External display questions

I'm thinking of buying an LCD monitor to play Wow on with my macbook. Does the macbook support having two monitors (one with the game, the other

Toggling Mirrored Mode is the closest answer I found, but you are stuck with the lowest common resolution. I was really wondering about terminating the signal to the external display without disconnecting cables. Most LCD externals will go to sleep or low power mode after a while if there is no signal. As an example, If you connect an external display, it will not become active until you press "Detect Displays." I was wondering if you could somehow "Un-Detect Displays" or "Ignore External Displays"

Question about using HD LCD TV 1080p as external display

When i connect my MacBook to my new Samsung LCD HD TV, it set the screen resolution correctly to 1080p. The picture seems very nice, but when I move some text to the big screen the text is not so clear.
Why not? Am I doing something wrong or can I do something to make the picture (text) nicer?

Screen resolution, in general, is a hard thing to explain to individuals who don't work in graphics manipulation, and for good reason. It seems backwards at times. How is it that a 36" 1080p TV can appear blurrier than a 24" 720p TV? Why is 720p better than 1080i?
As far as using a 1080p display with my computer, I've settled on a 24" Samsung 1080p monitor/tv. I find it's a good balance between pricing, ppi, readability and other factors that one might consider important when looking at external display options.
Frankly, modern computer OS GUIs are not designed to be used on a display that is upwards of 8 or 12 feet away from you, no matter how big it is, or how high its resolution is. They take advantage of high resolution displays so that sitting close to a screen is less taxing on your sight over time. There are alternatives, obviously, like Media Center and Apple's media software, which are designed for using a computer on a television.

Question regarding external display

Hello,
I may have posted this in the wrong section, but the forums are labeled oddly. Anyway, I have an Insignia flat screen that I'd like to use as a second monitor for my laptop. However, I have no clue if this laptop can even use one.
Here's some information about my laptop - http://i.imgur.com/yHlcLsO.png
If it can use an external display such as a tv, what cord do I need? I am not seeing an HDMI port. The HDMI port I'm used to, which was from my old laptop, had the two holes on the side for the screws or whatever you call them.
Thanks.

The Ideapad U530 has an HDMI connector. What you were using before was old school vga which uses a D-sub connector or DVI. Using HDMI should give you much better clarity and response.
d-sub/vga = http://www.mouser.com/images/switchcraft/images/ehhd15ffb.jpg
HDMI connector = http://www.mouser.com/images/molex/images/highprofile_SMT_iso.jpg
DVI connector = http://www.mouser.com/images/omron/images/xm4m_t.jpg
HDMI cable = http://i.ebayimg.com/00/s/NTAwWDUwMA==/z/FA0AAOSwg3FUhO1~/$_12.JPG
The TV should have an HDMI connector, on it unless it is older then 5 years than it may be iffy, and you just need to get one of these. Should be able to get one pretty much anywhere. radioshack, walmart, kmart, etc. anyplace that sells tv's should have them. Just keep in mind that if thier charging more then 20$ for it that is too much.

Question about external displays.

Just curious about external display use with the macbook.
I want to link up using DVI to DVI but I recently read that my external display will only show the same as the macbook display, and that i cant use the macbook display, and the external display as two seperate screens? but i read its possible to do on the macbook pro. Is this correct?

I don't normally use my macbook with my primary display, but I have tried it out.
I hooked it up via vga, rather than dvi though.
It worked fine, but defaulted to mirrored. There is an option in the settings to disable mirroring, and use the macbook as the primary and the external as the secondary.
I haven't found any way to swap them, and have the macbook as the secondary display.
The management of the screens was pretty cool though. You can drag and drop the screens so their relative position is set up how you want it (over/under, left/right, etc).
hope that this helps...

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.

How do I get my Macbook Pro to detect an external display?

Hi there.
I just bought a new MacBook Pro today.
Everything about it is wonderful, except: When I plug an external display into the Thunderbolt port using a Minidisplay port to VGA adapter, it doesn't send a signal to the external monitor. The screen on my Macbook will go blue for a second, and then the windows freeze. The mouse will be movable for a bit (up to a minute), but nothing is clickable. Strangely, it seems as though it's functioning as if there were a second monitor (I can move the mouse off-screen as though it's going over to another display). But then the spinning rainbow wheel starts and never stops. If I unplug the Minidisplay port to VGA adapter, the Macbook will snap back into professional mode and everything works again.
If I try to boot the computer up with the Minidisplay port to VGA adapter already pluged in, it simply won't boot up (I get a gray screen with an apple and nothing more).
I tried using gfxCardStatus set to "discreet only" and I still have this problem. I tried to run a firmware update, but my comp seems to be entirely up-to-date already (just set it up today).
The monitor and adapter seem to be working fine, and function as an external display when pluged into the Mini-DVI port on my 2009 Macbook running Snow Leopard.
I guess my question is, what's causing this? Is this an adapter problem? Like, do I need a special adapter to use with a Thunderbolt port as opposed to the one I'm using which works when pluged into a Mini-DVI port?

