Automatic screensaver is a nuisance

Your automatic screensaver is a hindrance. I need my tv to be on for 12 hours at a time, however the screensaver comes on automatically after 4 hours. I am at my witt's end about this. Why doesn't Cox allow subscribers to have the ootion of having their tv screen on all of the time? Surely I can't be the only Cox customer having this as an issue. I am on the verge of going back to Direct tv because of this problem. Please Cox give us the option of having control over our tv screen! If Cox provided this option, I would stay as a loyal, happy customer.
