Many laptops still have a 1366x768 display. These should be considered 16:9, but due to the unusual width, KScreen calculates the aspect ratio as 683:384.
Similar display resolutions that should be considered 16:9, but are displayed weirdly:
- 1360x768: displayed as 85:48
- 1368x768: displayed as 57:32
STEPS TO REPRODUCE
1. Use a laptop with 1366x768 display, and/or connect a 1360/1366/1368x768 display.
2. Open Display Configuration.
Aspect ratio is listed as 683:384, 85:48, or 57:32.
Aspect raito should be listed as 16:9, even though it isn't exactly 16:9.

Prefer more common aspect ratios over correct math
Even though "43:18" or "683:384" are technically correct it's way
more common to see "21:9" and "16:9", so let's display the more
usual aspect ratios to the user.
