I found that this bug happen on windows 7 64bit and windows 8/8.1 too. Try unsing this method from the video. Maybe is somthing went wrong with your monitor settings and now you hav a duplicate monitor. Follow all the video steps and it should fix it.

If this doesn't work follow use this method instead:
1. Copy the directory Red Alert 2 (Typically found in C:\Program Files (x86)) to somewhere outside of Program Files
2. Download the graphics patch from http://www.stuffhost.de/files/cnc/ and extract it into the directory that you just moved
3. Rename Yuri's Revenge to gamemd.exe, then run the patch to patch the game (for ra2, rename to game.exe)
4. Download http://bitpatch.com/ddwrapper.html zip file and extract the files to the directory that you've patched the game in
5. Edit aqrit.cfg in notepad and change these two settings to 1 as in below:
NoVideoMemory = 1
forcedirectdrawemulation = 1
6. Create a shortcut to the game and move it to your desktop
7. Go to properties and in 'Target' add at the end after " add -win
example Target: "C:\Users\Roberto\Desktop\Red Alert 2\gamemd.exe" -win
note the space between gamemd.exe" and -win
8. In the same Properties Tab:
Compatibility : Win Xp Service pack 2 (Seems to be most stable)
Reduced colour mode : 16bit
Run as Administrator
9. (Optional) Edit .ini file to change the resolution
10. Play the game
