Exterior design of the Sony KD-55XG8577

We have a simple design that has the necessary details to consider it good

The design is nothing to write home about, however, that simplicity makes it more striking than you might thinkIn addition, it has a very interesting elaboration that stands out at different points. In general terms we are going to witness a slightly elegant aesthetic that gives a modern touch and subtle in any setting.

First of all, we must talk about its front that offers us thin bezels that will take advantage of the screen quite well., here to be able to use about 94% of the useful area which will be a good space for content reproduction. Its sides are a little wider, but the frames as such will be thin and are a good complement to the rest of the design.

The back gives us a good elaboration that shows cleanliness and a different style to what we have seen in different models. The only thing we find in this space are the connectors that are located in a good way to access it more easily. Building materials are a bit weak, so, we must be careful when placing it.

Its brackets are a good size and thickness, therefore, They turn out to be very useful unlike others that are sometimes even cumbersome. In any case, we can choose to remove them and use the VESA that allows us to place the television on the wall, with this we will achieve a better integration with the design that is in the home. Remember that this is presented in silver with black.

Connectivity

This theme is not a problem and we have a large number of connectors that can be used for different actions. If you want to know in more detail what they are and the available tuners, We have left you a table of specifications at the top. In this case the most important thing is your three USB where we highlight that one is version 3.0, therefore, it will be perfect for transmitting large files. Likewise, there are four ports HDMI 2.0 (eARC; CEC). In the wireless we can use Wi-Fi, Bluetooth 4.2 and DLNA.

Image quality and features in general

Image quality is acceptable thanks to the different technologies implemented

Let’s move on to talk about the image quality offered by the Sony KD-55XG8577, which we think is quite good and meets our expectations very well. For starters, with an Edge LED panel that could be one of the weak spots, since the difference in quality is quite noticeable with the Direct LED that the 2020 models integrate, so, it will be a point to consider.

In any case it maintains some positive things, for example, its viewing angles that allow us to maintain the same definition from any position that we maintain, in addition, offers us a refresh rate of 100 Hz – 120 Hz, which is still a feature of high-end televisions. With this we achieve that the movements are more fluid without any type of cut.

Likewise, we are going to have some spectacular colors, in fact, Sony is considered by many experts to have the best ringtones on the market. In this case we have Live Color Technology and Triluminos Display that allow us to visualize completely natural and precise scenarios. And if that was not enough, the dynamic contrast will be exact to obtain great lighting in any environment.

Without a doubt, colorimetry is one of the strongest points that even make us want to buy this television. None of this would be possible without the support of a well-powered processor. For this model we find the X-1 that does not reach the quality of the Ultimate, but maintains a good performance, in addition, allows you to enjoy interesting scaling with a Super Bit mapping system.

Sound

Audio quality is not bad, it even seems enough to us at certain times or specific content. The only detail that we find as negative is the power of its speakers that still seems a bit limited. In this case we have 20W that will fall short in more demanding content, however, the inclusion of technologies such aso DTS Digital, Dolby Digital Plus and Dolby Atmos they offer us a more enveloping and clean sound. But the best thing is to buy an external sound bar that gives us all that missing audio.

Software review / Smart TV and other notable features

One of the most attractive things is its operating system

Finally, the Sony KD-55XG8577 offers us a very competitive operating system that has even been considered one of the best today. We are talking about Android 9.0 Pie, although we must mention that some televisions still integrate version 8.0 Oreo, so, you should take a good look before purchasing it. With this system we achieve the widest catalog of applications that reaches more than 5,000 optionsSo our entertainment is fully insured.

It obviously has compatibility with an advanced voice assistant that allows us better control of the television, since we can access actions very easily with the commands that we can create. Another interesting option is its compatibility with Dolby Vision, HDR10 and HLG dynamic formats that are responsible for further improving image quality in order to achieve greater details about each scene that we are viewing.

We end by mentioning that it includes technology 1000 Hz MotionFlow XR that allows us to enjoy a better behavior when playing, since it considerably reduces Input Lag and movements are usually more fluid and precise. Yes, this is the only option we have available for this topic, although for starters it can be a great option.
