如果你想要更大也不是不可,但当你将图像尺寸推进到大于110英寸对角线时,就我们的喜好而言,你会开始牺牲过多的对比度。

亮度。去年的Z2000上有七种预设的校准模式,用于对应各种不同的全黑房间和环境光线观看类型--Brilliant Cinema,Creative Cinema,Pure Cinema,Natural,Living,Dynamic,以及Vivid。在Z700上这些选择被减少到了5个,即Vivid和Pure Cinema被去掉了。然而,视频优化模式的平均亮度增加了。此外,有七个用户可编程记忆位置,因此应可以进行任意的调整,将参数校准到你所喜欢的参数选择上。

Z700能够产生大范围的流明潜在输出,从较低的200到大约1200 ANSI流明。在其最明亮的设置下,Dynamic模式,灯泡为全功率,镜头在最广角端,我们的测试样机测得1198流明,正好达到其官方规格中的1200流明。对我们来说,最为令人满意的视频优化模式是Creative Cinema,该模式产生了411流明。如果你需要更多的亮度和更少的对比度,则Brilliant Cinema作为一个不错的备选视频模式,能够产生685流明。

就流明输出而言,你需要了解两个限制因素。首先,虽然长达两倍的变焦镜头给你了极好的安装自由度,但如果你将其安装在最大远摄设置时,你将会损失最高达37%的流明输出。在变焦范围的中间点,相比在最大广角时的最亮的位置,亮度输出缩减了16%。

其次,低功率灯泡模式也会将流明输出减少37%,这个减少量比起我们在大多数家庭影院投影机上见过的平均22%来说实在是有点多。底线是,如果你设置Z700为Creative Cinema模式,灯泡为低,变焦为最大远摄位置,你将仅仅得到163流明。这不足以点亮全黑房间中的任何大于80英寸对角线的屏幕。另一方面,确实也没必要这样干。大多数用家不会为低功率灯泡模式下的流明输出的损失而烦恼--即使在全功率灯泡模式下,风扇噪音仍然十分安静,此外,没有官方公布的低功率灯泡模式下灯泡寿命延长的说明。

有五种预设的色温选择。从最暖到最冷分别为Low 2,Low 1,Default,High 1和High 2。在我们的测试样机上,Low 1是针对电影的首选。然而,你可以对该选项或者任何其它预设选项进行任意的调整。和Z2000一样,Z700的色彩准确性是非常优秀的。运用相对均衡灰度跟踪工具来获得一个平均6500K色温的画面是有可能的。

以1080p解像度LCD面板,可见像素被减少到了几乎没有。离得很近地观察,可以看到明显的像素结构,而这些像素结构有利于图像的锐度。但是像素间的间距很小,即使很近距离地观看,纱窗效应也很微弱。一旦你退回到一倍屏幕宽度的观看距离,可见像素完全消失。

Z700具有一个较低温度的165瓦灯泡以及极低的风扇噪音。因此它可以被安装在一个小房间内。具有高瓦数灯泡的投影机在一个较小房间内会很快提高环境温度,幸而Z700只会散发出相对很少的热量。

连接面板在机器的后方。投影机深度为13英寸(注:33厘米),因此为线缆连接再加上额外约3英寸(注:7.6厘米),你可以将其安装在16英寸深(注:40.6厘米)的架子上。从后面看,排风扇在右侧,因此有足够的用于散热的空间是非常重要的,特别是机器的那一边。空气过滤器在连接面板的下方。正如照片所示,定期清洁时,打开格栅取出过滤器是很容易的。

对任何一台LCD投影机,时不时有灰尘颗粒落在LCD面板上是很有可能的,特别是如果你未能定期清理过滤器或者你处在一个灰尘特别多的环境里。LCD面板上的一粒灰尘会在投影图像上产生一个黯淡的、模糊的点。Z700自带一个手动气吹来去除这些灰尘颗粒,其喷嘴可以插入Z700外壳上的一个小孔。自己清理灰尘点可以给你省下将投影机送去清理的麻烦。鉴于我们从未在自己的Z700或者Z2000上有过任何灰尘点,我们还未能测试该功能的有效性。但Sanyo是唯一一个在其家庭影院投影机上提供此项功能的厂家。

