Device connection keeps saying no input signal.

It’s suggested to check the following to identify if it is related to installation:  
 

1. New Firmware 
Access to GC513 download page. Download and upgrade to the latest firmware version :
Live Gamer Portable 2 PLUS - GC513 | AVerMedia

2. Mode Switch
GC513 has three modes, including PC mode, PC-Free mode, and Storage mode. Check if the Mode Switch is at a correct position 


3.  HDCP
If the video input source has HDCP (High-Bandwidth Digital Content Protection), check if the HDCP setting can be turned off from the video source in use, and then select GC513’s HDCP setting by AVerMedia RECentral application to be off or on based on the video source accordingly, as shown in the following chart: 

 
HDCP setting can be found in RECentral > Settings > HDCP Detection. 


4. VRR setting of xBox or PS5  
If the video source is xBox or PS5, connect the game console directly to the monitor. Turn off VRR setting. 


5. Video Sources & Resolution
Ensure the input source is with a standard HDMI 2.0 interface to connect to GC513. If the video source is other than a game console, there may be compatibility issue. If it is an iPhone, please use a Lightning Digital AV Adapter made by Apple. If it is an iPad, connect power adaptor to the Apple Lightning Digital AV Adapter during usage.

Further, check if the resolution and frame rate of the video source’s setting is supported by GC513:
• Supported Resolutions (Video input):2160p, 1080p, 1080i, 720p, 576p, 480p, 480i
 
6. USB & HDMI Cables
If GC513 device appears in Device Manager:
Check if swapping with a known good HDMI cable can fix an
issue like this.
 
If GC513 device does not appear in Device Manager:
> Connect to the other USB ports, or test on another computer
> Swap with a good USB cable
