What HDMI Version is my Pioneer Pro 1110HD?  

Hdmi 1.0. There is a VERY big difference in PQ when comparing to a 1130.

IMO, the biggest differences are deeper blacks and a lighter, less reflective panel due to the first surface color filter.

Yours might be one of the best, but a lot of people consider the 1130 to be THE best on the market today. However, I believe the FHD1 now holds that title ;)

The differences in PQ between your 1110HD and the newer Pioneers would not be noticed by 99% of the normal viewers sitting down to watch a movie or ball game. Yes the blacks are blacker, so that you might see slightly more detail in the darker scenes in a dimly lit room, but the differences are small. The 1110 is still a great TV and you would need to go to a 60+ inch 1080p to realize enough improvement for most people to notice.

There are distinct differences between the 1110 and the 1130. They are very obvious if you were to place them side to side. There is a distinct green haze on the 1110 that is not on the 1130. The colors on the 1130 are far more accurate compared to the 1130.

I bet if the OP were to visit a local dealer that has the 1130 on display, he would immediately see what the differences are.

How are those settings working out for you? ;)

I'll have to take your word for it as I don't know anyone who watches movies or ball games with two TVs side by side. Mine are in separate rooms so that the differences are not a big deal.
