Black or white screen in WoW 1.12.1: the fix
Vanilla WoW Classic 1.12 · x5 realm · wowx5.ruThe game is running (you hear music or the cursor spins) but the screen is black or white — that is a display problem, not a server one. The cause is almost always Windows fullscreen optimization or a resolution your monitor does not support. Let's go step by step.
Step 1: disable fullscreen optimizations
This is the #1 cause on Windows 10/11:
1. Right-click WoW.exe → "Properties" → "Compatibility" tab. 2. Tick "Disable fullscreen optimizations". 3. Also enable compatibility mode for Windows XP (SP3).
Step 2: run in windowed mode
Windowed mode bypasses the fullscreen problem. Add a launch flag:
`` WoW.exe -windowed ``
Create a WoW.exe shortcut and append -windowed to the end of the "Target" line. When the game runs in a window, go to "Video" and pick a correct resolution, then switch back to fullscreen if you like.
Step 3: fix the resolution in Config.wtf
If the client remembers a resolution your monitor lacks, you get a black screen. Open WTF\Config.wtf in Notepad and set safe values:
`` SET gxResolution "1280x720" SET gxWindow "1" SET gxMaximize "0" ``
Save the file and launch the game. After logging in, set the resolution in the "Video" menu.
You can also delete Config.wtf entirely — it will be recreated. But then realmlist stored in Config.wtf resets and you will have to point to the server again.
Step 4: drivers and second monitor
- Update the GPU driver (NVIDIA/AMD/Intel).
- With two monitors, temporarily keep one as primary — WoW sometimes starts on the "wrong" screen.
- Try the
-openglflag (shortcutWoW.exe -opengl) if the black screen is DirectX-related.
FAQ
Why is WoW's screen black on launch but I can hear the music?
The game is running but not rendering. The usual culprit is Windows fullscreen optimization. Disable it in WoW.exe properties on the Compatibility tab and launch in windowed mode with the -windowed flag.
How do I fix a black screen via Config.wtf?
Open WTF/Config.wtf in Notepad and set SET gxResolution \"1280x720\" and SET gxWindow \"1\". Save and launch, then adjust the resolution in the Video menu.
What about dual monitors?
WoW sometimes starts on the second screen. Temporarily keep a single primary monitor or switch displays, then set the resolution in-game.
