Mini display problems

I have an old G4 mini I want to use again. If I connect the mini to my LCD via a vga cable and the mac dvi to vga adapter all is well. If I connect with a dvi to vga cable I get nothing (the cable is called a DVI-D single ling/HD15 Male). Any ideas why the cable does not work?

Can you possibly post a manufacturer's link to the cable you describe? DVI-D to VGA doesn't make much sense since one is digital and the other is analog. It seems the correct cable would be a DVI-A to VGA. Since the DVI port on the mini is DVI-I, meaning it is capable of carrying either digital or analog video, a DVI-A cable would properly pick up the analog pins of the mini's DVI-I connector.

SONY answers for mini display problems

I have successfully hooked up my SONY KD-34XBR960 via the HDMI input to work with my new Mac mini. Most of the explanations in the forum about how to do this were incomplete, and lacking a final (albeit obvious) step. I followed the directions listed here: http://tenant.com/mini.php
We used a DVI to HDMI conversion cable and DisplayConfigX. After setting the new display parameters with DisplayConfigX, you still need to change to that display setting in the OS. Then you'll get a picture. You can play with settings a bit and will probably have to adjust for overscan, but it works very well, and the picture is amazing. Text is very readable, and the digital video playback is as good as my high end dvd player. I am glad we have this forum to talk about solutions to tech problems, Apple's tech support people couldn't have been less helpful or more clueless.

The resolution of my Sony with the Mac is 1192x680 which is 720p according to Michael and Jim at http://tenant.com/mini.php.
I am very happy with the Sony Wega 60XS955. The image quality is pretty good on analog and excellent on digital/HD. The mac mini looks absolutely fantastic on it as well. It's perfect!
The DisplayConfigX application is easy to use. You have to purchase a serial number to use the advance DisplayConfigX features. It is required when configuring the resolution for the XS955. It costs $12 to register it and the serial number is emailed immediately.
Setting it up can be a little awkward. You have to install a VNC server on the mini and use another pc or mac to remotely connect to it. The VNC is very simple to use and so is connecting to it. Then you configure the resolution, install it, and then set it. That's really all.
Yes. I had to reboot a couple of times to get it up and running. Once your done, that's it.
If you need any help, you can email me @ [email protected] or vist the http://tenant.com/mini.php. If it wasn't for Michael and Jim from that website, this would not be working.
FYI... I did test the mini on a top of the line Samsung and it looked incredible. But I chose the Sony because I watch more TV than I do surfing the internet. It was more important to me to have a better television image than a computer image.
Good luck!

Mac mini display problems

My Mac mini (bought in early 2011) has recently started having sync problems with my viewsonic monitor. It used to work fine. Have upgraded to mountain lion and mavericks hoping to solve the problem but it persists. I get snow and then blank screen. This happens randomly I never know when the screen is going to go white on me.

What connection configuration are you using...?
HDMI to HDMI
HDMI to DVI
Mini DisplayPort to HDMI
Mini DisplayPort to DVI
Mini DisplayPort to VGA
Have to tried resetting the NVRAM...? see > About NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.

Please help me! - really weird mac mini display problem.

Ok this is just too WEIRD.
i have a brand new 1.42ghz mini (512mb ram and wireless) with a sony SDM-HS75 LCD. This is an analogue LCD and im using the supplied apple VGA adaptor.
before i continue i will say that i have hooked up the lcd to numerous other macs and the screen and cable are fine. i have no dimmer switches on my lighting, i have no objects placed on the mini (like a cell phone etc)
when i first set up my mini the video output was murky and grey and noisy across the screen. Then i discovered the setup utility on the CD that came with the sony screen. i ran it (it displays a grid calibration thing) and discovered the "phase" adjustment on the sony's on screen menu. i managed to adjust out the fuziness and noise and the image quality was then perfect.
heres where it gets weird. the point at which the monitor is in phase with the video signal shifts around all the time! i mean - i get the phase set at say 43 out of 100 on the adjustment scale and the next time i restart i need to shift it to 73 to get rid of the blur and the noise on the display.
Also, the using airport affects the display and knocks it out of phase - i dont use wireless but if i activate it i can see a difference instantly.
this is really strange and i cant see a solution.

