Troubleshooting a Dark Laptop Screen: How to Fix an HP 655 Screen That's Too Dark

Replacing your laptop screen is a significant investment, but achieving optimal brightness and functionality is equally important. If your new screen on an HP 655 laptop feels too dark or is barely visible, this guide will walk you through several methods to resolve the issue and help you get the best performance out of your device.

Identifying the Cause

A dark laptop screen may be due to various reasons, ranging from misconfigured display settings to hardware issues. Here’s a breakdown of some common causes and solutions:

Display Resolution Misconfiguration

One common reason why your new screen may appear too dark is a misconfigured display resolution. This can easily be corrected through the Windows settings.

Open the Settings app on your computer.

Click the System category and then Display.

Video Signal Issues

The screen may also be dark due to video signal issues, which could result from loose cables, a faulty graphics driver, or even a hardware problem within the graphics card.

How to Fix the Dark Screen

Adjust Brightness Settings:

Use the Function (Fn) keys on your keyboard to adjust the brightness. Keys like Fn F2 or Fn F3 often correspond to increasing or decreasing brightness.

Through the Windows Settings:

Right-click on the desktop and select Display settings. Scroll down to the Brightness and color section and adjust the brightness slider.

Check Graphics Settings:

Click on the desktop and select your graphics control panel, such as NVIDIA Control Panel or Intel Graphics Settings. Look for brightness or display settings and adjust accordingly.

Update Display Drivers:

Press Windows X and select Device Manager. Expand Display adapters and right-click your graphics card to Update driver. Select Search automatically for updated driver software.

Check Power Settings:

Go to Control Panel Power Options. Ensure your power plan isn’t limiting brightness. Consider changing to a different plan or adjusting the brightness settings within the current plan.

Check for Hardware Issues:

Check if the screen is properly connected. If you recently replaced it, there may still be a loose connection. Inspect the screen for any physical defects or damage.

Adjust Color Calibration:

Type calibrate display color in the Windows search bar and follow the prompts to adjust color settings that might be affecting visibility.

Try Connecting to an External Monitor:

Connect your laptop to an external monitor to see if the brightness issue persists. If it does, the problem may be with the graphics card rather than the screen.

Return or Replace the Screen:

If none of the above solutions work, the new screen might be defective or incompatible. Contact the supplier or manufacturer for a replacement.

Conclusion

Trial and error with these steps can often resolve the issue. However, if the problem continues after thorough troubleshooting, it might be best to consult a professional technician who can provide more advanced diagnostics and repairs. Remember, a well-functioning screen is key to ensuring your HP 655 laptop provides the best user experience.
