I dont think the MBP will give you any problems, but i have a feeling your BRAVIA might. If hooking up in PC mode, the BRAVIA will not allow you to use the full 40" of the screen, it will only let you work with about half of that and the rest has a black border. I tried hooking up my PC with quite good graphics card about a year ago to my BRAVIA 40" with a VGA cable and this is what happened. I read somewhere this is because the BRAVIA limits the screen for some reason so you cant use the whole screen when in PC mode. I haven't done extensive testing tho with my MBP so there may be a way to get it work. In fact I'll try it and post on this thread what happens (might be a couple of days tho).
