Oh my goodness I finally fixed my screen noise on my PDA!! I can't count how many headaches the thing has given me, because even though it's not loud, it's very high-pitched! Luckily I already had the programs set up to do it so that my VGA would work. It turns out that one of the preset toshiba screen settings is off - go figure on the setting I use!! I'm a lot happier tonight for sure!! One less thing driving my ears crazy LOL.
