The Samsung UN40C7000’s rich display of 2D content makes me forgive its occasional hot spot hiccups that are still too prevalent in edge-lit LED displays. And its 3D performance is not the in-your-face experience that you might desire. […]
If you want a great display stay away from LCD TVs that sport edge-lit LED backlights, instead look for full LED backlights and local dimming technology. They cost more but the TV-watching experience will be more enjoyable. Also, thin is over-rated, unless you plan to mount the TV on the wall. The UN40C7000 is going for US$1399.98 at Amazon, but consider a Panasonic plasma instead if you’re watching TV in dark rooms.
