When it comes to smart TVs, the higher the model, the more manufacturers tend to promote their features in a persuasive and almost hypnotic way, making consumers feel like they *must* buy. This kind of marketing can make people more passive in their decision-making. However, when purchasing a TV, it's important to have some basic knowledge so you don't end up spending too much on a product that doesn’t offer real value.
**Screen Quality: A Grade is the Minimum, A+ is Better**
The screen accounts for 50%–70% of the total cost of a TV, which makes choosing the right one extremely important. Screen quality is typically divided into three levels based on the number of defective pixels: A (up to 10 bad spots), A+ (fewer defects), and A++ (nearly perfect, often found in international markets). In China, most TVs must meet at least an A rating to be considered suitable for use. A+ screens are even better, offering a smoother and clearer display. If a seller doesn’t provide screen details, it’s worth asking them directly to ensure you’re getting a quality product.
**TV Interfaces: More and Newer Is Better**
The number and type of interfaces on a TV play a big role in its functionality. The "more and newer" approach is ideal—look for HDMI 2.0 or 2.0a ports, which support 4K resolution, and USB 3.0 instead of 2.0 for faster data transfer. These small but important specs can significantly impact your overall experience. Always check what interfaces you actually need and how up-to-date they are before making a purchase.
**Response Time: Less Is Better**
Response time refers to how quickly the screen reacts to input signals. The lower the response time, the better. For example, a 30ms response time allows for 33 frames per second, which is good for regular video playback. A 25ms response time supports 40 frames per second, which is ideal for gaming and high-quality videos. Even better is 4ms or less, which is perfect for fast-paced games and sports. When choosing a smart TV, always consider your usage needs and aim for the lowest possible response time.
**Refresh Rate: At Least 60Hz**
The refresh rate indicates how many times the screen updates per second. A higher refresh rate means smoother motion, especially during fast-moving scenes. Most 4K TVs today come with a 60Hz refresh rate, while high-end models may go up to 100Hz or 120Hz. While this is an important factor, it's not as critical as response time when it comes to reducing motion blur.
**Energy Efficiency Rating: Choose Level 1 or 2**
Energy efficiency ratings indicate how much power a TV consumes. Level 1 is the most energy-efficient, followed by Level 2. Choosing a TV with a higher energy rating might cost more upfront, but it will save you money on electricity bills in the long run and is also better for the environment.
**Input Delay: Important for Gamers**
Input delay refers to the lag between when you issue a command and when the TV responds. This is especially crucial for gamers, where even a few milliseconds can mean the difference between winning and losing. If you're into online gaming or competitive titles, look for TVs with low input delay. For casual users, the delay might be negligible, and you can choose based on other factors.
In summary, buying a smart TV involves understanding several key parameters, from screen quality and interface options to response time and energy efficiency. By being informed, you can make a smarter choice that suits your needs and budget.

Jinko solar panel, Canadian Solar panel, ja solar panel etc.all of which are among the top 10 world-renowned brands. The original A grade product is mainly mono crystalline and half cut cell solar modules, with a power range of 400watts to a maximum of 700watts.quality warranty is 25 years.
A grade, this type of film is characterized by a neat and uniform appearance, printed electrode grid lines, no broken grid, no surface stains, no leakage, no aluminum package, no hidden cracks, no scratches, no black core, no reverse current, stable electrical performance, and high conversion efficiency
Using solar cell testing equipment to measure and screen, the conversion efficiency, filling factor, and appearance that meet certain standards are first level. Generally, the conversion efficiency, filling factor, and appearance of first level are better than those of level B
The level of solar panels can be divided into first level, second level, third level, and fourth level, and the first level components can be divided into first level+and first level - two levels. The second level is also the same, and the cost difference between different levels of solar panels is also very large.
