You can make it auto-start in this mode by going into Settings and checking the "Start with Windows" box. That way you'll never even see the main dialog box unless you want to!f
Another way is to pin this shortcut in your taskbar. You'll then be able to press Win+1, Win+2, etc.
I would recommend using AutoHotkey or some other global hotkey manager to run the command line, since it's able to grab keypresses even if another app has focus.
I am no longer around the setup in question, basically 3/4 of the screen is blanked, showing the bottom of the screen and the right side. Like a backwards L.
And yes, there is no artificial limit imposed by MultiscreenBlank itself. There is a practical limit imposed by Windows but I don't know what it is.
What I am looking to do is this: Blank the tv's and projector, and use the monitor as a preview source. So, if at all possible, I need the option to put my tv's and projector into one group separate from my monotorious and laptop lcd screen. If it can be done GREAT! Thanks in advance.
Now assuming it's a splitter/expander like a TripleHead2Go... Windows will treat each splitter as a single big screen. So you'd go into MultiscreenBlank settings and then the Virtual Screens tab. Select the physical display that corresponds to the combined splitter screen and click on it.
You can then split it in half horizontally/vertically (if both screens are the same size) or click "custom split" to split it into even more pieces (e.g. 3+ screens). If the different screens are different resolutions, you might need to directly edit the .ini file.
Once you have the virtual screens in place, you can group them just like physical screens and then use the regular grouping feature to manage them.
If you want to preview content on a blanked screen... you're sort of out of luck for now since MultiscreenBlank deals with Windows-based screens and not hardware screens. But I'm thinking of adding a feature where it can use accessibility APIs to take screenshots of blanked screens and allow you to sort of get an idea of what's going on under them.

So that if a display is currently dimmed to 65%, restore to normal... otherwise if normal, fully blanked, or dimmed to anything other than 65%, dim to 65%. Otherwise, brilliant program, thanks! I'm using EventGhost to capture the Pause/Break key to run MSB via command line to toggle one of my displayport monitors, since turning this monitor on/off using the power button causes it to disappear in Windows (this is a "feature" of displayport) and any windows/icons are moved to other monitors. MultiscreenBlank fixes the problem perfectly!multiscreenblank2 /toggle group 1 dim 65@Ringo Make sure you extract the program to a writable location, or alternatively use the provided .ini file and edit it to a different writable location.
My configuration is this:
NVIDIA GeForce 980 Ti
Primary Display: Samsung LU28E590DS/ZA (running off of DisplayPort)
Secondary Display: Philips 277E6 (running off of HDMI)
The 2.0.0.6 version will dim the primary display but not my secondary.
Thank you so much!
Thanks!
I use it to watch full screen video on external monitor #2 (dimming 1 and 3) and to dim all screens at night (since current Win10 Night Light only seems to dim/red-shift my primary screen on my Surface but not the other 2 external monitors).
Feature Votes and Ideas
- Dim from the command line
- Save dim settings with a group
- Double-click group toggles default (dim or blank)
- Dim on sun schedule (dim sunset, un-dim sunrise)
- Dim to a different color temperature (like Night Light)
- Assign a screen to more than one group
Bug
- I see a very thin, bright line at the far left of my external monitors when I dim or blank the external monitors.
Thanks for the good work.
I can't, however, stop the command prompt from taking focus from the game, which makes the use of the program very situational. Anyone have a better solution or no of a way I can make this work?
Run, batch.bat, , HideI plan to add (working!) support for toggling groups in a future update.

Hi there,
in a similar way, I would like to have this tool accessible via the "sidebar" from 8gadgets package. This would be really nice.
@Frederik S You'll need to figure out a way to add a custom shortcut/widget. You can then use command line arguments to actually have MultiscreenBlank do its thing.
Do you want it to stay open on top of all other windows?
Something similar to how Multiscreen Blank 1.1.0 labeled each monitor icon with 1, 2, etc but using more descriptive text.
The new feature could allow a user supplied text label field for each icon to be shown, or a checkbox option that would display the Physical Device ID (shown after the last slash in the "Information..." popup such as DISPLAY1, DISPLAY2, etc) within the icon.
Thanks, and thanks for the great utility!
Would be nice to have some guidance other than "here are the command lines, just throw them at the computer until it does what you want"
1. Open the Command Prompt and run from there (one off).
2. Create a batch file (text file with .bat extension) and list those commands in there. Double-click to run it.
3. Create a Windows shortcut with that command. Double-click the shortcut to run it.
4. Run as a script from another program that supports it, such as EventGhost
As for what to put in the command itself... unfortunately that depends heavily on what you're trying to accomplish here. That's why they're provided as examples. If you can describe your display configuration and what you want to do with MultiscreenBlank, I can likely point you in the right direction.
