X200 Display Port Issue

Hi,
I am new here - so I hope this is the right place to ask.
I own a Thinkpad X200 with Ultrabase, running WIN7 with a Intel Based Graphics Accelerator ... I am pretty happy with it beside one issue. Since a while I have 2 Monitors connected - one VGA and one on a Displayport. Both work correctly when I boot in the Ultrabase.
Problem beginns, when I pull it out of the Ultrabase, and try to connect to Projector ... It seems like the X200 still is the opinion, that the Monitor on the displayport is still conected and it will not connect to the projector like I want it to. Other issue is, if I Bood outside the ultrabase, I have to disconecct the Display Port adapter pyhsicaly to get the both monitors working... I tried it with several adapter --- Original IBM and others - no difference. What do I do wrong? Googeling the issue did not bring anything up.
Thanks in advance for your help and patience.
Kai

Try resetting the SMC, followed by a PRAM & NVRAN reset.

W540 and Ultradock Display Port Issue with Monoprice 27" Monitor

Hi,
I have been troubleshooting an issue with my W540 and Ultradock for over a month now.
The issue is that the display port will not recognize my Monoprice 27" monitor. This same monitor was working previously with my W520 and a different dock (ThinkPad Mini Dock Plus Series 3) through the same display adapter. The current monitor will work on the DVI port, but I obviously can't get the full resolution of the monitor without the display port adapter.
So far I have tried:
1) Updating the drivers of the laptop
2) Updating the drivers of the dock itself to 2.22
3) Power cycling the monitor with the PC connected, not connected, etc.
4) Switching between Standard/Advanced mode in the BIOS
5) Nearly every iteration of monitor detection in the screen resolution settings
6) Changing cables, adapters, and display ports
What is different in my scenario (based off of the other issues I've seen with the Ultradock and W540) is that the monitor is never even detected under any circumstance through the display port. Device manager never sees it, nor does the normal monitor detection procedure.
Any help would be greatly appreciated.
Best,
Austin

Any ideas?
I am about to throw this in the trash... It's now defaulting my DVI port monitor to 640x480 without the option to change it.

Mini display port to HDMI - negative picture issue

I bought a new Macbook Pro 13,3 inch laptop last week and added a 120 GB ssd and 8 GB of RAM. I'm loving it!
Something I'm not loving however is the issue with the Mini Display Port / Thunderbolt when connecting with a MDP-HDMI adaptor. I watch a lot of movies and so hooking the computer up to my Sony BRAVIA 46 inch TV is quite important. Everytime I do the picture and sound are great! For about 5 minutes... then the picture goes "negative" you know that turqoise look?? Like a negative image. The sound is still there, the picture is just affected. To remedy I have to turn the tv off and restart the movie. Very annoying doing this ever 4-5 minutes!!
Is there a fix of some sort? Apple should really release an update for this.
Thanks!

sounds more like a hardware failure.
Try a different monitor to see if the problem persists, in which case that would point to a bad video card... or try a different source with your monitor(another computer), and if the problem persists, that would indicate a problem with the monitor

Mini Display Port to VGA Adapter Having Issues with My Samsung 40" HDTV

So I ordered the brand new 15" i7 Macbook Pro along with the Apple wireless magic mouse and wireless keyboard after having bought my HDTV (went on a bit of a spree) with the intention of using the TV as a monitor for couch surfing. But, upon hooking up the adapter to the TV, my macbook's screen flickered between that blue transitionary screen and it's desktop screen. It did this for a few minutes. I jiggled the cable thinking that there was a loose connection somewhere as that was the problem with my previous mini DVI to VGA adapter from Apple. I did a little research and it turns out that they released a firmware update in 2009 for such a problem. I downloaded the update and attempted to install it but it did not determine that there was even an adapter connected. So, I proceeded to call Apple, they man was very calming to talk to and make all of my problems seem to melt away, but there were no solutions reached. He thought that maybe my TV either had a problem or was incompatible with the adapter (incompatible with a VGA connection? can you get any more analoge that that?). So, here I am, the adapter seems not to have a problem with regular monitors but I am still experiencing intermittent disconnects from my TV. I still, superstitiously jiggle the connection whenever I have dropouts but that really doesn't seem to be the issue here (or at least I hope not because that could mean port issues with my new laptop). Any suggestions? I noticed, after changing some settings on my TV, in an attempt to remedy this, that the TV was displaying the picture funny, I turned the TV off and then on again and it fixed the problem. That being said, perhaps I just need to turn my TV completely off when I'm not using it, as I have been just letting it go into standby. Maybe it needs a restart every so often much like my computer. I don't currently have data to support that theory as I just recently tried turning it off, but, since then have not had dropouts.

