The most important feature that we should pay attention to when choosing the ideal TV is its display quality. Image refresh rate, screen brightness, contrast level, resolution and color clarity are the titles that are most likely to be heard when buying. If we are familiar with the types of TV image quality before choosing, we will make the best choice according to our needs in this field; So don’t miss the rest of this article!
TV picture quality
What is resolution?
Resolution is one of the most important concepts that we must know before buying. Have you ever heard, for example, that the resolution of this display is 1080 x 1920? What do these numbers mean?
Resolution refers to the number of pixels on the screen horizontally and vertically. The number 1080 represents the number of pixels on the vertical surface. 1920 is on the horizontal plane. The higher and bigger these numbers are, the better the TV image quality.
Types of TV screens
The resolution of any image largely determines its quality. Some number of pixels have become common and are known in the market by different names which we call types of TV picture quality. These qualities include SD, HD, FULL HD and 4k. But to choose which of these qualities is suitable for our needs? Stay with us:
If you’re shopping for a TV in today’s modern world, it’s unlikely that an SD quality screen is available anymore! The image resolution of this quality is 720 x 480 pixels. If you remember old DVD movies, they were made with this resolution.
If you are using an HDMI cable to watch these videos, you will not feel any change in quality reduction. But after this quality, HD was released on the market, which brought about big changes.
HD quality entered the market in 1998! At the same time, it created a lot of buzz and celebrities were very excited to see this high quality with digital sound. HD allows you to watch movies in widescreen format.
HD stands for High Definition or high quality. This type of TV image quality is exactly like its name and gives you several times better quality than normal screens. In addition to the image, the sound is also of higher quality.
The use of HD TV image quality provides the possibility of connecting to other devices such as computers. The resolution of this quality is 720 x 1280, which has 921600 pixels in each frame. If you intend to buy a television with HD image quality, you should know that the most important features that you will benefit from are: high accuracy and clarity of the image, displaying more colors, increasing the length and width of the image, multi-channel digital sound, etc.
Full HD quality
Another name for this TV image quality is the 1080 pixel format. Full HD image quality has reached its highest level and you can see even the smallest details of the image. Full HD gives you a resolution of 1920 pixels horizontally and 1080 pixels vertically.
Be careful to use this quality, you must use an HDMI cable; Because otherwise you will see a decrease in quality and basically being Full HD has no other meaning!
Another point that you should keep in mind when choosing the image quality of a Full HD TV is its aspect ratio. If you choose a TV that features a 16:9 aspect ratio, this quality will be displayed correctly and in the best way. But if the aspect ratio of your selected TV is 4:3, you lose both the quality and size of the Full HD image. The next choice is 4K TV picture quality and compared to Full HD, it is considered a masterpiece.
Currently, if you are going to buy a TV, 4k screen quality is one of the best choices you can have. In this type of technology, you will watch a much higher quality than Full HD.
The difference between 4k and Full HD is that it has more pixels in a smaller environment. The more pixels a screen has, the more clearly it will show you the details and thus the quality will increase! However, keep in mind that the pixel is not the only criterion for TV picture quality, and we will examine another factor later.
You may be wondering why it is called 4k? The reason for choosing this name is because the quality is 4 times higher than the 1080 pixel format.

What is the difference between 4K and UHD quality?
The image quality of 4k and Ultra HD or UHD are usually used interchangeably and in the market these two qualities are considered the same. These two are completely different and you should be familiar with the difference before buying.
4k displays are used in more advanced products and digital cinema, and the number of pixels is around 4096 x 2160 pixels. However, the image quality of UHD TV is specific to home shows and consumers and provides you with a quality 4 times higher than 1080 pixels. The number of pixels in Ultra HD is 3840 x 2160.
What makes the difference between these two qualities clear to me is the difference in image quality between digital cinema and home screens. Many brands use these two qualities interchangeably for greater convenience; Therefore, be careful when buying, 4k image quality is higher and more expensive.
Contrast, another factor that affects the quality of the TV image!
Choosing a TV with high image quality is the best choice. In the meantime, it is not enough to pay attention to the pixels and you should consider another criterion called contrast. Contrast ratio determines the ability to distinguish between the brightest white and the darkest black. The higher the contrast ratio of your chosen monitor, the better its quality.
Also, no matter how high the contrast of the TV is, there are no problems such as eye irritation when looking at the screen or zooming.
Contrast is a measure that is not easily obtained and must be properly evaluated; Therefore, be careful not to use the advertising aspect of this measure! In the past, the amount of contrast was between 300 and 600; But now, despite the advancement of technology, its range is between 1000 and 20 thousand.
Which TV image quality is suitable for me?
In the end, as a summary of this article, we should mention, in the end, which of the qualities is the best choice for me? These days, SD TVs no longer exist and HDs have become rare. Your choice should be between Full HD and 4K or UHD. It is you who choose between these three types according to your needs. Read the description in full and check the other aspects of the device. It should also be noted that among these three TV image qualities, 4k has a higher price.
