I own two U2415s; the second one came yesterday and is still in the box b/c my new GPU hasn't arrived yet...current GTX670 isn't enough to drive the 3840x1200 res with the eye candy I want. Anyway...
A few weeks ago I was looking for a replacement for my (very) old Dell 2407 WFP (yeah, it was that old). The backlight developed a flicker that was getting worse, the colors had gotten washed out and the power button had stuck down in the ON position probably 2 years ago.
I wanted to stick with Dell b/c I had really good luck with the old monitor and liked it very much. The monitor is arguably the most important piece of hardware in the whole system b/c it's how you interact with your computer. If it hurts your eyes or doesn't do what you need, you will not be happy.
I started searching and came across the U2415. It was pretty much brand-new on the market and there were maybe 2 reviews I found, both positive. I figured I'd take a chance on it, based on my previous success w/a Dell monitor.
I take a lot of work home and spend a lot of time in almost the entire MS Office Suite. I also game probably 10-ish hours a week, total. My "movie watching" on the PC consists of YouTube vids, mainly.
I had read that out of the box the U2415 was "99% Adobe color gamut" or something like that...basically, factory calibration was very good. I hooked it up via DisplayPort, installed the Dell DisplayManager software and the driver and have been very, very happy since. I bought a 15" LCD back in God-knows-what year and know what input lag looks like. No such probs that I can see. I'm not a graphic designer and I'm not measuring for the 99.999th percentile of the grayscale. That is important and valid for some users; not for me.
I use my monitors as computer monitors; I sit right in front of them and do what I have to do. I haven't tried watching a dark movie from a 178-degree angle to the left, but I can tell you that I don't see any backlight bleed on darkish screens in my darkish room.
I've been playing Skyrim and Far Cry 3 since I got the U2415 and have been very happy. The ultra-slim bezel is the reason I decided to get a second one and try dual-screen gaming again. Tried it in the past with old 19" monitors that had like a 1.00-inch bezel and hated it. That was a 2.0" gap of nothingness in the middle of my screen. I got fragged quite a bit.
So far I'm very happy with my U2415 and opine that I'll be happy with the dual-screen setup as well. IIRC, I bought the old 2407 in 2006 and it didn't start to crap out until around 2011 or so. That's a pretty good run. If these last as long, I'll be very happy.
Hope this dissertation helps.