You may have the screen refresh rate set higher than the TV is generally able to track reliably. It may be able to get there most times, but occasionally loses sync because it is out of its nominal range.
I suggest you sit down with the manual for the TV and find out what resolutions at what refresh rates it intends to support through VGA, and make sure your screen settings are near (or below) those limits.

Macbook MiniVGA Display port Epson Projector Issues "Not Supported"

I have been using my Macbook OSx 10.8.5 with a Rocketfish Mini Displayport to VGA adapter (RF-AP307) connected to an Epson Projector (Powerlite83plus) for 3 weeks and just the other day a blue screen appeared on the projector stating that the computer is 'Not Supported'.
Actions I have already tried:
- turned on and off mirroring
- changed the refresh rate
- unplugged VGA adapter and restarted the computer
- attempted to install firmware update for MiniVGA display port following directions located here: http://support.apple.com/downloads/_Mini_DisplayPort_to_VGA_Firmware_Update (update failed because VGA adapter not found)
Anyone having similar issues and have some additional solutions? Need a solution fast, if I need to buy another VGA adapter I will but would rather not have to spend the money again...
Thanks

"- attempted to install firmware update for MiniVGA display port following directions located here: http://support.apple.com/downloads/_Mini_DisplayPort_to_VGA_Firmware_Update (update failed because VGA adapter not found)"
That update is for the Apple branded adapter, not the Rocketfish adapter.
I have the same adapter as you and have had no problems. That doesn't really mean anything other than the part does work with many types of projectors. Yours could have failed, though. Does it work on any other display or projector?

MBP 15' 2011 Mini display port to LED monitor/TV resolution issue

Hello,
I have just bought a Mini Display - VGA adaptor which I am plugging to a Samsung 23' LED monitor via a VGA/DVI adaptor. I manage to get a clone view but unfortunately, the maximum resolution offered is 1650x1050 when my Samsung LED monitor has resolution of 1920x1080. Therefore, part of the screen remains black.
... also, when I plug the Mini display port to VGA to my Philips 47' VGA port, I got a message that there must be a problem with the connection and again, maximum resolution offered if 1440x10.. and therefore 20% of my TV screen space remains black.
At last, when I launch Windows7 via bootcamp, this is even wost : when I select the max resolution (1440x10..), the pictures remains freezed on my TV and I can't even move the mouse (while the mouse is moving on the MBP screen...). Only coming back to a very small resolution 800x600 or so will enable me to get control of the win7 desktop on my TV...
Thank you in advance for your help
Greg

If you are using the monitor in Mirrored mode, its resolution setting will always be exactly the same as that of the built-in display. I presume you have the high-res 15" MBP display, with a native resolution of 1680 x 1050. If that's true, I suspect your monitor is indeed in Mirrored mode, and that's why you can't set the monitor to its native 1920 x 1080 resolution. If you press Command+F1 to toggle the mnitor into Extended Desktop mode, you'll be able to set its resolution independently of the built-in display. Or if you use only the external monitor, with the MBP display closed, you'll be able to set the monitor's resolution to whatever it supports.

Stacking one video adapter on top of another is usually a recipe for trouble. It's always best to keep things as simple as possible. Use one adapter that gets you from mini-Displayport to whatever input you want to use on the TV or monitor.

Mini Display Port to VGA Adapter Resolution Issue

Hi there folks, I just had to replace my NVIDIA 8800 so I opted for the upgrade to the ATI Radeon HD 5770 (Apple part number: MC742ZM/A)
I have two monitors on my desk, an apple 30" cinima display and a smaller 19" Hyundai monitor that uses a VGA connection as my second display.
After hooking up my Cinima Display to the DVI, and the Hyundai to the Mini Display Port via adapter and restarting my Mac the second monitor does not show up. Well, It appears on the arangement screen, and on the system profile screen, but no image appears.
If I unpluged and replugged the monitor then I can get an image to appear. Only I cannot change the resolution from 800x600. The monitor supports 1900x1200. I can see the correct resolution in the list, however selecting that resolution will not stay. It always reverts back to 800x600. I tried several other lower resolutions and none of those work either.
I zaped the PRAM, checked for system updates, hopped on one leg and cursed the gods but nothing has worked so far. I can give tech support a call tomorrow, but I was hoping someone on the forum knows of a solution since I know many of you are smarter than the tech support folks.
Thanks in advance!

I had the exact same problem. It actually escalated from there and it would crash at the startup screen (the white one with the apple and the spinning gear). The only way I was able to fix this was to reformat the entire computer. I was lucky enough to have backed up all my data when it first started crashing. I've only reformatted yesterday and things seem fine for now. I don't know what caused it, or how to fix the problem any other way.

