Information about LCD monitor for design

“一般来说,LCD的色彩还原度很难有一个准确的数值去衡量,目前中高端的液晶面板所能够显示的最大色数都大同小异,但是由于其发光原理,LCD不可能达到像CRT显示器的那种正无穷色数”

“概括来说,就是要有尽可能小的几何失真率、足够高的对比度以及色彩还原度”

“一般来说,响应速度在25ms以下的时候,人的肉眼如果不是特别留意,是不会觉得画面出现延迟或者拖影现象的,这对与以静态创作为主的专业图形设计来说,是可以接受的。因此,笔者把适合用于专业图形设计的液晶显示器的最大响应时间指定为25ms,同时也建议大家在购买用于专业图形设计的液晶显示器的时候不必要求有过高的响应速度,一般小于或等于25ms就可以了”

“虽然250cd/㎡的亮度在很多中低端液晶显示器当中可以随意看到,但是,在实际使用中,这样的亮度已经足够了”

其實職業用LCD,
最主要睇個Panel,
Panel大約分為TN、VA同IPS,
TN Panel為現時LCD市場主流,
全因價錢相宜,
問題是TN Panel原生只有6bit 即26萬色,
需要依靠晶片抖色來達到16.2/16.7百萬色,
效果優劣全賴晶片及廠方技術,
TN Panel另一個遺憾是可視角度低,
同一畫面不同角度變色情況嚴重。
或會有意想不到的收獲~

 ViewSonic VP2250wb
“the use of wide color technology, which enables the VP2250wb to display 106% of the NTSC color gamut (most LCDs can display only 72% of the spectrum). In addition to providing brighter, more vibrant colors than a typical 72% panel, the VP2250wb gives professionals, such as graphic artists and photographers, a wider palette to work with and thus, a higher degree of color accuracy.”

 

“I fired up the DisplayMate (www.displaymate.com) suite of diagnostic software to test the VP2250wb and was impressed with the results. The panel did an outstanding job of displaying even the darkest shades of gray, though light grayscale performance was not quite as strong. Still, this didn’t seem to affect the color scales, which were uniform and well defined. Primary and secondary colors were incredibly bright, and there were no tinting or color tracking errors. Arial fonts set to 6 points were clear and legible, but smaller text (5.3 points) was not quite as crisp as I would have liked. If very small text readability is important, the HP w2007 may be a better choice, but it’s not a wide color LCD.”

“For the most part, the VP2250wb is a solid performer that delivers a brilliant picture with outstanding color quality. If you can live with its viewing angle and light grayscale issues, it’s a good deal for the money.”

VP系列:專為對品質最挑剔的專業用戶而設計的 VP 系列具有最佳的顯示器效能,
以及如 SuperClear MVA 超清晰畫面品質等技術,是專業繪圖、CAD 及桌上排版
人士的不二選擇。
但是22吋面板確是….TN  打去問工程師….得到的答案是26吋也有可能是TN…
(工程師根本搞不清楚….)
網頁上宣稱的MVA到底是面板還是啥鳥?三隻鳥中的哪一隻大鳥?

hmm照網頁提供的可視角度來看,只有21吋以下有可能是MVA面板… 22跟26確定都是TN面板
OptiColor 廣色域技術 – 超越傳統液晶顯示器 141% 超高顯色能力
優派全新的 VP2250wb 液晶顯示器,以符合高 106% NTSC 規範的新一代 OptiColor
廣色域技術,提供比一般 ( 符合 75% NTSC 標準 ) 的傳統型液晶顯示器,
高達 141% 的極緻顯色力;提供更寬廣、更鮮豔,層次更豐富的超高解像力,
讓您對顏色看的更多、更清楚!
這邊寫的超越傳統….141% 是以sRGB為基準去算的….不是以NTSC色域算….
寫的很弔詭~~~

106%NTSC /(75%NTSC=sRGB)===>141%sRGB顯色色域….
