I was tempted by the 40" Phillips ,but it was at the time full retail which I found a little rich so went for a 34" Aoc.
The Aoc had to go back as it had a fault BUT I also realised that for me the width was just too much! - I sit about 2ft 6" from the screen when using computer/gaming and found the width/affect on peripheral vision disconcerting. (Best way I can describe it was I found the width /movements at the edges distracting as I saw something , not sure what , which made me pause and wonder.) Did consider wether I would , in time, get used to it but as it was going back.....
This 'peripheral vision' issue did make me decide against the 40" - too big , too close.
Was VERY tempted by the benq 32" 4k as it looks really nice and I had hopes that as it was 2" less I would not have the peripheral problem but it was at full price at the time and I was not willing to pay £700 so went for Dell 34" but curved! and have found this to be an excellent choice
No peripheral vision issues. Great to look at. Not 4K so not as GPU demanding .
It may be just me , rather than a problem everyone suffers from but be wary!- if I were choosing today it would be either the Dell or the benq ( in the case of the latter with fingers firmly crossed that the width did not cause me any peripheral vision issues!)
