Samsung Odyssey Neo G9 57 on a Mac: resolution, scaling and window layouts
By Guido Crego · Last updated:
The 57-inch Neo G9 has no USB-C, so a Mac connects over HDMI or a USB-C-to-DisplayPort cable. Full 7680 × 2160 takes a Mac on Apple's 8K list, which covers most Macs with an HDMI port made since 2023, and owners report 120 Hz. The catch is scaling: macOS offers native, with small text, or a sharp mode that looks like 3840 × 1080, where everything is huge.
| Size | 57" |
| Resolution | 7680 × 2160 (32:9) |
| Column widths at 7680 × 2160 | ½ 3840 · ⅓ 2560 · ¼ 1920 |
| Column widths at 3840 × 1080 | ½ 1920 · ⅓ 1280 · ¼ 960 |
This page is about the 57-inch Odyssey Neo G9 (G95NC, from 2023): 7680 × 2160, 32:9, rated up to 240 Hz (Samsung spec sheet). The 49-inch G9s, the 49-inch Neo G9 included, are 5120 × 1440 screens with their own page. Same shape, but the 57-inch has 50% more pixels across and a denser panel (about 140 pixels per inch against 109). Everything here was checked on October 8, 2026; reports from owners say so and link to the thread.
The cable: HDMI or DisplayPort, no USB-C
The 57-inch has one DisplayPort 2.1 input, three HDMI 2.1 inputs and a USB hub. No USB-C port at all, so it can’t charge a MacBook and there’s no one-cable USB-C desk. Two ways in:
- HDMI, from a Mac with an HDMI port. For 7680 × 2160, Apple asks for “an Ultra High Speed 48 Gbps HDMI cable” and says “adapters aren’t supported for these resolutions and refresh rates” (Apple). Plug it straight into the Mac, not into a dock or a USB-C-to-HDMI adapter.
- A USB-C-to-DisplayPort cable into the monitor’s DisplayPort 2.1 input. One M4 Max owner runs full resolution at 120 Hz this way, over a DP80 cable (BetterDisplay, 2024).
Which Mac gets what
Apple’s 8K-over-HDMI list is the best guide to full resolution. Owner reports fill in the refresh rate:
| Mac | What you get | Source |
|---|---|---|
| On Apple’s 8K list: MacBook Pro with M2 Pro or Max, M3 Pro or Max, or any M4 or M5; Mac mini with M2 Pro, M4 or M4 Pro (and newer ones listed); Mac Studio from 2023; Mac Pro 2023 | 7680 × 2160 over the Mac’s HDMI port, with a 48 Gbps cable and no adapter | Apple |
| MacBook Pro M3 Pro | 7680 × 2160 at 120 Hz with HDR, over HDMI | Apple Community, 2024 |
| Mac Studio M4 Max | 7680 × 2160 at 120 Hz, over an Ultra High Speed HDMI cable | BetterDisplay, 2025 |
| M4 Max | 7680 × 2160 at 120 Hz over USB-C-to-DisplayPort (DP80), with compression (DSC) | BetterDisplay, 2024 |
| MacBook Pro M1 Pro or Max | 5120 × 1440 on one cable (120 Hz in one report); full resolution only with picture-by-picture over two USB-C-to-HDMI cables, at 60 Hz | Apple Community, 2023 · BetterDisplay, 2025 |
| MacBook Air, or a base M1, M2 or M3 | Not on Apple’s 8K list, and we haven’t found an owner report |
The monitor is rated for 240 Hz, but we haven’t found a Mac owner reporting 240 Hz at 7680 × 2160, so plan on 120. If the picture flickers, turn off Adaptive Sync, Apple’s fix for variable refresh (Apple). One owner’s flicker stopped with a fixed 120 Hz instead of the 48 to 120 Hz VRR range (BetterDisplay, 2025).
Scaling: tiny, huge or soft
macOS’s sharp “looks like” modes draw everything at twice the size and scale it down (BetterDisplay wiki), and Pro and Max chips top out at a 7680-pixel-wide image (BetterDisplay wiki). One owner found the M4 Max still capped there (BetterDisplay, 2024). On this screen that leaves a Pro or Max chip two sharp choices (we haven’t seen a report from a base M4 or M5):
- Native 7680 × 2160, at 1×. About 140 pixels per inch, so text is clearly smaller than on a 27-inch 1440p monitor (about 109). An M4 Max owner calls it “super clear but tiny to the point that it’s not really viable for apps without their own scaling features” (BetterDisplay, 2025).
- Looks like 3840 × 1080, an exact 2×. Very sharp, but menus, toolbars and text get big: “hugely oversized”, in the words of BetterDisplay’s developer (2023).
Everything in between, 5120 × 1440 included, is LoDPI: macOS draws it at 1× and stretches it to fit, so it looks soft. The same M4 Max owner called 5120 × 1440 “the Goldilocks of scaling”, but “without a HiDPI version, everything just looks fuzzy by comparison”. A sharp 5120 × 1440 would need a 10240-pixel-wide image, and as BetterDisplay’s developer puts it, “Sadly no Macs support 8K+ resolutions natively” (2026).
Two workarounds owners use:
- A BetterDisplay virtual screen. Turn on resolutions over 8K, create a virtual 32:9 screen and mirror it to the monitor. An M3 Max owner runs it as a sharp “looks like 6016 × 1692” at 120 Hz with HDR (BetterDisplay, 2025). The cost: refresh sometimes falls back to 60 Hz or VRR, and another owner gave up on it because of lag (2026, same thread).
