I have just replaced my current monitor setup 3 x Asus 24" 1080p's with 3 AOC 25" 1440p's and I am unable to get the white to be the same on all three of the AOC monitors ...

I have not had this issue with my ASUS monitors I have reset the AOC monitors and also swapped over the cables and the ports that each monitor is using but this has not had any effect on the colour at all, my far right monitor is a nice crisp white the centre one is yellow ish and I think the left hand one is also ok.

so before I return this contact OCUK I just wanted to see if anyone else has had this issue.

Thanks deFiniLoGy for the Dell details ....

So after spending the weekend trying to get these three monitors to match I have failed ....

I have spoken to AOC Customer services and we went through the things I had been trying over the weekend so it doesn't look like I have missed anything so unless someone out there can help with this issue its looking like I'm going to have to return them which is a shame really as they are very sharp and clear and have a very nice finish to them ...

looks like my only other option is https://www.overclockers.co.uk/dell...reen-led-monitor-midnight-grey-mo-082-de.html
As I need VESA connection ...

Anyone have any more advice ???
 
Unfortunately there is quite a lot of inter-unit variation on most monitors these days, especially when it comes to native white point and overall colour balance (possible tints etc.). This isn't really AOC's fault and is usually down to the panel itself and specifically the backlight - the U2515H is subject to exactly the same variation.

One issue is that slight differences in how much phosphor is applied to the diodes in the backlight can have a dramatic impact on the native colour temperature. This can also change somewhat over time. This can sometimes be tackled by making appropriate adjustments to the colour channels, which is much easier with the aid of a colorimeter. You were fairly lucky with your ASUS models to have them match so nicely, but generally it doesn't work like that and you will find a colorimeter invaluable to help match things up. There are also some cases where the differences are too pronounced and regardless of the white point apparently matching (according to the colorimeter), there may still be some perceived differences. The more extreme version of this is when completely different models with different backlights are used - you can clearly perceive some differences even if you've matched the white point properly.

Here is the response from HQ

On the “ICC profile” section you can download ICC profile and there’s also a tutorial on how to install it. Once applied, all 3 monitors should look the same.

Hope PCM2 agrees?

Thanks for that ...

However after downloading the suggested file and spending almost 2 hours tring to tune my monitors without success :( i have given up.

Thanks for the help guys.
 
Yes, unfortunately ICC profiles need to be created for each individual unit. As above I would recommend your own colorimeter for colour matching of multiple monitors.
