Hy!
I have a Hyundai W240D with PVA (Wide Gammut) Display and a eye one 2. I had calibrated the two alredy when I bought the Ione2 and the problems where the same so I assume the filtes of the i12 have not aged.. My Os are Win10 and Ubuntu. Acutally I am on Ubuntu.
The problem I think is the wide gammut of the monitor and the lack of correcture in the i12 but as i have to admit do not really understand the conecpt of calibration etc, would you please help me step for step?
Summary: After calibration colors are reddish-neon, no way near perfect but not to badly off, but definitely off compared to the Facotry settings of the monitor.
Problem 1: On my i12 CD there are no correction files, I cant find any on the internet
Problem 2: First step of calibration is setting contrast, brightness and rgb settings. I read not to touch contrast as it leads to clipping. My monitor standard settings are:
brightness 90
contrast 90
Colours: Standard (other possible settings are reddish, blueish and custom).
On manual the RGB values of the monitor are 80,80, 80.
White looks perfectly white (evening, low led ambient light)
So I start calibration (monitor resetted to factory settings) and I get (see attachment “without calibration”).
Is that already the “offset” of my i12 because of wide gammut or is this a normal starting point?
Question 2: I know there are icc profiles for my monitor from hyundai, can I use them for something?
So when I try to try to raise the Red value i cant reacht the gray bar.
When I increase green to 76 rgb matches the grey bars.
my values are
r 80
g 76
b 80
(lowering green 1-2 points further results in huge jumps of the green bar)
Result: RGB is green in displaycal, but brithness if over the grey bar.
Monitor seems to have a light pinkish cast, white seems ok. Darg greys seem ok, light greys a littel pinkish.
Starting values of the monitors Brightness and Contrast
are 90 and 83. Lowering Brigthness to 85 bringts the contrast bar to the grey bar (see image2).
Is that a good starting point for calibration?
Should the picture already appear without colour cast?
Thanks
as I cant find an edit button, i reply:
I realize my first screenshot does not show brightness – i think that was because of the screenshot utility greying out the screen, but rgb is like it was.
So before I do calibration- dont I do something about the contrast? Dont I have to set the black point of the monitor? How do i know
my blackpoint is ok? Looking at:
http://www.lagom.nl/lcd-test/black.php
I can barely distinguish square 1 to 5 … Without any ambient light (night) I would say 5 is dark black.
Should I raise brigthness and instead lower contrast?
To my eyes the screen seems a little bright, how would I start with a lower candela value?
I now started gpick (colour picking util) and tested some areas that appear pink to me:
#f6f6f6 appears light pink to my eyes (roundcube webmail screen frame)
#f9f9fa seems pinkish too
#ffffff is ok
#7f7f7f is hard to tell, seems a bit into red but i am not sure
–> Does that mean I better not start calibration because I would loose too much colour space? On windows I did calibration from that pint on, I reached
ca78% colour room.
Or should I try to adjust RGB on the monitor to reach neutral greys? But what then?
added white
p.s.: i gave up calibration when I first tried when I bought the i12 because of that reddish tints and stuff and only now I stumbled upon displaycal
and read about the widegamut-offset and I thought that might have been the problem…
