1. The notebook itself must support independent direct connection. Otherwise, the image must be displayed through core display, or the interface of the notebook's external monitor must support it. For independent graphics direct connection, you just need to connect an external monitor. Check whether it is supported or ask customer service.
2. The host and display only use a VAG cable and a DVI or HDMI cable. One end is connected to the computer's integrated graphics card or independent graphics card, and the other end is connected to the VAG or DVI or HDMI socket on the monitor, and plug in Power supply, usually it can be turned on.
3. Now we see two commonly used output interfaces on various graphics cards: VGA and DVI. We need to choose the appropriate interface connection according to the situation of our own graphics card and monitor interface to ensure the display quality. . Below I will introduce these two interfaces respectively and explain how to choose the appropriate interface.
4. Of course, choose to use an HDMI cable to connect the monitor. The main reasons are as follows: VGA transmits analog signals, and the image is easily interfered, while HDMI and DVI transmit digital signals, which are basically uninterrupted. .
5. Confirm whether the monitor cable contact is intact and whether the cable is damaged. Make sure the HDMI cable is firmly connected, and replace the HDMI cable to confirm whether the monitor fault persists.
1. Confirm whether the monitor cable is in good contact and whether the cable is damaged. Make sure the HDMI cable is firmly connected, and replace the HDMI cable to confirm whether the monitor fault persists.
2. Confirm whether the monitor cable is in good contact and whether the cable is damaged. Confirm that the HDMI cable is firmly connected. Replace the HDMI cable to confirm whether the monitor fault persists.
3. Confirm whether the monitor cable contact is intact, whether the cable is damaged, confirm whether the HDMI cable is firmly connected, and replace the HDMI cable to confirm whether the monitor fault persists. Reason: There may be a problem with the HDMI cable. Check whether the TV’s signal source is HDMI.
4. If the power socket can be used normally and the wiring is good, it may be that the monitor power cord is broken and try replacing it with a different monitor power cord. If the monitor power light is on but does not display, if it is a host with a discrete graphics card, plug in the discrete graphics card again.
5. Reasons and solutions for no display when connecting the graphics card and monitor with an HDMI cable: Reason: Check that the HDMI plug of the monitor is not tightly plugged in. If the power socket can be used normally and the wiring is good, the monitor power cord may be broken and try using a different monitor power cord.

4. It may not be set properly. The adjustment method is as follows: Step 1: Check whether the HDMI plug of the monitor is plugged in tightly. Once plugged in, the signal detection button will appear. Step 2: If the power supply and socket can be used normally and the wiring is good, the monitor power cord may be broken and try using a different monitor power cord.
There are three types of connection cables between the graphics card and the monitor, namely: HDMI cable, VGA cable, and DVI cable. There are cables connecting the graphics card to the monitor; the interfaces include DVI interface, VGA interface, and HDMI interface.
It’s called VGA cable. The VGA cable is a cable used to connect the host computer to a display device that supports the VGA interface. The VGA interface is used to output analog signals on the graphics card. The VGA (Video Graphics Array) interface is also called the d-sub interface. Although LCD monitors can directly receive digital signals, many low-end products use VGA interfaces to match VGA interface cards.
Video line. The most commonly used one is the VGA cable. But as for HIMI DVI, it depends on your graphics card interface.
HDMI cable can be used to transmit audio signals and video signals without any compression. Mainly used in video and audio signal transmission of PCs, high-definition players, LCD TVs, rear projection TVs, and projector display devices.
The above is the detailed content of Graphics card and monitor cable. For more information, please follow other related articles on the PHP Chinese website!
