External display with native display

My macbook and my philips hdtv used to work perfectly together... the tv runs on the macbooks native resolution 1280x800... so there were never any problems... now my macbook won't allow me to run the native resolution on my telly... any suggestions... nothing has changed since it used to work except a updated leopard to 10.5.7... if apple have broken this then when are they going to fix it... its not like i'm trying to run something wierd and wonderful... just the same resolution as my macbook screen

Well, dunno what else.
So many posters have the same or similar problems since installing the OS 10.5.7 upgrade that the upgrade must be suspect.
Some have downgraded to the previous version and some problems have cleared up. Some have not.
We have almost identical monitors and MBs and you have a problem and I don't. And that's where it stands.
Hopefully, others may join in and help.
BTW, I had to spend some time with my Philips display, going through the setup with my remote, to get a good picture on it in PC mode. I guess you have tried that.

Problem with resolution of external display

Hi,
I am trying to use external display with my Unibody Aluminium Macbook Pro (NVIDIA GeForce 9400M, 2.26Gh, snow leopard). Cable setting I use is quite complicated as it is: macbook: minidisplay port>hdmi> DVI D : display. Display is LG Flatron W2242T (4:3).
So I hooked everything up and macbook detected display without any problem. The problem arises when it comes to resolution. Maximum resolution I can set (and in fact the only except 800xsomething) is 1152x870 and not only it is to low, but also it does not respect 4:3 ratio so it looks quite bad. So bad, that i cant really work on a setup like that. When I try to change resolution to any other, Display goes black. I tried using some apps, but they dont really work.
What can be the problem here? Is it connection?
I would appreciate any help.

And once you've cut thru the clutter of cables and adapters, remember the max you will be able to push the Flatron is its "native resolution", that happens to be:
Screen Size
22"
Screen Type
TFT LCD
Wide Screen
Yes
Brightness
300cd/m²
Contrast Ratio
8000:1
Viewing Angle
(Horizontal/Vertial)
160/160
Response Time
5ms
Resolution
1680X1050
Supported Colours
16.7M Colours
(data taken from LG's product page)
If you happen to have a late model MBP with the widescreen option, the Mac and the display will be on a 1:1 ratio, both are the same. Else, if you have a regular MBP, the monitor has more resolution than the Mac (1440x900) and distortion will occur if you do video mirroring.

External Display native resolution suddenly not available

Hello,
I'm using a Westinghouse LCM-22w3 external monitor with my MBP, connected via a DVI-to VGA adapter. I've used this computer/monitor setup for quite some time with no problem. Yesterday, I hooked my computer up to my 46" Samsung HDTV with no problem.
When I hooked my computer back up to the Westinghouse, the native resolution (1680x1050) was no longer available. Instead, the monitor hooks up at 1600x1000. Strangely, though, the EDID information appears to suggest that 1680x1050 should be available. Here's the EDID:

Any ideas? Switchresx didn't work, either

Well, you can move the file from the desktop back to its original location to at least get back to what you had before.
The file structure under Snow Leopard has changed and it's hard to keep up with this stuff. There is also now a com.apple.WindowServer.plist file in /System/Library/LaunchDaemons that you could try moving to the desktop and restarting. I dunno. Same rule applies.....if it doesn't help, move the file from the desktop back to its original location.

External display problems with snow leopard

I just upgraded from Leopard to Snow Leopard on my Macbook and it's created lots of problems with my LCD external display:
- The display won't work at its native resolution (1680x1050) - it will flash up an image for 1/10 of second and then go black. I can only get it to work at a lower resolution, which looks AWFUL.
- If I try to start up my Macbook with the lid closed and the display connected, the display won't work at all (it jams on the start up screen). It only works if I keep both of them running
I never had these problems when using Leopard. I've searched lots of forums and found that many people are having similar problems with external displays. Apple still haven't fixed the bug after repeated efforts from people to get if fixed.
Here are some threads (now closed) on this if you're looking for solutions:
http://discussions.apple.com/thread.jspa?threadID=2132912&tstart=0
http://discussions.apple.com/thread.jspa?threadID=2136455&tstart=1
http://discussions.apple.com/thread.jspa?threadID=2132837&tstart=0
http://discussions.apple.com/thread.jspa?messageID=10084332
Common suggested fixes are:
- Force OS X to use LCD font smoothing (does not work for me)
- Clear the PRAM on start-up (does not work for me)
- Delete /Library/Preferences/com.apple.windowserver.plist (does not work)
- Change energy management setting to high performance (only works on graphics cards in Macbook 15" and 17").
From reading these forums it appears that this is a well-know bug. Has anyone else got any suggestions to fix this? And why hasn't Apple fixed this yet after so many people bringing it to their attention? It's clearly a bug that wasn't in Leopard.

