External Display Resolution Issue...

I have a Mid-2012 MPB running Mavericks. Recently, I've tried connecting 2 different external display's to the MBP via an Apple Thunderbolt to VGA adaptor. I can't get the resolution of the connected displays to go above 800 x 600, and it looks awful.
The first screen is a Samsung SyncMaster T260HD with a native res of 1920 x 1200, and the other is a Samsung SyncMaster 933HD, with a native res of 1366 x 768. I plug them into my Windows box via a VGA cable, and it will drive each display at it's native res just fine. So what have I missed to get the MBP to do this???
Thanks in advance. :-)

My MBP has Thunderbolt and I have a mini displayport to DVI adapter. This is connected to the DVI port in the display.
That option key selection did not increase the alternative resolutions available.
I did reset PRAM according to a advise hee in the community. That did not help either.

External display resolution changes after returning from display sleep

I often use an external display as a second screen with my Macbook Pro (OS X 10.8.2) However, when I return to the computer after the display has gone to sleep, the external display resolution changes when the display reappears. Then I have to go into System Preferences > Display and "Detect Displays" in order to return the external display to the proper resolution.
Does anybody know of a way for me to avoid having to do this every time my display sleeps?
Thank you,
Adam

I have the exact same problem.
I found the key combination ⌘ alt F2 also restores the proper resolution on both displays, however it's still a bit annoying

Conflicting information about external display resolution - please help!

I have a MacBook Pro (15-inch, Mid 2009) with the non-reflective screen, Mini Display Port and NVIDIA GeForce 9400M Graphics processor.
According to these technical specifications (http://support.apple.com/kb/SP544), the built-in NVIDIA GeForce 9400M Graphics processor supports full native resolution on the built-in display and up to 2560 by 1600 pixels on an external display.
Armed with this information, I just purchased a shiny, new DELL U2711 (http://accessories.us.dell.com/sna/productdetail.aspx?c=us&cs=04&l=en&s=bsd&sku= 224-8284&redirect=1) external display which has a resolution of 2560 x 1440. Unfortunately, all I can get out of it is 1920 x 1080 (This is the maximum resolution I can select in the monitors system preferences panel.)
So Apple tells me this graphics card supports 2560 x 1600, but I also contacted NVIDIA directly who told me that this particular card's maximum resolution is 1920 x 1080.
Somebody has to be wrong. Is this monitor supported? Am I doing something wrong? Do I need to send this monitor back and buy a smaller display?
Any advice would be greatly appreciated.

Well - seeing as nobody could provide any help on this, I'll post the answer in case anybody else has the same problem.
It turns out that the monitor's resolution IS supported by the NVIDIA GeForce 9400M, so the information NVIDIA gave me was wrong.
The issue was the adaptor.
A regular Mini Display > DVI adaptor can only handle a resolution of 1920 x 1080. Turns out I needed a Mini Display > DUAL LINK DVI Adapter, which is a combination of USB and DVI which provides the required resolution of 2560 x 1600.

External display resolution

I have Dell up2414q monitor which is capable of displaying up to 3840 x 2160. But when I connect my 11-inch Macbook Air (the latest 2014 model), which is capable of 2560 x 1600, shows only 1920 x 1080. This is the highest resolution listed in display setting.
I'm using Display Port cable and enabled Display Port 1.2 setting on the monitor. I went to Apple Store and asked, but they had no idea what was wrong. My OS is 10.9.3.

My T500 external display colour issue

Hello all,
Before I invoke my warranty on my laptop I thought I would try here first. My external display all of a sudden today, started to turn yellow. It seems like its random as to what exactly is being turned yellow, but it seems like almost every part of the screen is effected. Some facts:
1. I have tried 2 different monitors and 3 different VGA cables with the exact same results.
2. When I first plugged the monitor in today and set it to output only to monitor, the screen was fine, when I changed it to 1680x1050, the yellow instantly showed up
3. Whatever resolution I try now, its always the same
4. I have rebooted, tried extended, clone and one screen displays, I have even tried rotating the display!
So thats the story, my gut feeling says the video card in the laptop is the issue, but I do not know enough about it to be sure.
Anything anybody can think of that I can try before calling it in?
Cheers,
Darren

Does it work if you plug it into a different source? What if you plug the cable directly into the T500's onboard DisplayPort?

