Hey all, I have a 27" 2011 iMac with the 2GB graphics. I've got a MDP->HDMI adapter hooking up to a 40" Samsung LCD whose native resolution is 1360 x 768. However when hooked up to my iMac, using that resolution results in a green tint. Changing to 720p in display settings fixes the tint, but the actual display goes off the edges of the screen (overscan). I would much prefer using native resolution. The weird thing is, when I hook up the adapter to my 13" 2010 Macbook Pro, I can use the 1360 x 768 resolution just fine, with proper color etc. Any suggestions on how to fix this on my iMac? Both have clean installs of Lion with 10.7.3. Thanks!!
