http://www.xlr8yourmac.com/Graphics/Samsung_240T_info.html "The TMDS signalling in the DVI interface has a maximum bandwidth of 165 Mhz, or 165 Mpixels/s. At 60 Hz this equals to a maximum resolution of 1920 x 1080 for the display over single TMDS link. Obviously not enough for a 1920 x 1200 display. However the standard DVI interface has enough pins for two TMDS links and there are both displays and cards with a single or dual TMDS implemented (12 or 24 pins). A dual link DVI interface has double the bandwidth and therefore a maximum resolution of 2048 x 1536." Maybe? More interesting info in the article. -Jack
