Should I buy a used LG OLED or a new Hisense Mini LED?

Choosing between a used LG OLED and a new Hisense Mini LED comes down to your room's lighting and your tolerance for risk.

When to buy the New Hisense Mini LED:
This is the safest and most practical choice for most people. A new Hisense Mini LED (like the U8 series) offers massive peak brightness, making it perfect for living rooms with plenty of sunlight. Because it's a new Mini LED, you get a full manufacturer warranty and absolutely zero risk of permanent burn-in. While the black levels won't be quite as perfect as an OLED, modern Mini LEDs get remarkably close without the associated risks.

When to buy the Used LG OLED:
Choose the used OLED only if you are a cinephile watching primarily in a dark room and you are comfortable assessing a used TV. OLED technology offers perfect black levels, infinite contrast, and superior viewing angles. However, buying a used OLED carries the risk of "burn-in" (permanent image retention) from the previous owner's viewing habits, and you will not have a warranty if something breaks. If you go this route, always run a solid color test screen (red, magenta, and gray) before handing over the cash to check for hidden burn-in.
