Here's another sample point submitted by someone else for an ATI= Radeon 8500 dual head. GetSystemMetrics( SM_CMONITORS ) reports 2 monitors \\.\DISPLAY1, "RADEON 8500 SERIES", attached, primary \\.\DISPLAY1\Monitor0, "Plug and Play Monitor" - attached \\.\DISPLAY1\Monitor1, "Plug and Play Monitor" - attached, multidriver \\.\DISPLAY2, "RADEON 8500 SERIES", attached \\.\DISPLAY2\Monitor0, "Plug and Play Monitor" - attached, multidriver \\.\DISPLAY2\Monitor1, "Plug and Play Monitor" - attached This is fairly alarming, because to a naive multimon inspection= it looks like there are two adapters, each with two monitors. Both= adapters are marked as attached, and each has two attached= monitors. The only difference is that the "multidriver" bit is set in the= flags field, which NVidia does not set anywhere that I'm aware of. This isn't a documented bit for the DISPLAY_DEVICE::StateFlags structure, so I'm not even sure what it means other than it's= related to multihead adapters somehow? Brian |
