新手上路，也来聊聊LG的60LA8800

mmmmmmmmmmmmm

为什么选择这个型号，因为看到这个坛子里某位大神每次推荐型号中80%都会出现它，处于好奇，就去研究了一下，当然，研究的主要动力还是自己要买电视

先来看一段来自CNET的评测吧，由于LA8800只在大陆出售，其余地区为LA8600，故以此作为参考，考虑到电视机主要还是以看电视，看电影为主，什么动感遥控器，什么3d，什么外观的，这里就不讨论了，我截取了一段关于图像的评测，作了一下翻译，原文如下：（由于不是很专业，有的地方翻译得不是很准确，望指出，勿喷）
Picture quality（图像质量）
Although it delivers somewhat better picture quality overall than last year's LG sets, the flagship LA8600 doesn't really come close to matching the best-of-breed 2013 examples from Sony and Samsung, and also falls short of Vizio's much less expensive M series. Its main weakness compared with those sets is lighter black levels, and it also couldn't match the uniformity or bright-room performance of their screens. On the plus side of the ledger the LA8600 showed accurate color and very good video processing, as well as the expected benefits (and issues) of passive 3D.
尽管画质比去年LG所有型号有所提高，旗舰机型LA8600还是没能达到2013年Sony和Samsung的高度，甚至达不到Vizio的M系列水准；其最大的弱点在于黑位的控制和亮度均匀性控制上。但也不是一无是处，起码在色准，图像处理能力和不闪式3d功能上还是值得肯定的

下面他们做了一个横向的测试

对比型号 (details).
Samsung UN55F8000 55-inch LED LCD.
Sony KDL-55W900A 55-inch LED LCD.
Panasonic TC-L55WT60 55-inch LED LCD.
Vizio M551d-A2R 55-inch LED LCD.
LG 47LM7600  47-inch LED LCD.
Panasonic TC-P60VT60 60-inch plasma.


Black level: Aside from last year's LG LM7600, the LA8600 delivered the lightest, least realistic shade of black in our lineup. The Samsung, the Sony, and the Panasonic VT60 were all significantly better in this important performance category, and the WT60 and Vizio both also managed to get consistently darker as well.
黑位：除了去年的LM7600，LA8600在黑位控制上可谓是一塌糊涂，而Samsung，Sony和Panasonic的VT60都表现得比他要好很多，WT60以及Vizio同样一如既往的表现出色

As Bond creeps through the building at night for example ("Skyfall," Chapter 11), the 8600's rendition of the silhouettes, the deepest shadows and, most tellingly, the letterbox bars, lacked the inky depth of the better sets. The darker the overall scene, the more the LG struggled to keep up with the others, but even when bright elements like the neon at 47:15 were introduced, the LG's bars still appeared a good deal lighter than any of the others except for the LM7600.
在007天幕坠落的第11章一个场景，邦德在黑夜中爬过一个建筑物的时候，8600对人物轮廓以及暗部阴影，尤其是看电影上下的两条黑色，缺少暗部的深度，画面越暗，LG越不及其他几个型号，但即使在47分15秒的霓虹灯下，LG所表现出来的上下边还是比其他几个型号要弱，LM7600除外

Blooming is an artifact of local dimming where a relatively bright section of screen artificially brightens up an adjacent dark section. While the LA8600 didn't show as much blooming as the WT60 it was still a worse bloomer than the others. In Chapter 14, as Bond's boat passes the night-lit dragon under the fireworks, I noticed a relatively bright patch illuminate the top bar as the dimming system kicked in. At least the LG didn't dim highlights as much as the WT60 and, to a lesser extent, the Vizio M series.
“模糊现象”是调光的副产物，当比较亮的区域要转为较暗区域的画面时，会减轻邻近区域的灰阶层次。尽管LA8600没有像WT60那样出现那么多的“模糊现象”，他还是比其他几个型号要严重，在地14章，邦德划船经过烟火下的night-lit dragon时候（没看过，不知道是个什么龙），在调光系统介入的时候，我发现在顶部有很多光斑。但至少LG不像WT60那样

Shadow detail was a relative strength, on the other hand, although not up to the Samsung, Sony or the VT60 plasma. The face and jacket of the doomed sniper (49:45), as well as Bond's shadowy stroll the dim Macau bar (56:29) were both rendered in with plenty of detail, neither too dark nor too bright. Shadows didn't look as realistic overall as on the sets with deeper black levels, however.
暗部细节相对强一些，换个角度说，尽管不如三星索尼或者松下的VT60，在49分45秒狙击手的脸和衣服以及52分29秒邦德在澳门吧闲逛下的暗部都很好的表现除了细节，不会太暗或太亮。不管怎样，在深黑的状态下，阴影细节还是真题感觉不真实

