Not true. Monitors now are 1440p or 4k. Even at work for me.
The "issue" is that monitors last a LONG time. And thats good. We dont touch them or fiddle with them. They tend to just work. Phones and shit we keep dropping and breaking, then the battery gets bad.
Also for gaming you may even want 1080p 200hz monitor for high refresh rate and FPS over pixel density.
