I have dual monitors, and after installing windows 7 64-bit on a new hard drive, my monitor gets cut off on both the sides.

I tried adjusting it on the monitor itself, but did not work, and I also tried adjusting them through the monitor settings in control panel, but it refuses to stretch horizontally.

Is the proper display adapter driver installed and up-to-date? Is the display resolution set to the monitor's native resolution? – Ƭᴇcʜιᴇ007 Jun 1 '11 at 16:38
have to agree with techie007 it is likely that the install used different drivers. – datatoo Jun 1 '11 at 16:42

First, check that the driver is up-to-date.

Second, their may be quirks if you just updated. Sometimes changing your resolution and then changing it back can fix it.

Check the refresh rate in your display settings. Usually it should be around 60Hz but some monitors prefer higher rates.
