just share my experience

few months ago i bought a sony 40inch tv and use it together with my dell 23inch as it's not syiok anymore watch movie on 23inch monitor

colour - if you use it for general use it's no difference

response time/input lag - TV is much slower than monitor but some TV have like below 20ms its not great but acceptable for gaming

reliability - same, it's all depends on luck..any brand will also break if unlucky..thru the years i lost count how many monitors and tv broken on me..electronis nowadays is like use and throw..nobody make things that last 10 years anymore like last time

to add:

pixel density - 1080p on 40inch tv text wont look as sharp compare to 23inch 1080p monitor, the bigger tv the worst

if you do alot text TV is not good unless go for those 4K tv, gaming depends what kinda games..but if like me abit of both of everything a tv is a good option or best of all use both together lol

yea, watching movies the bigger the better lol i also look at alot tv and dig deep found that sony uses VA panel, VA panel so much better doesnt have the glow like ips so watching movie is so much better

i play world of warships on it and its fine, dont feel any lag just very normal but not recommended for fps

when on dark background or displaying dark scene ips will glow, its like someone shine a light thru the panel

its quite annoying to me, maybe because its a cheap ips panel cheap monitor so poor quality and the glow is much worse

me too, 32 FHD is just nice but cannot find end up buy 40inch
