Exterior design of the Sony KD-65XG8577

A design that unleashes elegance from any angle

We are going to visualize a simple design that does not present very striking details, however, this is what makes almost any eye look attractive. Its elaboration is truly interesting and for that year it was one of the best appearances. This was because it gave us a good integration no matter where you are.

Almost all its elegance is thanks to those slim bezels that generate a modern and fine style. With this we are going to get a clean view of the screen that in turn will have better dimensions that translate into a more complete content that will not have cuts in the image. Definitely, the front is the best of its aesthetics.

If we turn the television over, we will notice that it has a different style thanks to the fact that there are no boards as in other models. Namely, that remains thin at all timesAs if that were not enough, they have resistant construction materials that are almost entirely based on aluminum, this gives us a lot of security.


We have the expected connectors for a good experience. Highlighting the inclusion of four HDMI 2.0 (eARC; CEC) They offer good stability and transmission when connecting laptops, consoles or players. We also have three USB where we are surprised that one is version 3.0, which offers us a perfect data transmission for heavy files when recording content.

You can check the rest of the physical connections in the specifications table, likewise, we leave you the tuners that will be compatible with this equipment. At the wireless level we have very valuable options that will be totally useful. Here we have Wifi to make use of the internet, likewise, we have compatibility with Bluetooth 4.2 to connect other types of devices, there are also DLNA.

Image quality and functions in general

Sony KD-65XG8577 picture

We find that its image quality is one of the most interesting in the mid-range

The image quality presented by the Sony KD-65XG8577 it is expected for a model of its value. We believe that it can meet the expectations that you can generate. First, we have an Edge LED panel that we consider the least attractive on this subject, since its power in the backlight may be short.

However, this is somewhat addressed with the inclusion of technologies and settings for the image. For a start, it has a 4K resolution that will give us a more realistic content in case it is nativeHowever, it also implements 4K Upscaler so that what is in a lower definition increases its quality.

Other details that seem positive to us begin with the fact that we have viewing angles that maintain the same quality regardless of our position. We are also offered a refresh rate of 120 Hz which is considered a high-end feature., since with this we are going to visualize more fluid images.

For the color theme we are offered Live Color that offers us a spectacular environment with totally intense and vivid colors that will give more detail to each scene. Dynamic contrast maintains good sharpness and this allows us to maintain quality in dark or bright environments without losing much image quality.

All this is achieved with the implementation of the X-1 processor that does not have the power of the Ultimate seen in the most recent models. However, it maintains a smooth operation at all times. As expected, it has compatibility with Dolby Vision, HDR10 and HGL formats that further enhance each scene.


We have an interesting audio that we think is sufficient for certain not so demanding content. The only negative detail that we find is that the power of its speakers is low, especially considering the rest of the features implemented. Here we are going to find two integrated speakers that offer us a total power of 20W, yes, improvement technologies are included.

These options will allow us to experience a more enveloping and clean sound. The improvement is not incredible, however, if they end up being helpful. In this case we enjoy DTS Digital, Dolby Digital Plus and Dolby Atmos functions that we usually see in the high-end range of entry and are really useful. Here the problem is the speakers. So the best we can do is get a cheap soundbar.
