It's possible that there is an issue with EDID detection but I thought that was the whole
purpose of forcing a resolution and refresh rate....
I have tried with the other HDMI port but it behaves the same way and I tried with another HDMI adapter with the same result.
I do believe there is a bug with the Rpi4 version but it's odd that this is where it would manifest
itself.
I really like recalbox so I I'll investigate some more and I am willing to wait for the bug to be fixed. I'm use to using open source projects so I've developed a healthy amount of patience
so I'm good.
thanks for your help!