Color accuracy: LG has few problems in this area, exhibiting more accurate color than any of the others aside from the Sony, the Samsung, and the VT60. Skin tones, from Bond's craggy visage to the darker face of Eve in the brightly lit market chase from Chapter 1, has a natural color that was neither too warm nor too cool, and color stayed consistent regardless of the brightness of the scene. In darker scenes the 8600 avoided the reddish tinge found on the Vizio, for example in Bond and Severine's face from the Macau bar in Chapter 14.
色准：LG在这个方面没有任何问题，表现出了很高的准确性(还是不如索尼，三星和VT60)，肤色，从邦德的面部轮廓到第1章在市场追逐时候脸部较暗的地方，都表现得比较自然，不会太暖，也不会太冷，哪怕在比较亮的场景，颜色还是保持了一直。在黑暗的场景，8600也没有像Vizio那样略微泛红，比如14章在澳门的那个那个场景邦德和塞弗林的脸。

Compared to the sets with deeper black levels, colors on the 8600 didn't show quite the same punch or saturation overall. The exception was the WT60, which did appear a bit more washed-out in brighter scenes, for example the faces of the Bond and his contact at the museum (Chapter 10).
在更深的黑位下与其他型号比较，8600的颜色没有表现得不太一样。WT60倒是例外，在较亮的场景下，出现了饱和度不足现象，比如在第10章博物馆邦德和联络人的脸。

The LG's only major downside in this category was a direct result of lighter black levels: black and near-black areas, like the letterbox bars, showed a bluish tinge. The other non-LG LEDs, as well as the plasma, showed a truer shade of black.
LG最主要的劣势是在轻黑位下的问题：黑色和近黑色区域，就像宽屏上下那两条黑条，有点点发蓝，其他的非LG液晶电视，包括等离子，都能真实的表现出黑色

Video processing: While not quite the equal of the Samsung in this category, the 8600 nonetheless performed nicely. Of paramount importance was its ability to deliver true 1080p/24 film cadence without sacrificing all of the motion resolution benefits of a high refresh rate. It achieved this result in the User setting under TruMotion, with De-judder set at 0 and De-blur at 10. It also showed correct cadence in the Off position, but that setting showed a marked decrease in motion resolution.
影像处理：虽然不完全和三星一样，8600仍然表现出众，最重要的是在放1080p/24电影的时候没有牺牲动态分辨率，这要归功于他的高刷新率。用户通过在TruMotion下设定防抖值为0，设定防模糊值为10来实现。如果把它关掉，也不会有太大的影响，但是会减小动态分辨率

Aside from Off and User, all of the TruMotion settings delivered around 600 lines of motion resolution, consistent with a typical 120Hz TV. The exception was Clear Plus, a mode that introduces backlight scanning to hit the 1,200-line maximum I expect from the 240Hz TVs of today. The Smooth, Clear Plus, and Clear settings introduce the smoothing Soap Opera Effect to a greater or lesser extent.
除了关闭和用户设定，所有的TruMotion设定都能满足600线的动态分辨率，与传统的120HZ电视一致，例外的是Clear Plus功能，这个功能增加了背光扫描和我所期望的240HZ电视一样可以最大实现1200线的最大值。流畅度，Clear Plus，清晰度设定，多多少少增加了看肥皂剧的乐趣

Unlike previous years, LG's User dejudder setting is nicely incremental -- higher settings introduce progressively more smoothing in a linear fairly gradual way, so you can tune it how you like it. I still preferred the 0 setting, while 1 and 2 seemed to introduce 2:3 pull-down's halting cadence, but 3 was a nice compromise and might even be preferable to 0 for some smoothing-averse viewers.
和以往几年不一样，LG的防抖设定明显有所提高-这种模式的介入通过线性的，逐级的方式可以逐步提高平滑度，因此你可以根据自己的喜好进行设定。我个人还是比较喜欢设置为0，1和2好像会产生 2:3 pull-down's halting cadence（太专业了），但是设定为3好像也不错

Input lag in Game mode measured a respectable 51ms. I've heard that some LG TVs can achieve better lag scores if you rename one of their inputs "PC," but in the 8600's case that didn't help; I measured 65.7 in that setting.
在游戏模式下的输入滞后性测出来达到了51ms，我曾经听说LG的电视可以在当你重命名你的输入设备为PC时表现得好一些，但是在8600上貌似不行，在那种情况下我实测出来达到65.7

