TV Buying Guide

An 8K TV is a TV that has a screen with 7,680 horizontal and 4,320 vertical pixels for a total of approximately 33 million pixels. The "K" in 8K stands for Kilo (1000), meaning a TV with a horizonal resolution of about 8,000 pixels.

8K TV is the highest resolution TV recently released among UHD (ultra high definition) TVs. With four times more pixels than a 4K TV—another type of UHD resolution—8K TVs show a sharper and more detailed picture quality. This is because in 8K TVs, pixels are so small they cannot be distinguished even from close up, making highly detailed images a reality.

So, how good are 8K TVs compared to other TVs? Let's compare them to Full HD TVs and 4K UHD TVs to find out.

The resolution in 8K TVs is 4 times higher than that of 4K UHD TVs, and 16 times higher than Full HD TVs. Higher resolution means that there are more pixels that make up the screen. In other words, on the same size TVs, pixels are more densely packed within the same area which allows for a much more sophisticated and realistic image representation. This provides an overwhelming sense of immersion when you watch TV.

The term used to describe the number of pixels in a given area is called PPI (Pixels Per Inch), and naturally a higher PPI number means higher pixel density. Typically, on a 75" 8K TV the PPI is 117 while on a 4K TV and FHD TV it's 59 PPI and 29 PPI respectively.

All 8K TVs have Upscaling technology, however every TV maker implements their own specific technology to produce 8K-like quality visuals.

In 2019, Samsung 8K TV is introduced with its own specialised 8K AI Upscaling technology. The AI Upscaling technology uses a method that collects and learns a wide variety of content characteristics by type and then stores them in a database. It later uses that database to process similar image types again, making for a much more sophisticated Upscaling process. With Upscaling being so important and various choices available, take the time to compare and make a well-informed decision.
