External monitor simply not working - including with external dock (dual screen)

I can't get the external monitor (aka dual screen) to work on my T60 via the VGA port. My model is currently running Windows XP and has a ATI Radeon X1300 video card.
I'm 6 months out of warantee (although this problem started while in warantee but I can't convince Lenovo of that).
I've tried the following:
- ensuring "extend my monitor onto this desktop" in windows display properties
- disabling/enabling Presentation Director and trying all the schemes
- setting all different combinations of modes for resolution/colour on both (LCD + VGA) monitor
- trying two different monitors and cables (which did work with other computers)
- Updating the video drivers (from the Lenovo website) and Presentation Director to the latest versions
I then figured it might be a hardware fault, so I tried to see if the external monitor was activated on bootup. I made sure the "LCD + VGA" option on boot was selected in BIOS. Still no joy.
Finally, I figured the actual VGA connector was broken so I bought a compatible mini docking station (port replicator) and attached the VGA cable to that and even that didn't work.
What on earth could be wrong if it's not the software and not the VGA connector? The video card is working as its powering the LCD display?
Is my only option to give it in to repair (I can't afford that)?

Hi,
Does the external connections and cables work with another system. I'd do that first.
If all of it works with another system then it could be drivers or internal things but try that first.
There are some driver updates on the Lenovo site. Make sure your BIOS are updated and such.
Good Luck,
Yup, checked the cables and monitor with another system (actually with the same laptop using a USB->VGA adaptor which isn't a long-term fix)
Also updated to all the latest driver including a BIOS update (which I forgot to mention).
thanks,
Michael

External VGA monitors are not working only with my Macbook Pro 2012mid version

Hi all,
I have a macbook pro 13' 2012mid version, running the latest version of Mavericks, 10.9.2. If I connect my macbook to any extrernal VGA monitor (I have tried 4 different monitors), then the external display is detected in system preferences, but the monitor is showing only black screen (no signal). I am 100% sure, that my minidisplay port, the cable and the monitors are working properly, cause if I boot the same macbook from bootcamp win7 partition, then external monitors are working well.
I have also tried the same miniDP VGA with an older macbook pro (I think it is a model from year 2011, but also running Mavericks 10.9.2) on the same displays and the monitors are working fine. So the problem must be with in my OS X.
A have also tried some things, that I found on the net, like booting with the plugged in monitors in safe mode, reseting pram, I tried different settings for the external monitor in the system preferences (resolution, refresh rate...) but nothing helped. External monitor stayed recognized in system preferences, but with black screen and no signal.

Your post is incredibly hard to read, font is way to small.
If you used Boot Camp Assistant to create a partition to install Windows to you need a REAL Windows 7 or 8 install media and license key and you have to actually install Windows on your Mac. Boot camp is only for creating a partition to install Windows and starting the Windows install from REAL Windows install media.
That Windows install media has to be a DVD disc, if your Mac has a built in DVD drive (Apple does not allow Windows to be install any other way on Mac computers that originally come with a built in DVD drive), or from a USB stick with the actual Windows install files on it (Not an ISO of the Windows install files).
So the question is did you install Windows on your Mac? It doesn't look like it from the Option key boot and the list of available Boot Devices you posted.

External monitor preview not working in CS5

Well its taken almost a month to get my Production premium suite CS5 working (exit code 7 install error) I finally reinstalled win7 pro after dicking with adobe tech support for weeks (they did try to be helpful and polite) and that "cured" the install problem so now I see that the external monitor preview still dosent work as in CS4....anyone know what gives? mine dosent work even if I set to external audio either. After effects-encore and Photoshop external firewire previews all work fine so I know its a bug in Premiere...anyone logged this yet?.On a VERY positive note I absolutely love the "solidity" of Premiere ....I invested in a Quadro fx3800 and well its a beautiful thing really.....is it odd to be in love with hardware and software
cheers y'all

this is a well known limitation of the current CUDA drivers. Adobe is hard at work with Nvidia to solve this, but the work around is to set MPE to software in your project settings. It has high priority AFAIK.
Wow thanks Harm that was the workaround for now ....brilliant

External monitor is not working correctly

I recently bought an external monitor and just hooked it up. It worked right the first time, and I had the screens mirrored. I tried to change the screen resolution and it went wack. It will not pick up a steady signal on the external monitor or the macbook pro when connected. I do not regain signal to my macbook pro until I either unplug the external monitor or turn it off it works on my roommates macbook pro. I can't even change the resolution to get it back to how it was originally because the computer freezes up.
Any help on what to do to fix this?

