I have a Surface Book with a LED Cinema Display connected. Everything works fine except that Windows does not let me control the brightness of the external monitor.
If I use 'Extend these displays', the 'Adjust brightness level' is greyed out. If I show only on the external monitor, the brightness slider becomes available but has no effect. In Device Manager there are two display adapters: 'Intel HD Graphics 520' and 'NVIDIA GeForce GPU'. I presume the first one is for the internal Surface display and the second one for the Cinema Display. Under monitors in Device Manager there are two: Generic PnP Monitor and Surface Display. 'Generic monitor' doesn't sound very convincing to me.
Should it not be more specific for the Cinema Display? A surface book is a tablet, which is irrelevant when the heading says EXTERNAL monitor.
And no, there obviously aren't any buttons on LED Cinema Display monitors, otherwise I wouldn't have posted this message. By the way, by spending hours searching the Internet and doing some serious 'hacking' I have now managed to control the brightness on the external monitor. Not thanks to this forum or Microsoft's audacity to offer paid support for something as simple as getting a £2500 computer to control the brightness of an external monitor.
Ok.sorry for asking a STUPID question apparently. The person who owns it is LITERALLY dying w/ Stage 4 cancer and is too weak to even function (no such thing as Stage 5). I work for him and am using it to save his life.so.sorry if I don't have anymore data for you. I just unplugged it and held it upside-down (HUGE & HEAVY; almost dropped it) to take a pic of the bottom of the stand it is attached to, w/ my cell to give u LITERALLY the ONLY printed info on it.can ONLY upload a 2MB pic (my Samsung Galaxy 5 Note can't take a pic w/ that low a resolution) so I can't attach the pic.
Note that the brightness level adjuster might not appear if you’re trying to adjust the screen brightness of a monitor connected to your PC. Method 4 of 4. Use Control Panel to adjust brightness in Windows 10. This is the classic way to manually adjust screen brightness in Windows 10.
Here is what it says: 'Designed by Apple in California Assembled in China Model Number: A1267 EMC Number 2263 Rated 100-240V- 50-60Hz, 3-1-2A. Complies with Canadian ICES-003 Class B specifications. Apparaten skall anslutas till jordat natuttag. TM and @ 2008 Apple inc. Cupertina, California 95014' And if that's NOT enough data for you.then I don't know what to tell you. I DO appreciate yours and all others time, who have or will, help me with this question. I'm NOT trying to be rude.
This is LITERALLY a life or death situation! Any and all info anyone can give me would be GREATLY appreciated! From the manual - Adjusting the Color and Brightness You can use your Apple Keyboard to increase ( ) or decrease ( ) the brightness of your display. You can also use System Preferences to adjust the resolution, brightness, and color settings. To adjust the resolution, the number of colors, or the brightness of your display: 1 Choose Apple () System Preferences, and then click Displays. 2 Click the Display tab.
3 Choose a resolution or color setting, or drag the Brightness slider to adjust the brightness. To change the display profile or calibrate your display: 1 Click the Color tab in Displays preferences. 2 Choose a display profile, or click Calibrate to open the Display Calibrator Assistant.
For more information about calibrating your display, choose Help Mac Help in the menu bar, and search for “calibrate Thus try what I bolded above. Illaass response should do the trick. I could not find that quickly on my own. I will follow the steps she outlined with my MacBook Pro (the KEY to the ENTIRE matter) Thus, the monitor was actually irrelevant: I have NO way of doing ANYTHING on it.it is SIMPLY a monitor. EVERYTHING is controlled by the MacBook Pro I am using with it for ALL input.
Which is why I did NOT go into detail about it.especially since I did NOT buy it or know the history of it. Anyway, I VERY MUCH appreciate your valuable time. Thanks again! Apple Footer.
