To be honest i find it very strange most people here agree it's on the monitor/recorder side.
I do a lot live projection with screens and beamers. Pre-made footage has practically 0 latency while my G85's have at lowest around 200ms latency.
resolution or output format on the camera side don't change this, other hardware on the output side don't change this.
Even at 720p30 it's always there. It's a shame.
highend got a reaction from Geoff CB in GH5 - major lag via HDMI out to ext. recorders?
