External Samsung 2443BW native resolution not listed

I have a 2007 24" iMac to which I have just added a Samsung Syncmaster 2443BW external monitor on the mini DVI interface. The Mac finds the monitor fine but the preferences panel only shows available resolutions up to 1680 x 1050 at 59.9 Hz rather than the 1920 x 1200 at 60 Hz which is native for the hardware and the same as the iMac panel. I am using the Apple DVI to VGA adapter for hookup and am running this on the analogue input (VGA) to the monitor. I have swapped the VGA cable with a known good one to no effect. Any suggestions fro how to proceed would be welcome. The extended desktop that is desired is usable at the lower resolution but the display is well below it's potential since it is running below native resolution. Thanks for any help offered

Try resetting some of the hardware involved (PRAM~NVRAM). See this Apple KB for details, etc.:

Can't hurt to try, and apparently this has helped others recently.

Why is native resolution not shown HDMI?

Hi,
Just bought a new mac mini, connected to Samsung 932MW via HDMI cable. Can't choose native 1400x900 - not available. Display looks unclear.
Any ideas?
Cheers,
Chris

I just downloaded your model's user manual; it is from 2007 and all the resolutions shown are 4:3; there is no HD or widescreen (16:9). So, the 1440x900 is 4:3 and these are part of my choices in System Prefs (but this is on a 2010 27" iMac:
And yours is a monitor, not a TV - correct?

LCD native resolution not available in system preferences

I need to set my resolution to 1680 x 1050 and that resolution is not vailable. I have a original G4 Mac Mini with Tiger. The monitor has dual inputs for both VGA and DVI, sometimes it will work with the VGA input but not consistantly.
I need to use the DVI input now to leave the VGA input free for my KVM.
I have tried Zapping my PRAM multiple times, starting the Mini with the monitor unplugged, swapping between the DVI and VGA inputs on the LCD monitor, and swapping between my old CT monitor and the new LCD. None of this works.
The LCD always detects as "LCD Display".
I have been unable to find information on where the monitor resolutions are stored, one thing which I would have liked to try would be manually editing the file to the correct resolution.
What else can I try?
Thanks in advance!

Hi Brian, sorry about your issue- it's frustrating isn't it? The file you need to edit is in system > library > frameworks > IOKit.frameworks > Versions > A > Resources, and it's called IOGraphicsProperties.plist. If you activate the root user temporarily using the NetInfo Manager, you can edit the file with textedit, save it to the desktop, then drag it into the Resources folder to replace. When you look in the file, you'll see the following:
<key>gtf-resolutions</key>
<array>
<integer>640</integer>
<integer>800</integer>

I had the same problem as you. I bought an Acer 22" widescreen, with a native resolution of 1680 x 1050, which wasn't "available" in the displays control panel. After some swearing and lamenting the olden days in OS9 when you could just willy nilly see all the resolutions, i added my resolution the this file and it showed up in the control panel. You'll have to monkey with it to see how it works, but basically you're going to add another 'integer' line, like so:
<integer>1680</integer>
If this is too hairy for you, or just too much trouble, i highly recommend SwitchRes. It works perfectly for this problem, and you can input the specifications for your monitor exactly and it will install the resolution so that it's available to the system. Its cheap too.
good luck to you!

BENQ FP241W on Retina Macbook Pro - native resolution not supported?

Hi there,
I have tried connecting my BENQ FP241W monitor to my new Macbook Pro with retina display via HDMI.
The monitor appears to be displaying at only 1600x900 and looks very blurry since the native resolution of the monitor is 1920x1200. I have actually tried this with an older 2009 model macbook pro and the same thing happend, although I was using a dispaly port to HDMI adaptor and never investigated further to the reason the native resolution was not supported.
Going back to the Retina Macbook and the BENQ FP241W. It gives the following resolution options for scaled: 1080p, 1080i and 1600x900. When I choose 1080p or 1080i it looks the same as 1600x900 i.e very blury and not even close to the sharpness that is capable of the display - true 1080p should look sharper than how it looks selected so I dont believe it is actually displaying 1080p. It also has the option for 'best for display' which I would expect it to show native resolution of 1920x1200 - unfortunately it still apears to be 1600x900.
Can anyone help me out? Is this a driver issue or something else?
Thanks
Rich

I can sort this out by just using a HDMI > DVI cable which works fine. I think there must just be an issue with the BenQ HDMI input supporting 1920x1200. Its annoying because the screen is also connected to a PC workstation by DVI so it would be good to have the HDMI for the Macbook so I can quickly switch the display by pressing a button instead of having to unplug cables...

