A:Answer If your monitor has DisplayPort or HDMI connections, it will work with this computer. My old monitor was VGA-only, so I tried 2 different HDMI monitors (from the spares in our basement) before I found one which would work with this Dell tower. (Apparently, there are 2 versions of HDMI connectors, and the Dell tower will only work with the newer/narrower version of HDMI connector.)
