looks great for the price overall, but the colors are off. I don't mind getting a spider or something to calibrate it, but I think I read somewhere that connecting through a display port might be an issue with calibrating it correctly?

My work system is a loptop with only a display port (an ati based system, no nvidia) so I'm kind of stuck using that.

is there a known issue with this type of connection or will a calibrator do the job just the same? I'm on win 7

got this for u Tsa

That monitor is 10b/pixel, which means it'll run in wide color gamut by default.

Try to find in the controls if you can specify what color more it's operating on, and pick RGB/sRGB if the option is available.

bit depth and color gamut are completely independent. Generally speaking, a higher color gamut will benefit from a higher bit depth (as you need more steps to reach those saturated primaries from white), but just because you have a 10 bit display doesn't mean it's going to have a wider gamut.

Where did you find out that the monitor is 10 bit?

Sorry for late reply but it has no sRGB mode at all

Julios, thx for your replies BTW, blues look more like cyan. As for skin colors, I guess if I have to generalize I would say they are more towards the red hue than they should be. But the cyan ish blues are very obviously wrong

Does this image look cyan on your display?

k sorry for the late reply again, I'm making the flow of information frustrating :/

what u posted actually looks true blue, but something like this:

looks a lot more green that it should.. i would identify that color as green on my 30", but as blue on my smartphone , and secondary screen.

play with the rgb settings

or send me the monitor and i'll test it

i have the i1 pro2 handy

well that's a good sign that a blue signal (which is what I posted) actually looks blue. It probably means your primaries aren't that off, but the way they're being mixed together is off (i.e. white balance). However, without proper testing, this is hard to tell. I'm assuming a pure green signal and a pure red signal look green and red?

If you have $250 to spare, I really recommend the i1d3. It's a very impressive piece of hardware that you can do a lot with.

http://store.spectracal.com/oem-i1display.html

If you decide to go this route, lemme know. I know the guys that run spectracal and can ask them whether they have calibration tables built for your display.

If you don't want to spend money, you can hire a calibrator, or rent a colorimeter, or do it by eye. Doing it by eye is not going to work very well, but it may at least reduce the problem. One idea is to load up a grayscale ramp such as this one:

[lvlshot]http://i.pbase.com/o4/78/287278/1/91136 ... ps0255.jpg[/lvlshot]

and adjust the RGB sliders until they actually look achromatic. Be careful though - you can go down all sorts of rabbit holes doing this by eye, and depending on how the adjustments are actually working, you may mess up the gamma also (and gamma is very important for perceptually uniform rendering of tone variation).

Perhaps start by nudging the green slider down a bit.

It is probably best if you do this in a dark environment, so you aren't adapting to light that has the wrong chromaticity. Also, the presence of colored objects in your environment can greatly influence your perception of color, so if the display is lighting up nearby objects, especially those surrounding the display (e.g. bezel, wall behind display) try to remove the ones u can.

I'll keep that one in mind, and the idea of renting something sounds appropriate, since it's something I will not be needing on a regular basis. Thank you sir, you make informative replies :up:

nice piece of hardware. I have the i1 pro rev D, which is very similar. With HCFR (free software), you can actually get the raw spectroradiometric measurements, which is kinda cool :)

I got a new 24" Dell IPS monitor a few weeks ago that had off coloring and bad gamma. I found the ATI color calibration to be crap and it got a lot better disabling it and using window color calibration. I made sure the monitor control panel had colors set to neutral so the only factor in play was what i set in windows color calibration. Easier to get something right if there's only once place where crap could be happening.

yeah, like my uncle having to setup color profiles for many things did get confusing, this on Win7pro, i was drunk told him to fuck off

It's OK, dE can be up to 1. I've noticed it on a few of them, but I'm mostly using them for press proofs. All the screens I work with are self calibrating, just use the i1 to make iccs.

This is real shit

Another forum I post on (it's a UK one so shipping is far easier) had a great system where members who wanted to calibrate their monitor could borrow a calibrator from another forum member. When they'd done it they'd just ship it to the next member who wanted the calibrator at their expense. Worked well :up:.

Nice. From what I understand, working in the print industry is a whole other ballgame, coz you have to maintain color management between displays, scanners, printers. Plus you have to understand additive as well as subtractive color mixing, and spectral reflectance. I think I'm gonna stick with displays for now :)


btw if I had the money I'd go for one of these - I think the photo research unit is probably over $40k.
