Using 390 drivers with fresh cards ("GeForce RTX 2080 SUPER"???) is pointless as old drivers do not recognize "device ID" of your card and just assume the worst (hence 1024x768 as from their perspective this resolution should be supported on anything) as the alternative is no graphics at all.
Use the most fresh 440.44 version. If it is not available from the get-go, add additional unofficial repositories, download rpm or deb files manually from some site like "pkgs.org", do any other magic necessary… Install the drivers manually from the nVidia site directly, if you must (don't listen to any "Gurus" out there telling you it is not right -- your PC, your rules)! But make the card work. Otherwise, it will be wasteful usage of (the most expensive) part of the system; you'd better get some Intel or AMD APU and use integrated solution. At least, the electricity bills would be smaller. :)
