when i adjust my monitor resolution it blanks out and says "out of range"


My monitor - BENQ FP937s - is set at a low resolution because when i change it it doesnt work - comes up with a message "out of range". I cant work my "power producer" program because of the resolution. I have tried finding the driver but cant, its seriously doing my head in... how can i get it to work?

I looked up the specs:
Code:
Display

    * Diagonal Size 19.0 in
    * Dot Pitch / Pixel Pitch 0.294 mm
    * Max Resolution 1280 x 1024
    * Color Support Up to 16.2 million colors
    * Max Sync Rate (V x H) 77.0 Hz x 82.0 KHz
    * Video Bandwidth 135.0 MHz
    * Response Time 12.0 ms
    * Video Output None
    * Backlight Life 30000.0 hour(s)
    * Signal Input DVI-D, VGA
    * Features iKey
For LCD monitors, I would recommend using the native resolution, which is "1280x1024" in your case. Check your sync rates in /etc/X11/xorg.conf. Do they match the specs? Using a vertical refresh rate of 59 or 60Hz for LCD monitors is pretty standard. I don't know it the 70 Hz can be trusted. Anyway, the section to check looks like this:
Code:
Section "Monitor"
  Option       "CalcAlgorithm" "XServerPool"
  DisplaySize  332 187
  HorizSync    50-70
  Identifier   "Monitor[0]"
  ModelName    "1440X900@60HZ"
  Option       "DPMS"
  Option       "PreferredMode" "1440x900"
  VendorName   "--> LCD"
  VertRefresh  50-60
  UseModes     "Modes[0]"
EndSection
My laptops lcd monitor has a 16x9 display aspect ratio. Don't just copy my values.

What video card do you use, and which video driver are you using? Which distribution are you using? Some distro's have tools to help configure video, such as SuSE's sax2. Sometimes you need to install a non open source video driver before getting video working at the desired resolution.
