I'm using a Toshiba Satellite A105. It works good and I've upgraded everything else I can, but the screen resolution on the oem screen is not high enough for some of the work I do. I have to keep adjusting sizes and scrolling around to see what I need to see. These same files are easier to read on my higher resolution work laptop. I would like to upgrade to at least 1680 x 1050. Is it possible to upgrade this screen?
