Why sellers should test before shipping
Once the item is shipped, any disagreement about screen condition becomes harder to resolve. A final OLED test helps sellers document the panel honestly before it leaves their hands.
That is especially useful for phones, tablets, and monitors where burn-in and dead pixels are common buyer concerns.
Best final test before packing
Use black, gray, and white first, then red, green, and blue if anything looks suspicious. Take clear photos if you see any flaws or if you want to prove that the panel was clean before shipping.
Check the status bar, keyboard area, corners, and any repeated UI zones because those are common OLED problem areas.
How to use the result in your listing
If the panel is clean, mention that you tested it before shipping. If there are flaws, describe them accurately so the buyer knows what to expect.
Clear condition details reduce the chance of returns, complaints, and payment disputes.
