FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -The Pi’s VideoCore GPU can output 1080p at refresh rates up to 120 Hz-at least there’s a setting for it.

Detailed explanation-2: -Can I use raspberry pi to play 1080p videos on my tv? Yes you can. I use it in my home.

Detailed explanation-3: -Indeed, with two micro-HDMI video output ports, you can even have a dual monitor setup. By default, the Raspberry Pi’s 4K video output is set to a refresh rate of 30Hz.

Detailed explanation-4: -Unless you get the details of the stream (FPS, bit, …) it doesn’t help to speculate if the Pi3 plays them. I can confirm it plays x. 265 at 1080p/30FPS if you have proper cooling for the CPU so it doesn’t throttle.