General format is
multiscreenblank2 /OPERATION SELECTOR PARAMETEROPERATION is what you're trying to do -- blank, reveal, etc
SELECTOR is the screen(s) you want to apply that operation to -- a specific screen based on pixel bounds, a group of screens, etc
PARAMETER is the details of selectors that require it -- actual pixel bounds, group number, etc. Some selectors (current, all) don't take parameters so nothing needs to be specified for those.
I am intentionally not adding automatic numbers to the monitor display due to Windows being rather arbitrary with them -- but user-specified text (with whatever numbering scheme you choose) should be doable.
Either that or you've left out a crucial detail. If that's the case, then I guess that's what I'm asking for.
My other comment must have gotten lost. It contained a link to a lightshot screenshot.
If it's as simple as opening the command prompt, typing any of the example commands, and pressing ENTER, then it simply doesn't work because that's exactly what I did. The following error is displayed, no matter which example command I try:
'MultiscreenBlank2' is not recognized as an internal or external command,
operable program or batch file.
The app is saved in a folder with the same name on my secondary HDD (F:\Programs\MultiscreenBlank2\MultiscreenBlank2.exe) and running in standalone mode.
F:cd \Programs\MultiscreenBlank2
or update your PATH variable as described here to include the install directory if you want it to work from any command prompt (no matter what working directory it's in).
These are steps you'd need to take with pretty much any command-line utility that you manually copy to a given location.
Wow. Way more too this than I thought, lol. Like I said, total newbie here.
If I understand you correctly, using the much MUCH easier of the two options, I would have to include the cd command in the batch file I want to write, yes?
I *think* from there I can figure out how to make a keyboard shortcut (ALT-CTRL-M or something like that) and run the batch file.
Thanks for your help.
If you're trying to use AutoHotkey or something to make keyboard shortcuts, you should be able to just call MultiscreenBlank directly (using its full path) with no need for an extra batch file.
Never used AutoHotkey, would prefer not to. I was under the impression that setting macros to shortcuts was pretty simple to do in Windows, though.
What I know:
- Both shortcuts work when double-clicked, even when both are hidden (set to still "show" in explorer obviously)
- Swapping the respective key combos - no change.
- Changing the reveal selector from ALL to specific display ID - no change.
- Changing the reveal command from /REVEAL to /DIM00 - no change.
- No errors are shown, reveal command/batch simply doesn't run except when double-clicked.
The reveal command outright refuses to work with key combos. I'm stumped.
I will not download and install AutoHotkey just to use it for this one, simple thing!
Changing the Dim command to toggle the specified display does not work with key combos either, but at least I can simply double-click the blank screen to reveal it again.
This is just bizarre, and I guess it's down to the app's programming.
Still won't use AutoHotkey. That's a rabbit hole I just don't have room for in my life.
is there any option to add feature like:
If I open full screen app (game or movie) the second (or more) screen will be blanked automatically? It could be a new checkbox in settings tab.
It would be awesome, really ;)
Cheers
AutoHotkey is really simple. Just install it and create a new text file. Name it something like "blank.ahk" (the ".ahk" extension is needed). Then put this in:
^!b:: Run, C:\Path\MultiscreenBlank2.exe /dim75 all return ^!r:: Run, C:\Path\MultiscreenBlank2.exe /reveal all return^!b:: means "when Ctrl+Alt+B is entered, do the following" and the command below it will dim all screens to 75%. So if you press Ctrl+Alt+B, the above script will dim all screens. If you press Ctrl+Alt+R, all screens will be revealed.
As an example, this is the batch file I use for launching GTA V. I have MultiscreenBlank2 in my PATH and put the batch file in the same folder GTA V is installed in.
This blanks all screens except the one GTA V is running on, launches GTA V, waits until it closes, and then reveals all screens.MultiscreenBlank2 /blank allexcept ID \\.\DISPLAY1 start /wait GTAVLauncher.exe MultiscreenBlank2 /reveal allthx for providing this great tool! I think it could be the first step to solve my problem, but I'd need some more help to get the second step done too.
I run a sim rig with one large nvidia surround triple screen and another 4th info monitor. I would like to be able to blank the 4th info monitor by a joystick button (while in the simulator) to show or hide the info on the 4th monitor.
