1. I'm not afraid of not knowing the goods. I'm most afraid of comparing the goods. Generally, the counters of the businesses selling laptops have the laptops that have been started for consumers to try. Before purchasing, we can carefully compare the display quality of the LCD on the counter. It is better to compare the LCD of different brands or different series of laptops of the same brand, mainly comparing the color saturation and brightness, We can set two (or more) laptops' LCDs to the brightest, and then open some colorful pictures (such as fruit platter) at the same time. This is the most direct and effective way to judge the display effect of different LCDs. However, businesses may not have too many notebooks/

How to choose LCD display and how to know the performance of LCD?

before purchasing, we can carefully compare the display quality of LCD prototype on the counter. It's better to compare the LCD of different brands or different series of laptops of the same brand, mainly comparing the color saturation and brightness, We can set two (or more) laptop LCDs to the brightest, and then open some colorful pictures (such as fruit platter) at the same time. This is the most direct and effective way to judge the display effect of different LCDs. However, since businesses may not have too many notebook prototypes on the counter, this method should be timely.

2? For LCD,
each pixel is composed of three units, which are respectively responsible for red, green and blue display, For example, the XGA screen needs about 2.4 million units  1024x768x3=2359296.
therefore, it is difficult to ensure that all these units are intact during transportation.
some units with short circuit will become "bright spots"
while those with open circuit will become "black spots"
we can identify the number of bad points through special software (such as Nokia monitor test).
A Generally speaking, it's normal to have one or two bad points on a new machine. You can't expect to buy a perfect LCD display, as long as it doesn't affect the display effect (generally, it's normal to have a bad point below 5. Different manufacturers have different regulations on how many bad points are substandard products), LCD display with bad points may not be poor in other aspects (such as saturation and brightness).

3. Is the viewing angle "broad"? When we look at the LCD from the side.
Although the light can penetrate the correct pixels, the slanted light will also penetrate the adjacent pixels, so we will find the problem of serious color distortion. The angle that does not cause color distortion is called the "viewing angle" of LCD. For the identification of viewing angles of different notebook LCDs, we can directly see the pictures on notebook LCDs from different angles, Generally speaking, the bigger the viewing angle, the better the effect and the higher the price of LCD.

4. Response time.
if you plan to use your notebook to play some games (such as the first person shooting game) with very fast picture updates, the response speed of LCD becomes a key factor, Unlike ordinary LCDs, notebook LCDs usually do not indicate the response speed, so we can run large FPS games to directly feel whether the "tailing" phenomenon is serious. Of course, it's better to compare different notebook LCDs, and there is no obvious delay when playing, If there is no dizziness, it can be judged that the LCD can play FPS games.

monitor.
the main parameters are as follows: 1: contrast. Generally, Samsung and LG are at the forefront of such products, with tens of thousands of contrast, and the price is not cheap.
2: gray response time: generally 5ns.
the high-end point is 2ns, Such products are more than 1600.
now 17 inch standard screen is very rare in the market.
most of them are 19 inch wide screen.
Life 22, 24 and other High-size displays.
if you buy 17 inch now.
it's estimated that TPV will be able to buy products like Acer.
specific parameters.
under the premise of close price, which one has higher parameters,That's the one.
