Check the Basics First

Before diving into more technical solutions, start with the basics. Ensure your power cable is connected properly and that the monitor is receiving power. Flickering can sometimes be caused by a loose or damaged power cable. Try unplugging and replugging the monitor, and check for bent pins or physical damage on both the power and video cables.

Monitors like the Dark Matter 27-inch 165Hz and Dark Matter 49-inch ultrawide are known for stable refresh rates, so any instability likely stems from cable or port issues rather than the panel itself.

Update Graphics Drivers and Firmware

Outdated or incompatible graphics drivers are among the top causes of flickering or blank screens. Head over to your GPU manufacturer’s site—NVIDIA, AMD, or Intel—and download the latest stable drivers for your system.

Sometimes, Dark Matter gaming monitors receive firmware updates from Monoprice. These updates are rarely publicized, so check the official Monoprice site or contact their support to verify if a firmware update is available for your model.

Use the Correct Input Port (HDMI vs. DisplayPort)

Modern gaming monitors come with multiple input types, but not all ports are equal in performance. If you're using HDMI 1.4 or 2.0 on a monitor that supports DisplayPort 1.4, you might be limited in refresh rate or bandwidth. This can cause flickering, screen tearing, or even failure to display.

Try switching from HDMI to DisplayPort (or vice versa), and use certified high-speed cables. This is especially critical for high-res displays like the Dark Matter 5120x1440 ultrawide monitor, where bandwidth demands are significantly higher.

Calibrate the Monitor Settings

Improper brightness, contrast, or refresh rate settings can contribute to flickering or screen glitches. Access your Dark Matter monitor’s on-screen display (OSD) menu and reset to factory settings first.

Then, go into your GPU control panel and manually set the refresh rate (144Hz or 165Hz for most models) under display settings. This is especially helpful for users with the Dark Matter QHD IPS monitor, where manual refresh rate settings can override software defaults that cause flickering.

Windows Power & Display Settings Fix

On Windows PCs, certain power-saving settings may interfere with performance, causing your monitor to flicker or shut off intermittently. Navigate to:

Control Panel > Power Options > Set to High Performance

Also, disable Windows’ adaptive brightness and screen dimming settings. This can stabilize voltage regulation for the display, particularly useful for Monoprice Dark Matter 25S2G monitors that use USB-C or hybrid power inputs.

Check for GPU Overheating or Underclocking

Flickering issues aren't always monitor-related. If your GPU is overheating or underclocking itself due to power or thermal limitations, the display may lose sync. Monitor your GPU temperature using MSI Afterburner or HWMonitor.

Try running a GPU benchmark (like Heaven or FurMark) to see if screen flickering coincides with spikes in GPU load. This problem can sometimes manifest when pairing Dark Matter monitors with entry-level graphics cards that struggle to maintain frame sync at 144Hz+.

Test on Another PC or Monitor

To isolate the issue, try connecting the Dark Matter monitor to another PC or laptop. If the flickering continues, the issue likely lies with the monitor or cable. If it disappears, your original system could be at fault—either through driver conflict, power supply issues, or GPU errors.

This method is crucial when troubleshooting high-resolution monitors like the Dark Matter 32-inch 165Hz model, which may behave differently based on your system’s output capabilities.

FAQ

Why does my Dark Matter monitor flicker on startup?

It may be initializing at the wrong refresh rate or resolution. Adjust this in your GPU control panel and monitor OSD.

What’s the best cable for a 144Hz or 165Hz Dark Matter monitor?

Use DisplayPort 1.4 for best results; HDMI 2.0 is the minimum required for 144Hz at 1080p.

Can power-saving mode affect my monitor flickering?

Yes. Power-saving or adaptive brightness modes can reduce voltage consistency. Disable these in Windows settings.

How do I reset my Dark Matter monitor to factory settings?

Use the on-screen display (OSD) menu. Navigate to “System” or “Settings” and choose “Factory Reset.”

Where can I find a firmware update for my Dark Matter monitor?

Visit Monoprice’s official site or contact support. Firmware availability varies by model.

Conclusion

Dark Matter monitors are known for delivering incredible performance at budget-friendly prices, but flickering and display issues can ruin the experience. The good news? Most problems stem from basic misconfigurations, outdated drivers, or simple hardware compatibility issues.

By methodically checking cables, ports, settings, and your GPU’s performance, you can typically resolve these problems without needing to replace your monitor. Always stay updated with the latest drivers and monitor firmware for optimal stability.
