If you buy a tablet or monitor for the clock, choose a screen that shows black well in the dark, from best to worst:
OLED ► VA ► IPS, PLS ► TN
|
 |
If the black background still glows, lower the screen brightness, even to 0%: “Quick Settings” ( Win + A ) on Windows 11, “Quick Actions” in the Action Center ( Win + A ) on Windows 10.

NOTE: Some devices stop working when their battery dies, and some batteries can't be replaced. Choose a device that keeps working on power with a dead battery, from a manufacturer you trust. For a portable monitor, HDMI, speakers and a touchscreen are useful.

Installation
1. Download and open the JocysCom-ClockForComputer.ZIP file.
2. Copy its Jocys.com folder to where you keep programs, for example “C:\Program Files\”:
3. Run JocysCom-Clock-Program.EXE to use the clock as a program, or install JocysCom-Clock-ScreenSaver.SCR as a screen saver.
Keep the “Themes” folder next to these files: the themes find their pictures there. Videos, sounds and web pages play in Microsoft Edge WebView2, which Windows 11 has. If it is missing, the clock offers to install it.
Clock SCREENSAVER (*.SCR)
Right-click JocysCom-Clock-ScreenSaver.SCR (on Windows 11, then “Show more options”) and choose Install, Configure or Test. Configure opens the clock with the screen saver's own settings, where you change how the screen saver looks.
Windows Screen Saver Settings
On Windows 11: Start ► Settings ► Personalisation ► Lock screen ► Screen saver
On Windows 10: Start ► Settings ► Personalisation ► Lock screen ► Screen saver settings
On Windows 7, 8.1: Right-click on Desktop ► Personalize ► Screen Saver
To remove the clock from the list: rename, move or delete the JocysCom-Clock-ScreenSaver.SCR file, then open “Screen Saver Settings” again.
Clock PROGRAM (*.EXE)
The line at the top of the settings panel says what a control does: point at it, right-click it, hold a finger on it, or move to it with the Tab key.
To save theme files in protected folders, such as “C:\Program Files\Jocys.com\Clock for Computer\Themes\”, run the clock as administrator.
Alarm Sound, Video or Web Page
In the ALARM settings tab, type or paste a web link into the box, or click the folder button beside it to choose a sound or video file (mp3, wav, ogg, flac, mp4, mkv, webm…). The ▶ button plays the alarm now. Snooze ( + ) sets alarm 3, so the alarm 3 settings choose what plays after a snooze; a snooze rings once.
A video or web page covers the clock, or its preview while the settings panel is open, and fills the screen when the clock is full screen. HIDE BROWSER plays it hidden, so you only hear it. The loop button repeats a file; a web page repeats only if its own link says so, as with “loop=1”.
Built-in sound 1 ( ♪ ) rings instead if there is no Internet connection, the file is missing or can't play, Microsoft Edge WebView2 is missing, or a web link plays no sound in 20 seconds. If a web page asks about cookies, play its link as an alarm with STOP MEDIA ON MOUSE MOVE off, and answer it: the clock remembers the answer.
STOP / CLOSE Media
Buttons show over a playing alarm. STOP MEDIA ON MOUSE MOVE, set for each alarm in the ALARM settings tab, decides how the alarm stops. While it plays, its button over the media, or the Ctrl key, turns it ON or OFF.
 |
“Stop Media on Mouse Move” ON
To STOP / CLOSE media:
Move mouse pointer
Press keyboard key
Touch screen
|
“Stop Media on Mouse Move” OFF
You can click on web page links.
To STOP / CLOSE media:
Press “Stop” (X) button
|
 |
Use “youtube.com/embed” links, as in these examples: they show only the video, without the rest of the YouTube page, and the clock makes the playing video fill the clock.
Link options are separated with the &
autoplay=1 - play the video at once.
loop=1&playlist=JFaNzIElWvs - repeat the video.
fs=0 - hide YouTube's full screen button.
