Color gradation on VT30 is not perfectly smooth and we still haven’t seen a plasma TV without issues in this area (although Pioneer was close). In the darker end of the color gradient we did see some “bands”, which means that not all colors are perfectly distinguished. However, VT30 is definitely a good performer in this area but I have seen better results in terms of color gradation from some of the high-end LCD/LED models.
上面是说VT30的灰阶过渡不够自然,高端的LCD/LED在色阶过渡上要好于VT30
One of the reasons is that plasma panels use “dithering” to create new colors. Basically this means that some colors are being mixed (two colors alternating very fast in pixel areas) to reproduce new colors. Dithering is also visible on VT30 from a close distance. It’s not a big deal because from a typical seating distance it’s impossible to see but it’s part of the “color banding” issue so I thought I should mention it. However, I actually think that it is lower than on for example GT30 that we tested last month and slightly lower than on Samsung’s plasma TV (or to be more precise, it looks like a different dithering algorithm).
这个是编辑在近距离可以看到vt30的抖动,但是正常距离是看不到的,这也是导致color banding问题......
这个比较无语,抖动做到人眼可以察觉.....
However, I noticed some noise around fast moving objects. It’s not caused by the IFC (Intelligent Frame Creation) system because it’s there even if IFC is off. I don’t know exactly why it happens but I have not seen it on previous Panasonic high-end models. It’s not critical but you might notice it from a close distance.
前面漏了一些我不贴了,意思是说vt30的黄绿拖尾现象甚至比先锋还要不容易可见,但,快速移动物体周围却出现了噪点(非IFC导致,编辑说已关闭IFC),之前的旗舰产品,应该说的是vt20,却没有这个现象.
Black depth on Panasonic VT30 has been improved from last year’s VT20/VT25 - and there’s a visible difference in a side-by-side comparison. VT30 also beats Samsung’s 2010 C8000 / C7000 plasma-TV. However, the best black levels today are still achieved on LED models with local dimming, such as LG LE8500 or Bang & Olufsen BeoVision 7-55.
Shadow detailing on VT30 is impressive and it reproduces almost every detail in the darker areas. I did see some dithering in the dark grey tones but only from a close distance and it is impossible to see form a typical viewing distance.
black level不理想,不敌带LD的液晶,另外,后面那个是说灰阶抖动还是说黑位抖动(即黑色不稳定),这个有待商榷.
But we also have to put things into perspective here. When it comes to picture quality Panasonic VT30 is not a huge revolution, and rather an evolution. This has been the case with Panasonic’s high-end models for a few years now and I have to say that if you already own the VT20/VT25 from 2010 there is not much incentive to upgrade. Sure, things have improved but not drastically. Also, a few years back the gap between plasma and LCD/LED was very wide but in the recent years I believe that this gap has narrowed.
总结:vt30较vt20只是进化而非革命性变革,过去LCD/LED与等离子差距很大,但近几年已经很接近了 |
