Also you can't trust even positive reviews on sites like Amazon. Someone reviewed that the Samsung 4K ips display worked with a new Mac Pro yet I've gone through two and both flicker uncontrollably with my Mac Pro with D300s.Right now my advice is stick to the supported screens on Apples site or the few newer models such as the Dells that various members have reported working. The biggest compliant about 4K is MST issues with sleep and waking or poor color uniformity. I originally picked up the LG cinema 4K that runs at 50Hz and half the screen was warm while the other was much cooler
I've been using Amazon for reviews for almost 10 years now, and you can definitely spot fake reviews. For the most part, in my personal experience, you CAN use Amazon reviews if you choose the right reviews to believe. I personally have reviewed dozens of items on Amazon and have been 100% truthful. Of course you will sometimes find incorrect info, but Amazon has millions of reviews which are helpful.
I've been unable to get this display to function via DisplayPort. It's only working for me using HDMI, so it's stuck at 30Hz. Trying to use it with a nMP. Aside from that, the display seems quite nice. I'm not seeing any color uniformity problems.
Edit: Finally got this going. The trick was to hook the display up using both HDMI and DisplayPort. Then OS X saw it as two displays attached at the same time. Then I was able to unplug the HDMI and it seems to be going fine with just DisplayPort at 60Hz. Reboots work fine now with the normal caveats of no display until the login window and unable to use FileVault.
Curious to know what settings & calibration you use/d for this monitor (BL3201PT) under {10.10.04}. And if you found the "M-Book" (display) option useful. Or the "Low Blue Light" mode. Thanx.I still have it and I'm still happy with the display. Running 10.10.2.
