The firmware version number often contains information that indicates when it was released. For example, "V3.00.52.220921," the information can be interpreted as follows:
- "V3.00.52" comprises the main version number and subversion number.
- "220921" represents the release date, presented as YYMMDD (Year, Month, Day).
Based on this interpretation, the firmware version "V3.00.52.220921" would suggest that it was released on September 21, 2022. If it's required to download the latest firmware, please go to

What does 1920*1080P@30HZ mean?
If it shows 1920*1080P@30HZ on GUI, probably it's failed to detect the HDMI signal. Take the following steps if there is a failure to detect an HDMI signal. Ensuring that the HDMI cable is properly connected and meets the necessary requirements, as well as checking and adjusting the output resolution of the HDMI signal, can often resolve detection issues.
If the HDMI detection issue persists despite checking the cable and resolution, it could be related to the Extended Display Identification Data (EDID). The EDID is information provided by a display to the source device, and issues with EDID communication can result in detection failures. In such cases, troubleshooting the EDID communication and potentially getting the log when you're trying to connect this HDMI may be helpful for us to help you resolve the detection problem.
What could be the reason for the failure to detect an HDMI signal from a Rapberry PI?
If you're encountering issues with detecting an HDMI signal from a Raspberry Pi, it's advisable to consider adjusting the audio input from HDMI to Line-in. The reason for this recommendation lies in the dynamic nature of audio on Raspberry Pi devices. When the audio fluctuates, if the encoder continually uses HDMI input for audio, it will repeatedly attempt to detect the HDMI signal whenever changes occur. By switching to Line-in for the audio input, this perpetual detection process is avoided, offering a more stable signal. This approach differs from connecting the Raspberry Pi to a TV, where audio and video are simply displayed. For the encoder, both the video and audio need to be encoded together with the HDMI signal, and this adjustment is crucial for optimal performance.
How can we determine which firmware version we should download?
Usually, you can determine the appropriate firmware version based on the serial number. If the serial number starts with HDMIGKE202
3, download it from
GK72 MS7 Encoder series. If it starts with HDMIGKE202
2, download from
GK72 ITE Encoder series. If it's displaying
TV-MIX in the device manager, download from
TV30 MS7 Codec Series or
SS50 MS7 Codec Series. If you still have no idea which firmware version you should download, you can chat with our online chatbot and it will guide you on how to download the correct firmware related to your encoder or codec.
