OS X :: External Monitor Blank When Set To 1920?
Feb 28, 2010
I have a new LG W2343 monitor capable of displaying 1920 x 1080 connected to my White Macbook early 2009. I have the external set to mirror and have made the laptop display go to sleep by closing the lid and then waking all else up by using the external mouse.
So at the moment the laptop monitor is blank and the external monitor is displaying 1280 x 1024. When I now try to switch the external to 1920 the external screen goes blank too. I then have a blank laptop and blank external meaning I have to force shutdown by powering down.
Why can't I switch the external to 1920?
Any advice gratefully received as I am tearing out what little hair I have left.

Debating between two monitors to use as an external with my MBP. HP LP2475w & Dell 2209WA.
HP is a 24" H-IPS panel with 1920 x 1200 max resolution. Dell is a 22" e-IPS panel with 1680 x 1050 max resolution. The Dell is half the price of the HP.
My concern is the lower resolution on the Dell. What difference is there with the lower resolution of the Dell vs the HP monitor? Keeping in mind of course that the Dell is also 2" smaller than the HP. I'd be using the monitor for extended web surfing, writing for long periods in m.word, and video editing.

The maximum resolution on my brand new 13" Macbook air is 1440 x 900. The monitor I want to buy has a resolution of 1920 x 1080. Can I use this monitor with my Macbook air, and will it look OK?

MacBook Air, Mac OS X (10.7.4), 13" screen

I have a MacBook Pro 13 for portability to my classes at the university and a Dell 2209WA as an external monitor. One of the few good IPS monitors I could find around for cheap.
The monitor works fine in mirror mode with the MacBook Pro, but as an external display only it does not work. It attempts to wake up and then you see power savings mode again and the screen goes black as if there was no connection. Not sure what exactly the problem here is. Drivers?
The monitor works great with a Mac Mini I have and it works great in mirror but not in external display mode(the lid of the MacBook Pro closed). Anybody know of this issue? The cable is good and the MacBook Pro is not that old(a few weeks).

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.

I purchased a Mac Book Pro a year ago.I have been connecting a monitor with HDMI cable but in the past month my monitor screen flickers off then on every few minutes.Eventually it will go blank completely and not come back on.I had thought it was my monitor so I purchased a new one and it still does it. I have connected to my fiends monitors and they do it. Each monitor will act a little different but the end result is the same.My apple warranty just ran out and I suspect its a hardware issue since I can replicate it. [code]

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?

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.

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?

Is there a way to use my external monitor as my only monitor when connected to my mbp? Or, can i clone my display, but at separate resolutions? I am able to do this on windows with nvidia software, is there software that allows further customization?

I have a 22" Dell external monitor on my MBP. I know that I just close the cover to my MBP to shut off the screen. What do I do in those instances that I want to use both screens? There has to be something simpler than restarting the MBP?

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.

I went to the macshop to check out the hi res 15" after reading as much as I could about glare & text size.
(It's a bit like looking at medical textbooks because the more you look round the forums the more problems you find! I have just read about a yellow tint on the 15" high res )
They did not have one in but they did have the 17" high res in.
I know the 17" high res has a slighly higher dpi but does the text size look the same as the 15" high res (more or less)?

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.

I was looking at getting a new monitor (Dell S2209W). It's a 22" monitor with a native display of 1920 x 1080 at 60 Hz. Is this resolution possible with the mac mini?

I have an Intel IMAC, which is now out of warranty as I have had it for 16 months (and I was dumb enough not to get AppleCare). A few days back, my computer would not startup and everytime I hit the power button, I would hear some spinning noise but no chime from the iMAC. Yesterday, I tried it again and this time I heard the chime but the monitor did not start. I was then able to SSH into the MAC and see that it is indeed connected to the network and booted up, but the screen is still dead. Any ideas what I should do before the painful trip to the apple store ?

Okay so, I have an External drive that sat in a USB enclosure until the USB connection snapped off on the inside. I figured I'd remove the (SATA) drive and re-purpose it as an internal drive. When I did this, it shows up as unreadable. The drive itself shows up in disk utility apps, but the two partitions (one was a Time Machine backup, the other a regular Mac-formatted (Extended) partition, do not. I get the ol' "This drive cannot be read. Initialize?" message when the machine boots up. how I can get back to the data I know is on there? Am I gonna have to do a RESTORE to another drive?

I saw a few videos on youtube of the previous revision models and it seemed OK.
So this will run WoW on mediumish at 1440x900? I take it if I connected it to a 1920 x 1080 display in windowed mode it would probably lag?

I am running on an iMac, 3.06 GHZ Intel Core 2 Duo, and it has a display max of 1920 x 1200. I was wondering if there are any workarounds for this? Any apps, or scripts that are safe and will allow me to use a bigger resolution? I am not a tech wiz, but I would love to hear anything you may know of that I can try...

I'm using a temporary monitor while my trusty old Mac HD Cinema Display is in the shop getting fixed.
As a stopgap I am using a Samsung T190.
My computer is a Mac Pro tower. I'm running 10.7.5 (Lion) as I'm still working with Final Cut Pro 7.
I can't get an option to switch the screen resolution to 1920 x 1200
I can go no higher than 1440 x 900.
In my quest for a solution I read something about the option key and the "scaled radio button" in the display preferences.
I don't see a "scaled radio button" in the preferences.
Here's what the Display Preferences look like:

Final Cut Pro 7, Mac OS X (10.7.5), Mac Pro

I've got the older white macbook laptop. Just got delivered was my brand new Dell U2410 monitor (drool) and the adapter from apple that converts mini dvi to dvi-d. The monitor is sitting here and i plug it into my mac via the adapter using the dvi cable provided by Dell and the external monitor displays the default apple background and I can move my mouse around on the screen but that's it. How do I get it to work properly? Do I have to use a separate mouse/keyboard or can I use the macbook keyboad?

I know this is a basic question, but for some reason i just can't seem to figure out how to use my 24" Apple cinema display with my 13" MBP as a second screen. I obviously want to use the 24" display as my main screen (when connected to my 13" macbook) but for the life of me I can't seem to figure out how to use my MBP as a secondary iTunes, etc. screen. I typically use my macbook in "clamshell" mode with my 24" display and when I open the lid of the macbook, it's just black as if the computer was asleep but it fails to wake up when I press any buttons on the keyboard . When I unplug the mini display cable, the external monitor goes black and I'm reverted to using just my macbook. I know this can be done. Does anyone have any experience with the 24" Apple cinema display and MBP?

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 last years model. I use external monitors alot for video DJing. I normally go DVI to VGA using the adaptor that came with the MBP. The other night I tried a different adaptor- DVI to composite. Now when I go back to the DVI to VGA my external screens have a yellow green tinge to them. I bought a new DVI to VGA adaptor and that didnt help. I calibrated the color profile, detected displays. and still the external screens are a yellow green color. You can still see whatever Im playing but there is definately something wrong with the color.

I need the menu bar on my external monitor for PS and the like, but I'd prefer to the have the dock visible without it cluttering things up, so it'd be great if someone knows how to isolate it to my other monitor.
