#1

帖子 Lucia » 2005-07-15 21:58

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:)

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? :cry:

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!
I will be back!

  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!

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

firehare 写了: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。
