How to Fix Discord Screen Share Black Screen/Not Working

The Discord screen share black screen issue occurs when the shared screen turns completely black, stopping others from seeing the content. This often happens because of a conflict between Discord’s “Use our latest technologies for screen sharing” feature and your system’s hardware. The most common cause is running Discord or the shared app in full-screen mode, which Discord struggles to handle.

Other factors include outdated graphics drivers, corrupted cache files, and hardware acceleration settings that interfere with Discord’s video processing.

Now that you know the causes let’s discuss the solutions.

1. Run with Admin Privileges 

Running Discord as an administrator ensures it has the necessary access to system resources. This is important when the app you’re sharing also has admin permissions, as different access levels can cause screen sharing to fail. Running both apps with the same permissions fixes this issue.

1. Press the Windows key and open the Start Menu.
2. Search for Discord.
3. Right-click on Discord and select ‘Run as administrator‘.

   

4. Ensure any other application is also run with admin rights by right-clicking its .exe file and choosing ‘Run as administrator‘.

2. Disable ‘Using Latest Technologies’ Option

When you disable the “Use our latest technologies for screen sharing” setting, it forces Discord to use older, more reliable screen-sharing methods. This option, while meant to improve performance, can cause conflicts with certain hardware, leading to the black screen issue. Turning it off helps Discord use a more compatible approach, minimizing display problems during screen sharing.

1. Open the Discord app.
2. Click the Settings icon at the bottom left.

   

3. Go to the Voice and Video section.
4. Under Video Diagnostics, turn off ‘Use our latest technologies for screen sharing’.

   

3. Disable Hardware Acceleration

If your GPU is struggling with Discord’s video processing, turning off hardware acceleration can help. This setting uses the GPU for better performance but can cause issues with screen sharing, especially if your graphics drivers are outdated. Turning it off makes Discord use the CPU instead, which often fixes black screen problems.

1. Open Discord and click the Gear icon to open settings.

   

2. Go to the “Advanced” tab and turn off “Hardware Acceleration”.

   

3. See if the issue continues.

4. Enable Reduced Motion

Simplifying Discord’s visuals by enabling “Reduced Motion” can help avoid black screen issues during screen sharing. This feature reduces animations, making Discord easier for your system to handle. By reducing the strain on your GPU, it helps prevent screen-sharing problems related to hardware limits or conflicts with the app’s graphics.

1. Open Discord and click the Gear icon for settings.

   

2. Go to “Accessibility”, uncheck “Sync with Computer”, and enable “Reduced Motion”.

   

3. Press CTRL + R to restart Discord.
4. Check if the issue persists.

5. Switch to Windowed/Borderless Mode

Sometimes, Discord has trouble capturing full-screen apps due to how they use system resources. Switching to windowed or borderless mode lets Discord access the screen content more easily. This change allows Discord to share the video output without problems, effectively fixing the black screen issue.

6. Disable Aero Theme

Turning off the Aero theme can fix Discord’s black screen issue by reducing the system’s graphical load. This is especially helpful for systems with limited graphics power.
