Overview
The LG 24LJ4540 is a 24 inch LED television built around LG's webOS smart platform, with a 720p HD panel and Bluetooth for pairing headphones or a soundbar. Its compact 5.8 x 21.9 x 15.2 inch footprint and 7.5 pound weight suit small rooms rather than a main living room.
At 24 inches this sits at the small end of LG's smart TV lineup, aimed at a bedroom, kitchen or dorm rather than a primary screen. The 720p panel keeps detail modest next to 4K sets, but webOS gives it app support that plainer small TVs often skip.

Who it's for
Fits buyers who need a second or third TV for a small space and want smart apps built in. It is not the choice for anyone wanting a large-format or high-resolution main display.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact footprint fits tight spaces
- WebOS adds smart app support
- Bluetooth allows wireless audio
- 720p resolution limits detail versus 4K sets
- 24 inch screen too small for a main living room
Performance notes
The 720p LED panel runs at a standard 60Hz refresh, adequate for cable and streaming video at this size. webOS handles the app store and menu navigation, and Bluetooth lets you pair audio gear wirelessly instead of running a cable to a soundbar.
