I've been reading that some people don't like the hi gamut 10bit screens

What is it that people don't like ?

What is the difference with having more colours ?

Any advice as I'm looking to order a 27" soon
 
High gamut screens can produce over saturated colours in some cases, but as long as the screen is decently calibrated then it's not much of an issue in my experience.

A panel having 10bit input support doesn't make it high gamut however and vice versa.
 
yes, dont get colour depth (8-bit vs 10-bit etc) confused with colour gamut (colour space).

Colour gamut is determined by the nature of the backlighting unit used and its spectra. Generally the desktop monitor market will have either:

- standard gamut CCFL (cold cathode florescent lighting) - which offers a colour space approximately equal to the sRGB reference space. this also equates to about 72% of the NTSC colour space reference

- wide gamut CCFL - which has an extended colour space covering commonly 92 - 102% of the NTSC colour space. this is obviously more than the sRGB reference but also covers the other commonly used reference space, Adobe RGB (mostly)

- White LED - this is becomign very common now due to its environmentally friendly status, lower power consumption etc. This backlighting only covers the sRGB space as well and commonly about 68 - 72% of the NTSC space.

- RGB LED backlighting - very rare and expensive but can cover >114% of the NTSC colour space. again much more than sRGB and also more than Adobe RGB


which backlighting type you want generally depends on your uses. most content is built around the sRGB reference colour space, and it is in fact the colour space used by Windows and the internet. some people want to work with extended gamut content in photoshop etc and in other colour managed applications. they therefore need a screen with a wider colour space. if you view standard gamut content on a wide gamut screen outside of a colour managed environment/application then it can lead to colours looking very neon or oversaturated (reds and greens mostly). calibration can help reduce this a little as it corrects the colours being displayed and also corrects white point and gamma. however, it will not fix the oversaturated appearance if you view outside of a colour managed application. some people dont mind it and quite like the vivid colourful appearance. if you arent bothered about colour accuracy or dont have a colorimeter then it may not matter anyway to you? others prefer to just stick with an sRGB space screen (CCFL standard or W-LED) to avoid the issues

some more info here which might help which also discussed colour depth :)
 
thank you ..

i was confusing the 8bit/10bit thing to be high gamut

my uses for the screen will mainly be lightroom and photo editing. tiny bit of gaming and the rest web browsing.

i was thinking about the dell U2711

so if i stick to sRGB space, does that mean im not using the screen to its full potential and might as well not have high gamut ?
 
if you use the sRGB emulation mode on the U2711 then yes, you would be restricting the active colour space and not using the wider colour space. does the content you are working with need to be in wider gamut or is it just sRGB colour space content?
 
Hi Paul




Sorry... :p

Anyway, I didn't think that many applications had full support of wide-gamut (might be getting confused here) so I wouldn't worry about it too much. Also, as it has a switch, you could just test both out and see which you prefer? You're going to want a Dell for that kind of money anyway, and seeing as the U2711 is the only fit, it's really that or nothing?

photos from canon 5D mkii in lightroom (still looking into if these are high gamut or not)

thanks marvin, what you saying sorry for ? ?

well my need is for high resolution so that is why the Dell is in my short list.. The other is the hazro 27" screens also with the same res

You said 'Hi gamut', as opposed to 'High gamut', which led to a hilarious greeting-based joke...
