Introduction to Multi-Display Cockpits in Prepar3D with AeroSimulations Aircraft

Building a multi-display cockpit for Prepar3D (P3D) is one of the most rewarding upgrades you can make to your flight simulation setup. By spreading the virtual cockpit across multiple monitors, you gain a panoramic field of view, better situational awareness, and a level of immersion that a single screen simply cannot deliver. This is especially true when flying high-fidelity add-ons like AeroSimulations aircraft, which are designed with detailed instruments and exterior views that benefit from extra screen real estate.

However, configuring multiple displays correctly requires a structured approach—from hardware selection to in-simulator tweaks. This guide provides a comprehensive, step-by-step walkthrough to help you set up a seamless multi-display environment in P3D for AeroSimulations aircraft. We will cover everything you need, from prerequisites and physical mounting to advanced synchronization tools and performance optimization.

Prerequisites and Equipment

Before diving into configuration, ensure your system meets the demands of multi-monitor flight simulation. The following checklist covers essential hardware and software:

  • Multiple displays – Ideally three or more monitors of the same resolution, refresh rate, and bezel thickness for a uniform look. 24–27 inch screens with 1920×1080 resolution are a popular starting point.
  • Graphics card – A GPU with at least three video outputs (DisplayPort, HDMI, or DVI). For smooth performance, an NVIDIA GeForce RTX 3060 or higher (or AMD Radeon equivalent) is recommended. Multi-GPU setups (SLI/Crossfire) are no longer widely supported by P3D, so a single powerful card is often better.
  • Prepar3D v4 or v5 – The latest version of P3D (v5.4 as of writing) offers improved multi-monitor support and performance. Ensure you have the most recent update installed.
  • AeroSimulations aircraft – For example, the AeroSimulations A320, B777, or their regional jet products. Have the add-on fully installed and activated.
  • Mounting hardware – Monitor arms, a purpose-built cockpit frame (e.g., from Trak Racer or Next Level Racing), or DIY solutions. Alignment is critical for a seamless image.
  • Optional third-party tools – WideView, SimVimX, EZ-Dok, or ChasePlane for view synchronization and instrument pop‑outs.

Physical Setup and Display Configuration

Monitor Positioning and Bezel Correction

Arrange your monitors in a curved or flat configuration depending on your space and preference. For a typical three‑screen setup, position the side monitors at a 45–60 degree angle relative to the center screen. This mimics the field of view of a real cockpit. Bezel correction is crucial: measure the thickness of the bezels (in mm) and adjust the P3D view settings to compensate. Without this, instruments and objects will appear misaligned where the monitors meet.

Windows Display Settings

  1. Open Display Settings in Windows (right-click desktop → Display settings).
  2. Identify each monitor and arrange them to match your physical layout. Drag the monitor icons to reflect the order (e.g., left, center, right).
  3. Set each display to Extend these displays (do not use Duplicate).
  4. Match resolutions and refresh rates across all monitors. If they differ, set all to the lowest common resolution for consistency.
  5. If using NVIDIA Surround or AMD Eyefinity, you can combine the monitors into a single logical display—this simplifies P3D setup but may reduce flexibility for undocked panels.

After configuring Windows, open your graphics card control panel and confirm the display order. Many users prefer to set the center monitor as the primary display; this is where P3D will place its main menu and default views.

Configuring Prepar3D for Multiple Displays

Enabling Multi-Monitor Mode

  1. Launch P3D and go to Options → Settings → Display.
  2. Under the Full Screen section, set Full Screen Mode to On.
  3. Ensure Multi-Monitor Mode is enabled (check the box).
  4. Set the Primary Monitor to your center display.
  5. For the Aspect Ratio, choose Wide if your combined resolution exceeds 16:9 or 16:10.

These settings allow P3D to use all connected displays as a single extended desktop. However, for maximum control over camera views and instrument panels, you may want to use P3D’s advanced multi-window features.

Using View Groups and Undocked Panels

P3D supports view groups that let you assign specific camera views to different monitors. This is ideal for AeroSimulations aircraft where you want the virtual cockpit on the center screen and side views (e.g., left/right window) on the side monitors.

  1. Launch your flight and load the AeroSimulations aircraft.
  2. Press Shift + Z to open the view options or go to Views → View Groups.
  3. Create a new view group (e.g., “Cockpit + Side Views”) and drag the views to the desired monitor positions.
  4. For instrument panels, you can undock them by right-clicking an instrument and selecting Undock. Drag the undocked window to a separate monitor.

Many AeroSimulations aircraft include dedicated 2D panels (often found in the Aircraft → Panel menu). These panels can be undocked and stretched across monitors to create a complete instrument panel spanning multiple screens.

Adjusting the Virtual Cockpit View

To properly align the virtual cockpit across monitors, you need to adjust the Field of View (FOV) and Lateral Offset.

  • FOV: In P3D, press Ctrl + Shift + F to open a FOV slider. For a three-monitor setup, a typical FOV is 110–130 degrees. Adjust until the cockpit feels natural when you look left and right.
  • Lateral Offset: If the center monitor shows the same area as the side monitors (overlap), use Shift + Left/Right Arrow to pan the view. Alternatively, edit the CAMERA.CFG file for precise offset per aircraft. The file is located in %APPDATA%\Lockheed Martin\Prepar3D v5\.

For perfect bezel compensation, you can add the following entry to each camera definition in CAMERA.CFG:

BezelOffset=0.015
BezelHeight=0.010

The actual values depend on your bezel width. Start with small increments (0.005) and adjust until the image across the seam looks continuous.

