The Dynamic Resolution Manager, or DRM for short, is simple Windows program that resides in your tray. When right-clicked, it opens a menu, where you can choose a new resolution:
(Don’t worry about the font in the screenshot – it follows your system font. It’s just that I personally happen to use Verdana as my system font.)
The “dynamic” part – and the main selling point – is that the program retains the window layout across resolutions. For example, let’s say you have two windows side by side, together covering the entirety of the screen. When you switch to a lower resolution using drm, the windows will automatically be repositioned and resized to cover the exact same area; the full-screen side-by-side layout will be retained regardless of resolution. In other words, drm retains the centimeter-measured positions and sizes of all windows, rather than the pixel-measured.
The resizing and repositioning is
instantaneous and invisible, and it applies to all windows, even
those that are currently minimized. Below is an example, where the
window layout is retained when switching from 800×600 to 640×480.
drm is configured via a set of registry keys located in
HKCU\Software\JohnAJ\DRM. They will be created
automatically when the program is launched for the first time.
||Set of custom resolutions. Since 1.4, refresh
rates can optionally be specified.*
||Set of programs whose window position and
size should be ignored (1.2).**
||Set of programs whose window size should be
ignored, but window position retained (1.2).
* Resolutions are specified using the following notation:
width "x" height [" " refresh rate "Hz"], with the
section enclosed in brackets being optional. Each resolution is
then separated by a pipe (|) character. Since 1.4.1,
two pipe characters in a row (||) are rendered as a
separator in the menu.
** These windows will still be repositioned and resized, but always to their original pixel-measured position and size. (As such, it will still behave differently from Windows’ normal operation, which is to shrink windows that don’t fit on screen.)
To quickly open the configuration in Registry Editor, click the Configure…
menu option. Note that you must restart drm in order for any
configuration changes to be applied. To easily restart drm, hold Shift while opening the menu, which replaces the Exit option with a Restart option.
If you want to customize the handling of specific windows
further, use the non-compiled version of drm, drm.ahk (browse versions), which you can easily modify
yourself. Note that this requires AutoHotKey to be
installed on your system.
Since version 1.3.2, drm.ahk includes a designated place
(around line 196, as of 1.4.2) where you can write your own custom rules. The
included example, shown below, would instruct drm to ignore the
size, but retain the position, of any window of the mpc-hc.exe
process with a client width of 294 pixels:
; Custom rules
; if (exe = "mpc-hc.exe" and cw = 294)
; DoIgnoreSize := true
Code in this section of the program is run once for every window, whenever drm initiates a resolution change. You can easily control how drm should handle a specific window by setting one of the variables DoIgnore and DoIgnoreSize to true. This is equivalent to adding the program to the Ignore or IgnoreSize registry key.
This approach, while more powerful than the registry-based
configuration, requires some knowledge of AutoHotKey, some
understanding of drm’s source code (which, however, is relatively
simple) and, finally, a slightly more manual update process,
should a new version of drm be released.

source code yourself. If you add a feature or fix a bug yourself,
