[操作疑難] Spyder 4 + dispcalGUI 疑難

本帖最後由 pippen_33 於 2015-9-7 23:19 編輯

小弟是cal mon新手, 遇疑難想向各位師兄求助,  謝謝

Monitor: Dell U2414H
Display Card: NVIDIA GeForce GT620M (HDMI output, 已將output range set做"0-255")
Calibration: Spyder 4 + dispcalGUI

正常用個mon一個鐘以上熱機, 正式開始cal前熄晒燈拉晒簾仲要係夜晚
先將個mon既setting改番做default (brightness=75, contrast=75, custom color R/G/B=100), dispcalGUI setting如下:

Interactive display adjustment兩組bar都變左綠色字有剔剔 (brightness=41, R=100, G=92, B=95):

跟住唔理佢去瞓, 第二朝起身見佢cal完:

小弟既問題係, Dell官網話隻U2414H cover到96% sRGB, 但小弟cal左幾次都係約86%-88%, 想請問小弟係咪有邊個step做錯左或dispcalGUI set錯左, 謝謝

我都係 u2414h  我有sypder 3 /5
但未得閒試 , 請問有咩留意?

120cd/m 會唔會太光? 平時我隻mon 我set 25-30 brightness架ja
等我搵日得閒 試下cal 比較下result..  死la 原來我地隻mon 可能90% srgb 都出唔到.. 聽見好灰..
希望師兄只係setting 問題

The Interactive Display Adjustment is one tricky part, similar to that inside Spyder software
You'll need to take a lot of time just to get the bars right
But once done, you're good to go

Actual calibration results also depends on environment, eg. how proper your room is lit
It's suggested that you turn off all lights prior to actual calibration

And yes it is important to understand every parameter setting under the Calibration dialogue
Set one thing wrong and your calibration may not continue or complete

Do however know that dispcalGUI/ArgyllCMS is freeware and constantly under development, so bugs are quite likely (even though you have all the settings right)

As for sRGB coverage, are your sure you've set your monitor to the right mode (eg. "sRGB")?
If not, do that again

Thanks for your help and advice

夜晚熄左燈拉左簾, 基本上都已經差唔多全黑

dispcalGUI setting大致跟以下呢個教學, 除左White level=120 cd/m^2, Black level=As Measured, Profile type="XYZ LUT + matrix", 亦試過White level=100 cd/m^2同Profile type="L*a*b* LUT"但結果Gamut coverage都係一樣

Monitor setting選custom color, 因為只得custom color可以係Interactive display adjustment時獨立調R/G/B

希望師兄可以幫忙再作指導, 謝謝

120 cd/m^2都ok唔算太光, 另外小弟見網上cal mon教學都係100或120多

小弟大致跟以下呢個教學做, 佢隻Dell U2412M有 98.7% sRGB coverage (唔知U2414H係咪差唔多型號)

師兄快D試下啦, 之後可以教下小弟

我嘗試以自己有限經驗同師兄分享下,希望幫到你
事前功夫:
1. 準備好調色器 + dispcalgui + 第三方Argyll Driver
2. 開Mon預熱1小時
3. 閂晒所有燈/簾,儘可能接近全黑的房間
4. 桌布先改回全黑純色
5. 關閉多餘程式
6. Mon恢復出廠設定
7. 用Custom Mode

DispcalGUI 3.0.3.0
E個Verison喺Profile setting內Testchart file唔夠2.6.0.0完整,
如Cal Mon需要2527個Testchart file.

我的Setting:

跟住就開始Cal
我用i1Display Pro好快Cal完(印像中少於1小時)

然後install就搞掂.

大約一個月左右要Cal一次,
但簡單同快好多,
去Calibration>Update calibration>Calibrate only就搞掂



網上有人話win7個色彩管理會三不五時將顯示卡LUT歸0,
桌面右鍵>螢幕解析度>進階設定>色彩管理>裝置>設定檔>合併我的設定與系統設定
進階>變更系統預設值>進階>使用Windows顯示器校正


如果想睇下其他Report之類,
可以去Tools>Show curves

又可以點Settings最右邊個圖示Profile Information

2015-9-8 23:56


仲有一份Delta E Report
點Vertification>Testchart of reference>verify_extended.ti1>Measurement report

跟住再過Tools>Update Measurement report

仲有樣幾複雜ge MADVR,有需要我比link師兄慢慢搞.

我隻平價Philips IPS 用Spyder 4+dispcalGUI cal完都有97.6% sRGB,無理由Dell會少過佢。

Contrast唔好改用翻原廠設定,通常係50%,如果唔係會有影響。

dispcalGUI作者在官方網站寫明Contrast唔好搞!

Adjusting a LCD display

For LCD displays, you will in most cases only want to adjust white point (if the screen has RGB gain or other whitepoint controls) and white level (with the white level also affecting the black level unless you have a local dimming LED model), as many LCDs lack the necessary "offset" controls to adjust the black point (and even if they happen to have them, they often change the overall color temperature, not only the black point). Also note that for most LCD screens, you should leave the "contrast" control at (factory) default.

我用WIN10 ,暫時用唔到dispcalGUI,官方竟然因DRIVER問題無法使用。仲唔知幾時會更新?
