Are you experiencing the Hikvision NVR green screen issue? In this article, we will cover how to fix the problem and understand where it roots from.
Where And When The Hikvision NVR Green Screen Issue Appears
Users experience this problem while playing back footage or when the camera is on live view. It might occur randomly or be triggered by the change of HD to basic mode on the Hik-Connect app.
The reason behind this issue roots from a couple of factors. But it commonly happens because the NVR is unable to maintain the camera’s high settings.
Both your local network and your NVR might struggle to handle cameras at high resolution, especially multiple at once. For instance, you will run into issues if you are transmitting various cameras at 8MP full resolution simultaneously and your NVR can only handle 8MP.

When your recorder and network are unable to process and display the camera correctly, you will run into footage stuttering. A common kind of stuttering is the Hikvision NVR green screen issue.
Nevertheless, there are a couple of other reasons and factors at play that create this issue, including firmware, incorrect display settings, and hardware problems.
Fix Hikvision NVR Green Screen Issue
Below, we have outlined a few troubleshooting tips that could fix the green screen problem on your Hikvision camera. Take a look–
Video Settings
The first thing you should do is check your setting for the following:
- Resolution
- Bit Rate
- Frame Rate
To access the video settings, log in to your recorder’s interface using a web browser like Internet Explorer. The Hikvision NVR green screen issue can be fixed through video settings.
Start by lowering only the bit and frame rate. If you still encounter the problem, you can edit and lower the camera’s resolution. Refrain from lowering the frame rate below 15, and you can keep the cameras’ bit rate to 4Mbps.
After applying the settings, you will need to reboot your NVR before checking the Hik-Connect app. If you no longer see the Hikvision NVR green screen issue, it means your recorder cannot load all your cameras.
In this situation, you can leave the video settings as it is. However, if you want high resolution, frame rate, and bit rate, you need to upgrade your recorder. Other options include replacing your system or downgrading the cameras.
Downgrading The Cameras
Keeping your firmware updated to its latest version is good for avoiding bugs and having everything running smoothly. Nevertheless, you should take a step backward if you are facing the Hikvision NVR green screen issue after updating your firmware.
Remember that updates are meant to better the firmware, but it does not make it perfect. By downgrading back to your previous firmware, the issue should be gone.
You can update the firmware again once the bug has been fixed by Hikvision. Furthermore, make sure you downgrade to the correct firmware that used to work for you to avoid running into other issues.
Lack Of Compatibility With ONVIF Devices
A common reason behind the Hikvision NVR green screen issue is the inability of cameras to communicate with the recorder. This usually happens when users have third-party cameras.
These issues are typically fixed through firmware updates. Thus you should update your ONVIF devices to their latest software. To access the update files, check with your seller for new releases.
Moreover, it is crucial to keep your Hikvision NVR updated as well. Be cautious when downloading update files and ensure you have the correct one.
Downloading the incorrect file may cause additional issues to your device. Thus, always get your firmware updates directly from the manufacturer. If you still encounter the green screen after running the update, you should replace your camera or NVR, so they are compatible with each other.
Resetting Your Hikvision Camera
If you are experiencing the Hikvision NVR green screen issue in only one camera, you can reset it individually. To do so, you can physically find, press, and hold the camera’s reset button for 15 seconds.
You can also perform a factory reset through the camera’s interface. Once the camera is back online, check the app for green stuttering on your footage or live view.
Contact Hikvision
At this point, it’s a good idea to reach out to customer service to receive further assistance—whether that is Hikvision directly or a third-party seller.
Users facing the Hikvision NVR green screen issue reported that it was the cables on the motherboard that were lost. In this case, it is up to the manufacturer to replace or repair your issue.
Final Thoughts
It is common for Hikvision NVRs to experience a green screen issue, which various factors, such as outdated firmware, incorrect display settings, or hardware problems, can cause.
While this issue can be frustrating for users, it is generally fixable through troubleshooting and correcting any underlying issues. If you are experiencing a green screen issue with your Hikvision NVR, try updating the firmware, checking the display settings, and ensuring that all hardware is functioning properly.
If these steps do not resolve the issue, it may be necessary to seek assistance from Hikvision customer support or a qualified technician.
