The question is in regard to using a toaster while maintaining ZZ9000 output. The toaster changes the rgb output in some way creating composite sync at the rgb port. This output is then run through a ‘dongle’ sync strainer so it can be seen on a multisync crt monitor.
The ZZ9000 is (obviously) connected via hdmi to my flatscreen. In normal use I can see images on both monitors as long as I keep the NTSC monitor type in devs and use an NTSC mode (best as hirez laced). If I want any ZZ modes I can’t use the Toaster to my understanding so these modes are reserved for other computing sessions and they do work . The ZZ then does what it does and provides a nice display to the flatscreen. However, once the toaster is started and it Genlocks to the Amiga rgb output the ZZ looses sync in some way creating offset 4 box partial images over its hdmi output.
I’m trying to determine if this might be a flatscreen monitor issue where mine cannot display the output the ZZ is providing or if the ZZ is losing sync due to the composite sync/genlock condition.
And if so can some sort of driver fix this allowing the ZZ to work with composite sync?
Or some setting I could make allowing for this mode.
I have seen others using a Picasso IV card in this manner unfortunately I have no setup data to draw from.
