Wanted to share my broken XBR5 changing to HX929 results.
I got my new 55HX929, it is bigger vs. 46XBR5 I had.
Spend few weeks playing with settings. I was also trying famous Imrizzo settings.
Settled now on the best per my taste, the most close I can achieve to match to my XBR5 (still works after warm up, perfect for side by side comparison).
Well, the 55HX929 is not even close by brightness-crispiness, color appearance-deepness wise. I know in fact and understand that one TV set is not equal to another TV set. And it is nothing wrong with my unit, it performs close to others I seen in retailer stores on display.
Based on what I see on the screen, on all the black levels, leaking lights, shadows and etc, it makes me thinking that HX929 LCD panel by itself has lower contrast ratio vs. XBR5 panel (I mean not looking to those electronically artificially boosted blacks, I do not care about them). In other words, my particular HX929 unit has lower grade panel vs. XBR5, period.
I read that Sony has switched from Samsung panel to someone else. Well that most likely brings lower performance at lower cost. The LCD panel on HX929 is a step back. I am talking here about my particular unit and not all TV sets that others might have, performing differently and better than others, as you may read on dedicated to HX929 thread where many loves how it performs.
