To perform the test, click on the “Settings” icon on the upper left side, select the Live Gamer ULTRA and click on the “Performance” tab. Once there click on “Start” (it will take about 10 secs).
The performance test will let you know what resolutions and at which frame rate you can record. This table will depend on the pixel format you will like to record in, at the drop-down menu you can choose and see how these formats will affect your ability to record on which resolution and at which frame rate.
• YUV2: Medium quality, medium CPU usage
• NV12: Optimized performance, low quality, lowest latency, lowest CPU usage (default)
• RGB24: Highest quality, low latency, high CPU usage
• P010: HDR recording pixel format, high CPU usage (Only available for 1080p)
STEP 1: Make sure to connect GC553 LGU with its USB Type-C cable to USB 3.1 Gen 1 (also called USB 3.0) port. We strongly recommend to use native Intel USB host controller.
STEP 2: Check Device Manager, GC553 LGU should be displayed under Sound, video and game controllers and Cameras.
STEP 3: To confirm what USB chipset you are plugging the LGU to download a free software called “USB Device Tree Viewer”. This will allow you to see which USB host you are connecting it to. In order to get the best experience, make sure it’s an Intel one as other hosts may have a high probability of having unstable speeds.
STEP 4: After installing RECentral 4 Live Gamer Ultra (GC553) will be detected as shown on following picture.
Due to stability issues and to ensure smooth and solid performance we highly recommend to run Live Gamer Ultra on Intel motherboard and plug it on native Intel USB host controller or Intel Gen 1 host.
You can also save your recordings on a USB drive and connect it directly to your 4K HDR TV (if your TV supports it) or to an HDR player connected to your TV video HDMI 2.0.
Please note that each 4K HDR monitor or TV panel will have different luminosity parameters, therefore you might experience a slightly different color representation while playing back your 4K HDR recorded video files.
If you would like to playback your 4K HDR files on your computer, we strongly suggest using “PotPlayer” and download “madVR” codec files. While playing the file on PotPlayer right click on the screen, select Video > Video Renderer > Madshi Video Renderer, this will allow you to properly playback HDR video format.
This issue can be fixed by adjusting your motherboard’s BIOS (CPU CLOCK) settings.
Enter BIOS (refer to below screenshot), select “Advanced” mode, then “Al Tweaker” page at CPU Core Ratio set “Sync All Cores”.
When setup Live Gamer Ultra with PS4 Pro make sure to turn off/disable HDCP at PS4 console settings just like it’s shown on following video tutorial and leave RECentral 4 HDCP detection setting ON.
In order to ensure that the audio and video are in full sync please enter XSplit settings, select device and right click on the mouse, under “Offset (ms)” you can adjust A/V sync.
Please make sure to set “WaveOut” audio renderer to solve this issue, for settings refer to screenshot below:
At OBS you can set the audio delay shift value to ensure that you get fully synchronized recorded file.
In addition, if you set the output waveout, you do not need to change any settings, the recorded file will be synchronized.
1. OBS setting “Output desktop audio (waveout)” => Audio select “Stream Engine”
2. OBS setting “capture audio only” => Audio select “HDMI (Live Gamer Ultra-Audio)”.
*If Stream Engine is selected, the file's audio will be faster, in this case if you shift the audio back for 100ms the recorded footage will be synchronized.
Please adjust OBS settings:
1. Open OBS and click on “Mixer” gear icon.
2. Under “Advanced Audio Properties”>>”Video Capture device”>>“Sync offset”option add value“200”(ms)
Please make sure to use HDMI 2.0 cables only for connecting PS4 PRO and the 4K TV to the Live Gamer Ultra capture card and confirm whether does the 4K TV HDMI IN port support
HDMI 2.0 specification. In general we recommend to connect Live Gamer Ultra to HDMI-1 port on your 4K TV.
Note that some TVs will need to adjust further settings:
Press the Menu button your TV remote.
Scroll down and choose options.
Select HDMI Input Mode.
Set the input mode to HDMI 2.0
Please check following points in order to avoid issues with 4K input (console, PC, media player) and output (4K HDR TV):
STEP 1: Make sure to connect input source (HDMI IN) and 4K TV (HDMI OUT) by HDMI 2.0 (premium high speed HDMI) cables.
STEP 2: Connect 4K display. Otherwise the output will be limited to 1080p (full HD) resolution. Note: if you want to use HDR recording function you need to make sure that your 4K TV has HDR support as well.
STEP 3: Make sure the HDMI port connected to Live Gamer Ultra (GC553) is a HDMI 2.0 port on the 4K TV.
Some 4K TVs may only support 4K video via a DisplayPort cable and may have HDMI ports that are version 1.4, that only supports 4K at 30 fps.
If the Live Gamer Ultra is connected to a HDMI 1.4 port, then the consoles will limit resolution to 1080p60.
STEP 4: Make sure that the TV connected to Live Gamer Ultra has 4K resolution activated.
Some TV manufacturers have placed the option to enable 4K input in the settings.
This might result that the Xbox One X or PlayStation Pro connected to the Live Gamer Ultra fail to output 4K resolution.
The solution is to check the User Manual of your TV to ensure that 4K is enabled for the HDMI port you connect Live Gamer Ultra to.
Please note that these type of issues most of the time can be traced back to the HDMI cable that is used for the connection.
It’s possible that the HDMI cable is broken or not support the input resolution, a long cable might result weak signal too.
In order to fix such issues please try to
1. Switch to another HDMI cable
2. Use Premium High Speed HDMI certified (HDMI 2.0) cables
3. Try a shorter HDMI cable

For HDR experience, make sure your TV supports the HDR10 media profile. Check your TV manual to verify. Some manufacturers may not mention HDR10—look for support of BT2020 and HDR, or some of the names in the following list. (Also, there are two HDR formats: Dolby Vision and HDR10. Your TV can support both, but it must at least support HDR10.)
Names for HDR10: HDR Premium, High Dynamic Range, HDR, UHD Color, Ultra HD Premium, Ultra HD deep color.
