Display card miner link display does not respond

There are many reasons why the monitor does not display:

1. The video card is installed incorrectly, which leads to the motherboard unable to recognize the video card and the monitor unable to display. Remove the video card and refer to the installation instructions in the manual for re installation

2. The wiring of the monitor is still plugged into the main board, not the independent graphics card. In this case, you need to unplug the monitor and plug it into a stand-alone monitor

3. The power consumption of the new graphics card is large, and the original power supply can not meet its power supply, resulting in the computer can not run stably, and the display is not bright. At this time, the power supply with higher rated power needs to be replaced

graphics card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration and one of the most important accessories of the computer. As an important part of the host computer, graphics card is a kind of device to realize digital to analog conversion, which is responsible for displaying the output of graphics. The video card is connected to the main board of the computer. It converts the digital signal of computer into analog signal for display. At the same time, the graphics card also has the ability of image processing, which can help the CPU work and improve the overall running speed

< 1. The quality control of video card is very important. High quality video card should have the following characteristics: high quality components and substrate, reasonable distribution of components and circuit wiring, basic functions of the video card, excellent process quality

in order to save cost, inferior graphics cards often cut corners, save functions, and even use inferior components. Such procts often become unstable factors, such as screen, crash, etc

when choosing a graphics card, we must choose procts with reliable quality and good workmanship, which will save us a lot of time

2. Pay attention to the heat dissipation of graphics card

< P >

with the development of display chip technology, there are more and more transistors in the display chip, and the degree of integration is also higher and higher. Therefore, the heat dissipation of the chip is increasing, and the problem of heat dissipation is becoming increasingly prominent

if the quality of the cooling fan of the graphics card is not ideal, it needs to be replaced. When buying a new video card fan, it's best to take the video card with you and buy a suitable one

since most fans are fixed with spring clips or screws, we can easily remove them with a screwdriver and tweezers and pull off the power plug connected to them. When replacing, first clean the original hot silicone grease on the chip, then coat it with hot silicone grease, install a new fan, fix it as it is, and plug in the power plug

for the graphics card with heat pipe cooling, the space occupied by the graphics card is larger than that of the cooling fan, so special attention should be paid to the installation. In addition, the video storage of graphics card also needs heat dissipation. We can use self-adhesive silicone grease to adhere the fixed radiator to the existing particles

3. It is very necessary to install the appropriate driver

< P >

. The performance of the graphics card will be greatly reced if there is no driver installed

4, overclocking

some graphics cards use high-tech components, so they have excellent overclocking ability. So many players advocate the use of super frequency graphics card to improve performance. However, there must be an advantage and a disadvantage. Over locking can also lead to a significant increase in chip heat. When it reaches a certain extent, it will cause splash screen and crash. Even if not, it will be unstable in some applications, such as games, so overclocking must be moderate

First of all, disable the integrated graphics card in the BIOS, and then refresh the BIOS according to your new graphics card. Find the specific methods on the Internet. There are many. Finally, remember to connect the monitor to your unique display! Graphics card is not memory. It can't be plugged in and used

1. If there is an independent graphics card, the display must be connected to the independent graphics card interface at the back of the host computer

3. If the memory is in contact with the host, plug the memory again

1. Confirm whether the connection line of the monitor is in good condition and whether the connection line is damaged. Confirm that the HDMI cable is firmly connected, replace the HDMI cable, and confirm whether the display fault is still present

2. Open the main box, confirm whether the fan of the independent video card is working normally, check whether the independent video card is detached from the slot (except the integrated video card), then pull out the video card, wipe the metal antenna of the video card with a soft cloth, and then insert it into the slot to see whether it is normal

3. Pull out the memory from the memory slot, wipe it with a soft cloth, and then insert it again. In this step, the general computer can start normally

Computer Common Troubleshooting:

fault phenomenon: the computer indicator does not light up

in most cases, it is not caused by hardware damage, but by not pressing the corresponding key. The three indicator lights on the keyboard correspond to the three modes of the keyboard, When the corresponding key is pressed, it will light up. The keys to control the indicator light are caps lock in the main keyboard area, Num lock in the keypad area and scroll lock in the edit area (from left to right)

if the computer keyboard indicator is not on because the corresponding key is not pressed, then it may be e to other reasons. First of all, please confirm whether the computer keyboard cable has been connected with the computer motherboard interface normally, and then confirm whether the computer motherboard and interface are damaged, or whether the connecting line is broken

if all the interfaces are OK, try pressing the button corresponding to the keyboard light to see if it works, such as caps lock, NumLock, and scroll lock. If the above method fails to work, it is likely that the keyboard indicator light has been damaged. If it does not hinder the use, it is recommended to continue to use or replace the keyboard with a new one
