RECentral 4 fails to start and shows following error message on computer with Windows 10 Spring update [1803]

This error is resulted by the new Windows 1803-update that controls the way of applications connecting your webcams and video capture devices.

Please refer to following steps to resolve the situation:



In Windows Search type “Privacy Settings” then click “Enter”



At Privacy Settings/ App Permissions/ Camera find the toggle and make sure to set it on

“Allow apps to access your camera”

With this setting you can get your AVerMedia capture card detected by RECentral 4.

If you want to output audio from gaming PC to your headset and to your AVerMedia game capture card simultaneously please follow steps detailed below:


1. Open “Settings” => “Sound” and enter the “Sound control panel”


2. At “Sound control panel/Recording”, “the stereo mixing device” might won’t show up at the first time. In this case right click on the mouse and check out the "Show disabled devices" option. The “stereo mixing device” will appear. However, the device at this point should be grayed out, make sure to enable it and click on apply.


After you clicked twice on the stereo mixer with the left mouse button, the following picture will appear. Please select the device usage mode field to enable, and then click Apply.


3. Then click to “Listen”, the below picture will show up, please check out "Listen to this device" and select the Digital output in the "Playback through this device" field.


4. Then set the stereo mix volume level to the appropriate level.


5. Select the Advanced panel and select "2 channels, 16 bits, 48000Hz (DVD quality)" in the Default format field. In general the HDMI PCM will provide the following sampling rate values: 44100, 48000, 96000, 192000Hz.


6. Finally, set the playback device to the "analog speaker" output, and that's it!


The above principle is focusing on the analog built-in mixer, so the computer's playback device must be set to analog speaker output, using the analog mixer on the output to the digital HDMI sound device (in this case the AVerMedia game capture card). Kindly note that the reversed setting will not work, because the sound card and the display card are different devices, and the HDMI of the display card does not support the digital mixer.

This error is received when you're about to capture from your PC (either Current or Other PC setup) and your AMD GPU is set to HDCP on mode. In order to fix the situation please enter AMD Radeon utility Display settings and make sure to disable HDCP as shown on below screenshot.

Please make sure you’ve installed LGX’s driver, once you’ve installed the driver successfully you’ll be able to output the pass-through video.
As LGX is a software compression capture box, it occupies higher CPU usage when recording HD videos. To ensure the recorded quality, make sure the CPU Usage does not go over 70% while recording the video. Try closing other programs to lower the CPU usage.
Please update your the USB 3.0 chipset driver on your computer to the latest version.
Usually this does not happen, we recommend you to close and reopen RECentral 2 and your screen should resume normal display. If you still see a black screen, the source signal may be protected by HDCP. LGX does not support the viewing/recording of HDCP protected signals.

32-bit operating systems limit the maximum RAM to 4 GB, and streaming software consumes a lot of memory, especially when using functions such as overlays.
As such, performances of streaming software (including RECentral, OBS, or XSplit) will be impaired, and may even lead to abnormal behaviors.

Therefore we recommend running streaming software under 64-bit operating systems with at least 8 GB of RAM to get a sufficient share of memory when running the program.
Please follow steps as detailed below to complete the setup:

Step 1:
Connect LGX to your PC’s USB 3.0 with the supplied USB 3.0 cable.
*we recommend to use onboard native Intel USB 3.0 host controller
(before the setup make sure to run Windows update, furthermore install latest drivers for USB 3.0 controller and graphic card)

Step 2:
Download and install latest driver and RECentral from AVerMedia official website

Step 3:
