HD channels incorrect aspect ratio - too large for screen
Cable box is connected via hdmi to new LG tv. When watching HD channels the ratio is incorrect. The picture is to large for the tv screen. I can not find how to correct this.
Example - watching news in the morning. You can not see all of the information because it off the screen. The TV is in 16:9 mode. I can not find the cable box video settings.
Cable box only says Xfinity - model PR150BNM
