I'm new to here so I'll probably do something wrong but I have everything hooked up but i got the adapter to display things on my moms dell screen and make things bigger so i could see more then just 13" but it's square shaped so when i have the display good it is in widescreen witch i hate but the furthest out one that isn't widescreen is too zoomed in so how can i adjust it so that the wide screen is gone the orignal display is 1280x 1024 i think any help would be great thanks
