Connect the cables
Connect the HDMI, USB and power cables. Turn on your PC and the display will show a second windows or mac desktop. The image displayed on the GNS530 will be inverted, to correct this you will need to adjust the display settings.
Configure the display
In Windows, open Display Settings and change the display setting for the smaller display to “Landscape / flipped”, set the resolution to whatever Windows says is recommended, usually 1280x720.
It is usually best to 'place' the GNS530 display below and to the center of your primary display. This makes it easy to adjust the GNS530 to exactly fill the display however if you have multiple other displays, this positioning may need to be modified.
Once downloaded and installed, you will see the the 'RealSimGear Device Interface' under the 'Add-Ons' menu. When your 430/530 is connected you will see it in the Device Interface window.
Hide the Bezel Graphics
Follow the instructions in the Reality-XP user guide for hiding the bezel. Essentially, you just need to go into the aircraft folder and edit the 'RealityXP.GNS' file and change the 'nobezel = false' to 'nobezel = true'
Start Prepar3D and once you have the Reality-XP 430/530 up and running, make sure that the option to 'Use Simulator GPS commands' is enabled under 'Advanced Settings'. To access these settings, hold down the shift key and right click on the Reality-XP 430/530 window.
Some Additional Notes
In order to position the 530/430 screen contents onto the 530/430 device, you will need to Undock the Reality-XP 530/430 window.
Once this is done, you can drag the window over to the 530/430 device screen, then simply click the maximize icon to fill the screen. There will be a white bar present at the top of the screen, however this will disappear once you enter full screen mode.
