Oh you are talking about rolling bars due to a sync mismatch between camera shutter and monitor refresh rate.
That has nothing to do with advanced technology or not. It is a time aliasing artifact.
You have to set the camera shutter to the same frequency like the monitor your are filming.
For example if you are in PAL land with 50 Hz then you have to set your shutter to 1/50.
For NTSC TVs or most computer screens they are running on 60 Hz, therefor you need a shutter of 1/60.
Sometimes this does not work because screens might be set to an awkward refresh rate. Then you have to tap the shutter settings for the on-screen menu. There double tap the shutter value on the left side inside the < >
This opens an overlay where you can type in any exact shutter fraction you want. Like 1/59.788 or any degrees if you have set the camera to display shutter in degrees.
It is a bit of try and error to get the closest fitting value then.
