Native resolution of external monitor not appearing in System Prefs - Displays

I have an Acer G206HL monitor, which has a 1600x900 native resolution. It's connected to a 13" MacBook Pro (the current non-retina model) via a Thunderbolt-to-VGA cable. The MBP is running Mountain Lion 10.8.3.
When I go to System Preferences -> Displays -> Resolution: Scaled, 1600x900 doesn't appear in the list, and none of the listed resolutions are satisfactory.
Anyone know of a way to add custom resolutions to Mountain Lion's Display preferences?

I'm having the same issue with a a 2012 MBA running Yosemite 10.10.1 (14B25). I wish I could find a solution to this problem.

MacBook Pro (2011) won't display 2560x1440 native resolution on external monitor

I have the new MacBook Pro 15inch with 2.2Ghz quad core and an external NEC PA271W Monitor with a 2560x1440 native resoultion. I have them plugged together via the dual-link DVI-D cable but the MacBook pro will only recognize 1920x1080 as the max resolution on the NEC monitor. How can I output the max 2560x1440 resolution to the monitor?
The MacBook Pro is left open for dual screen view. Please help. Thanks!

I am surprised no one asked you the following question regarding your response.
What if I don't what 2 displays and I only want to support the external monitor? Can I be in extended mode and have only 1 display?
The reason why I ask is because I am going to buy a dock for my MacBook (2012). The dock forces the MacBook to close thereby rendering the internal display useless.
I think what I am after is some sort of "extended to external" mode.

Apple Desktop pictures do not appear in System Prefs

I tried to change my desktop picture and discovered that there are none of the apple images showing in the system prefs for Desktop & Screen Saver. The folders are there (Apple images, nature, plants, etc) but the folders are empty.
Digging via the finder I found in Library/Desktop Pictures all of the missing files but Prefs does not apparently see them.
The default Aurora was there after 10.5.5 upgrade, then I replaced it with one of my own from the user/Pictures folder which shows in the prefs window. All of those pictures still show in prefs.
What is wrong?

Conclusion, there is now something about my account that no longer can see the contents of the Desktop Pictures folder. Why is unknown still.
Usually, a bad preference file or incompatible login item is the culprit, although it could also be corrupted data in a user cache.
For the first, you can try moving likely suspects from ~/Library/Preferences to a desktop temp folder, then logging out & back in or restarting to see if the problem is gone. If not replace the old preference from the temp folder to its original location to restore the old preferences. One general way that may help locate suspect pref files is to change the preference in the normal way while ~/Library/Preferences is sorted by date changed -- the file storing the preferences should be very near the top of the list.
You can also run a terminal command that checks the syntax of most preference files. It won't indicate all problems but it is worth a shot. In Terminal type:
sudo plutil -s ~/Library/preferences/*.plist
followed by pressing the return key. At the password prompt, enter you admin account password & press return again. It won't be echoed to the screen. If you get nothing besides the prompt for the next command, those prefs are syntactically correct. Otherwise, remove the indicated pref file as above & test.
If desired, repeat this for the main system-wide preference folder with this command:
sudo plutil -s /Library/preferences/*.plist
Note: since your new account has no problems, it is highly unlikely a system preference is the problem.
For login items, check the list in the accounts system preference. Suspect anything that isn't from Apple. You can list them here in a new post if you have any questions about them.
If the problem is a bad user cache, a third party utility like Onyx or Leopard Cache Cleaner will allow you to "clean" (delete) them. Try this as a last resort, since caches speed up the operation of your Mac & will need to be rebuild by the system, causing one-time delays until this is done.

Setting resolution on External Monitor

I have a Macbook Pro (from 2008) and a 25.5" Samsung T260HD which has a native resolution of 1920x1200.
I need to mirror the displays or at least have all icons and such on the external display. When I mirror them, I cannot get the external monitor to use it's native resolution. instead it uses a lesser setting.
Only when I have them set to display side by side does it use 1920x1200, but then I have to go back and forth which doesn't work for my purposes.
Thanks for advice!

when you do a mirror, you are asking for a 1:1 replication of your laptop screen. so, it's not feasable to have 2 different resolutions in mirror mode. it will only do whatever your laptop is set to.
the only MBP that will push 1920x1200 in mirror mode is a 17" HD or unibody 17". you will have to run in clamshell mode or in extended desktop to utilized the native res of the display.

