Why does graphics quality decrease?

Q:  Why does graphics quality decrease when VGA signal is transmitted by input and output interface of the hybrid matrix?                                        

First, hybrid matrix VGA input is for converting analog signal to digital signal, and then to analog signal VGA output. Since the signal has been converted twice, it must decrease to some extent, so does the graphics quality.

Second, hybrid matrix supports multi-signal format output and input. So analog signal transmission after conversion will be not a patch on the direct signal transmission. We suggest that you try to use HD signal input of the hybrid matrix, such as HDMI input + HDMI output, VGA input + HDMI output, and so on, instead of VGA input + VGA output.
