I have been trying to adjust the focus on my Samsung DLP. I took the back panel off and have been manuly adjusting the focus using the focus ring adjustment technique. When I bring up the internal cross hatch pattern in the serive menu I find the lines to be jagged or saw tooth like. My question is do I want the jagged or saw tooth lines or should the line be smooth? I know when adjusting the sp actuator you do not want the lines to be saw toothed. Thanks in advance.