I'M FED UP WITH APPLE! They've always been a little shady, but the last half of 2010 took the cake!
First it was the iPhone 3g "upgrade" to IOS4 which was garbage and killed my ability to use the 3g until I figured out how to crack the software, wipe the thing clear then reinstall the original software. Next up was purchasing the iphone 4 as a Christmas gift for someone running tiger on their mac, only to find out that the iphone 4 doesn't work on tiger when they tried to sync their contacts - and then having to rush out and purchase snow leopard so that they could enjoy my gift. Then I install Snow Leopard (note - I purchased the family pack) onto my own leopard-running(10.5.+) powerbook only to have the external LCD display I've been using for years suddenly stop working.
Oh, okay, to be fair, it works IF I RESIGN MYSELF TO SET it to "mirror image" (which defeats the purpose of having multiple displays) and drop the resolution down to a pathetic, unsharp, nearly distored setting that is almost painful to look at knowing that this monitor was just A COUPLE OF DAYS AGO showing me crystal clear images.
Then I exhaust myself trying to find a fix only to discover that APPLE in their infinite brilliance (AKA - their torture of loyal customers) knows of the issue - worked it out - then created an update that created the issue all over again. I'm so done! No more macs. I'm going back to the evil land of PCs. At least there, you know you're getting crap, it doesn't sneak up on you after getting you to trust it time and time again.

Native resolution does not fill entire external display

I've got one of the original MacBook Pros with the Mobility Radeon X1600 hooked up to a Samsung P2350G display (it's a 23" LCD panel.) The native resolution on the display is 1920x1080.
The display has inputs for both VGA and DVI. The DVI port however is used by a desktop PC already, so I use a DVI to VGA adapter on the MacBook Pro, and use the laptop panel as a secondary display.
The problem is that when I set the external display to its native resolution, I get vertical letterboxing and some flickering along the edges of the image. It does not horizontally fill the whole display as it should. I have tried the same adapter on the PC and it worked fine (though with rather spotty image quality.)
Resolutions that are lower than 1920x1080 work fine and fill the whole display properly. I'm not exactly sure what the issue is. The laptop is only semipermanently attached to the large display so I can live with a reduced image quality there, but the flickering, slightly distorted image is just not acceptable right now.

Sounds like it might be a sync issue. Have you tried powering the monitor off and then back on with the MBP connected to it? How about just temporarily disconnecting the DVI cable from the desktop PC and using that to plug into the MBP.

Unable to use external display native resolution

Dear all,
Here is the current setup I'm using :
MacbookPro 15", hi res, Mid 2010 with Mac OS 10.6.6, software up-to-date
Apple MiniDisplayPort to VGA Adapter Firmware 1.03
IIYAMA Prolite E2607WSD, a 26" monitor with native resolution of 1920x1200 @ 60Hz
When connecting the MiniDisplayPort to VGA adapter to the VGA cable, the MBP doesn't enable me to set the external native monitor resolution of 1920x1200 with extended desktop. The maximum available resolution the macbookpro is able to diaply is 1920x1080.
What I tried :
-using high performance graphics in the energy saver settings
-using clamshell mode
-using mirroring mode
-reset PRAM
-reset SCM
-delete com.windowserver.plist
-use SwitchResX.app and DisplayConfigX.app to force the native resolution
To make sure that the monitor was correctly behaving, I tried with a PC with WinXP, and I was able to get max resolution of 1920x1200 without an issue. I also tried with a Macbook 2008 with 10.5.6, and with it's own DisplayPort to VGA adapter (the "normal size" one, not the "mini" one I'm using with the MBP), and it worked as well with the native resolution of 1920x1200.
I 'm coming to the conclusion that either the minidisplayport to vga adapter doesn't accept any resolution higher than 1920x1080 or that the one I bought from Apple is not properly working, or that I should use the minidisplay port to DVI adapter (no HDMI here as an input for the monitor)...
I also browsed the forum and found a lot of similar issues, so I guess it's pretty common, but no workaround seems possible.
Does anybody in the community had the same issue and know how to solve it ?
Thanks in advance.

