George:

I agree that the 1070 will probably only switch DVI, for the very reasons I stated.

However, there IS a difference between DVI and component, but like many other things, it is dependent on the source. If the source is an ATSC bitstream or other decently "pure" digital signal that hasn't been DAC'd back to analog, the DVI should win out. Again, your mileage may vary based on considerations of original production material, quality of any conversions from digital to analog and back again, the use of any interim (so called "mezzanine" compression) during backhauls, the type of decoder used, and ultimately, the type of display used. (Is it a "pure digital" DLP, PDP, LCD or LCoS, or is it a CRT? That, too, makes a difference.)

Also, please don't take this the wrong way, but as a courtesy to others, is there any chance you could try to use capital letters so that your posts are easier to read? When they get long, it's hard to wade through them without the benefit of proper formatting.

But what do I know, I'm only a dog!
