MacBook Pro :: Unable To Get Native 2560 Resolution On External Monitor
Jun 27, 2014
I have a Samsung SB970 S27B970D 27-Inch Screen LED-Lit Monitor with native resolution of 2560x1440. When I connect it to my 2012 13" MacBook Pro via mini display port to DVI, I am unable to get anything better than 1080p.
Here's what System Information shows for my displays. Intel HD Graphics 4000: Chipset Model: Intel HD Graphics 4000 Type: GPU Bus: Built-In VRAM (Total): 768 MB Vendor: Intel (0x8086) Device ID: 0x0166 Revision ID: 0x0009 Displays:Color LCD: Display Type: LCD Resolution: 2560 X 1600 Retina: Yes Pixel Depth: 32-Bit Color (ARGB8888) Mirror: On Mirror Status: Hardware Mirror Online: Yes Built-In: Yes Connection Type: DisplayPortS27B970: Resolution: 1920 x 1080 @ 60 Hz Pixel Depth: 32-Bit Color (ARGB8888) Display Serial Number: H3HCA00500 Main Display: Yes Mirror: On Mirror Status: Master Mirror Online: Yes Rotation: Supported Television: Yes
As you can see, 2560 should be supported.
Also note that we have two different MBPs and two different Samsung monitors (same model, ordered at different times) that do the same thing.

Here are my hardware specs:
Mac Pro 1,1
NVidia 7300GT (I need a new video card, anyone want to sell me one? [=)
2 x Samsung Synmaster 2494SW (native resolution 1920x1080)
Update:
I booted into windows 7 and I am now able to get both native resolutions.
Though, I am still unable to get both native resolutions (using DVI to DVIs) inside OS X for some reason. In OS X my second monitor is displayed as "VGA Display" and it completely black.
I am not sure why it works in bootcamp using Windows 7, but not in Snow Leopard. I am guessing this is a problem with the OS X configuration.

I have a Hyundai W240D 24" LCD monitor and it works perfectly in Windows Vista SP2 64 bit running under Boot Camp but when I restart the computer to use Mac OS X it only shows 1920 x 1080 as the maximum resolution rather than 1920 x 1200. I have zapped the PRAM, repaired disk permissions and run fsck -f in single user mode and still the problem persists. Does anyone have any suggestions for how to fix this?

I use an external monitor from Dell with my Macbook Pro 13.3". For some reason I am not allowed to set this monitor at highest possible resolution? Or perhaps that's the best for this monitor which admittedly is quite old. But when I go into my system preferences it shows option for higher resolutions but doesn't allow me to select one.

MacBook Pro, Mac OS X (10.6.8)

I have a 24" external display and since 10.5.7 I cannot use it with the native resolution (1920x1200), the maximum I can pick is 1920x1080.

Just bought a new 22' LG monitor and I have the Mini DisplayPort to VGA. When I connect my monitor to my MacBook all is OK until I try to chose the 1680x1050 which is the LG's prefered resolution. When I chose it, my monitor turns to black, then after a while it shows the picture for a second, then black again.. Is this a 9400m fault, or the VGA adapter fault?If I try a MiniDisplay port to DVI, will it work in 1680 x 1050?
All the other resolutions are shown ok..

I just found out that if I use the "mirroring" mode, and I set the resolution to 1680x1050 and 60hz(my monitor max resolution/hz), it's all kinda blurry... But if I put in sleep mode ma MPB and wake it up "switching on" my bluetooth keyboard, the monitor in my MBP doesn't even start and it just use the external monitor. In this case, there's no more blurriness but the settings are the same! Then, I can even turn on my MBP monitor (pressing some random key on its keyboard) and nothing change, still no blurriness...
How can this happen? By the way, there is another funny issue: if I use this "trick", the applications that should run in "fullscreen" (not really fullscreen, just the window that use all the screen size), like iTunes, don't do it anymore....

I have a Macbook Pro 13 inch 2010 model hooked up to a NEC Multisync EA231 WMI external monitor. The monitor is supposed to have a resolution of 1920 X 1080, but my computer only recognizes 1600 x 900 as the highest resolution. I've tried both mirrored and extended desktop, and I've also hooked up the monitor through a DVI adaptor and through a displayport cable. An Apple support person suggested using a dual-link DVI adaptor, but according to the Apple site this shouldn't be necessary for 1920 x 1080 resolution (I've also heard that it's a buggy piece of hardware). Any suggestions for getting optimal resolution?

I'm using a MacBook Pro OSX 10.6.4, have a simple dongle I purchased at the Mac Store which takes only DVI. The HP 2304 widescreen monitor only works with windows mirrored and has poor resolution - nothing like the 1440 Mac tells me I'm getting. I've used the build HP display adjustments with no joy. HP does not have Mac drivers for this display.

