@belardo, sharpness is relative to dpi not resolution, so it would only look grainy compared to the smaller tv's if you're at the same distance. If you're farther back it's gonna look sharper.
If the 30" panels are for tv's, then when we will see them for monitors? WQXGA resolutions combined with OLED technology would be so damn amazing, it's mindblowing just thinking about it. Well worth the thousands it'll cost 😛
