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.

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

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:

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.
O

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.

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.

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.

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.

Yoga 2 External Display Resolution

I have Yoga 2 and when I conncet it to any external monitor the resolution of the monitor becomes very bad. I'm using the micro to hdmi adaptor. I do not know if there is a better adobtor or if there is some option I need to adjust. Any idea?

Right click on Desktop, click on Screen resolution.
Select the external display and set its resolution. Click Apply

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.

External Display resolution problem after resetting PRAM

Gello, I've got Fujitsu-Siemens P19-2 monitor hooked up to my MbookPro and after resetting PRAM the correct display resolution disappeared from the "Displays" menu in System PReferences.
So did the refresh rate option...
What do I do?
I really need to change the refresh rate and the resolution, but the refresh rate button is grey and unclickable, and the resolution simply isn't there (I need 1280x1024).
REsetting PRAM and SMC didn't help.

After a couple of resets everything went back to normal

External display resolutions - Best connection?

Hi
Wondering if anyone can help shed some light one this subject.
I've hooked up my MacBook Pro Retina to an external monitor. The native resolution of my 30in HP monitor is 2560x1600 (with only DVI inputs), whilst using the MacBook in clamshell mode I'm getting a maximum resolution of 1280x800 and by using the option key, 3 other lower resolution's appear under the scaled radio button. I'm aware there seems to be a problem with Mountain Lion and hooking up external monitors but I'm wondering if my choice of connection may also have something to do with it. I'm using a HDMI to DVI-D cable from MacBook to monitor. Would anyone be able to tell me the maximum resolution this type of cable is able to provide? I'm wondering if its worth buying a mini display port to DVI or another type connection (thunderbolt?) to try and get the monitor to display the maximum resolution. Or would I just be wasting my time and hope that an update will support the monitors resolution?
Thanks for reading!

External Display Resolutions?

I just got a ViewSonic vx2025VM, it's a 20 wide screen LCD. It does not have an option of 1400x900 on it. So what do you do? Can I hurt the graphics card by making the resolution higher on the external monitor, like 1600x1000 or 1680x1050?

no, you can use whatever resolution you want on the external monitor. you can never hurt graphic card by changing resolution.
Also, keep in mind that 30" Cinema display works with our MBP with full resolution (2560 x 1600)
So do not worry about the resolution, set it as you want...

Macbook Pro 13 inch & External Display - resolution problem

Hi
I'm trying to connect my macbook pro 13inch to an NEC 26' Multisync display - which has a native resolution of 1900 x 1200 - and when connected to a PC this is what I get. When I connect the mac though the top resolution is 1900 x 1080 - so the display is distorted.
I've tried finding diplay drivers for the monitor and graphics card without success. Apparently the GEForce 9400 graphics in the macbook can output up to 2500 x 1600.
I'm wondering if it's the connection method - I'm using the mini display to VGA adapter that I got with the macbook. Do I need to use the alternative adapter - the mini display port to DVI adapter? Seems this is needed for connection to 'advanced' displays. Will this make any difference or is it that the macbook 13 inch can't output to a 26in display?
Any advice or assistance will be greatly appreciated
Many Thanks
Tim Gundry

I would get the DVI regardless.
Your taking a digital signal from the macbook, converting to to anolage VGA, and the the monitor is converting it back to digital again to display on the screen.
DVI will make it direct digital to digital.
Plus, because DVI is digital, is passes resolution information. So you should get your native resolution no problem.
