Additional Tips:

1. What are the PC/Mac system requirements for 4K playback?

I can give you some data points as I tested multiple configurations to find out myself. My requirements were 4Kp60. The tests were done using a 4k capable monitor connected via displayport (the monitor however was not mine). I tested this a few months ago, I believe.

Tests, in order of memory:
i7-4770k using integrated GPU: 4k@60, no issues.
EVGA nVidia GTX 750Ti: 4k@60, no issues.
i7-2600k using integrated GPU: 4k@60, no issues.
G540 Celeron CPU (2013 CPU) using integrated GPU: 4k@30 no issues, 4k@60 a slight slowdown during high action scenes. CPU was pegged @ 100% for majority of the scenes. I believe that this chip is using the same integrated GPU as the 2600k, so it may have simply been an issue of the performance capabilities of the chip.
EVGA nVidia GTX 680: 4k@60, no issues.

Of course, source video encoding is the most important aspect of these tests, so I tested with three sources:
Youtube 4k video scene (VP8 codec, I think?)
Netflix, House of Cards S2,Ep1 title sequence (Silverlight? Windows 8.1 OS).
Some random MKV that I don’t remember the codec of and I’m not sure why I mentioned it.

Conclusion, most modern GPUs and Intel CPUs can handle the scenes relatively well.

2. Some guys recommend third-party 4K video player apps like VLC, DivX Player, Media Player Classic, but all of them can’t be an ultimate solution for all 4K videos. Based on out testing, we found VLC can’t support 4K video well, Media Player Classic can play 4K movies but only on Windows… To have a smooth 4K playback on Mac/Windows, this professional 4K Ultra HD Video Converter is the best choice.
