The short answer
KONAMI identifies a launch issue when V-Sync is off and FPS is unlimited. Apply available updates, including the original review’s 1.1.3 fix baseline. If it persists, temporarily select a supported refresh rate below 60 Hz in Windows, enable V-Sync in the game, exit and restore the original refresh rate. Do not invent an unsupported display mode.

Step 1|Use the official V-Sync workaround
The temporary Windows change makes the game’s video menu accessible on affected systems.
Time: About 10 minutes · Risk: low
- Apply available Steam updates; the original review’s fix baseline is version 1.1.3 or later.
- If it still will not launch, record the current refresh rate. In Windows Settings → System → Display → Advanced display, select a supported rate below 60 Hz.
- Launch the game, open Settings → Video from the title screen, enable V-Sync and exit the game.
- Restore the original Windows refresh rate, then compare launch again.
Some monitors do not offer a rate below 60 Hz. Do not force a custom mode; use KONAMI support if the workaround is unavailable or does not help.
Results that did not fix the problem help the next reader too.
Step 2|Check Windows 11 and the full hardware baseline
The original store review lists Windows 11 for both minimum and recommended configurations.
Time: About 3 minutes · Risk: low
- Press Windows+R, run winver and record the Windows version.
- Open Task Manager → Performance → GPU and compare the exact model with GTX 1650.
- Confirm at least 16 GB RAM and 10 GB of available storage.
Results that did not fix the problem help the next reader too.
Step 3|Compare driver, files and overlays
Test after each change to retain a useful result.
Time: About 15 minutes · Risk: low
- Check an applicable current official driver through NVIDIA App, AMD Software: Adrenalin Edition or Intel’s website, then restart after installation.
- Steam Library → right-click the game → Properties → Installed Files → Verify integrity of game files.
- Temporarily disable Discord/Steam overlays and recording/FPS tools for comparison; restore them individually if they make no difference.
Results that did not fix the problem help the next reader too.
Step 4|Compare Steam Input with one controller
An extra translation layer may affect the result; controller support alone does not identify the cause.
Time: About 5 minutes · Risk: low
- Connect one controller by USB.
- In Steam Library → Properties → Controller, record the current Steam Input override and compare the alternative.
- Close other controller remappers before testing.
See the linked Steam Input guide for the per-game comparison and restoration steps.

Step 5|Check the edition and separate gallery app
The original review describes a separate gallery with over 100 artworks and a music player.
Time: About 3 minutes · Risk: low
- Look for the digital sound/art gallery separately in the Steam Library.
- Compare your purchase with the three Midnight Edition items described in the original review: Trevor-style costume, Sypha-style costume and the family-portrait relic. These are descriptive translations, not newly verified English menu labels.
- The Alucard-style costume is the preorder bonus; do not assume a later purchase includes it.
Use the publisher’s release instructions for in-game delivery rather than guessing an unverified claim location.

Avoid
- Do not use unofficial modifications to bypass hardware or OS requirements.
- Compare the edition and separate extras before buying the same content twice.
Important cautions
- The original October 16 review described further black-screen work in progress. Check later official announcements instead of assuming 1.1.3 is the newest patch.
- KONAMI’s current issue notice also describes some Steam Deck UI appearing outside the screen.
FAQ
Why does a high-refresh-rate monitor show a black screen?
KONAMI identifies the combination of V-Sync off and unlimited FPS. Apply updates first, then use the supported below-60-Hz workaround, enable V-Sync, exit and restore the original rate. Not every black screen proves this cause.
Is Windows 10 in the listed requirements?
The original Steam review lists Windows 11 for both minimum and recommended configurations.
Does it include Japanese voices?
The original store-language review lists Japanese interface, subtitles and audio. This translation does not add a voice-playback test.
Is a GTX 1660 enough?
It is above the listed GTX 1650 GPU baseline, while RTX 3060 is recommended. Also check Windows 11, CPU, memory and storage; GPU alone is not a whole-system guarantee.
