When assembling a computer, choosing the right monitor is crucial. A high-quality monitor can greatly enhance your computer experience. PHP editor Youzi will carefully discuss the selection criteria of monitors today, including screen size, resolution, panel type, refresh rate, interface, etc. Through this article, we will help you understand how to choose the best monitor for you based on your needs and budget.
Computer accessories are composed of several major categories, and then subdivided into specific models corresponding to specific uses.
For example, monitors are subdivided into many types according to different uses and parameters.
You have to look at the purpose of the computer you choose to assemble. If it is gaming/design processing/image and audio-visual processing, then you need to consider the size and refresh frequency. If it is for general household use, just choose the ordinary one.
"Only the person who wears the shoes knows whether they fit or not." This sentence is also suitable for assembling computers. Only you know your needs and can choose the one that suits you based on your needs.
1500 yuan, it is a bit difficult to buy an assembly machine plus a monitor at this price. If you really want to assemble it, I will be speechless. The result will definitely make you speechless and regret it. I still recommend that you buy an original one. It’s cheap and comes with a warranty. I suggest you go to a local professional department that sells original machines, such as Shenzhou and Founder. I don’t need to explain these things.
Generally, there are several reasons why the monitor has no signal hardware.
1. The memory is loose (key point)
If the memory is not plugged in properly, the monitor will have no signal input and needs to be reset. When plugging or unplugging, if the motherboard is not plugged in at all, it will alarm. Check whether the gold finger of the memory module is burned.
2. The graphics card is not inserted properly.
Re-insert and unplug. Same as above.
3. The monitor or monitor signal cable is loose and damaged.
Re-insert the signal cable. To be sure, you can try on another computer to see if there is a signal on the monitor and signal cable
4, the motherboard is broken
You need to try the host on another computer and check the motherboard Is there any burnt capacitor?
This is because the vga line connecting the host and the monitor is loose, and I don’t know which port is not connected securely. As a result, the signal cannot be uploaded from the host to the monitor
1. Split the monitor, separate the monitor screen, monitor tray, and monitor power supply;
2. Find a box that is larger than the monitor, and find a few foam strips;
3. First lay a layer of foam on the bottom of the box;
4. Face the front of the monitor to the foam and place it flat;
5. Then put the monitor tray, power supply and other parts Put it into the box;
6. After checking and placing all the disassembled parts, put another layer of foam on top; then pack it into the box and seal it with transparent glue.
After the new computer is assembled, there is no signal on the monitor when it is turned on. You can check to see if it is due to the following reasons:
1. Is the power turned on? If the power is turned on, check to see if it is the power supply of the monitor. Not plugged in properly
2. Check whether the VGA or HDMI cable is plugged in properly. Some computers have two graphics cards, try changing the socket
3. Is the monitor switch turned on
If the above checks are done, there will generally be no problem.
The difference is mainly reflected in the following aspects:
1. Component type: The monitor is an output device used to display images and text generated by the computer host. The host is the core component of the computer, including the central processing unit, memory, hard disk, etc.
2. Function: The monitor is mainly responsible for displaying images and text, with resolution, brightness, contrast and other parameters. The host is responsible for calculating and processing data, and running various software and applications.
3. Connection method: The monitor is usually connected to the host through a video cable (such as HDMI, VGA, DisplayPort, etc.) to receive the image signal sent by the host. The host is connected to the monitor through power cables and data cables (such as SATA, USB, etc.).
4. Installation location: The monitor is usually placed on the desktop for users to watch. The host can be placed on the desktop or placed in a chassis, usually on the ground or under the table.
5. Assembly difficulty: Relatively speaking, assembling the monitor is relatively simple. You only need to install the monitor base and connect the power and video cables. Assembling a host requires more steps, including selecting and installing various hardware components, connecting power and data cables, installing the operating system, etc.
In general, the monitor and the host are two important components of the computer system, each with different functions and installation methods. The monitor is mainly responsible for displaying images, while the host computer is responsible for calculating and processing data.
The host is running normally but the computer screen shows no signal: Solution:
1. First check whether the host power supply is properly connected, whether the fan of the power supply is rotating, and whether the power indicator light and hard disk indicator light on the host panel are flashing. Because if the host power supply is not working or the motherboard is not powered, and the monitor does not receive a signal, of course there will be no image display.
2. Check whether the power supply of the monitor is well connected. If the power switch of your monitor is a touch switch, you should hear a slight "pop" sound when you power on the monitor. At this time, it can be judged that the switching power supply circuit of the display is good.
It won’t work if you plug in another monitor. Whose computer is so arrogant? The possibility of it breaking after just replacing it is very small. The host can run the graphics card and there is no physical damage. It is probably a connection problem.
Try changing the cable. Nowadays, most homes have TV boxes provided by broadband. , the box will come with an HDMI cable, which can be replaced with the computer one.
If it still doesn’t work, check to see if the position of the HDMI interface and the chassis baffle are deviated, causing the HDMI cable card to not be plugged in tightly. This problem often occurs on mid- to low-end chassis. It is a workmanship problem of the chassis. It may be You need to pull the graphics card hard (or use an angle grinder to enlarge the space at the chassis bezel) before plugging in the cable.
You can also check the monitor. This is simple. Just connect it to the TV box. Just like
The reason why the computer monitor does not light up and the solution:
If the monitor is not plugged in with the power cord or VGA cable, it will naturally not light up. The two wires are the first we want to check. Also note that the other end of the VGA cable is connected to the host, and check whether it is plugged in properly.
The reason why many computer monitors do not light up is that the memory module has poor contact or the memory module is damaged. We only need to open the case and check whether the memory module is inserted properly. If there is still no response after plugging in the monitor, then the memory module may be damaged. Take it to a computer store to have it checked.
It is also possible that there is a problem with the motherboard. Let’s clean the dust on the motherboard, then remove the battery button on the motherboard and remove the static electricity before putting it back on. Then plug in the power and try restarting.
If your computer has a discrete graphics card, then there may be something wrong with the discrete graphics card. First, unplug the discrete graphics card, clean the golden finger part of the independent graphics card, and also clean the graphics card slot. Plug it back in again.
A broken monitor is of course the last thing we want to encounter. Although it is unlikely, it is inevitable. In this case, the only option is to take it for repair or directly replace the monitor.
The display (display) is also often called a monitor. The monitor is an I/O device of the computer, that is, an input and output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device and then reflects them to the human eye. According to different manufacturing materials, it can be divided into: cathode ray tube display (CRT), plasma display PDP, liquid crystal display LCD and so on.
