Rated 4 out of 5 stars
Is ok for 4k
This monitor isn't for everything. Make sure your computer can support 4k @ 60hz.
* When connected to 15" macbook pro (mid 2014) it allows pretty good scaling options.
* When connected to my 13" macbook pro (mid-2014), the scaling options were pretty limited and everything were pixelated. I wouldn't not recommend this monitor to 13" macbook pro users.
* When connecting windows desktop (r7-260x)
1) HDMI was able to drive 4k, but only at 30hz and caused serious lag.
2) Displayport was able to drive 4k @ 60hz without any lag.
It's a great monitor for those who is looking for 4k.