The only thing that I can suggest is trying a different adapter - such as this one from Monoprice.
I don't know if that's the root of your problem, though. Does the external monitor have DVI? You could get a Thunderbolt to DVI adapter from Monoprice - here - and give that a shot.

External display via Mini DisplayPort to DVI no longer works with MacBook.

I had not used my external monitor in the last several weeks. I believe there have been a few OSX Lion updates since the last time I used the external monitor. I had installed all the updates prior to connecting my external monitor again. However, a few days ago I tried to connect the external monitor and all I get is a "No Signal" message on my external monitor. The Mini DisplayPort to HDMI works on my LCD TV, so I know the MDP works. I have also replaced the MDP-to-DVI cord and the external display still doesn't work.
I connected the external monitor to another computer running Snow Leopard and the external monitor works. So, the external monitor does work.
I have seen a few posts aboout this, but nobody seems to have a solution that works or is directly on point to my issue. I have tried to use all the scenarios for plugging in the external monitor and external monitor power. I tried to reboot the laptop with and withoout the external monitor connected. Same thing with the exteernal monitor plugged in and no power, etc. Nothing works. I have tried to repeatedly turn the external monitor on and off while connected to the MacBook. Again, that doesn't work.
So, I am open to any help someone may have. Here is what I am running:
MacBook, Aluminum 13" Late 2008

NVIDIA GeForce 9400M

How to restore display on MacBook Pro to original settings after faulty external display connection

Rookie question, 2009 MacBook Pro. We bought a dvi-VGA adapter to connect to an external display. Got a picture on the external monitor but very poor resolution. Meanwhile the display on the MacBook Pro re-set itself and we were not able to restore it to normal even after we disconnected the external monitor. We now have our MacBook Pro with messed up resolution and display, AND no external display. How do we get the MacBook Pro back to its default display settings? Any help greatly appreciated!

Re: MacBook doesn't sleep when closing lid with external monitor attached with Lion Oct 14, 2011 7:01 PM (in response to admgtz)
I would like to offer this solution. I have a MacBook Pro with an external monitor, and, for a year and a half both displays slept when I closed the MBPS. This behavior stopped when I installed Lion. They would sleep when I removed the power cord, but what a pain that would be. The command "pmset -g assertions" gave no indication of which process ought be preventing sleep.
I contacted Apple support, and after some searching, the guy working with me found this thread, which was flagged as an Apple-approved solution:
https://discussions.apple.com/thread/3190417?start=165&tstart=0

Aug 31, 2011 9:56 AM (in response to Bob_viking)
Here's the command to make your laptop behave like it did Pre-Lion (courtesy of my friend):
sudo nvram boot-args="iog=0x0"
Works perfectly for me. If it screws up your system, just zap the PRAM next boot (cmd-opt-p-r) and you'll be back to the default Lion state. Or if you can still get into terminal, this command will get you back to Lion's default state as well:
sudo nvram -d boot-args
Enjoy!
One snag was that I had to run it with the external monitor disabled, but it worked great!

MacBook Pro 13" Early 2011 - External display issues

I have an early 2011 MacBook Pro 13" (2.7GHz version) that I am using with an external non-Apple display. I am having issues when MBP goes to sleep or trys to sleep the display. The external display exibits one of a number of problems: goes dark but does not power off the backlight or freezes up and requires being powered off then back on. My display is an ASUS VW266H but it seems like this problem, or other similar problems, are happening with other non-Apple displays.
In calling Apple tech support of 5/27/11 they indicated that this is a known bug and they are working on a fix. There was software update released 5/4/11 to "improve graphics stability, address issues with external display" named MacBook Pro Software Update 1.4 (http://support.apple.com/kb/DL1382). I downloaded this and applied it but it made no difference.
I experienced these problems with three different video adapters: Apple's own mini DP to DVI, Belkin mini DP to HDMI and another brand of mini DP to HDMI also sold by the Apple store.
So the questions are:
1) Will Apple release another updated to address this incompatability or are they done with the issue given that they released the update mentioned above?
2) Has anyone compiled a list of monitors that are know to work with these most recent MacBook Pros (the early 2011 versions with the Thunderbolt/mini DP combined ports)?
If you have used the MacBook Pro 13" early 2011 with an external monitor please respond to this post with your experiences so we can all know what works.

