Can't get display signal on new build

When I turn on my PC, it tells me "No HDMI signal from device." This occurs when plugged into my mobo HDMI port and the HDMI port on the GPU. This is a custom build, and has never booted before. When examining I found I may have a bent pin in the mobo socket, could this be the cause? Everything powers up fine and lights up when turned on (fans, GPU, AIO, etc.), but for some reason I can't get an HDMI signal on either of my monitors with any of the ports.
