How to get 60 FPS 2560x1440 resolution on AOC U2868 in macOS

I wrote this one line script because I was unable to put my AOC monitor back into 60 frames per second mode after enabling 4k.

macOS display preferences make dang near impossible to achieve. First just type in cscreen at the terminal to get the ID of your monitor, in my case 78ca19c6:

cscreen
DisplayID Index Depth Width Height Refresh
78ca19c6 1 32 2560 1440 60
use -h to display all usage options
➜ ~

Then issue the command again, this time with the monitor unique ID and the parameters:

cscreen -d 32 -x 2560 -y 1440 -r 60 -i 78ca19c6
➜ ~

Swap 78ca19c6 for the value of your own monitor.

This will give you the best 60 FPS display performance AFAIk, the resolution known as 2560 x 1440 (QHD/WQHD - Wide Quad High Definition)

Idea: National, Regional and Amateur Hackathon Teams

Here is a cool idea that could be supported either by government or big business.

Similar to sports teams, a series of leagues are setup, by way of a series of Hackathons in each major city, with the initial outcome of the first match being a regional team of 10 winners for each region or city, say $10,000 each.

The next year, do the same thing again, this time generating a 'Regional B Team'. About a month or two later the regional teams could do battle in a remote nationwide Hackathon, to create the national team. The All Green Screens / Call Blacks / All Black Hats or similar. In the time between the matches, the teams and their manager may be able to promote a couple of players from 'Regional B' by swapping an existing player with the new one. Likewise the 'Regional B Team' would have some chance to swap out a couple of players for amateurs who did well in the regional heats.

In the third year, it goes international, by way of the internet, no actual stadium is required. The regional heats are the only Hackathons that have a physical presence. This is because of an interesting trend in Hackathons worldwide.

The national team is encouraged to play in global Hackathons, which we'd own if we are allowed to compete as a team not as individuals:
