While I’m debating with myself whether I should go for a 1080 TV or settle for a 720 one, Sharp have introduced an amazing 64 ” monitor that’s 4000×2000 pixels. That’s right, it’s effectively an 8 megapixel monitor. Four times the resolution of a 1080 TV.

That’s still about 25 million pixels shy of the UHDV format (7,680 × 4,320 pixels) pioneered by JBC.
It took quite a while for cameras to catch up with regular HD, Sony recently upped their FX1 cam to “full HD 1080″ with the new Sony FX7.
Interesting,however resolution is not so important you should look at the dpi(ppi)
