The computer display does not light up after the HDMI video capture card is installed
The problem of the computer display not lighting up after the HDMI video capture card is installed may be caused by many factors. Here are some possible reasons and solutions:
I. Check the connection
1. Monitor cable:
Make sure the HDMI cable between the monitor and the computer is properly inserted and secure.
Check whether the cable is damaged or aged, and replace it with a new one if necessary.
2. HDMI video capture card connection:
Check whether the HDMI video capture card is properly installed in the corresponding slot on the computer motherboard.
Make sure that the HDMI input port of the capture card is properly connected to the HDMI output port of the video source (such as a camera, game console, etc.).
II. Check the hardware
1. Computer host startup:
Try to disconnect all connections related to the capture card, and only keep the basic computer startup devices (such as memory, hard disk, graphics card, etc.) to see if the computer can start normally.
If the computer can start normally, it means that the problem may be related to the capture card or its connection.
2. Video capture card problem:
If the computer cannot start after connecting the capture card, try to unplug the capture card and try to start the computer again.
If the computer can start normally after unplugging the capture card, it may be that the capture card itself is faulty or incompatible with the motherboard.
3. Power supply:
Check whether the power supply is sufficient to support the newly added capture card and other devices.
If the power supply is insufficient, you may need to replace a power supply with a higher power.
III. Check the driver
1. Driver installation:
Confirm whether the correct driver has been downloaded and installed from the official website according to the capture card model and operating system version.
If the driver is not installed correctly or the version does not match, the capture card may not work properly.
2. Device Manager Check:
Go to "Control Panel" > "System" > "Hardware" > "Device Manager" and check if there are any devices related to the capture card under "Sound, Video and Game Controllers", and check if there are any yellow exclamation marks or question marks.
If there are any marks, it means that there may be problems with the driver and the driver needs to be reinstalled or updated.
IV. Other possible problems
1. Operating system compatibility:
Check if the operating system is compatible with the capture card. Some capture cards may not support certain versions of the operating system.
2. BIOS settings:
Enter the BIOS settings interface and check if there are any settings related to the PCI-E slot or video output that need to be adjusted.
V. Solution steps
1. Disconnect all non-essential connections:
Disconnect all connections except basic startup devices, such as USB devices, external hard drives, etc.
2. Reconnect the capture card:
Unplug the capture card and reinsert it into another PCI-E slot on the motherboard (if available).
3. Check the power and data cables:
Make sure all power and data cables are properly connected and not loose.
4. Restart the computer:
After completing the above steps, restart the computer and observe whether the display lights up.
5. Contact the supplier or technical support:
If the problem is still not solved, it is recommended to contact the supplier or technical support department of the capture card for further help.