How to change external display resolution WITHOUT clicking "CONFIRM"?

I have a somewhat unusual situation. My MacBook laptop is actually now a ModBook (a pen-tablet computer), and as such I no longer have a trackpad attached to it. All of my inputs are via the stylus, tapping directly on the built-in display.
This works perfectly fine, except when I need to give presentations on an LCD projector (which is quite often lately). I like to use the projector as an external monitor, so that I can run the Keynote presentation on it while using my laptop screen as the presenter's display, with the upcoming slide, etc. If the projector doesn't give me an ideal native display option (sometimes, the aspect ratio for the 3 or 4 resolutions available in the Displays drop-down in the menubar turn out to be stretched or squeezed), then I, naturally, have to open the Display System Preferences and try out different resolutions.
The problem is, since my stylus only interacts by clicking directly on the built-in-display, I have no way of moving the cursor over to the external display when the dialog box with the "Click here to confirm change/You have 15 seconds..." message appears. So I can never click it ... so I can never confirm the new settings.
The workarounds I've used so far are:
- Mirror displays (not ideal, as I need the presenter preview of the next slide)
- borrow a mouse from someone (usually from a Windows desktop, frankly) and plug that in to briefly mouse over and click the confirm button
I'd love to find a software workaround that allows me to NOT mirror displays and also doesn't require me to carry around a mouse all the time (my laptop bag is already overstuffed...).
Thanks.

Thinkpad Yoga - Insufficient external display resolution over the Onelink

My local Lenovo Partner just confirmed the data in "User Guide" of the TPYoga, that the external screen resolution will only be 1920x1200.
"User Guide" Page 10, http://www.lenovo.com/shop/americas/content/user_guides/tpyoga_ug_en.pdf
"Display resolution:
– LCD: 1366-by-768 or 1920-by-1080, depending on the model
– External monitor: up to 1920-by-1200, depending on the monitor model"
I mean what do I want the OneLink Dock / OneLink PRO Dock for??
Of cause to connect a large screen and this not with a worse ppi than the intern display. So I need at least 2560x1600
(we don’t even talk about all the disadvantages of a 16:9 screen, cause that’s off topic).
Idealy I expect of cause a 4k resolution possibility together with the OneLink Pro Dock and multi stream (daisy chain) possibility at the display port.
But 1920x1200 external graphic output can’t be meant serious for a 2000US$ device??

Ok, let’s accept that the new Thinkpad YOGA Manual includes misinformation.
Actually I’m sitting in front of my 2048x1152 Display which is connected to my 8 years old Asus Notebook via DVI. Does this old jalopy perform a higher resolution via DVI than the Thinkpad Yoga via “OneLink PRO Dock-DVI” does?
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/options/tp_onelink_pro_dock_ug_en.pdf
Page 13
(I’m guessing in the first line (behind "One monitor") it’s supposed to mean DVI instead of DP”
(1) Lenovo, are these technical details of the NEW OneLink Pro Dock also wrong like the Manual of the Yoga regarding the maximum resolution?
Would be very helpful for me to plan with correct information..
(2) And is it definitely true that I can't connect two displays at the OneLink PRO Dock with a higher resolution than 1920x1200??
That would mean I send the Thinkpad Yoga back and better stay with my 8 years old ASUS jalopy.. smileyfrustrated:

Leopard "Forgets" External Display Resolution

I have a 17" MacBook Pro C2D (Oct 2006 revision) that I use at work with an external display (Dell E197FP) that is connected to the laptop via the DVI-to-VGA adaptor. The Dell has a native display resolution of 1280*1024 @60Hz and this is set via the System Preference's Display panel. The problem is that quite often when I connect the display in the morning OS X (10.5.6, at present) "forgets" the resolution that has been set and reverts back to its default for the display, which is 1152*864 @75Hz. It is baffling to me that it keeps forgetting the selected resolution for the display, despite recognising it, and that it selects such an odd resolution as a default. This happens about once per week at the moment.
Does anyone have an idea what is causing this and how I can stop OS X from being so forgetful?

