Are you more interested in observing photographic properties, or in experiencing a photograph? I'm not trying to be 'judge-y', just curious, is all.

Then, there are the various metrics pertaining to the output to consider.
My son told me not too long ago that he often streams movies on his phone with whatever ear buds are at hand. How big is your screen and how many channels does your sound system have? Does it matter? To be honest, I won't watch a horror movie no matter how lo-fi the system, because I know I'll be scared out of my mind regardless and will have nightmares for weeks.
