Quick answer: To set your monitor's resolution on a Mac, open System Settings then Displays, select the display, and choose a resolution. macOS shows a row of size options from "Larger Text" to "More Space," with "Default for display" being the recommended, sharpest choice. To see every option, turn on "Show all resolutions" or Control-click for a list, which reveals native and HiDPI "looks like" resolutions. Set each screen separately in a multi-monitor setup, and pick the refresh rate from the same panel. For custom or HiDPI resolutions your monitor doesn't offer, a tool like BetterDisplay can add them. If a resolution causes a black screen, wait 15 seconds or press Escape to revert.

How to change your resolution on a Mac
Changing resolution takes a few clicks in the Displays settings. Open the Apple menu, choose System Settings, then click Displays, and select the display you want to adjust if you have more than one. In the Resolution section you'll usually see a row of thumbnails ranging from "Larger Text" on the left to "More Space" on the right; hover over each to see the pixel size, then click the one you want. On some Macs you'll instead see "Default for display" and "Scaled" buttons — click Scaled to reveal the same size options. The change applies immediately, and a brief flicker as the display re-syncs is normal. Note that macOS uses scaled rendering rather than switching the panel's true resolution, so these options change how large everything looks rather than repainting at a raw resolution. Our resolution guide explains resolution itself.
Default vs Scaled, Larger Text vs More Space
"Default for display" is the sharpest, recommended setting; the Larger Text and More Space options trade size for space. Apple picks the default to give the best balance of clarity and workspace for your screen, and it's the setting to use when you want the crispest result — on a high-resolution display it renders at full HiDPI. If the default feels too small, moving toward "Larger Text" enlarges the interface and text at the cost of screen real estate, which suits smaller laptops or tired eyes. Moving toward "More Space" shrinks everything to fit more windows on screen, ideal for coding, design, or multitasking. Bear in mind that a scaled option other than the default can slightly soften text and may affect performance, since macOS is rendering at a higher internal resolution and scaling down. For most people, Default or one step in either direction is the sweet spot. Our blurry text guide explains why some scaled modes look soft.
How to see all resolutions and HiDPI options
macOS hides most resolutions by default, but you can reveal the full list with a couple of toggles. To see the options as a list rather than thumbnails, Control-click the thumbnail view and choose Show List, or open Advanced and turn on "Show resolutions as a list." Once in list view, a "Show all resolutions" switch appears at the bottom of the Displays panel — turn it on to see every resolution your display accepts, including native pixel-for-pixel options and lower-density (non-Retina) ones that macOS normally hides. On some setups, holding the Option key while clicking Scaled reveals the same expanded list. In that list you'll notice entries described as "looks like" a resolution: these are HiDPI modes, where macOS renders internally at double the size and scales down for sharp text, so "looks like 2560×1440" on a 5K panel gives a crisp, comfortable 27-inch workspace. HiDPI options that divide evenly into the native resolution stay sharpest.
Setting resolution on more than one display
Each display has its own resolution and scaling, set independently in the same Displays panel. When you connect an external monitor, it appears as a separate item in System Settings then Displays, and selecting it shows resolution options specific to that screen — additional options often appear only once the external display is connected. So you might run your MacBook's built-in screen at "Default" while setting an external monitor to "More Space," each tuned to its size and how far away it sits. The refresh rate is set from the same panel too, via its own dropdown, for displays that support more than 60Hz. Arranging the displays and choosing which is the main screen are handled in the same Displays settings, though those are about layout rather than resolution. Setting each display to its own best resolution is the key to a comfortable multi-monitor setup. Our MacBook connection guide covers arrangement.
Custom and HiDPI resolutions with third-party tools
If macOS won't offer the resolution or HiDPI mode you want, a free or low-cost utility can unlock it. Apple Silicon Macs favor high-density displays and hide many lower-density scaling options, so a 1440p or other non-Retina monitor may not offer a sharp HiDPI mode natively. Tools fill that gap: BetterDisplay is widely used and safe, unlocking HiDPI scaling options that macOS supports but hides, without permanently modifying system files; RDM is a free menu-bar switcher for quickly picking any supported resolution; and SwitchResX adds fully custom resolutions and per-app profiles for advanced needs. These let you, for example, run a 1440p monitor in a crisper HiDPI mode. They're workarounds rather than a substitute for a genuinely high-resolution panel, but they meaningfully improve flexibility on a monitor you already own. Our Retina display guide explains why density matters.
Fixing resolution problems
If a resolution change goes wrong or an option is missing, there are quick recoveries. If you pick an unsupported resolution and the screen goes black, don't panic — wait about 15 seconds for macOS to revert automatically, or press the Escape key to return to the previous setting; if it's still stuck, restart in Safe Mode and choose a supported resolution. If the resolution or refresh rate you want is greyed out or missing, the cause is usually the cable, port, or a refresh-rate limit rather than a settings problem — a cable that can't carry the bandwidth caps your options, so use one rated for your target. On Apple Silicon, remember macOS deliberately hides some non-HiDPI modes, which is where the "Show all resolutions" toggle or a tool like BetterDisplay helps. And a brief flicker each time you change resolution is normal, not a fault. If options still won't appear, updating macOS can restore display handling after a bug.

