First, please confirm that there is no problem of the monitors and outputs, the graphics driver is stable. And then, please check the connection of the HDMI cable whether it could satisfy with the version of monitors and outputs.
All of above is ok, the splash screen and video corruption are likely due to HDMI cable’s signal attenuation or insufficient bandwidth on the network. So please replace old one into a new HDMI cable. If the question is still happen after changing new cable, please try to change the monitor to find out what happen.
Please contact vcomnet@vcom.hk to get professional advising, if the question is still couldn’t be solved.
