When you say "incorrect resolution" what do you mean? What happens when you select a resolution from the options screen?

Oops, I toyed around some more and found out that the issue is actually slightly different:

• Sound correctly plays if the game begins in windowed mode, but sound vanishes if the game ever enters full-screen at any time (even if you revert back to windowed mode) during that particular session
  
• It gave me a higher resolution option than what my TV was capable of; that's what I had gotten confused by. When restarting the game at a TV-appropriate resolution (3840×2160), it presents itself correctly, but the text is so small that it's too hard to play.

Sound is fixed via windowed mode, but is there ever gonna be an option to be able to increase the global font size? Thanks for your fast response!

There's an option to scale the entire game UI. Look in the "GAME" options screen.

Ohh, crud, lol. So that's what that was! It works perfectly when windowed to the full resolution and with the UI scale at something like 60% to the right.

I suppose maybe a one-time note about the UI-scale option, when going out to massive resolutions might help. Anyway, great game. I had caught some typos in the text and would be happy to send them over if there is any practical probability of them getting fixed.

I tried again and unfortunately while the UI is now fine, the marines and everything else are still way too small to play on the big screen. It's too bad that the maximum zoom limit can't be adjusted because that's the one thing that would solve this issue, like UI Scale.

Try turning the "World Maximum Detail" in the graphics options to the maximum.

It will use more video ram, but it will also increase how far you can zoom by 2.
