Just introduced a 1080i input to my 2300. When I use a 480p signal there is no problem, but at 1080i or 720p, I get a small dash line above a 16.9 image. If I have a 4.3 input a flickering line is above the the whole image. Reading on other threads that this is an overscan issue and overscan can be adjusted on the projector. How do I adjust the overscan on my Dell 2300mp?
Thanks.
