Depends entirely on how far you're going to be sitting from the screen. I suggest you go to a store, like Best Buy, and try standing in front of various TVs as if they were in your room. In general, a 75" TV is best viewed from a distance of 10-12 feet.
Any closer and you'll notice you can't see the whole screen at once. It's like sitting in the first row at a movie theater - you have to crane your head around to see different parts of the screen.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