新增的变形模式。Z2000不具有用于配合变形镜头的变形延展模式,而Z700提供了。

劣势

我们对于这个机器的抱怨几乎是零。遥控器的人机工程设计对我来说不如我所希望的那般的舒适,其菜单按键被设计在了一个有点尴尬的位置。另一方面,遥控器的控制范围很优秀,投影机也能够立即作出反应。被迫转身将遥控器指向投影机是件令人恼火的事情,而这种情况在其它一些竞争机型上是出现过的。

有两个控制选项会影响锐度。一种称为"Sharpness(锐度)",很容易在菜单的图像控制页面上找到。另一种是"Transient Improvement",被隐藏在菜单的Advanced(高级)选择内。Transient Improvement缺省为Low,从而干扰了你通过Sharpness选项对锐度进行精细调整的能力。为了获得符合我们口味的正确锐度级别,我们需要进入Advanced菜单关闭Transient Improvement选项。这是一个小的瑕疵,但却是用户在正常情况下有可能不易发现的东西。

很难说使用有机LCD面板是否应该被认为是个劣势。一般来讲,无机面板被认为在长期使用过程中更为稳定。但如果一台投影机被设计为具有足够的散热和紫外线过滤,在长期使用过程中LCD面板退化的可能性变得不再那么重要。好消息是Z700标配一个三年质保。并且投影机技术升级如此之快,以至于大多数使用前投的家庭影院发烧友最迟每三年就会升级到最新最好的型号。此外,Z700是这样的便宜,以至于你无需将其作为终身投资来考虑。实际上,大多数Z700的用家将会在Z700的质保到期的时候购买下一代投影机,因此对于他们来说,不论发生什么,有机面板都不意味着任何风险。

结论

Sanyo Z700是一台令人影响深刻的家庭影院投影机,它能够以非常低的价格呈现出理想的1080p解像度格式。其总的图像质量非常扎实,而其对比度相按照去年的1080p LCD标准具有竞争力。今年秋天,几台具有更高对比度的LCD型号发布了,其中包括最近宣布的Sanyo PLV-Z3000,该机搭载了65000:1的full on/off对比度(预定于十二月份上市)。Z700不会,也从未设想过与Z3000这一级别的机器竞争,因为更高对比度的型号售价至少要高出1000美元。基本上来讲,它给预算有限的消费者提供了一个特殊的价值述求--你可以用一个低到不能再低的价格获得1080p性能,并且如果你愿意放弃一些对比度你就能够多留1000美元在自己的口袋里。对于许多对价格敏感的消费者而言,这将是极为有趣的一笔交易。

鉴于在短时间内我们将推出其它1080p的评测,五星评级将推迟到我们能够观看和评估这个秋天上市的各个型号之后。然而,由于Z700突出的价格,扎实的性能和易用性,我们已经知道它将以其价值获得全五星评价。(完)

Hi Dominic, I just saw your posting today. The answer to your question, "Is 1080p really worth the extra $$?" is yes if your going to to be purchasing a blu-ray player in the future. If your main viewing is only going to be standard dvd's than a cheaper 720p projector would probably be better for you. I own the Sanyo 1080p, and no longer have much interest in watching or hearing standard dvd's anymore.

Blu-ray movies when encoded properly visually and sound wise, blow standard dvd's out of the water. Trust me, once you've seen and heard a high quality blu-ray movie you'll get hooked. I own 2 projectors at this time, and watch standard dvd's on my 480p projector. And of course my blu-ray movies on the 1080p. Safe to say my 480p is just collecting dust.