With this tool I can select and blank this monitor. But I'd need to bind a hot-key to blank/show this given monitor and a way to call this hotkey via a joystick button (usb button boxes). So far I don't know how to do either of that.
Maybe some of you can help me with that?
Once you figure out how to detect the button with those programs it's easy, just make AHK/EventGhost run the correct command line to toggle that screen.
Thx so much for your quick reply. I was looking into Autohotkey - I'd prefer to avoid using another tool - but I am currently struggling to configure the same hotkey to start your tool to blank a given monitor and then reveal it at the second press. The script does not allow the same hotkey for two actions. At least not in that simple way I tried to copy from another reply from you above. I could use this as a temporary workaround to be used with hotkeys of my corsair keyboard until I get the joystick solution working - but it only makes sense if it works with the same hotkey to blank and reveal the monitor.
The buttonboxes are shown as HID-compliant gamecontroller. But I have no clue of how to address them directly. Window diver preferences give some hardware IDs, but I have still no clue of how to select and bind a given button to a hotkey - script. : (
Works like a charm! Thank you sooo much for this tool and your fantastic idea to use EventGhost. This seems like an amzing tool by itself..
Successfully bound a buttonbox button to blank and reveal the 4th info monitor! That's absolutely fantastic to be used while in the sim to show those additional infos when necessary and hide them otherwise!
All the best in 2019 and thx for your super quick help!

Unfortunately a password-protect feature would be completely worthless since you can easily kill it with Task Manager and can even access the Start menu by pressing the Windows key.
Windows lock should not be rearranging things -- is it possible that your monitors are sleeping soon after the lock, which is what's actually causing the rearrangement? In that case you should be able to disable "Turn off the screen" in Windows power settings.
Is there a way to have it opened as regular window instead of minimized?
1. Don't start with Windows. This way it will open to the last on-screen position when you launch it without command line arguments.
2. Quit and re-open.
multiscreenblank2 /quitmultiscreenblank
I've found this program based on an idea I had, that a monitor should be dimmed when you don't look at it. My ideal would be to have it use eye tracking AI and a webcam feed, but it might be simpler to base it on a cursor location.
Thanks for your consideration!
Thank you for doing such a nice job. I am testing the software at this moment and it seems to do exactly what I want it to do!
You thing that makes it 100% perfect for me is to have command line parameter for the fade duration. This is because sometimes I want to fade out/in more quickly than other times in a batch file.
Do you think that is possible?
I also noticed that you can’t use /minimized and an other parameter at the same time. Is that correct?
Regards,
Fred
You CAN run /minimized together with other parameters, but /minimized has to be the first one. So you can do:
multiscreenblank2 /minimized /blank current...but you cannot do this:
multiscreenblank2 /blank current /minimizedI am a volunteer to be a technician to do a "school play" (more like a summer school) and I have to show some videos (as backdrop) on a beamer.
The problem is that the children performing the play are really young (5-10yrs). So it is impossible to create a video with fixed length.
I start the video and wait until they say a line that would be my cue to fade the video. However I have to show multiple videos with different fade times. There lies the problem.
As work-around I created multiple ini files with the fade times and a script to replace the ini file that should be active. On one occasion I have to set a different fade time while the screen is dim at 50%. Using /quit will set the brightness back to 100%, so that trick cannot be used in that case. But your program is now already 95% perfect, And although I would kindly request this feature, I don't want to push you in any way!
Many thanks for you quick reply and have a nice weekend! Regards, Fred.
At the very least you could run both programs simultaneously to hold a 50% fade on one monitor while independently doing a full fade on top of it.
One issue: I work on a laptop which I connect to a docking station into which 2 screens (tvs via hdmi) are plugged in. It works fine. But at the end of the day I close the laptop and put it to sleep. When I open it and hit "blank all but main" it blanks the main instead. Not only that, I can't seem to blank the non-main screen at all until I restart.
Is there something I'm missing? Thanks!
I suspect that many people (me included) use the "Blank all but main" command more than any other. Right now I right click on the taskbar icon and click "Blank all but main" many times during the day. It would be great to configure the taskbar icon so that a left click did your most common operation - in my case, blank all but main.
Just a suggestion - many thanks for a great program.
