A520 HD works with some displays not others

Hi, I have an A520HD that I'm using with an Amiga 500. When I have it connected to an older Mitsubishi Projection TV it works fine but when I connect it to newer devices the displays never detect the signal.

I'm using an NTSC Amiga and every display and receiver that I've tried supports 60Hz as a refresh rate. I've tried an RCA TV, a Yamaha receiver, and a component to HDMI converter, all with no luck. Do you have any suggestions on what I can do to make it work with the newer devices?

Thank you!


Unfortunately, the sync output of the Amiga is slightly non-standard. The vast majority of older TVs have no problem with the small differences. Some of the more modern TVs have a digital sync detector that follows strictly the standard and fails on the Amiga output.
