Perhaps the biggest addition to G450 was that Matrox moved the previously external second RAMDAC, for the second monitor connector (DualHead), into the G450 chip itself. RAMDAC speeds were still different though, with the primary running at an excellent 360 MHz, but the secondary running at only 230 MHz. This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. This was the same as G400. The G450 also had native support for TMDS signaling, and thus DVI, but this was not a standard issue connector. Boards shipped with dual analog VGA connectors.
