I just installed a new Slackware on my desk with KDE, by default it just has a 1024*768 resolution, so I installed the packages nvidia-kernel and nvidia-drivers with sbopkg. I rebooted and then I just typed nvidia-xconfig for make a new xorg.conf, after that, I saw there is not the resolution that I want (1600*900), so I added it in the configuration file (xorg.conf)
bash-4.3# xrandr
Screen 0: minimum 8 x 8, current 1024 x 768, maximum 16384 x 16384
DVI-I-0 disconnected (normal left inverted right x axis y axis)

640x480 59.94
512x384 60.00

320x240 60.05
DVI-I-1 disconnected (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
bash-4.3#
What can I do? Sorry for my english! I will be here is you need more information.

It should be reporting an EDID value (which I don't see)..
The other thing I see is that only the VGA connection is being used.
Now if the monitor is not presenting the EDID value (or for some reason it is incorrect) then it is possible that what is happening is that default values for the clock rates are being used (and may be incorrect).
I "worked around" this problem once by specifying the clocks for a monitor in the "section Monitor" using:
I once had a laptop with an nVidia GPU that had an incorrect value in the EDID.
I captured the EDID and used a hex editor to change the incorrect value. I then used the "CustomEDID" option provided by the nVidia driver to load the modified EDID. For further details see here

With this configuration I could set a higher resolution, but isn't the correct proportion.

Thanks for your reply! I tried to capture the EDID value with nvidia-settings, but the "acquire EDID" button appears like unavailable. (See the link)
Because of that, I installed the read-edid package from SBO. Here are the results:
Code:
# get-edid | parse-edid
This is read-edid version 3.0.2. Prepare for some fun.

Looks like no busses have an EDID. Sorry!

Try using 150 for the HorizSync. You can go higher, I just don't know what NVIDIA actually uses. For LCD monitors it won't hurt anything.
Thanks for your reply! I tried with that HorizSync and I still can't set the correct resolution.

What are the details of the monitor (manufacturer and model)?
Are you sure that it can operate with your preferred resolution?
If so, then I agree with jpollard that a custom ModeLine entry in the Monitor section of your xorg.conf is worth trying. In addition to the on-line tool, you can use 'cvt' to generate modelines.
You may also want to consider
Quote:
Option "UseEdidFreqs" "boolean"
This option controls whether the NVIDIA X driver will use the HorizSync and VertRefresh ranges given in a display device's EDID, if any. When UseEdidFreqs is set to True, EDID-provided range information will override the HorizSync and VertRefresh ranges specified in the Monitor section. If a display device does not provide an EDID, or the EDID does not specify an hsync or vrefresh range, then the X server will default to the HorizSync and VertRefresh ranges specified in the Monitor section of your X config file. These frequency ranges are used when validating modes for your display device.
Default: True (EDID frequencies will be used)
Option "UseEDID" "boolean"
By default, the NVIDIA X driver makes use of a display device's EDID, when available, during construction of its mode pool. The EDID is used as a source for possible modes, for valid frequency ranges, and for collecting data on the physical dimensions of the display device for computing the DPI (see Appendix Y, Dots Per Inch). However, if you wish to disable the driver's use of the EDID, you can set this option to False:
Option "UseEDID" "FALSE"
Note that, rather than globally disable all uses of the EDID, you can individually disable each particular use of the EDID; e.g.,
