If you're facing a black screen issue on the Razer Central login page, try these steps to resolve it. First, update your graphics drivers to the latest version, as outdated drivers can cause display problems. Next, right-click on Razer Central and select "Run as Administrator" to ensure it has the necessary permissions. If the issue persists, uninstall both Razer Cortex and Razer Central, then reinstall the latest versions from the official Razer website. Additionally, clear the cache by deleting the "Razer" folder in C:\Users\[Your Username]\AppData\Local. Finally, check your antivirus or firewall settings, as they might be blocking the software, and consider temporarily disabling them. If none of these steps work, reaching out to Razer Support is recommended.

Additionally, check if your graphics drivers are up-to-date, as outdated drivers can sometimes cause display issues.

Hello I am having the same issue and I have attempted on a few occasions to reinstall and update with no joy. Would you be able to assist?

Thanks 

I have 2 monitors and a TV attached to my PC. The monitors are not compatible with HDR. The TV is and HDR was turned on in the System > Display > HDR settings. I turned it off and now Cortex is working. Even when the TV was off, apparently just having it selected was the problem.

Thank you for posting your solution!

Having the same back screen issue with cortex.

For months I have had this issue too, and today, I finally figured it out.  First, to be clear, the “issue” was launching Cortex would result in a brief view of the Cortex window, and then the window would go black, resulting in my closing the application by right clicking and closing the window in the taskbar.  The cause for this behavior is the HDR setting.  Today, I wanted to adjust my display settings a little, and turned-off HDR.  Low and behold, when I opened Cortex, it worked!  It did not go blank!  To verify, I turned the HDR setting back on, and guess what?  Yes, the blank window.  Hence, in my case, the Cortex app does not work with HDR turned-on.   FYI, I have all the Razer apps set to run as administrator.  I tried all the workarounds suggested other than reinstalling Windows.  Try turning off HDR, and see if that works for you as well.

1. uninstall
2. delete ‘C:\ProgramData\Razer’ folder
3. reinstall

that did it for me.

Hey @Nyagami ,

The installer sent to users before is earlier than the latest update. So, the current official version is the latest version. 

To fix this, could you clear the cache by following the steps below?

1. Exit Razer Cetral by right-clicking the Razer Central icon > Exit All Apps
2. Go to find this folder “WebAppCache” under “Razer Central” folder. You can copy and paste this directory %localappdata%\razer to fine them.
3. Clear all contents in “WebAppCache” folder.
4. Restart Razer Cebtral by launching any Razer apps. 

If this issue persists, please feel free to provide us with your logs via pm.
