In what seems like a blizzard of interesting product announcements, LG Display—the company that manufactures the glass for LG's and other companies' LCD TVs—has announced it will unveil several hot items at CES. First among them is an LCD panel with a refresh rate of 480Hz, four times that of 120Hz panels. What's the point, you ask? Isn't that just meaningless marketing numerology? Perhaps, but perhaps not. I intend to find out for myself, so stay tuned.
