I do understand the part about eyesight, but don't you agree that one should use a resolution that fits the screen (not be stretched more on one axis than the other to cover the screen)?
Some resolutions that fit a 16:9 screen are:
1280x720 ▬ 80 * (16, 9)
1408x792 ▬ 88 * (16, 9)
1536x864 ▬ 96 * (16, 9)
1664x936 ▬ 104 * (16, 9)
1792x1008 ▬ 112 * (16, 9)
1920x1080 ▬ 120 * (16, 9)
And there are many in between those too.
I'm not saying SO needs to use 1920x1080, there are many alternatives that are good, I'm saying its incomprehensible to me that he insist on using a 4:3 resolution on a 16:9 sized screen.
1024x768 ▬ 256 * (4, 3) when he could use:
1360x765 ▬ 85 * (16, 9) or
1376x774 ▬ 86 * (16, 9) to get a picture that is not distorted such that everything is wider than what its supposed to be.
If a resolution I have listed is not possible to select in-game then it is fully possible to set a custom resolution in the civIV .ini file that will work.
