Recently, I've been getting back into game like SimCity (2013) and SimCity 4 (2003) [found on EA/Origin and Steam, respectively], having fun building up cities and looking forward to large skyscrapers filling the skyline, keeping my Sims happy as they churn through their little lives... Looking through a SimCity forum, while I was reading up a bit about Omega (which is 'new to me') I came across someone posting a Thread asking about 'how to run SimCity 4 in 1920x1080' resolution. I saw some replies from other helpful people, but oddly, none of the options/command-lines worked [as of the time of this posting], with typed-in options such as "-w" (for running in Windowed Mode) and so on... Wanting to help, I went experimenting in Steam's SimCity 4 that I owned and looked a bit more online about other possible solutions as well - and I eventually found out what works, as of today! Here is what worked for me:

• In Steam, where SimCity 4 is listed in your game Library, Right-Click on the game name and Select (Left-Click) Properties.
• In the center section, click on the button labelled "Set Launch Options...". This adds commands to the game that would be 'typed in and utilized', if the game was run in that type of interface.
• In the box of Launch Options, type (or copy-paste) the following into the area:
  
  
  -CustomResolution:enabled -r1920x1080x32
  
  
  [be sure to include the hyphens and have only one space between the two commands]
  
• Click on OK to close that panel, then click Close to close the Properties of the game in Steam

That's it! 

Running the game (and after the Introduction Cinematic/Movies play [if you have not disabled them] as they are rendered and play in a fixed resolution), you should find the territory/region screen gloriously taking up all of your screen space... Here is what it will look like:

Example of SimCity 4 (Steam version shown) running in Widescreen (16:9 Aspect Ratio) Mode in Windows 10,
after following the steps shown above [other steps found online did not work for me personally]

Have fun building up your Sim City! 

[Don't forget to take lots of Screenshots! heh]
