Like Pan1k said, the Easy-VGA does not go on the CV643D. I have a CV643D too and the CV643D connects directly to a PC monitor and will display Cybergraphic modes (for example my Workbench, Word processor, etc). You'll still need your native Amiga video port with the Easy VGA either connected to a 2nd monitor or use a video switcher to connect the Easy VGA and the CV643D to the same monitor and select the input via a switch when you need to use native Amiga screens for things like games or non-promotable screens.
