Excerpt: I mostly use this with Lightroom and sometimes Photoshop. Photos look amazing with this monitor. I had to adjust the text size in WIN 7 to 125% - 100% was too small and Large (150%) is too big. I used the custom menu picture adjustments versus the presets I have a NVIDIA GeForce GTX 770 video card and the display port connection works well and runs this resolution just fine for me
Pros: Easy To Set Up, Easy To Use, Menus Are Easy To Use
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: Here's my $0.02 from a guy who just bought this monitor. I just got it last week so my time with it hasn't been extensive yet. Having said that, you will probably not have any problems with 4K with your graphic card if it's a fairly modern mid-high range card. My rig specs are as follows, an i7-930 CPU @ 3.0ghz, 12 gb ddr3 RAM @ 1680mhz, 780ti GPU.
Pros: Beautiful large monitor, crisp colors and excellent overall image quality. Much has been said about the poor monitor stand but I don't really have a problem with it. It sits stationary on a relatively sturdy desk.
Cons: It doesn't make me breakfast in the morning.
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...
