Castlevania: Belmont's Curse Demo Black Screen Fixes

How to Fix the Demo’s Black Screen at Startup

Stuck staring at the Castlevania: Belmont's Curse demo black screen instead of reaching the menu? Start by lowering your display’s refresh rate to 120 Hz or below, then try 60 Hz with a single display if the screen stays black. The Castlevania: Belmont's Curse demo black screen also has working fixes involving VSync, AMD Enhanced Sync, and resetting the PLAYERPREFS.sav file, giving you several targeted changes to try before reinstalling.

The fixes below address the PC demo’s startup problem. Work through them in order, closing the game before each change and relaunching afterward. Change one setting at a time so you can tell which adjustment gets you into the menu.

Fix	What to change	Result achieved
Lower display refresh rate	Set the monitor to 120 Hz or below	Resolved startup black screens on a 240 Hz desktop setup
Simplify the display setup	Use one display at 60 Hz	Allowed the demo to start on a dual-monitor setup
Adjust synchronization	Enable VSync; on AMD, disable Enhanced Sync	Resolved the black screen on affected configurations
Reset saved preferences	Reset PLAYERPREFS.sav after backing it up	Restored startup for affected installations

Start with display settings before touching saved files. Refresh rate and synchronization changes are reversible, and they directly match the startup behavior described here.

If the demo worked previously but now opens to black, keep the preferences reset in mind. You can use that fix without clearing the entire game folder.

Lower Your Monitor’s Refresh Rate

A high-refresh monitor is a useful place to start troubleshooting the Castlevania: Belmont's Curse demo black screen. Dropping a desktop display from 240 Hz to 120 Hz resolved the problem on one affected setup.

You do not need to match that exact hardware configuration to try the adjustment. Use your display’s refresh-rate controls to select 120 Hz or a lower supported option, then launch the demo again.

Try 120 Hz, Then 60 Hz

Follow this sequence:

1. Close the demo.
2. Set the display you use for the game to 120 Hz or below.
3. Launch the demo and check whether the menu appears.
4. If the screen remains black, close it and try 60 Hz.
5. If you use multiple monitors, test with only the main display active.

The single-display test matters because another successful workaround combined two changes: disabling the second monitor and setting the main monitor to 60 Hz. If lowering refresh rate alone does nothing, try that combination.

Display situation	Adjustment to try	What to check afterward
Desktop monitor running at 240 Hz	Lower it to 120 Hz	Whether the demo reaches its menu
Black screen continues at 120 Hz	Lower it to 60 Hz	Whether the lower refresh setting allows startup
Two monitors connected	Test with one active display at 60 Hz	Whether the simplified setup launches successfully
ROG Ally	Select 120 Hz or below through its display controls	Whether the game opens normally

Keep Refresh Rate and Frame Rate Separate

Your monitor’s refresh rate and the game’s frame-rate cap are different settings. Changing the cap inside the game does not replace lowering the display’s refresh rate outside it.

That distinction matters when the menu never appears: you need an adjustment you can make before launching. Start with the display itself, then revisit the game’s graphics options once you can see them.

After a successful launch, close and reopen the demo with the same display configuration. Check that startup works again before restoring other settings. This keeps a successful test from getting lost among several simultaneous changes.

Enable VSync and Check AMD Enhanced Sync

If lowering refresh rate does not resolve the Castlevania: Belmont's Curse demo black screen, move to synchronization settings.

Enabling VSync resolved the startup issue on another affected setup. For an AMD configuration, the successful combination was Enhanced Sync off and vertical refresh on.

These settings deserve a separate test from refresh rate. Lowering the monitor’s refresh rate did not work for every affected installation, so do not stop troubleshooting just because the first display adjustment fails.

Setting	Adjustment to try	Scope
VSync	Enable it	Resolved the demo’s startup black screen on an affected setup
AMD Enhanced Sync	Disable it	Part of a successful AMD workaround
AMD vertical refresh setting	Enable it	Used alongside disabling Enhanced Sync
In-game frame-rate cap	Keep separate from display refresh troubleshooting	The game offers caps from 30 fps through unlimited

Apply the AMD Changes Together

If your AMD graphics settings have Enhanced Sync enabled, turn it off and enable vertical refresh, then relaunch the demo.

Record the original settings before changing them. That gives you a clear way back if the adjustment does not help, especially if you are using graphics controls that also affect other games.

If you can reach the game’s options after a successful launch, VSync is also available there. The PC version includes fullscreen, borderless, and windowed modes, resolution selection, and a frame-rate cap.

Keep the test focused on synchronization. Changing anti-aliasing, brightness, and several display options together makes it harder to identify what fixed startup.

Check Startup Again After Changing Settings

Getting past the black screen once is useful, but the next launch matters too. Close the demo normally and open it again before making further adjustments.

