In general using the internal blu-ray drive in your computer would probably give you the best results (as long as you're using displayport). The reason for this is is that movies are generally recorded in 24 fps. Displayport allows you to use 120Hz on the S27A750D/S23A750D, and 120 is exactly five times 24. With HDMI you're only going to get 60Hz, and 60 is neither 2 nor 3 times 24. Therefore, at 120Hz your monitor might simply show the same frame 5 times, while at 60Hz your monitor might show some frames 2 times and other frames 3 times or something like that (depending on how the S27A750D/S23A750D will handle these situations).
Of course, other factors like the software you're using to play movies, the quality of your bluray player etc might also make a large difference that might impact you're image quality even more greatly.
Anyway, 120Hz is generally
smoother compared to 60Hz for movies because it is exactly 5 times 24, and you can only get the 120Hz with this monitor when using displayport. Therefore, the way to go would generally be to use the internal blu-ray drive of your PC (with displayport) instead of a blu-ray player with HDMI.
