The TV so far, no complaints. 46" to 55" is a big difference.
However, I did come across a landmine of sorts.
My old Harmon Cardin AVR355 audio receiver won't handle 3D signals. Something about HDMI 1.4 being required for 3D signals to pass through from the 3D blu-ray to the TV. My receiver only accepts HDMI 1.3 signals.
The end results, last night when I got everything set up and popped a 3D video into the 3D capable blu-ray, I get a message on the TV screen stating that there is an issue and it won't play my video.
After much online digging, I found out about the whole HDMI 1.3 v.s. 1.4 standards, and the grief that has caused a few people...and here I thought I had figured it all out.
Looks like I may be in the market for a 3D capable audio receiver in the very near future.
