MacBook Pro :: Reduce Brightness On External Monitor With Software?

May 18, 2009

I'm sorry if this is a dumb question. (I feel like I know a decent amount about my MBP and about a/v matters, so, I feel a bit dumb for not knowing the answer to this.)

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?

IMac :: 2nd Monitor Brightness?

Nov 26, 2010

I have a 27 iMac, and a 22 inch Viewsonic as the second monitor.

The second monitor is just not bright. I have used another monitor as a second monitor as well. Both are just not bright enough to suit me.

I have fiddled with the brightness controls, to no avail.

Is that a generic problem with second monitors?

They just don't get enough juice or something?

Would another brand monitor help?

MacBook :: Using External Monitor With New MB (2.4GHz)/monitor Sleep?

Oct 16, 2008

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.

When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.

My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

MacBook Pro :: Detects An External Monitor But No Display On The Monitor?

Aug 5, 2009

As said, my current set up is an HDMI - DVI cable (HDMI to monitor and DVI to adapter) and my DVI - mini DisplayPort adapter, everything is connected fine but when I turn on the monitor, it says cable not found... and nothing is displayed on the screen but on the Macbook side of things, it sees the monitor is connected (I can extend the screen and leave the screen) but other than that, it appears I cannot get an image on the monitor, pressing every button on the monitor does not work either.

Any other information that may seem necessary, let me know. I tried clearing my PRAM and clearing the power and such but nothing seems to work.

IMac :: External Monitor - Bad Mouse Tracking When External Monitor Off?

Jan 9, 2010

I have a 27" i7. I have a 24" DVI Montior hooked up to it via MDP->DVI adaptor. When the 24" Monitor is on, everything is fine. When I turn the monitor off, the magic mouse tracking on the 27" screen stutters. I am not kidding - it took me ages to figure out that to fix I either need to turn the other monitor on OR disconnect the MDP->DVI adaptor.

IMac (Intel) :: Change Display Settings Such As Color Temperature And Backlight Brightness On Monitor?

Nov 30, 2014

My wife has an iMac (I don't know any other way to identify it e.g. model number), and she has this 3rd party calibration software that I'm trying to use. I am not used to a Mac, and I cannot find the display settings for the monitor. There are no buttons on the monitor, and when I go to preferences, I can only find the brightness control. I've googled this and cannot find a clear, simple answer. I have used every version of Windows (currently on 8.1 on my PC) and it's easy for me on that platform. I suppose it's just that I don't really know how to navigate Mac OS.

iMac, Mac OS X (10.6.8)

MacBook Air :: Unable To Adjust Screen Brightness / Brightness Goes Up And Up

Nov 15, 2010

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.

Hardware :: Powerbook With Broken Monitor - Force Boot To External Monitor?

Jan 31, 2010

I have a G4 powerbook with an LCD that only displays the top 25% of the screen. I've been using an external monitor with it just fine. Today, I reinstalled the OS and ran into a problem. The main OSX startup menu (you know, where it asks for your location, timezone, personal info, etc) is prompting me for information, and I can't see the forms to fill them in! The external monitor defaults to "extended" as opposed to "mirrored", and the forms are embedded, meaning I can't drag them over to my external monitor. Obviously, if I can't fill out these forms and get to the desktop, the laptop is completely useless.

Does anyone know how to force the external monitor to be "mirrored" from startup? Is there a keycommand?

OS X :: Monitor Suddenly Goes Completely White / External Monitor Goes Black

Jul 30, 2005

I have been using the latest macbook pro 13.3" since April 2010. Over the last week the monitor suddenly goes completely white and the external monitor goes black. The laptop becomes unresponsive although the programmes opened continue running (e.g a skype voice call would continue without interruption although the monitor is all white).

The only solution at the moment is to press the turn off button for a few seconds then switch the laptop on again. It will then work normally until for no apparent reason this happens again.

OS X :: Volume Opens The Window For Expose And Does Not Control Volume Monitor Brightness?

