If you do not have a spare monitor lying around, you need not go buy a new one вЂ“ simply connecting your computer to a TV that supports video input from computers will work just as well.

Connect the computer to a different monitor.In addition, video cables are also incredibly inexpensive to replace.

Often these programs are running in the background and if available are shown in the Windows Notification Area.What would you do if you were using your computer and the display suddenly went all the way down to the 640X480 resolution (the lowest possible resolution on most computers)? Well, any sane person would assume that their computer is simply on the fritz and, in an attempt to sort the problem out, restart it.
