Q5：The large screen of the video card directly connected with the sending card
is displayed normally, and the screen will appear black screen when it is connected
to the video processor.
A:
Observe whether the sending card indicates that the green light flashes normally. If the signal
is given by the processor's output port, the possible reasons are as follows:
①
The problem of signal source. When connecting the computer graphics card, the copy
mode of the graphics card should be set. If not, the DVI port of the graphics card has no data
output. Setup steps: Turn off the power supply of video processor - reinsert the line from video
card to video processor - ATI graphics card reads and replicates automatically. NVIDIA graphics
card needs to enter the graphics card control center and set up multiple d double screen
replicate mode.
②
Connection problems. When the signal line interface contacts badly or there is a
problem inside the wire, the large screen will appear abnormal phenomena such as color stripes,
flower screens and so on. Check carefully whether the pin in the signal line is broken or inclined
and change the signal line.
