You can try using the Intel Media Control Panel program that installs when you install the full Intel HD Graphics 4000 package. It has some scaling options that may alleviate the issue. You can get that here.
**Poster states that this fixed the issue:
- Right click the Intel icon near the time on the desktop that appears after the installation and reboot
- Choose Graphics Options->Panel Fit->Scale Full Screen.
