Question: I plan to replace a Thunderbolt Display with this. Is USB data carried through the Mini Display Port, as with the last two Apple monitors?
Document: I was so mad when I got the Dell S2740L 927M9-IPS-LED 27-Inch Screen LED-lit Monitor, I owned them for 1 hour and I had to RMA them (I turn off the light, I saw myself. I kept the light very dim, I saw myself. In general, Dell S2740L is a mirror)- Nice Mini-Display Port to Display Port Cable. Saving $12-$20 to buy 2 of the cable- I love the USB Hub.
Apple Thunderbolt cable ($29.00) would also work.Apple Thunderbolt has a very slight advantage of using the monitor as a hub, but only slight because Dell also comes with a very respectable USB 3.0 hub. So really, when all boils down, the only difference between setting up MacBook Air to Apple Thunderbolt than to Dell is hooking 3 cables instead of 2.The picture quality is great. It has more resolution. Apple's quality was also very good.
When I had it inserted in one of the two rear USB ports on the monitor, I'd intermittently lose connectivity to my devices for perhaps a second or two at a time every few minutes. I moved the receiver to the mac book sitting on my desk in front of me and the problem went away. I moved it to the side USB port of the monitor and it was not as bad as the rear port but still occurred.
I replaced my Apple Thunderbolt first with a similar 27 inch Dell model and then by this one. Most of what is written here applies equally to any Dell 27" which has equivalent resolution to Apple Thunderbolt Display.I was using my MacBook Air with Thunderbolt which stood on a very fancy swivel stand from Rain Design (another $100).
My wife needed nice displays&#8212;more importantly, she needed *large* displays that weren't so glossy. So I inherited her Apple Cinema Displays and she moved up to a pair of these Dell 30&#34; monitors. They arrived in perfect condition, and she's been using them happily ever since. Two months or so now, running maybe 14 hrs/day, and she's encountered no problems. Highly recommended.
2 problems:#1: Took unit out of the box, plugged in to Display Port (with Mini DP to DP cord from my Mac Book Pro (2011)), and it worked OK - ONCE.Now the Dell U3014 won't detect any incoming signal on the Display Port.
The monitor works with 2011 Macbook Pro 15&#34; 1GB 6750M graphics card no problem (use mini-display to display port cable included,  'Google force RGB output mac' for needed code -- alternatively just set sharpness to 0).VERY questionable QC of the display panel. First panel I received had a dead pixel. Second panel has a bright, always-on stuck pixel. This is a $1,000+ monitor.
The reason for this stand is to avoid unnecessary churn and warranty abuse&#34; by the customers which we have observed previously. Customers started to replace the monitors for any issue just to get latest revision and as you know, the display is 100% advance exchange service model unlike platforms where there is possibility of On-site verification.
This thing is godly. How I love being a single man who can spend his money on something so ridiculous as this.I work on Thunderbolt monitors all day, however this Dell U3014 is better by leaps and bounds. The colors are richer, there is so much more real estate for working and gaming. It's controls are easy to use, and it adjusts with ease.There have been some unfavorable reviews due to quality concerns, fortunately this hasn't been the case for me.
I also own an Ultrasharp U3011 (the model this U3014 replaces) and use the old 30" Apple Cinema Displays at work, so I'm comparing it with those.The Good:- thinner- runs cooler- more energy efficient- more modern ports- looks crispier than the old U3011 and Apple Cinema Displays, mainly cause at last they are using a less aggressive antiglare-coating.The Bad:- the LED "backlight" is really the cheaper technique of LED sidelight.
Answer: No it is not a thunderbolt display. You are simply using the displayport2 protocol to send display info to the monitor. You will need to use another wire to send USB, and in my experience so far that does not work. It's a great display once you tell OSX how to display colors, out of the box it's going to look fuzzy and distorted - don't worry, it's just a command prompt configuration setting to fix.
