Could you please elaborate on why you think you passed out or what led up to that incident? Whenever I'm particularly stressed, I tend to become very light-headed or dizzy to the point where it feels like I'm about to pass out, but I never do. I've had this on and off for years. I'm only 26 years old.
Usually it is the way of breathing that changes, because of anxiety (fight or flight state). The pace and volume becomes imbalanced with respect to the oxygen / co2 needed, even when no hyperventilating seems to be happening. This imbalance causes lightheadedness and ultimately dizzyness or passing out.
One trick that can help, when you feel like that, breathe in deeply and the breathe out very very slowly through a fine opening between the lips. Then pause several seconds and repeat. This can be done without anyone noticing, because it is subtle and slow.
I have the same thing, one weird connection I realized was: coffee. Apart from the stress of being a solopreneur, I noticed whenever I had coffee, I ended up being anxious/panicky later in the day.
It might be placebo, but since I stopped drinking coffee, I rarely have those intense feelings of anxiety.
I do have personal experience, at least in following the advice of that blog post. After reading it, I bought the Dell S2722DZ which is 27" 2560x1440 for 108PPI. It's a decent monitor and I haven't had any issues with scaling, i.e. the "native resolution" of the monitor works with the output of the OS and there's no need to waste CPU/RAM on scaling the pixels. The text isn't as crisp as on a Retina, but it's way better than the previous cheapo monitor I had.
Not sure my opinion counts for much though, since I didn't try any monitor in "the red zone" and thus have nothing to compare it to.
This Dell model does have a 1px column of dead (?) pixels that appears sometimes, but if I squeeze it then it goes away. I think it's due to some loose wire in the paneling... but it's not too big of a deal, and regardless, it's unrelated to PPI or scaling or whatever.
Developing software for small, independent cinemas is a notable idea. While I can't speak for the global situation, based on my experience in Europe, many cinemas suffer from outdated and subpar booking software. Creating an aesthetically pleasing platform akin to Shopify for webshops could prove to be a lucrative endeavour. My research into existing solutions revealed a dearth of options, and the few available ones look crap.

I used to use Obsidian with iCloud sync between my Mac and iPhone. However, I found iCloud sync to be too unreliable, and Obsidian Sync was beyond my budget.
After recently exploring alternatives, I have now chosen Ulysses with Ulysses sync (taking advantage of a student discount at 11 USD/6 months). I write all my notes in Markdown and organize them exclusively within folders and subfolders, without using links and tags. This setup suits me perfectly.
