A 75 inch uhd 4k tv can only be described as a massive TV. Hence, before opting to procure it, one should ensure the availability of ample space both to set it up and to experience its magic in true glory.

Specific features of the 75 inch 4K smart TV
Some of the features that make for good 75 inch 4k tv reviews are:
Build and design: There has been a drastic change in the build and design of the high end Android Smart TV currently available. They are thin, sleek looking, weigh comfortably less and can be either wall mounted or kept on the stand. These Smart TVs might look fragile but they have a sturdy built. The connectivity options, the headphone jack etc. are all neatly arranged on the side of the TV panel thereby concealing them yet increasing their utility.
Picture quality: The 4K resolution coupled with the massive size make for a beautiful TV viewing experience. The 4K HDR makes the picture quality crisp and vibrant. The colour distribution is also uniform and there are no visible grains or colour bands. One colour blends beautifully into the other. The colours are bright but soothing and make individual components of the screen stand out. 

While content is being specifically made for 4K output, there is still a lot of content still being made to suite the 1080p format. Many people think that buying a 4k android smart tv would prevent them from watching 1080p content. However, this is not true. In fact, the transmission or streaming of such content on a 4K 75-inch smart screen enhances the viewing quality of the content. 
Gaming: Herein the gamer gets an almost 3D type 360-degree all-encompassing and mesmerising experience. The HDR representation is extremely good, minute details are visible and the colour quantum is well adjusted. By supporting such 4K gaming devices like the PS4 Pro and the Xbox One X, it takes gaming to a level wherein the player gets an immersive experience. 
UI: Since these Smart TVs use the android platform, they are easy to use, convenient and give the viewer access to innumerable apps found on the Play Store. 
Audio: Most high end Smart TVs support Dolby Vision sound. Thus, the audio output has a lot of clarity. Movie dialogues even with music playing in the background can be heard properly. 

However, inspite of all the advantages mentioned, a TV of this size can also be relatively more expensive. Thus, one should not be easily swayed by talks of 8K or 4K technology or AI Android combinations etc. This TV is meant to provide an immersive 360-degree experience. Procuring this TV thus, should be a well thought after decision.
