Dual Monitor drivers

Hello,
I have a dual monitor setup. A samsung 2333SW widescreen LCD and an old CRT. I did the dxdiag in the run menu and was looking at my settings when i noticed that my primary display, the samsung, was listed as "Monitor : Generic PnP Monitor" and my old CRT was listed as "Monitor : SyncMaster 2333SW."
It's under the device description (Display 1 and Display 2 tabs) and they both are using the same driver as far as i can tell.
So why does it think the LCD is the old monitor and the CRT is they samsung? Everything seems to be working fine and looks great. Should i delete the standard default monitor driver, the generic PnP driver, since i have the replacement drivers that came with my graphics card?