Hello BSteely,
I actually tried to get the EDID information and to replicate them as much as possible but everytime I tried a custom resolution, after reboot, SRX will say " the system didn't accept this setup"... and the proper resolution is not available..

External displays with similar pixel density to 17" MBP display?

I've got a 17" MacBook Pro, native resolution 1920x1200, which is quite high in terms of pixel density. I have a 24" external Samsung display, also 1920x1200, which means the pixel density is lower. It works fine, but (as you might expect), screen items increase in size rather noticeably when I drag from the laptop display to the external display. (The 24" LCD Apple Cinema Display is also 1920x1200, so the same thing would happen). I've been looking all over the place, and I can't seem to find an external display in the 20-24" range that has a resolution higher than 1920x1200. Ideally I'd like to find a display with the same amazing pixel density, so everything is the same size on both my laptop display and on the external display. I don't know what that would be--probably something like 2048x1152 on a 20" or 22", and 2560x1600 for a 24". Even Apple's 30" Cinema Display at 2560x1600 (or what I imagine will be the new 27" LCD coming out later this summer, probably at 2560x1600) would suffer from this problem, because while the resolution is great, the screen size is so large that the pixel density is lower and once again screen items would increase in size when moved from the laptop monitor to the external monitor. I don't really care about screen size or cost. I'd buy a 20" display, or a 30" display, at pretty much any price, if the pixel density were identical to my MacBook Pro. Anybody know where I can find something like this?

The pixel densities of the 15" hi-res MBP at 1680 x 1050 and the 17" at 1920 x 1200 are really quite extreme — the 17" slightly more so than the 15". To read the "fine print" on those screens without a resolution-independent user interface (which the Mac OS doesn't yet offer), most users have to sit closer to those displays than they'd want to be to a 27" or 30" display, simply because for a viewer sitting that close to it, the bigger display would extend outward beyond the central field of sharply focused vision. One would constantly be leaning forward and back: in to read the menus or palettes and then out to see the whole screen. That would be pretty tiring. Thus I think it's quite unlikely that we'll ever see 30", 27" or maybe even 24" displays from Apple or anyone else at the same pixel density as the highest-resolution MBPs: 133.2 pixels per inch for the 17" and 128.6 for the 15", compared with 108.8 for the 27" iMac and 97.7 for the 30" Cinema Display). The current standard-resolution 15" MBP at 110.3 actually has a lower pixel density than the 13", at 113.5.
Interestingly, the current 24" Apple LED-backlit display at 113.2 has almost exactly the same pixel density as the 13" MacBook Pro screen. For someone who wanted things to stay the same size when moving from screen to screen, that would be an ideal pairing. But the 13" MBP sure wouldn't be any match for the 17" in terms of screen real estate when each was being used as a stand-alone portable.

Display only on external monitor with laptop open--possible?

I have an external monitor (20" with resolution of 1680 x 1050) attached via DVI-D to my MacBook Pro 15". When I'm using it in this configuration, I like to only use my external monitor and not the built-in laptop display. The only way I can get this to work is to close the laptop screen and then wake up the computer using an externally attached (bluetooth, actually) keyboard.
My question is, how can I do this and have my laptop screen open? Whenever the laptop screen is open, its built-in screen activates and I can either "mirror" the displays or have display spanning. Mirroring does not work well for me because the external monitor's native LCD resolution is 1680 x 1050 and the laptop is 14xx by something (I forget the number).
Why do I want the screen to be open? Better airport and bluetooth reception. My external monitor is far away enough from the laptop that sometimes, the bluetooth mouse gets jittery when it tracks.
Thanks for the help!

