Hey folks, My dad is buying anew dell and doesn't need the monitor. Which would be the most suitable size/shape to accompany my 20" iMac? I dont want to spend too much on getting above the 17" one, so the options would be the 19" standard or the 19" wide. The imac is wide screen however its chin gives it more of a 4:3 shape. I think the 19" wide may sit lower than the imac screen too. Could always prop it up with books! Any thoughts?
