Befor the update, Classic WoW, work fine.
After the update (Classic TBC) i see a Black screen (can hear the music, and sound).
The computer is little bit older… but like i said it worked in Classic, with no problems.
Any sugestions.

I get a list of offline realms.
Try updating your graphics drivers.
try pressing alt+enter to see if it will go out full screen then change resolution.
I have the same problem but my screen is not black, i just can see trough the game window, i have the wow cursor and the music but nothing to see 
Funny thing is: i have an old lich king client that work perfectly fine. (i just tried it)
So yeah classic worked fine, lich king client work fine but BC have a problem…
Did they do something to the graphics or anything that would explain why my pc can’t run it ?

I believe I saw online that they’ve updated the client/engine to the same one that was used in BFA with tweaks for better optimizations.
Either the files scuffed, blizz is still working on them. Or black screens are usually due to GPU drivers or direct x out of date. Every time I’ve had it in other games (sound/mouse works but black screen) it’s always been direct x. Never had it with wow though.
Well… my graphics is a Intel HD 3000…
Things i’ve done:
- Upgrade Windows 10 to 21H1;
- Unninstall and delete WoW Classic directories;
- Install WoW Classic TBC, again from scratch.
- Add the cmd -d3d11legacy in Battle.net
Now i can see the screen and servers list 
Thx for the inputs M8s.
Best regards

This is what i did, and it worked instantly.
click the options wheel on launcher - go to game setting and check “Additional command line arguments”
Write “-d3d11”. should do the trick

I did all that, still no changes… It’s not really a black screen: i succesfully made it launch in windowed mode and the window just stays white and it’s very laggy (when i try to close it for example) and i still can hear music and see the cursor
Edit : i have a Intel HD 4000, drivers are up to date as is windows10
Usually goes white and laggy when it crashes. Update GPU drivers/dirext x drivers/windows update and reinstall the game. Literally can’t think of anything else that would mess wow up.
Yeah i just did all that…
Make sure you guys edit the command line for the right game version.
“World of warcraft classic”
because Burning crusade (classic beta) is above it, and you may have edited that one.
the way I got it working is the -d3d11legacy, but wouldn’t work with -d3d11. Try adding the legacy bit after the 1 without space. Hope it helps

Thanks… That was it for me, I was starting to lose hope. Windows updated to 20h1, classic and classic era reinstalled. The change was adding the legacy to the -d3d11.
I have the same problem please help me. How do you “add” cmd-d3d11legacy in battlenet? Can someone explain?
Hey there, initially I had the same issue: Could see the mouse cursor and hear the music but didn’t show up the log-in screen. Tried to add the -Windowed command which made the window white.
What helped me was to start WoW Classic manually and set compatibility to Windows 7
Win7 compatibility is essentially the same as setting the -d3d11legacy command-line parameter.
This worked for me as well. I imagine some setting requires by default full DX12 (i.e. Shader Model 5.1), which is what breaks the client on older GPUs
Go to you game setting in Battle net app. I haven’t got it in front of me, but click on World of Warcraft classic and add a command line. -d3d11legacy with the dash at the beginning too
Or
Read another thread. Type in to search TBC black screen and there will be step by step process from bliz
Well the legacy command line do not work for me i tried the other way and set compatibility to windows 7 but it doesn’t work either
edit : BC is now running. Thx all of you for your help and input ! See you in gameeeeee
Edit n2: what did the trick for me is running it under windows7 with dx11 BUT i had to go and manually get a pluggin for my graphic card as well (windows was considering it as up to date but it was fake news)
