Can't seem to get HD display on my new second monitor.
Just bought an LG 22" monitor with native 1920 x 1080 resolution. Hooked it to my new 21" imac via the "mini display port-to-VGA adapter."
The new monitor itself pops up a window saying "switch resolution to 1080 x 1920 for best performance" but on the apple VGA display window, the list of available resolutions tops out at 1600 x 1200, and even if i try this one it says "D-Sub out of range" and goes black. I do have it set at 60 Hz.
is this a VGA limitation? bottom line: can I get this monitor to work ? I don't feel I should have to buy a thousand-dollar apple cinema display to have 2 monitors.
