1. Open Screen Resolution by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Display in the search box, tapping or clicking Settings, and then tapping or clicking Display.
   

2. Tap or click Adjust resolution.
   

3. Tap or click the Resolution list and find the resolution marked (Recommended). This is your monitor's native resolution-usually the highest resolution your monitor can support.
   

Screen Resolution in Control Panel shows the recommended resolution for your monitor.

Monitors can support resolutions that are lower than their native resolutions, but text won't look as sharp and the display might be small, centered on the screen, edged with black, or stretched.

This is not fixable by you and the cost by a professional is in most cases more than the cost of a new replacement.
Don't bother. Get a new one.

Do you have a spare computer to hook up to the monitor to see if the monitor's settings are off vertically?

Can you adjust the vertical size of the image of the monitor?

Are the letters squashed down vertically?

If the letters are squashed down vertically, did the setting for pixel size of the screen get adjusted to another size accidentally in the control panel under display settings?

Can you reset the Acer monitor from the menu?

check your video card for loose connections

Better to reinstall windows(Operating System) and drivers.

The link below is a Digitally signed M992 monitor driver. http://support.us.dell.com/support/downloads/download.aspx?c=us&cs=19&l=en&s=dhs&releaseid=R44148&formatcnt=1&libid=0&fileid=51992 Also try upgrading to the latest ATI software and drivers. You can also try and change the frequency refresh rate to 75mhz. It in the Control Panel under 'Display' and tab 'Monitor'. It shows a list for frequencies you can try.

Your monitor has a fault in the pincushion correction circuit. Most likely a bad solder connection, a failed diode or capacitor. I recommend you have a repair facility fix this one.
