Okay so here's my scenario. I wanted to use a screen saver which is a cool clock since I do not have any alarm clock or anything in my room, and being that my MBP is always on, why not make it a clock when im not using it? I was wondering if it would be detrimental to my screen if I never let the display sleep and leave the black and white clock screen saver on all the time? Would it really make THAT much of a difference to the life of my screen? Thanks in advance for any responses! Any suggestions on the best settings to use to most save the life of my screen while doing this?