If you reach the menu consistently, keep that working configuration while you play. If startup breaks again after changing settings, return to the configuration that worked or move on to resetting saved preferences.

Reset PLAYERPREFS.sav Without Clearing the Whole Folder

Resetting saved preferences is another working fix for the Castlevania: Belmont's Curse demo black screen. The specific file identified in the successful workaround is:

Image: Steam / KONAMI

C:\Users\[username]\AppData\LocalLow\KONAMI\Castlevania Belmont's Curse\PLAYERPREFS.sav

Replace [username] with your Windows account name. If your AppData folder is on another drive, use that drive instead of C:.

Back up the folder before changing anything. Although a broader folder deletion also resolved the problem, resetting the single preferences file is the more focused adjustment.

Item	Location or action
Game folder	C:\Users\[username]\AppData\LocalLow\KONAMI\Castlevania Belmont's Curse\
File involved in the workaround	PLAYERPREFS.sav
Backup step	Copy the folder somewhere safe before making changes
Targeted reset	Move PLAYERPREFS.sav into your backup location
Next check	Relaunch the demo and check whether the menu appears

Make a Reversible Preferences Reset

Use this approach:

1. Close the demo.
2. Open the game folder at the path above.
3. Copy the folder to a separate backup location.
4. Move PLAYERPREFS.sav out of the original folder and into your backup.
5. Launch the demo again.

The successful fix involved deleting this individual file. Moving it aside lets you test its removal while keeping the original available.

Do not clear neighboring files just because they sit in the same directory. Start with the exact file associated with the working fix.

Keep Your Backup Until Startup Is Reliable

If the demo launches afterward, check its settings before playing. Then close and reopen it to check the result again.

Keep your backup while testing. If you need to undo the change, close the game before restoring the original file. Preserve any newly created version separately rather than overwriting files without a copy.

For a Castlevania: Belmont's Curse demo black screen that returns after an earlier successful session, this preferences reset gives you a targeted alternative to repeatedly changing monitor settings.

Handle ROG Ally and Steam Deck Problems Separately

Handheld PCs need a little extra care because a startup black screen and uneven gameplay performance are different problems.

On ROG Ally, setting the display to 120 Hz or below resolved the black screen. Use the quick access menu or Armoury Crate display controls to make that adjustment before launching.

Once running, the full game delivered approximately 65–110 fps in tested areas on a ROG Ally Z1 Extreme at 25 W. Those results apply to that hardware, power setting, and full-game test. Use them as context for what happened after the startup fix, rather than as a promise for every demo session.

Steam Deck Hitching Needs a Different Decision

Steam Deck’s documented problem was inconsistent performance, including hitching at 30 or 40 fps. Testing across multiple Proton versions, including Proton Experimental and GE versions, did not resolve that behavior.

If your Steam Deck reaches gameplay but stutters, you are dealing with a performance issue rather than the same symptom as the Castlevania: Belmont's Curse demo black screen.

Avoid cycling through compatibility settings indefinitely to solve that specific hitching problem. Wait for performance patches if the uneven frame delivery makes the game uncomfortable to play.

If the Demo Still Opens to Black

Close and relaunch it once; a restart resolved the issue on an affected installation. If that does not help, check that you have actually tested the distinct fixes:

• A display refresh rate of 120 Hz or below.
• One active display at 60 Hz.
• VSync enabled.
• Enhanced Sync disabled with vertical refresh enabled on AMD.
• A backed-up reset of PLAYERPREFS.sav.

Keep a short record of which changes you tried and what happened. Include your graphics hardware, display setup, and whether the demo ever reached its menu when describing the problem through the developer’s channels.

FAQ

What should I try first for the Castlevania: Belmont's Curse demo black screen?

Lower your display’s refresh rate to 120 Hz or below, then relaunch the demo. If that fails, test 60 Hz with only one display active. Both configurations resolved startup problems on affected setups.

Does enabling VSync fix the demo’s black screen?

Enabling VSync resolved the problem on an affected setup. On AMD hardware, another successful combination was disabling Enhanced Sync and enabling vertical refresh. Test those settings separately from your monitor refresh-rate changes.

Which file should I reset if the demo stops launching?

Back up the game folder, then move aside PLAYERPREFS.sav from AppData\LocalLow\KONAMI\Castlevania Belmont's Curse. Resetting that individual file restored startup without requiring the entire folder to be cleared.

Does the ROG Ally black screen fix also solve Steam Deck stuttering?

The ROG Ally workaround addresses startup by setting the display to 120 Hz or below. Steam Deck hitching persisted during separate performance testing, including at 30 and 40 fps. Apply the refresh-rate fix to a black screen; wait for performance improvements if your problem is uneven gameplay.
