Why cash deals require a simple test plan
When a sale is happening in person, buyers can feel rushed and skip key checks. A short fullscreen test sequence helps you stay objective and catch expensive display problems before it is too late.
Burn-in, tint, and dead pixels are all easier to judge when you know exactly what to check first.
Best 3-minute screen test before paying
Start with black, gray, and white, then use red, green, and blue if anything looks suspicious. Focus first on the status bar, keyboard area, corners, and center.
This sequence covers the most common OLED problems quickly without overwhelming the meetup.
How to respond if you find an issue
If the screen is clean, the deal is safer. If you see clear burn-in, tint, or dead pixels, lower the offer or skip the device instead of gambling on a defect you already noticed.
A few minutes of testing is far better than discovering the problem after the cash changes hands.
