Hello,

I have this video card (product: NV18 [GeForce4 MX 440 AGP 8x])
I want to use it on my ubuntu linux with this 1024x786, rfresh 75, 80
Please if anybody can tell me how can I do it!

I installed the driver from www.nvidia.com and I can choose only refresh 50 or 54MHz; and it is horrible. Please tell me how can I configure it to be able to choose refresh of 75 or 85.

thank u!

It is possible that whichever tool you're using to set the refresh rate (which tool are you using? nvidia-settings?) doesn't let you choose higher frequencies because the monitor definition of X says that they're out of the supported range of your monitor, and/or, that your monitor (a CRT, right?) does not deliver to the graphics card the EDID which tells which are its supported frequencies.
You could try to have a look at your xorg.conf file (in my Gentoo distribution is under /etc/X11/xorg.conf) and check the entries called "HorizSync" and "VertRefresh" and eventually "Modeline", all under the "Monitor" section and play around with them. You could as well post here the contents of the file.

In my case, e.g. just yesterday I connected a second LCD display to my GPU but it didn't want to display a res higher than 640x480. I therefore modified "HorizSync" and changed the top range value from 50 to 80 and now everything is alright.

But be careful: setting a too high frequency might damage your monitor.

p.s.: you could try as well to play around with "xvidtune".

sorry that I reply so late

i am using nvidia-settings v 1.0
but i don't understand how can I set up refresh rate with this tool?

i think this is my problem. i can't set up a higher refresh rate.

thank u

this is my xorg.conf

how can I put here refresh rate ?

Where you have...
...try to make it look like this...
Those ranges should tell your graphics card which refresh rates are supported by your monitor, and therefore which resolutions & refresh rates can be attained.
But be careful with those ranges - setting too high limits might harm your monitor.
