Question New GPU, no signal to monitor

[Treestriker]

Hello,
Just got a new GPU (MSI GTX 1660 super, upgrading from Radeon 570). I uninstalled all the old drivers, unplugged them put in the new GPU. Turned on the PC and the monitor is saying no signal or input although the GPU is running and such.
Any help or suggestions would be appreciated.
