Just curious, if the resolution of my MacBook Pro, circa 2009, has a max viewing resolution of 1440x900 will I notice a difference in viewing 4k video? I ask this since everybody is talking about shooting things in 4k these days and that's great, it's the future, but how many people have TV or computers that can actually view things at this high a resolution? I recently purchased a Lumix LX100 since it was a sub $1000 camera with a 1.7 effective 24-70mm zoom lens but returned it due to a either a faulty battery or electrical problem since it would drain a battery in three days just sitting on a shelf. I want to move into the 4k format but wonder if it is really worth it if I'm not shooting stuff for the film industry that would take advantage of this format. Just thinking out loud here...