I will look into adding a "single click action" setting when I get a chance. For now you can create a Quick Launch shortcut or bind a key on your keyboard (via AutoHotkey or EventGhost) and run the following command to accomplish the action you want:
Or if you want to blank all screens except the one the current mouse is on:MultiscreenBlank2 /blank allexcept id \\.\DISPLAY1
Personally I use the keyboard macro for this, usingMultiscreenBlank2 /blank allexcept current/toggleso pressing the key a second time reverts it.1. I'd love if there could be a running program watchlist of sorts, where you specify the programs to watch for, and when they're detected, blank/dim the specified monitors/groups. For example, I have a 3-monitor setup, and when I run Netflix or Plex (on the center monitor), I want my side monitors to dim or blank.
2. For my use cases, I actually prefer dimming instead of blanking entirely. Is there a way to set "Dim x%" as default for various operations (eg. double-clicking a monitor representation) instead of "Blank"?
Thanks for an awesomely-useful app!!
Default operations and "toggle dim" is a good idea, I'll see what I can do next time I get a chance to work on it..
Just to be clear, I didn't mean applying dimming to individual programs. I meant dimming entire (selected) screens when a specific program was detected running. Not sure if that's what you understood or not, just clarifying. :)
@nookkin Added shortcuts including left and middle click on the tray icon. Downside of left-click is Windows doesn't provide a good way to distinguish between two single clicks vs. a double click for tray icons.
@Michael C. unfortunately didn't get a chance to implement default dimming action yet as that would require a bigger rewrite, but it'll happen eventually!
Currently I achieved the result I want with additional third-party software which listens to my key combinations and executes multiscreen blank executable with certain parameters and while I was downloading that software and setting it all up I kept wondering why this is not a feature in your software :)
This is also achievable with Windows shortcuts (you can specify key shortcuts there), but it's quite unreliable and sometimes randomly you have a few seconds delay before it is executed. From what I understood this is because Windows waits for other apps to respond to that hotkey and not all apps are responsive in this matter so there is timeout of 3-4 seconds or so. This method doesn't require any additional software but I found it unreliable and decided to go with WinHotKey.
Of course this is also doable with AHK and AutoIt too.
This functionality seems quite logical for this type of software so I hope you'll consider adding it :)
Toggle Dim is planned for the next release! Can't give you an ETA unfortunately. Hopefully before the end of 2019.
multiscreenblank2 /toggledim50 current@Tony Cross Unfortunately not possible today, as that would probably require putting the monitor to sleep via DPMS (and that tends to make Windows not see the monitor any more, rearranging all the windows). You'll have a better chance using the button on the monitor as some of them keep the signal alive.
Ok, that's fair enough, I've experimented with other software that turns one monitor off and seen how that messes up where all the windows end up.
However, the monitor backlight is affected by the brightness control isn't it? It certainly seems to be so on my Asus ProArt monitor. Would it be possible to set the monitor brightness to 0 to reduce the backlight when blanking the screen? Perhaps add a setting value to specify the screen brightness to be restored when un-blanking?
@Tony Cross Dimming physical monitor brightness is theoretically possible via DDC/CI but not necessarily possible to dim all the way. There's also a lot of buggy implementations out there.
I am changing the brightness now using a tool from Nirsoft but it means two separate actions; dim the brightness then blank the screen, followed by revert the screen and replace the brightness. It would be so much better if your tool could do both. :)

I have two batch files working now that use your tool to blank/reveal the screen and a NirSoft tool to dim/brighten the monitor settings. The reveal batch file shortcut is assigned a keyboard hotkey which works - except when the (primary) screen is blanked via your tool.
I have a shortcut on the taskbar so can reveal my primary monitor via the second screen, but do you know why the shortcut hotkey doesn't work when the primary screen is blanked?
What would be really good is if I could map the 'double-click on a blanked screen' to a specific batch file, then I could run my reveal batch file just by double-clicking the screen. I already have the 'blank the screen' batch file mapped to a right-click on the screen.
I switch between two screen setups using Helios Display Manager. This allows to switch between single screen setup and nvidia surround screen setup.
Normally I use MultiScreen Blank to turn off the 4th info screen sitting above a triple screen monitor setup as one large nvidia surround screen. Sadly I have to switch to a 4 single screen setup for a few games. In order to be able to use MultiScreen Blank after having swtiched the screen setups (MSB then still shows the old/wrong screen setup) I have to open settings and close them again, which reloads the correct screen setup.
So in this situation it would be great to have a F5 / refresh function to load the current (changed) screen settings into MSB.
cheers,
Bernhard
PS Super thankfull for the existence of this tool as I used it many times daily!!
Is it also posible to add a image? Maybe also combinate it with the brightness function?
