但X系列總歸是頂級系列，沒道理會輸給次次級的D系列，就算今年的W系列了不起跟去年的X打個平手罷了吧？尤其是那些低規格的訊源，X系列才有比較好的處理能力，應該在這方面明顯勝出才對。我這台06年的背投機種（基本上和你的X2000有相同的處理器核心和韌體功能），在這方面的表現就真的不錯，根本不需要什麼昇頻播放機，直接吃480i的DVD訊號就很棒了（我是買了一台還算高檔的1080p播放機比較之後才真正了解這點的）。看480i的數位電視也是嚇嚇叫，完全巴死剛出的那台華碩42吋液晶（60吋的畫面比42吋的還清晰，顏色對比等就更不用提了，一個是傳世巨作，另一個是油漆師傅畫的電影看板）。
不過畫質這東西，（我自己覺得）很難拿來找廠商理論。我自己也是為了這個畫質問題快被那台華碩液晶搞瘋了，甚至我弟弟去年買的大同便宜貨都比它強（至少是看數位電視的時候），但是我鍥而不捨每天給它調給它測了快三個禮拜，終於讓我用測試片發現明顯的低亮度時螢幕亮度不均的問題，就靠這個我才好意思打華碩的客服專線請他們派人來看。不過，就算我已經把問題描述得很明確清楚，他們還要我寄照片給他們參考，到現在還沒敲定時間。
據我所知，X2000的時代，Sony的液晶有很多機型都有洩光和光斑的問題（全暗時可以看到雲狀的光暈散佈各處），這會影響陰暗場景的畫質，在美國風波還鬧得蠻大的。
for example, when Intel come up with new CPU, the new CPU, although lower price, has better performance than previous generation higher price CPU. I think it is well known and accepted.
This is what i see and confirmed by the retail store manager.
1. the 46W3000 DO has better picture quality than 46XBR4. because it use newer panel and newer scaler.
2. when you ware watching Blue-Ray movie, the scaler will do very little or nothing. because the movie is play at 1080P, and the panel will just accept it natively and display. (works like computer screan) in that case, panel quality is more important. 46W wins XBR4.
3. when input analog signal, for example, VCR or lower quality meterial. XBR4 wins by little. because scaler become the deciding factor here.
this is what i know,
1. Human eyes are more sensitive to color than pure resolution. as a result, a display with better color will appear "better" to our eyes comparing to a higher resolution display with less color.
many retailer in the US are prised 46XBR4 the same as 46W3000. some of them even put them side by side and connect both to the same Blue-Ray player. it's obervious that 46W has better quality, especially the dark area. however, XBR4 has "better" exterior desian called "floting glass". The manager said, if you like the design, pick XBR4, if you like picture quality, pick W series. both are the same price.
another thing i noticed about XBR4 is fast scene. while i was watching spiderman 3, and when Parker was flying, the display has "cube" effect similier to "mosic effect". the store manager didn't know why cause "in theory" that shouldn't happen.
about the 120Hz. the advantage is that from 24P vidoe, it can do even upsampling. (just times 5 on every frame) so the video will looks smoother. however, i kinda believe that screan is still output in 60 Hz. so the smoother looking vidoe are more like better scaler and got nothing to do with panel quality.
First, XBR4 has same panel as W3000. Sony won't put a inferior panel in a higer class TV, it doesn't make any sense. And what's meant by newer scaler? Doesn't XBR4 has newer scaler than XBR2?
Second, XBR4 has the 120Hz support that's really important to 1080p/24.
Third, XBR4 has full scale processing for signal from 480i up to 1080i, using more powerful engin.
CNet also said, XBR4 is the best LCD TV ever made; not comparable with Kuro plasma or SXRD rptv, but definitly the best in its catagory, period.
if you are on the market for a new LCD, maybe u should ask the store to hook up both and compare side by side. i was so ready go get a W but the recent price drop on XBR4 make it very difficult decision. it's really strange, i must say. (both LCD are set at decault setting, though)
and for Kuro, it's in a class in itself... no comparison wins hand down compare to any LCD right now. just the price is hard to swallow for me.
By the way, you shouldn't be complaining the Kuro price. Pinoneer Taiwan taxes us NT$240000 for the 50" FD. Looks like it's determined that rational Taiwanees are not deserved that level of PQ.
