Is the LG B56LA good for gaming?

It handles consoles at 4K with low input lag, but it has fewer gaming features than LG's C-series. Serious gamers should compare the two before choosing.

How is it different from LG's C-series OLED?

The B-series is the entry line: it is dimmer and has a simpler processor and fewer gaming features. The C-series costs more but is brighter and better equipped.

Is a 48-inch OLED big enough for a living room?

It suits small to medium rooms and viewing distances of roughly 5 to 8 feet. For a large, bright living room, a bigger or brighter set is usually a better fit.

Does it support 4K streaming apps?

Yes. webOS includes the major streaming services, and the set upscales lower-resolution content to 4K.

Should I worry about OLED burn-in?

Image retention is possible if static logos or tickers stay on screen for hours at a time. Varying content and using the screen-off timer reduces the risk.
