Ultra HD Televisions

Ultra HD TVs are designed for demanding customers who need a very sharp image. With a 3840 × 2160 resolution, or roughly 8.3 million pixels, these TVs deliver four times the resolution than standard Full HD TVs. At such high resolutions, individual pixels become invisible, so you will see the finest details even standing very close to the screen. What are the other benefits of 4K TVs?

The Main Benefits of 4K TVs

High resolution delivers crisp details.
The HDR standard offers an image with a richer range of colors.
Higher frame rates ensure a smoother and sharper image.
Using the Upscaling feature, lower resolution images are converted into 4K quality.
Higher pixel density allows watching 4K televisions from a smaller distance.
Powerful 4K TVs can handle high-speed Internet browsing and app usage.
Today, there is plenty of content at 4K resolution, so a 4K TV is now worth the investment.

Important Parameters to Consider When Buying a 4K TV

Screen Size

The majority of 4K TVs have screens sizes of 55" (140cm) and larger, and when viewed, the optimal eye distance from the screen is 1.5 times its height, which is approximately 1.2m. When choosing the screen size, take into consideration the layout of your living room and avoid causing excessive fatigue of your eyes.

4K Panel Refresh Rate

The image processing frequency value determines the smoothness of the resulting image, shown in Hertz, and the 4K television ranges from 50 to 100Hz. The higher the refresh rate of the panel, the smoother the image the TV can offer you.

Tuner Type

For all types of TVs, including those with 4K support, the tuner takes care of receiving and processing TV signals. To tune into your favourite shows, you need to have a TV with a tuner that supports the same broadcasts as available with the 4K TV.

DVB-T - allows you to receive standard antenna broadcasts.
DVB-T2 - for antenna broadcasting with more efficient encoding, more data streaming and better picture quality. In 2021 it will completely replace the DVB-T standard.
DVB-S2 - together with a satellite, it provides satellite reception.
DVB-C - Allows for cable reception.
