Hello,
I recently found a working hotfix for this issue.
Step 1) Open your WoW directory
Step 2) Find the WTF folder
Step 3) Open "Config"
Step 4) Replace everything inside that folder with this
" SET hwDetect "0"
SET gxColorBits "24"
SET gxDepthBits "24"
SET gxResolution "1920x1080"
SET gxRefresh "60"

This has helped 5 people so far so if this doesn't work make sure your realmlist.wtf file says the correct login server and if that doesn't work come back and we will try something else okay?
