Hi, had the same problem. reboot/power cycle the machine, it works just fine. Both monitors worked fine.
Some minutes later, right monitor went blank. Bought new card ( and better video card too) Explained to the computer where the rubbish bin was. (this did not "help", but it relieved the angst somewhat). Wondered if it was because I had a 64 bit AMD dual core, and the driver was incompatible. == Inserted two digitial to vga adaptors on the card, one for each monitor. Slight loss of quality. Both monitors work full time now. That machine has an uptime of 233 days now. Will I go back to one monitor? Never. Programmers know you never have enough screen realestate. The loss in going to vga was worth it, to ensure I get dual monitors.
