Question -- tried googling, but to no avail. I have a Mac Pro 1,1 that I'm using without an attached monitor (has an ATI 4870 GPU)...I'm using either Apple's screen sharing, or LogMeIn. I can't get the screen resolution any higher than 1680 x 1050 (or something like that). Anyone know how to get around this, or why this happens? Thanks in advance.
