High Stakes and Black Screens: Addressing the Samsung G7 4K’s Gaming Glitches



Intermittent Monitor Blackout During Gameplay on Samsung G7 4K @144Hz


Dear Expert,

I have been experiencing an issue with my Samsung G7 4K monitor, which operates at 144Hz. While playing certain video games, such as Mini Motorways and League of Legends (specifically on the Howling Abyss map), the monitor intermittently turns off and then back on. This problem seems to be exacerbated in games that frequently alternate between bright and dark colors.

Despite my efforts, including toggling HDR, recalibrating it, and switching DisplayPort cables across different GPU ports, the issue persists. My system is up-to-date with the latest NVIDIA drivers and Windows updates. The hardware specifications are as follows:

  • CPU: Intel Core i9-12900k at 5.20 GHz
  • RAM: 32GB Dominator Platinum RGB at 5600MHz
  • GPU: Asus RTX 3080ti
  • Motherboard: MSI Z690 Carbon
  • PSU: 1000W Corsair
  • Unfortunately, I have not found similar cases online and am seeking your expertise. Have you encountered such an issue before, and if so, could you provide any guidance on resolving it?

    Thank you for your assistance.

Dear Inquirer,

Thank you for reaching out with your concern regarding the intermittent blackout issues with your Samsung G7 4K monitor at 144Hz. The symptoms you’ve described are indeed perplexing, particularly since you’ve already undertaken several troubleshooting steps to no avail.

The issue of the screen turning off and on during gameplay, especially in titles with rapidly changing light and dark sequences, could be indicative of a few potential problems. Firstly, it’s important to rule out any software-related conflicts. Given that you’ve updated your NVIDIA drivers and Windows OS, we can look towards other possibilities.

One potential cause could be the Adaptive Sync technology, which might be struggling to maintain synchronization with the game’s frame rate, leading to the monitor’s blackout episodes. It’s worth checking if disabling any G-Sync or FreeSync settings alleviates the issue.

Another possibility is a power supply inconsistency. Despite having a robust 1000W Corsair PSU, it’s crucial to ensure that the power delivery to your monitor is stable. Fluctuations in the electrical supply could cause the monitor to reset intermittently.

Additionally, monitor firmware can sometimes be the culprit. An outdated firmware version might not be fully compatible with certain games or graphical settings, leading to instability. Check the manufacturer’s website for any firmware updates that might address this issue.

Lastly, the problem could be hardware-related. The monitor itself might have a failing component, such as the power supply unit or the mainboard, which could cause it to turn off and on under specific conditions. If the monitor is still under warranty, consider reaching out to Samsung for a professional diagnostic.

In summary, here are the steps you can take to further diagnose and potentially resolve the issue:

1. Disable any Adaptive Sync settings temporarily to test monitor stability.

2. Verify the stability of your electrical supply and the integrity of the power cable and connection.

3. Check for and apply any available firmware updates for your monitor.

4. If the issue persists, contact Samsung support for a warranty claim or repair service.

I hope this response provides you with a clear direction for resolving the blackout issue with your monitor. Should you require further assistance, please do not hesitate to reach out.

Best regards,