Highest Resolution not listed for 17" LCD

Hi!
I have a hp pavilion f1703 monitor (way to small I know g)and was planning to get a new one next year. But now it seems that I might have to get one rigth now.
Problem is, that the highest Resolution I can choose is 1024 * 768 when it should be 1280 * 1024. Further, the system profiler says that the monitor is a CRT and not a LCD!
I tried getting Drivers from hp. They don't have any for OS X.
I tried using the app DisplayConfigX. Didn't work.
I tried using the app SwitchResX. Didn't work either.
Any ideas?
Macpro Mac OS X (10.4.8)

Problem solved!
All one has to do is reset the PRAM. You can do this pressing and holding the command, apple, p and r keys during startup. Make sure to to this before the screen turns grey!
I also believe to know the reason for the problem.
When I set up my macpro, I plugged in the powercable before anything else. The mac surprised me by immediately starting up. It took me a few minutes to connect the monitor to it. My guess is that the my mac conigured itself before I was able to connect the monitor to it.
Thanks for your effort Stefan!

Equium A100-147 - Native resolution on external LCD doesn't work

Hi,
My Equium A100-147 has 1 VGA and 1 S-Video output, so I'm using the VGA output on a external LCD monitor with native resolution of 1680x1050@60hz, but the integrated Intel 945 graphics card doesnt give me the right resolution to choose for this monitor, the most close is 1600x1200 and some another weird widescreen resolutions that make my monitor scaling show a ugly image.
So I tested another external monitor with native resolution of 1920x1200, and the closest resolution the Intel drivers gave me was 1920x1080, even installing both monitors drivers, removing and reinstalling the driver and even formatting the machine and reinstalling everything from zero didn't give any different results.
I have another laptop MSI Wind with the same graphics card built in and the very same driver version, and the laptop detects both monitor and the right resolutions for them, so it's not a monitor driver problem.
Seems for me that is a problem with the S-Video output that makes this mess, but there is no way to disable it in the BIOS or any another place in device manager I have seem yet.
Does anyone can give me some advice for what can I do?
Thank you!

actually the resolutions available to external monitors here on the intel control panel are
800x600
1024x768
1280x1024
1400x1050
1600x1200
1856x1392
1920x1080
1920x1440
2048x1536
so it seems possible to use another widescreen resolution at least to match aspect ratio without matching the right resolution.
I've just hooked my 1080p hdtv via VGA and I'm able to use 1920x1080 16:9 aspect ratio
seeing this another resolutions that aren't on the manual, maybe its possible to make custom resolutions as well.
I've tried make a custom driver using the intel ones and power strip but without success because I don't know exactly the range of frequencies to setup the driver .inf

Native resolution does not fill entire external display

I've got one of the original MacBook Pros with the Mobility Radeon X1600 hooked up to a Samsung P2350G display (it's a 23" LCD panel.) The native resolution on the display is 1920x1080.
The display has inputs for both VGA and DVI. The DVI port however is used by a desktop PC already, so I use a DVI to VGA adapter on the MacBook Pro, and use the laptop panel as a secondary display.
The problem is that when I set the external display to its native resolution, I get vertical letterboxing and some flickering along the edges of the image. It does not horizontally fill the whole display as it should. I have tried the same adapter on the PC and it worked fine (though with rather spotty image quality.)
Resolutions that are lower than 1920x1080 work fine and fill the whole display properly. I'm not exactly sure what the issue is. The laptop is only semipermanently attached to the large display so I can live with a reduced image quality there, but the flickering, slightly distorted image is just not acceptable right now.