Mar 9, 2010

Recently, my newer (last year) iMac probably running 10.5 started speaking and wont shut up... there is no obvious way to turn it off. I usually figure problems out myself but there are no system preferences that effect it. I even changed the voice in preferences as a test and it is still the same guy reading everything clicked in all applications except when I am in system preferences so far. Usually when I run into a dead end like this there is some mystery key command that works... anyone know?I also noticed that some of the top line (f) keys are not doing what they are supposed to any longer as well... volume up opens the window for expose & spaces it looks like and does not control the volume monitor brightness controls are not working either... I went to the key and mouse preferences and set the key strokes to default and still the same.

OS X :: Lag With External Monitor From MacBook Air?

Dec 1, 2010

I have my MacBook Air hooked up to a 46" HDTV so that I can play games on the big screen.

Problem is, I notice a slight lag with the mouse when looking around in the game on the big screen.

When I look at the game from my MacBook Air there is no lag with the mouse.

I heard theres a mode called "clamshell" that would fix this but don't know where to find it or enable it.

Info on fixing the lag from the big screen so that games could be playable when watching from the big screen.

MacBook Pro :: Using An External Monitor With It, How To Set It All Up.

Feb 1, 2012

I got a fairly nifty AOC 16" USB monitor from isn't totally Apple-Quality, but its bright... looks decent at 1366x768... and I got the color of the windows to almost completely match. I would suggest the AOC USB monitor to anyone looking for a cheap way to get a 2 monitor setup. And, it runs from a USB port only... no need to plug it in. Very nice. One drawback of this model is that it does have protrait AND landscape modes... there is a stand on the rear that you twist and can stand the monitor up on its end. However, the Mac drivers don't support this feature! Shucks! I had grandure thoughts of having a document in portrait mode all tall and beautiful. OR, a killer long Facebook window. But alas, this feature will have to wait for now... man, if AOC can release a new driver with this feature; I would say this $140 monitor is a KILLER. Still reccommend it.

First, when I connected it the monitor was aligned or setup on the left hand side... I want the NEW 16" monitor to be on the right hand side just as an extra screen space... so, I opened displays and moved the alignment. I noticed you can go up down left or right... which is cool. So I set it up for the right hand side, so when I scroll off the MBP screen to the right the cursor just goes over to the new screen. Great. However, the dock and toolbar are on the NEW 16" monitor no matter what I do! I want the dock and toolbar on the MBP still; and the new monitor just sitting there ready for me to throw any STUFF on it. How do I do that? 

Also, when I use that multiple desktop feature... lol, I forget what its called. Each desktop switches the new 16" monitor to whatever # of screen I'm on. I can live with that if its the only way. BUT, better for me would be if the MBP has the dock and toolbar... can switch between those different screen #s... AND, the new 16" just sits to the right as extra space. So when I switch screen #s, the new 16" stays the same with whatever windows I have open staying there... this might not be doable, and that would be OK... but wondering if theres a way to do that too...

OS X :: Unable To Show 10.6 Install On External Monitor / Grey Box On External Display With Black Bar

Feb 27, 2009

I have a Macbook Pro 2.16 Core Duo, and I'm wanting to install 10.6, but about a year ago, I cracked my screen to the point that I cannot make anything out on it, and haven't replaced it. Instead, I have just been using it in clamshell mode, which has worked out fine so far. My problem is that I cannot get the 10.6 install to show up on my external monitor.

I searched around, and could only find one other similar thread that just ended with the author putting it in clamshell and having it work fine. When I boot to the install and close the screen, I just get a grey box on my external display with a black bar on either side of it. I can't seem to find any other resources, so I'm not entirely sure what to do at this point. Any help would be greatly appreciated.

MacBook Pro :: Adding Second External Monitor For Use In FCP

Sep 18, 2010

I'm running an older 24 inch cinema display on my MBP and am looking to add second 24 inch monitor for use in FCP. My only cheap option seems to be a USB gizmo, something like this [URL]. Anyone have any experience with this device, specifically with FCP 6; I'd like to use the second monitor to playback the footage in the viewer so I don't think the device needs too much horse power but the footage will be in the ProRes 422 format.
