Ok so I'm looking for a big ass TV for a couple of months now and one shop discounted their ''Philips 55PUH6101" by 30%. I didn't even look for 4K tv but this one is currently cheaper than any Full HD tv with similar specs on the market, so ofcourse I'm intrigued to buy this one.
The only thing I'll use at 4K is a possible PS4 pro after a few months.

The only thing I'm concerned about is the refresh rate. Every time I google about it I find comparisons about 60Hz vs 120Hz vs 240Hz. However, most tv's I look at either don't have Hz written anywhere, or it's either 100Hz or 200Hz. This ''Philips 55PUH6101" Doesn't have refresh rate written anywhere either, I've found one website that says that it's 100Hz.
Now first of all I never tend to believe anything that I can find on only one website.
Second of all, if it truly is 100Hz, What does that mean for me? I can't find any information about this specific number, I see people questioning the same thing but the answers are always about 60Hz or 120Hz.

So please if anyone can answer this Hz question for me, should I be concerned about it and maybe you know the true refresh rate this tv has? is this tv worth buying? Will it look good with PS4 Pro connected?
