Easy to test
1) Display DNice slides over scan off , Full aspect.. It should fill every pixel
2) If #1) is true any other Source with overscan off with Full aspect that does not fill the screen is the source not the panel. Example my FiOS DVR is about "1070i"
BTW one of the reasons i chose DNice slides over HBO for first 100 hours (open Pandora's)
