This backlight will only fit on thin tv's so if you own one like I do that is about 4" thick the camera will not fit on it. I was told to send the unit back and buy another model that they have discontinued but which is available online aftermarket.
the Tv screen will be reflective. So it will refect the colour of the surroudnings more prominently during the day in sun light. It doesnt work well with larger TVs. we have an 80 inch tv and the calibration is always slightly off.
Ambient TV back lighting works better than I ever expected. As bright or as dim as you want. Glad I waited for 3rd generation to buy. I do wish the camera could be more securely fixed to the top of the TV rather than just balanced on top with a counterweight. Supplied two sided tape to help it stay in place is of little benefit.
