Mac Pro after restart black screen

[MattDSLR]

Hello All

I try to find this but lately found an issue with my baby MP

after I restart it and do a fresh start sometimes I get a black screen until I press a power button again and then it comes to life like it was asleep.

I do get a start up sound and than a black screen press a power button and everything is OK

But this only happens only some time

Any help will be good

Thank you

Dodgy cable is probably not sending the correct signals sometimes.

Try get a different cable from your Mac Pro to your monitor(s).

Will try but what does the power button has to do with it?
