Upgraded from a 1080Ti to a 4070Ti, computer no longer displays all monitors

Hello, any help would be greatly appreciated.

It seems like what's happening is I'm at the GPU's limit, but I don't think I should be. I have one monitor always greyed out in the display settings or nvidia control panel. I can disconnect one of the other monitors, to then extend to that one. I've found other people with the same issue and it was usually due to the GPU's limit (the 4070Ti as I understand it can handle pushing 8k at 60hz). My setup is:

1 3840x2160x144hz (DP)

1 1920x1080x60hz (DP to HDMI)

1 1600x900x60hz (DP to DVI)

1 800x480x60hz (HDMI)

Which should mean I'm well within the limit, however the only thing that seems to make my pc display to all monitors, is changing my main monitor from 144 to 120hz. So it's like my computer thinks it's over the limit with 144hz when it shouldn't be. I'm also using a Corsair LS100 for the ambient lighting around the main monitor, is that also taking up the gpu (I don't think so because I turned it off and still had the issue)? I always assumed the software for that just looked at the colors already on the screen. Or maybe there's too many variations in connection type, resolution, refresh rate? I did try swapping the 900p monitor for another 1080p with a DP so it wasn't using the DP to DVI cable and had the same resolution as my other monitor, but still had the same issue.

No idea why I can't display all 4 at once when it seems like the GPU should be more than capable. Any advice would be a huge help, thank you!
