Purchased this at CostCo. I wasn't expecting great things because of the relatively low price but the picture quality is amazing, better than the other 3 LCDs in our home. The HD picture is so clear that it took getting use to because the images seemed so real. It has an ambient light sensor which dims the screen light in dark and brightens it in daylight. I found it gets too dark at night for my liking. To disable the ambient sensor follow this sequence on the remote (Menu - Picture - More - Advanced Picture - Ambinet Light Sensor - off). Good luck.

I've owned this television for about a month now, and after you set it up and customize it to your viewing preference (it has a lot of options to tinker with) it's quite amazing. The picture is brilliant, vivid, sharp, and blacks are nice and dark. The smooth motion effect takes some getting used to because at times it may make a movie or show look like it's in fast forward when the camera is panning- I suggest keeping it on the "Medium" setting to counter this. The speakers are excellent, clear and loud. Vizio has really stepped it up with this t.v.

Recently purchased at Sam's Club for $748. TV was easy to set up and has lots of custom adjustments. Image quality is excellent, built in Sound is OK. Has a built in ambient Light sensor that dims brightness of screen automatically depending on room lighting, but I prefer an always bright screen, so turned the Light Sensor off. Very happy with this purchase, and if you are looking for a 47 inch flat screen LCD you have to take a look at this unit, its a great value !
