Menu
The screen is far too bright and I am at a loss as to how to change the brightness. I tried to download HP software for the monitor but I cannot seem to find a download for my Mac, only Windows. Any help would be greatly appreciated!
Update - 2015-10-30 ScreenBright seems discontinued, but as suggested, might be an alternative. The solution I am using right now I found enable DDC/CI option in my displays' settings. The program was able to modify it, although I think it's GUI is quite terrible and easy to break you custom settings. My screens also flicker a lot when changing brightness. Nevertheless, it has a commandline interface, which is much better. Especially when you create your own GUI (which is around 5 minutes in C#) or use plain Windows shortcuts.
Old setup As a side note to the Dell brightness change - I can confirm that it also did work for me. My setup was:.
Dell Latitude laptop (5520 I believe). Dell Docking station (the extended version).
2xDell u2412m screens, connected via DVI The laptop itself had a built-in GPU (Intel HD2500). In its software there was a tab called 'monitor settings', iirc. It did indeed communicate with the displays and somehow change their built-in brightness settings.
I weren't able to do much more (change profiles, for example), and it took quite a while to 'initialize'. There was also a 2-3 second delay between the setting of the brightness and actual change. I guess it was mostly due to the screens, which changed brightness gradually. I've updated my PC to the regular workstation, and unfortunately I wasn't able to find similar setting in the NVidia control panel. EDIT: It seems that my previous setup used. A tip: You can create shortcuts in the Start menu and then edit them to add command line arguments like -set brightness 10 contrast 50 and to assign hot keys to them. (That's a standard Windows shortcut feature.) I'm switching like that between my 'profiles' (each is an icon in the Start menu).

And yes, it takes a few seconds until it adjusts the screen, but it's still much faster than doing it trough those horrid monitor menus. BTW, never understood why no monitor gives us a few plain physical buttons that can be associated with my custom settings in the monitor's menu. – Nov 29 '14 at 12:34. I found ClickMonitorDDC from a recommendation on Superuser: softMCCS from ddc-ci.com allows lots of control but it's too low level technical for regular use. Just to control brightness and contrast I'm using (Windows). Answered Mar 15 '15 at 23:09 aland ClickMonitorDDC is a portable freeware tool to adjust brightness or contrast of a DDC compatible monitor It's the most user-friendly application that I've tried. You can quickly jump to any brightness and contrast number that is a multiple of 5, and then finely adjust.
There are also hotkeys, and command line commands. B20 c30 Brightness 20 contrast 30. ClickMonitorDDC also allows you to jump to a volume.
With the default Windows 10 volume control, it's hard to see the exact volume number that you will jump to. ClickMonitorDDC has 20 volume buttons that are each a multiple of 5, and they go from 0 to 100. I also tried this recommendation in combination with ClickMonitorDDC: Flux v3.10 has additional functionality to control actual brightness using hot-keys Alt+PageDown and Alt+PageUp. Answered Jun 25 '14 at 17:25 Karan Flux is a filter, and it can get you darker than ClickMonitorDDC and your monitor will by themselves. EDIT: April 24 2018 I've noticed that ClickMonitorDDC might not work on all monitors. Alternatives include Desktop Dimmer or PangoBright.
Are you talking about an external monitor or a laptop's built-in display? An external monitor's brightness is almost always controlled externally by the monitor, there just isn't any way to pass brightness settings information over any of the usual display connectors (VGA, DVI, HDMI, DisplayPort, etc.). A built-in display on a laptop or all-in-one however has its brightness control integrated with the system, and can be controlled from within windows by some software. The actual software to do so will depend on the manufacturer. Windows 7 can do it automatically from the Windows Mobility Center (press Win+ X), but in Windows XP you will need the manufactuer's drivers.
I have a Surface Pro 2 with Windows 10 that I connected via the Mini DisplayPort to an Apple LED Cinema Display 27' from around 2010-2011. The display works, but the brightness control in Settings - System - Display is grayed out, and hence I have no way to set the brightness.
Moreover, I can only control the screen resolution (Settings - System - Display - Advanced Display Settings) if I select 'Extend displays', otherwise the option is grayed out. I tried to google a bit (it looks like I need drivers for the monitor), but couldn't find anything meaningful. Moreover, I can only control the screen resolution (Settings - System - Display - Advanced Display Settings) if I select 'Extend displays', otherwise the option is grayed out. This is normal behavior, your screen obviously can't be mirrored, yet rendered at different resolutions, so if mirroring is chosen, the screen is rendered at main displays resolution. Resolution control is going to be available in extend or 'show only on display X' mode.
Getting brightness controls is going to be a pain, try starting with this tool (recent win10 info is in the comments).
