Thanks for telling me what I'm doing is incorrect without offering help. I am fully aware this is not how you should be hooking up the TV. However, I have been told by LG there is no way to get a full screen image for SD channels without using zoom.
I explained in my first post. Your cable box, if connected via HDMI and outputting HD, should have a menu option somewhere to output 480i content as stretched 16x9. You may have to turn the cable box off to get to that menu.
Not only are side bars annoying but they also cause image burn according to CNET.
Image burn-in hasn't really been a problem for at least 5 years now.
As I have no HD signals, that means ALL of my channels have sidebars.
So you have an SD cable box? I haven't seen an SD cable box with an hdmi output. Or do you have an HD cable box, but only pay for SD?
Guys what gives with all pointless posts on this forum? If a person posts that they want to do something with their TV, that is their preference. They are looking for help, not comments on how incorrect or silly what they are doing is. If you do not have a suggestion as to how to help fix the issue, then don't post at all.
If you read my first post to the OP, I helped all that I could with the information I was given, and I asked for more information to be able to help.
