Resolution capabilities are a complicated blend of the abilities of your graphics card and the abilities of your screen. You will not always get a 1:1 match. You can improve your chances by installing the "monitor information" file that is usually supplied on a CD that comes with the monitor. Also, updating the drivers for your graphics card (see the manufacturer's web site) might help.

You need to set your PC video resolution to the native resolution of this monitor, which is 1440x900 @60Hz. Mkae sure to to have correct video card driver installed and may also need the driver for this monitor if the native resolution is not listed.

Your resolution is set above what the monitor supports.

when computer is first starting up hit f8 to get to boot modes.

choose Enable VGA Mode: This option starts Windows in 640 x 480 mode by using the current video driver (not Vga.sys). This mode is useful if the display is configured for a setting that the monitor cannot display.

When you are booted into windows you can then set your resolution to the highest that the monitor supports which is 1440x900

Let me know if this helps.

Find your monitor's native resolution, in your case it's 1440x900. Go to display settings (usually right-click on desktop and choose properties), go to settings tab and move the resolution slider until it shows 1440x900. Confirm, the screen should flicker for a moment and adjust - and you should be fine.
If there is no 1440x900 resolution available, then installing a monitor .inf file that came on a disk accompanying the monitor might help.

What resolution are you trying to run? The native resolution for your monitor is 1440 x 900, setting to that should fix your issue

Most likely the resolution of your desktop has and aspect ratio that in incorrect for your monitor. The native resolution of that monitor if 1440x900. Use the Windows (if using windows) desktop properties to set the desktop resolution to 1440x900.

Try useing a different resolution. The native resolution should probable be 1280 x 1024. Try updateing the video drivers.

The AL1916W's native resolution is 1440 x 900. See if your display settings can produce that resolution.
