External monitor resolution setting is not saved

I use an external monitor as an extended desktop for my macbook pro.
The problem is that whenever I turn on the mbp, the resolution of the external monitor reverts back to the default resolution. Is there any way to set the resolution of the external monitor and have the mbp save it even after turning the mbp on and off?

Hello all,
After installing the 10.5.2 update, my Macbook Pro's boot time increased. So, after researching this issue, I decided to reset the PRAM. This solved the boot time problem, as my Mac now boots as quickly as it did prior to the update. But now, the brightness setting is not saved and the brightness level returns to the maximum value each boot up. Other settings, like audio level, are saved properly. The brightness seems to be the only problem. Any ideas on how to correct this?
Thanks,
Anthony
Besides staying with 10.5.1 has anyone found a real solution to this? I want to install Aperture and I need to have 10.5.2 installed in order to instal Aperture v2.x.
Thanks!

1680 x1050 external monitor on T500 does not work

Dear all, I have a T500 running XP professional and a Philips external monitor 220BW8plus, but when I set the screen resolution to the screen's native resolution my screen gets compressed with 2 black areas on the side. I've tried everything I could think of, but nothing worked. Now I'm forced to work at 1400 by 1050.
Does anyone know how to solve this?
Thanks for any suggestions.
Cheers,
Erik

Thanks for that suggestion, but I've tried that and as soon as I apply that change, the screen gets compressed with big black bars on the side.
It doesn't matter if I switch to single display, dual clone, dual extended, without or with docking station. I've updated to the latest software drivers etc, etc.
Is it a problem of the T500 with this brand and type of screen (Philips 220BW8CS1/00)?
Even our IT department is not able to solve the problem. They suggest I'd buy a different screen

Est. external monitor resolution

I am trying to set up a samsung syncmaster 191Tplus as an external monitor on my macbook from early 2008 running 10.6.8. When I plug it in, both screens flash (not just a flicker) as shown in this youtube video posted by someone else, but my problem is the same
http://www.youtube.com/watch?v=2-Yz-Em2GU4.
I am using the mini-DVI to VGA adaptor. The resolution of the samsung is 1280x1024, which is not listed in my choice of display resolutions. Is this the cause? What can I do? I can't access settings to change anything after the monitor is connected, and I can't find settings for the external monitor before it is connected. Would using SwitchResX work to create a monitor resolution preset before plugging in the second monitor?

OK, here is something to try. Go into System Preferences and select Displays. In the window that opens will be a checkbox for "Show displays in menu bar." Put a checkmark there and make it active. There should now be a little icon of an Apple display on the right side of the menu bar at the top of the screen. If you click on it, it will drop down and give you a short cut to different resolutions. There should be a checkmark next to the currently active resolution. Is it set to 1440 x 900? If not, set it there.
If you are still getting that message from the monitor, well, I don't think the Mac is lying about sending 1440 x 900. If the screen doesn't look right to you, try using the Auto Adjustment feature on your Viewsonic monitor. It could just be that the image needs adjusting.

Low external monitor resolution

Hallo, I've the Macbook AIr 13" (2012) with an external Samsung Synchmaster XL 2370 LED monitor. Unfortunately, the screen resolution of the 1920x1080 Samsung monitor is not at 1920x1080, but lower. The Mac OS 10.8.1 uses the profile HD 709-A. This cannot be the correkt profile. Does anyone have an advice?

Are you using mirrored or extended display mode. If mirrored then the resolution of the laptop will also be mirrored. If using extended mode you can set the resolution of the external monitor differently than the resolution of the laptop. And try to toggle the resolution in System Preferences>Displays.

External monitor resolution problem on MacBook PRO

In order to get the external monitor's native resolution uncheck use mirrored mode in your display preferences. If you are using mirrored mode then your computer's display, including its resolution is used on the external monitor,

External monitor quivers on L440, not on Acer

Hi there,
My external monitor quivers when connected to my new Lenovo ThinkPad L440. I does not do it when connected to my 4 year old Acer laptop, is seems perfectly fine there. In both cases connected with the same VGA cable.
It's a constant, tiny flickering, as if every pixel jumps left and right all the time. The external monitor is pretty old, approx 8 years...
Any idea what it could be?

Are you using a ThinkPad Basic Dock in this configuration? There is a new update available that resolves flickering or black screen on external monitors for the Dock.

Lenovo X201 external monitor resolution issue

Hi,
I'm having issues connecting my Lenovo X201 through the docking station -> display port -> Dell 3011. The native resolution for the monitor is 2560x1600. However, I currently can only set the resolution to 1920x1080 (ugly!) as any high resolution results in the monitor entering power save mode.
I'm using xrandr to set the video mode in my .xinitrc (running dwm). This creates a good Xinerama config for dwm.
I'm currently using the line
xrandr --output DP1 --mode 1920x1080 --above LVDS1
to set my resolution. When I change to --auto or --mode 2560x1600, or 1920x1200 etc I get the blank screen on the external monitor. I'm using the xf86-video-intel-sna driver package (I tried the -uxa as well to no avail).
Any hints?

I was able to get it by having arandr help generate the config, here's the solution that worked for me:
xrandr --output HDMI1 --off --output LVDS1 --auto --right-of DP1 --output DP1 --pos 0x0 --rotate normal --auto --output VGA1 --off

External monitor resolution problems with Mountain Lion

I have a problem with my external monitor (Samsung LS19B150NS) and Mountain Lion (running on unibody Mac Mini). Each time I reboot OSX the resolution get reset from native 1366 x 768 to something lower. The display is connected via DisplayPort-to-VGA adapter. Some observations:
- I tried selecting "Best for..." option or "Scaled" (set on 1366 x 768 or 1360 x 768). The problem is still there
- Sometimes resoltuion might stay alright for several reboots, but then the problem re-appears again
- Sleep mode doesn't reset resolution
- Other monitors work fine via the same adapter
- The Samsung LS19B150NS work perfectly well with other Win PCs
Any suggestions how to fix it?

