Here is a review:
The main difference between this LG and the step-up LM7600 series is refresh rate: 120Hz on the 6700 and 240Hz on the 7600 (the latter also gets a dual-core processor). According to LG, the LM6700 uses a 60Hz panel with a scanning backlight for what the company calls "Black Dimension Insertion" and claims is a 120Hz effect. The LM7600 has a 120Hz panel, which combined with a scanning backlight equals, per LG, 240Hz.
Unlike other 120Hz sets like last year's LW5600, the LM6700 does not offer smoothing (dejudder) processing. I didn't miss it, but some viewers might. The LM7600 does have a smoothing option and requisite TruMotion control that adjusts the effect. Based on those specs differences, I don't think the LM7600 would be worth the extra money (about $250 right now).
The LG literature states:
Refresh rate(s). 120Hz. Dejudder (smooth) processing. No.
The box it came in states: 120 Hz, in big bold letters on the side.
Now, I understand that the panel rate is 60Hz, but the effective rate is 120 Hz.
So, I stand corrected. Frankly, It strikes me as a bit dishonest on the part of LG, but I'm beginning to understand their MO. I'll never buy another LG product, that's for sure. Snarky advertizing claims don't sit well with me.