Help with Resolution on External Monitor

I want to set my HP Envy 15t to drive an external monitor, not as an extension, but rather as my primary monitor. My external monitor is a Viewsonic VX2250, a little older, and requires that I use a HDMI-to-VGA adapter. (The Viewsonic also has DVI inputs...not sure it that would make a difference.) On my current tower setup, I use the monitor in its recommended (or native mode) setting of 1920x1080. I like this screen a lot.
The adapter is a Bytecc HM-VGA005 and the specs seem to suggest that it can handle a variety of video resolutions - Full HD (1080p), WUXGA (1920x1200 RB mode), and UXGA (1600x1200 VESA mode).
The 15t currently runs in the recommended resolution of 1366x768. If I understand the specs right, in HD mode it's 1366x768 and in FHD mode it's 1920x1080. The graphics card is an Intel HD Graphics 4600. Is this the reason that I can only get HD resolution and not FHD resolution on the laptop?
But whenever I plug all this together and try and change the laptop screen resolution settings, the external monitor only shows 1024x768...pretty lousy. I have it so that the laptop screen is dark and only the external monitor is on. But there doesn't seem to be any choices I can make to improve this resolution. I've checked to see that the graphics driver is up to date and it is.
What do I do to get the best screen I can on the external monitor? Would buying a new monitor with HDMI inputs achieve better results? Do I need a different adapter?
Thanks...Kurt
This question was solved.
View Solution.

Me again! Well, it was a bit of the nut behind the wheel. I checked in with the store that I've been buying my cables, adapters, etc. He said to bring the Viewsonic monitor by to see what might be going on. As I was setting up, he asked about power to the adapter. I had the USB cable but didn't think it was needed. But after putting everything together in addition to power to the HDMI-VGA adapter, I could see I was getting the resolution that I was hoping for. Why it worked on the Dell monitor, no clue...maybe a better monitor or different VGA cable. The Bytecc adpater didn't come with any instructions, so I just didn't know.
All is well. Hope this helps someone in the future.

T400s max resolution for external monitor ?

Hello
What is the max resolution for an external monitor connected to a thinkpad t400s ? The reason i am asking is that:
a) Intel says: the max resolution of Graphics Media Accelerator 4500MHD is 2048x1536
b) Lenovo says: DisplayPort + D-sub dual-display output support 2560×1600 maximum resolution
What are your experiences and what maximum resolutions on external monitors have you succesfuly tried in real life ?
Would it be possible to connect a 30" monitor at 2560x1600 to a thinkpad t400s ?

i don't know and i never tried but i'm inclined to trust intel more than lenovo on this...unless the t400s has some beefed-up x4500mhd
T400s - 2815RW1 + Win7 Ultimate
Don't pm me for help! That's what the forum is for. Also, Google's nicer than me. Ask him.

No video to second external monitor but recognized by system

When I connect two external monitors(22 inch AOC) using mini display adapters to VGA or USB to VGA adapter from my MacBook Pro (Retina, 15-inch, Late 2013) with an Intel Iris Pro 1536 MB graphics driver and recently updated to OS X Yosemite Ver 10.10, I only have one of the external monitors showing a picture, the other is a black screen. When going to 'Displays' through settings both external monitors are recognized and shown. I can arrange them how I want. When going into 'About this Mac' and selecting 'Displays' both monitors are displayed as active. No matter which port I use and no matter which monitor I switch around it is always the same. One monitor dark and the other working but both always recognized by the system. Any ideas for me? Thanks

Hello iorjim,
Thanks for using Apple Support Communities.
To troubleshoot this issue where you are not seeing a signal on your secondary display, I'd like you to please follow the steps in the article below in the "No video or no signal" section.

Instant Client on 64-bit Windows 7: Driver does not appear in System DSN

Instant Client on 64-bit Windows 7: Driver does not appear in System DSN tab when creating a new Data source.
What I did so far:
I downloaded the basic and odbc zips for Window 64-bit.
Unzipped the basic zip.
Unzipped the odbc zip to the same directory.
Added the dir path to the System Environment Variable called Path.
Double-clicked on the odbc_install.exe to run it from Windows Explorer.
Then I tried to add the driver to create a new data source but it does not appear in the list of drivers.
From a cmd window, I navigated to the instant client directory and tried to run odbc_install again.
I got the message: Oracle ODBC Driver with same name already exists.
What am I missing?

hello, I did it like that you say,but the result also is "oracle odbc driver with same name already exists". I don't kown what can I do it ,Thank you!

