Kuroutoshikou, sister company of Buffalo, will offer a couple of new USB graphics cards:
-VGA-USB/DVI (DVI out)
-VGA-USB/RGB (D-Sub out)

Both can display 1440×900 in WXGA+ or 1280×1024 in SXGA, need a USB 2.0 port to work properly, and at least a 1.2GHz Pentium III with 512MB RAM. Those can be combined, and if you plan on using 6 of them, you’ll need a 1.6GHz Core Duo and 1GB RAM, but don’t forget 6 screens!

Despite the compatibility with XP/VISTA, these new cards do not support the VISTA Aero theme with all the 3D effects… and will cost you from 8,980 Yen (60€) to 11,800 Yen (80€), available late December in Japan.
