Yeah, drink the beer and coffee for now.
Just keep the advice in your head until you get some work or cash. Sell something you don't use. If you can save just $2 a day in a jar, you can get a 32" 4K monitor within a year.
I've found that one very decent primary monitor, with a secondary to the left or right that is occasionally used works best without strain. Once you have two, upgrade the main one every two years or so, moving the old main to secondary and sell the old secondary.
