I think so yeah
This is one I bought

they are pretty common.
I have that plugged into the amiga monitor port, then a male to male VGA cable to the converter thingie, which then plugs into my LCD.
Has anyone thought of using a multiport vga switcher hooked to different Amiga's with the output fed into the converter, then to a single LCD monitor? Would be cool to switch from A1000, A500, etc just by hitting the button on the switcher.