With my new 2011 13" MBP I'm having no latency issues using my '08 Samsung SyncMaster 2253BW DVI (digital) monitor. Sleep function awakens fine, goes to sleep 3-4 sec.
I'm using a cheapie model Syba MDP to DVI connector; here on Amazon:

I bought 2 in case one craps out on me...knock on wood. Good luck hope you find a solution.

Can I use External Display on a Window 7 64bit 13" Macbook Pro Early 2010

I have a 23" LED LG Monitor , It has VGA Cable , RCA Cable and HDMI Plug (but no wire). I am asking now if whether I should need a VGA Cable or a RCA Cable or a HDMI cable. I know there's the Apple Mini DVI to VGA Adapter. Should I get that? And does window 7 64bit professional bootcamp support any external display? If not , is there another way to get it working.

You should be able to hook it right up just like if it was a "normal" Windows Laptop.
Windows would be the one to set it up with. Make sure you've updated Boot Camp.
You probably should use an "Apple Mini Display" port -to- HDMI adapter as that should give you more display options, etc. (I'm not sure how high the 13" can go on resolutions, HDMI or VGA may not matter?)
You MAY have to use a separate sound cable between the laptop and monitor as some HDMI -to- (whatever) adapters don't carry the sound signal via an "adapter".
The next choice would be a Mini Display port to VGA adapter.
You may want to also ask this question in the "Computing Hardware/MacBook Pro" area as they may have more info?
Hope this helps...

External Display (Mini Displayport) doesn't work

I have a mid-2010 13" MacBook Pro. The Mini DisplayPort sends NO signal to an external display, either adapted to VGA, DVI, or HDMI.
I've tried two separate displays (neither Apple branded), one of which is brand new, and both work perfectly well with my iMac and Mac Mini . . . but, nadda with my MacBook Pro.
I brought it in to the Apple Store in Belfast last week and the Genius Bar did the normal testing on it ... where it failed when hooked-up to a basic VGA LCD screen.
... BUT ... when they connected it to an Apple branded display it worked immediately.
Well, that's SOMEWHAT good news ... however, I have no intention of buying an Apple display (uhh ... yet).
I've scoured the newsgroups and discussions for an answer, but all the answers I found didn't help me.
Yep, it WORKS when connected to an Apple display, but that's it. And, the cabling and displays I'm using work fine connected to my other Macs.
"Detect Display" (holding down the ALT key to make it appear) does nothing for me.
I've tried Safe Mode boot ... no help.
I've tried with and without mains power (to the MacBook), and the results are the same both ways.
I've tried resetting the PRAM ... no help.
The fella at the Apple Store was stumped. They are willing to examine the machine and let me know what they find, but, this is my primary working machine and I don't have the luxury of such down-time without it.
Any thoughts? Any obvious (or, not-so-obvious) tricks you can finally think of? (short of buying an Apple display)
Thanks

I knew that, Jin Li Thanks for the pic.
The question is whether hellothere's machine has thunderbolt. If my theory is right, then switching tb off might not help, since the problem would be with one of the video components (in the TV or the computer) not recognizing the other as a trusted make/model.

Laptop Built In Display and External Display not Working

Hi all, I have a HP Envy M6-1158ca, and recently my Built-in display stopped working. I plugged it into an external display via HDMI and it showed no input. It seems as though the laptop is not booting into Windows either, as usually whenever my laptop boots into windows, the fingerprint scanner blinks letting me know I can now sign in using it. I am extremly frustrated with this, and have an unbelieveable amount of stress because this was my only PC. Please respond as soon as possible, it would be much appreciated.
Thanks in advance.

Yes.. i think thats what might have damaged it...Notebook should always be completely powered off with the battery out and ac adapter disconnected while replacing any internal hardware..
Shouldnt be a BIOS problem....but still you can check this link..

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.

Download the patch-edid.rb script from the forums thread above and put it in your home directory.
Connect only the external monitor(s) in question (I closed my MacBook lid, for example). The script will make override files for any connected monitor.
Type “ruby patch-edid.rb” in Terminal.
A new folder will be created in your home directory. Move it into the “/System/Library/Displays/Overrides” folder. If Finder tells you that you are overwriting an existing folder, consider backing it up first.
Restart your computer, enjoy your monitor.
To undo the changes, either delete the folder you had copied to the Overrides folder (if it didn’t already exist) or replace it with the folder you had backed up.
