Question Monitor Flickering Issue on Dell S3422DWG Gaming Curved Monitor 34" WQHD

[praveenk72007]

Issue Description: The monitor exhibits consistent flickering, as shown in the video below. This flickering is present in every frame, indicating a persistent issue rather than an intermittent one. The flickering manifests as significant changes in brightness or color between consecutive frames. If the flickering continues for an extended period, the screen sometimes goes black for a long time. To resolve this, I have to turn off the monitor for a while, after which the issue temporarily resolves.
Initially, I suspected electrical interference, as there is a Wi-Fi router installed near the screen. However, even after switching off the Wi-Fi, the issue persisted for at least 30 seconds.

Things Checked:

• Switched cable connections, but the problem persists.
• Adjusted the refresh rate to "Auto."
• Tested the monitor with different devices.

Verify that I found the applicable monitor.

Are the monitor drivers installed?

If not, manually download from Dell's website. Install and configure as required.

If the driver is installed then download again and reinstall.
