Hey guys, I know this is a rather heavily covered topic, but I have a specific question concerning monitor resolution. Im looking to upgrade my older 20" iMac with an external screen. I want to use between a 24" to a 27", and Ill be sitting 18 to 20 inches away from the monitor. The resolution will be 1920 x 1080. Will the 27" monitor look ok at this resolution(or will it look too pixelated) from this distance? Would it be be better to go with the 24? Any help would be appreciated. Thanks in advance!
