Whenever the audio automatically changes (due to the cable company & how the audio is transmitted), The display keeps popping up showing the switch from 'Audio: MONO' & Audio: ST(SAP)' & 'Audio: STEREO'. Listening to the television, I can't hear the difference but the signal keeps popping up that it's fluctuating. I keep pressing Display & it won't go off. This doesn't come up with any of our other televisions - and it's annoying that it's occurring with this one.
