Samsung ViewFinity S70D
Upgraded from a 34" curved display — 37" 4K, single screen, minimal desk.
The S70D replaced a 34" curved Samsung I'd been running for a few years. The curved ultrawide was good but I kept feeling like I was managing the screen rather than using it — splitting the width into virtual halves, compensating for the curve when working with straight-edged layouts. I wanted more room without adding a second display to the mix.
The move to a single 37" 4K panel solved it cleanly. The jump from 3440×1440 to 3840×2160 is real: more vertical space for long files and browser sessions, and everything sits on one flat plane which makes the desk feel more settled. I have one cable going to the MacBook and nothing else to think about.
The appeal of one large display over two smaller ones is that it forces a cleaner way of working. With dual monitors you end up with a primary and a secondary that slowly becomes a dumping ground. With one panel, everything earns its place on screen. It's a constraint that turns out to be useful.
Colour accuracy and brightness are solid for daily work. Not a colour-grading display, but for design and development work at a desk it handles everything I need without any calibration fuss.
