Totals, panels only
| 34" ultrawide | Two 24" Full HD | |
|---|---|---|
| Total width | 31.5 in (80.1 cm) | 42.4 in (107.8 cm) |
| Height | 13.2 in (33.5 cm) | 11.8 in (29.9 cm) |
| Workspace | 3440 × 1440 | 3840 × 1080 across two |
| Megapixels | 5.0 MP | 4.1 MP |
| Screen area | 416 in² | 492 in² |
| Pixel density | 109 PPI | 92 PPI per panel |
The dual total includes a 0.6 in pair of touching center bezels; real stands and frames add a little more.
What each layout is actually for
The ultrawide's argument is the middle of your view: one unbroken picture where the dual setup puts its bezel seam, which is exactly where a game, a film, or a wide timeline wants to sit. One cable, one stand, and full-screen apps that span the whole width.
The dual pair's argument is structure: two physically separate screens snap work into clean halves, one can turn portrait for code or documents, the panels can be bought one at a time, and a broken screen is half the loss. If your day is two windows side by side, the seam sits in the gutter between them and costs nothing.

Common questions
Is one 34-inch ultrawide better than two 24-inch 1080p monitors?
They solve different problems. The ultrawide gives one seamless 31.5 in (80.1 cm) picture; the pair gives 42.4 in (107.8 cm) of total width and 4.1 megapixels with a bezel seam in the middle. Immersion and full-width apps favor the ultrawide; split, structured work favors the pair.
How wide is a 34-inch ultrawide monitor compared to two 24-inch 1080p monitors?
The 34-inch ultrawide panel is 31.5 in (80.1 cm) wide. Two 24-inch 1080p panels side by side span about 42.4 in (107.8 cm) including touching bezels, so the pair takes more desk width.

How these measurements are calculated
For a diagonal d and aspect ratio w:h, screen width is d × w / √(w² + h²), and height is d × h / √(w² + h²). Area is width × height; PPI is √(horizontal pixels² + vertical pixels²) / diagonal in inches. Results are rounded for display.
Screen dimensions exclude the frame, feet and stand. Check the manufacturer's measurements for furniture and mounting clearance. A flat-screen viewing angle is 2 × atan(width / (2 × eye-to-screen distance)). The 40° cinema target is a preference, not a requirement; adjust the viewing angle for your room. It is approximately equivalent, for a 16:9 screen, to the distance × 0.835 sizing rule in the THX viewing guide.
The 60 central pixels-per-degree reference is a rule of thumb, not a guarantee that two displays look identical. Eyesight, contrast, source quality and panel technology also matter. Check sharpness at your own viewing distance.
