GPU:  Sapphire Radeon HD6790 - 1G - GDDR5 - PCI-e

CPU:  Intel Core i7 9000 series/8th gen.

MB:    MSI Z390 - Gaming Plus-intelZ390 chipset

MEM:  Corsair - DDR4 - 2666 - 32gb

MONITOR:  ViewSonic 24” Digital/DVI

NO SIGNAL on display!  I can hear everything else running but absolutely no signal!   Swapped out cable to new and ditto. I can use the motherboard integrated DVI, but not the Radeon!

I placed the card in my older computer and it works beautifully on the same monitor?


i have to believe that maybe it’s the timing required for  the DDR4 is not valid for the GDDR5?  Am I following the wrong path here?
