Nigel blogged about the Tritton SEE2 USB-to-VGA a couple of years ago, but the Tritton people haven’t been standing around since then. They’ve just released the SEE2 Xtreme USB-to-DVI video adapter and they’ve added Mac OS X compatibility.
The Xtreme allows people to add multiple displays to their desktop or notebook even if their video card doesn’t support extra screens. The Xtreme provides resolutions of up to 1920 × 1200 in DVI or VGA with 16 bit colour. If you want 32 bit colour though, you’ll need to stay below 1600 × 1050 resolution. You can also watch videos over the Xtreme and it supports widescreen resolutions plus extended desktop and rotated displays. If you want to really go nuts you can add up to 6 screens to a PC (4 to a Mac), just be sure have a spare USB port and an Xtreme box for each monitor.
The SEE2 Xtreme is the easiest and most cost effective way to add multiple displays to your computer.Now supporting Mac OS X, the SEE2 Xtreme lets Mac users add an additional display through USB 2.0. Mac and PC users can achieve max resolutions up to 1920 x 1200 for DVI and VGA. Add up to four external video card’s via available USB 2.0 ports for Mac users. Add up to six external video card’s via available USB 2.0 ports for PC users.
