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.
Sorry, there was a problem. Please try again later.Because the PC has a graphics card installed (RX 580), the onboard video is disabled. That's why the VGA connector doesn't work. If you disconnected the graphics card, the VGA connect would work again, but obviously, you wouldn't want to do that. Look for a DP-to-DVI adapter and see if you can connect the monitor that way.
Sorry, there was a problem. Please try again later.You may need to adjust which monitor is plugged in where; try plugging one monitor into the motherboard-based port, and the other into the graphics card port.
