Default xorg.conf screen resolution

I am running kde 3.2.
Right now I am trying to get it recognize my monitor can handle resolutions
above 1024x768. I have eliminated all the other options in my xorg.conf file
Here it is btw:


# ************************************************** ********************
# Screen sections
# ************************************************** ********************

# Any number of screen sections may be present. Each describes
# the configuration of a single screen. A single specific screen section
# may be specified from the X server command line with the "-screen"
# option.
Section "Screen"
Identifier "Screen 1"
Device "videocard0"
Monitor "My Monitor"

# If your card can handle it, a higher default color depth (like 24 or 32)
# is highly recommended.

# DefaultDepth 8
# DefaultDepth 16
DefaultDepth 24
# DefaultDepth 32

# "1024x768" is also a conservative usable default resolution. If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)

Subsection "Display"
Depth 8
Modes
EndSubsection
Subsection "Display"
Depth 16
Modes
EndSubsection
Subsection "Display"
Depth 24
Modes "1280x1024"
EndSubsection
Subsection "Display"
Depth 32
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
EndSubsection

EndSection

32 bit depth also isn't working?
Why is it still defaulting to 1024x768 you think?

Here is the video card section:
# ************************************************** ********************
# Graphics device section
# ************************************************** ********************

# Any number of graphics device sections may be present

Section "Device"
Identifier "videocard0"
Driver "nvidia"
#VideoRam 4096
# Insert Clocks lines here if appropriate
EndSection
Here is the monitor section:
# Any number of monitor sections may be present

Section "Monitor"

Identifier "My Monitor"

# HorizSync is in kHz unless units are specified.
# HorizSync may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

HorizSync 31.5 - 50.0

# HorizSync 30-64 # multisync
# HorizSync 31.5, 35.2 # multiple fixed sync frequencies
# HorizSync 15-25, 30-50 # multiple ranges of sync frequencies

# VertRefresh is in Hz unless units are specified.
# VertRefresh may be a comma separated list of discrete values, or a
# comma separated list of ranges of values.
# NOTE: THE VALUES HERE ARE EXAMPLES ONLY. REFER TO YOUR MONITOR'S
# USER MANUAL FOR THE CORRECT NUMBERS.

VertRefresh 40-90

To fully take advantage of your monitor you should set the HorizSync and
VertRefresh ranges to the exact ranges that are specified in your manual.
You might get the resolution that you want also with a lower value, but
then you will get a lower refresh rate which could result in flickering.