Uniformity: Although not terrible, the screen on my LA8600 review sample did show more uniformity issues than the other LED LCDs in our lineup (aside from the other LG). Along the top edge, right in the middle, a relatively brighter area was visible in the letterbox bars, and as noted above its brightness fluctuated noticeably with program material. In some very dark scenes the upper-right and lower-left corner areas appeared lighter too.
均匀度: 虽然不是很糟糕，比起其他几个型号来说LA8600还是反映出了很多均匀度的问题。沿着电视机顶边，右边靠中间的地方，一块相当明显的光斑在看电影的那个黑边上，随着场景的变化，光斑还会随之波动，在某些很深的场景，右上部份和左下部分也会出现这些光斑

That said none of these bright areas were severely distracting to my eye, although as always different review samples might show more or fewer hot spots. As usual the issues became much more visible when I switched off local dimming, although they weren't as bad as what I saw when I turned off the Samsung's dimming.
这些光斑会分散我的注意力，虽然不同的测试样品多多少少都会有一些问题，通常当我把本地调光关掉的时候，这些问题变得更加明显，然而当我把三星的调光功能关掉的时候，好像没有那么糟

The LG maintained color fidelity from off-angle better than the Sony and Samsung, which got washed out and paler more quickly, but on the other hand it also lost black-level fidelity quicker--so overall, off-angle was basically a wash (so to speak) between the high-end LED sets. As expected the Vizio and Panasonic performed about the same as the LA8600 when seen from off-angle, and the plasma was the best in the lineup.
LG的可视角度比索尼和三星的药好，当角度发生变化时后两者会有明显的变色，可视角度在旗舰电视的评测中还是不必可少的，如我们所料一样，Vizio和松下的表现和8600一样好，等离子无疑在这方面表现最为突出

Bright lighting: Under the lights the LA8600's mostly glossy screen does little to curb reflections, which appeared a bit dimmer (better) than on the Samsung and Sony, and quite a bit dimmer than on the WT60, but not as nicely muted as on the other LG or the VT60 plasma, let alone a true matte LED LCD (as for the Vizio, it appears to have the same screen finish as the LA8600). On the other hand the Samsung and Sony preserved black level fidelity a bit better than the LGs, the Vizio and the plasma under the lights, and as a result I liked their bright-room picture better overall by a nose.
亮度：当外部亮度较大的时候8600会有些反光，因此会感觉比三星和索尼要暗，比WT60就更加暗了，但是比其他的LG或者VT60也好不到哪里去，更别说真正的LED了。另一方面，三星和索尼在在光线下的黑位表现上确实比LG，Vizio和等离子要好，这使得我更喜欢他们播放明亮的室内图片。

In the "torch" mode picture setting that delivers the most light output, which in LG's case is the Vivid setting, I measured 92 fL (footlamberts). That's not quite as bright as the Samsung (127), the WT60 (123) or the Sony (107), although it is significantly brighter than the VT60 (49) if not the plasma light output champion, Samsung's F8500 (83). The LEDs also maintain that light output with full-screen white (think hockey or a browser screen), while the plasmas attenuate. To put the numbers in some perspective, however, the VT60's maximum of 49 is bright enough for the vast majority of normal living rooms. But as usual, if you can't control ambient light and have a very bright room, or just prefer a witheringly bright TV image, an LED like the LA8600 is a better bet than most plasmas.
在torch模式下图片最亮，在动态场景下，我测到LG的亮度为92fl。比三星的127，WT60的123，sony的107要小，比VT60的49大，还有就是三星的等离子最亮电视F8500，达到了83。LED电视在全白屏幕（比如曲棍球和浏览器）状态下同样保持了很高的亮度，而等离子却略微弱一些，为了表达自己的观点，用了一些数字，但是不管怎样，VT60的最大亮度49已经足够满足客厅的需要了。但是通常来说，如果你不能控制环境温度的话或者是你家的屋子光线很足的话，或者是喜欢很亮的电视的话，LF8600比起等离子来说还是比较好的选择

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

看来，在资金充足的情况下，几个液晶的旗舰机器中，首选还是samsung的F8000，其次是sony的W900A

感谢楼主翻译，测试表明LG电视属于平庸的产品，同档次产品还是不如索尼，三星，松下画质控制好

[s:97] LG漏光是挺严重的

但是应该看到LG便宜很多很多 特别是网络上

mmmmmmmmmmmmm

其实lg和其他几个机型比起来也就价格优势了，但话说回来，国产机器便宜得多，今天去苏宁问了一下长虹新出的4k曲面oled，55寸1w3，比8800性价比高太多了

tim1018

感觉还是自己去卖场看看，多比较吧……cnet也不是很靠谱……8800在旗舰型号里性价比不错，不是说画质很棒。
