How to do if the display does not show
-
compatibility problems (to ensure that your graphics card is damaged, it is recommended that you plug in more memory, clear the BIOS, and plug in more graphics cards)
-
power supply problem, PC power supply is not big, there is no way to supply independent graphics card, so it is not bright
-
the graphics card is broken or there is a problem with the graphics slot
-
some old motherboards will appear the kind of situation mentioned above, which needs to be shielded
-
installing an independent graphics card on the motherboard will automatically shield the output of the integrated graphics card, which is the default output of the independent graphics card
-
if the independent graphics card does not light up, check whether the power supply of the graphics card is normal. It is not recommended to use the VGA interface for the middle and high-end graphics card, and there will be no signal< br />
some graphics cards need external power supply. Confirm whether there is a problem with the external power supply
the motherboard is not possible, or there is a problem with the compatibility of the graphics card itself
please accept if you are satisfied
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
extended data:
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
This is very important for professional graphic designers. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's top 500 computers contain graphics computing cores. In scientific computing, graphics card is called display accelerator card
< 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
