I got my imac to mirror to the 40" lcd tv. It seems fine n worked. BUT, I dont want to have the imac screen on and just want it on the LCD tv. Anyway around this? Im using the mirroring option My imac is 1680 x 1050 my lcd is 1360 x 768 When in mirroring mode, The resolution is fine on lcd but on the imac its degraded to like 1024x768 When mirroring is off,my imac is back to normal on display but the lcd just shows the wallpaper n nothing else but the display settings window. But If i can get the imac to not show while the lcd is on,that would be great since i dont want to have both on the same time.
