I'd like to know why LCD displays that have the "Auto" button need it in the first place. Are they losing sync with the signal because of some special feature or all LCD displays really suffer from this (because I don't remember having that on CRT monitors)?
Or maybe the video card's signal changes?
My desktop PC has its monitor connected via D-Sub port and sometimes the screen gets blurry and I have to press "auto".
On my netbook, there is no "auto" button and the screen doesn't seem to ever blur pixels (I assume there is some kind of special connection between motherboard and display that doesn't have this problem).
