There is no 1020p resolution unless that is a typo. No major cable provider offers 1080p broadcasts yet. All HDTV broadcasts are either 1080i or 720p. Most stations, such as CBS, NBC, and others, are 1080i. Fox, ABC, ESPN, and their various siblings are 720p. Your cable/satellite box can be set to output a specific resolution. As indicated in the title description, the LG Full HD 1080p LED TV - 43" Class (42.5" Diag), Model # 43LJ500M has a native resolution of 1080p so when presented with video images, it will always play them in its native resolution. The signal showing on the screen is the incoming signal and the TV automatically adjusts to either upconvert that signal or downconvert to its native resolution. The scaler/deinterlacer in your TV is far better than what's in your cable/satellite box and not all cable/satellite boxes offer native resolution as an option. Also, there could be a delay in changing between 720p and 1080i channels as your TV adjusts to the new resolution. For advise on where to find the settings for your set-top box, please contact your cable provider's Support Center...^IFV
