      Ruined by Backlight Bleed and Useless Warranty

      • My Best Buy® Elite Plus MemberElite Plus Member

      I really wanted to love this monitor. I've tried LG and Samsung's versions and they weren't quite up to snuff so I happily dropped $1100 on this monitor (I bought it a few months ago, before the price crashed). I was sure that it would be very high quality, and the 3 year warranty gave me extra peace-of-mind. There is a lot to like about this monitor: you couldn't ask for more inputs, the built in USB hub is great, the stand is nice and sturdy and the picture quality in the middle of the screen is phenomenal. Unfortunately, my monitor has MASSIVE backlight bleed - see the photo below. If you want to use this monitor for web browsing or data entry, you will be fine. However if you are a creative professional and there is the slightest chance that your work will entail any colors other than white or yellow, you have to stay away from this monitor. The backlight bleed is that bad. Unfortunately, Dell's service has been equally useless. Their phone support literally hung up on me, and their web support is currently refusing to do anything for me because they made me send them photos of the monitor with a light background under "normal office lighting." which conveniently masks the problem. Sorry to break it to you, Dell, but creative professionals (photographers, videographers, etc) don't use normal office lighting. My studio is kept dim for a reason. And it doesn't matter if bright colors wash out the problem - the vast majority of my work involves dark colors somewhere near the edges. If I could return this thing, I would. But for now I'm stuck because Dell refuses to honor their promise to their customers and I can't ethically sell such flawed product to anybody else

      Excellent monitor for your everday needs!

      • My Best Buy® Elite MemberElite Member

      I was contemplating a new monitor. I was deciding between an ultra wide monitor or a 4k display. After analyzing the pros/cons of both display types, I decided to look for a ultra wide. Instantly this model popped up everywhere I went. I was looking for something that would help my productivity and at the same time improve my gaming experience. The colors on this monitor are professionally calibrated by Dell (they provide a report of the results), which saves you the cost, time, and trouble of doing it on your own. Amazing display. The monitor also has a bundle of ports for you to use, which is a big plus because saves you from countless cables all over the place. The monitor is huge but if you're planning on purchasing a 34" display, you kinda already know that. I don't really have any cons on this display. I'm not a professional gamer so anything i've played so far is excellent (i've recently tried BF1 beta and its gorgeous). I don't use the monitors speakers because i have headphones but if you're looking for speakers, i wouldn't rely my purchasing decision on how they sound on a monitor. I would recommend this to anyone! I was able to pricematch this monitor from Amazon who was selling the monitor for about $150 less at the time. Look out for deals and sales to maximize this beauties value!

      Gotta get this

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      Connected the big monitor to a Surface Pro 3 -- Amazing. don't know how I got by without it. Have three pages up on the screen at once, read mail, browse internet, construct a Web Site. All at once. You gotta see a film like Gladiator, etc. stretched out across the screen. The resolution is insane -- colors amazing, even driven by this thing with a 12" screen. Then in an instant disconnect the cable, close up the Surface and off to a meeting. Would have given it 5 stars but I can't get the built in speakers working. Seems to be an issue with Windows 10. Tried for an hour or so, then the display is so useful I got back to work and haven't thought about the sound since.

      Very Pleased - Work Horse Monitor

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      After burning through a couple of less expensive 4K monitors and reading a good deal about the gsync Ultrawide monitors I decided to try the Dell Ultrawide 34. I have been very pleased. I work from home and the monitor really makes work easier and faster. I have plenty of screen to spread out web pages and documents. There is also the ability to display PIP while working so I have the Apple TV going on one side and work stuff on the other. The other thing I like is the way the monitor is a dock for peripherals. It makes the whole desk area cleaner and consolidates everything into one control center. Gaming is enjoyable. I'm a casual PC gamer and love playing but I am not comfortable dropping $1200 on the Predator. Simply to expensive. I picked up the Dell for half and I am plenty happy with it

      Hesitant but glad I did

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      I really really wanted a 4k monitor and this is just sub 4k. It also has a lot of good features like wide screen and curve that a 4k does not. I was really hesitant to get a DELL monitor because I've had previous bad DELL experiences and always just gone with Samsung or LG. I have been pleasantly surprised with this purchase and it works lovely with my mac pro. I couldn't have found a better monitor, other than price of course.

      Ultrawide is Great

      • My Best Buy® Elite Plus MemberElite Plus Member

      This is a great monitor. The build quality is fantastic, and the stand adjustments are excellent. It is awesome to have so much screen real estate when working with excel spreadsheets, web browser windows, email, etc. The built in speakers are handy for replacing small cheap speakers, but don't expect outstanding sound from them.

      Great Wide Screen Monitor

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      I bought one of these monitors for the office and liked it so much, I bought another for home. Many people use dual monitors and this replaces that kind of setup. The nice thing is that you can move windows around on one monitor without a plastic bezel with the 2 monitor setup. It is a little expensive and I think the prices will come down in the future.

      Great monitor, great price...ALMOST 5 STARS

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite Plus MemberElite Plus Member

      Great monitor. Has a little amount of gloss on the screen which is great. I personally perfer a matte screen. I gave it only 4 stars since it does not support Thunderbolt. It does support mDP, which still is ok, but cannot daisy chain thunderbolt devices like the more expensive LG Ultrawide. If this is used on a PC, then full 5 stars. Only 60hz no freesync or gsync.
