+# Multiple Resolutions and Aspect Ratios with C#
+
+**Note:** This demo is intended to showcase what Godot can do in terms of
+supporting multiple resolutions and aspect ratios. As such, this demo very
+full-featured but it's also fairly complex to understand.
+
+If you're in a hurry and want to implement *decent* support for multiple
+resolutions and aspect ratios in your game, see [Multiple resolutions crash
+course](#multiple-resolutions-crash-course).
+
+**Note:** There is a GDScript version available [here](https://github.com/godotengine/godot-demo-projects/tree/master/gui/multiple_resolutions)
+___
+
+This project demonstrates how to set up a project to handle screens of multiple
+resolutions and aspect ratios.
+
+This demo allows you to adjust the window's base resolution, stretch mode,
+stretch aspect, and scale factor (internally known as "stretch shrink"). This
+lets you see what happens when adjusting those properties. Make sure to resize
+the project window in any direction to see the difference with the various
+stretch mode and stretch aspect settings.
+
+The GUI can be made to fit the window or constrained to a specific aspect ratio
+from a list of common aspect ratios. On ultrawide aspect ratios, this can be
+used to prevent HUD elements from being too spread apart, which can harm the
+gameplay experience. For non-essential HUD elements, specific controls can be
+made to ignore this aspect ratio constraint when it makes sense (e.g. a list of
+players on the side of the screen).
+
+Additionally, a GUI margin setting is provided to better handle TVs with an
+overscan area to prevent GUI elements from being cut off. This can also improve
+the gameplay experience on large monitors by bringing HUD elements closer to the
+center of the screen.
+
+A DynamicFont with multichannel signed distance field (MSDF) rendering is also used.
+This allows for crisp font rendering at any resolution, without having to re-rasterize
+the font when the font size changes. This makes changing the various settings in this
+demo faster, especially when large font sizes are used as a result of the GUI scale factor
+setting being increased.
+
+Note that by default, Godot uses font oversampling for traditional rasterized
+DynamicFonts. This means MSDF fonts are *not* required to have crisp fonts at
+higher-than-default screen resolutions.
+
+Language: GDScript
+
+Renderer: Compatibility
+
+## Technical notes
+
+The demo works with the following project settings:
+
+- `canvas_items` stretch mode (this was called `2d` in Godot 3.x).
+  Recommended for most non-pixel art games.
+- `expand` stretch aspect (allows support for multiple aspect ratios without
+  distortion or black bars).
+- Using a base window size with a 1:1 aspect ratio (`648×648` in this demo).
+  This prevents GUI elements from automatically shrinking, even in portrait
+  mode.
+  - With this setting, to prevent the GUI from breaking at narrow aspect ratios,
+    the GUI must be designed to work with a 1:1 aspect ratio. This is not
+    feasible in most complex games, so a base window size with a wider aspect
+    ratio (such as 4:3 or 16:10) can be used instead. The wider the aspect
+    ratio, the easier design becomes, but the GUI will automatically become
+    smaller at narrow aspect ratios unless the user overrides its scale with the
+    stretch shrink setting. Many devices such as the Steam Deck and MacBooks
+    feature 16:10 displays, so it's recommended to use a 16:10 resolution or
+    narrower as a base window size to ensure a good gameplay experience out of
+    the box on those devices.
+- Using a window size override with a 16:9 aspect ratio (`1152×648` in this demo).
+  This way, the project starts in a 16:9 window even if the base window size has
+  a 1:1 aspect ratio.
+  - The test window height matches the width and height of the base window size,
+    so GUI elements are still at the same size.
+
+## Multiple resolutions crash course
+
+**Not everything in this demo is critical to all games.** For gamejam projects or mobile games, most of this can be skipped.
+See the [Common use case scenarios](https://docs.godotengine.org/en/stable/tutorials/rendering/multiple_resolutions.html#common-use-case-scenarios)
+section in the Multiple resolutions documentation.
+
+With the simpler setup described in the above documentation, there are a few
+limitations compared to this demo:
+
+- The HUD will shrink when the aspect ratio becomes narrower than the base
+  window size. As such, it's recommended to use a base window size with a 16:10
+  aspect ratio to prevent the HUD from shrinking on Steam Deck and MacBooks.
+- Players will not be able to define a margin, which can be problematic when
+  playing on a TV (as overscan can obstruct some HUD elements). This can be
+  worked around by ensuring the entire HUD always has a small margin around it.
+  This can be done by increasing the Margin properties on all sides on the root
+  Control node by 10-30 pixels or so.
+
+If you're releasing a full-fledged game on a desktop platform such as Steam,
+consider implementing full support as this demo suggests. Your players will
+thank you :slightly_smiling_face:
