1. That's the incoming signal. The television will always upconvert the signal to 1080p and 120Hz, but that process is done internally.
2. I'm not familiar with that box. Is it an on-screen menu perhaps for a cable/sat box or other attached device?
Samsung LED TV
I have two questions on the information on screen after pressing the "INFO" button on the remote:
1. The TV is 120Hz, why does it say 60Hz on screen?
2. A box sometimes pops up in the lower right corner that displays a meter with LED on the left and conventional TV on the right. What is this box? I could not find anything in the manual.