Besides watching movies I really enjoy the eye candy of blu-ray discs that show video of outdoor scenery like "Over America". This is where a big screen and projector come in handy.

I just bought the Z700 and now I am also trying to find the best fitting filmscreen. Either one with an engine (I am aware that the screen could get some waves with time) or a framed one. Is it really better to have a gray one over a white? I was looking at Steward and Projecta ones but couldn't decide what's best for this projector...

Hello, great comments guys. A couple of questions. I am considering purchasing the Z700 as my first foray into the front-projector world. This unit to be installed in a basement home theatre/family room. The setup of the room will be a variable viewing distance to about 18 feet max. The room has one egress window, of which drapes, and the screen will block out the diffuse light that enters. So basically the room will mostly be lit by artificial light and therefore 100% adjustable. We currently have a regular DVD and SD digital cable. In addition to the projector, I've also been told Santa is also bringing a Wii this year. So here are my questions:

Is 1080p really worth the extra $$? Should I be concerned with any real-world issues like SDE, color reproduction or any lag time for video games with this unit? Will the image quality on standard DVD or cable still be good or will an immediate upgrade to Blue-Ray and HD be required.

I appreciate any advice. Thanks, Dom

Mark W. I also got a z700 but when I start the projector autoiris is set to fixed. Other options are mode1 and mode 2.

I'm not good fine tuning my projector. Can you post your settings? brightness, contrast, and options you've enabled? thanx.

Jakob,

I have the 700 ceiling mounted and it is EXTREMELY quiet! I can hear my PS3 from across the room much louder than the 700 which is about 5 feet over my head.

Follow up:

Thank heaven, I figured out the Auto Iris thing. Set it to 'Fixed' in the advanced menu, then go to the 'Store' option to save that and any other preferences to a 'User' setting, then the unit will power up each time without defaulting to the annoying Auto Iris setting.

Whew! I was almost ready to send the unit back for refund.

I find it odd that the review didn't mention how awful the Auto Iris is. I don't consider myself a videophile (I AM an audiophile). I don't see how any self respecting videophile could tolerate an obvious pumping of brightness level. It's the same thing as over-compressed audio.

Just for your information:

German Sanyo website lists a lamp life of 3000h in Eco-Mode and 2000h in Standard-Mode. http://www.sanyo.de/products/lcd/projectors/homecinema/product_detail.asp?lg=D&PID=210&product=PLV-Z700&n1=1

There are few dealers that sell that unit for 999 Euro here.

I love this unit except for one big problem:

Is no one else bothered by the Auto Iris? In an attempt to keep contrast high, it pumps unnaturally. It closes in dark scenes, making them too dark, and opens in bright scenes. The 'pumping' from dark to light is very unnatural.

the feature can be disabled in the advanced menu, but the big problem is that every time you turn the projector off, it defaults back to Auto Iris.

I shoudn't have to go ddep into the menu every time I power up.

Does anyone have an answer to this?

Does anyone know if this unit suffers from any sort of ghosting at all? I'm looking to step up to a 1080p projector from a very old one, but I want to make sure it won't suffer tremendously whilst I play video games on it. I'm not really up to speed on the whole projector market, so is ghosting even a factor on any of these units anymore? Thanks!

Has it got the same problem as the Z5 when ceilingmounting it? That though you use it in eco/low mode the noise level is raised to the level when using it in normal mode.

In your article,you mention that "there is no published expectation of extended lamp life in low power mode".

I'm a little surprised by that! When reading on the subject all around the net, people always read that lamp life should be longer when using low power mode... How can you come up with such a comment and not back it up yourself?

Perhaps there are no published expectation, but is there something somewhere that prooves the contrary?

Thanks

Hello,

Have a question about your write up: "The difference between the Z700 and the Z200 are these" statement, you mention that the Z700 uses organic LCD panels.. BUT in your "SANYO PLV-Z700 Specifications you state "3 panel INorganic" Might want to check this out.

Thanks for your time,

Darryl Zimmer
