Windows 7 Dual Monitor and Full Screen Video Problem

[dotsr]

Hello,

I am using dual monitor software Ultramon and it's working fine with all the folders and software. But when I try to see video by using windows media player or VLC player, the video doesn't fit in dual monitor properly. The video shows in the middle of the two monitors and both monitors show black screen at the end. Here is an screen shot; where you can see the problem:



Is there any way to fix this problem?

Thanks

SR
