How does it Work?
The Mirror Video Driver is a driver that UltraVNC (for instance) can use to be quickly and efficiently notified with screen changes. Using it on an UltraVNC server results in a excellent accuracy. The video driver also makes a direct link between the video driver frammebuffer memory and UltraWinVNC server. Using the framebuffer directly eliminates the use of the CPU for intensive screen blitting, resulting in a big speed boost and very low CPU load.
Supported OS for mv2 mirror driver?
If you have a previous version installed, it is recommended to uninstall it first, by doing the following:
Installation is done by
setupdrv.exe is located in the folder you've chosen during the driver installation.
net stop vnccom(stop communication manager service) Driver mv2 doesn't use the vnccom , only needed with the old drivers
- Under XP:
Control Panel ⇒ System ⇒ Hardware ⇒ Device Manager ⇒ Display Adapters ⇒ Uninstall mirror driver.
Under W2000: W2000 does not allow video drivers to be removed while running.
Trick: Remove vncdrv.sys (that is in system32/drivers), and reboot. You now can remove the driver the same way as with XP, via the device manager.
For each version the vncdrv.sys and vnccom.sys are a pair. Vncdrv.sys is a kernel driver, so can only be unloaded on reboot. After upgrading the driver, vncdrv.sys is still the old version, but vnccom.sys is already the new one. Switching of vncdrv.sys is done on reboot. Don't use the driver before you reboot.
