The vttimer.exe process is a part of the device driver files for the graphics cards’ KN400 and VIA/S3G KM400, which is partially responsible for allowing in and out functionalities of a television’s video card. Supported by this EXE file, is the Unichrome IGP (Integrated Graphics Processor), a product in conjunction with the efforts developed between VIA and S3, supporting both the models of Intel and AMD processors. This process is installed alongside the device driver, S3 chipsets, to provide enhanced diagnostics and functional capabilities for the graphics card engine. The vttimer.exe process runs within the S3 Screentoys application in support of the video card models of KM400 and KN400, both of which were created in order to cater to a variety of AMD processor models. This EXE file provides support for the functional use of the main graphics engine of video cards that are placed on a PCI card architecture or the motherboard.
