Excerpt: This monitor works well with my Mac Pro 15 on Display Port connection, but very slow on HDMI port. Some times mouse does not even work. I am a developer, most of the time use this monitor for development IDEs, so that I can get good real estate. I do photo post processing as well sometimes. Good thing is Mac OSX and Windows 8.1 works pretty good on Display Port. My VM (Windows 8.1) on Mac Pro sucks, have to change my display settings every time I reconnect.
Excerpt: The Samsung display looks good, the image is solid. It is cheaply made and flimsy. A ton of plastic made to look like metal. It doesn't play great with the new Mac Pro. It will only fully work at 30Hz via HDMI. This is a real disappointment and I'm hoping Apple can update things to allow a 60Hz fully functional displayport connection. But it isn't bad for the money.
Summary: This is a great monitor. I love the resolution. The only problem I have with it is that they didn't put much quality into the stand. Even the slightest vibration makes the monitor do a bobble head like shake which can get quite annoying. It also doesn't appear to have standard mounts, so using a third party stand for multiple monitors looks like a no go.
Summary: I'm not entirely sure it's the monitor but half the time it sleeps it fails to come back and I need to cut the power to get it working again. I'm not sure what the source of the issue is until I can get different hardware to test with but I got a MacBook Pro connected via HDMI (can't do Displayport, the Mac apparently doesn't do 4K on that) and half the time the display sleeps it fails to come back (normal sleep is blue light blinking...
Summary: Colors and sharpness looked pretty awesome while in a game on the part of the screen that was actually working. Monitor looks like crap on the desktop and from different viewing angles. There is no way I could spend all day working in front of this thing. I opted to return it because of the washed out colors and poor viewing angles and instead went with the LG 34 ultrawide IPS Panel. If you are just using this for gaming it would be ok, for the price.
Summary: I usually sit in front of a screen for 10+ hours a day. I'm a programmer. A display for me is very important and I usually don't mind paying a premium for something that is worth it. As you can imagine I'm not afraid of technology and don't mind trying a new product even if I'm amongst the early adopters. I'm using the monitor on a late 2013 MacBook Pro (with the geforce GT750m card) - running OS X 10.9.3.
Early adopter, nice monitor but displays light bleed on the edges

Summary: I preordered the monitor and received it about a week ago. I'm using the monitor with a Late 2013 Mac Pro and OSX 10.3 which supports 4k monitors. I'm noticing a blue-colored light bleed along all four edges of the LED display. Other than this, the 4k picture is amazing and OSX 10.3 supports the high resolution amazing, looks like a Retina display!
