If you're desperate for a more-square monitor, Eizo has made a true square (1920x1920, equal to 2560x1440) monitor for some years now, the EV2730Q (https://www.eizo.com/products/flexscan/ev2730q/ https://www.eizo.com/products/flexscan/ev2730q/) I think its pixel density is around 140 pixels/inch, so the retina folks won't like it, but if you value real estate over sharpness, you can use all of the available pixels without scaling. (It'll even do 2048x2048, but the scaling makes everything a bit blurry.) Emacs is amazing. The EV2730Q runs $1429 in December 2021; if this new LG monitor can be had for that or less, it could be a big success. EDIT: Scratch that, square monitors will never be more than a niche, enthusiast product, so "big success" is wrong. But maybe, having LG behind it, it'll make more people aware of the choice. Now, for the counterpoint: Dell makes a 43-inch 4K monitor, the U4320Q (https://www.dell.com/en-us/work/shop/dell-ultrasharp-43-4k-usb-c-monitor-u4320q/apd/210-avke/monitors-monitor-accessories https://www.dell.com/en-us/work/shop/dell-ultrasharp-43-4k-u...). The prices vary over time, but for $959 as I write this, you get essentially two EV2730Q monitors mounted side-by-side. A better deal, but it's a huge monitor, way too big for my tiny setup. And I keep hearing complaints that a monitor that large requires more head movement to see everything. Edit: I have to say, I'm surprised that LG would venture into monitors like this. I had despaired that Eizo would be the only one willing to make a niche product like a square monitor, but I'm glad to see LG doing so, and making a higher-resolution one to boot.
