First check whether only Rainbow Six Siege is black or the whole monitor loses its picture. If Windows remains visible, restart the game, update the graphics driver, verify the game files, and test with overlays closed. If the monitor also loses signal in other apps, check the display cable and graphics hardware instead. Keep audio, error, and display details for Ubisoft Support if the game alone stays black.
Press the Windows key or switch to another app. If Windows is visible and only the game is black, continue with the game checks. If the monitor reports no signal or other apps also disappear, check the display connection or PC instead.

Restart and update
Close Rainbow Six Siege and its launcher, restart Windows, and install current game, launcher, Windows, and graphics-driver updates. Use the driver from the graphics-card or PC manufacturer.
3
Verify the game files
Use Verify files in Ubisoft Connect, or in Steam open Library > Rainbow Six Siege > Properties > Installed Files > Verify integrity of game files. Let the launcher replace damaged files before reopening the game.
Close Discord, Steam, Ubisoft, recording, FPS-counter, and graphics-filter overlays for one launch. These tools draw over the game and can help identify a display conflict when removed from the test.
5
Check the display path
Reconnect the display cable firmly and, if available, test another cable or monitor input. Skip this step when Windows and every other game display normally; that result points back to Rainbow Six Siege.
6
Report the exact result
If only Rainbow Six Siege remains black, tell Ubisoft whether audio continues, whether the menu ever appears, which launcher and monitor are used, and which GPU and driver are installed.
If the game works after overlays are closed, enable them one at a time to find the conflict and keep that overlay off for the game.
If the whole monitor loses signal under load in more than one game, stop repeated reinstalls and have the cable, power, temperature, and graphics hardware checked.