Sounds like it might be a sync issue. Have you tried powering the monitor off and then back on with the MBP connected to it? How about just temporarily disconnecting the DVI cable from the desktop PC and using that to plug into the MBP.

External Display native resolution suddenly not available

Hello,
I'm using a Westinghouse LCM-22w3 external monitor with my MBP, connected via a DVI-to VGA adapter. I've used this computer/monitor setup for quite some time with no problem. Yesterday, I hooked my computer up to my 46" Samsung HDTV with no problem.
When I hooked my computer back up to the Westinghouse, the native resolution (1680x1050) was no longer available. Instead, the monitor hooks up at 1600x1000. Strangely, though, the EDID information appears to suggest that 1680x1050 should be available. Here's the EDID:

Any ideas? Switchresx didn't work, either

Well, you can move the file from the desktop back to its original location to at least get back to what you had before.
The file structure under Snow Leopard has changed and it's hard to keep up with this stuff. There is also now a com.apple.WindowServer.plist file in /System/Library/LaunchDaemons that you could try moving to the desktop and restarting. I dunno. Same rule applies.....if it doesn't help, move the file from the desktop back to its original location.

External monitor will not go to native resolution on my macbook pro

Hi, I have just bought a 22" Westinghouse monitor connected to the dvi and I have no idea on how to display its native resolution of 1680x1050 I have tried mirroring the two monitors and it will not allow me to view the native resolution on my new monitor.
Any help with this is greatly appreciated. Thank you in advance.
Message was edited by: earnerich

earnerich,
When mirroring, your Macbook Pro will default to the highest resolution of the lowest-resolution display. In this case, your external monitor must be driven at your Macbook Pro's highest resolution; 1440 X 900.
If you configure the external monitor as an extended Desktop, you can increase its resolution to its maximum. In extended Desktop mode, both displays can be driven at their highest supported resolution.

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.

Unable to use external display native resolution

Dear all,
Here is the current setup I'm using :
MacbookPro 15", hi res, Mid 2010 with Mac OS 10.6.6, software up-to-date
Apple MiniDisplayPort to VGA Adapter Firmware 1.03
IIYAMA Prolite E2607WSD, a 26" monitor with native resolution of 1920x1200 @ 60Hz
When connecting the MiniDisplayPort to VGA adapter to the VGA cable, the MBP doesn't enable me to set the external native monitor resolution of 1920x1200 with extended desktop. The maximum available resolution the macbookpro is able to diaply is 1920x1080.
What I tried :
-using high performance graphics in the energy saver settings
-using clamshell mode
-using mirroring mode
-reset PRAM
-reset SCM
-delete com.windowserver.plist
-use SwitchResX.app and DisplayConfigX.app to force the native resolution
To make sure that the monitor was correctly behaving, I tried with a PC with WinXP, and I was able to get max resolution of 1920x1200 without an issue. I also tried with a Macbook 2008 with 10.5.6, and with it's own DisplayPort to VGA adapter (the "normal size" one, not the "mini" one I'm using with the MBP), and it worked as well with the native resolution of 1920x1200.
I 'm coming to the conclusion that either the minidisplayport to vga adapter doesn't accept any resolution higher than 1920x1080 or that the one I bought from Apple is not properly working, or that I should use the minidisplay port to DVI adapter (no HDMI here as an input for the monitor)...
I also browsed the forum and found a lot of similar issues, so I guess it's pretty common, but no workaround seems possible.
Does anybody in the community had the same issue and know how to solve it ?
Thanks in advance.

Hello BSteely,
I actually tried to get the EDID information and to replicate them as much as possible but everytime I tried a custom resolution, after reboot, SRX will say " the system didn't accept this setup"... and the proper resolution is not available..

