G31竟然调不到宽屏分辨率

下载驱动程序，然后不要安装，用WINRAR打开并解压缩到一个文件夹，然后在Graphics文件夹中找到inf文件,在这里是igxp32.inf
打开文件,找到:
[NonEDIDMode_AddSwSettings]
HKR,, TotalDTDCount, %REG_DWORD%, 0 This shows number of DTDs to be used. ;0-->Disable the feature.
;Following keys have 20 bytes (18 byte DTD + 2 Byte flags).
HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01 ;1920x1080@60...Interlaced
HKR,, DTD_2, %REG_BINARY%, 01,1D,80,D0,72,1C,16,20,10,2C,1A,80,00,00,00,00,00,86,37, 01 ;1920x1080@50...Interlaced
HKR,, DTD_3,%REG_BINARY%, 01,1D,00,BC,52,D0,1E,20,B8,28,25,40,00,00,00,00,00,04,37, 01 ;1280x720@50....Non-interlaced
HKR,, DTD_4, %REG_BINARY%, 01,1D,00,72,51,D0,1E,20,6E,28,25,00,00,00,00,00,00,06,37,01 ;1280x720@60....Non-interlaced
HKR,, DTD_5,%REG_BINARY%, 00, 00, 00 ,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00, 00,00, 00 ;Fifth DTD

其中
HKR,, TotalDTDCount, %REG_DWORD%, 0
改成
HKR,, TotalDTDCount, %REG_DWORD%, 1
1代表你要加入1个自定义显示模式 ;后面分号是注释

再把
HKR,, DTD_1,%REG_BINARY%, 01,1D,80,18,71,1C,16,20,58,2C,1A,00,00,00,00,00,00,86,37,01 ;1920x1080@60...Interlaced
改成
HKR,, DTD_1, %REG_BINARY%, B9,22,A0,A0,50,84,1A,30,30,20,36,00,00,00,00,00,00,1A,37,01 ;1440x900@60....Non-nterlaced
保存退出,运行上级文件夹中的setup程序,重启.打开显示 属性-高级-监示器,取消"隐藏该监示器无法显示的模式"-应用-适配器-列出所有模式,找到1440*900.

是VGA线的问题。我遇到过，更换线后就正常了。
