Thanks 4 your reply.
Yes, bios is showed before mac os.
1. Not interest yet
2. I do not have a second monitor. I want to keep my monitor anyway.
3+4. My Apple cinema works as expected at full resolution, the problem is only at boot. No need to look for adaptors, hdmi, etc.
5. Not interesting.
I am a mac user, not care about windows.
I made this hackintosh cos i could not find a proper mac (price is a issue)

Thank you anyway for your time.
