I want to change to a computer LCD monitor, have some questions? Thank you

There is no such display as "Runjing", I guess you are talking about "Runjing LCD display", right? In fact, this "moisturizing eyes" is just a gimmick of merchants. The radiation of the LCD itself is lower than the CRT display, there are thousands of LCD display models of various prices and grades on the market, and the price of 2000 yuan is mostly the low-end 22-inch or high-end 19-inch products of the mainstream brand, and the specific choice of what brand and what model depends on your economic affordability and specific needs.

Brands I personally recommend include Samsung, AOC, and ViewSonic but you'll have to look for yourself in the market.

The things to pay attention to when buying are not something that can be explained in one or two sentences, just like selling everything, shopping around, looking more and asking more is the right way.

There's nothing to say about matching,Just choose a common monitor with VGA and DVI dual interfaces,It will definitely match your graphics card,Don't worry about this。

Graphics cards generally have nothing to do with LCD, LCD mainly looks at the panel, you better choose to be made by your own company, not OEM.

Runjing display is essentially a liquid crystal display, there is no big difference. Personally, I recommend you to buy mainstream LCD monitors. Personally, I feel that Samsung's display is good.

It can be replaced, but there are many places to consider, and it is best to take pictures before dismantling and make a record to facilitate installation.

It depends on the size of the driven screen, the size of the screen is different, the parameters of the lamp are different, and the power supply voltage of the high-voltage board required is also different. If the power is sufficient, if the power supply of the high-voltage board is 12V, the small size of the screen (below 26 inches) may be possible. For screens above 26 inches, most of the high-voltage power supply is 24V, and the number of lamps ranges from a dozen to more than 30.

Considering the need for energy saving, the power difference between the normal operation and standby of the current LCD TV is very large, and the power supply circuit is designed with an active PFC correction circuit. The power supply has a main power supply part and a secondary power supply (standby power supply) part. The main power supply does not work when the TV is standby, and the standby power supply will always work as long as it is powered on.

Whether the main power supply works or not is controlled by the boot circuit of the driver board.

Large-size LCD TVs not only need 12V, 24V, but also 18V (audio circuit) and other voltages when working, and the power supply power requires more than 100W, and the power of ordinary LCD power panels cannot meet this requirement. And the power supply part of LCD TV generally uses multiple chips. Some circuit structures are not ordinary switching power supplies, but their excitation half-bridge circuits.

The computer boot screen is like this, and there is still a problem with changing the monitor.

Causes and solutions to the blurred screen of the computer: 1. The blurred screen caused by the increase in the temperature of the computer graphics card. Workaround:

Check whether the fan is running normally, add lubricating oil to the fan, clean up the dust in the chassis, and solve the heat dissipation problem. 2. The solution caused by the graphics card or monitor not supporting high resolution: (1) Restart the computer, press the F8 key continuously, jump out of the advanced boot menu, select enter to enter the "safe mode" to log in to the system, and then enter the display settings under Windows, select the 16-color state, click the "Apply" button, and click the "OK" button; (2) Restart the computer, in Windows normal mode, enter the device manager, delete the graphics card driver, and restart the computer; (3) The graphics card is loose, and unplugging the graphics card and re-installing it after shutting down usually solves the problem; (4) If the system is overheated, including the CPU temperature is too high and the graphics card chip temperature is too high, you can install a cooling fan in the chassis, or place the chassis in a well-ventilated and round place.

1) It can be changed to a different model of display, 2) it was LCD before, it can be changed to an LCD model, 3) it can also be changed to a CRT type, 4) but, after changing the monitor, you need to readjust the resolution, 5) Set the resolution steps: Start - > the control panel - > display - > settings, in the settings interface, find the "screen resolution" item, the resolution setting, according to the size of the screen itself, and whether the text on the screen is suitable for your own eye comfort, and finally "OK", As shown in the figure below.

It doesn't affect at all, if the size of the display is different, the resolution is OK when you set it.

Yes, the monitor has nothing to do with the files stored on the computer itself, and you can just replace it. However, it is necessary to pay attention to the resolution issue.

Yes, you can change it directly, but it should be noted that if the resolution of the monitor you change is lower than the original, it will prompt that there is no signal input, so it is best to change the resolution to the same as the original (of course, if it is different, you can adjust it in the system).
