Check to make sure you have the resolution set to the monitors native resolution, what ever that may be. My two samsung monitors have a native resolution of 1600x900. Right click any where on blank screen, select screen resolution and in resolution tab, make sure the recommended is the one being used. Next thing to check it the zoom, make sure it's set at 100% - in and open IE browser, click the cog wheel, then click zoom and set to 100%.
