Live Gamer EXTREME - GC550

(a) Please make sure you are using a native Intel, Renesas, or Fresco USB 3.0 chipset.
(To ensure the compatibility, check your computer's USB 3.0 whether it is a verified chipset made by Intel Native, Renesas, or Fresco.
Steps: Right-click My Computer --> Properties --> Device Manager --> Universal Serial Bus controllers --> Intel USB 3.0 extensible Host Controller)

(b) If you are using ASMedia USB 3.0 chipset, we recommend using Windows 8.1, or connect your LGX to a compatible USB 3.0 port (such as Intel’s).

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.
The images may have been enlarged or shrinked by the printer. If you need to output the cover files and print them in a shop or on another computer, please check the printer’s settings, and make sure the files are printed without scaling.

1.Device is not found
a.RECentral service couldn’t start or didn’t start properly. It’s possible that other applications installed on your computer is blocking RECentral service preventing RECentral to function normally.

→ We recommend you to check whether RECentral service has started up in Windows Task Manager

2. Device is occupied
a.This is a known issue in RECentral and GC550 driver 3.0.x.93 (there is a high chance to encounter this issue for frame rates other than 59.94 and 60).

→ We have detailed explanation on our website, if your video source is not 59.94 or 60fps, we advise you to install RECentral with Driver 3.0.x.90 (beta), we will provide complete solution in the upcoming version.

b.Either there is no audio output device installed on your PC (speaker or headphone), or they were not enabled in Volume Control Panel

→ Please confirm that your audio output devices functions properly (in Windows Volume Panel)
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.
