I understand
In truth my 32inch for gaming I think is too small I move the sofa closer so I can see things easier, as I am used to gaming at a PC desk.
At the same time tho 65 would be too big, for me I think 42inch would be ideal for gaming, but my living room is quite small I live in a small contained flat.
After I got a 27inch monitor, 22inch "feels small" now for pc gaming

My PS3 is hooked upto a 22inch next to my 27, the xbox 360 is hooked up to my 27. PS4 i hooked upto 32inch tv in living room.
What I really miss tho when gaming on my PS4 is the sound from headphones, I think its a lot better to play with headphones than TV speakers. I did consider moving the PS4 to my bedroom where the PC and other consoles are but I dont think I can make it work, another console would have to move out and the lack of analogue out on the ps4 is an issue as well.