P2415Q - No display over DVI, HDMI. No menu. Worked perfectly for one month over display port

Reason Line: Dell P2415Q. After one month working perfectly over display port, no display on screen over Display Port or HDMI, no response to menu buttons, backlight and power LED on but no image on screen.
Problem Description
The monitor worked out of the box for one month using the display port to mini display port cable provided with the monitor, which was plugged into my XFX 7970 and 7950 graphics cards. It supported 4K at 60Hz and was exceptional for photos, videos and games. On Wednesday the monitor stopped working, no image or menu is displayed on the monitor. I plugged in my old monitor to help diagnose via DVI from the same graphics card. When I press the power button on the Dell P2415Q monitor, the power LED lights up and the computer detects the monitor (as shown in the windows screen resolution menu). It sets it as a secondary display but the monitor remains black, I can see the power LED and backlight is on. No power saving mode popup appears on the monitor, when I press the menu buttons there is no response from the screen, it remains black. I repeated with a HDMI cable the same issue occurs with no response or image. I repeated and disabled crossfire (which allows the graphics cards to function independently) and tried the second graphics card with no response. I tested the HDMI cable I used on my old LG monitor, it works well. I have tried connecting a laptop over HDMI to the monitor too, with no response from the monitor. I have exhausted all the tests I can think of, I presume I will have to return the monitor for repair or replacement under warranty. A question to the dell rep and community - is there anything else I can try / do to get it working?

Mini display port to HDMI...help

I have all my options selected and was just about ready to click purchase on a new 2010 17" MBP and thought I would double check one more thing...Mini display port to HDMI with audio.
I see many post about this, but most seem to be on 08 models...have the new ones changed? I am more less getting this for my wife to use and she needs it for presentations. I finally got her to go from PC to my old 17" G4 laptop and it's time for an upgrade. The one issue we run into is that files are commonly sent as Power Point, but we got through that with a Mac/Microsoft upgrade.
I am told the location that these presentations are displayed, plans to get a new monitor and they are looking at BestBuy and such for TV style monitors with the HDMI option. This seems like a cheap way to get away from the projector system they have now that only supports S-video or VGA. I'm hoping that Apple now supplies audio thru the HDMI cable which is in my (limited) understanding the main reason the change over from DVI to HDMI was implemented in the first place.
If the no audio issue is still a factor, maybe I should put off the new MBP, because I am trying to get away from having to make the trip with her, in order to make sure we have both audio/video. With the projector system they now run, I have to take a PA and output the audio from the headphone jack and then run the S-video to the projector. I am hoping the new MBP will have one cable connection and she be on her way!

Well for starters, anyone who puts audio into a PPT presentation needs to be taken out back, beaten, drawn and quartered, beaten again, put in a stockade, flogged, then beaten one final time for good measure. The only audio coming from a presentation should be the presenter speaking. The PPT slides are meant to be secondary in nature, highlighting the major points of the presentation as you go along, not be the presentation. Audio and video, even those stupid transition effects, just distract from the content. The people at Microsoft responsible for putting those features into PowerPoint, and thus opening the floodgates for all their competitors, should have all the above happen to them, and then add being shot to the very end of it. It's still far too good a fate for the **** those people have loosed unto the world.
That being said, I'm under no illusion that this is going to do anything but get worse over time, so here's the deal.
You need a MDP to HDMI adapter that is designed to also carry the audio signal. But it couldn't hurt to teach her how to ensure that the audio output device is set properly. Just in case. Or, you could do the right thing, and start smacking the people who think it's cute to put all these animations and sound effects into presentations. There are a very select few times when that sort of thing is justified, and 99.99999999999999999999999999999% of the time when one is used, it's not one of those times. Then you wouldn't really have to worry about getting audio AND video. Might be rather cathartic too.

Mini-display port to hdmi cable not working consistently

I have a MacBook Pro (15-inch, Early 2011) 2GHz Intel Core i7, 4GB, Intel/ATI combo video - Yosemite 10.10.2. I purchased the monoprice 15" mini-display port to hdmi cable and it worked perfectly for about 1 month or 2. Now when i plug in the cable, the MBP doesn't detect that I have a second display connected at all. I assumed the cable died so I tested it on my iMac. The cable worked. Also when I try my Monoprice 15" mini-displayport to VGA cable, that works on my MacBook Pro. I can't figure out what is causing my MacBook Pro to "forget" how to detect this cable. Anyone out there experiencing the same? I tried PRAM reset to no avail. Any suggestions would be great.