How about turning the
brightness on the MBP all the way down? Will that
achieve what you want?

Well, that means using monitor spanning. In that case, I could certainly make my external monitor the main display (thus, the one with the menu bar). The problem with monitor spanning in my situation is that it is possible windows and icons be mis-located to the laptop monitor. Because my two displays are not sitting side-by-side (they are at least 5 feet away from each other) this could get confusing.

Portege Z30-A-18M - cannot set native resolution on external display

Hi,
I have tried to connect two different full HD displays to my Portege Z30-A-18M and I was unable to set the native resolution - maximal resolution that I can set for those is 1680x1050... I wasn't so surprised with the first one as I had some troubles with native resolution when I was connecting it to the Satellite laptop that I had before. But then the same happened when I tried the other display.
I thought that this laptop can handle higher external resolution... Is there a way how to force the native resolution for the external diplays in Windows 7?
Thanks!

Well, I wanted to use it as extended desktop... But I tried now to set it only to external device and I am still getting 1680x1050 as max
Just a note, the first display was connected with analog (D-SUB) and the second with digital (HDMI) ...
Is there a way how to override the maximum and set my own custom resolution?

IMac Retina 5K (2015) with 1xTDM iMac (2011) and 1x Dell External Display possible?

I have 1 x 27" iMac Retina 5K (2015), 1 x 27 " iMac (mid 2011) and a Dell P2715Q. I'd like to know if it's possible to run the 2011 iMac in Target Display Mode and my Dell as a secondary display from my 2015 iMac? My desired configuration is the 2015 iMac running two external displays. The 2015 iMac has an AMD Radeon R9 M295X 4GB Gfx card and both iMacs are running Yosemite 10.10.1
I have verified that running the 2011 iMac only via TDM works. Also running the Dell as an external Display only works (either at 4K resolution or the same resolution as the external iMac (2560x1440) via SwitchResX). With the Dell running @ 2560x1440, trying to put the 2011 iMac into TDM, causes a slow grey screen, then some display artefacts when coming out of TDM. Going in and out again appears to refresh the screen. But it doesn't seem to work.
I was wondering if anyone else has a similar configuration working and if so what settings or configuration changes to make?
Thanks!

I stopped by the Apple Store yesterday, and they were nice enough to try the Screen Sharing solution with me.
Indeed, we were able to share the screen of a MacBook Pro and display it on the iMac Retina 5K over a Thunderbolt Bridge network. (should also work over WiFi)
As I expected, (based on the native resolutions) the MBP window maxed out at about 55-60% of the height and width of the 5K display.
I didn't try experimenting with lower resolutions on the 5K.
I'd actually be OK with that solution except as we increased the font sizes, (e.g. 48 pt) we noticed a *lot* of ghosting around the characters.
I will have to try it again at normal font sizes and decide if that is something I can work with all day long.
Otherwise, I am leaning towards buying last year's iMac, which kinda' grates me the wrong way.
Thanks,

How do i use an external display with my macbook pro?

How do I use an external display with a macbook pro?

Just buy the proper adapter cord, such as MiniDisplay port to HDMI for example. Plug it in and it will be automatically recognized. Use System Preferences > Displays to set options.
The display can Mirror your primary desktop or Extend the Desktop.

How do I view an external display with my macbook pro closed?

How do I view an external display with my macbook pro closed? I am using a wireless keyboard and trackpad, and I would like to use a larger (Dell) monitor with my Macbook Pro closed.

Here are the rules for Clamshell mode:

How can I disable the internal display on my MacBook Pro with connected external display?

I used this metod with the MagSafe power cable connected (see http://osxdaily.com/2012/06/15/yet-another-way-to-turn-off-internal-lcd-display- of-macbook-pro-with-lid-open/).
Open System Preferences and click “Mission Control”, then click on “Hot Corners”
Select a hot corner and pull down the menu to select “Put Display to Sleep”
Now connect the external display to the Mac and move the cursor to the newly created sleep corner to turn off the internal display
Close the MacBook lid and wait a few seconds before opening the lid again, the internal display should stay off while the external display will be powered on
This worked great under Mac OS X 10.7.4, but after the last update to 10.7.5 it doesn’t work more. The built-in display turns off really, but a few seconds after opening the lid it lights up again. Do you have any suggestions? Dimming the brightness or clamshell mode is not very useful.