AeroSimulations Aircraft-Specific Configuration

Checking for Native Multi-Display Support

AeroSimulations aircraft often ship with configurable panel files. Open the aircraft folder (e.g., \SimObjects\Airplanes\AS_A320) and look for panel.cfg or a dedicated views.cfg. Some aircraft include pre-made views for left/right side windows; you can copy these into your P3D camera configuration for quick access.

Configuring 2D Panels for Multi-Monitor

For glass cockpit aircraft (like the AeroSimulations A320 or B777), the main display panels (PFD, ND, EICAS) can be undocked and positioned on separate monitors. Follow these steps:

  1. Load the aircraft and go to Views → Instrument Panel.
  2. Select the pop‑up panel you want (e.g., Captain’s PFD).
  3. Right-click the pop‑up and choose Undock.
  4. Drag the undocked window to your secondary monitor. You can resize it to fill the screen if desired.
  5. Repeat for each instrument you want on separate screens. Save the panel layout by creating a Panel State via the Aircraft → Panel States menu.

Note: Some AeroSimulations aircraft may require you to enable multi-display support in their own configuration utility (found in the start menu or P3D add-on menu). Check the aircraft manual for specific instructions.

Utilizing Virtual Cockpit Views for Externals

If you prefer flying with the virtual cockpit, create dedicated camera views for the side windows. In P3D’s Camera Manager (accessible via the Views menu or Ctrl + F9), add new cameras with an offset of +90 degrees (right view) and -90 degrees (left view). Assign these cameras to the side monitors using view groups.

Advanced Multi-Display Tools and Synchronization

For a truly seamless cockpit, third-party tools can help synchronize visuals across monitors and even allow you to use mobile devices as additional displays.

WideView

WideView is a popular solution that creates a network‑based multi‑display system. It allows you to run P3D on separate computers for each monitor, reducing the load on a single GPU. WideView is particularly useful for large cockpit builds (e.g., 3+ screens) and provides automatic view alignment.

To use WideView with AeroSimulations aircraft, you need to configure the client machines to run P3D with identical aircraft and weather settings. WideView handles the camera synchronization, making it appear as one seamless view.

SimVimX

SimVimX is an open‑source tool for building custom hardware panels and instrument displays. It can also export aircraft data to additional monitors or tablets, allowing you to create dedicated instrument screens that mirror the AeroSimulations cockpit gauges. This is ideal if you want to offload glass displays to smaller screens while keeping the main monitors for the outside view.

EZCA or ChasePlane

These camera add‑ons (e.g., ChasePlane) offer advanced view control and can save per‑aircraft camera profiles. With them, you can quickly switch between multi‑monitor layouts and save custom views for each AeroSimulations aircraft.

Performance Optimization for Multi-Display

Running P3D across multiple monitors is demanding. Follow these tips to maintain smooth frame rates:

  • Adjust rendering settings – Lower the autogen density, shadow quality, and scenery complexity. The panoramic view increases the number of objects rendered simultaneously.
  • Set fps limit – Cap frames at 30 or 40 in the P3D settings to reduce GPU load and avoid micro‑stutters.
  • Use DSR or supersampling – If you have headroom, enabling NVIDIA DSR can improve image clarity without significant performance loss compared to native 4K.
  • Monitor GPU utilization – Use tools like MSI Afterburner to identify bottlenecks. If your GPU is maxed out, consider lowering anti-aliasing (use 2x or FXAA instead of MSAA).
  • Try single‑GPU surround – For some setups, enabling NVIDIA Surround can reduce overhead by treating the displays as one surface.

AeroSimulations aircraft can be resource‑intensive due to detailed textures and systems. If you experience poor performance, temporarily disable the aircraft’s custom VC texturing and use the default high‑resolution option in the aircraft configurator.

Troubleshooting Common Issues

Views Not Spanning Correctly

If the virtual cockpit appears stretched or duplicated, re‑check your Windows display ordering and P3D primary monitor assignment. Also ensure that the multi‑monitor mode is enabled. A common mistake is accidentally setting the side monitors to “Portrait” orientation – they must be in Landscape.

Instrument Panels Not Undocking

Some AeroSimulations aircraft limit which panels can be undocked. Try opening the panel via the menu (e.g., “Captain’s PFD”) instead of clicking on the VC instrument. If undocking fails, restart P3D and load the aircraft again—this sometimes resets panel state permissions.

Bezel Compensation Causes Overlap

If the image overlaps or has a gap, adjust the BezelOffset values incrementally. The values should be positive to shift the image outward (toward the bezel). Test with a vertical line (like a window frame) to fine‑tune.

Performance Stutter in Multi‑Window Mode

Using multiple undocked windows can cause stuttering. Try enabling Use High Precision Timer in P3D settings, and set the Target Frame Rate to 30. If problems persist, switch to view groups instead of undocked panels.

Conclusion

Setting up a multi‑display cockpit in Prepar3D for AeroSimulations aircraft takes careful planning, but the reward is a truly immersive flight environment that mirrors the expansive views of the real sky. By following the steps outlined above—from hardware selection and bezel compensation to P3D display settings and third‑party tools—you can create a configuration that feels natural and handles crisp visuals without overwhelming your system.

Remember to test your setup thoroughly: adjust FOV, save panel states, and create view group presets for each AeroSimulations aircraft you fly. With patience and the right approach, your multi‑monitor cockpit will transform your simulation experience from a constrained window into a panoramic flight deck.
