When evaluating digital devices, there is a really important parameter: resolution. But quickly improvements in the range of resolutions have been so fast that buyers cannot distinguish them.
The difference between 4K, 8K and 1080p
The main difference between 4K and 8K lies in the number of pixels (pixels) calculated in resolution. 4K has 3840 pixels and 8K with 7680 pixels. Because vertical resolution also doubled, 8K has 4 times more pixels of 4K. The following is a 4K, 8K and 1080P comparison table.
| Resolution | 4K | 8k | 1080p |
|---|---|---|---|
| Pixel horizontal*vertical | 3840*2160 | 7680*4320 | 1920*1080 |
| Total number of pixels | 8,294,400 | 33,177,600 | 2.073,600 |

Should choose 4K or 8K resolution?
Digital devices today offer a variety of resolution options. For better image quality and vivid details for TVs, printers, cameras and other devices, consumers are confused between 4K and 8K resolutions. The best choice for you can depend on the type of device you are buying. Here are some instructions.
For TV
The 8K resolution was first launched for the TV. Famous brands such as Samsung, LG and Sony all sell 8K TVs, but is 8k suitable for you? The following are the factors you need to consider.
- Image quality: You may think that the higher resolution automatically means better image quality, but that is not necessarily true. The difference in the number of pixels sounds impressive, but the person's eyes are almost not noticeable. Only when the 8K TV is greater than 65 inches, the image quality of 8K is really appreciated.
- Compatible content: 4K TV can display countless compatible programs and content, but that is still not true for 8K. Currently, the only 8K content is being produced as records and broadcasting programs that test such big events and the World Cup finals, but they are not free for the public.
- OLED or QLED: TV screen technology can affect your choice. OLED stands for “Organic Light-Emitting Diode”, TV technology is most commonly used, while QLED means “Quantum-Dot Light-Emitting Diode”. This type of screen uses quantum dots to enhance the color display of TV. Most 4K TVs use OLED, while 8K TVs often use QLED.
- Expense: Although there are many 8K products on the market, they are still much more expensive than the confirmed 4K models (the average price is higher than the 4K OLED TV from 3,000 to 5,000 USD, too high for most people. consumption).
For gaming
The resolution and image quality are very important for gaming players, but the resolution of most games is still Full HD 1080p, largely because the lower resolution will not cost too many bandwidth. Playing 4K games is still not available for all games and all systems, but PlayStation 5 and Xbox Series X are announced to be 8K. The latest gaming devices of Sony and Microsoft will also support 8K content, including electronic games, but have not been released.
For cameras
Security camera manufacturers know that consumers want to have higher resolutions and higher accuracy, but currently there are very few 8K cameras. When buying high -resolution security cameras, consider the following.
- Image quality: The resolution of security cameras determines the image quality of the camera. The higher the resolution, the better the camera can provide image quality and with more pixels in an image. 8K security camera will definitely bring more clarity and detail than 4K security cameras.
- Storage and consume bandwidth: There is an old champ that every coin has two sides, and that is true when considering the benefits of different high -resolution cameras. The higher the resolution, the more they need the storage space and take up more bandwidth. 4K security camera needs 10-80MB storage capacity per minute and takes at least 25 mBS bandwidth in a minute. The storage and bandwidth requirements of 8K security cameras may be twice as much as the needs of 4K.
For resin printers
For 3D, 4K and 8K resin printers used to measure the resolution of the liquid crystal screen (LCD screen). The higher the LCD screen resolution, the more detailed printing models will provide. For more density and details, the 8K resin printer will be better than 4K but will need more printing and expensive time.