I have just connected an external 19" monitor to my 15" macbook pro. I am using both displays and that is fine, however I would like to be able to change the font sizes in my 19" monitor, because the default one is too small. I have to get awfully close to the monitor. I am not sure how i can display it better. When I tried changing resolution from 1440x900 to others, I didn't make it right, is that the only way? All I want is for screens in this monitor to have larger fonts (all programs, whether its safari, chrome, mail, etc). I should mention I am a brand new mac user.

I just started using my MacBook with an external monitor, and love this new set up. But, I have a quick question. When I hook it up, my screen looks like an enlarged version of what's shown on my smaller MacBook screen. This is okay, but I'd like everything (dock, menu bar, etc.) to be the same size as on the MacBook screen, only with extra desktop space, if that makes sense. Currently, since everything is just enlarged, I don't feel like I have any extra screen real estate - windows and the dock take up the same amount of space relative to the screen size as they do on the MacBook. My resolutions are 1280 x 800 on the MacBook and 1280 x 720 on the external monitor. I tried playing around with different resolutions but keep getting a No Signal error on the monitor when I use anything else. I know this is kind of a difficult question but does anybody have any ideas?

So I've had a 15" Unibody MBP since around November and I haven't been able to get it to work with my Hanns G 19" widescreen monitor. It should work at a 1440x900 resolution but its not even listed as an option when I hook it up. The monitor has both VGA and DVI inputs but I'm using the mini to VGA adapter (I picked up VGA to connect to a projector at school). I don't know if using the DVI adapter would do the trick or not and I'm not willing to waste $30 to find out as I'm a pretty poor college student at the moment.

I have a mbp 15" and it runs at 1200 x 800 (for example)let's say I have an external monitor which is 24" Can I run that external monitor at 1900 x 1200 (I don't know the real resolutions)would it work? If not, why? Is there a way I could make the MBP run at a higher resolution so it looks like iMac resolution?

I currently have a MBP1, 1 running 10.6.4 on an external monitor with the ideal resolution at 1920x1200. From time to time, when I wake my MBP from sleep through external keyboard/mouse to have it run solely on the external monitor, it sets the display at 1600x1200, so everything seems squished vertically. After a fresh reformat, the problem persists, though it is less frequent. It's just a minor annoyance that I can't seem to find a solution to fix permanently. I usually have to go to safe mode and adjust the resolution back to normal. Alternatively, only sometimes if I put it back to sleep and wake it up again with the external keyboard, it will detect the right settings.

I have my MacBook hooked up to an external monitor of 1920 x 1080 resolution. I don't use the MacBook screen at all. Every time I turn on my MacBook it displays on the external monitor as it should, but at the MacBook's 1280 x 800 resolution, which obviously looks nasty and stretched on the big monitor. I fix this by simply putting the Mac to sleep and pressing a key on my keyboard to wake it up again; and it loads in the proper resolution. Is there a way to make it display 1920 x 1080 on boot up without having to sleep and wake every single time? Keeping my MacBook in sleep mode when not in use isn't an option.

I have been having some problems with my Macbook Pro. I have a new BenQ screen connected to it via the Mini Display Port to VGA adapter from Apple. No matter what I do, I cant seem to be able to change the resolution to anything higher than 1280x1024, which is a pretty stupid resolution to have on a 27'' monitor. Sometimes when I plug it in, it gives me the option to change the resolution to 1920x1080.
But when I select it, the screen goes black and displays the message "No signal detected". Now, as it happens, I have a copy of windows installed on a partition of my hdd, and the screen works flawlessly on it. full HD with 75 Hertz. So that shows that it is not a hardware problem, it has to be a software problem. I tried everything, including reinstalling OS X, and deleting the "windowserver" files. no success.

I am connecting my Macbook on my HD TV but the osx does not detect the appropriate native resolution. MY Samsung TV has a native resolution of 1365x768 but the osx only detects and offers 1280 or 1920 (they both look really bad on my TV). I used a mini-DVI to DVI adapter and a DVI to HDMI cable. I also tried, without success, to create specific display settings using SwitchResX and DisplayConfigX. (10.5.2) I know that there is not a big difference between 1280 and 1365 but still, it's very annoying espacially that I my old PC with XP detected the right resolution as soon as connected it...

Recently I plugged my HD Monitor to my MacBook and the resolution changed (on the external monitor). I went to Display Preferences but I do not get any resolutions above 1600x1200. When I first used this monitor, I could use it at 1920x1080 and now I simply can't. I don't know if it's a PRAM issue. I reset it but nothing changed.
I'm using a HP 2309m monitor in VGA mode using the VGA-Mini display port adapter. I use the monitor with a PC in DVI mode, but I never use these connection at the same time. I noticed something. When I first used this monitor, Mac identified it as HP 2309 when I opened the display preferences. Now, it only recognizes it as Display.

