I'm using a Dell Ultrasharp 2410. The 110% gamut has a dramatic effect, and I can see tonal contrasts in deep shadows and darker colors that I would never see otherwise. It was a bit pricier than most Acer models, but absolutely worth it. Unfortunately, it looks like Dell isn't selling these any more (just the cheaper and lower quality 2412).  But if you see a 2410 for sale somewhere, it comes highly recommended.

@Moriador I've too DELL Ultrasharp U2410,I've bought this as used,but is like new and for price which I've took without the question(£80),but still I still looking to upgrade to above Crossover 27Q LED-P Pivot edition,seen this monitor how it performs and used this monitor in 3DS MAX and Photoshop for while and must admit difference is there

Thanks,Jura
