But you will be limited to the native Amiga resolutions, colors, and speed.
Technicly correct, but some of the supported resolution would be 100% unsuable with any monitor if it wasn't for the Indivisions due to extremly low refresh rates.
Also since the Indivison-ECS is (allmost) complete Denise-replacement getting all raw data Denise gets so it's possible to missue is as some sort of advanced chunky-framebuffer doing quite well on some games adapted to it.
The Indivison-AGAs on the other side sit on the digital-output of Lisa and are less flexible/suitable when it comes to these thinks (but AGA does allow greater bandwidth anyways, so the results are similar).
