I would like to know if there are any video formats I should avoid when testing an Apple Monitor //.
Specifically, I would like to know if it is safe to test a Monitor // with devices other than an Apple Computer (e.g. a VCR).
While optimally I would prefer to test it with an Apple computer, I ask this question for a circumstance where that is not possible, such as if I find one at a thrift store.
I would also like to expand this question to include the other Apple monitors used with the Apple II series, but the Monitor // is my main interest.
Any information would be appreciated.