Hi Mike,
resetting the PRAM should return the resolution to its original settings (boot up the computer while holding down the "command", "option", "P" & "R" keys. Keep them held down until the startup chime has sounded at least twice.)
If this doesn't resolve it try resetting the SMC - see http://support.apple.com/kb/HT3964

10.7.3 external monitor "input not supported"

I have an external monitor connected with the Aplle VGA adaptor to my MBP.
It has been working fine for the last year.
Today I installed 10.7.3
And now I get the message "Input Not Supported" on the external display.
Not impressed.
Any ideas or do I have to roll back this update.
Cheers.

OK now it gets silly.
I have also had a problem, since I instaled Lion, that when I open my MBP the screen is black and no amount of encouragement will bring it to life.
So, I have to switch on my external monitor. My deskptop thern appears on the externam monitor, so I select "Detect Displays" from the menu bar and, kazam, my MBP screen comes to life and the desktop moves there.
It only remains for me to switch off the external monitor and wait for Apple to provide a fix.
Now, remember my current problem, in that the external monitor wil not work and shows "input not supported".
So today I opened my MBP and sadness, the screen is BLACK. So I switched on my external monitor and WAHEY! it worked and the desktop appeared on the external monitor.
Excited at the prospect that my problem had somehow magilcally fixed itself overnight, I selected "Detect Displays" and my MBP screen duly appeared and the desktop meved there.
The external monitor then stopped working and showed the message "Input Not Supported"
I also have a related VNC problem that is still outstanding, so I think it is fair to say that there are several issues around external monitors with Lion.

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3

HP Pavilion external monitor has stopped working with my Macbook Pro (Mid 2012) with OSX 10.8.3. When I purchased the monitor a few weeks ago it worked perfectly when computer was in clamshell mode or with lid open. Now external display has stopped working. When I turn on display it scans for signal but does not find it and then immediately goes into sleep mode. I am using a DVI connection with the adapter for the mini display plug. REALLY FRUSTRATING. Any help would be extremely appreciated.

Hi lancekatigbak,
If you're having issues with the display out on your MacBook Pro, you may want to take a look at the troubleshooting steps in the following article:

HT5019 Why can I not find a miniport to external monitor cable that works? I have bought for different types, two from Apple, cost me $300+ and still have no external monitor. Help, please.

What have you bought?
What model Mac are you running?
What input sources are available on the display you are connecting it to?

My w2207h HP Monitor is not working on my macbook pro with hdmi minidisplayport adapter. On Windows 7 via bootcamp it works. What can i do ?

As is said my HP w2207h monitor is not working with a minidisplayport to hdmi adapter and a hdmi cable which is working fine for my PS3. So the cable is not the problem. And on my TV i also have no problems at all activating a second monitor. Therefore the adapter isnt the problem either. When i plug it in the typical bluescreen appears. Then after a few seconds it appears again and there is no second monitor recognized. I also used the "recognize Monitor" button without success. Please help me, are there any special drivers or something like that ?
PS: bought a high end expensive adapter now because the old one was very cheap. But didnt help. Still stuck on the macbook not recognizing anything !

If you have an external drive you can hook up to the MacBook Pro I believe there *may* be a solution by getting an image to the MacBook Air.
On the MacBook Pro with the Windows install disk in the DVD drive fire up disk utility. Select the DVD and then hit the "New Image" button. Disk Utility should offer to create a disk image from the DVD. I would put that disk image on a USB drive connected to the Pro. You should be able to mount that image when you connect up to the Air. Hopefully BootCamp will be able to access that all through the process.
If that doesn't work (the drivers don't recognize the disk image once Windows gets underway for its install), you might try copying the installation files from the DVD to FAT32 formatted USB stick or drive and then using that to install Windows. I would expect Windows would be able to see the USB FAT32 drive and I don't believe any file on the drive is going to go beyond 4GB.
I haven't actually tried BootCamp on the Air, since I just use VMWare which has no issue installing from anything OSX can see. But BootCamp is going to eventually hand off operations to Windows and that's going to complicate matters--Windows has to be able to see the drive. While I believe there are drivers that let Windows connect to that drive, there's no way to authenticate (or even load the drivers I expect) before Windows itself is loaded--so it's a "chicken/egg" problem.

My Ipad 2 external speakers does not work and headphones has popping sound. This all occured at the same time as my Iphone and Ipod headphones only played mono (no, the "mono" option is not on). How can there be audio issue for all these devices?

