* Note: The black area in this raw screenshot represents physical dead space (where you do not have a monitor). The game seamlessly conforms to your actual screens.
Keep your world map, bags, and character sheet open on your second screen without cluttering your game view. They stay open even while you're moving around the world.
Play on your main screen with a perfectly centered character and combat HUD, exactly how you're used to playing. No weird camera stretching or misplaced action bars.
Engineered for Dual-Screen Gameplay
Designed specifically for WoW players running dual monitors, whether matching screens or asymmetrical portrait + landscape.
1:1 Aspect Ratio Lock
Mathematically isolates 3D viewport coordinates to your primary gaming monitor. Prevents the severe horizontal stretching, camera distortion, and bezel-splitting caused by raw desktop spanning.
Persistent Offhand Monitor
Turns your second display into an expansive Offhand Monitor. Keep your World Map, bags, character sheet, and quest log open simultaneously without frames fighting for screen space or closing when you walk.
1-Click Auto-Configuration
Type /offhand in-game. The built-in setup wizard inspects your display resolution, detects primary monitor orientation, and configures viewport anchors automatically in seconds.
Combat Safe & Taint Free
Built strictly within Blizzard's secure execution environment. Layout transitions and frame repositioning are deferred safely during combat, ensuring zero Lua taints or UI errors.
Mix & Match Monitors
Got a 4K main screen and a 1080p vertical monitor on the side? No problem. Offhand handles asymmetrical layouts, mixed resolutions, and different refresh rates naturally.
Lightweight Windows Companion
Includes an optional, open-source Windows companion app (Offhand.exe) to borderless-span your game window in a single click without complicated GPU surround setups.
Your setup, one click away
Span WoW across your monitors, restore a single window, or let the Companion span automatically when the game launches. Check your connection and recent activity from one compact Windows app.
Keep it nearby in the system tray and use your chosen hotkey whenever you need to span.
Get Started in 3 Simple Steps
No complex configuration required. Get up and running in under two minutes.
Install the Addon
Install Offhand via the CurseForge App, WowUp, or manually extract the Offhand folder into your World of Warcraft\_classic_era_\Interface\AddOns\ directory.
Span Your Game Window
Put WoW in Windowed mode. Extract the Offhand-Companion.zip folder, launch the Offhand Companion app inside, and hit Span Now to stretch the game across your monitors without the ugly Windows borders.
Note: Windows SmartScreen may flag the app as unrecognized on your first launch. This is normal for open-source tools. Click More info → Run anyway.
No App? Just grab the edges of your WoW window and manually stretch it across both screens yourself.
Auto-Configure In-Game
Type /oh in chat and run the quick setup wizard to align your bezels and scale your UI. You're ready to play!
Frequently Asked Questions
Direct answers to common questions about safety, compatibility, and setup.
How do I set World of Warcraft into Windowed mode?
Offhand requires World of Warcraft to run in standard Windowed mode so the window can span freely across your dual displays. You can set this in three ways:
- In-Game Menu: Press Esc → click Options (or System in Classic) → under Graphics, set Display Mode to Windowed → click Apply.
- Keyboard Shortcut: While World of Warcraft is active and focused, press Alt + Enter to immediately toggle between fullscreen and windowed mode.
-
Config.wtf File: If you cannot open the game, open your
WTF\Config.wtffile in Notepad and add or edit the line:SET gxWindow "1".
Does spanning World of Warcraft stretch or distort the 3D camera?
No. Offhand uses native Blizzard viewport coordinate APIs to constrain 3D camera rendering strictly to your primary monitor's pixel bounds. Your camera aspect ratio and field of view remain native 1:1, completely eliminating horizontal fisheye distortion.
Is the desktop companion app required?
No. The companion app (Offhand.exe) is an optional convenience tool to borderless-span your game window in one click. You can also use GPU driver spanning (NVIDIA Surround, AMD Eyefinity) or utilities like Borderless Gaming and DisplayFusion.
Does it work with different monitor sizes and vertical screens?
Yes. Offhand is specifically engineered for asymmetrical multi-monitor setups, including vertical portrait monitors alongside ultrawide or standard landscape gaming monitors, with independent refresh rate handling.
Is Offhand safe and compliant with Blizzard's Terms of Service?
Yes. The in-game addon just uses standard Blizzard UI APIs. The companion app is open source and only resizes your Windows desktop window - it doesn't touch the game's memory, alter files, or automate gameplay.
Which versions of World of Warcraft are supported?
Offhand is built and tested for World of Warcraft Classic Era (1.15.x), Hardcore, and 20th Anniversary Classic realms, with underlying architecture compatible with modern Retail.
