Hello, as said above what the hell is it for? The brand of my tv is alba, the model number is LCD32880hdf It ONLY appears when I connect my games consoles via HDMI, and it appears to let me see more of the image, it doesn't seem to effect the image itself just it's aspect ratio. I've had it on for now. I havnt tried though to see if the option would appear if I connected a HDMI DVD player to my tv. Should I have it on? Thanks in advance.
