Select brand
When selecting smart TVs, remember that you should not blindly select and choose. Compared to the arbitrarily chosen TV brand, choosing a larger, harder brand is more secure in both product quality and service.
size
The comfort zone of the eye is 60 degrees. In theory, knowing the distance of the glasses to watch the screen, you can know the best screen size to buy. When the distance is actually 3 meters, the size is over 100. Taking into account people's watching television habits and the market's popularity screen size, the following recommendations for the smallest size.
Resolution
Everyone knows that the resolution of the human eye is limited and can only be a small degree. If the point is the smallest, it cannot be resolved. There is no difference between watching 240p and 1080p video in the distance, but 240p cannot be tolerated if it is viewed at close range. The choice of resolution is mainly determined by the screen size and viewing distance.
Screen color
First of all, to correct the two misunderstandings, the first one, the screen color can not just look at the panel, not because the "original LG screen" "original Korean panel" to think how good its quality, and how high-end. Secondly, we know that Taiwan, Japan and South Korea are the main regions for producing high-end panels, but they also produce low-end panels. Therefore, the quality of the screen cannot be determined by factions and regions. In fact, some domestic panels are also good. It depends on the integrated visual performance of IC design, imaging, and so on. Screen colors mainly look at the screen layering and solid color lighting. In general, TV malls will play video and movies in a unified way. We can compare the distribution of shadows and bright spots in the screen. The finer the screen, the better the screen. In addition, we can observe the screen's leaks and lighting conditions in a relatively dark environment. A good screen is basically the same brightness in the center and around. In addition to looking at the light, we must also observe whether there are yellow, reddish, and pan-blue color defects.
In most cases, the speakers of the TV can meet the daily audio-visual needs. When listening to sounds, the volume should be turned up, and attention should be paid to the characters and background sounds. In addition, try not to choose ultra-thin TV because the speaker needs space to express the sound, and the thickness of the ultra-thin TV limits the speaker. Of course, with an external stereo is also possible.
CPU, GPU, memory, storage, etc.: The CPU (central processing unit) is the core of a smart device. The quality of the device depends on the quality of the CPU: GPU (graphics processor): The picture is good or bad Memory: If you compare the CPU to the masher, the memory is the feed port. Storage: save the photos, audio, and video recordings.
Application extensions:
The first thing to do after TV starts is to log in to the sofa butler to find an installation tutorial matching the TV to install the sofa butler to implement third-party application extensions.
