Monitor Names Not Reported Correctly

I'm running a dual monitor configuration on an ATI HD 4670 card. My primary monitor is an Acer P191w, and my secondary monitor is a Dell E170S. Speccy incorrectly reports both monitors as being an Acer P191w. However, the desktop resolution difference between the 2 monitors (1440x900 vs. 1280x1024) is correctly reported. Both the Windows display settings properties tab, and the ATI Catalyst Control Center utility report the correct monitor names for the respective desktops.
