I've had my 47LG70 for three days and I'm really loving this TV! My last TV was a JVC 56FC97. The LG is better than the JVC in every way. The picture is bright and sharp. Even with the 120Hz turned off, I found it to have less blur than the JVC. The anti-glare screen is amazing. One of the main reasons I got a LG was because of this. I have multiple windows in my living room, and even if I position the TV so that it is directly facing a window, glare is not an issue. I can see glare from the shiny frame around the screen, but nothing from the screen itself. I also really like the swivel stand. I was going to buy a wall mount just so I would be able to swivel the TV. This stand saved me from having to do that. I have to mention that when I first turned on the TV, I was not crazy about the PQ. It took a bit of tuning before I was happy with it.
When I was looking at this set at the store, I was not able to see the difference between the TruMotion on vs off demo. Now that I've had more time with it, I can definitely see a difference. This feature is most noticeable when the background changes quickly, like when the camera pans. It gives a strange smoothness to the picture that doesn't seem right at first. Perhaps it's because I'm use to seeing some blur in these situations. I got use to it after awhile. TruMotion can be set to High, low, or off. On the high setting, I have seen it cause the picture to get pixely / noisy around the fast moving object. Low setting reduces this effect a lot, but it can still occur sometimes. The good news is you can turn it completely off if it really bother you. I have it set to low and in my opinion, it does more good than bad.
I don't think I saw any Triple ball effect. When watching tennis, there was a slight blur to the ball, but I'm pretty sure that it's from the source, and not the set. It was very minor and didn't bother me at all.
The Intelligent sensor is a nice thing to have. I was able to test this out by shining a flash light on the sensor. It's kind of cool seeing the settings change on their own on the on-screen menu. The only beef I have with this feature is it changes more than just the Backlight brightness. It changes other settings like Sharpness and Color. Also, with the intelligent sensor on, you won't be able to adjust the sharpness or color settings. At first I didn't care for this feature, but it got better after a bit of tweaking and started to grow on me.
Overall, I'm very happy with this TV. The only thing that could have been better is if TruMotion worked without any hiccups. But even so, I still highly recommend this TV.
