You can use a Sony PVM with RGB inputs. But you will need to make a
cable for your coco as it uses BNC connectors. Also you will need to
change the coco3 as well for negative sync

They do not handle AGA "double" screen modes, nor will they display the interlaced output from the A2320 Amber board or the motherboard interlarded output on an A3000. However, they will show all normal 15.75 kHz displays, and many (most? all?) of the 1084 versions have a separate input for composite video.
