Hi, I have a 1,5 year old Sony Bravia KDL-32P3550 and I'd like to know if there's any way to disable overscan so, that the pixels are 1:1. Does anyone know? I recently purchased a Blu-ray player and want to make sure I'm getting exactly the image that the disc offers. Some TVs offer the opportunity to display a 1:1 image through VGA, but my Blu-ray player doesn't have that connection possibility and I'd like to use HDMI anyway. Thanks for help!
