Hello, the price of a display screen with the same screen size is generally reflected in the differences in resolution, response time, lumens and so on. Of course, the price of the same size screen produced by different manufacturers also depends on the manufacturing cost and market price positioning. Generally speaking, you get what you pay for, but the display screen, as a relatively mature technology, can meet the needs in general household and office use, so the cost performance is an aspect worthy of attention. I hope the above will help you. Good luck!
What is the difference between a monitor and a monitor?
The display screen is a single screen, and the display is a complete machine, including a shell, a power supply, a driving board and a display screen.
What's the difference between liquid crystal and non-liquid crystal?
There are two kinds of LCD and CRT, which are the earliest head displays. Generally speaking, if used improperly, it will cause harm to eyes, but CRT is relatively much larger. You must be a liquid crystal, but what kind of liquid crystal is another matter. There are many kinds of liquid crystals now: TFTLEDIPS: TFT refers to TFTThinFilmTransistor, which means various liquid crystal images. Pixels are driven by thin film transistors integrated behind the pixels, and these transistors are actively driven. Now a corresponding method is that the display is passively driven for a long time. At present, TFT-LCD with higher resolution is basically used, but it consumes more power. Besides, LED backlight is because LCD display is a non-active display technology, that is to say, the LCD panel is just an optical switch, which controls the switch of each pixel to display images. There must be an optical switch behind it. To use a surface light source to emit light, this surface light source is called backlight. Generally, there are two kinds of light sources: FCCL cold cathode tube and LED, and LED backlight is the light source of LED, which is relatively energy-saving. IPS is a patent of all-angle technology, which was originally a patent of Hitachi. Now LG and Chi Mei both have patents. Relatively speaking, the deviation of the liquid crystal in the panel is different, thus achieving the result of expanding the viewing angle, that is, facing the display device. From a broader perspective, the color of the display has not changed. IPS technology has obvious advantages: if the viewing angle is wider and there is no obvious color change when pressing the screen, it will also lead to an increase in energy consumption and a decrease in light transmittance. Being a TV application is an advantage, but as a mobile phone computer, IPS has no advantage to view the original post >>

What's the difference between a computer monitor and an led TV?
Can be considered from the following aspects:
If you try to connect a computer host to an LCD TV. You will find that the displayed picture will be very gorgeous, and the color cast will be absolutely serious. The biggest culprit for this problem lies in the gamma adjustment. The default standard gray value of computer monitor is 2.2. Although it is difficult for consumer monitors to be completely accurate, the mainstream products on the market will not differ much. The PC host also sets the signal output to suit the gamma value of 2.2. In this way, we can see the accurate (or nearly accurate) color representation through the display. It's ok to watch movies on LCD TV, but it's hard to be perfect when dealing with documents and browsing the web. Its words are vague and its edges and corners are not sharp. Although the screen is big enough, it looks as hard. There are two main reasons for this phenomenon. The first problem is the LCD panel.
There is a great difference between resolution points. At present, the mainstream resolutions of LCD TVs are 1366*768 and 1920* 1080. Even a 55-inch TV has only 1920* 1080. The resolution of LCD is much higher. 2 1.5 inch widescreen resolution is 1920* 1080, and mainstream 22 inch resolution is 1680* 1050. It can be seen that the resolution of the same size screen is much higher than that of LCD TV. Take 30-inch LCD monitors and 32-inch LCD TVs with similar screen sizes as examples. The resolution of 30-inch LCD is 2560* 1600, and the dot pitch is 0.254; The mainstream 32-inch LCD TV is 1366*768, and the pitch is 0.5 185mm. The size difference is only 2 inches, and the difference between the horizontal/vertical value of the resolution and the point distance is about twice.
The optimization direction of IC driver is different, "low-end products look at the panel and high-end products look at the driver", which shows how important the problem of driver optimization is. The same panel, different driver optimization, the display effect gap is worlds apart. The reason why professional monitor manufacturers are so powerful is not how strong the panel advantage is, but the optimization technology accumulated over the years, which makes it difficult for competitors to compete.
Television as a monitor is seriously harmful to vision. LCD TV is the first choice because of its large size. When users face TV at close range (such as games), they need to constantly change their visual focus. However, the brightness distribution of LCD TV is not uniform. Although the user can't notice it, the eyes are constantly adapting to various brightness, which naturally increases the burden and is easy to get tired.
