Why Marketplace sellers should test first
A buyer meeting in person usually expects a fast but honest assessment of the monitor. Burn-in, dead pixels, and uniformity are the biggest concerns on used OLED panels.
Testing first helps you write a clearer listing and defend the asking price with real panel details.
Best pre-listing monitor test flow
Use black and gray for taskbar wear and banding, then white and primary colors for tint and dead pixels. Check the screen from normal desk distance before moving closer.
If the panel has flaws, note whether they are visible in the center, along the lower edge, or only from very close range.
How to present the condition to buyers
If the monitor is clean, mention that you tested for burn-in, dead pixels, and uniformity. If issues exist, describe them clearly and price the unit accordingly.
An accurate description usually leads to better buyer trust and faster local sales.
