    - Before you begin
      This guide is intended to describe how to integrate a new display by setting the appropripate parameters based on your display specifications.
    - Introduction to the Wfdcfg library
      The Wfdcfg library provides the modes and attributes of your display hardware to your display driver and Screen.
    - Getting the source code
      The files from the compressed Wfdcfg archive are extracted onto your host.
    - Setting timing parameters
      Timing is mandatory component of a mode.
    - Updating Wfdcfg source (adding extensions)
      You may want to update your Wfdcfg source if your display supports specific options that you want to control.
    - Building the Wfdcfg library
    - Updating your target
      After you've completed updating and building your Wfdcfg library, you are ready to rebuild your QNX IFS and transfer it to your target.

      You need to configure your display in graphics.conf and restart Screen.
    - OpenWF Display Configuration Library Reference
      The Wfdcfg library provides the modes and attributes of your display hardware to your display driver and to Screen. Your display driver (WFD driver) is the primary user of the Wfdcfg library, but the composition manager component in Screen also uses the modes and attributes from the Wfdcfg library.

Configuring Screen for your display

Graphics and Screen4.0 (8.x)OpenWF Configuration Developer's GuideAPIProgramming

You need to configure your display in graphics.conf and restart Screen.

Configuring `wfd device` section

In your configuration file (graphics.conf), on your target, you need to specify the Wfdcfg library (or libraries) and any parameters related to your display device. In the wfd device section, ensure that you have the appropriate libraries specified for your display. For example,

  begin wfd device 1
    wfd-dlls = libwfdcfg-imx6x-okaya.so libimx6xCSCgamma-generic.so libWFDimx6x.so
    grpx0 = lcd
    grpx1 = hdmi
    grpx2 = hdmi
    video-layer0 = lcd
    video-layer1 = hdmi
  end wfd device

You need to configure one wfd device section for each display you are using.

For more information on configuring Screen, refer to the Screen Developer's Guide.

Restarting Screen

Ensure the following:

Your target hardware is running QNX Neutrino RTOS.
On your target, you can run a shell and commands such as pidin.

To apply your new display configuration:

On your target, from the command line, stop screen by using the following command:
```
slay screen
                    
```
You can verify that the screen process is no longer running by using the following command:
```
pidin ar
                    
```
If not already set, ensure that your LD_LIBRARY_PATH is set to correct paths..
Restart screen.
```
screen
                   
```
Verify that there were no warnings generated from your new configuration by using the following command:
```
slog2info
                    
```
Use any of the available sample Screen applications to verify that your display has been correctly integrated for use with your target. For example:
```
sw-vsync
                    
```

For more information on applying your Screen, configuration, refer to the Screen Developer's Guide.
