AWOL:
I do wish manufacturers would go back to 4:3 monitors instead of 19:10, since some of us want to program, and not just watch movies.
Just turn your 16:9 or 16:10 through 90° - perfect for viewing those long functions.
Well it depends on having a monitor stand that does rotation (mine doesn't), and an X server that does the rotation at speed (I suspect my ancient Intel graphics driver is rather slow at the translation). I really want a monitor that is more square-ish and for 30-some years, I've used 4:3 monitors and feel comfortable with the aspect ratio.
