MBA and 30" LG External Monitor Resolution Issue

Hello!
I own a LG 3000H monitor (HUGE 30" 2590x1600) that I use with my windows desktop computer for video editing and it is an amazing monitor. I wanted to use it with my Macbook Air Summer 2009 (2.13Ghz, 128GB SSD, Nvidia 9400M) as an external display. I bought the Mini-Display Port to DVI adaptor and hooked it in to the monitors DVI cable and the resolution won't go higher than 1280x800 (the same resolution as the MBA's display). I tried everything I could think of and it's not working. I called Apple Care and they didn't do crap after an hour on the phone so I was wondering if anyone here could suggest anything. I also have the Mini-Display to VGA adaptor so does anyone know if I get a VGA->DVI adaptor would that work? (because the monitor only has one Dual Link DVI slot as an input) I'd really like to use this monitor! Thanks!

Hi,
to use the full resolution of that monitor, you have to use a Mini DisplayPort to Dual-Link DVI Adaptor like this http://store.apple.com/us/product/MB571Z/A?fnode=MTY1NDA5OQ&mco=MTA4MzU1ODY
(According to the MBA tech specs http://support.apple.com/kb/SP548 )
Using the BGA-port of that monitor will not bring up the full resolution of it.
Plus for the full resolution you have to set the display settings of the MBA to "Extended Desktop" not "Mirrored".

MBP external monitor resolution issue

Hi, im having issues with my 2010 MBP 13 inch, which has an Nvidia 320M,
Ive installed Windows 7 32 bit, and connected a Hanns G HG216D external monitor thru a mini display port to VGA connector.
The problem is that the maximum resolution i can get is 1024x768, i cannot choose or create the native resolution of my monitor which is 1680x1050.
Ive tried installing the monitor drivers with no luck.
Does someone has experience on this?
Thanks in advance!

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

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?

Macbook pro and two HP 25xi monitors resolution issues

I have a Macbook Pro with Retina display purchased in 2014. I connected two HP Pavilion 25xi monitors and was having major issues where the second monitor would always be blurry and the resolution would not fit the screen so basically you could not see the border of the screen including the menu bar, sides, etc.
After troubleshooting and looking at blogs, I tried to investigate from the Monitor itself and did the following:
HP Monitor Menu > Image Control > Overscan > Turned it OFF
ISSUE RESOLVED!!!!

Top of the Line?
Meaning which one? I seem to recall reading somewhere it's got something to do with the RAM on the GPU???

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!

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.

External monitor resolution

Hi,
I've just made the longed for switch from pc to mac by buying a 17" mac book pro.
I have also bought a 27" external Viewsonic monitor which arrived today - Christmas come early for me this year.
Everyone's up and running fine, that was easy enough. But I do have an issue with the different resolutions of the 2 monitors.
On the external 27" the screen is not showing all content on the mac book screen - there's areas cropped off top and bottom.
Is there a way to resolve that so I can see the same area as on the mac?
If so how please?
Thanks
ps: External monitor is a Viewsonic VX2753mh-LED 27"
Mac is running OS X 10.6.7

Google this: Screen Spanning Doctor
Note: It may void the warranty, but it does work. Very well in fact.

GE70 2PE secondary monitor resolution issue

So I bought a MSi GE70 2PE yesterday and today I tried connecting it with my tv with HDMI, which has worked fine both with my stationary computer as well as other computers, using the same cable.
Today however when i plugged it into this laptop I got a low 1024 resolution on my tv and the settings for resolution wont allow me to change it to any higher and can't duplicate the screen and extention of screen isn't working properly either as all of my screen apparently can't fit into the 1024 resoltuion, trying to bypass this by changing the resolution while plugging in the HDMI cable the TV just turned black and no sound was transmitted with the HDMI cable.
As far as I can understand for some unknown reason the secondary monitor uses the intel integrated graphics card, I've update the drivers both for this and for the nvidia card.
As for updated drivers, yes all is updated and have tried the general common solutions, the computer was bought yesterday so having a hard time understanding how this can't work properly.
Thanks in advance for any solution.

Actually there is some more questions according to your post:
1. Does the notebook display normally when it's not connected to any external monitor?
2. Where did you change the resolution when you try to bypass the issue? In Intel's graphics properties? or on TV?
3. How did you set the duplicate mode? by using Fn+F2 or WIN+P?

External monitor resolution in Vista on MacBook Pro

I am running Vista Ultimate on a MacBook Pro. I have a Dell 24" external monitor plugged in, which supports a top resolution of 1920 x 1200. But Vista thinks it's a generic non-PnP monitor with a top resolution of 1024 x 768. I have installed the Windows drivers from my Leopard disk, but neither the Vista Displays control panel nor the nVidia software think the resolution of this monitor can go any higher. I tried looking on nVidia's site for newer drivers, but they said for the M series video cards to go to the computer manufacturer for drivers because they modify them for power consumption and other special needs.