Thanks!

I have the same problem: not able to work with my external display mirroring the internal one - while shutting the internal display off.
I believe there is an issue with Mac OS X Lion 7.5 that Apple needs to solve, since apparently it does not happen with this version of the OS only...
https://discussions.apple.com/thread/4315808?start=45&tstart=0
Or any other way to solve it?

How can i drive 2 external displays with my macbook pro?

I just purchased an Macbook Pro and wanted to know if there is a solution to drive 2 external Apple
Cinema Displays simultaeously. (Set up so displays operate as 1)?

I believe the TripleHead2GO requires all three external displays to be identical. Verify this with a call to Matrox. There is also a maximum resolution limit for the three displays together, which you'll want to be sure is acceptable to you and will look OK on your monitors. Ideally, the maximum resolution the TH2Go supports for each display will be the maximum resolution each display is capable of when used alone, because the displays will be sharpest at their maximum resolutions. If used at any lower resolution setting, they will be noticeably blurry.
I'm not aware of any other three-display options for the Mac that enable the monitors to operate with normal responsiveness (USB video adapters are slow). Yes, the TH2Go is expensive, and that's probably because it's the only game in town.

Connection to external display does not work under windows bootcamp, with a thunderbolt to vga adapter.

Hello guys, after searching a lot in the forum for an answer to this, I could not find a solution so this is the reason for this post.
I have a Macbook Pro (early 2011 I think) running MacOSX Lion and I have installed Windows 7 64-bit through bootcamp (version 4.0).
Everything works fine except that I cannot connect my external display through my thunderbolt-vga adapter.
The external monitor shows only the boot screen of windows (the one with the windows logo) and then, when I get into the login page it goes blank.
After reading the forum, I have done several things in order to fix this problem such as:
Restarting the macbook with the thunderbolt device connected to it.
Updated to the latest ATI drivers through bootcamp.
Removed the graphics driver and re-install it again.
I have tried to identify the external monitor through windows 'screen resolution' tool (attached photo).
but still no luck.
Does anyone have any idea on what else I could do in order to fix this? By the way, I find it very frustrating that Apple does not have a stable solution to the problem with devices that are connected to the thunderbolt port.
Thank you in advance

and here is the attached screenshot

Mid 2010 15" MBP becomes unresponsive with black screen while plugged into external display?

I have a mid 2010 Macbook Pro, which is 15" and has the 2.66GHZ i7 processor configuration.
Had it for almost a year: No problems
Until about a month ago, laptop began becoming slow to boot, crashing. checked the harddisks, were corrupted and it needed a complete re-install of Snow Leopard. Did this and it seems to be ok ALTHOUGH:
I recently purchased a TEAC LCD TV which i have been using as an external display for my macbook, but have found that while the LCD TV is plugged in and i am using a dual-screen setup my computer and BOTH displays will quite often go black, and macbook will become completely unresponive
This sometimes happens apparantly randomly, but mostly happens when i have been using the external display for a while (30mins+) and use the "Display all Windows" feature of OSX.
I am connecting the macbook to the LCD TV with an Apple Mini-DisplayPort to DVD-D adaptor, which is then plugged into a DVD-D to HDMI adaptor
(As TV has no DVD-D input and i didnt (at the time) want to spend $50 on a Mini-DisplayPort to HDMI adaptor) Could this multiple line of adaptors be causing a problem? surely it wouldnt cause the macbook to die...
Can anybody help me? i have looked all over the internet for anyone with a similar problem with no avail.

UPDATE: This has happened to my macbook again while not plugged into my external monitor and with nothing else plugged in to it expect a USB mouse.
Here is a status report from when i rebooted about 15 minutes ago (Plugged into TEAC LDC, went to 'show all windows' crashhhh..) dont know if there are any clues in here:
