Split it into columns, not quarters
An ultrawide adds width, not height. Quarters — the natural split on an ordinary screen — leave four short windows, only 720 pixels tall on a 34-inch panel. Columns keep every window full height, which is what most apps and sites are designed for.
- Halves give two windows of 1720 pixels each on a 34-inch ultrawide — two comfortable desktop-size windows, the easiest place to start.
- Thirds give three of about 1150 pixels: the classic ultrawide layout, and still above the width where most sites change layout.
- Two thirds and one give a main window of about 2290 pixels and a narrow side column for chat, music or notes.
- Center and sides keep your main work in front of you, with two narrow columns either side for things you glance at.
macOS’s own tiling does halves and quarters, and Fn-Control-C centers a window. For thirds, two-thirds and narrower columns you need a window manager like the free Rectangle. Every way to split a Mac screen.
Why text looks softer — and what to do about it
On a MacBook, macOS draws everything at double resolution, which is why text looks so crisp. It only does that on dense displays, and a 34-inch 3440 × 1440 ultrawide, at about 110 pixels per inch, isn’t one. It gets the standard mode instead, so text looks softer than you’re used to. Nothing is wrong; it’s how any ordinary monitor looks on a Mac.
If it bothers you, the free utility BetterDisplay can add sharper scaled modes, such as 2752 × 1152 on a 34-inch panel: everything grows a size and gets crisper, and you trade some working space for it. The other route is a denser ultrawide — 5120 × 2160 models are sharp enough for proper Retina scaling, though some owners of M4 Macs have reported macOS choosing the wrong resolution for them, so check before you buy.
Will your Mac drive it?
Every Apple silicon Mac can run a 3440 × 1440 ultrawide. The limits are about how many monitors: MacBook Air models with M1 and M2 run one external display; with M3 they run two, with the lid closed; with M4, two with the lid open. For refresh rates above 60 Hz, connect over USB-C or Thunderbolt — some Macs’ HDMI ports cap the refresh rate.
An ultrawide and a canvas
Columns are a compromise: every app gets the same share, whether it needs it or not. For the websites and web apps in your day, Tabula doesn’t make you pick a layout at all — each site is a tile on one canvas, as wide or narrow as it needs, and an ultrawide simply shows more of the canvas at once. Your arrangement is still there tomorrow. Mac apps like Finder and Xcode still want tiling. What a spatial browser is.
Questions
- Is an ultrawide monitor good for a Mac?
- For work that spreads across several windows, yes: a 34-inch ultrawide gives you two comfortable windows side by side, or three narrower ones, with no bezel in between. Text looks softer than on a MacBook’s Retina screen at the common 3440 × 1440 resolution, which is the main trade-off.
- Why does text look blurry on my ultrawide with a Mac?
- A 34-inch 3440 × 1440 monitor has about 110 pixels per inch, well short of what macOS needs to use its sharp Retina mode, so it draws text at standard resolution. It isn’t broken — it’s how any non-Retina monitor looks. A utility like BetterDisplay can add sharper scaled modes, at the cost of some working space.
- What resolution should I use on a 34-inch ultrawide?
- Its native 3440 × 1440 gives you the most room. If text is too small or too soft, a HiDPI mode such as 2752 × 1152, added with BetterDisplay, makes everything larger and sharper while leaving less space for windows.
- Can a MacBook Air run two monitors?
- It depends on the chip. M1 and M2 models drive one external display. M3 models drive two, but only with the lid closed. M4 models drive two with the lid open.
- How do I split an ultrawide into three on a Mac?
- macOS tiles in halves and quarters, not thirds, so use the free app Rectangle: choose First Third, Center Third and Last Third for three equal columns, or First Two Thirds and Last Third for one big window and one narrow one.
