    Accurate colors. Sharp gray-scale. Powerful audio. Lots of features.

  • -

    Expensive. No side-mounted USB ports.

Dell’s U3415W is the best 21:9 monitor we’ve tested so far. It offers superior contrast to the LG 34UC97, and while it falls a bit behind in color accuracy, it’s otherwise on par. The stand is superior, too, which makes it better suited for the professional image and video editors who are the target...

The combination of a large diagonal foot print of 34 inches, a resolution of 3440 x 1440 and the 21:9 format has become a high-end favorite on domestic desks in a very short period. Primarily, the large image area is the reason for this.

    Attractive housing, Good image quality, Curved display, Multiple connectivity options, Low DeltaE

I bought two of these for myself & my wife as combined christmas & birthday gifts, we are both happy camps now. WE LOVE Them! Sale price rocked too.

  • +

    Heavy duty construction, awesome clarity, multiple interface options, multiple cables included, superb packaging, this is a wow in every way.

  • -

    The only minor complaint I can possible squeeze out is the difficultly in connection to the built in usb 3 hub, it is on the back under a cover plate that is difficult to access without turning the monitor around.

This monitor is a dream. The brightness on it is spectacular. Is has auto brightness and color switching for different programs and it works seamlessly. The backlight bleed in the corners is over exaggerated in many reviews. I have not had a problem with it.

Wow! I conducted quite a bit of research before buying this looking at other name brands from Samsung and LG, etc. Overall, they had similar specs and reviews. The Dell U3415W however stood out.

10 May 2015

I read through a bunch of different reviews on similar monitors and finally settled on the Dell. I've always had a good experience with Dell monitors and even a 22" I bought probably about 10 years ago still works great. There were a lot of posts about light bleed.

Big display and perfect for having 4 screens up at once.
