MacBook Pro :: Cannot Change External Monitor Screen Resolution To 1920x1080

Mar 25, 2012

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.

MacBook Pro :: Unable To Change External Monitor Resolution?

Apr 6, 2012

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.

Hardware :: Setting 1920x1080 Screen Resolution On 2007 Macbook

Jul 29, 2009

The resolution on the monitor is 1920 by 1080 and the resolution on my Macbook is 1920 by 1200. Will the Macbook automatically adjust to 1080 or will there be some stretching or otherwise bad quality to accommodate the difference?

I don't have to have the latest and greatest technology, but I do want something that will look nice. I really like the HP monitors for the money and was hoping to get something around this size. I just want to make sure this isn't going to screw up the resolution or anything.

MacBook :: Won't Go 1920x1080 On External Monitor

Dec 7, 2010

I recently bought a Macbook, and I've been trying to connect it to my external Samsung SyncMaster P2270 screen using a DVI-to-miniDVI adapter from Apple. It works, both as extended or mirrored screen, but the maximum resolution I get is 1600x1200 (and I actually use 1600x900, cause it looks distorted otherwise).

Any clues on how to get it to output 1920x1080? I'm sure that the screen supports that resolution, because I've used it before with another laptop.

MacBook Pro :: Get 1920x1080 Resolution On A 22" Dell Monitor With A 13"

Sep 10, 2010

The highest resolution I can get at the moment is 1600x900 using a MacBook Pro, however I know that my monitor is capable of 1920x1080, as this is the resolution I used with my last computer which was a PC. I am using the Mini Display port to DVI adapter. The MacBook is fairly new. I bought it in April 2010.

MacBook Pro :: Able To Change Default Resolution On External Screen?

Jul 14, 2010

I'm thinking of getting a MBP 13'', together with an external display. That way I get the portability of a MBP 13'' while maintaining an in-house big external display and 400$ in my wallet, only losing a bit of processor power (which is found negligible by most users).

My question has to do with resolution. MBP 13'''s resolution is 1280 by 800, right? My question is: if I buy a display with higher resolution, will I be able to enjoy that resolution? Or no matter how big my external display's resolution is, will I always be stuck with 1280*800?

MacBook Pro :: 17" Unibody Outputting 1920x1080 Instead Of 1920x1200 To External Monitor

Jun 26, 2009

Just got a 17" unibody to replace my 15" Classic. It appears that the 17" can't output 1920x1200 over the mini DisplayPort to DVI connection, rather displaying 1920x1080. The 15" Classic has no problem outputting 1920x1200 which is the native resolution of this display (an LG L246WP).

What can I do? I tried downloading SwitchResX and fiddling around with that to no avail.

OS X V10.7 Lion :: Correcting External Monitor Screen Resolution?

May 9, 2012

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.

OS X V10.6 Snow Leopard :: 1920x1080 Not Possible For External Monitor After Update

Apr 1, 2012

Since I updated Snow Leopard to Version 10.6.8 on my MBP15, I can't use my SyncMaster P2770 HD (Samsung) in its highest 1920x1080 resolution anymore. I can choose 1920x1080 in the monitor-preferences, but having done that the resolution remains at 1680x1050 @60Hz (I can see it and even the monitor's info-menu says, that i still use 1680x1050 @60Hz). I use a Mini DisplayPort to VGA-Adapter and a VGA-cable.

OS X Mavericks :: Using AppleScript To Change Screen Resolution Of External Display

Jun 25, 2014

I'm trying to write an AppleScript to change the resolution of my external display from 1920x1080 to 800x600 and back to 1920x1080 (it has a few issues and this fixes them, but I'm tired of going into System Preferences to do this all the time).  I can get the script to open up System Preferences and option-click the scaled button (so all of the different resolutions come up), but I can't get it to select anything inside of the box where all of the different resolutions are (I can't find what I'm supposed to refer to it as anywhere and if I find something it doesn't work).  Here's the code I have right now:

tell application "System Preferences"

reveal anchor "displaysDisplayTab" of pane "com.apple.preference.displays"

end tell 

tell application "System Events" to tell process "System Preferences" to tell window "LCDTV16"

[code]...

I have a 15" Mid 2012 MacBook Pro (non-Retna) running OS 10.9.3.

MacBook :: External VGA LG Monitor Resolution

Feb 5, 2009

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..

MacBook Pro :: External Monitor Resolution To 1680x1050

Oct 27, 2010

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....

MacBook Pro :: Getting Optimal Resolution For External Monitor

May 19, 2010

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?

MacBook Pro :: Setting Right Resolution For External Monitor?

Apr 16, 2012

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.

MacBook :: Resolution With External Monitor - No Signal Error

May 17, 2009

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?

MacBook Pro :: External Monitor Resolution - Not Listed As Option

Jul 24, 2009

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.

MacBook Pro :: Wrong External Monitor Resolution - Right Settings

Aug 3, 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.

MacBook Pro :: Default Resolution On External Monitor - Proper Display

Feb 3, 2010

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.

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.

Hardware :: 1920x1080 Resolution Using USB Display Adapter?

Dec 25, 2009

I currently own a 27" Core i7 iMac and already have a 24" BENQ (M2400HD) connected to it via DisplayPort to DVI. I was wondering if using a USB to DVI to display adapter would work with the 1920x1080 resolution.

What I want to do is buy a USB to DVI to display adapter like the one here: [URL] and purchase the 21.5" M2200HD BENQ monitor to add as the third monitor. I want to be able to utilise the 21'5" native resolution of 1920x1080 with the USB display adapter.

On the OWC website, it states that the USB display adapter could support resolutions of up to 2048x1152. Do you think that it would be able to support 1920x1080? Most other USB display adapters seem to only support up to 1600x1200 or around there.

PowerPC :: Screen Resolution And Color Calibration / Grey Flickering Screen On Internal Monitor

Dec 5, 2007

Thing is I got hold of a 1ghz 17" iMac almost for free, it had a dead logicboard (I checked it with a voltage-meter), but I figured I could fix it and have a small hobby project-thingie going on. Well I just got a new logic board today, for a 1ghz 17" iMac g4.

Things is I only get a bright grey screen from my Mac when I boot. I've tried connecting it to a external display and that works fine. Everything is there.

I then reinstalled Tiger on it, with the computer connected to my external screen. And I still have the same problem. (I have now disconnected the ext. screen and is controlling the iMac from my MBP). So at least it isn't the installation.

So what is the problem? I can via an Apple Keyboard control the brightness on the blank screen, which would indicate that it does react to input of some degree.

I've read that if the inverter is dead or anything else is dead, you would get a rolling grey screen, flicker or something like that and not a steady bright grey. One thing I'm thinking is. What if somehow this logic board was for a 15" 1ghz imac g4? Can I check this?

I read that long thread about guys buying hi-res displays for their MBPs, and they had to replace some display profile? Could I maybe fix it with a different display profile-file?

I'm really confused by all this, and would appreciate any help I can get.

Model: PowerMac6,1
CPU-Type: PowerPC G4 (3.3)

and

the gfx chip is a GeforceMX4 with 32mb.

The display is a mode 9c27, manufacturer 610, serialnumber 00000, manufacture date: B84D7200.

OS X :: Cannot Select Appropriate Resolution For External Monitor

Aug 13, 2010

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.
