Tbh kezo as for sitting distances, axis, sunlight, glare and lots mentioned is not something that I’ve never considered, ever, nor do I want to start measuring distance or light as the expense for me would be a waste..
I simply place a tv in the room and that’s it, all things mentioned here is great reading, but for me that’s about it..
My Daughter have got a great big TV and all the lovelies to go with it however it’s all a bit to massively huge as I’m simply not used to it so don’t really enjoy the watching experience…
We often have a get together for drinks for important matches/finals whatever, I find it to big, loud and seems over kill imo..
Im happy at about £400ish 43”ish, with no surround blaring or massive giant sized faces on the screen, gaming isn’t important here either..
However even a boring, aging type I realise my TV isn’t up to my tech needs now ??..
