I had the 2405 for a long time now but never attempted to connect it to my sony dvd changer. Last night I decided to try this out to see how the picture compares to watching a dvd in Windows using WinDVD. The 2405 is currently connected to my PC using the DVI-D connection running an Ati x850 AIW. Overall the picture was good. I then connected it to my dvd changer using component cables and set it for 16:9 progressive scanning. I was pretty blown away at the difference in picture quality. Much better details and color reproduction. I can only imagine how much better it would be even more if my dvd player can upconvert to 1080i.
