In Falsus demo has music but no picture — what do I do?

Press Alt+Enter immediately. The demo is alive; the display mode is wrong. If the picture returns in windowed mode, set borderless/windowed in graphics settings so the next launch sticks.

In Falsus won't launch — is it the same fix?

A launch that ends on a black screen with audio is usually the same fullscreen issue — start with Alt+Enter. A total hang with no audio may need Steam file verification or a driver update instead.

In Falsus Black Screen Fix (Demo): Alt+Enter First, Then These 5 Steps

Q: Why is In Falsus showing a black screen?

Most often the game is running but fullscreen handoff failed — you hear music but see nothing. Press Alt+Enter to switch to windowed mode. If that fails, update GPU drivers, disconnect extra monitors, verify Steam files, or check that your PC meets the DirectX 11 minimum specs.

In Falsus demo won't launch or shows a black screen with music? Press Alt+Enter first — then work through GPU drivers, multi-monitor, Steam file verification and minimum specs in order.

You launch the In Falsus demo, the music starts playing — and the screen stays black. First move: press Alt + Enter. In most reports the game is already running; only the fullscreen handoff failed. This guide walks through every fix in order when Alt+Enter alone is not enough.

Fix 1: Press Alt + Enter (works for most people)

If you hear music but see nothing, the game is running — the fullscreen handoff failed. Press Alt + Enter to toggle between fullscreen and windowed mode. This is the fix lowiro themselves have pointed players to, and it resolves the majority of black-screen reports.

If the picture comes back in windowed mode, set the game to borderless / windowed in the graphics settings so it doesn't happen on the next launch.

Fix 2: Update your GPU drivers

In Falsus runs on DirectX 11. An outdated graphics driver is the usual cause when Alt+Enter doesn't help:

NVIDIA: GeForce Experience → Drivers → Download, or nvidia.com/drivers
AMD: AMD Software Adrenalin → Check for updates
Intel: Intel Driver & Support Assistant

Restart after installing, then launch the demo again.

Fix 3: Disconnect the second monitor

Multi-monitor setups confuse fullscreen games more often than you'd think — the game can render fullscreen on a display that's off or asleep. Unplug (or disable with Win + P) every display except your main one, launch the game, and re-enable them afterwards.

Related: if Windows display scaling is above 100%, try setting the game's executable to override high-DPI scaling (right-click the exe → Properties → Compatibility → Change high DPI settings).

Fix 4: Verify the game files on Steam

A partially downloaded or corrupted install shows exactly these symptoms:

Right-click In Falsus Demo in your Steam library
Properties → Installed Files → Verify integrity of game files
Let Steam re-download anything broken, then relaunch

Fix 5: Check the minimum specs

The demo needs a 64-bit Windows 10 or newer, 8 GB RAM and a GPU with DirectX 11 support. Older machines that fail one of these tend to produce a black screen with audio rather than a clean error message. There is no macOS build.

Fix 6: Linux, Steam Deck, and Proton

If you're on Linux or Steam Deck, black screens and missing intro images are common on stock Proton. Community fixes:

Install GE-Proton 10-32 or 11-1 via ProtonUp-Qt and force it in game Properties → Compatibility
Lower your audio output sample rate to 24-bit / 96 kHz (Windows-style audio settings in Desktop Mode)
If video still fails, try Proton-CachyOS or install Windows Media Foundation via protontricks

Full Deck setup (gyro layouts, touchpad Field notes, performance): see the Steam Deck guide. Hard crash with no audio? Read demo won't launch instead.

Still black?

Close overlays (Discord, MSI Afterburner, GeForce overlay) — rhythm games and injection overlays don't mix.
Report it: the Steam discussion board has an active thread on black-screen launches, and lowiro has been shipping demo patches (the demo is already on v0.3.x).

FAQ

Why is In Falsus showing a black screen? Usually a failed fullscreen switch — Alt+Enter fixes it. Driver issues, extra monitors, corrupted files, and under-spec hardware are the next suspects.

Music plays but the screen is black — what now? Alt+Enter, then borderless/windowed mode in settings. That combination covers most demo players.

Is a black screen the same as the game not launching? Black screen with audio = almost always display mode. No audio at all = try file verification and drivers first.
