How is a North American PS4 different from a European PS4?

Like do they run at different frame rates, use different color spaces, etc.?

@babylon7: The power cord is different.

The European version is little more polite and it's nucking futs for soccer.

@GTR12: Yep, just the power cord, everything else is 100% the same.

All PS4 systems are region free, you might only need to be concerned on the power cables & Blu-ray region might not be region free.

At least PS3 systems were not region-free for Blu-ray movies.

is it real that you said all ps4 systems are region free but there may be some obstacle in region . however can you give me more idea about it that i am looking for so that i can use it region free that will be the best service for me .thanks for your kind information.

It's as I said, there are no obstacles. Games from all regions will run on your PS4 system, while Blu-ray movies might not - I haven't bought a PS4 until now but I know this info from testing with a friend and I have previously faced this on my PS3 system.

My advise is just go for the local region you're living in to avoid any hassle with plugging in your power cables.

I had went for a PS3 NTSC back then because I used to usually buy Blu-ray movies via Amazon US & have them shipped to where I stay. I stopped doing that, it's all movies via digital download now for me.
