  1. @ssamydla Thanks for your information. I think this not problem is, because benchmark score low than my 650m. I also run benchmark in external LCD, Score is perfect. Anyway, I'll try to search other possible answer. Under the current situation, 2012 iMac's can't use optimus. many thanks!
  2. @ssamydla Thanks for reply. My iMac 2012 late spec: Link Some people believe this CPU has iGPU and apple just disable it. BTW, when I disable 650M "no" got black screen In nvidia experience only show GTX970, but benchmark score very low....
  3. @Tech Inferno Fan thanks for reply! My iMac CPU is i5-3470s, I saw it have HD Graphics 2500 (Link) something I get wrong or the CPU for iMac is Special specifications? drag windowed app to internal LCD is good idea, thanks.
