Product Information

Small Size for a Big Picture

LG's 24LJ4540 24" HD 720p LED TV may be small in size, but it's got enough features to impress any viewer. HD Display, Triple XD Engine, and LED backlighting are just some of the treats to expect with this powerful TV.

Triple XD Engine

Triple XD Engine processes images with even greater precision to enable more natural color expression, deeper contrast, and a more life-like picture.


HDMI (High Definition Multimedia Interface) offers incredible audio/video quality and single-cable convenience. This monitor includes an HDMI input, so you can connect a true high-definition source, such as a high-end computer, Blu-ray player, or next-generation video game console.

LED Backlighting

LG's LED backlighting delivers exceptional brightness and amazing image clarity. You'll see richer colors and deeper blacks too, and LEDs offer greater energy efficiency compared to conventional LCD monitors.

No working headphone jack
It's ridiculous to have a headphone jack on the back of the tv but not have it work. LG says it does not have one because this is an entry level tv... where would you put an entry level tv? Kids room? Office? Use as a monitor? ALL USES THAT NEED HEADPHONES! Other than that its a tv that has average picture, average tv sound, and mediocre options. So disappointed in LG, returning this tv and purchasing another brand.

Performs as expected
Purchased two weeks ago, before the Covid-19 stay at home order. Our old kitchen TV was beginning to fail and we needed a TV about the same size as our old 19". Choose this model for its size, low price and pedistal stand as it has to sit on a small table. Was easy to setup as it's attached to a cable box. The picture was good but the sound was weak. Tweeked with the audio settings and is OK now.

Very happy with size of TV and easy installation
Picture very clear and the color is great. The speakers could be a little larger, however the sound is fair. Instructions and set up were really clear. Very happy with the product,

Perfectly suited as a desktop TV
This unit replaces a 10 year old (different manufacturer) TV that went black. Easy to install. Other than plugging in the unit, the only step required is to use the handheld to choose the source - HDMI, served from a cable box in my case.

light, thin and a great picture
I bought this as an extra tv for our motor home. It is light and has a good tuner that brings in channels clearly. Easy to set up and navigate

Instructions Difficult
I found the instructions hard to understand. I tried a few times and then stopped and haven't used the TV since.

Excellent TV
I bought this in early December to replace my kitchen TV. It has a very good quality picture and is easy to operate. My only small complaint is that it plays a tune every time It’s turned on and off. I find it a little annoying, especially since I can’t find a way to disable it.

Needs longer power cord from tv to AC Adaptor
I bought this tv a month ago to put on a bookshelf that is attached to wall (to prevent tipping over). The power cord from the tv to the AC adaptor is very short, so the AC adaptor doesn't reach down to the floor underneath the bookcase. There is not room behind the bookcase for the rather large AC adaptor. If the cord were just 2 feet longer, the AC adaptor would reach the floor and this would work. I called LG to see if they make a longer cord and not only do they not make such a cord, but they were completely unhelpful recommending someone who does. I hate to order something online that might not be compatible with the LG, which is why I contacted LG to start out with. Frustrating. TV may be good, but customer service is not, which kind of makes the quality of tv irrelevant IMHO