To make a short alarm video from a longer one, you can use DaVinci Resolve, a free video editor.
Background Picture, Video or Web Page
OTHER settings tab ► BACKGROUND: click the folder button to choose a picture (jpg, png, bmp), or a sound or video file, or type a web link into the box. A video or sound repeats. A web page shows as it is, and its playing video fills the clock. Select OPACITY or VOLUME, then set it with the slider. The background pauses while an alarm plays and while the clock can't be seen.
Show on Top and Lock Clock
Clock icon menu in the taskbar notification area (on Windows 11 it can be under the “^” arrow):
Show on Top - the clock stays above other windows, such as media players. Also in the OTHER settings tab.
Locked - the clock can't be dragged or resized. Under the mouse it fades, and clicks go through it to the windows below. Unlock it in the same menu.
With Show on Top, also turn on “Always on top” in Task Manager ( Ctrl + Shift + Esc ► Settings or Options ), so that Task Manager shows above the clock.
Start Clock with Windows
OTHER settings tab ► START WITH WINDOWS (ON): the clock starts when you sign in to Windows. Each renamed copy of the program has its own. You can also turn it off in Task Manager ► Startup apps.
SCREENSAVER and PROGRAM
Disable Computer Sleep and Screen Turn Off
To keep the clock always visible, set the screen and sleep times to “Never”:
On Windows 11: Start ► Settings ► System ► Power & battery ( Power, if the computer has no battery ) ► Screen, sleep, & hibernate timeouts ( Screen and sleep, on older versions ).
On Windows 10: Start ► Settings ► System ► Power & sleep.
While a video background plays, the screen stays on and the computer doesn't sleep on its own.
Largest Digits Possible on Screen
24 hour format: HOUR3 COLON MINUTE in LAYOUT settings | JocysCom_*_Simple fonts in FONTS settings.
12 hour format: HOUR6 COLON MINUTE in LAYOUT settings | JocysCom_*_Simple fonts in FONTS settings.
With _Simple fonts, HOUR3 and HOUR6 show the hour “1” as a narrow “|”, so the digits can be larger.
Save, Load and Reset Settings
OTHER settings tab ► SAVE SETTINGS... / LOAD SETTINGS... / RESET SETTINGS... - choose which settings to save, load or reset:
CUSTOM: the settings you check
THEME: how the clock looks
USER: alarms, time zone, volume and where the clock is on the screen
ALL: every setting
Keep the pictures and media files of a theme in the folder of its saved file: then you can copy that folder to another computer, and the theme still finds them.
Settings DIRECTORY and FILES
Each Windows user has their own clock settings, in %AppData%\Jocys.com\Clock for Computer\ ( C:\Users\<UserName>\AppData\Roaming\Jocys.com\Clock for Computer\ ):
JocysCom-Clock-Program.Settings.xml (<ProgramName>.Settings.xml)
JocysCom-Clock-ScreenSaver.Settings.xml (for every screen saver file)
Logs (error details, which you can send with a problem report)
Web page data, such as cookies and the answers you gave, is in %LocalAppData%\Jocys.com\Clock for Computer\, one folder per program: JocysCom-Clock-Program.exe.WebView2, JocysCom-Clock-ScreenSaver.scr.WebView2.
To open a folder, type its name, for example %AppData%\Jocys.com\Clock for Computer, in the File Explorer ( Win + E ) address bar. To reset the clock, use RESET SETTINGS... Clock versions up to 2025 kept settings in C:\ProgramData\Jocys.com\Clock for Computer\; a user who has no settings yet starts from them.
To run several clocks, for more sizes and colors, copy JocysCom-Clock-Program.EXE and rename the copies, for example “Clock-Date.exe” and “Clock-Time.exe”. Each copy keeps its own settings: “Clock-Date.Settings.xml” and “Clock-Time.Settings.xml”. While RUN SINGLE CLOCK INSTANCE is ON (OTHER settings tab), starting a program that already runs shows its clock instead of a second one.
