Hi all

I will soon be looking for a new monitor as both my current ones (Samsung T240 & ACER AL2202W only just display the sRGB Gamut and i need one that can display the Adobe1998 Gamut

But how can you find this out as most of the monitors I have looked at online do not list that as an option

Even the Dell ultrasharp U2414M often recommended does not list it in the specs so how di I tell if the monitor I am looking for is sutable for the Adobe 1998 Colour Gamet.

I assume in the example below its something to do with the 16.78 million colours, if correct what are the colours for sRGB, Adobe1998 & ProPhotoRGB Gamets

It also says below Colour Gamet 82% (CIE 1976) what does that mean.

Thanks for any help with this

Paul

If you want to display Adobe Rgb then your going to need a wide gamut screen like the Dell u2713h (not the hm) as for prophoto I'm pretty sure there aren't any displays capable of displaying it, even the Dell I mentioned only does 99% aRGB
 
Look at respected review sites.

TFT Central always give very detailed information regarding gamut.

I've got a great deal of data I've personally gathered too, using pretty much the same testing methodology.

The Dell U2412M is sRGB gamut essentially. A little bit more actually when I tested it.. but not by much.


Gamut is nothing to do with the amount of colours. Pay little attention to that anyway... that whole 16million colours thing is based on 8bit colour as a theoretical number... it's not actually measured in anyway. An 8bit screen with a sRGB gamut can display the same amount of colours as a 8bit screen with a Adobe RGB gamut, as all that figures assumes is the amount of discreet steps between colours for 24bit (8 bit per pixel) colour. Essentially... 256 levels of red, 256 levels of green and 256 levels of blue....

256 to the power of 3 = 16777216

Simple as that. The fact that the maximum red is redder, or the maximum blue is bluer is irrelevant.. both screens would still have 256 levels of red, green or blue.

[edit]

Incidentally... some screens claim they are 10bit screens... and many are, but as in all probability you have a 8bit graphics card, so it would be wasted any way.


Also.... "It also says below Colour Gamet 82% (CIE 1976) what does that mean." CIE1976 is just a international standard of clourspace... it equates roughly to around 96% of sRGB, or around 73% of Adobe RGB.

Sorry if it's an uneducated question - but can you plug the above recommendations into an iMac without any problems?

Yep. You can set it to mirror the two screens, work as a dual screen set up, and although I'm not sure about this (please confirm someone) I think you can disable the iMac display and use just the external. All assuming you have the correct lead

I only use Macs (not through choice) at work, so not really an expert, but you can definitely ad a second screen, yes, and a monitor is a monitor.
