Thanks Quinnicus. I spent a great deal of time during the game experimenting with these settings with no real success. The effect seemed to disappear when the tv picture mode was set to standard though.
My assumption is that this must be something to do with the device I'm streaming it from. My PS4 is connected to the tv via an HDMI cable. I will have to experiment with some live football that does not come via the PS4 to be certain though. Are you able to suggest any fixes or avenues for investigation if this is the cause?
