So I was looking to purchase a GTX 1050TI for my current pc which is connected to my 4K Samsung 6400 40" tv. My current graphics card (an old AMD one) only goes up to 1080p and therefore doesn't take advantage of the full TV res. I mainly watch movies and 4K content on YouTube so no gaming at all. My main question is what HDMI lead would I have to buy i.e. 1.4 or 2.0, I'm confused? & will the 1050ti be sufficient for 4K movies/ streaming? (My internet connection is good) I know nothing about all this so any help would be appreciated, thanks!
