Pros: I love opening PDF's with 2 pages open on one screen and having it display properly.

Amazing picture, no dead pixels. Everything you'd expect from a 4k monitor. MNW Global delivered incredibly fast shipping from Korea, and near instantaneous support to the only problem I had discussed in cons. (Korean Language Barrier and travel adapter)

Cons: For the Monitor: The stand is total garbage and this monitor has no VESA mounting holes. I will have to machine my own bracket to attach it to my mon0price mounting arms. Frustrated that Samsung overlooked something so simple on a bleeding edge product.

Windows 7 support for 4k isn't quite there yet. You'll spend a lot of time resizing windows to make use of the space the monitor provides. Most websites and other content aren't set up to display on a 4k monitor well like at any given time 50% of this monitor is being utilized as a white light bulb on most pages.

FOR MNW GLOBAL:
Unfortunately, the monitor is preset to be in Korean, all documentation and instructions are in Korean. The $700.00 monitor showed up with a $2.00 travel adapter to plug it in to my wall that wasn't intuitive and didn't seem to fit until I really jammed it in there. MNW helped me figure out I needed to jam it in.
So room to improve:
Include a url even just printed on the paper packing slip to the pdf of the English manual.
A link to a step by step guide with pictures of navigating the on screen menu to change the language setting to English. I figured it out by stumbling through the menus for a while.

Other Thoughts: Besides that I'm happy with the purchase, and extremely happy with the shipping time.

Pros: None yet.

Cons: All manuals are in korean. It came with a korean power cord with korean prongs and a cheap travel adapter that DOESN'T even fit the korean prongs.

There was no warning I wouldn't receive a US model or a model capable of working in the US without modification. For $700.00 I don't like having a sketchy workaround travel adapter as part of my system even if it worked.
