Black screen after chosing C&C or Red alert

This is my exact problem.  I've been through the EA Support live chat three times (Case #61400489), trying all the various workarounds they suggested:

Thanks for the reference, but nothing in that thread helped to fix my issue.  I am using Steam on Windows 10 and I tried messing with all my Nvidia settings, but I'm still unable to load up the game at all.  I have a GTX 2070 with up-to-date drivers, plus an SSD.  This is so depressing.

Are you sure you aren't getting a popup from Windows 10 firewall requesting access to the network be granted?  I got the black screen  until I alt+tab and saw the popup.  I hit OK and it works fine.

The black screen locks up my PC; alt+tab, Ctrl+alt+del, alt+f4 don't do anything. I have to restart every time. I do hear the opening video sounds and main menu music (I think), but just a black screen and unresponsive PC.

Problem solved......I just turn MSI Afterburner off......

I've seen that suggestion elsewhere, but I don't have MSI afterburner installed. I don't overclock my video card or otherwise monitor/control it with any third party software. Glad to hear you got your game working, though, congrats!

Ok I'm a *. It was a simple resolution problem, as countless other people have mentioned in other  threads. I had to resolve it from within the Nvidia control panel. The black screen was just the lower resolution game on my high resolution screen. I tried fixing this before with the conquer.ini file but that didn't work for me.

Game works fine for me now. I don't deserve to be a PC gamer...

I just changed the resolution setting in my Nvidia control panel to be lower, 1920x1080. I guess it must override the regular Windows setting. Once I did that I did not have the black screen anymore. Then in the game I changed the resolution to 4k, then went back to the Nvidia control panel and changed that back to 4k too. Now I can play it in 4k.
