Monitor Resolution Slightly Off

I own a Samsung television, 2 years old with - 1366x768 resolution. My problem is that Windows and the Nvidia Control Panel both think this has a resolution of 1360x768, 6 columns off. If I manually set the resolution to 1366x768 in the Nvidia control panel, it's all distorted, and it's not even one of the preset options. I'm connected via HDMI.

I need the extra 6 columns of pixels so I can properly setup Nvidia surround (I need the screens to be same resolution). My second LG display is 1366x768. Any help appreciated! Thanks guys.
 
Look for scaling options in the Nvidia control panel. Then increase the size that way to remove the black borders around the screen. That's what I have to do when I set my TV to 1080p. Though I have AMD graphics hardware, and the options for scaling could be slightly different. Maybe someone else can chime in that has an Nvidia card?
