While strolling around Shenzhen earlier today, we decided to stop by at the China Optoelectronics Display Expo to feast our eyes on AUO's "world's largest" 71-inch 21:9 3D LCD panel. Phew, what a mouthful, but this 240Hz ultrawidescreen is indeed larger than the sub-60-inch offerings from Vizio, JVC, and Philips. But is it any good? We put on our passive 3D glasses and found the experience to be surprisingly comfortable and effective (even at about 40 degrees from the center before we hit the wall), though the glossy screen's reflection of the neighboring booth was slightly off-putting. This would probably be less of a problem at your humble abode, anyhow.
