Hi, I've been trying to use my iMac as a secondary monitor from my Macbook Pro. I've tried screen spanning doctor, and got it working, but the refresh rate on the iMac seems off, when moving something on the iMac or putting any kind of moving media on it, it gets very blurry, leading me to believe it's the refresh rate. Connecting them to each other and to the same network seems to have the same refresh speed, so I'm wondering if there is another way to do this rather than just to use screen spanning doctor. I'm pretty sure I used ethernet and not a firewire so it could just be the slower speeds causing the problem, but I don't know if a firewire would even be much better simply because the difference between connecting the computers both to a network and directly connecting the computers is negligible. Anyway, just looking for some help on dual monitoring these two, thanks.
