Just wait until the prices of the LG World Record 4K TVs come down. Then that would be end of the 540p argument! Before that happens, personally, sitting a reasonable distance from the TV, I don't really notice a decrease in the picture quality when watching passive 3D. I do notice the interlaced lines when I am up close to the TV, however. The experience is different for everyone, so I recommend everyone to check it out for him or herself before making a judgment call on that.
LG WRman Sherlock, out!
