Why does my Discord stream show a black screen when sharing a game?

Modern competitive games (such as Valorant, CS2, and Fortnite) run with elevated Administrator privileges. If Discord is running as a standard user process, Windows security restrictions prevent Discord from hooking into the game's DirectX graphics swapchain. Running Discord as Administrator resolves this immediately.

Why can my friends see my video but cannot hear my game sound on Discord?

Discord can only capture in-game audio when you stream a specific "Application" window, not your entire "Screen" or "Display". In the screen share prompt, select the "Applications" tab and click the game executable directly.

Does disabling hardware acceleration in Discord improve streaming performance?

For streaming, you should keep "Use hardware acceleration when available" enabled in Discord Voice & Video settings. This offloads video encoding to dedicated hardware engines on your GPU (NVIDIA NVENC or AMD AMF), preventing severe CPU stutter while gaming.

Why Black Screen Happens: Privilege Elevation & Hook Failure

When a game runs with anti-cheat (Valorant, CS2, Fortnite, Warzone), it runs with Windows Administrator privileges. If Discord is launched as a standard user process, Windows security blocks Discord from injecting its capture hook into the game's DirectX swapchain.

Solution 1: Run Discord as Administrator

Close Discord completely (right-click Discord in system tray → Quit). Right-click Discord shortcut → select Run as administrator. This grants capture hooks full access.

Solution 2: Toggle "Latest Technology" Capture

In Discord → Settings → Voice & Video → scroll to Screen Share → toggle OFF "Use our latest technology to capture your screen".
