I am going to document the steps along the way to expose any issues and help others with similar display problems:

Thank you for contacting Dell Basic Hardware Warranty Support.

We have read your email and understand that the issue is “Bright white spot on your screen”

In order for me to isolate the exact point of failure and provide you with the right resolution, I would request you to perform/confirm the below troubleshooting steps and revert with the relevant results. (Ignore if any of the troubleshooting steps were already performed and update the remaining steps)

To reduce power usage on your notebook, an OLED panel dynamically adjusts the screen luminance based on its On-Pixel Ratio (OPR).

(On-Pixel Ratio represents the ratio of white pixels to the entire image.)

Because the panel can dynamically adjust the luminance, it can make the bright pixels that are displayed more bright by using the saved power from the dark pixels.

(If the ratio of white pixels is larger, then the brightness is lower, if the ratio of white pixels is smaller, then the brightness will be higher.)

This phenomenon is called the loading effect.

(Loading effect increases the peak brightness of the OLED panel with higher contrast.)

To reduce the frequency of the luminance adjustments, we recommended you run your applications in full-screen mode, or to optimize the PowerPoint theme and content, to reduce the OPR significant change.

This is because the OLED panel tries to enter the PSR to save the power, and exit the PSR when it detects the displayed content changed, the repeat action would cause the display Issue.

Please Power Down the System, Press and Hold D + Power Button