My IPad 2 external speaker does not work and the original headphones have popping sound when used. This all occurred at the same time as my IPhone and IPod headphones only plays mono (and no, the "mono" option is not on) with the original headphones, as well as, other headphones tested. How can there be audio issue for all these devices at the same time?
As you may have noted from the list of Apple devices I own, I believed in the Apple and the products it was producing; but it is hard to believe from my experience and the other voices within the Apple Community that we are all experiencing the same hardware issues. Especially since I recently, I upgraded to an IPhone 4g (no, my faith in IPhone 5 series is very little) and is experiencing the same audio problem as described above. So now, I am off to the Apple store again to be told that it’s a hardware problem on new IPhone. Really? Apple, what happen to the pride in the product you were producing?

Everyone does things a little differently. I love to "jam " along with iTunes ( or old Lp's) . Always have. That's where/how I've learned to play .
I'm sure leonieDF is giving a proper way to jam along on a keyboard with an iTune. He blows my mind all the time with what he knows. Nuff respects to him !
What I do is make a GB project I call "Jam With". I'll make several new tracks that are blank. Just has a few instruments named in the blank tracks. You can change those per song ...
Because I'm not concerned about changing the pitch / key.... of the iTune or the tempo ... I can simply play along with it.
Peace,
P. Dreadie

External Monitor will not display full view MS apps.

I have a HDMI monitor that was previously working fine. The other day I went to use Word and Excel and the applications would only appear in the lower toolbar. When I would select them they would not enlarge. They remained in a thumbnail view. My email and Internet work as expected. Any ideas what's causing this?

IMac early 2008 screen not working properly, lots of lines on screen, re appearing and disappearing at random(normally slowly), computer fine on external screen, any suggestions?

This seemed to happen very suddenly; I left my iMac running while i went out and came in to find that the screen was totally unusable, as you will be able to see from the picture it has a lot of lines that seem to come and go a random and sometimes it goes black all together. What do you think is wrong with it? Logic board? Graphics card? Screen itself?.. also if it is the graphics card, is it separate to the logic board or do both need to be replaced?
Also some additional info:
iMac Early 2008
2.4ghz
4gb Ram
OSX 10.9.2
ATI Radion HD 2400
Actual computer working on external monitor, just not internal
Thanks

Costs vary by area, I think you may find out though that spending money on a 6+ year computer may not be worth it, you can buy an Apple Refurbished Mac with much more up-to-date specifications and save hundreds of $s. If this is of interest you can only find them on Apple's on-line store, in the US the current link is:
http://store.apple.com/us/browse/home/specialdeals
Then click the link to the iMacs. If you don't find one you want, continue looking the inventories change frequently, sometimes by the hour.

External Video option not working

Recently our Final Cut System crashed. We're running 10.5.7, FCP 6.0.6. We have an external JVC monitor that always worked before with Video Playback. Now we have no Video Playback options (we do not use Digital Cinema Desktop - but that is all that is currently available.). We have reinstalled FCP several times - the issue is NOT a) installation b) a JVC driver c) a faulty monitor (we see an image when we digitize footage). Footage is digitized through a Sony HDV 1080i deck. The deck is functionally normally. In fact, everything is functioning normally except that since we did the system reinstall we no longer have any video playback options behind Digital Cinema Desktop. The Help boys tried but I couldn't describe the problem any more clearly than this. The connections have been checked and indeed not changed. The Video Playback worked for six months previous to the crash. Does anyone know how we can recover External Video options? PS Important note - the External Video setting is set to OFF and will NOT reconnect to "All Frames" or "Single Frame". Thanks.

Are you trying to preview HDV? Or DV? I know you can preview HDV via firewire as DV...don't know how to do that...but someone does.

Imac doesn't recognize external monitor but was working

i had my HP monitor (HP 2011x) connected to my imac for about three months and when i went to move my monitors and imac to clean my desk, my imac no longer recognizes the monitor. all i did was shift the monitors to the left w/out unplugging any cables.
i've seen multiple threads about the same issue where the external monitor is no longer recognized and the majority of no solutions.
has anyone come up with a solution to this?
i restarted in safe mode to try and connect - no joy
i cleared the pram - no joy
any ideas?
thank you.

thanks man ... i might just do that. it is just aggravating b/c this problem seems to have been around for a long time (based on all the support forums threads started about it).
i went to the apple store this afternoon and verified my thunderbolt to hdmi was working and sure enough it was. i talked to two staff members there and they were equally as clueless why the external monitor is not being recognized via the cable.
