As indicated in the Title, I do not know the video outputs shown in the attached image. In one the monitor is connected. and the video board has a total of 4. It is not possible for me to access the inside of the equipment or gossip the operating system, since it is a workstation for Medical Diagnostic images.

Hello friend try connecting HDMI on the graphic or one DVI. If you have a VGA connector, get a converter for the large black input that is below the red box you put. I hope it helps you.

Obviously I will have to visit the ophthalmologist. It's HDMI ... I don't know why I saw it another way. Thank you very much to all.
