Razer Synapse and Wallpaper Engine work together through a third-party plugin, not a direct built-in connection

Razer Synapse, which controls your Razer hardware lighting, does not natively connect to Wallpaper Engine. Instead, you use a community-built plugin called RazerChromaWallpaperEngine that sits between the two programs and translates Wallpaper Engine's visual output into lighting commands that Synapse understands. The plugin runs on your PC and watches what Wallpaper Engine displays, then sends that color data to your Razer devices in real time.

This setup means your keyboard, mouse, headset, or other Razer hardware will shift colors and effects to match what you see on your wallpaper. If your wallpaper is displaying warm oranges, your devices glow orange. If it shifts to cool blues, they follow. The connection happens through your local network or USB, depending on your Razer device type.

Key Takeaways

  • You need RazerChromaWallpaperEngine, a third-party plugin, because Razer Synapse has no built-in Wallpaper Engine support.
  • Both Razer Synapse and Wallpaper Engine must be running at the same time for the lighting sync to work.
  • The plugin reads colors from your Wallpaper Engine display and sends them to Razer devices via Synapse.
  • Your Razer device must support Chroma lighting (most modern Razer keyboards, mice, and headsets do, but older models may not).

Download and install RazerChromaWallpaperEngine

Go to the GitHub repository for RazerChromaWallpaperEngine and download the latest release. The project is maintained by community developers, not by Razer, so you are downloading from a third-party source. Look for the file named something like RazerChromaWallpaperEngine.exe or a .zip file containing it.

Extract the .zip file if needed, then run the .exe installer. It will ask you where Wallpaper Engine is installed on your PC (usually C:\Program Files (x86)\Steam\steamapps\common\wallpaper_engine) and where Razer Synapse is located. Point it to both folders, and the installer will place the plugin files in the correct locations. You do not need to uninstall or reconfigure Synapse or Wallpaper Engine itself.

Start Razer Synapse before launching Wallpaper Engine

Open Razer Synapse first and let it fully load. Make sure your Razer devices are detected and showing in the Synapse interface. If a device is not appearing, check that it is plugged in (for wired devices) or paired via Bluetooth, and that Synapse recognizes it. You should see your device listed under the Devices tab with its current lighting profile displayed.

Once Synapse is running and your devices are visible, launch Wallpaper Engine. The RazerChromaWallpaperEngine plugin will start monitoring Wallpaper Engine's output as soon as the program opens. You should not see a separate window or notification—the plugin runs in the background.

Verify the connection is working

Load a wallpaper in Wallpaper Engine that has visible color or movement. Watch your Razer devices to see if their lighting changes to match the wallpaper's colors. If you are using a dynamic wallpaper with shifting colors, your devices should shift along with it. If nothing happens, check that both programs are still running by looking at your taskbar or system tray.

If your devices are not responding, open Razer Synapse and confirm that Chroma lighting is enabled for each device. Some Razer products have Chroma support disabled by default. Look for a toggle or checkbox labeled "Chroma" or "RGB" in the device settings, and turn it on. Then check Wallpaper Engine again—the lighting should now sync.

Adjust color intensity and response speed if needed

RazerChromaWallpaperEngine usually runs with default settings that work for most setups. If the lighting feels too bright, too dim, or responds too slowly to wallpaper changes, you can edit the plugin's configuration file. This file is typically named config.json and is located in the plugin's installation folder.

Open the config.json file in a text editor like Notepad and look for settings like brightness, saturation, or updateRate. Lowering the brightness value will dim your devices; raising saturation will make colors more vivid. The updateRate controls how often the plugin checks Wallpaper Engine's display—a lower number means faster response but uses slightly more CPU. Save the file and restart both programs for changes to take effect.

Troubleshoot if devices are not syncing

If your Razer devices are not lighting up with wallpaper colors, first confirm that both Synapse and Wallpaper Engine are running. Check your taskbar and system tray to see if both programs are open. If one has closed, restart it and wait a few seconds for the plugin to reconnect.

Next, verify that your Razer device supports Chroma lighting. Older Razer products (before 2014) may not have RGB support, and the plugin cannot control devices that do not have it. Check your device's product page or manual to confirm Chroma compatibility. If your device is not Chroma-enabled, the plugin will not be able to control its lighting, and you will need to use Synapse's standard lighting profiles instead.

If your device is Chroma-compatible but still not syncing, try restarting Razer Synapse. Sometimes the plugin loses connection if Synapse crashes or updates. Close Synapse completely, wait 10 seconds, then reopen it. Launch Wallpaper Engine again and check if the lighting responds.

Understand what happens when you switch wallpapers

When you change wallpapers in Wallpaper Engine, your Razer devices will immediately begin reflecting the colors of the new wallpaper. There is no delay or manual step required—the plugin continuously watches Wallpaper Engine's display and updates your devices in real time. If you switch to a static wallpaper with one solid color, your devices will hold that color. If you switch to an animated wallpaper, your devices will animate along with it.

If you close Wallpaper Engine while Synapse is still running, your Razer devices will stop receiving color updates from the plugin and will revert to whatever lighting profile was last active in Synapse. The plugin only sends data while Wallpaper Engine is open.

Frequently Asked Questions

Do I need to pay for RazerChromaWallpaperEngine?

No. RazerChromaWallpaperEngine is a free, open-source project maintained by community developers. You download it at no cost from GitHub. Both Razer Synapse and Wallpaper Engine have free versions that work with the plugin, though Wallpaper Engine costs money if you want to use it beyond the trial period.

Will this work with wireless Razer devices?

Yes, as long as your wireless device is paired with your PC and showing up in Razer Synapse. The plugin communicates through Synapse, not directly with your devices, so it works with both wired and wireless Razer hardware that supports Chroma lighting.

What if my Razer device is not showing up in Synapse?

Check that the device is powered on and plugged in (for wired) or charged and in range (for wireless). Restart Razer Synapse completely. If the device still does not appear, try reinstalling the Razer device drivers from the Razer support website, then restart your PC and open Synapse again.

Can I use this with multiple Razer devices at once?

Yes. The plugin syncs all Razer devices that are detected in Synapse. If you have a keyboard, mouse, and headset all connected, they will all light up with the same wallpaper colors simultaneously.

Does the plugin use a lot of CPU or battery power?

The plugin uses minimal CPU—typically less than 1 percent on most systems. It does not significantly drain battery on wireless devices because Synapse handles the communication, and the plugin only sends color data, not constant commands. If you notice high CPU usage, check that Wallpaper Engine itself is not set to a very high resolution or frame rate, as that is usually the cause.
