Windows 10: No Signal at Display Port

I just purchased and set up Dell U2719D dual monitors. The connection is a display port to display port to dual NVIDEA K620 video cards in a Dell Precision Tower 3620. OS is Windows 10, 64 bit with latest updates (Version 1803). All video drivers have latest updates. Computer power management is set to never turn off hard drives and monitors. When restarting windows or when powering off and restarting the computer, the monitors say no signal from display port and go into power save mode. I have to unplug new monitors, plug in older monitor (Dell U2515H) to same display port to get signal started from the display port, then I can unplug the older monitor and plug in the two new monitors and then they work fine. However, if I restart windows or power off then on, the new monotors say no signal at display port and go into power save mode.

Do you have the latest drivers installed for the graphics card?

If new drivers or reloading graphics card drivers doesn't fix it, the next thing I would suggest is to try the display port to HDMI adapter a couple of us have suggested already with a regular HDMI cable. If your cable is bad or you just need an adapter because for some reason a straight cable won't work - spending $20 on the adapter is a lot cheaper than new graphics card. I just installed my GTX 970 card a week ago and I had plenty of HDMI cables so that is why I went with the adapter instead of buying a new display port to hdmi cable.
