My computer always shows a 1280x768 resolution after the installation. The problem is my monitor is a 15" (1024x768) and it turns up blank after completing the installation. I have to hook my computer to a 17" to change its resolution to fit my screen. Its annoying and heavy. I've checked with my computer guy and he says its something to do with the BIOS but he doesn't know enough to change the settings. Does anybody here knows? This thing has been going since I bought my computer.
