Thanks for the replies...perhaps I don't know the question myself. I understand about screen display size (1024 etc)
I'm thinking in context of the ability of a screen to discriminate high-megabyte photos that will only ever be viewed on a CRT or Flat screen TV or computer monitor.
For example, will a 3mb photo be "seen" on such a screen any different than say a 1mb photo of the same display size?
Thanks again.
