A small number of users with NVIDIA graphics cards have reported a problem with visible green lines flickering, flashing, or "strobing" on screen while playing The Bard's Tale IV, particularly in fullscreen mode.
This appears to be caused by an incorrect color configuration in the user's display output settings. If you experience this issue, you should be able to resolve it by following the steps below.
- Open the NVIDIA Control Panel (either from Control Panel in Windows, or by right-clicking on your desktop and selecting "NVIDIA Control Panel").
- Once the NVIDIA Control Panel appears, navigate to Display -> Change resolution.
- Under "Apply the following settings", select "Use NVIDIA color settings".
- You may need to adjust the settings to match your display's output. For most PC monitors, you should select 32-bit desktop color depth, 8-bit output depth (10-bit if your display supports it), RGB color format, and Full dynamic range.
- Once changes have been made, click the "Apply" button.
Additional Display Issues
If you continue to experience display corruption problems, especially in other games or on the desktop itself, there may be a different cause of the problem.
- An overclocked graphics card will often show image corruption artifacts. If you have overclocked your graphics card, try removing any overclocks and see if that resolves the issue.
- An overheating graphics card can also display image corruption. We recommend checking your graphic's card temperature while playing. Exact safe bounds vary based on your graphics card, but a temperature around 100 degrees Celsius or higher is often unsafe, and may cause damage over sustained periods of time. We recommend checking with your display manufacturer for more details if you suspect your graphics card is overheating or may be damaged.
- A broken, partially disconnected, or damaged cable could cause display problems. To resolve this, you can try re-plugging the cable, or using a different cable type. For example, try using a different cable, switching DisplayPort for HDMI, or using a different slot if your graphics card or display have multiple inputs/outputs.
