Few things are more frustrating than launching a game and being met with nothing – we mean a black screen. No menu, no logo, not even an error message. This is exactly what some PC players are dealing with in Killing Floor 3. And unlike crashing or stuttering, a black screen issue doesn’t give you any real clues, as you’re just staring at a plain black screen. You can’t even get into the settings to adjust anything, which makes it even harder to troubleshoot.
The good news? You’re not alone, and there are a few things you can try to fix it. Sometimes, the cause is something small, like a temporary glitch, outdated drivers, or even a loose cable. In this guide, we’ll walk you through a handful of methods that will help fix the issue in no time.

Make sure your GPU drivers are updated
Your graphics card plays a huge role in launching and running games smoothly. If the drivers are out of date or corrupted, it can cause display issues, including black screens. Killing Floor 3 is a new game, and it likely needs the latest GPU drivers to function properly. Thankfully, you can use the Nvidia App or AMD Radeon Software, depending on your GPU brand, to download the latest version quickly. Or, you can simply head over to the official website of your GPU’s manufacturer, search for your exact model, and download its drivers from there.

Repair game files
Sometimes a file might go missing or get corrupted during the installation process. This can easily lead to black screen problems, as the game does not have the proper files to launch or run smoothly. Thankfully, Steam offers a quick way to repair or recover such files without reinstalling the game.
- Open Steam and go to your Library.
- Right-click on Killing Floor 3 and select Properties.
- Go to the Installed Files tab.
- From the right side, select ‘Verify integrity of game files.’

Check the HDMI/DP cable and ports
This might seem basic, but it’s worth checking. If your HDMI or DisplayPort cable is loose, damaged, or not properly connected, it could cause display issues like a black screen. Also, dust or debris inside your GPU’s display ports or monitor can block proper signal transmission.
For this, unplug your HDMI or DP cable from both your GPU and monitor, and then inspect the ends for damage or dirt. We also recommend using compressed air to clear out dust from the ports. You can also blow gently into the ports if you don’t have compressed air.
