Hmmm.  Can you though?  Is it actually displaying true 1080p as claimed?  One test is to display an image with alternating coloured 
parallel adjacent lines that are each a pixel wide and see if they are detailed, as well as if they are all detailed.   Test 
patterns are also available on the Internet.  There should be 1080 horizontal lines seen (and debatably 1920 vertical lines) for 
1080p display.
