Live Gamer 4K - GC573

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.

On some platforms the video preview might not be so smooth. In order to improve on video preview experience please enter RECentral 4/Settings/General and under Display Performance enable VSync. Note however that with this setting activated the latency will increase slightly (about 30 to 70 ms).

The error message shows as following



After selecting “P010” at Color space/Compression options the “AVerMedia HD Capture GC573” device will cease to function. In order to get it work please first remove it from the Source tab then add it again.

Make sure to select other available options such as YUY2, NV12, RGB24


This is a known issue: in case you select output resolution value that supports higher than 60fps, XSplit won’t allow to select 60fps or higher than 100fps.

When trying to configure frame rate at XSplit device configuration settings the values will be shown as

Default FPS “61” for example resolutions 2560X1080 and 2560X1440 the available frame rate values will be given from “61” to “100”.


We recommend either to choose RECentral 4 as your main software application or contact XSplit technical support for further assistance.


Please note that Cyberlink PowerDirector 15 for AVerMedia 4K doesn’t support import of 4K HDR HEVC (H.265) format video.

It’s possible that even though your platform fully meets our Live Gamer 4K (GC573) requirements due to motherboard’s PCI-E slot bandwidth planning frame drop will be generated when trying to record 4K P60 content under certain settings. In this case you can try followings:

1. Instead of using P010, RGB24 formats try NV12 or YUV (refer to RECentral 4 settings)

2. switch Live Gamer 4K (GC573) on another PCI-E slot

3. install the card on another PC environment.

It’s possible due to PCIe bandwidth allocated variously on each motherboard manufacturer. When you encounter frame drop issue (i.e. less than 60 fps), try to plug the capture card into another PCIe slot; or try NV12, YUY2 formats (refer to RECentral 4 settings).

If you need to select P010 to record HDR videos, please refer to the list of platforms that have been validated (see attachment).

You can download AVerMedia Gaming Utility (hyperlink); run it and tap ‘Change Resolution’ to choose a preferred resolution, and click ‘Switch’ to replace it.

Some resolutions are optional and you need to connect a pass-through monitor that supported this resolution; afterwards, you can choose it.

We recommend to use media playback software with hardware decoding (DXVA) support to play videos with high frame rate. For example  PotPlayer at the setup menu options select

Filter>>use built-in DXVA video decoder.

We highly recommend to use HDR supported TV or monitor with external HDR player to playback the video recorded in HDR format by GC573 Live Gamer 4K.

In order to playback the file on computer please download and install PotPlayer from also make sure to install madVR renderer from, and in PotPlayer settings, select Video -> Video rendering mode -> Madshi video player, after completing these steps you are ready to play HDR video.

The RECentral 4 recorded HEVC Main 10 HDR video footage can be uploaded to YouTube and played back directly in 2160p60 HDR format. In order to do so please remember to activate/ turn on HDR and WCG color setting.


To turn on HDR and WCG

  1. Select the Windows Start  button, then select Settings  > System  > Display .
  2. Turn on HDR and WCG.
  3. To view and change HDR and WCG settings, select HDR and WCG settings.


We would recommend you play the H.265(HEVC) video clip with Potplyaer or VLC.

First of all kindly note that by hardware design the GC573 Live Gamer 4K HDMI pass-thru can’t function if the streaming PC is turned off, this might cause an inconvenience especially if someone would like to use the gaming PC also when the streaming machine is turned off.

If you use gaming monitor with DisplayPort you may try following steps:


1. Connect your gaming graphic card to gaming monitor via DisplayPort and set it to “Primary display”


2. Connect the gaming graphic card to the capture card input port, via HDMI 2.0 cable

after this step, a new monitor entry appeared in Nvidia Control Panel, called “DisplayAdapter”

3. connect the capture card output port to the gaming monitor, via HDMI 2.0 cable.

4. after this step, the “DisplayAdapter” entry will be replaced by “AVT GC573”

5. uncheck the “[monitor brand/model] LCD” entry, and set the “AVT GC573” to “Primary display”


After that, hit Apply in Nvidia Control Panel dialog, and the gaming display will be automatically switched to HDMI input source.

If you turn off your streaming machine, the “[monitor brand/model] LCD” entry will automatically re-enable itself, and the gaming display will again switch automatically to DisplayPort input source.

A similar process will happen if you turn on your streaming machine after your gaming machine is already running, all automatically, with no user interaction required:

  • “[monitor brand/model] LCD” will be turned off in Nvidia Control Panel
  • “AVT GC573” will popup in displays list, qualified as “Primary display”
  • The gaming display will switch to HDMI input source

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.