Are you getting one to extend your desktop? I don't, I use my MacBook with the screen off using my external only with a keyboard and mouse plugged in. I run my Late 2008 2.1GHz MacBook with a GMA X3100 using a 23" Samsung wide ratio no problem in 1680x1050. It is high resolution. Make sure you click "mirror" in Display Prefs. Be certain that you don't simply boot to both because the external will appear grainy and only be putting out the native 1280 X 800 13" MacBook resolution on the new big LCD. There are many different ways to achieve this. With the LCD on and hooked to the MacBook, turn the MacBook on then quickly close lid after the chime. Give it some time. After it boots to the external, I open the lid to provide proper airflow, some may argue it's not needed.

Macbook Pro, how to reset invalid external display resolution?

Hi there. I have a question about the external display configuration.
I recently connected my 2011 Macbook Pro 13" (10.8.2 Mountain Lion) to an external HD-TV using Thunderbolt to VGA adapter. After connecting the TV had 1920x1200 resolution which made the text and everything look very tiny. So I thought I'd lower the resolution a bit. But then I messed up and accidentally changed the resolution and refresh rate for the external display to one that wasn't supported. So the TV went black and gave an error about an invalid resolution. At the same time, on my Macbook screen I had only the background image and display settings dialog. No mouse cursor, no menu bar, no dock etc. So I couldn't do anything.
I disconnected the Thunderbolt adapter and got my Macbook screen back to normal, but when I plugged it in again, the same thing happened. Invalid resolution on TV, just background image and display settings on Macbook screen.
Now, this was just before I was going to give a presentation and it resulted in a very awkward situation with me franticly re-plugging the Thunderbolt adapter and looking just completely clueless In the end I had to borrow my colleague's laptop.
So my question is: when this happens, is there a way I can reset / clear the external display settings back to defaults? They are obviously saved somewhere since replugging the Thunderbolt adapter didn't give me back my original resolution.

A PRAM reset should solve that:
From the article linked above:
Your Mac stores certain settings in a special memory area even if it is turned off. On Intel-based Macs, this is stored in memory known as NVRAM; on PowerPC-based Macs, this is stored in memory known as PRAM.
Information stored in NVRAM / PRAM includes:
Speaker volume
Screen resolution
Startup disk selection
Recent kernel panic information, if any
To reset your PRAM:
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

OS X 10.8.3 Display Resolution Issue

Ever since updating to 10.8.3, there has been a sporatic resolution issue when waking my MBP. My mid 2009 13" MBP operates in closed lid mode while connected to a 21.5" monitor. My machine frequently wakes to a completely incorrect resolution that is many times the size of my display. It fixes to the correct resolution if I simply sleep and wake again, or correct it via System Preferences, but having to do this several times becomes quite annoying. Anyone else experiencing this bug and/or have any ideas on its resolution?

Hi GoldenA,
Thanks for visiting Apple Support Communities.
It may help to reset the NVRAM by following the steps in this article:

Internal vs. External Display Resolution

Hi,
I just purchased a KVM switch by IO Gear Model GCS1782. Hooked up my Mac Book Pro 15 inch 2.16 Ghz with DVI Dual Link and Mac Mini Power PC with DVI single link.
The KVM is working perfectly. The Mac Mini Display resolution is 1680x1050 as normal. The MBP Color LCD is 1440x900 as normal.
Question: Why does the display on the internal display of the MBP look crisper than the Cinema Display? The CD looks like a lo res VGA monitor.

