请问显示器的刷新率怎么調？

[Lucia]

我的显示器是NESO FD770A
但是安装了ubuntu之后分辨率1024＊768时刷新率只有60HZ，我进系统里面的屏幕分辨率调节刷新率也不行，它只能是60HZ，没有别的可选的项目，但是我的这个显示器在1024＊768下是可以上85HZ的，不知道怎么调，谢谢大家指点一下：）

我看过那个网页上的内容了，也照着做了一遍，可是刷新率还是60hz，还是没有可以选的别的频率，怎么办啊？ ：（

# 1024x768 @ 85.00 Hz (GTF) hsync: 68.60 kHz; pclk: 94.39 MHz
Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync +Vsync

复制并粘贴输出的内容到你的 Monitor section.

备份原/etc/X11/xorg.conf
执行 sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_orig

在终端下运行xorgconfig重建xorg.conf文件！

我按照你说的做了一遍，现在在800＊600的分辨率下显示器的刷新率可以达到56HZ，60HZ，72HZ，但是1024＊768和640＊480下显示器的刷新率还是只有60HZ，请问是为什么我1024＊768刷不上85HZ阿？我的显卡是NVIDIA Geforce Ti4200，显示器是NESO FD770A，我该怎么做才能刷上85HZ呢？

You must indicate the horizontal sync range of your monitor. You can either
select one of the predefined ranges below that correspond to industry-
standard monitor types, or give a specific range.

It is VERY IMPORTANT that you do not specify a monitor type with a horizontal
sync range that is beyond the capabilities of your monitor. If in doubt,
choose a conservative setting.

hsync in kHz; monitor type with characteristic modes
1 31.5; Standard VGA, 640x480 @ 60 Hz
2 31.5 - 35.1; Super VGA, 800x600 @ 56 Hz
3 31.5, 35.5; 8514 Compatible, 1024x768 @ 87 Hz interlaced (no 800x600)
4 31.5, 35.15, 35.5; Super VGA, 1024x768 @ 87 Hz interlaced, 800x600 @ 56 Hz
5 31.5 - 37.9; Extended Super VGA, 800x600 @ 60 Hz, 640x480 @ 72 Hz
6 31.5 - 48.5; Non-Interlaced SVGA, 1024x768 @ 60 Hz, 800x600 @ 72 Hz
7 31.5 - 57.0; High Frequency SVGA, 1024x768 @ 70 Hz
8 31.5 - 64.3; Monitor that can do 1280x1024 @ 60 Hz
9 31.5 - 79.0; Monitor that can do 1280x1024 @ 74 Hz
10 31.5 - 82.0; Monitor that can do 1280x1024 @ 76 Hz
11 Enter your own horizontal sync range

Enter your choice (1-11):
此时输入7后按回车进入下一步（注意此处应根据你的显示器的性能设定，最高刷新率是根据不同的显示器而不同的，我一般建议输入７）！

你试试在这一步输入7或者10试试!! 可能你的不支持87HZ 所以没法上吖!

　 型号 FD770A
　　水平扫描频率 　30-72KHz
　　垂直扫描频率 　50-130Hz

请楼主把xorg.conf传来看下？

我试过选7了，但是在1024＊768的情况下还是只有60hz，这个是我的xorg.conf

将以下部分
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 28-49
VertRefresh 43-72
EndSection
改为
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 0-0
VertRefresh 0-0
EndSection
试试！

[Lucia]

我弄好了，现在可以上85HZ了，我把xorg.conf里面的

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 28-49
VertRefresh 43-72
EndSection

改成了

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 30-101
VertRefresh 60-160
EndSection

然后重启再进屏幕分辨率就可以调了

[yonsan]

我的是可以的！

[Lucia]

谢谢大家的指点！

[firehare]

应该是只要改分辨率就可以的呀！

[xiaosir]

应该是只要改分辨率就可以的呀！

这可不认同，分辨率和刷新率是根据水平和垂直扫描频率来决定的，楼主xorg.conf是由于V，H扫描频率设置过低，自然达不到所需要的分辨率和刷新率。
