Unfortunately, the other specifications for the display aren't nearly as interesting as the resolution. The brightness is only 235 cd/m2; most high-end displays feature brightness in excess of 300 nits. The contrast ratio is 300:1 and the display can produce 16.7 million colors. Viewing angles are simply abysmal at 120 degrees horizontal and 100 degrees vertical.
Toshiba advertises that it will sell the display for 2,079,000 yen, or approximately $18,000 USD. Toshiba also lists a required video card at a price of 312,000 yen or about $2,700 USD, though most high-end video cards today should have no problem supporting ultra-dense resolution -- but don't expect a casual game of Crysis at that resolution.

Don't even think about gaming on this. Specs are horrible, and price is just ridiculous.