I found the solution.

Run setup.exe
You now have full control over your nvidia card. Which also means you can plug in external monitors

Laptop monitor no longer works, and neither does external monitor

My laptop has always had a severe problem with overheating when running even the simplest games, and the fan area in the upper left consistently reaches temperatures unbearable to touch. Using software to find internal temperatures I have found that the CPU usually is about 100 degrees celsius just standing by, and reaches upwards of 130 degrees Celsius when running games. If it ever went much past 130 it would usually shut it self down so it wouldn't fry, but recently the heat seems to have caused the hinge in the area to become ridiculously stiff to the point where the tension cracked the case. This caused the hinge to come out of the casing which placed strain on the cable running through the hinge into the display. I eventually managed to get the hinge back inside the case after it being outside for a few weeks or so, but it didn't seem to matter because a few days later the monitor stopped working completely. It was now just white instead of displaying picture and my first thought was to use an external monitor temporarily but that didn't work either. When booting up the computer the power and fan turn on and the wireless light turns on, first orange then white, and the caps lock key will turn it's light on when pushed. I'm not sure why an external monitor won't work but if anyone can at least help me get that working if not the laptop screen it would be awesome, thanks!

@ckurtz22 ,
I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).

Bootcamp WIndows 7 x64 and Syncmaster 204b external monitor

Hi,
I didn't see a sub-forum for external monitors so I hope the Firmware forum is ok since this seems like a drivers/graphics card issue issue.
The issue I'm having is that Mac OS crashes randomly when I connect my external Samsung Syncmaster 204b monitor to my Macbook Pro when running Windows 7 x64 under Bootcamp. The external monitor turns yellow and the Macbook LCD turns gray and I'm forced to do a hard-reboot. Windows does detect the monitor and I can see it with it's correct name under Windows Display Properties.
Everything works fine when I run the monitor under Mac OS 10.6.4.
I'm running Windows 7 x64 on a mid-2010 Macbook Pro 13". I have all of the latest updates installed for Windows and am using Bootcamp 3.1.
Has anyone encountered a similar issue or have any ideas how this may be resolved?
Thanks, -Scott

Ok, I think this problem has been resolved, so I'll post the solution in case others with the Samsung Syncmaster 204B have the same problem. The answer was erasing the PRAM by holding Option-Command-P-R at boot up (http://support.apple.com/kb/ht1379).
This is what I think happened:
An update in Windows Update is available for the Syncmaster 204B, but wasn't visible when I first connected the Syncmaster. I wasn't able to see the update until I rebooted with the Syncmaster connected (after several crashes). After seeing the update in Windows Update under 'Optional Updates", called "Samsung - Display- 204T/204Ts/204B, Syncmaster Magic CX20Ts(digital)", I installed it, but bootcamp Windows continued to crash randomly after attaching the Syncmaster via both Mini Display Port-to-DVI and Mini Display Port-to-VGA. Sometimes it crashed after a few minutes, sometimes an hour, the same as before I installed the update.
I was convinced that it was a compatibility problem between Windows 7 x64, the Syncmaster 204B and the MacBook Pro 13" Mid-2010 hardware since this problem only happened when booting into bootcamp Windows 7 x64 (everything worked fine in Mac OS), but now that doesn't seem to be the case. I think the update fixed the problem, but after installing the update some of the of the original incompatible display settings remained resident in the Mac's PRAM. Erasing the PRAM cleared these settings and allowed the new updated settings to be loaded instead, fixing the crash issue.

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.

HT3131 Clamshell mode not working even after powering off and reconnecting display; external monitor goes black anyway

After connecting an external monitor (non-Mac) to my MacBook (Mac OSX 10.6.6) w/proper adaptor, setting up to use clamshell mode as per manual, the external still goes black even after putting MacBook to sleep, disconnecting and reconnecting external and powering up again as suggested in Support. Displays are set to Mirror. Also, when I open Displays in System preferences, 2 different windows for Resolution settings appear. Where have I gone wrong? This monitor (Viewsonic) came with it's own software for setup on a Windows PC, but of course it is not being used on the MacBook.
Any help would be appreciated!

Hi Mike,
Yes I followed all the procedueres....except for waking the computer using a keyboard click. For obvious reasons one is just inclined to open the top of the MacBook to wake it when the external goes dark...I did that twice, until I realized that very last step was needed to 'wake' it. It worked. Something so simple, easy to overlook I guess.
I did leave the monitors mirrored, fyi, if I don't then all I can access from the external are the resolution settings. This Viewsonic comes pre-loaded with Windows software of it's own and doesn't quite behanve the way my previous external did, but I got it figured out.
Thanks for your response, tho!
