stretched screen on Mac mini
Hello, I am using a mac mini (2010, 2.4Ghz) connected to a 24" Samsung monitor via a VGA to HDMI converter cable in Mac OS 10.9. About half the time when I awaken my computer from sleep, the screen is "stretched" to much wider than its normal size. Putting it back to sleep and reawakening it fixes the problem, about half the time. So far I have tried resetting the PRAM, which did not work. Any ideas? Thanks, Fred
