sorry, the image is being scaled to fit 1366x768, it displays 1080, but at 768!!i had the option of running 1366x768 on my CCC with my 4870, but with my 5770 i dont have that option. The resolution is definitely different!
TV firmware just makes 1080i, 'fit' to a 1366x768,
And from that i get a massive performance boost?
