W4000與V4000當然是W比較好囉~
關於這個V4000值不值得購買...
小弟就比較不方便回答了...
小弟把FD77與V4000擺在一起...
只是因為價格相近又同為日系廠牌機種...

now more than ever this question is popping up.
The simple answer is as of now it makes little to no difference if you have a 10 bit or 8 bit lcd. The reason is because there is no 10 bit source out there to feed this 10 bit panel, and when u send 8 bit to a 10 bit tv the tv has to do more processing which everyone knows more thinking done by the tv means a lower quality picture.
With blu-ray now being the last form of mechanical source other then gaming there will be no source out there in the future either, the next generation of movies and such will be internet based and downloadable content, with compression rates of 13-1 and getting bigger online there is no need for 10 bit and satelite and cable company's have said they will not increase there bandwith wich means they cannot fit a 10 bit signal.
You may also notice the biggest player in lcd Samsung has gone with an 8 bit panel in all of
their new tvs and i can tell you i have seen a 8 bit samsung next to a 10 bit Sony XBR on a panel comparison using an HQV disc and there is no real difference Samsungs processing makes up the difference in colour recreation.So you don't get caught up in the numbers game just see if you like the picture.

大錯特錯! 還有你發的這篇是來自 AVSForum 的某人自稱 "I have worked in the electronics feild specifically with tv for the pst 5 years".
10bit is there to "reduce color banding". No matter what, 10bit panel is still better over a 8bit panel. 拜託不要自我安慰了。物理上你再怎樣8bit Panel 還是8bit Panel。 TN6bit再怎樣還是TN6bit不管你怎樣加2bit + dithering。顏色/色階方面還是大大輸True 8bit。
"You may also notice the biggest player in lcd Samsung has gone with an 8 bit panel in all of

最好是啦!!! 那個人本身資訊已經有限也錯誤。
"when u send 8 bit to a 10 bit tv the tv has to do more processing which everyone knows more thinking done by the tv means a lower quality picture." <- 你確定他真的"I have worked in the electronics feild specifically with tv for the pst 5 years"嗎? 他那五年做啥阿。那TN 6bit +2bit 其實也沒差啦。Electronic Field specially with TV -> 聽起來就是 Electronic Field TV Department 普通 Salesperson with lack of knowledge。更多顏色8bit 1677萬多色 vs 10bit 10億多色能使用，8bit 256 vs 10bit 1024更多色階竟然會降低畫質?!?!?! 毆買尬?!?!? 又不是拿1080i/P解析度放進1366x768Panel失去細節一樣東西。這位先生可能經驗不夠。
去看看A650/A750 side by side A550你就知道了! 哪有人把不同廠牌的bit Panel去做對比? 要看10bit vs 8bit要去把同牌的拿去對比。 拿不同牌的只會是自找麻煩。
有人會把10bit面板電視做得更爛嗎?
撥HQV(高畫質影片) SONY XBR 10bit Panel vs A550 8bit Panel，真的沒差嗎，他從頭到尾有注意到色階過嗎? 有注意到Overall的色澤飽和嗎? 我也可以說我在液晶電視界工作了十多年了~ 又是篇自我安慰的文章。
我覺得這位應該就是Sales
跟騙版大的那個人差不多。

"Television color
Most of today's TVs and computer screens form images by varying the intensity of just three primary colors: red, green, and blue. Bright yellow, for example, is composed of equal parts red and green, with no blue component. However, this is only an approximation, and is not as saturated as actual yellow light. For this reason, recent technologies such as Texas Instruments's BrilliantColor augment the typical red, green, and blue channels with up to three others: cyan, magenta and yellow.[3] Mitsubishi and Samsung, among others, use this technology in some TV sets. Assuming that 8 bits are used per color, such six-color images would have a color depth of 48 bits. "
10bit would result in "Color Depth" of 60bits with 6 Primary Color.
基本三原色不加額外的三原色 = Color Depth 30bit for 10bit Panel, Color Depth 24bit for 8bit Panel.
10bit Panel has the advantage of making the color bands smaller or even invisible in some cases.
10bit + 6 Primary Color = 專業美工美術人的最愛，精準的顏色以及範圍。
拍電影電視劇會用普通人用的攝影機去拍嗎? 你覺得堂堂大導演會用8bit攝影機去拍嗎? 廉價導演? 廉價設備? 裝笑尾~ (包含電影拍攝，藝術，遊戲製造，電視劇拍攝)
三原色
