When I connect my 13" MBP to an external display to watch a movie etc. the external display seems to be darker than it would appear if I was watching on my MBP. Is there anything I can do to make things brighter (other than turning the brightness up on my TV)?
View 1 RepliesI use my MBP hooked up to an NEC display with an Apple wired keyboard. Is there any way to have the F1/F2 keys still control the brightness on the MBP display? They currently don't do anything.
View 1 Replies View RelatedI have a MacBook Pro 13'' (mid 09) and another MacBook pro 15'' (early 09). The problem below applies to both of them.
I often use my 15'' mbp connected to a usb keyboard, mouse, display etc. Basically it is used as a stationary computer that can be easily moved (to work/school etc). This is my main laptop so this is where I noticed the problem first. Sometimes when just using the computer as normal (using itunes, opera, adium etc) the OS X will just suddenly become very sluggish and unresponsive.
However it is not OS X itself, but the GUI! Example: if I move my mouse over the dock, it wont animate. If I try to do any finder related action the GUI response is way of and if I try to do something in the menubar I have to hold left click, if I let go it just closes the menu.
This goes for the application folder as well (I have it as a list). Normally it will just funtion as normal but when this problem occurs I have cant let go of the mouse button when moving through the menus because then the menu closes!
WITHOUT closing the lid, because i like using the touchpad. i know that you can turn the brightness all the way down, but sometimes windows from the main screen randomly open on the other display. and it also slows down performance. i want to turn off the 13" screen as if the lid was closed. that way, the mac doesn't even see it.
View 5 Replies View RelatedWell my unibody macbook display decided to screw up last night, it was working fine last night no problem. Connected to a external monitor. I fell asleep last night with front row left on, obviously it went to sleep and then I woke up and the screen was black. Now the LED lights are working, my external display is also working. The display settings recognize a screen being present (when I click detect displays and gather windows - 2 windows appear). Ive reset PRAM, SMC, reseated the RAM, control+shift+eject (which just made the screen flicker a little after turning it back on) and Im out of ideas. Its out of warranty and about about 18months old.
View 4 Replies View RelatedI have a Late 2011 MBP, just recently I also go an Xbox and wanted to hook it up to my external display that I have been using for a long time with no issues. I went and bought this: URL....to be able to easily switch between the two inputs. The xbox works fine, however when I view my Macs input the screen flickers a static image very frequently.
I know what you're thinking, it's probably an issue with either a cable, or the device. But when I boot into Windows via Bootcamp with the same exact setup, there is no flicker at all. The display is a dell s2440L, the HDMI adapter is a rocket fish.
Here are the troubleshooting steps I have tried: Resetting PRAM/SMCChanging out HDMI cables on both the Splitter output, and the inputs (I tried 3 different cables on both the inputs, and outputs.)Downgrading OSX to 10.7 (And then went back to 10.9)Lowering the resolution on the monitor (Lower resolutions flicker just as much, if not more.)Resetting the splitter by unplugging the HDMI cord powering it and plugging it back in.and of course, plugging my computer into the splitter input that the Xbox works fine on, as well as taking the xbox one out so the computer is the only input on the splitter.
Like I said, the Xbox works fine, and even the computer works fine in Windows, but whenever I boot into OSX my screen flickers with this static. I should add, the display works fine when not connected to the splitter on OSX.
I bought a MBA 13" last month and now I'm trying to connect an external monitor through a Mini Display Port-to-HDMI adapter and most of the times the display shows a message "No signal detected"...
I've tried all the possible combinations between the MAC and the Monitor but it would seem a random matter.

