Newer display technologies, such as wide-screen monitors and high-definition television (HDTV), now put extra demand on graphics chips, too. For example, most of today's integrated graphics solutions can display full-screen high-definition video smoothly
at HDTV's lower resolution (720p), but only the fastest chips handle 1080i HDTV playback well.
Another issue to consider is maximum resolution. A graphics chip must support "dual-link" DVI for it to output at resolutions higher than about 1,920x1,080. If you've been eyeing a big 30-inch monitor that supports 2,560x1,600 resolution, you'll need a dual-link-capable
card.
Finally, dual-display configurations are worth considering. Most motherboards equipped with integrated graphics have only had a single VGA display output. Some newer boards have both VGA and DVI ports, and the latest boards can even support dual digital
displays via DVI and High-Definition Multimedia Interface (HDMI). If you plan to use more than one monitor, be sure the motherboard or system you're considering features an appropriate pair of ports for the displays you have on hand.
