Dell U3011 Review: Dell's New 30-inch Flagship
by Brian Klug on January 13, 2011 9:17 PM ESTColor 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.
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.

When is Dell going to start offering LED backlighting for it's UltraSharp lineup? 24" 27" and 30" We are waiting!cjl - Friday, January 14, 2011 - link
The thing is, WLED backlighting is actually worse image quality than CCFL, and RGBLED is both expensive and still has problems with lifetime. All the lower end monitors love to advertise LED because it sounds great and new, and it's definitely the way to go if your goal is low power consumption and heat. However, for the absolute best display quality, CCFL is the way to go (unless you go to the insanely expensive RGBLED screens).Pessimism - Friday, January 14, 2011 - link
CCFL=FAIL.Have you placed a year old CCFL-Based laptop next to a brand new one? You'll see a large drop in brightness and a noticeable yellowing of the picture. The manufacturers use the cheapest CCFL tubes humanly possible with short-lived phosphors. Additionally they make them near impossible to access to replace, when they could easily place them behind a removable panel with a quick disconnect connector to replace them.
I'll take my chances with LED.

We aren't talking about laptop backlighting here.cjl - Friday, January 14, 2011 - link
Yes, laptops use short-lived, cheap CCFLs. This isn't a laptop. High end IPS monitors use high end, wide gamut CCFL backlighting which is much better quality than any laptop backlighting (and also more power hungry, which is one of the reasons it's not good for laptops). Have you ever seen a high end CCFL backlit monitor? They absolutely blow away WLED (which is what the vast majority of LED screens use). RGBLED would be nice, but as I said before, it's both quite expensive and it still has a few unresolved issues.semo - Friday, January 14, 2011 - link
Yeah would have been nice to see RGB back lighting on the latest, greatest and most advanced display of a company's lineup. This thing won't be replaced for the next 3 years at least I would imagine.Anyway, I would prefer 3x 24" monitors instead of one or two 30" if I had the money to burn.

I have a 30" and 2 20" 1200x1600 panels on my main system now (all bought before eyefinity was an option). I don't think I could ever go back to a smaller main screen. I makes my 22 (1680x1050) and 19" (1280x1024) combo at work frustrating to use at times. For everything except eyefinity gaming I'd recommend one 30 over 2 smaller screens; and I suspect most people who can afford a 30 will also have at least one additional monitor hooked up.DanNeely - Sunday, January 16, 2011 - link
The replacement time probably will depend on when a significantly better panel becomes available. The 3007 was followed by the 3008 when a wide gamut panel was available. Nothing major changed on the next few years, so Dell didn't do a refresh until this year. And at least on paper the only thing that really changed was the addition of 10bit color, and the addition of a 2nd HDMI port in place of several legacy connections; I suspect this refresh had more to do with 08 looking like an obsolete model year than anything else.An RGBLED backlight that lasted long enough and that didn't break the bank would be grounds for a major update. A USB3 hub or Lightpeak support could trigger another minor refresh next year. If the memory card reader only supports SDHC an SDXC update could trigger a new minor revision as well.

I'm still debating myself with getting the U3011 or ZR30w, reason being I do game often.But lately photo and video editing has been in the picture more and more. And of course I'd be watching movies too ;)
Decisions, decisions, it's a love hate thing,,, lol

Thanks Brian. I was just about to comment on the lack of NEC models in your comparison charts. I know I will be upgrading soon and a monitor is so important. I spend so many hours a day staring at this device that it makes all the difference when you have a high-quality display.
