See my last line above:

Sony's XBR-84X900 TV has 3840 pixels across - advertising that as 4K is false advertising.
Companies calling 3840 pixel wide products 4K, or even worse, calling 7680 wide products 8K risk a lawsuit (like according to hometheaterreview, they did by calling screens a certain size when they were really under that) and even if they didn't , it's still misleading consumers.
I think another problem with the "Ultra High Definition" name (or even 4K name) for TVs is it doesn't specify the supported frame rates. When broadcasts start using UHDTV1, it's very unlikely they'll be limited to the frame rates that these current TVs are with the current HDMI standard (eg. max of only 30Hz at 3840x2160) - it's likely they will use at least 50/60Hz for UHDTV1 broadcasts.Edited by Joe Bloggs - 10/20/12 at 10:12pm
