Question Can't get second monitor to work

May 8, 2021
I have the Following
EVGA GeForce RTX 2080 Ti DirectX 12 11G-P4-2281-KR 11GB 352-Bit GDDR6 PCI Express 3.0 HDCP Ready SLI Support BLACK ...
ASUS ROG Strix X470-F Gaming AM4 AMD X470 SATA 6Gb/s ATX AMD Motherboard
AMD Ryzen 7 2700X 8-Core 3.7 GHz (4.3 GHz Max Boost) Socket AM4 105W YD270XBGAFBOX Desktop Processor
I think that is the relevant items. But just as the title says I bought a second monitor today and I can not get Windows to detect it. The GPU only has 1 HDMI slot so the second HDMI is going into my MB. Seen some other post about enabling the Onboard GPU but when I go into the Bios there is no visable option to as several youtube videos suggest I go to. The second display brand new samsung 32 4k something or other and my main display is a samsung 32 4k curved something or other. Trying to use HDMI on both. Looked at Bios configurations and setups but they seem to have options I don't have in Bios setup.

Any help would be appreciated,
thanks friends.
Ps you guys help a lot of people that are less inclined like myself, much appreciated.
