When I put my TV above my monitor at the display configuration, and then try to maximize something at my TV, the window bugs.

[Marcos C Santos]

I have a Sony 72"(1920x1080, 16:9) TV, pluged to my PC with HDMI. And I have a Monitor(1280x1240 5:4) pluged with a VGA. So, when I'm using both screen, one next to the other everything works just fine. But when I try to put at Display Plug that my Sony TV should be on my monitor, it works, but not as it must be, I mean, when I try to maximize some window at my TV, with this configuration, the window bugs and resize itself in a weird size.
