Features
Per-display zoom
Remember a preferred zoom for each monitor by display ID.
|
Per-window isolation
Changing zoom in one window does not affect others (requires window.zoomPerWindow).
|
Automatic switching
Move a window to another display and Smart Zoom applies that display’s saved zoom.
|
Also included: status bar menu, learned display profiles, and support for macOS, Windows, and Linux (X11).
Requirements
Required: "window.zoomPerWindow": true (VS Code default). Smart Zoom applies zoom per window and will warn if this setting is disabled.

Getting Started
- Install Smart Zoom from the marketplace (or install a VSIX).
- Confirm
"window.zoomPerWindow": true in your settings.
- Move a window onto a display, then click Smart Zoom in the status bar and choose a zoom level.

Settings
Most users only need the status bar menu. These settings are available under Smart Zoom:
| Setting |
Default |
Description |
smartZoom.enabled |
true |
Enable or disable Smart Zoom |
smartZoom.pollInterval |
500 |
How often (ms) to check which display the window is on when watch mode is unavailable (for example Windows / Linux polling). Higher values use less CPU. |
smartZoom.defaultZoom |
0 |
Zoom level used when no profile or rule matches (0 ≈ 100%) |
Zoom levels are VS Code integer window zoom levels (approximately ±20% steps: 0 → 100%, 1 → 120%, -1 → 83%, …).
Advanced settings & zoom resolution
| Setting |
Default |
Description |
smartZoom.stabilityChecks |
2 |
Consecutive stable readings required before applying a display change (reduces flicker while straddling monitors) |
smartZoom.displayProfiles |
{} |
Learned per-display profiles (usually managed by the UI) |
smartZoom.zoomRules |
[] |
Optional rules keyed by resolution + scale factor (usually managed by the UI) |
When a window settles on a display, Smart Zoom picks a zoom in this order:
- Display profile for that display’s ID (if one was saved)
- Else a matching zoom rule for width × height × scale factor
- Else
smartZoom.defaultZoom
Known Limitations
- Integer zoom only — Smart Zoom uses whole zoom levels. Exact fractional per-window zoom is limited by public editor APIs.
- Wayland — automatic display detection is unsupported; Smart Zoom shows a one-time warning and keeps the current zoom.
- Does not use global
window.zoomLevel as per-window state — zoom is applied to the focused window so other windows stay unchanged.
- macOS permissions — if detection fails, grant Screen Recording access to your editor and reload the window.
