if it can be displayed, it can be copied.
One way or another any content can be copied. ANY. It may not be a bit-exact copy, but it will be a usable copy.
If it can be displayed on the screen then a screen recording software can copy it. If the video card has a S-video/Component/Composite output it can be copied. Hell my capture card can do even HDMI in 1080p.
