A small, light screen for a desk, counter or spare room where a full-size television will not go. Its single HDMI input and low resolution are the trade-offs to accept at this size.

Overview
Not a wall-filling living room television, but a compact LED screen for a desk, countertop or small room. Images pass through the Triple XD Engine, which sharpens color and contrast before they reach the panel, and the ATSC tuner pulls in over-the-air channels without a separate box. A stand, remote and power cable come in the box.
A buyer short on space gets a light panel that lifts onto a counter or desk without help and tunes local broadcasts on its own. The picture tops out at 720p, so it suits casual viewing rather than a main home theater seat, and one HDMI input limits how many sources stay plugged in at once.
Who it's for
A dorm room, office desk or guest bedroom where the screen has to stay compact and light. Someone who wants several consoles and players connected at once should look elsewhere, since only one HDMI input is on the back.
Pros and cons
- Compact footprint for desks and counters
- Light enough for one person to move
- ATSC tuner picks up broadcast channels
- Built-in speakers need no soundbar
- 720p resolution, not full HD
- Only one HDMI input
- No voice control listed
- Smart app support not stated in the listing
Performance notes
Picture quality comes from the LED backlight and the Triple XD Engine processing, which works on color and contrast before display. The refresh rate and response time keep motion steady for casual shows, while the contrast ratio and brightness set how much punch the panel can show in a lit room.

Frequently asked questions
Can the LG 24LJ4540 be mounted on a wall?
Yes. It carries a 75 x 75 mm VESA pattern, so a bracket or arm with that hole spacing fits. The stand is what comes in the box, and a mount is not included.
How many devices can stay connected to the LG 24LJ4540 at once?
One HDMI source at a time, plus one USB device, one VGA input and one component output. A computer, Blu-ray player or game console can use the HDMI port.
Does the LG 24LJ4540 need a cable box to show channels?
No. The built-in ATSC tuner receives over-the-air broadcasts, so an antenna is enough for local channels.
How much room does the LG 24LJ4540 take on a desk?
The panel measures 21.9 inches wide, 15.2 inches high and 5.8 inches deep, and weighs 7.5 pounds, so it fits a counter or desk without much clearance.