Okay everybody...something funny happened this morning.
Last night I put my MBP to sleep by using "Insomnia" and woke it up this morning and to my surprise, the resolution is matched. No more fuzziness. I have the display icon on the title bar which shows the only one display, only the ACD at 1680x1050. Yesterday it showed two displays because I was mirroring.
Yesterday morning I hooked up a new KVM (I/O Gear Model GCS1782) and discovered video display problems (not from the KVM). From 10:30 AM to 2:45 PM I called IO Gear support, Apple Sale Support (x2), Apple Technical Support (x2), and continuously scoured these forum reading and posting.
Yesterday:
1. Could not close lid of MBP because ACD would go black. (Solution: Insomnia)
2. Could not get MBP LCD display be crisp on the external ACD (Solution: Insomnia)
3. Mirrored the MBP causing the ACD to use a lower resolution (Solution: Insomnia)
Today, all is well.
I think it had to do with the MBP sleep mode or ????. I am not positive on what exactly happened to get the max resolution. I am just a wee bit concerned that it will happen again because I have to disconnect the MBP tomorrow and reconnect without the confidence I can get it to work. One thing for sure, I won't mirror any longer.
Lessons Learned:
1. No one person is proficient with using external displays on MBP. The pieces of information that I needed were either scattered and fragmented or just not available.
2. The people at Apple is nice, helpful, and well meaning. But this particular situation revealed a lack of technical cohesion in its communication.
I want to thank all the good people who help me along this journey.

R200 - Question about external display resolution 1920*1200

My boss has bought this screen and is a little bit disappointed because he can't reach the maximum resolution of the 23" tft screen 1920*1200. The R200 proposes only resolution that have an aspect ratio of 4:3 so the maximum for the screen is 1600*1200. Is there a "special" driver for the graphic chip that allow non 4:3 resolution ?
Thanks

Hello
As far as I know on external display the maximum resolution is restriction of the graphic card and unfortunately there is nothing to do. The only thing that you can do is to check all settings in TFT menu. I am pretty sure that there you will find an option for picture format switching.

No Wireless Internet with External Display, Other Issues

Hello,
When I connect an external monitor to my MBA, I lose my connection to the Internet. The wi-fi signal remains strong, but pages will not load (I tried many) and I cannot retrieve email. The connection times out when I try to ping as well. This occurs whether I have the MBA open or closed. The loss of Internet happens immediately when I connect an external display using the supplied dongle, and returns the moment I disconnect it. It is clearly an issue with external displays.
On the advice of an Apple Genius, I also tried disabling bluetooth. I did so, and turned off all my bluetooth devices (Apple keyboard and mouse, iPhone), but the problems persist.
The other trouble I am having is difficulty connecting to a network for the first time in a session. In other words, I was connected all day yesterday, take the MBA home, and return to the office the next day. MBA takes a long time to see the network, then fails to accept the password. If I carry the MBA closer to the wireless router, it finds and connects automatically as I'd saved my password. When I return to my desk, I remain connected with full signal strength. This has happened in two locations, one with an Airport Extreme, the other with a Netopia 802.11g router. When my Macbook Pro is sitting right next to the MBA, it recognizes and connects to the same networks almost instantaneously.
Anyone have any suggestions? Much appreciated.

Just a quick update... I was on the phone with Apple Support on Saturday morning and I thought we were making progress. The basic idea behind the proposed solution was that there was some "Preferences" that were causing the problem. We started over with a clean Preferences folder and tried connecting up the external monitor. At first, this approach was showing progress. The suggestion was to copy over my original Preferences (I had made a backup copy) just a few at a time until we figured out which ones caused the problem. The problem with this approach is that immediately after I got off the phone, the internet started not to work again. So, even with a clean Preferences folder, the internet would quit working after connecting up the external monitor.
So, I'm back to the drawing board. I have since restored my Preferences folder and I don't have my external monitor and internet working at the same time. BTW, I also upgraded to 10.5.3 and it didn't help.
Still bummed,
Kevin

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".

Stefan
