My 46 HX750 arrived this morning along with the Sony HT-CT150 (sound bar). I set it up earlier this evening and will share some of my first impressions...
First off, I'm no videophile, but I think the picture quality is incredible. A huge improvement compared to the 1080i Sony WEGA DLP that I've been using. I did notice some flash lighting in the bottom corners and in the upper left corner; however, it's very minor and I only noticed on a pure black loading screen (can't notice it during regular usage).
I'm a big gamer, so I threw in Call of Duty: Modern Warfare 3 for a couple rounds to test the television. I have to say that the saturated colors, bright backlight and sharp 1080p screen made the game feel like an almost entirely new experience. The first round reminded me of those cliche scenes in movies where someone is putting on their glasses and the screen shifts from blurry to clear. Remarkable. I'll also note that I played on the televisions standard settings... I looked for a 'game' setting, but could not find it in the menus. Does the HX750 offer such a mode? If so, where can I find it? Regardless, I did not notice any sort of input lag while playing.
Finally, the sound bar. One of the main reasons I bought it was because it offers 'Bravia Sync', where it works to unify home theater devices so that you only need one remote. Well I hooked my inputs up to the sound bar receiver/subwoofer and then connected the receiver to the television. The television automatically finds the external audio, so I'm able to control the volume with my television remote; however, I can't change the receiver inputs with my television remote. It's not a deal breaker by any means, but if it is feature that I'm able to take advantage of, then I want to be able to do it. For those of you familiar with Bravia Sync, do you understand what I'm asking? Is it possible to do what I'm trying to do? Anyway, I was very impressed with the sound bar in terms of audio quality. It produces surprisingly crisp audio with a deep bass for its small size.
All-in-all I'm very happy with both products and can not wait to spend more time with them.
