Q: What resolutions or formats are compatible with the 9A60?
A: The 9A60 is compatible with all 18 ATSC formats including 480p, 720p, and 1080i. Remember that your HDTV set
must be compatible with the format of your source unit. For example, a 1080i RGBHV source with a 9A60 will require
your HDTV monitor to accept a 1080i Y Pb Pr component video input.
