Pull your talent as far away from the screen or to the side as possible.. Light him separate. This is to typical. Most HD tvs you may want to change the setting and bring the brightness down a bit. Gonna take some time to set it up and get it right. Make sure the presenter know not to walk in front of the screen and stay put. If he does move around bring him to the audience and forward .. Use a manual iris or each time you hit that sceen it
gonna go dark on you.. Never shoot with the light behind stronger the key light up front.