@Bernhard I'll keep this in mind for a future version, will probably want this configurable in some way as reloading will likely end up revealing screens unexpectedly if the dimensions don't match exactly
But sometimes it won’t blank and the taskmsnager says it couldn’t run.
Is there some how a force run?
Guy
I'm still seeing notifications and stuff on them.
I implemented a timer a while back (where it would repeatedly bring the window to the top) but that made it almost impossible to close and introduced lag. I'll revisit that when I get a chance!
I tried every monitor app I could find for a simple solution to dimming or blanking monitors with the mouse. Either they did not have the feature or I could not figure out how to set it up. Most had way more features than I was looking for anyway. The screen savers, split screens and customizable task bars were nice but I wasn't really looking for all those bells and whistles.
Finally I decided to dig deeper into the Multiscreen Blank help files because they seemed to be saying that I could create some kind of clickable shortcut. I'm not big on Hotkeys; its too much trouble trying to fumble around and find the right keys to press. I prefer to just click my way around the internet.
After some trial and error, I finally managed to create a working desktop icon that would blank my second monitor. I never could figure out how to make a proper shortcut so I finally just right clicked on another exe file and selected create shortcut. From there I renamed the new shortcut, changed it's icon and modified its properties to reflect those in the Multiscreen help files. With one working shortcut, making two more was easy.
I decided to go one step further and make some customized icons that have a blue background to match my taskbar with the text D1, D2 and T2 (toggledim1, toggledim2, toggle 2). All three shortcuts were then placed in the quick-launch.
I use this every day, working, watching movies, working while watching movies etc. Glad I decided to take a closer look at Multiscreen Blank. It ended up being exactly what I was looking for.
Its pretty much perfect like it is but here's some suggestions anyway :).
Make a YouTube help video. No videos anywhere for people like me who don't know how to make shortcuts or set up any of the options.
Don't know if its even possible but another cool feature would be some kind of slider in the main window. Instead of needing to change the shortcut you could just do toggledim_slider and dim to whatever level you have preset.
Larger font for the monitor names, they are really small on my display.
That's it. Thanks for making a great app.
For shortcuts, you can use MultiscreenBlank.exe and right-click-drag to create it, then modify the parameters.
There's no slider in the main window but you can right-click an icon and select a specific Dim level from a few presets (custom levels will happen eventually).
You can also create shortcuts for the tray menu (which you access by right-clicking on the MultiscreenBlank icon instead of wasting taskbar space). Do this from the "Shortcuts" tab in Settings.
I'll consider more UI customizations like font size too. Unfortunately can't promise an ETA as I'm unusually busy these days.
1 question: I current have:
"D:\MultiscreenBlank2\MultiscreenBlank2.exe /blank id \\.\DISPLAY3 id \\.\DISPLAY4"
to blank 2 screens but is it possible to also add a dim arg to also dim \\.\DISPLAY2?
example: "D:\MultiscreenBlank2\MultiscreenBlank2.exe /blank id \\.\DISPLAY3 id \\.\DISPLAY4 /toggledim70 id \\.\DISPLAY2"
Just solved it by launching the program twice with two different shortcuts with different arguments.
Am I right that blank screen will prevent burn ins?
Moreover, is there any workaround to make timed blanking of screen which is not used (mouse cursor is not used on it)? And revealing when cursor moves in?
P.s. make "donate" page :)
While there is not a Multiscreen Blank donation link at present, there is a donate link for the NPS Image Editor program at:
http://nps.nookkin.com/donate.ndoc
Even though the link is specified for another program, any money donated there will still end up supporting Alexey "Lyosha" Blinnikov.
Done and done. Thanks Darrell !
Thanks for the app Nookkin!
I went through the whole thread and saw a couple of guys asking the question I'm about to ask but it seems it remains unanswered... or I just didn't see the answer for what it was, so here I quote Sergio:

First off, love the software, and thank you for giving it out for free!
Second, I've got an issue that I hope you can help with. Right now I'm using the software to create a mirror of a display, and display it on a second display, which works perfect. The issue that I'm running into, is that I don't have a way to CLOSE the mirrored window, without running a batch script as an admin, which I can't do for the use-case I have. Is there any way to close a mirrored window with a command line shortcut?
As a sort of nuclear option workaround you can run the below to close everything which will close all mirrors as well
multiscreenblank2 /quitAnd of course you can manually close a full-screen mirror by right-clicking on it
I would like to know if this software is able to fully blank a 34 inch ultrawide screen?
The limitation is it can only display a black image, it won't actually put the monitor to sleep via DPMS.
