Last week there was a rather problematic issue when I tried to clone the display to two monitors. The display card, unfortunately, is ATI X600, a rather outdated piece IMHO but I could do nothing about it.
The goal was to clone the display to a TV, which Windows XP refuses to recognize as monitor, if XP ever recognized it at all (it didn't show up in the hardware list).
At first I didn't install ATI Catalyst Control Center, only fooled around with XP display settings. I discovered that it works with another standard monitor, but I could only extend the desktop onto it. And the TV just kept showing "no signal". Then I installed ATI Catalyst Control Center and tried to clone the display to TV, but even the Control Center didn't recognize the TV, while it recognizes a standard monitor.
The final solution, or workaround:
- Connect to TWO standard monitors, make sure the Control Center recognizes both.
- Set the display to CLONE MODE. Apply settings.
- Simply unplug one of the two monitors and plug in the TV. TV should be showing the same thing as the monitor.
Later I found out that if you restart, even with the TV plugged in, the Control Center will not recognize the TV. So every time you restart you have to go through above 3 steps again. But logging off is OK.
