[2020] new 4k monitor makes apex not launch.

Hey, if you wipe your local Apex settings file -which will be trying to set your resolution when you start- does that change anything?

If you go to C:\Users\yourusername\Saved Games\Respawn\Apex\local you'll find a videoconfig.txt file. 

If you delete this, then start the game, it should do a quick check and then recreate the files with settings for your system. 

If this has no impact, you can open the videoconfig file with Notepad and change "setting.fullscreen" "1" to "setting.fullscreen" "0"

That should launch the game in a smaller window, then once you're in the game itself you can mess around with the available screen settings. 

Good stuff, thanks for the update.