MacBook Air (13-inch Mid 2012), Mavericks 10.9.4
I use my MBP connected to a Dell U2410 and everything has been ok for the last 5 months or so (I got the MBP around the beginning of Feb.). However recently, my display will start flickering (blinking) a blue screen up to the point that it is completely unusable. Often if I simply unplug the mini displayport from the mbp and plug it back in again, everything goes back to normal for awhile. Just now I was able, between flickers, to switch from the integrated graphics card to the dedicated (?) graphics card. Although I did get a few flickers logging back in, so far it's been ok.
View 1 Replies View RelatedI have a 2009 Mac Mini connected to a 22" LG monitor via Mini-DVI port and it's also connected to a 50" Pioneer Plasma (in the next room) via Mini-Displayport. Everything works perfect except that when I turn off the Pioneer Plasma, my mouse can still scroll over from the LG monitor to the Plasma.
I've also noticed that my screensaver is laggy even when the Plasma is turned off (usually that happens when it's drawing the screensaver on both screens) so it must still be sending a video signal out of the Mini Displayport.
I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything
View 9 Replies View RelatedI have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?
I found the setting under Displays to automatically adjust brightness, but is there a way to set this different for Battery or Power Adapter? I would like to keep this option on for using the Battery, but would like the display at a constant level when using the Power Adapter.
View 3 Replies View RelatedRecently, after about 5 minutes of use (not sitting idle), my MacBook's screen will go very dim. I hit the buttons on the keyboard to take the brightness all the way up, but it doesn't get much brighter and there's only one thing that I can do to make the screen go brighter: I go into System Preferences and click Display. The second I click that, the brightness returns without me doing anything in the Display section, so after Display comes up, I just close it out and the screen brightness is fine for a while. It seems to do this after the lid has been closed for a while and then starts dimming again after opening the lid and using it for about 5 minutes. Is there a way to fix the auto-dim mode without disabling it? MacBook (white) is running Leopard 10.5.8 with all the latest updates.

View 2 Replies View RelatedBasically what I want to do is sync my Apple Cinema Display's brightness with my MacBook ambient light brightness control. So when the brightness of my MacBook changes because of ambient lighting, my secondary monitor changes with it. Is this possible? Is there a software that does this?

View 2 Replies View RelatedThe reason I am asking is that I am using a Spyder colorimeter to calibrate my monitor and it is asking me which controls exist on the display:
-brightness
-contrast
-backlight
My thinking is that F1 and F2 control the backlight level and not the "brightness" level, if you get what I mean.
Just had apple replacing the display on my rev b air due lose hinges, I think this new display much brighter then the old display. It is just a psychological thing? or does the screen actually losses brightness over time/usgae?

I have an external monitor (Samsung 2223w) monitor connected to my MBP via DVI. The MBP is shut.
Is there a way that I can reduce the brightness of the external monitor quickly with software? Of course, I can manually reduce brightness by clicking the buttons on the side of the monitor and navigating through the menus. But is there a way that I can set a keystroke to do the same?
I am looking to purchase an external monitor for my unibody macbook pro, and I love the (maximum) brightness level on it, and would like the same on my external monitor. Does anyone know what the cd/m2 rating is?

MacBook Pro with Retina display, iOS 7.1.1
The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.
I have setup the 23i cinema display with mac pro. I have connected the USB and firewire cable to mac pro.. and keyboard is attached to back of the display. For some reason I cannot seem to adjust the brightness of the display from the keyboard (though I can do it from the side of the monitor). Neither can I see the brightness slider bar in the display settings. Also while the display is the the power led in the front blinks 3 times, then there is a little pause, and blinks 3 times again. How to fix this brightness control issue with the display. I have reseted PRAM and NVRAM... still nothing has changed. Also note I do not have and options tab for some reason.... (I have tried to plug the display's usb into the back 3 usb of the Macpro... still nothing)
View 1 Replies View RelatedI have a 24" LED Cinema Display and can no longer control the brightness settings in OSX I believe when I applied the recent java/bluetooth updates the slider disappeared upon reboot. I did some searching and can't come up with a way to get it back. I'm using a 15" Unibody MBP, and the brightness slider for that screen is available and does work. I also tried setting the keyboard shortcuts on my main keyboard (external) to turn up/down the brightness but they won't function at all.
I have tried zapping the PRAM, repairing permissions, and disconnecting/reconnecting the display, as well as booting with no external display and nothing has made the slider reappear. I also logged-in as a different user and the slider is not there for the Cinema on that profile either. I really, really hope I don't have to reinstall OSX to get rid of this but I'm out of ideas. The worst of it is that I turned down the brightness to less than half (when it worked) becuase I had a headache and now it's stuck there!
I have just realised that the Brightness slider in Display Prefs on my Mac Pro is missing. Running SL 10.6.2 with an Apple 24inch ACD connected.

I have a 19-inch Envision EN9410e LCD flat panel monitor. Right now I did a mirror display setup. The native resolution of this monitor is 1280 x 1024. When I went to System Preferences to change it to that resolution my LCD monitor shows the Snow Leopard desktop but it's in the middle of two black bars. I had to revert to 1024 x 768 resolution to not have the black bars show. Is there a way I can change it to the native resolution and not have the black bars on the top and bottom show up on the screen?
