================== Dual Monitor Setup ================== The first step in getting OpenLP working on your system is to setup your computer properly for dual monitors. This is not very difficult, but the steps do vary depending on operating system. Most modern computers do have the ability for dual monitors. To be certain check your computer's documentation. A typical desktop computer capable of dual monitors will have two of, or a combination of the two connectors below. **VGA** .. image:: pics/vga.png **DVI** .. image:: pics/dvi.png A laptop computer setup only varies slightly, generally you will need only one of outputs pictured above since your laptops screen serves as one of the monitors. Sometimes with older laptops a key stroke generally involving the :kbd:`Fn` key and another key is required to enable the second monitor on laptops. Some computers also incorporate the use of :abbr:`S-Video (Separate Video)` or :abbr:`HDMI (High-Definition Multimedia Interface)` connections. A typical OpenLP set up consist of your normal single monitor setup, with your projector setup as the second monitor. With the option of extending your desktop across the second monitor, or your operating system's equivalent. Microsoft Windows ----------------- Dual monitor setup is similar among all the currently supported Windows releases (XP, Vista, Windows 7), but does vary slightly from one release to the next. Windows 7 ^^^^^^^^^ Windows 7 has using a projector in mind. Simply connect your projector and press :kbd:`Windows+P`. The more traditional way is also fairly straight forward. Go to :guilabel:`Control Panel` and click on :guilabel:`Display`. This will open up the :guilabel:`Display` dialog. You can also bypass this step by right click on a blank area on your desktop and selecting :guilabel:`Resolution`. .. image:: pics/winsevendisplay.png Then click on the :guilabel:`Adjust resolution` link in the left pane. Enable your projector and make sure that the selected value for :guilabel:`Multiple displays` is :guilabel:`Extend these displays`. .. image:: pics/winsevenresolution.png Windows Vista ^^^^^^^^^^^^^ From :guilabel:`Control Panel` click on :guilabel:`Personalize`, or right click a blank place on the desktop and click :guilabel:`Personalization`. .. image:: pics/vistapersonalize.png From the :guilabel:`Personalization` window click on :guilabel:`Display Settings`. Then enable the montior that represents your projector and make sure you have checked :guilabel:`Extend the desktop onto this monitor`. .. image:: pics/vistadisplaysettings.png Windows XP ^^^^^^^^^^ From :guilabel:`Control Panel` select :guilabel:`Display`, or right click on a blank area of the desktop and select :guilabel:`Properties`. From the :guilabel:`Display Properties` window click on the :guilabel:`Settings` tab. Then click on the monitor that represents your projector and make sure you have checked :guilabel:`Extend my Windows desktop onto this monitor`. .. image:: pics/xpdisplaysettings.png Linux ----- Due to the vast varieties of hardware, distributions, desktops, and drivers this is not an exhaustive guide to dual monitor setup on Linux. This guide assumes that you have properly set up any proprietary drivers if needed. You should seek out your distributions documentation if this general guide does not work. GNOME ^^^^^ This guide is for users of the GNOME desktop who do not use proprietary drivers. From most distros go to :menuselection:`System --> Preferences --> Display Settings (Monitors)`. Set up your projector with the correct resolution and make sure that :guilabel:`Same image on all monitors` is **unchecked**. .. image:: pics/gnome.png KDE ^^^ This guide is for users of the KDE desktop who do not use proprietary drivers. From most distros click the Kick Off menu and navigate to :guilabel:`System Settings` .. image:: pics/kdesystemsettings.png Click on the display and monitor icon. .. image:: pics/kdedisplay.png From here you will need to set up your projector with the appropriate resolution, and position. OpenLP works best projecting to the monitor on the right. Linux Systems Using nVidia Drivers ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ This guide is for users of the proprietary nVidia driver on Linux Distributions. It is assumed that you have properly setup your drivers according to your distribution's documentation, and you have a working ``xorg.conf`` file in place. If you wish to make the changes permanent in setting up your system for dual monitors it will be necessary to modify your ``xorg.conf`` file. It is always a good idea to make a backup of any critical file before making changes:: user@linux:~ $ sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old Or for those using systems that use the root user instead of sudo, change to root and enter:: root@linux: # cp /etc/X11/xorg.conf /etc/X11/xorg.conf.old The exact location of the ``xorg.conf`` file can vary so check your distribution's documentation. If you want to make your changes permanent run nVidia settings from the terminal:: user@linux:~ $ sudo nvidia-settings Or, as root:: root@linux: # nividia-settings If you do not want to write the changes to your ``xorg.conf`` file simply run the nVidia Settings program (``nvidia-settings``) from your desktop's menu, usually in an administration or system menu, or from the terminal as a normal user run:: user@linux:~ $ nvidia-settings Once you have opened nVidia Settings, click on :guilabel:`X Server Display Configuration`. Then select the monitor you are wanting to use as your second monitor and click :guilabel:`Configure`. .. image:: pics/nvlinux1.png After clicking :guilabel:`Configure`, select :guilabel:`TwinView`. Then click :guilabel:`OK`. .. image:: pics/twinview.png Then click :guilabel:`Apply` and if you are happy with the way things look click :guilabel:`Keep` to keep your new settings. Don't worry if all goes wrong the settings will return back to the previous settings in 15 seconds without any action. nVidia Settings should take care of selecting your optimum resolution etc, but that can be changed as needed. When you are happy with everything click on :guilabel:`Save to X Configuration File`. .. image:: pics/xorgwrite.png Then click :guilabel:`Save` and you should be set. You may want to restart X or your machine just to make sure all the settings carry over the next time you log in.
