Black Screen

The Black Screen application provides control over monitor display to manage work and rest time. The software executes total or partial screen dimming through configurable keyboard shortcuts. This mechanism serves to interrupt continuous activity in front of the computer, encouraging regular breaks. The main function involves temporary screen blackening, which acts as a physical reminder to look away from the monitor. The implementation includes customizable timers for work and rest intervals, following principles of structured productivity methods. The application operates in the background with minimal system resource consumption.

• Instantaneous keyboard dimming. Activation via key combination produces the immediate switch to a completely black screen. This state is maintained until the same key action is repeated, restoring the desktop and applications to their previous state. The process avoids the need to physically turn off the monitor, keeping all system processes running. The function addresses the need for quick visual interruptions during prolonged work sessions.
• Programmable timer for breaks. The configuration allows setting regular intervals after which the screen automatically darkens. Work and rest periods are independently adjustable, with ranges from minutes to hours. The system visually notifies the transition between states through gradual or instantaneous lighting changes. This automation establishes discipline in the distribution of time in front of the screen.
• Pomodoro technique implementation. The application integrates the methodology of focused work intervals followed by short breaks. The standard cycles of 25 minutes of activity and 5 minutes of break are customizable according to individual requirements. After four completed cycles, a longer rest interval is automatically activated. This structuring of work time increases concentration during productive phases.
• Attention reset with visual content. During the black screen period, a key press displays randomly selected images from a configured collection. The photographs remain visible for a set time before returning to the dark state. This function provides a visual stimulus that momentarily distracts attention from cognitive work. The sequence can be repeated several times during the break, offering variety in the displayed content.
• Selective multi-monitor control. On systems with multiple connected screens, dimming can be applied to specific displays. Assigning different keyboard shortcuts allows managing each monitor independently. This function is particularly relevant in setups where different screens show differentiated information. Granular control maintains visibility on designated monitors while others remain darkened.
• Multiple configuration profiles. The application stores separate setting sets for different usage contexts or users. Each profile contains its own time intervals, keyboard shortcuts, and notification behaviors. Switching between profiles is done through a menu accessible from the notification area. This organization facilitates adaptation to different tasks or daily routines without manually reconfiguring parameters.
• Customizable transition modes. The visual effects during the switch to a black screen can be adjusted among several available options. Variants include gradual fade, curtain, blind, or instantaneous change with no intermediate effects. The transition speed is also configurable, from immediate changes to slow transformations lasting several seconds. These settings determine the perceptual experience during transitions between work and rest states.
• Activity log and statistics. The system maintains a detailed history of completed work sessions, with timestamps for each transition. Collected data includes duration of productive intervals, frequency of breaks, and consistency in completed cycles. Information is presented through graphs and numerical summaries over daily, weekly, or monthly periods. This retrospective analysis allows evaluating work patterns and adjusting settings to optimize productivity.
• Integration with calendar systems. The application automatically detects events in linked calendars to adjust its scheduled behavior. During virtual meetings or important presentations, automatic notifications and dimming are temporarily suspended. This synchronization prevents inopportune interruptions during periods requiring continuous screen attention. Compatibility includes enterprise calendar platforms and personal productivity applications.
• Non-intrusive pre-break notifications. Before activating automatic dimming, the system displays discreet alerts allowing the user to postpone the break. These reminders appear in the screen corner with options to delay the interruption for set minutes. Notification design minimizes workflow disruption while effectively communicating the proximity of a scheduled break. Customization includes types of visual, audible, or combined alerts according to user preferences.
• Conditional sleep mode. Detection of specific activity in certain applications can temporarily inhibit automatic breaks. This mode is useful during tasks that cannot tolerate interruptions, such as batch processing, rendering, or prolonged data transfers. Suspension criteria include high CPU usage, specific foreground windows, or designated critical processes. Once the exceptional condition ends, the system resumes its normal scheduled operation.
• Voice command compatibility. Integration with voice recognition systems allows controlling main functions through spoken commands. Supported commands include manual activation of the black screen, pausing the timer, or querying the time remaining in the current interval. This control modality is particularly useful during tasks that keep hands occupied with specialized peripherals. Configuration requires a functional microphone and accepts the main operating system voice recognition engines.

Black Screen development began in 2019 as a personal project to address eye strain during long programming sessions. The initial creator identified the need for regular interruptions that did not rely on mental reminders or applications with intrusive notifications. The first functional version implemented only manual dimming using a simple key combination. Subsequent evolution incorporated automatic timing functions after receiving feedback from initial users.
