选购一款适合自己的显卡系列之3：HDTV, Big Displays, and Dual Monitors

本文讨论了新的显示技术如何增加了对图形芯片的需求，特别是针对宽屏显示器和高清晰度电视。文中详细介绍了不同分辨率下图形处理的要求，包括全高清视频播放的需求，并提到了双链路DVI接口对于更高分辨率的支持，以及在多显示器配置方面需要注意的问题。

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.

The Asus M2A-VM motherboard has both DVI and VGA outputs; a version with an HDMI port is available, as 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.
