I just purchased a Viewsonic VX2035wm monitor recently. The monitor has both DVI and VGA inputs and my video card has both dvi and vga output. I have connected my monitor to the computer through dvi but I also have to connect my vga cord to the monitor and computer or it will not display a digital image. Through the input selection digital is selected so it is coming through the dvi cable but I have to have the vga cable connected. If I unplug the vga cable after starting up the computer the image stays on the screen. However that isnt really the problem, I am trying to connect my xbox 360 through the vga port and it works but I can not switch between my computer screen and xbox 360 screen. Can I only have one compnent plugged in at once. I was thinking I should be able to switch between the two with the press of a button. I know this is really quite confusing but any help will be appreciated thx.
