As the current mainstream video capture card, some users report that there is no image on the HDMI capture card during use. For this problem, Ninevision has organized a solution to share with you, so that everyone can easily solve the problem of no image on the HDMI capture card The problem.


When using an HDMI capture card without an image, it is like turning on the computer display and it does not light up for several reasons. as follows:
1. Problems with the video cable First, the HDMI capture card has no image connected to the video source. We need to check if the HDMI video cable is good. Whether the video source can output video signals normally. If the video cannot be output to the display device, then you should check whether there is any problem with the video source interface and whether the replaced HDMI cable can solve it.

2.The acquisition device has HDCP encryption
HDMI output to the display device is good, but there is no image on the capture card, then you need to confirm whether your device has HDCP encryption function, and the capture card does not have HDCP decryption function. This is often a big reason that some capture cards cannot output signals.

3. After setting the acquisition software, after confirming the above two points, also confirm whether there is any problem in the setting of the acquisition software, because some software does not have the preview function checked by default. After opening the software, you need to check it yourself. For example, you need to check the preview option in AMCAP before the image appears. Some software is also very important to select the standard when collecting SD signals. It must be set to match the standard of the video source signal. For example, in the potplayer, select the country in the TV ---- system -----. The image will only appear if the correct format is selected.

4. Output resolution There are some HDMI capture cards. The output resolution does not reach the required resolution, and the performance of the capture card can support it. What is going on here? Because the resolution of some cards when designing is to match the resolution of the video source, that is, what is the output, how much can the video source be set.

5. Chip problems Avoid hot plugging of the HDMI interface to burn out the chip. Some customers often unplug the cables on the HDM capture card and keep power off when using it. Digital signal transmission is current-carrying. In this way, plugging and unplugging under power may break the chip. As a result, the capture card has no image.

If the image cannot be displayed after the above problems are eliminated, it is recommended to directly call Jiushi Electronic Technology: 400-061-8657
