Based on a monitor profile, it will provide the best video mode for a given width, height, and refresh rate. + +The usual motivation is to connect a CRT display and have it driven in the original resolution (at least vertically), which is otherwise too low for modern display systems. The connection is typically from a digital connector (such as HDMI) on the computer side and needs an external converter for the CRT. + ## Setup ### Windows -Windows works the best with CRT Emudriver, available [here](https://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=295). Once you have this setup and running, it is a simple case of turning CRTSwitchRes on and choosing your settings. +AMD video card is needed. Windows works the best with CRT Emudriver, available [here](http://geedorah.com/eiusdemmodi/forum/viewtopic.php?id=295). Once you have this setup and running, it is a simple case of turning CRTSwitchRes on and choosing your settings. Other options are available. It's a simple case of getting the resolutions installed on you Windows PC. ### Linux -No pre setup required here, although X11 is a requirement at the moment. Simply install/compile RetroArch choose you CRTSwitchRes setting, and you're off. +Switchres can work in the following environments: +- X11 +- KMS mode +- Raspberry Pi with legacy graphics drivers !!! note In some cases your distribution may be missing some X libraries in this case make sure you install the following `libx11-dev libxrandr-dev` -This is also compatible with Raspberry Pi, X11 is not a requirement here. +!!! note + The composite output of RPi has fixed resolution and is unsuitable for custom modelines. ## Enabling and Changing Settings