I read this in a post elsewhere and am looking for a new 24 inch + monitor on a budget. I could ideally use the monitor for music work on my mac, my xbox and snes and for watching tv. "If I may offer one bit of advice about LCD monitors is that they only run optimally in their native resolution. You will need to get a large enough monitor to support this resolution for comfortable viewing or you can end up with tiny desktop icons. Reducing the resolution will likely degrade image quality." What does this mean given I have the unibody macbook pro 2.8 released around christmas 2008 with the best the better graphics card (whichever one that was).

Which will perform better on wow or any game, an imac 20inch or 24inch with the same spec of 2.66ghz 9400m 4gb memory?
They're both are almost identical but the native resolutions are different.I'm comparing a 20inch imac resolution 1680by1050 to a 24inch 1920by1200.
So I'm guessing the 9400m will do better on a 20inch imac right?
Since the 9400m is not all that powerful so I'm guessing it can't do well on the 1920by1200 when gaming ?

Here is what I am working with.
White MacBook (Late 2007)
Sylvania 22" LCD TV (1366X768 resolution)
Mini-DVI to HDMI
SwitchResX
So the problem is that the native resolution of the TV isn't a normal one. Called Apple. No help. Called Sylvania. Told me to call Apple. I've tried using SwitchResX to set the resolution to 1366X768 and have tried variations found on other websites (1368, 1360) but every time I restart it reverts back to 1080i. While 1080i works, the problem is that it is very hard on my eyes, and the text is hard to read, something I am assuming will hopefully be fixed when I get it to work at the native resolution.

I have recently purchased the mini display port to DVI adapter and a Belkin DVI to HDMI cable, to plug into my MacBook & Samsung SyncMaster 2032MW monitor. However when I connect this all up the display resolution is appalling, blurry and doesnt fit the screen. I have tried all the available resolutions turned mirror-mode on & off and its still shockingly bad! Also tried this on my LG TV and still the same. I have a Dell laptop which I connect via HDMI and the resolution is amazing. I thought the MacBook would output the same?

I was waiting to buy a new Macbook Pro but as soon as they were released today I said "meh" and decided maybe I should buy a brand new iMac and keep my Early 08 MBP. I want to get a new Mac in preparation for the upcoming launch of Steam on OS X and just because mine is long in the tooth for Windows gaming.
Anyways... I just had a thought and was wondering if any owners could clear it up. The resolution on the 27 i7 Quad Core seems ENORMOUS for a middle-grade ATI GPU. Are you able to game on high settings for semi-modern games like L4D2, TF2, etc. at the 27"'s native resolution? What are your thoughts on it as a gaming machine. It seems like the 27" will obsolete itself quicker than a i5/i7 21 inch (if one ever comes out) due to the screen resolution size.

im using a 27" imac... recently just bought a mini displayport to HDMI cable to hook it up to my 24" Benq 241 monitor.Im pretty sure ive used this monitor before without a problem on my old macbook. The monitors max resolution is : 1920 x 1200 but im only getting the option of :
1080i
1080p
720p
480i
480p
1600 x 900
1344 x 1008
.... the rest go down in numbers selecting 1080p gives a fuzzy picture... and 1080i, is what looks liek the highest - but still really pixellated?

I have a 27" iMac and have connected a Philips 160e as a pallette monitor via a Mini Display Port to VGA adaptor. the iMac sees it but auto picks the wrong resolution 1280 x 1024 (stretched) instead of the Philips' 1366 x 768 @ 60Hz.
If I try to change the resolution the screen goes black which is symptomatic of using the wrong refresh rate, and of course I can make no further adjustments. esc does not get me out of the black screen.
What is worse the iMac seems to remember the wrong resolution/refresh rate after restarts.
I have tried Safe Mode (it stayed black) and booting off an external hard drive into another system (back into black if I change the display settings).
I have gone into System Preferences > Display > Color >unchecked 'Show profiles for this display only' > selected > Philips 160E in the list
It only contains .icc profile information, which I suppose is to be expected but is the only access I can find to any specific model data. The same display works fine with an older 24" iMac, using a different adaptor because of the different display port.
Somewhere OSX is storing the settings for the external monitor, I'd love to be able to trash it or change it back.
Info:
iMac, Mac OS X (10.7.3), The closest you'll ever get to there, is here.

I'm a hardcore gamer that is a stickler for quality, and CRT is still the gold standard when it comes to a perfect image (not to mention the ability to run many resolutions without any quality degradation), but LCDs have come a long way. I'm likely making the switch to Mac (using Boot Camp for the few PC games I play, I mostly play consoles).
The iMac is the best fit for me but I'm concerned, when new games come out that exceed your system's specs you generally turn down the resolution to procure a quality image with a decent frame rate. 1920x1200 is a very high resolution with a lot of pixels, how much worse does the image get when turning the resolution down? Since it won't be at its native resolution I've heard that lowers image quality, but I have no personal experience since I've never used an LCD.
