Control Screen Brightness And Turn Off Monitor With iBrightness

Picture clarity in modern displays depend on the difference between brightness and contrast ratio. The farther these two are to each other, the better your image or video would look. Surely, keeping your LCD brightness high during gaming sessions or while watching a movie does make sense, as the picture becomes more vivid and bright. But when you’re using your PC at night with the lights turned off, doesn’t the screen seem a bit too bright? It puts strain on your eyes, and in the worst case scenario, can also harm your eyesight. Furthermore, when you’re surfing the web or doing some writing stuff on MS Word or writing an important email to your boss, you don’t want to keep the brightness level to the full. Whether you know it or not, more brightness also squeezes out more electricity, thus hefty bills to be paid at the end of the month. Although, you can change brightness level from within your LCD’s OSD, with iBrightness, a brightness control tool for Windows, you’d keep monitor power and display brightness controls at your fingertips. Whilst you can change the screen brightness from native display options available in Control Panel, iBrightness provides you a unified interface to change brightness. What’s more, it also enables to turn off monitor and activate desktop screensaver. More details after the break.

There is not much to talk about the interface, as the application has pretty fair amount of scarcity here. After installation, the application quietly runs in system tray, not disturbing your in whatever you’d doing. Right-click provides access to to its context menu which contains iBrightness (to change brightness), Turn Off Monitor, Screen Saver, Change Screen Saver and Auto Start options.


To change screen brightness, all you need to do is click its system stray icon to access the iBrightness console. Move the slider left and right to decrease or increase the brightness, respectively. It’s worth mention here that the incremental difference it provides is quite noticeable. You can keep the brightness between 0 to 100 percent. This miniscule console also gives you direct access to Screen Saver.

As mentioned earlier, other than enabling you to change screen brightness, iBrightness also provides options to turn off monitor, activate screensaver and change the screensaver. Select Auto Start if you want the application to run on Windows start up. iBrightness works on Windows Vista and Windows 7. Testing was carried out on Windows 7.

Download iBrightness


  1. Just downloaded it to my Windows 7 HP desktop. It seems to work fine and I love that it’s easily accessible, but the slider doesn’t progress smoothly. The lowest and highest settings are correct, but the inbetween jumps around, which is kind of painful. The only settings that seem to follow a linear progression are 0, 30, 80, and 100. Still, it’s free, and hasn’t tried to install malware as far as I can tell, so I’m happy. I usually just want highest and lowest settings anyway.

  2. Here are my observations, thoughts/suggestions…

    On the author’s web page, he says that it’s not been tested on Vista.  Well, it has now… by me.  Works fine.  I’m emailing the author to tell him.

    I already emailed him, though, because when I first launched it, my Hosts Intrusion Protection Service (HIPS) client popped-up a warning that the software is trying to access the “DNS/RPC Client Service.”  To see if it would work without it, I first answered not to allow it (and didn’t let HIPS remember my answer).  iBrightnessTray will definitely not properly launch and run unless it’s allowed to access the “DNS/RPC Client Service.”  So I re-launced it and, this time, told it to allow “DNS/RPC Client Service” access, and it works just fine.  Works on both 32-bit and 64-bit Vista… though, again, only if access to “DNS/RPC Client Service” is allowed.

    HIPS also pops-up a warning when one tries to change the screensaver in iBrightnessTray, indicating that it’s trying to access “control.exe” but at least that makes sense since “control.exe” is the part of Windows where the screensaver is specified.  Of COURSE iBrightnessTray would need to access that, so I’m okay with that one.  (Although, if on just thinks about it for a moment, other software which controls the screensaver — screensaver managers and whatnot — never need to access “control.exe” or cause the HIPS to alarm because of it.  Therefore, I worry, as I also express in the next paragraph, that this program author is inexperienced and doesn’t realize that there are ways to access the screensavers, and select one, without necessarily accessing “control.exe”

    But I’m REALLY confused about why a screen dimmer needs to access the “DNS/RPC Client Service.”  It certainly doesn’t need to do that just to “phone home” to check for updates.  Other software can “phone home” to check for updates without accessing the “DNS/RPC Client Service.”  I’m hoping against hope that the software’s author is, in fact, just phoning home to check for updates; but if that’s the reason, then he’s going about it the wrong way.  Perhaps he doesn’t know the correct way.  I don’t know.  But no matter WHICH way he does it, he needs to ASK PERMISSION (typically using a checkbox on a setup or preferences or options dialog).

    I dunno… this is VERY suspicious to me.  It’s lighting-up my “could this be malware?” alarm.  I asked, in my email to the author, why a simple screen dimmer needs to access the “DNS/RPC Client Service.”  I’m awaiting his response.

    I’m also going to now send him another email — the one where I tell him that it, indeed, runs on Vista — and I’m going to make the following user interface and behavioral changes to him…

    When one left-double-clicks on the system tray icon to show the main interface dialog (where one may change the brightness, or launch the screensaver, or turn off the monitor, there’s no “x” in the upper right-hand corner to close it.  I realize that simply clicking on anything else on the screen causes it to automatically close, but that’s not the standard of the Windows API.  There needs to be an “x” in the upper-right corner of the dialog; and there should have a separate “options” or “preferences” dialog, and thereon should be a checkbox labeled “Clicking on X closes to tray” so that if the “x” on the main dialog is clicked on, it will close to the tray if the checkbox is checked, and will close the software entirely (exit from it) if the “x” is clicked on when the checkbox is not checked.

    In keeping with the previous paragraph, the software needs its own “control panel” or “options” or “preferences” dialog; and THAT is where most of the settings on the right-click menu (which pops-up when one right-single-clicks on the system tray icon) should reside.  Whether to “auto-start” (which, in this case, means to start when Windows starts) should be a checkbox on a separate dialog where various configuration items are specified/controlled.  As mentioned in the previous paragraph, the at least one other setting which should be on this settings dialog is whether the “x” in the upper-right-hand corner of the main dialog should close the software altogether (exit from it), or simply close it to the system tray.

    The program (iBrightnessTry) should sense whether any screensaver is selected.  If one is not, then the “Screensaver” item on the right-click menu should be grayed-out, and unclickable; and, also, the “Screensaver” link at the bottom of the program’s main dialog should also be “grayed-out” and unclickable.

    Pretty much everything else about the software is excellent.  What I like about it is that it effectively replaces two other tools that I use…

    …the “Display Brightness Gadget” by Samuel Lai, and…

    …the “Dekisoft Monitor Off Utility.”  Of course, the Dekisoft tool has many more features, and can do more things strictly related to turning off the monitor.  However, it can’t dim the brightness, or invoke the screensaver.  If the iBrightnessTray tool would copy… er… I mean… incorporate some of the Dekisoft utility’s features, and also make the changes I’ve suggested, it would truly be world class.

  3. The problem it’s about the power.
    This apps do not work inside the inverter, so the battery decreases at the same time,

    Thx anyway, in my case I use:* DimScreen* Gamma Panel

    • This is not a common amateur app… It actually decreases the monitor brightness natively. 
      Which means it doesn’t use a dark overlay on top of the screen.
      It actually turns down the brightness of the monitor and saves more power that way. (not lower brightness than the monitor can already handle of course)

      Which might be why it only works on windows Vista and 7 or later.
      By the way, I tried this on Windows 8 – works flawlessly!

    • Thanks for your feedback, I will update the info about the compatibility with Windows 8
