Hi johncrosno,
You are correct, you should have a full display. Have you upgraded to Win 8.1?
Explain upgrade path. There are many variables involved. Graphics drivers have caused issues.
Best guess is incorrect Nvidia drivers or setttings in Nvidia Control Panel.
Here is a link to current Nvidia drivers for Win 8.1 64 bit drivers for a 630 card.
Using this link, Select "start search", then select "Geforce R331 Game Ready Driver" - WHQL 11-19-2013.
