13 Specs Before Buying A Smart TV, Smart TV Choosing Guide

Many users are confused by the wide range of products and various specifications when shopping for a smart TV, so here is a choosing guide that you can't miss before your purchase. You will know the 13 most important specs that you must understand before buying a smart TV.

1. Resolution


The image of a TV is formed by a combination of arranged pixel dots. The more and more dense the number of pixels, the more delicate and clear the image is, and the less jagged it is, which of course has to be supported by a high-resolution signal source.

FHD of 1920 x 1080 in a 65" product is already of the last era.

the vast majority of products are 3840 × 2160 4K resolution, also called UHD.

And 7680 × 4320 8K signal is not yet popular, the price is also more expensive, which is not cost-effective for now.

2. Color gamut

The color gamut value represents the TV's ability to render color, the higher the color gamut value under the same standard, the stronger the color rendering ability; at present, the TV is often said to have NTSC, DCI-P3, BT709 three standards, three standards are not common, can not be converted or directly compare their values.

3. Refresh rate

Video is formed by the continuous movement of an image, the more times the screen is updated per second, the better the video gives a sense of fluency, the number of times the screen is updated per second, we call it to refresh rate; 60Hz refresh rate is the basic standard, that is, the screen will be updated 60 times a second; 120Hz refresh rate performance is better, but also the necessary configuration for gamers, is currently a high-end product to consider a configuration.

4. HDMI 2.1 interface

HDMI 2.1 interface is able to meet the 4K 120Hz signal transmission, but also VRR variable refresh rate, ALLM low latency and other functions of the basis; but not necessarily with HDMI 2.1 interface has these two functions.

5. Quantum dot

Quantum dot is a kind of picture quality gain technology, which can improve brightness and color performance; it should be noted that not all high-end TVs will use quantum dots

6. Color accuracy

Represents the deviation value between the color displayed by the TV and the actual color, the smaller the value means the smaller the deviation.

7. Brightness

The brightness of most products can meet the needs of everyday viewing, but some professional, high-quality sources need higher brightness as support, if there is a professional viewing, gaming needs to pay attention to the brightness performance.

8. MEMC motion compensation

Between two frames with a low refresh rate, inserting supplementary frames by calculation to enhance the smoothness of the picture is a more necessary and more basic configuration.

9. Backlight partitioning

LCD TV is illuminated by the backlight to emit light, the number of backlight sources is more, and can be individually controlled, which can effectively improve the contrast, the sense of hierarchy

10. Mini led backlight

It is a further upgrade of the backlight, optimizing the traditional large lamp bead backlight into a large number of tiny, dense is ultra-small lamp beads to further enhance the brightness, uniformity, and hierarchy.

11. Memory

Like cell phones, TVs also need running memory and storage memory; running memory represents the TV's ability to run the software, and the larger the storage memory, the more software and resources can be loaded; the larger the better.

12. Processor (CPU) architecture

Also known as SOC program, currently there are several common 4 core A53, 4 core A55, 2 core A73 + 2 core A53, 4 core A73 and other programs, generally speaking, the higher the mark the stronger the processing performance.

13. OLED

OLED is the use of screen self-lighting technology, in the color gamut, contrast, response time and other aspects of the overall lead and LCD TV, OLED's disadvantage is slightly lower brightness, the stability of the product is not as good as LCD, not suitable for continuous use for a long time on. But the overall effect is better than the vast majority (95%) of LCD TVs.
