Design and connectivity of the Sony XR42A90KAEP

The model, with its base, measures 551 x 933 x 225 mm and weighs 16.4 kg . Its surface is made of metal and it has no edges , being its central aluminum plate mounted in titanium black . This is 50 cm, rectangular with fully rounded corners . I love that in Sony XR42A90KAEP you have two options to place the stand : one with which the panel is immediately above, flush with the furniture and another that is achieved by giving it more height to conveniently place a sound bar just below.

On the other hand, you have the panel itself, which can also be hung and used on the wall via a 200 x 200 mm VESA mount . This time it would simply measure 546 x 933 x 57 mm .

Tuning and connectivity

How could it be otherwise, we came across a television with very good tuning, discovering HbbTV and CI+ , although without knowing versions, an analog (B/G, D/K, I) and digital in DVB-C/S2/ T2 .

To use them we have a composite video in mini-connector, RF antenna, double satellite and CI slot .

These physical connections end with two USB given in 2.0 (with one you can record content on external HDD), two HDMI 2.0 and many others in 2.1 . These provide almost complete support for HDCP 2.3, eARC, CEC, ARC, VRR and ALLM. We also have a plug to connect cable TV to the network and an optical digital audio output.

We would have the wireless connection, consisting of Wi-Fi Certified 802.11a/b/g/n/ac , that is, in 2.4 and 5GHz as well as bluetooth in 4.2 .

Image quality and general functions

Beautiful 42-inch OLED panel with UHD resolution , which achieves a very high ppi of 41 pixels per square centimeter. The matrix is ​​30 bits and the color depth is true 10 , which allows us to see 1073741824 colors without distortions due to angle or environmental conditions.

The improvements to achieve an outstanding image are given as follows.

  • Contrast . This model, although it works in other ways, includes an improvement of the conventional dynamic contrast. It is accompanied by Pixel Contrast Booster, XR HDR Remaster , which is exclusively in charge of HDR contrasts and XR OLED Contrast Pro , a double-layer system that maps color temperature on the one hand and, on the other, adds a luminance layer.
How XR OLED Contrast Pro works

How XR OLED Contrast Pro works

  • colour . The color is chosen with XR TRILUMINOS PRO , a type of display with its own color palette. Live Color takes care of always achieving the maximum color vibrancy and XR Smoothing balances the latter so that the results are always realistic and consistent with what the human being can see.
  • Clarity . To achieve an improvement in clarity, the first thing that is done is a reconversion of the content to a resolution as high as possible with 4K XR Upscaling . This uses two other techniques, XR Super Resolution and a dual database processing .
  • Movement . The panel natively integrates 100 Hz adaptive , being able to work with them from 40 and stretching them up to 120. With an auto mode, the TV uses XR OLED Motion , which avoids the blurring that usually occurs due to cross movements. It does this by cognitively creating extra frames that keep the action sharp and smooth. An input lag of only 8.5 ms is achieved , which makes the Sony XR-42A90K an ideal TV for gaming in conjunction with the HDMI 2.1 support that we have seen before and the rest of improvements such as automatic tone mapping, action in 4K at 120fps or automatic picture-by-genre mode.

Incidentally, the model includes support for HLG, HDR 10 and Dolby Vision standards .

With the light sensor capable of capturing environmental conditions and the numerous image modes , the Sony Master Series BRAVIA XR finishes adapting each image so that we see it in the most comfortable and realistic way.


Despite being tiny, this cutie packs 25W , which is already 5 more than usual on most TVs. They come diced in a very small woofer . The 10W speakers are  Acoustic Surface Audio+ drivers . These seek sound distribution based on what’s around the TV, including yourself so you’re always the center of the action.

Format support is great, including Dolby Atmos and DTS Digital Surround , so you’ll hear it all.

With other elements such as voice zoom, room compensation, the sensor that we have already talked about or the audio modes, you finish adjusting all the values ​​of what you hear so that the sound is the best possible.

Sony Master Series BRAVIA XR 42A90K smartTV/software review

For the Google model, it gets fully involved and inserts its Android TV 10 as well as Google TV to customize the interface.

This means that, as you suppose, you have all kinds of services from the huge company, which is an excellent idea.

First and foremost is that you have the best application store of the moment . Here you will see absolutely everything, not to mention those that have already been pre-installed on the television. Games, managers, players… You have whatever you want. Similarly you can buy books and movies from Google Music and Movies respectively.

And if what you’re looking for doesn’t have an app, don’t worry because you also have a browser, Vewd , which will make your experience like being on a computer.

Other Google services that you are going to see are Chromecast , with which you will mirror from your phone or Google Assistant . But don’t worry because if they don’t work for you or don’t interest you, the TV comes with a built-in solution, AirPlay 2 for Apple and Alexa as an assistant.

This model can incorporate a web cam that will serve both to make video calls (Google puts DUO) and to help the television with its sensor to recognize you and your environment.
