LG Electronics is making an 84-inch flat-screen TV that'll sell for $22,100 in the U.S. The only problem, since it shows 8 million pixels per frame, which is four times the quality of current high-definition broadcasts, it's not compatible with most broadcasts in the U.S.The BBC offered some of their Olympics coverage in that resolution, but that ship has sailed. Still, Havis Kwon, the president of LG's entertainment diversion, said there is demand for the new mega-big-screen. "We have a clear target audience, it's about the access and how to market them," he said.