Quick recommendation
Setting resolution on a Mac is quick once you know where to look: open System Settings then Displays, select the screen, and pick a size from Larger Text to More Space, with Default being the sharpest. To go beyond Apple's curated choices, turn on "Show all resolutions" for the full list, where HiDPI "looks like" options give you a bigger workspace while keeping text crisp. Set each display independently in a multi-monitor setup, and grab the refresh rate from the same panel. If a monitor doesn't offer the mode you want, BetterDisplay can add it, and if a resolution ever blacks out the screen, wait or press Escape to revert. The easiest path to sharp scaling at any size is a high-resolution panel like Kuycon's G27P 5K or G32X 6K, where "Default" simply looks right.
Frequently asked questions
How do I change the resolution on my Mac?
Open System Settings, then Displays, select the display, and choose a resolution. You'll see size options from "Larger Text" to "More Space," or Default and Scaled buttons — click Scaled to reveal the sizes. Hover a thumbnail to see its pixel size and click to apply. "Default for display" is the recommended, sharpest choice. The change is instant, and a brief flicker as the screen re-syncs is normal.
How do I set my external monitor's resolution on a Mac?
Connect it, then select it in System Settings then Displays and choose a resolution. The external monitor appears as its own item, with its own resolution and scaling options that you set independently of the built-in screen. Pick a size from Larger Text to More Space, or turn on "Show all resolutions" for the full list. Set the refresh rate from the same panel if the monitor supports more than 60Hz.
What is "Default for display" on a Mac?
It's the resolution Apple recommends as the best balance of sharpness and workspace. On a high-resolution display, Default renders at full HiDPI for the crispest text and UI. It's the setting to use unless you specifically want larger text or more screen space. If a scaled option ever looks soft or an app misbehaves, switching back to Default restores the recommended, sharpest result.
How do I see all resolutions on a Mac?
Control-click the thumbnails and choose Show List, then turn on "Show all resolutions." In list view, a "Show all resolutions" switch appears at the bottom of the Displays panel; enabling it reveals every resolution your display accepts, including native and lower-density options macOS hides. On some Macs, holding Option while clicking Scaled shows the expanded list too. This is how you access modes beyond Apple's curated five.
What does "looks like" resolution mean on a Mac?
It's a HiDPI mode where macOS renders at double size internally, then scales down for sharp text. A "looks like 2560×1440" option gives you the workspace of 1440p but with Retina-quality sharpness, because the interface is drawn at twice the pixels. Options that divide evenly into the native resolution look sharpest; a "looks like" value that doesn't divide evenly can appear slightly soft. It's how high-resolution displays offer comfortable sizes without losing clarity.
How do I make text bigger or smaller on my Mac?
Choose a scaled resolution toward "Larger Text" or "More Space" in Displays. In System Settings then Displays, moving toward "Larger Text" enlarges the interface and text, while "More Space" shrinks everything to fit more on screen. This changes the overall UI scale. For enlarging text in specific apps only, adjust the app's own text size or use the Accessibility zoom features instead of changing the whole resolution.
How do I set the native resolution on a Mac?
Turn on "Show all resolutions" and pick the panel's full pixel resolution, or just use Default. Native is the display's actual pixel count, shown in the full list once "Show all resolutions" is on. On a high-density display, running native pixel-for-pixel makes everything tiny, which is why macOS uses HiDPI scaling instead — so "Default for display" is usually the right choice. On a standard external monitor, native is the sharpest setting.
Why is my resolution greyed out or limited on my Mac?
Usually the cable, port, or refresh rate rather than a settings issue. A cable that can't carry the bandwidth for a resolution and refresh rate limits the options that appear, so use a cable rated for your target. Apple Silicon Macs also hide some lower-density scaling modes by design, which the "Show all resolutions" toggle or a tool like BetterDisplay can reveal. Updating macOS can also restore missing options after a display bug.
Can I set a custom resolution on a Mac?
Not natively for arbitrary values, but third-party tools add them. macOS offers a fixed set of resolutions per display, but utilities like SwitchResX create fully custom resolutions and per-app profiles, while BetterDisplay unlocks hidden HiDPI modes and RDM switches quickly between supported ones. These are useful for non-Retina monitors that lack a sharp scaling option. They're safe workarounds, though a high-resolution panel avoids the need.
How do I set different resolutions on two monitors on a Mac?
Select each display separately in Displays and set its resolution individually. Every connected screen has its own entry in System Settings then Displays, so you can run one at "Default," another at "More Space," and so on, each tuned to its size. Their resolutions, scaling, and refresh rates are all independent. Arranging them is a separate step in the same panel, but resolution is set per display.
What is HiDPI resolution on a Mac?
It's macOS rendering the interface at double the pixels for sharp, Retina-quality display. In a HiDPI (or "looks like") mode, each point on screen uses a 2×2 block of physical pixels, so text and graphics look crisp. High-resolution displays like 4K, 5K, and 6K have the pixels for clean HiDPI scaling, which is why they look so sharp on a Mac. Lower-resolution panels can struggle to offer a good HiDPI mode.
How do I change refresh rate and resolution together on a Mac?
Both are in the same Displays panel — set the resolution, then choose a refresh rate from its dropdown. In System Settings then Displays, after selecting a resolution you'll see a refresh rate menu for displays that support more than 60Hz. Pick your resolution first, then the highest stable refresh rate. If the refresh rate you want isn't listed, it usually points to the cable or port bandwidth rather than the resolution setting.
Want sharp scaling at every size? A high-resolution Kuycon panel like the G27P 5K or G32X 6K gives clean HiDPI at "Default" with no tweaking. See all 5K monitors →
