Hi, I'm not technically savvy and I have a question that will probably be very simple for many of you to answer. When my dad's computer was hooked up, the screen displayed a very wide view, and the print was very tiny. He has Windows XP. I clicked into Control Panel, Resolution and observed a sliding scale I could choose. I slid it all the way to the left, and inadvertently choose to keep it that way. Now the screen is so huge, I can't view it in its entirety, and I can't access that same sliding scale to change it back. After you finish laughing, can you tell me what to do about this? I apologize in advance for the stupidity of this question, and ask for your mercy and your help. Thanks.
