Video flickering when recording a screen with a mobile phone When recording a computer screen straight with a mobile phone, there are sometimes colored spots to see in the recorded material. I know that when recording CRT displays, the flickering was caused by different refresh rates between recording device and playing device. Can I prevent the flickering/discoloration in spots on a mobile phone?
This should be a comment I guess but I don't have enough rep.

What kind of monitor are you using?

My iPhone records my 27" Retina 5k monitor just fine.

My guess is you have an LCD monitor and you are having polarizing issues (
