This is an announcement for an open-source tool to use the TV-Out capabilities of NVidia graphic cards on Linux. The closed-source drivers by NVidia already allow TV-Out, but only in a limited way: Only two resolutions are supported, overscan compensation (the size of the image on the TV) cannot be adjusted, the video overlay does not work on the TV, and there is no way to control the flicker filters and other image processing capabilities the TV encoder chip offers. This tool was written to overcome these limitations, inspired by TV-Tool (http://www.tvtool.de/) that offers a similar functionality for Windows. Features include: * Arbitray resolutions, as far as the encoder chips supports them. * Arbitray overscan compensation, with the same restriction. * Multiple TV encoder chip support (So far Brooktree, Conexant, Chrontel and Philips chips, and other chipsets can be added easily). * Autodetection of TV encoder chip and PCI card. * Control display parameters like brightness, saturation, contrast, flicker filter, or bandwidth. * Graphical user interface and command line support. * Switching X video modes. * Centering and resizing an X window on the X virtual viewport. * Control downto direct register access. The project is in the alpha stage, so there may be still bugs, and some features need more work. However, since it is open source, you may contribute to fix bugs and add functionality. The project is located at Sourceforge. If you are interested, have a look at http://sourceforge.net/projects/nv-tv-out/
