Dolphin and fullscreen resolution issues - a little help please

[LordBarker]

I have seen a similar topic posted before, but none that can seem to answer my exact question.

I am running Dolphin on my iMac on Windows 7 via Bootcamp all games run perfectly in their windowed mode, however when in fullscreen mode they run slow. Ok I thiught is obviously the fullscreen resolution - which on my iMac is a whopping 2560x1440.

However if I drop the fullscreen resolution on Dolphin then half the image is cut off!? Also changing my windows desktop display resolution doesn't seem to help. Can anyone tell me how to make the image display properly on fullscreen - even with a low res as I just want full speed emulation.

Cheers