Please always post your operating system when you have a question since in many cases the answer depends on it.
Lioin 10.7.2 is required for iCloud - if you have anything earlier you can't use it directly.
You will be able to access email, calendar and contacts on the iCloud website at http://icloud.com provided your browser is reasonably up-to-date.
You will not be able to sync contacts or bookmarks from a pre-Lion Mac.
You will be able to enter the server settings for email manually in the Mail application and access your email.
You will not be able to sync your calendars directly.
Some people have been able to set up calendar syncing by using the method detailed here - this is an unsupported hack and may not be reliable, and may stop working at some future point. BusyCal is an iCal-like calendar application with extra facilities: it can sync with the iCloud Calendar while running on Leopard, Snow Leopard or Lion.
There appears to be no method of syncing contacts (though Address Book on a Mac can be synced with Google or Yahoo address books - I don't know how reliable this is).

How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.

How can i use my smart TV as a second monitor for my Power mac (2010) via HDMI cable? i've made the connection but no options show in system prefs display.

the TV: LG Smart tv

The Mac uses a highly-parameterized universal Driver for every display. The parameters are set at certain times when a query is sent to your display. The display MUST answer with its name and capabilities, or the screen stays dark. A TV set that is off or "not paying attention" because it is set to a different port when the query occurs will rarely answer, and so will often remain dark.
You can use tools in the System Report to see whether your display has been detected at all. If it has, the report will look something like this, but its name will appear:
The times when the query is sent are:
• at Startup
• at wake from sleep
• when the Mac-end of the cable is inserted
• when using the Option ( Detect Displays ) button in displays preferences

You may have installed one or more of the common types of ad-injection malware. Follow the instructions on this Apple Support page to remove it. It's been reported that some variants of the "VSearch" malware block access to the page. If that happens, start in safe mode by holding down the shift key at the startup chime, then try again.
Back up all data before making any changes.
One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those. If Safari crashes on launch, skip that step and come back to it after you've done everything else.
If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, ask for further instructions.
Make sure you don't repeat the mistake that led you to install the malware. It may have come from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
Malware is also found on websites that traffic in pirated content such as video. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Still in System Preferences, open the App Store or Software Update pane and check the box marked
Install system data files and security updates (OS X 10.10 or later)
or
Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

"Avast" is the worst of the whole wretched lot of commercial "security" products for the Mac. Not only does it fail to protect you from any real danger, it may send personal data (such as web browsing history and the contents of email messages) back to the developer without your knowledge, give false warnings, destabilize and slow down the computer, expose you to network attack, and corrupt the network settings and the permissions of files in your home folder. Removing it may not repair all the damage.
Some versions of the product also inject advertising into web pages. In short, apart from the fine print in the license agreement, Avast is indistinguishable from malware, and is arguably worse than any known malware now in circulation.
Back up all data, then remove Avast according to the developer's instructions. Restart.
If you tried to remove Avast by dragging an application to the Trash, you'll have to reinstall it and then follow the instructions linked above.

External Monitor not displaying correct resolution.

I just hooked up my Viewsonic 19" widescreen display (1440x900) to my MacBook Pro. Ive closed the lid of my laptop and set the resolution to 1440x900 (60hz) in System Preferences yet the external display is still fuzzy. I looked in the monitors menus and it says its currently displaying 1152x864!!!!
When i tried mirror mode it looks like it thinks the external monitor is a different size but both screens have the same native resolution.
I've tried a bunch of different resolutions but none of them seem to use my monitors native resolution. I'm using the included DVI to VGA adaptor into the monitor. The monitor works fine if I plug it into my old Dell XP Laptop or XP desktop.
Does anyone have any suggestions?

Same "fuzzy" picture on external LCD attached to MacBook Pro here (2GHz, 2GB RAM, 10.4.11). Been using a mediocre NEC LCD72vx for along time and figured that was the reason, but I tried a stellar ViewSonic VG191b that I use with my Windows desktop for layout and found the same slightly fuzzy picture, despite also noting that the resolution setting was the native one. Note, I use the external display rotated 90, but I saw no change at 0 rotation. Straight DVI on both.
Half of the fun of having DVI out is its usefulness for layout in publishing. Powerful MBP, poor external display quality. I think some sort of fix is indicated here.
