Looks like the GW2450HM is a good deal if you don't care much about accurate color. Its primaries seem to be quite a way off what it should be. It excels in every other area though so if you don't do any photo editing, it should be fine for you.
I do photo editing in adobe lightroom but I am not a pro just an amateur photo editor.Once calibrated the dE average was reduced to 0.8. This would be classified as excellent colour fidelity by LaCie
The calibrated settings of tftcentral are pretty pointless for us cos we don't have 1000$ colorimeters. What you'd be getting is a pretty poor out of the box dE of 3.4. Also the dE is roughly 0.8 after calibration which to anyone who's worked in the print world is piss poor. You'd expect something in the range of 0.3 or lower. Pro monitors from Eizo and NEC have a dE of 0.1 in adobe RGB which is a much larger color space than sRGB.
If you wish to do any sort of photo editing, I'd not recommend this. The green primary seems way off in the CIE plot.
If you think dE of 3.4 is poor for colours that means Dell U2410 (dE 6.7) and Dell U2412M (dE 3.2) would have bad colours too. What model is good for colours under 12k budget?
Not sure of the U2412 but since the U2410 is a wide gamut display which is factory calibrated to Adobe RGB, its out of the box sRGB performance is piss poor. This is very well known - anyone buying a U2410 will know this.
What about poor black levels (0.17) and contrast (770:1) of U2312HM? Doesn't it bother much?
Neither of those matter too much for a computer display which you'll be sitting 12 inches away from.
List price is 12,500. Purchased it frm shopclues which claims to offer 3 percent discount...cost me 12080 by applying coupon for 100 rs discount... did not opt for COD...purchased by card to get 2 percent credited to account.Cost of the benQ??
