Do I Need an Original Monitor For a Mac II?

I found someone selling a Macintosh II on Craigslist for very cheap, in supposedly working condition. I figured that since it used analog rgb video that I would be able to use a small adapter to VGA since the only Macintosh I have right know is a Macintosh Plus, which obviously doesn't have an external monitor, and the guy selling it didn't have a monitor either. When I looked at the pinout for the connector used by the Macintosh II video card, it had red, green, blue, hsync, vsync, and ground, just like VGA. But, after some more research, I found that the video signal is 66.7 Hz. Would I be able to use an adapter with a modern monitor or not?

I can tell you from memory those converters to use standard PC monitors are a nightmare to get working correctly. You'll save yourself a lot of grief by just finding a compatible Apple monitor from that era.

I suggest first figuring out which video card is installed. There is the lower-end Macintosh II Video Card and the higher-end Macintosh II High Resolution Video Card.
