A 1080p display in 2023 is just sad. It lacks image quality and it’s more blurry.
The rest of your post is fine but this but is just untrue. You’ll find a huge portion of the laptop market is still 1080p and it’s perfectly okay, it’s FHD.
For laptops (which generally have a smaller screen than desktop monitors), the pixel density is still good at 1080p.
Sure, you’d notice a difference if you tried to go from 1440p back to 1080p. And there’s other factors like contrast and colour for the display. But 1080p in 2023 is not sad.
You can use any laptop with any usb keyboard if that helps. If you already have a laptop, it’ll be much cheaper to buy and you can get a full mechanical keyboard that suits you.
