morgan tell me to install amd’s driver to 2017q4 instead of now i install version 2019q2 but i’have not test yet

Have you tested driver version 2017Q4.1 yet? I've just received some information that 2019Q2 has a known bug which can lead to tearing within a display group even if you use the S400 sync board. This is planned to be fixed in the next update in 2-3 weeks. Don't know though what they might break in the update on other aspects.

can you try to connect all sending cards together with a serial USB then send RCFG files in 1 shot , usually if each sending card were programmed individually you will end up with unmatching colors or some times unmatching clock .


hope this helps
