You will need to use a 120Hz controller board!

what you may want to look for is a ALR1920-120 from digitalview. But be warned: These boards are expensive!

I've assigned 128MB and later 208MB to the GPU. Zero W is not booting at all, a Raspberry 3 runs fine with that uSD. Second framebuffer is not enabled yet (max_framebuffers=1), DPI is not enabled too, so only one display connected to HDMI. That's why I would guess it's something different, not memor...

o.K. tested with a zero and see the same problem here.
