windows 8 second monitor bottom right corner of desktop is off screen

if the monitor is an analog VGA type, you will need to use the monitor auto adjust OR if the monitor does not support auto adjust, manually manipulate the height and width of the scan area for the monitor.

If the monitor is DVI or HDMI then your solution will be in the setting of the video card, not necessarily a windows 8 issue. Search through any utility application that came with the video card of the computer. Some allow you to adjust the vertical and horizontal frequencies to fit the scan lines to your specific device perfectly.

Thanks, it's HDMI.

Do you know how to set up the video card?  I looked around at all the settings in the display/monitor area and didn't see anything.  

It's a new Lenovo Yoga 2

Nice Laptop...

what monitor are you connecting?
My guess is that with the laptop your aspect ratios are different between the two screens and you will need to drop the resolution on the laptop screen to make it work on the external.

Thanks, it's pretty sweet, aside from this monitor issue.

I just set my laptop and monitor to the lowest res they could go at 1024*768 and I still have the issue.

It's a samsung syncmaster 2333HD.

Are you using them in extended desktop mode? In other words, the external monitor is an extension of the desktop of the laptop screen. Not cloned is a better way of putting it.
