Hello, i have retired my 2 22" Diamond Pro 2070sbs and now have 2 Asus PA246Q Proart monitors.

I work with raw images with lightroom, capture one and photoshop all of which are set to work in ProPhoto rgb colour space.

These are my first wide gamut monitors so looking for some advice.

Out of the box they both have different look, one has slight green cast the other one a very slight red cast.

One also seems brighter, i have reset them both to defaults, but results are the same.

So how best to set them up?

I take i should set them to use adobe RGB mode in monitor settings?

I have an Eye One Display2 and intend to calibrate them with this, though should i try and address the colour cast first?

thanks
 
Hi, Think I would calibrate with the eye one first to see if it would produce the two the same you have nothing to loose as you can always step back.

I'm not surprised that you see slight differences between to similar monitors. This is why calibration is essential. Calibration should take care of the differences between the monitors

You have the Display 2 which should calibrate them both nicely. I'd opt for the largest number of colour targets that the software will let you use as you are opting for a wide gamut option. Asus claim these are 98% of the Adobe RGB gamut so that's the one I would opt for.
 
These monitors are supposed to be calibrated at factory and all reviews say that they are pretty good with this.

I tried with my eye one display2, but no matter what setting i choose the resulting profile gives a strong red cast?
 
Have you tried opting for sRGB rather than Adobe RGB as the colour space to see if that makes any difference.

I had a similar problem with a rMacBook Pro. The problem was down to a failed device. Replacing it solved the problem. Mind you it was over 5 years old and had been used a fair bit.

Is there anyway you can try an alternative calibration device to see if you have a problem. ?

Can you calibrate your old monitors ?

What settings are you asking the calibration software to aim for?
 
I don't think that 'factory calibration' answers the question, since a monitor is driven by a graphics card and that has to be part of the equation. Monitors can be set up by eye pretty well with many card drivers, and a previously known & tested image can be also used as a reference.

With your Asus's I'd at least start by setting the brightness to 50%. Or just follow the Eye One instructions?

Apart from that, some useful stuff here:

Hi and thanks for replies,

I did an ambient light measurement with eye one and got this:

With eye one i needed to reduce brightness to 40

I have tried with srgb and adobe rgb monitor profile both same results, also tried the ICC setting such as Version 2 or 4 and matrix or table with same results.

The eye one worked fine on my CRT monitors!

May try and see if borrow another calibration unit or buy later one.
 
If you've used your Eye-one to calibrate and profile your monitors then that should have got you to go through the steps to setup the brightness, contrast and colour temperature by adjusting the controls on the monitors.

Typically you should adjust the Brightness to 120mcd and the Contrast to 50%. Colour Temp should be set to 65k in my opinion and you do this by adjusting the RGB sliders on the monitor OSD. I don't understand your comment about reducing the brightness to 40. All these settings are displayed in the Eye-one software as you work through each stage and you see the settings as you make the adjustments.

The next step is that the Eye-one software will generate a profile for each monitor. This is what should be loaded into your graphics card and the Eye-one software comes with a loader to do this.

However, it's equally possible that you may have another loader on your system such as the Adobe Gamma software. If you have this then un-install it.

On the X-Rite disc there should be a utility called Displayprofile.exe. If you run this you'll see what profile is actually associated with which screen. Just drag the window onto each monitor to see what's set.

Once you've done all this your monitors should be accurately set and of course you need a colour managed program to make the most of them.


FWIW: A couple of months back my I profiled my dual monitors with the Eye-One Display 2 and got very strong red colour cast on both monitors. It transpired that my Eye-one had died. I bought the new i1 Display Pro and I'm back in business.

Thanks for reply.

I am working on OSX (hackintosh) and have been using eye-one display for my crt for years.

When doing a profile i have the option to measure ambient light so help with calibration, this i do with results posted in previous post, i do this rather that select Luminance preset such 120.


During calibration it ask me to adjust brightness to a specific level of which there is an indicator on screen to confirm correct adjustment. Once done it runs through the calibration with no further input from me. When finished i can create the new profile file.

This procedure automatically sets the new profile as default for monitor calibrated.

I can check this with Display option in system configuration.
 
What version od OSX are you running ?

I understand what you mean by reducing the brightness in the Displays option. 40 I think is too low opt for around 50. That's what I use on my iMac. You can also go through the calibration routine, skipping the steps until you reach the colour temp settings. Try setting this to around 6500K. Now save this as a setting with a special name ( so that you can recognise it. )Set this as the current default monitor profile. Now run the calibration software again. Leave the ambient setting off. Make sure you select White LED as the light source as I think this is what the displays use.

By making these adjustments you may get the monitor close to the result you want prior to calibrating thus giving the software a better chance. The recommendations work well for an iMac but I'm not 100% sure how well it will work on your hybrid system..

OK if that doesn't work, download a trial copy of Color Eyes Display Pro software. This is what I use, see if it gives better results. If you tell it that you are using an iMac it should set everything for you automatically once you've set the parameters you want. If that fails there is a manual option you can use.

Hope this helps
 
Thanks for reply.

The only software that works with eye-one display2 is i1profilerD2LionEdition which seems to work different to what you suggestion?

The first screen when profiling give me following options

Screen 1 or 2

LCD or CRT

White point, can be: CIE Illuminant D50 / D55 / D65 / D75 - Native - Daylight Temperature - XY... - Saved - Measure

Luminance: 80 - 100 - 120 - 250 - Native - Custom - Saved - Measure

I used colour temp of 6500k

I have not option for white LED

Once i have chosen this the second screen give options for:

ICC Profile Version - 2 or 4 (4 is default)
Tone Responce curve - 2.2 - 1.8 - 3 - SRGB (2.2 Default)
Profile Type - Table - Matrix (Matrix Default)

The only adjustment i make is after i start profile and this is for brightness, it give a bar and i need to set monitor so till it is at correct brightness.

This requires a setting of 40, you say this to low, but the default is 50 so it is not too far off.

Tried it at defaults and the same.

Will try the unit on my laptop to check if working ok

thanks
