I have my mine computer monitor. A HP w2007 with DVI input as my main monitor. I then hook up my LG 42LE5300 HDTV to my computer using simple VGA. I used to be able to enable/disable it with no problems using ATI Catalyst Control Center. The only thing that i can think of that might of caused this is that ive made my tv, my primary screen to play games on it. Ever since i havent been able to disable it. Yet now i can disable my HP monitor.

Question: How can i put back my HP monitor primary and disable my LG TV screen.

PS, ive tried un-hooking the vga from back of computer. restarted. still did nothing.
Ive tried the obviouse way. ( ATI catacyst ) (Windows control panel option) still nothing.
Even tho my HP is primary, i still unable to disable my TV. Yet im able to disable my HP(Pimary monitor)

Cheers
