iPad HDMI out not showing in Atem TV Studio

We have an ATEM Television Studio and an iPad 4th generation.

When we configure the mixer to 720 59.94p we can see the iPad correctly but when we configure the mixer to 720 50p we can't

any suggestion ?

When you changed your ATEM to 720p50 did you change your ipad as well?

I think there isn't a settings for HDMI out on the iPad 4th generation/ iOS 6.1

this is why I've been asking for the hdmi on the atems to only advertise the current settings

Use an EDID fixer that might do the trick.

what is an EDID fixer ? A piece of hardware ? I couldn't find one in google

Like this but there are others

what it does is replace the EDID info so that your device will output only the resolution you want it to.
