Monitorture34″ 3440×1440: Flat vs 1900R vs 1800R vs 1500R vs 1000R vs 800R
Same panel — same 34″ diagonal, same 3440×1440 grid — bent to different radii. A monitor's R number is the radius, in millimetres, of the circle the screen is a slice of: a smaller number is a tighter curve. Here's this panel from above at Flat vs 1900R vs 1800R vs 1500R vs 1000R vs 800R, drawn to scale.
| Curve | Curve depth | Screen wrap | Ideal distance | Best for |
|---|---|---|---|---|
| Flat | — | — | — | Straight lines stay straight — best for CAD, layout & print |
| 1900R | 42 mm | 24° | 1.90 m | Moderate — immersive, with a slight bow on long straight edges |
| 1800R | 44 mm | 25° | 1.80 m | Moderate — immersive, with a slight bow on long straight edges |
| 1500R | 53 mm | 30° | 1.50 m | Moderate — immersive, with a slight bow on long straight edges |
| 1000R | 78 mm | 46° | 1.00 m | Aggressive — strong wrap; straight lines visibly bow |
| 800R | 97 mm | 57° | 0.80 m | Very aggressive — maximum immersion; not for precision layout |
Which curve should you pick?
The radius doubles as the ideal viewing distance: sit about that far away and every point of the screen is the same distance from your eyes, so nothing at the edges needs re-focusing. The 800R version wants you at ~0.80 m — while the flat panel is happy at any distance.
The catch is that a curve bends every straight line. For films, games and a wraparound feel a tighter radius wins. For work built on straight edges and exact geometry — documents, spreadsheets, CAD, photo and layout — a bowed horizon is distracting, so a flatter panel (or none) reads truer. Match the curve to whichever you do most, then sit near its ideal distance.
