Under Windows 7 World of Warcraft can not solve the full screen problem

After installing Windows 7, there has been no chance to play World of Warcraft. When I was on a business trip the day before yesterday, my roommates were bothering to play dota together, but when I started war3, I found that something was wrong. The interface of Warcraft could not be full screen. The two sides of the display were big black bars!
This problem was also encountered on Windows XP before. However, it is because of the graphics card model or graphics card driver. North Street's notebook is an integrated N card, so war3 supports widescreen solution as follows:
In the "Start" &ndquo; “ “ Run & rdquo; enter RegEdit, enter [HKEY_CURRENT_USERSoftwareBlizzard EntertainmentWarcraft IIIVideo]
set appropriate The “reswidth” and “resheight” key values ​​are fine, pay attention to the following "decimal”.
