A:Answer Yes-
DVI-E, HDMI, and DISPLAY PORT are are digital signal. They support true 1080 - caviat (DVI-E only supports 1080i)
HDMI and display ports will support 1080p and display port goes into 4k
that being said, VGA is dead back in the 80's I wish people would get this term right because VGA doesn't exist anymore. these are SVGA you are referring to. and it is analog. physical port/cable adapter will not work. you need a converter (analog to digital converter) for the SVGA port to receive the signal. they are available, but money better spent on getting a better monitor.
