I believe this ONLY works with resolutions above 1920x1080
No it depends on a combination of screen size and resolution.
for example small screens with a 1366x768 resolution will show it. a laptop with a 15 inch screen and this resolution will however not show it.
The trick however is that on a small screen this setting allows you to have 4 rows of tiles. On a small 10/11 inch screen however, you only have 3 rows by default and the setting lets you have 4 rows like the bigger screen.
so basically if you don't have the setting active, it's useless to you, as it will only let you reduce the number of rows to smaller screen setting.
