Color Uniformity

Now for color consistency, we take our best calibration profile from the very center at 200 nits and test color accuracy at 9 different places around the LCD display in an evenly distributed grid. We’ve shown before that calibration is actually very localized across the display, partly due to the brightness not being uniform, partly due to the discrete nature of the LCD panel itself.

LCD Color Uniformity

It's a bit surprising, but Delta-E actually creeps up somewhat high at the edges of the U3011. When you consider the sheer size of the display, it makes sense, but this is the highest I believe we've seen yet for change in Delta-E away from the center where we made our calibration profile.

    Perhaps. Though you don't need to upgrade to astronomical levels - I bought an HP 2475w (24", IPS 1920x1200) that sits right next to my trusty Dell 2001FP. What's particularly nice is the vertical rez is the same in each monitor. The HP was around 600 when I bought it, but still very nice. Color consistency is a bit better, and brightness is certainly better, but they're calibrated to about the same level.

    Granted, that does nothing to address whether you want more vertical resolution (which ultimately, as a programmer, is what I wanted).

    Nothing will ever be perfect out there, BTW. Just get something that is "good enough" that doesn't cost an arm and a leg.

    The NEC 3090 is a 2006 (07?) design. I can't find it but I suspect the -R model you found for $1400 is a refurb (I bought one when they sold a batch for $1000ish a year ago). The standard model is still $2200, the pricier -SV model just bundles a colorimeter and their hardware calibration software into the package. Reply

    Here is that -R model:

    It's a refurb. You can tell because of the refurb Q&A link in the sidebar, and can confirm by going to the refurb section of their store. That said, NEC replaces teh backlight of their refurbs, and since the backlight is the part most likely to fail you've got almost everything you'd get from a new monitor except the extended warranty.

    to your opening paragraph Brian. The lack of progress is frustrating as hell, there are a mix of interesting techs, but they're all tied up within their own (1080p for the most part) worlds. At the end of the day this is a less 'spec driven' market due to the lack of opacity for most people of the technology involved, but the effects are sad and very transparent.

    I'm still stuck on a Samsung 2443 BW, I would love the colour improvement LED brings, and moreover I'd love as a gamer to have a 120Hz screen - but what I really dream of is a ~27", IPS, low input lag, 2560x1440, 120Hz LED backlit monitor. I'd be willing to pay for it, (or even perhaps a 2048x1152 ~24" variant) but all the dramatic improvements I see seem to be stuck in 1080p, and mutually exclusive of each other.

    Grr - as you say, this is in stark contrast to the CPU and GPU markets. 2443 it is then, for the time being.

    Amed = Amen ;) A very hearty one at that lol. Damn G19 (OMG look my KB pixel density is higher than my monitor's!) Reply

    I myself don't care much for all these 1080 monitors out there for todays 23~27" monitors. I have one of the last Samsung 24" 1920x1200 screen. I still don't care much for the EXTRA-WIDE screen we have today.

    When it goes... I too would love to have a 26~27" which 2560x1440, the text and everything should look crisp!

    Isn't it low-screen instead of extra wide? 24" 1920x1200 is just as wide as 23" 1920x1080. Ya text is really nice at high DPI, check out the latest smartphones next time you are out shopping electric appliances. Reply

    Do the LED screens really have "better" color reproduction? I thought that was only true with the ultra-expensive multicolored LEDs, like the Eizo $3000+ dollar monitors, or the "HP Dreamcolor 2480" type displays? Reply

    Unless it's RGBLED, I heard it's worse than CCFL at times because white LEDs are missing some parts of the spectrum. Reply
