症状：技嘉GA-G31M-S2C的主板，是集成显卡，连接的是LG 1942SP的显示器，安装光盘里面提供的驱动也无法使用1440*900分辨率
更新过显卡驱动，重新安装过显示器的驱动都无法解决问题。
解决办法：
这个问题导致跟显示器是没有关系的，主要是显卡的驱动问题
Intle的官方已经修复了此问题，只需要下载最新的G31显卡驱动（win2k_xp_14365bb.zip）就可以了。
下面是Intel的官方修复介绍：
Symptom:
Users may be unable to use the native resolution of some displays when using Intel chipset graphics. Resolutions such as 1680x1050 and 1440x900 are not available in graphics properties.
Cause:
The display EDID is not read properly when connecting to a subset of Digital Flat Panel (DFP) displays.
Solution:
Intel has released this driver to specifically address this issue however, there may be side effects to this solution such as longer than normal resume times from standby. This solution will only work with external displays such as DFP displays. This driver is not designed to address issues with Local Flat Panel displays or TV's connected to the system. This driver is provided as is. Intel has not tested, and does not warranty, the operation of the driver for this purpose.
This file is written specifically for the Intel 946GZ, G31, G33, G35, G41, G43, G45, Q33, Q35, Q43, Q45, G965, Q963, and Q965 Express Chipsets and the Mobile Intel GM45, GL960, and GM965 Express Chipsets and will not function with any other product. View the README file for installation information and the RELEASE NOTES for driver version details. This driver package contains the version 14.36.5.5016 (Build 6.14.10.5016) drivers for Windows* XP.

症状：
用户可能无法使用某些显示器的原始分辨率时，使用英特尔芯片组的图形。例如1680x1050和1440x900的决议不具备的图形性能。
原因：
显示EDID是不正确读取时，连接到一个数字平板（DFP中）显示的子集。
解决方案：
英特尔已经发布了这个驱动，专门解决这一问题，但可能有副作用，这比正常的时间从待机状态恢复解决方案，例如更长的时间。该解决方案将只工作，如DFP中显示外部显示器。此驱动程序不被设计为解决本地平板显示器或电视机的连接到系统的问题。此驱动程序提供的原样。英特尔还没有测试，不保修，为此目的驾驶员操作。
这个文件是专门为英特尔 946GZ, G31, G33, G35, G41, G43, G45, Q33, Q35, Q43, Q45, G965, Q963, and Q965高速芯片组和移动式英特尔 GM45，GL960和GM965的高速芯片组的功能，不会与任何其它产品。查看安装信息和驱动程序版本的发行说明详细的README文件。此驱动程序包中包含的版本14.36.5.5016用于Windows * XP（建设6.14.10.5016）驱动程序。