ITunes changes external monitor resolution (permanently!)

OS X 10.6.8
MBP 2010
External Monitor NEC 2690WUXI (1900x1200), DVI via original Apple MiniDP to DVI port
Since last night, whenever I start iTunes, the external monitor goes into 720p mode and I need to delete various plists, clear caches (OnyX), turn off, reset SMC and PRAM etc in order to have the option to get 1900x1200 resolution again. Then the moment I run iTunes, the monitor settings are lost and it is treated like a 'TV' again.
Please help, this is $#"$#" driving me insane, that my expensive, pro level, color corrected monitor is not being detected correctly anymore (it has worked for 24 months)

This is driving me absolutely fuc****g insane.
My double monitors are switching back and forth, the resolution is changing, they are flickering on and off, sometimes they are going off totally and I cant get anything back on the screen without shutting the entire computer down.
If this is caused by i-tunes (which I think it is since the problem started on the date that I updated the program), then it is an ABSOLUTE OUTRAGE. You should write individual apology letters to every single one of your users who you have made undergo this time waste and mind screwing.

Thinkpad tablet 10 maximum external monitor resolution

Hi,
The max resolution that I'm getting on the external monitor either using the docking station or the micro HDMI port is 1920x1080. The native resolution for the touch panel is 1920X1200.
1. Is there any way to get alo least 1920X1200 on the external monitor?
2. If not, what could be the technical reason if the video card in theory supports even more than 1920X1200.
Thanks.
Solved!

I'm afraid that this limit of resolution looks to be by design; the Lenovo spec in the PSREF documents state:
"Intel HD Graphics in processor, supports 1080p video out via micro-HDMI connector, HDCP-compliant"
The Intel Atom chipset used in the TP10 apparently doesn't deal with higher resolutions than this. See:
https://communities.intel.com/thread/55056?start=0&tstart=0
Baytrail processors from the Core range can go to higher resolutions, but I don't think that this applies to the Atom architecture.

U110 How to Retain External Monitor Resolution

I'm trying to help someone with an IdeaPad U110 and an external monitor. The Lenovo allows me to login with an external keyboard and monitor but as soon as it boots Windows, the external monitor goes dark and I have to choose FnF3 each time to re-enable the external monitor and then reset the resolution to 1680 X 1050. Isn't there a way to get the Lenovo to retain these settings so I don't have to do this each time I boot it up? THANKS!!

Hi JLNH,
Welcome to Lenovo Community Forums!
Please try these steps.

Please help me with external monitor resolution! Now!!

So i just bought a 22' Acer monitor to use via a VGA adapter with my xbox 360 (to get weak HD in time for Halo 3). I also own a MacBook Pro (the latest Sata Rosa one) which has an Nvidia GeForce 8600M graphics card with 128 VRAM. To my dismay however when i plug the monitor into the MacBook Pro via the DVI to VGA adapter that came with it i find the screen resolution to being very low, almost standard definition. I have fiddled with the settings and everything and found the best resolution is to have the MBP on 1440x900 and the Acer monitor on 1680x1050at 60Hz but its still shoddy resolution. Please could anyone shed some light on the subject? The funny thing is though, when i boot into Windows via Bootcamp, the monitor looks alot better (but still not good enough) and i have far more settings to adjust via the Nvidia control panel. Please help me with this because i only have a few days to decide wether or not I should take it back. Thankyou.
Here's the monitor with some specs: http://www.pcworld.co.uk:80/martprd/store/pcwpage.jsp?BV_SessionID=@@@@0884756254.1190642998@@@@&BV_EngineID=ccggaddmdfmkflmc flgceggdhhmdgmi.0&categoryoid=-27763&sku=774215&page=Product&fm=null&sm=null&tm=null

I have a similar problem. New Macbok Pro with an Nvidia card and an external monitor (HP f2105) 21 inches max resolution of 1680x1050.
My issue only happens via Boot Camp on Windows Vista (it's fine in OS X and Paralells).
I previously owned a Macbook and the external display was at max resolution, now, I only get a non-modifiable 1024x768 option on the HP display...
Don't know what to do, no info on Nvidia or HP forums... I assume it's a driver issue. COuld it be that a HP driver for the display itself help? Do drivers for displays actually exist?
Sad that the Macbook Pro does not comply as well as a normal Macbook.

Wrong VGA monitor resolution set on desktop

How can I change the monitor resolution before start commences. The resolution that the desk top is set for will not display on my monitor and therefore I can not reset it. I need to interrupt startup to reset the monitor resolution before it sets up the desk top. How can I do this?

You can boot into safe mode (hold down Shift key during bootup until you see the spinning gear) which will force a generic, low resolution (SVGA I think) which should work with most any monitor. However, I don't know if you can alter resolutions from safe mode and have them stick during a normal boot. Good luck.

Question About External Monitor Resolution

Can my external monitor's resolution (such as 1920/1200) connected to my macbook be higher then the 1280/800 my computer has?

The problem with running in mirrored mode is that the external display will be limited to a set of resolutions that match the aspect ratios that are supported by the MacBook's internal LCD. This means that you will end up with a limited set of resolutions on your external display and it may even be impossible to select the optimum or native resolution for your external display (when running in the mirrored mode). However, when you disable mirrored mode you should be able to select any resolution that is supported by the external display itself (as reported by the display hardware). However, there have been reports of users having problems with resolution settings when they connect a display using HDMI, since in some cases that appears to default to a maximum resolution of 1920x1080, which is the standard 1080P for HDTV.
