Design and connectivity of the Sony KD-43X73K

With the Sony 43X73K model we are enjoying a light, modern style without any frills . It has a thin bezel in black and a smooth semi-polished finish that outlines the entire panel, creating on this occasion, minimal front frames . They do not cloud the image, much less, but we cannot speak of an all-screen effect as other more expensive ones have.

Its support is none other than, as is often the case at Sony, two metal legs that, in this case, are made of a thin sheet , much more aesthetic than the usual wide and plastic ones.

To discover how it will be more comfortable to locate it, we leave you its measurements and weight. If you want the Sony KD-43X73K as such, it measures 617 x 970 x 209 mm and weighs 9.1 kg (0.1 kg each leg. If it does not suit you to put it on a piece of furniture, you always have the option of placing it on your wall. In this case you you will find a 567 x 970 x 84 mm panel that weighs 8.9 kilos Be careful because you need a 20 x 20 cm VESA wall mount to hang it, of course.

Tuning and connectivity

I love this Sony 43X73K model that, in terms of wireless connection, comes with bluetooth in 5.1 ! In addition, it has certified 5G WiFI , so connection problems should not exist.

We don’t forget the rest, quad HDMI 2.0 that supports eARC, ARC and HDCP 2.2, an RJ 45 in case you want to connect the Sony KD-43X73K to your wired network, an optical digital audio output, two USB 2.0 ports (one of them allows you to record the content that is broadcast on TV) and a 3.5 mm jack for headphones.

Image quality and general functions of the Sony KD-43X73K

We have with us a 43-inch LCD panel with a resolution of 3840 x 2160 pixels (UHD) , which translates into a very high ppi of 103. This is the first way in which Sony uses resources well to give much more detailed images. Still, the BRAVIA Engine produces the highest definition images regardless of whether they come digital or analog. The array is 10-bit VA falsified by FRC .

Its backlighting is conventional, DLED or direct LED type. We have a conventional frame dimming, dynamic contrast enhancement and a refresh rate of 50 Hz to which Motion Flow XR helps with a small contribution of 200 units for this model.

Color enhancement comes with the inclusion of a TRILUMINOS display as well as Live Colour , a technology that has been successful on Sony TVs for years.

For this model, Sony chooses Vivid, Cinema, Game, Sports, Energy Saving, User and Standard picture modes .

oh! I forget it! You have basic HDR support including HDR HLG and HDR10 .


Sony puts 20 W of sound power in front of us , as is done with almost any mid-range like the Sony KD43X73KPAEP. They are given in two conventional channels with bass reflex loudspeakers .

There is no compatibility with DTS at any level but with Dolby .

You have the options of Live, Sports, News, Cinema, Standard and User as modes so that the TV adapts the corresponding values ​​and offers you better audio.

Software/smartTV analysis

Android TV 11 is the one chosen to shape this model.

It is accompanied by other Google services such as Chromecast, with which you can pass what you are playing on your mobile or tablet to the television to see it large and share it.

Likewise, you have full access to the Google Play Store app store , with which you will feed your TV with as much software as you need. You can download both the free ones and the paid ones (prepaid, of course, hehe) and of any type (games, utilities, streaming platforms… In fact, this is the largest application store that exists so far.

When you are using HbbTV you will have a browser called iWedia . For the rest, don’t worry because you can do your searches by voice, really. Google Assistant will do it for you directly or indirectly with OK Google if you install another device that is compatible with the assistant.

The interface that you can see is really practical . Everything is found in a moment, with clear and well-defined menus and, in addition, it is quite aesthetic, which is always appreciated when we are using a device for a long time.

You’ll be glad to know that Android allows you to put your favorite apps on the main interface so you can see them as soon as you turn on the TV.