Mini display port to HDMI problem...still happening, apple needs to help!

i read a lot about this topic and the question was marked answered, but there was no answer, sooo...
this is just a heads up to apple that this problem still exists and many people are still having it! Please do something... you put this mini display port on your computers... sold them to us... and now dont have software that lets it work... loosing a lil faith in apple today! there were 11 pages on this that i saw, i think it deserves a firmware update!
this next part is a direct copy of a post by sanktcolon and he explained the problem very well, so if your interested...
I figured I would just tell you all about my story. I do not have any solutions, the problem is still ongoing. But first I'd like to clear some confusion.
There seem to be a couple of people in this thread who thinks that when you experience this problem and you plug the HDTV with your MacBook through HDMI, you get a connection with the HDTV and can change the settings. This is not true. What happens is that the MacBook will flash its screen like it does when it detects a TV being connected, but then it will go back to normal. No connection established. Of course, there's people in this thread with different kinds of problems but with similarities. However, the main problem in this thread is quite clear and it's the same one that I have.
So with that out of the way, here's what happens for me and most people in this thread:
I've been using a Mini Display Port to HDMI adapter for quite a while and it has been working great. But lately I've been experiencing issues with it. There is nothing wrong with the adapter nor the cable, and certainly not the TV.
When I connect the adapter to the computer, the screen on the MacBook will flash blue, like it should, but it will not connect to the TV. What does this mean? It means that it detects the TV but is unable to establish a connection with it. Probably because it sends the wrong signals.
Now that's all pretty logical, but here comes the weird stuff. If I continue to try and re-establish a connection, either by plugging in and out the cable or changing HDMI-ports with the TV-remote (the MacBook re-detects when I switch from HDMI1 to HDMI2 and back), it will eventually establish a connection with the TV and work fine. Though, this can take minutes. Plenty of minutes. Last night I tried re-detecting for about 15 minutes and it didn't work. However, this morning it worked quite quickly.
So the problem is quite obviously with the MacBook/the OS and not with the adapter, cable or the TV. It's just ridiculous, and frankly quite annoying, to read posts where people claim you should get a new adapter. Why? Because there's so many people out there with different adapters, and people who have switched adapters and so on and so forth, that experience the exact problem I just describe. So either there's a problem with the MacBook/OS or there's a lot of TVs and adapters out there that are faulty. It's just illogical.
Once again I would like to remind you all that there's no connection, what so ever, between the TV and the MacBook when it doesn't establish one. And by establish I mean that you can actually see the screen on the TV. So bringing up the display settings won't do anything, search for devices on the TV or in the MacBook won't do anything. There just is not a TV there for the MacBook.
I have tried everything posted in this thread and the only thing that works for me is trying over, and over, and over, and over again until it just randomly works.

I too am having this same problem with my Macbook Air (Late 2010 Edition). I think this has something to do with OSX 10.6.6. Before the update, my mini display to HDMI was working flawlessly. Now, when I try to plug in to the TV my macbook just flashes the blue screen with no picture going to the TV what so ever. I'm not sure what was done with the update, but i'd sure like to be able to connect this machine to the TV again! APPLE, HEAR OUR VOICES! Fix this problem!

Mini Display Port To HDMI Cable Not Working?

Dear members,
i have a mid 2010 13" macbook pro which i have been using a mini display port to HDMI cable which also carries audio for for years now.
I went to use it last night and have to pull the cable out and plug it in a few times to get it to work.
Tonight it just wont work at all no matter how many times i pull the cable out and plug it in again!
Before i use to just connect it and boom, screen would go off then on and it would also mirror on to my TV.
My TV is a 32" Toshiba TV, i tested the HDMI ports, working fine. The mini display port to HDMI cable works fine on my 42" TV downstairs.
Any one know of a fix for this?
Thanks.

Thunderbolt mini display port cable to HDMI not registering

I recently purchased a 6" mini display port to HDMI Cable. When I connected my macbook to my HDMI on my TV the macbook pro does not show the screen as a display option. When I go to system prefrences and under displays the tv is not showing up under arrangements. The only options I have is Display and color, I do not have an arrangement option. My TV doesn't seem to see the computer either.
I have a thunderbolt port but the cable says it's for a mini display port but works with Thunderbolt, I've used similar mini display cables before with the thunderbolt with no issues. I'm on an early 2011 macbook pro running 10.6.8
Thanks!

You may have better luck getting a response/answer if you post the question in the MacBook Pro discussion here.

Mini display port to VGA not showing correctly on TV

I have a new 2012 (June) MacBookPro running 10.7.4 with a 2.5 GHz Intel i5 processor. Graphics Intel HD Graphics 4000 512 MB.
I'm trying to connect a Toshiba flat screen TV to the computer via a mini display port to VGA adapter purchased from Apple with the computer. Sometimes I see 5 lines running down the screen. I can get the screen to show on the TV by changing resolutions and refresh rates (1280 x 768 at 60Hz) but the TV shows 5 partial screens on my laptop screen (between those different vertical lines). I feel like I'm looking at the beginnings of an abstract art piece.
All software is up to date.
Any advice would be appreciated.

Called Apple Support and they solved my issue.
1) Restart the computer in Safe Mode with display attached (shut down and restart while holding down shift key).
The display showed up without distortion.
2) Change the display to my desired preferences (dimensions and refresh rate).
3) Restart computer. ...and it works like a charm.
Vioala!