Gray loss varies greatly. Generally speaking, a point that people can see with naked eyes on the LCD screen, that is, a pixel, is composed of three sub-pixels: red, green and blue (RGB). The light source behind each sub-pixel can display different brightness levels. Gray scale represents the level of different brightness from the darkest to the brightest. The more intermediate levels, the more delicate the picture effect can be presented. Take the 8bit panel as an example, it can represent the 8th power of 2, which is equal to 256 brightness levels, so it is called 256 gray scale. Each pixel on the LCD screen is composed of red, green and blue with different brightness levels, and finally forms different color points. That is to say, the color change of every point on the screen is actually caused by the gray level change of the three RGB sub-pixels that make up this point. The above analysis is a bit complicated. If you can't understand, you just need to understand that if a computer wants to display accurate colors, it must have all gray levels of 0-255. The loss of gray scale means the loss of color. For PC host, the output gray scale is 0-255. When the gray output is 0, a full black screen is displayed; When the gray scale is 255, a full white screen is displayed. In order to adapt to the PC host, the acceptable gray signal range of LCD is also 0-255.
What's the difference between computer monitor LED and LCD? Which is better?
Please understand that the screen is divided into: backlight and glass, that is to say, glass is constant. If glass and LCD tube are used as backlight, it is LCD screen; If the backlight is glass and high-brightness energy-saving patch lamp, it is a standard LED screen.
Note: LED backlight is composed of many small patch lights, just like our clothes zipper, with many small raised buttons strung together.
Personally, I think it is good for LCD. When the LCD lamp is broken, it is easy to change, and the color temperature and contrast are good, while when the LED is broken, it is not easy to change, but the brightness is high and the power is low, and the color temperature and contrast are not so good.
Good contrast, black picture should be very black, white picture should be very white. You can understand this problem by playing a high-definition video. Video usually doesn't show up and down, so it should be very dark.
What's the difference between LCD and ordinary computer monitors?
No matter how professional the liquid crystal is, it can't compare with the professional CRT display, so don't consider the liquid crystal when drawing. Although the relevant parameters of professional LED liquid crystal have been improved many times than before, the most important color reproduction degree is still not enough! ! And sometimes the color difference is very large.
What's the difference between a flat screen TV and a computer monitor? 5 points
1, it is certainly possible to use a large flat-screen TV as a monitor (I mean, there is no technical problem at all), but what do you want with such a large "monitor"? It's good to watch movies and TV, but it's not practical and too big for daily office use; Moreover, the resolution of flat-panel TV is currently 1920× 1080. If it is to be used for professional drawing, it is definitely not applicable. You might as well buy a smaller high-resolution monitor.
2. At present, the difference between flat-panel TV and LCD is definitely due to the sound effect (LCD with speaker is rare, even if there is, the sound is not good), the display effect (color reproduction, whether there is smear, etc. ), and the resolution (TV is generally 1920× 1080, while the display is higher, which is more suitable for precise drawing, etc. Also, you should consider factors such as beauty and mobility.
I almost never use my 46-inch TV for work or surfing the Internet, but only for watching movies, which is really cool.
4. consider that what suits your needs is the best.
What's the difference between HD LCD and other ordinary LCDs?
These three models are indeed HD monitors that support 1080P.
But in fact, under such a small size, the practical significance of HD is not great.
Moreover, when playing online games, the display effect of 16: 9 is obviously worse than that of 16: 10. The screen is too flat, and the browsed page is too flat. Some games don't support this resolution, even if they can, the consumption of your graphics card resources is huge and meaningless.
Therefore, individuals still prefer to choose the 22-inch display screen of 1680* 1050. If there is a demand for high definition, it is also recommended to choose a monitor with a resolution of 1920* 1200 or above.
What's the difference between a good monitor and a bad monitor?
I don't think it is necessary to change it. The main performance of the display actually consists of two aspects:
1, LCD panel. The former or more common is TN panel, which is cheap, but the color gamut, viewing angle and gray level are relatively general. The high-end ones are IPS, PAV and so on. Among them IPS is the best!
2, IC chip, even if a manufacturer uses a good panel, but its own research and development ability is not strong, it will not play the maximum rent of the panel. IC chip is the program to control the work of LCD. This is equally important.
So don't just pursue panels or brands when buying LCD monitors. For example, Samsung's monitor, the high-end is really strong, but the low-end also uses TN panel, and the display effect is actually no different from that made in China. On the contrary, it is a good domestic panel, but the price is similar to that of Samsung. It's better to buy domestic ones.
Finally, according to your situation, there is no need to buy a new monitor. You're just playing a game. This monitor is enough. People who want a good display are generally high interior design, PS and the like. In fact, people with high color requirements will not buy LCD. Because CRT display has the inherent advantage of displaying any color, and the color of even the best LCD display is limited.

Why is LCD TV so expensive? It is expensive to watch TV;
A computer monitor needs a set-top box to watch TV. If this' set-top box' is in the display, the display becomes a TV set. If the sizes are equal, this is the difference, right?
