018- What is the usual way to connect an Apple II to a display?

For a IIgs, you connect to the IIgs RGB monitor. For other Apple II's, you use a video quality 'RCA cable' to connect to a composite color monitor, such as one of the Apple II monitors or a third party monitor like the Amdek Color-1. (The IIgs has a composite color output which can go to a composite monitor; but, for IIgs super-res, the results are unsatisfactory.)

An alternative to a composite monitor is to connect to a color TV directly or through a VCR. Most VCRs and many modern televisions have a composite video input port. Rather than buying a new monitor, a person can usually use an RCA cable to connect the Apple to a spare VCR or television. The stabilization logic built into even a cheap VCR can go a long way toward cleaning up an ugly picture.

The fact that they suggest passing it through a VCR to use its "stablilization logic" suggests that the Apple II's composite video output is less than perfect for input to modern TVs. It is possible that the video circuit was designed around/optimized for the composite monitors they sold. I don't know enough to say, but I would not be surprised if what you say might be true about the filters is true. I think it might also be true that there is RF interference between your computer and the TV. Any chance you could describe what the problem is like or link to some pictures?