Portege Z30-A-18M - cannot set native resolution on external display

Hi,
I have tried to connect two different full HD displays to my Portege Z30-A-18M and I was unable to set the native resolution - maximal resolution that I can set for those is 1680x1050... I wasn't so surprised with the first one as I had some troubles with native resolution when I was connecting it to the Satellite laptop that I had before. But then the same happened when I tried the other display.
I thought that this laptop can handle higher external resolution... Is there a way how to force the native resolution for the external diplays in Windows 7?
Thanks!

Well, I wanted to use it as extended desktop... But I tried now to set it only to external device and I am still getting 1680x1050 as max
Just a note, the first display was connected with analog (D-SUB) and the second with digital (HDMI) ...
Is there a way how to override the maximum and set my own custom resolution?

What external drives work well with a late 2011 MacBook Pro? I ask because I just found out the hard way that a Samsung EVO 840 does not. Also should I avail myself of something that works with Thunderbolt or Firewire?

What external drives work well with a late 2011 MacBook Pro (I7, Lion OS) apart from my Kingston flash and USB drive, and the SD drives that I use in my cameras and recording devices? I ask because I just found out the hard way that a Samsung EVO 840 does not. Also, should I avail myself of something that works with the Thunderbolt or Firewire connections? I'm looking to back up music and video files created and/or processed in Logic Pro and the Adobe Production Premium software suite (Premier Pro, After Effects, Audition, etc).

Hmm, not sure what problems you had installing this drive. The review here gives it good marks for Mac:
http://www.amazon.com/Samsung-Electronics-EVO-Series-2-5-Inch-MZ-7TE1T0BW/produc t-reviews/B00E3W16OU
There does seem to be a lot of prep to make it work:
"1. Preparation to install your new shiny SSD
1.a You will need a migration tool (I used the Sabrent kit USB 3.0 to Sata that was suggested in these review) see link http://www.amazon.com/gp/product/B00DQJME7Y/ref=oh_details_o03_s01_i01?ie=UTF8&p sc=1
1.b You will need to download a trim enabler (mid 2012 macbooks only support native trim with apple brand ssd's) I recommend going to cindori.org and downloading trim enabler version 3.xx. You can do this step before or after the OS migration
1.c You cannot use the Samsung SSD migration software *don't worry Mac has its own imaging/migration utility*"
Also in those reviews:
" Only down side when using this product in a Mac Mini is you will be required to download and install Trim Enabler so that your drive performs optimally on your Mac device. This is an Apple issue, not Samsung, but it is an extra step you will have to take after you install the hard drive, and any time you perform an OS upgrade." He rant's on.
Personally I only deal with OWC:
http://eshop.macsales.com/shop/SSD/OWC/
They are very knowledgable and if there's a problem they will gladly take back the item. (Never happened to me yet - 8 years and counting).
Just upgraded my 13" MBP 2011 to 120 GB for $79. Adobe CS 6 opens in 3 seconds! Awesome!
When I was in Chicago I had a pro photographer for a client. She wound up with 4 internal drives in her Pro, 4 external drives and an dual array locked in a steel vault in the basement. All from OWC. OK she was a bit paranoid. Great client though.
As far as value for price:
http://eshop.macsales.com/item/OWC/MES3FH7500G/
500 GB for $130.
However as far as reliability is concerned:

http://www.extremetech.com/computing/173887-ssd-stress-testing-finds-intel-might -be-the-only-reliable-drive-manufacturer
So sudden power loss is an issue with SSDs.
Personally I'd go with a moderate sized SSD internally and a conventional external for backup. An array would be the most reliable.

System preference SOUND does not list Samsung as a choice. Picture is perfect, but no sound.

My Samsung shows up in the display settings, but not in the sound settings. It's not listed. Does Mac have an "add hardware" function? System Preferences is reading the Samsung DISPLAY, but not the SOUND list does not include Samsung. What middle step am I missing? I'm sure there must be some way to get the Samsung sound recognized.

I have Thunderbolt as well, and I get a great picture. I just don't get any sound. i read a suggestion in this group to go to System Preferences>Sound>Output>and choose Samsung, but Samsung isn't a choice. This is why I raised the question of how to add Samsung to the list. I'm using my TV as a mirror. Could that be the problem? How do you use your HDTV?
