It is not possible to change the graphics card because only known models are supported and these are detected automatically. However, you can change many options that affect the behavior of the card. Normally, this should not be necessary because the system already has set them up appropriately during installation. If you are an expert and want to tweak some of the options, click
next to the graphics card and select the option to change. To assign a value needed to a certain option, enter this value in the dialog that appears after selecting that option. Click to close the options dialog.To change the current settings for the monitor, click
next to the monitor. A new dialog opens in which to adjust various monitor-specific settings. This dialog has several tabs for various aspects of monitor operation. Select the first tab to manually select the vendor and model of the display device in two lists.

Although there are safety mechanisms, you should still be very careful when changing the allowed monitor frequencies manually. Incorrect values might destroy your monitor. You should always refer to the monitor's manual before changing frequencies. |
The resolution and color depth can be chosen directly from two lists in the middle of the dialog. The resolution you select here marks the highest resolution to use. All common resolutions down to 640x480 are also added to the configuration automatically. Depending on the graphical desktop used, you can switch to any of these later without the need for reconfiguration.
If you have a graphics card with two outputs installed in your computer, you can connect two screens to your system. Two screens that are attached to the same graphics card are referred to as dual head. SaX2 automatically detects multiple display devices in the system and prepares the configuration accordingly. To use the dual head mode of a graphics card, check at the bottom of the dialog and click to set the dual head options and the arrangement of the screens in the dual head dialog.
The tabs in the row at the top of the dialog each correspond to a graphics card in your system. Select the card to configure and set its multihead options in the dialog below. In the upper part of the multihead dialog, click
to configure the additional screen. The possible options are the same as for the first screen. Choose the resolution to use for this screen from the list. Select one of three possible multihead modes.Each monitor represents an individual unit. The mouse pointer can switch between the screens.
In this mode, all monitors display the same contents. The mouse is only visible on the main screen.
All screens combine to form a single large screen. Program windows can be positioned freely on all screens or scaled to a size that fills more than one monitor.

Linux currently does not offer 3D support for Xinerama multihead environments. In this case, SaX2 deactivates the 3D support. |
The arrangement of the dual head environment describes the sequence of the individual screens. By default, SaX2 configures a standard layout that follows the sequence of the detected screens, arranging all screens in a row from left to right. In the
part of the dialog, determine the way the monitors are arranged by selecting one of the sequence buttons. Click to close the dialog.![]() | Using a Beamer with Laptop Computers |

To connect a beamer to a laptop computer, activate dual head mode. In this case, SaX2 configures the external output with a resolution of 1024x768 and a refresh rate of 60 Hz. These values suit most beamers very well. |
If you have more than one graphics card installed in your computer, you can connect more than one screen to your system. Two or more screens that are attached to different graphics cards are referred to as multihead. SaX2 automatically detects multiple graphics cards in the system and prepares the configuration accordingly. By default, SaX2 configures a standard layout that follows the sequence of the detected graphics cards, arranging all screens in a row from left to right. The additional tab allows for changing this layout manually. Drag the icons representing the individual screens in the grid and click to close the dialog.
Click Ctrl+Alt+Backspace and reduce the refresh rate or the resolution and color depth.
