Hardware :: Wrong External Monitor Resolution - Everything Squished Vertically
Aug 12, 2010
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 a client with a fairly basic Mac Pro setup. He has the standard ATI 2600 graphics card connected to two 26 inch Samsung LCDs. The main monitor is ok, but the secondary monitor has about one inch of the far right side that does not work. The desktop area itself is squished in, and not chopped off. So far we have replaced the monitor with another, he has about a dozen at his disposal, we have replaced the VGA cable, and we have switched ports on the video card and re arranged the screen locations in system preferences. No matter what configuration we use, the screen on the right has it's image squished and makes many things look distorted.
Just curious if anyone else has had this issue, and what they've done to resolve it. We've contacted Apple care and they originally blamed the monitor, which is why we replaced the screen completely. At some point in the next couple weeks we may have a chance to bring the system to the Apple store, but then we'd need two monitors to demonstrate the problem.

I have the new macbook unibody, and use it from time to time to dsiplay things to an external montior, plasma, projector, etc. Using a mini-display adapter to a converter to get s-video was a challenge, but I figured it out. I have used this many times, as I am a DJ and need s-video out to connect to most devices.I was at an event saturday night, and the display on the external device (projector) kept displaying my desktop, NOT the external feed.
It was NOT set up for mirroring, as it seems like the displays were 'switched'. I had my desktop on the projector, and my external on my macbook pro monitor. I tried to fool around with arrangement and resolution, but to no avail. I understand that sometimes you have to drag your source to the right (of left) to get it to display on the external, and this was done, but it was still reversed.I know it was something simple to get the 2 switched back to the way it should be, but I could not figure it out. Any advice? None of my apple buds can figure this out.

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..

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 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 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.

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.

I just got my MaBook Pro (2.2 GHz and nVidia graphic card). I installed Boot Camp 1.3 and Vista. I have a Benq Monitor 24" with the native resolution of 1920x1080. The MBP is attached to the monitor via DVI.
The problem is that the max resolution Vista allows me to set up for the external monitor is: 1024 X 768. I have tried the original Vista driver from nVidia, but it wont recognize my hardware. Needless to say, that under Mac OS X everything works just fine.

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 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.

I'm in the process of replacing my MBP with an early 2k9 iMac as my DAW machine. I'm shopping around for external monitors, and I'm leaning a 27" monitor that natively displays 2048 x 1152. My question is, if I get a dual link dvi cable- will my iMac be able to display this resolution on an external monitor?

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?

So I tried to set up bootcamp on my 10.5.6 17" iMac. the windows installation failed because of a bad disc so I restored my computer using my OS X disc and time machine. Now my display in OS X is being forced to 1024x768 and I cannot change it to anything else. It looks terrible and there are some artifacts... Any idea what the heck happened?

I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode. I have reset the pram and tried booting in safe mode but that did not help me. From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen. Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?

G5 Quad

According to the screenshot, both Users (green) and System (red) uses 0,19% CPU each. Which means that idle (black) should be around 99%, which it clearly isn't. If I check each process individually, none is using more than 1% of CPU. The screenshot is taken after a reboot and I don't use and third-party background services like VMWare. It's Mac Pro 2.66 Quad (2009).

Historically I have had two matched monitors. I maintained two wallpaper folders, one for the left monitor and one for the right. My wallpaper cycled randomly taking pictures from the appropriate folders for the respective side once a day. I didn't use any add-ons, it was just the basic Desktop pane. It was perfect. Recently I purchased a lovely new monitor and decommissioned one of the old ones. The new monitor is widescreen so I made a third wallpaper folder for that one and set everything up to match the way it was before. Every day when the wallpaper refreshes, both monitors now pull from the same folder. I have deleted all but the widescreen folder from the list in System Preferences for the widescreen monitor and it still somehow keeps pulling its pictures from the same place as the remaining old monitor.
If I go into System Preferences, it shows that it's pointing at the widescreen folder correctly and manually clicking random on and off again to reselect a new wallpaper will pull it from the correct place. It's just when it's automatic that it screws up. I'm not sure I've explained this well, but the result is that I have to manually set the widescreen monitor's desktop picture each time or enjoy a horribly stretched image with the wrong alignment. In the long term I will replace the other old one so this won't be a problem (I'll just delete the wretched old folders entirely), but why is OSX going bonkers in this way when it's never had the problem. I could just decide on one static image until it's fixed but I like an element of chaos in my computing, just not a stretched image.

I have a 2.66 quad core 2009 Mac Pro. Running 10.6.2. I see weird behavior in the Activity Monitor. The "% idle" number jumps from 49% to 61% to 99% (but usually stays around 49%), when I'm actually 99% idle. The "% user" and "% system" just don't add up to "% idle." Does anyone else see this? I'm wondering if it has anything to do with the RAM I just installed, or if this is a coincidence.
