3. Setup and Installation
This adapter allows you to extend a VESA 200x200 mount to support larger VESA patterns. Follow these steps for proper installation:
- Identify VESA Patterns: Determine the VESA mounting pattern of your display and your existing mount. This adapter is designed to convert a 200x200 mount to 300x100, 300x200, or 300x300.
- Attach Adapter Arms to Mount: Secure each of the four adapter arms to the existing VESA 200x200 pattern on your wall mount or stand. Use the provided screws that best fit your mount. Ensure all connections are tight and secure.
- Attach Display to Adapter Arms: Align the VESA mounting holes on the back of your display with the appropriate holes on the extended adapter arms. The adapter arms feature multiple holes to accommodate 300x100, 300x200, and 300x300 patterns. Use the provided screws to firmly attach the display to the adapter arms.
- Verify Security: After installation, gently test the stability of the mounted display. Ensure all screws are tightened and the display is securely attached to the adapter arms and the mount.

Important Note:
Ensure that the screws provided or those you use are of adequate length to securely fasten both the adapter to the mount and the display to the adapter, without stripping threads or leaving connections loose. Some installations may require specific screw lengths not included in the standard package.
4. Operating Instructions
The RiteAV VESA 300 Adapter is a passive component. Once correctly installed, it functions by providing the necessary VESA pattern conversion, allowing your display to be securely mounted to a compatible VESA 200x200 mount. No further operational steps are required for the adapter itself.
5. Maintenance
The VESA adapter requires minimal maintenance. To ensure continued safety and stability:
- Periodic Inspection: Periodically check all mounting screws and connections for tightness. Vibrations or movement over time can sometimes loosen fasteners.
- Cleaning: If necessary, wipe the adapter arms with a soft, dry cloth. Avoid abrasive cleaners or solvents.
6. Troubleshooting
If you encounter issues during or after installation, consider the following:
- Display Not Fitting: Double-check that your display's VESA pattern is one of the supported conversions (300x100, 300x200, 300x300) and that your existing mount is VESA 200x200. Refer to Image 3.1 for visual guidance on pattern alignment.
- Loose Connections: Ensure all screws are fully tightened. If screws feel loose or do not engage properly, verify that you are using the correct screw size and length for both the adapter-to-mount and display-to-adapter connections.
- Missing Parts: If any components were missing from the package, contact RiteAV customer support for assistance.
