I'm happy with my WMF toaster. But seems I should try others...

I'm cautious and aware of the burn-in risk. So if I have something opened for too long that might burn in, I do a switch. But in the end it shouldn't be too sensitive. For example the MSI I have has:

1. Pixel Shift

The image is imperceptibly shifted by a few pixels in different directions at regular intervals. This prevents a sharp edge (such as a crosshair or UI bar) from permanently straining the same pixels.

1. Panel Protect

Pixel Refresh: After about 4 hours of use, the monitor prompts you to take a short break (approx. 5–10 minutes). This equalizes the pixel voltages.

Panel refresh: A more thorough cycle that is performed after a longer period of operation (usually 1500+ hours) to homogenize the brightness.

1. Static object detection (intelligent dimming)

Certain static content that remains permanently, e.g., Excel windows, is dimmed, for example, when working from home.

A good one, even if already aged. But aged well!

With my OLED I changed the display off time to prevent burn-in. So far no issues.
