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 The display card, unfortunately, is ATI X600, a rather outdated piece IMHO but I could do nothing about it.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.

The problem was that my mac pro failed to "software update", and whatever .dmg files downloaded from internet failed to mount, always gave "codec overrun" error. Moreover, some images from web pages couldn't display properly, either some colors were lost, or the image file couldn't display at all, because there was an error opening or downloading the file.
I first thought this problem was caused by some hardware problem, because my mac pro had been badly treated by me. But it wasn't. Because I tried reinstalling the whole system, and for some reasons it worked for like 5 or 6 days then this problem occurred again. So it's not because of the hardware.
Then I found this very interesting discussion, it's about the same issue I had, so I checked it out, and figured this problem should be caused by the network settings.
So first I disabled Internet Sharing, and now I can finally mount those .dmg files! Of course I re-downloaded them, because Disk Utility verified it as "corrupted". I was using iGetter all the time.
But then the images still couldn't display properly. At this time, my network also had a printer, an Airport (as a bridge), a PC, and a MBP (that worked fine), and lastly a Linksys router w/ 4-port switch. I figured maybe these "non-computer" machines were causing problems. So I unplugged their internet cables. And the problem is solved!

Something really important here, even the above solution worked for me, it probably wouldn't work in another situation...But, the point is, I don't think this problem is caused by any part of the hardware in my mac pro.
