不知各位大大對這2台畫質有何高見?
46Z5500算是sony高品質LCD..跟VIZIO 最新led比較.不知畫質誰較優.

Is 240Hz worth waiting for?
LG, Toshiba, and Vizio, on the other hand, use what's called "scanning backlight" technology. Instead of interpolating a second time, it uses MEMC once to get to 120Hz, in combination with a backlight that flashes on and off very quickly, to claim a 240Hz refresh rate. Notably, Toshiba used the careful phrase "240Hz effect" at its press conference to describe the scanning backlight method, although we doubt the distinction will filter down to the product packaging. I haven't reviewed any displays that use this method yet, so I can't speak to whether one method is better than the other.
LG、Toshiba和Vizio使用的是120Hz補插+背光插黑達成號稱240Hz
Vizio SV472XVT
The 240Hz processing uses the same "scanning backlight" variety as LG and Toshiba, which in our tests of the VF551XVT didn't perform quite as well as other varieties--but that's no big deal.
240Hz處理使用一樣的"掃描背光"方式如同LG和Toshiba
在我們測試VF551XVT中並沒有像其他機種那樣好，不過這沒甚麼大不了的

Vizio also claims a 240Hz refresh rate, which is designed to combat blurring in motion. There are two species of 240Hz and Vizio employs the "scanning backlight" variety, which augments the usual 120Hz technique of doubling the standard 60-frame signal with a backlight that flashes very rapidly on and off (much faster than humans can perceive) to help reduce motion blur. In our tests the other 240Hz technique, which actually quadruples the standard signal and is used by Sony and Samsung, produced better results than Vizio's method, which is also employed by Toshiba and LG. See performance for details.
Vizio VF551XVT評測第2頁
Video processing: First off we checked out the Vizio's motion resolution and were surprised that it didn't score as well as other 240Hz displays. On our test pattern we counted between 600-700 lines of resolution, just a bit more than we'd expect from a 120Hz model, as opposed to the 900-1000 lines we've seen on other 240Hz models with scanning backlights (namely, the LG and the Toshiba). Turning off dejudder dropped the Vizio down to between 300-400 lines, which is standard for any LCD. As usual, however, it was impossible for us to discern any blurring or other visible effect of this difference in program material, as opposed to test patterns. The Vizio also correctly deinterlaced both film- and video-based material.
首先我們檢查Vizio的動態解析度，然後我們意外的發現他的得分沒有像其他240Hz顯示器那般好
在我們的測試方式下計算出大概600~700線，只稍微超過120Hz機種
而不是我們看到的其他240Hz掃描背光機種在900~1000線（即LG和東芝）
關閉倍速功能後Vizio下降到300~400線，這是一般LCD的標準
不過，我們無法看出任何模糊或其他可見這種差別的影響，在節目素材，而不是測試模式。
