Exterior design of the Panasonic TX-40JX820E

Panasonic TX-40JX820E design

We have the traditional design that has been applied to the televisions of this firm

The Panasonic TX40JX820E presents us with an aesthetic that we consider acceptable, since we have seen good details, although there are also aspects that improve, however, we must be aware that for this range they do not usually carry out such work designs . Therefore, we will consider that its appearance is a positive point.

The most attractive thing we are going to receive is on the front that presents us with thin bezels, which will bring out all the elegance that this model can offer , and for this to be even more visible we recommend placing the TV directly on the wall. Having such a fine frame will also benefit content playback.

We say this because the screen will have a much greater useful space that avoids seeing images with cuts. The rear part is regular and at the same time, in our point of view, it is the least attractive, since it shows a more exposed thickness, which always takes away from the design . Another thing that did not convince us too much is that its construction is weak.


We receive a normal connectivity that offers the essential ports for an optimal work of the TV. Here we can see three HDMI that we can use to connect external devices and send their signal, likewise, we have two USB ports that allow the reproduction of content or if you prefer it will also be possible to record it directly from the television. The wireless options are remarkable, since we have Wi-Fi , Bluetooth and DLNA .

Image quality and general functions of the Panasonic 40JX820E

We come to the most prominent section of the Panasonic 40JX820E , since it gives us a fairly optimized image that will be sensational for any content. We must start from its 4K resolution that gives us four times more power than Full HD, therefore, the details in this model will be more precise , which translates into more realism.

It includes an LED panel that we could consider as the least attractive, since we have noticed a bit of complications in very dark or bright environments, therefore, taking care of the location can end up being a positive point . Although we should not worry too much, since we have improvement technologies that help too much.

The advantage is that they focus on specific parameters that are essential for a good experience. For example, the color receives an important improvement so that we can visualize it in a more natural way . Likewise, it happens with the contrast that Ultimate Contrast includes, a function that will show it more clearly and deeply.

Obviously there will be more technologies that will give a great contribution to aspects such as brightness and saturation, as if that were not enough, the movements will be quite fluid so that the image does not present obstacles at any time. We cannot forget that this TV provides compatibility with Filmmaker Mode and HDR formats for a greater experience.


If the Panasonic TX-40JX820E lacks something, it is a good audio quality, since it only delivers 20W of total power, which is not usually recommended for more demanding content. It is true that it has Surround Sound that seeks to give us a more enveloping and clean experience, however, it is best to buy a sound bar.

Panasonic TX40JX820E Software / Smart TV Review and More

Panasonic TX-40JX820E Smart TV

We receive the advantage of having the Android system that fills us with great possibilities

Normally the televisions of this firm have their own operating system, however, for this series they have decided to use Android TV, which for many is a great advance , since it is a fairly complete system if we talk about entertainment or functions that we can to take advantage of. This makes the Panasonic TX40JX820E more interesting .

To begin with, it is a well-optimized system that gives us a fairly fluid and intuitive navigation. Another of its greatest attractions is that it offers us a really extensive catalog of applications where we can find more than 5,000 options to install. Obviously taking into account the most popular streaming platforms .

We can also download movies, music and games to enjoy on the Panasonic 40JX820E , however, much of this content is already paid. Let’s talk rather about how useful the inclusion of Google Assistant is , since we will be able to control certain functions using the voice, and to transmit content from any device we have Chromecast .