- Picture-by-picture. Two cables, two 3840 × 2160 halves that macOS treats as two displays, each with its own HiDPI mode. That’s where the lag owner ended up. It needs a Mac that drives two displays.
All of this predates macOS 27 (September 2026), which brought “higher resolutions on ultrawide displays” (Apple). We haven’t seen a report that it changes anything on this monitor.
Common problems
- Full resolution drops to 5120 × 1440 after sleep. Reported on a Mac mini M2 Pro and a Mac Studio over HDMI (Apple Community, 2023). Owners’ fixes: a USB-C-to-DisplayPort 2.1 (40 Gbps) cable, which brought back full resolution on every wake (that owner saw some flicker at first); switching the monitor’s HDMI version setting from 2.0+ to 1.4 and back when it happens; or picture-by-picture.
- 120 Hz disappears, leaving 60 Hz or VRR. With a BetterDisplay virtual screen, owners stop the mirroring, pick 120 Hz in System Settings → Displays and mirror again; if only 60 Hz or VRR is offered, they restart first (BetterDisplay, 2025).
- 7680 × 2160 isn’t in the list. In System Settings → Displays → Advanced, turn on “Show resolutions as list”, then “Show all resolutions” (Apple).
- No sound. macOS lists the monitor as an audio output, but it has no speakers (Apple Community, 2024).
Samsung’s own app: Easy Setting Box
Samsung’s support page for the 57-inch lists Easy Setting Box for macOS (version 3.1.6, March 2025), next to firmware 1008.2 from September 2025 (Samsung). Samsung describes Easy Setting Box as splitting the screen “into various layouts of multiple sections”, but that page says Windows only (Samsung), and we couldn’t confirm what the Mac version does on this monitor. If the installer won’t open, owners suggest Open Anyway (Apple Community, 2025).
Shoji · window zones for Mac works with any brand, so the MacBook’s screen and a monitor from another maker get zones too. You draw the zones yourself, right on the screen, any size and overlapping if you want. And each monitor keeps its own layouts: Shoji recognizes the 57-inch by its hardware and brings them back when you plug it in again.
Splitting 7680 × 2160 into windows
macOS tiles windows into halves and quarters only (Apple), and half of this screen is 3840 points: a whole 4K desktop for one window. Columns make more sense. The table at the top has the widths; at native resolution:
- Thirds give each window 2560 points, what a whole 27-inch 1440p monitor fits across, and taller.
- Four columns give 1920 points each, the width of a 1080p screen.
- A wide center with narrow sides (25 / 50 / 25 means 1920 / 3840 / 1920) keeps the window you work in straight in front of you.
- A chat, a wide center, a preview and a stacked column, the layout in the demo above: the right column holds two small windows, like a terminal over notes.
At “looks like 3840 × 1080”, the same splits give 1280 points per third and 960 per quarter. At 5120 × 1440 (LoDPI, or the M1 Pro and Max’s limit), the math is the 49-inch G9’s, on its page. For layouts on other ultrawides, see ultrawide monitors on a Mac.
Set it up with Shoji
Shoji · window zones for Mac lets you draw these layouts and snap windows into them.
- Open Shoji and allow Accessibility when macOS asks. Any app needs it to move other apps’ windows.
- From the Shoji menu in the menu bar, choose Edit Zones and pick the Neo G9.
- Start from Thirds or Center + sides, or drag on the screen to draw your own zones. They snap to a 12 × 8 grid, so thirds land on 4 / 4 / 4 twelfths, four columns on 3 / 3 / 3 / 3 and a wide center on 3 / 6 / 3.
- Save. Hold fn while you drag a window: the zones light up. Let go over one and the window fills it.
The 57-inch keeps its own layouts. If it sits next to a MacBook, the laptop screen has its own zones, and when you unplug the monitor its layouts wait for it until you plug it in again.
Questions
Does the Samsung 57-inch Neo G9 work with a MacBook Pro?
Yes. With an M2 Pro or Max, an M3 Pro or Max, or any M4 or M5 chip, it drives 7680 × 2160 over its HDMI port, and owners report 120 Hz. An M1 Pro or Max gets 5120 × 1440 on one cable, or full resolution with picture-by-picture over two. A base M3 isn’t on Apple’s 8K list.
Will a Mac mini or Mac Studio run the 57-inch Neo G9 at full resolution?
Yes, if it’s on Apple’s 8K list: a Mac mini with an M2 Pro, M4 or M4 Pro, or any Mac Studio from 2023 on. Use its HDMI port and a 48 Gbps cable. One M4 Max Mac Studio owner reports 120 Hz. The base M2 Mac mini isn’t on the list.
Does the Neo G9 57 run at 240 Hz on a Mac?
Not that we’ve seen. The monitor is rated for 240 Hz, but the Mac reports we found at 7680 × 2160 top out at 120 Hz.
Why can’t I get a sharp 5120 × 1440 on the G95NC?
A sharp 5120 × 1440 needs a 10240-pixel-wide image, and Macs top out at 7680. macOS offers it only as LoDPI, which looks soft. The sharp choices are native 7680 × 2160, looks like 3840 × 1080, or a BetterDisplay virtual screen.
Can the 57-inch Neo G9 charge my MacBook?
No. It has no USB-C port at all, so keep the Mac’s charger plugged in.