Is this a new-ish LCD? Many newer LCDs will have an auto adjust option or button to set the phase and fine tuning for you so you don't have to do it yourself.

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!

HDMI to Mini Display Port problem.

When I connect my MacBook Pro 13" (early 2011) to my TV using my HDMI to Mini Display Port adapter the MacBook just shuts off completely. I can use a VGA adapter no problem but I would like to get better picture quality from HDMI. Anybody have any ideas what the problem is?
Thanks in advance.

Have you tried a different adapter/cable? This is where I would start. (see if you can borrow some).
You can also try these resets:

SMC:

These are start points, gotta start somewhere, right?

Problem with HDMI to mini display port

I have been using the HDMI adapter to mini-display port successfully with my TV for months. I have a late 2011 Macbook Pro. My brother borrowed the cable to use with my mom's 2013 Macbook Pro retina display and now the adapter won't work. He could not get it to work with her Macbook and had not realised that it had HDMI input so used that instead. Now he returned the adpater to me and it does not work! I am running software version OS X 10.9.2. I read about a lot of problems similar but they seem to relate to 10.8.2 software. Can anyone help or advise me why my adapter has given

I have two adapters and both have stopped working after using them with the later (2013) Mac. I think it may have damaged them in some way!

Problem w/mini-display to DV I adapter, a Macbook Pro 13" & 30" Cinema Disp

I recently switched out my old 15" MacBook Pro for a new 13" version. My old MBPro had a DVI input and the connection between that machine and my 30" Studio Display was not a problem.
However, as I now have the 13" and need to use the mini-display adapter I am getting occasional screen flicker and worse, total static on the screen. It's like I'm in the 1950 watching a B&W TV with rabbit ears.
I have checked and rechecked all of the connectors, but this has become a daily battle to get a clear picture.
I know the display has some years on it, but it's been good till now and I'd like to hold on to it.

Make sure you have the latest version of the Mini DisplayPort to Dual-Link DVI adapter. Check via System Profiler (Utilities folder). It should be at least 1.0.2
<http://mjtsai.com/blog/2009/10/03/mini-displayport-to-dual-link-dvi-adapter-imp roved/>
It could also be a problem with USB power for the adapter. If you have a charger for iPhones or iPods that use USB, try using it to power the adapter (plug the display's USB cable into the computer).

Mini display to hdmi adapter problem

Hi,
When I connected my mini display to hdmi adapter to hdmi, and hdmi cable to my ASUS PA238QR monitor, my early 2011 MBP 13" detects the monitor, but the monitor shows "hdmi no signal".
I tried unplugging everything, including the adapter and hdmi, but to no avail. I tried putting my computer to sleep, and waking it up, still, nothing seemed to be the cause of the problem.
I read through some old discussion on this issue, and nobody seems to have a solid solution besides purchasing another adapter.
I tried booting into win7 and still, the monitor shows "hdmi no signal".
I am 100% sure my monitor and hdmi works becuase when I used other laptops it's fine.
Thus, I'm suspecting it's the mini display to hdmi adapter's problem.
Is there a way I can make sure that my macbook pro is outputting the signal?
Any recommendation or advises are welcomed. Thanks for reading.

If you've an HDMI port on your television, you could always try that.
I've used this adapter from Monoprice successfully - not bad for under $7.
Give your TV a try - if no go, then you'll know that it's an adapter problem.
Good luck,
Clinton

Mini display port to DVI problems

Hello community,
I have a question regarding the connection from an iMac via the mini display port to a DVI input at a TFT monitor. I have an older TFT monitor and now I connected the iMac with this monitor via mini display port -> DVI adapter -> DVI cable -> monitor.
It is quite a simple connection, but actually when I force Mac OSX to detect external monitors it does not react at all. Mac OSX behaves as if there is no connection to an external monitor.
I already told this to my reseller and they told me that the adapter is not working correctly and they gave me another one. With that one I have exactly the same problem and now I'm quite sure, that it is not a problem of the adapter, but somehow my iMac does not find the external monitor.
Is there probably an underlying problem I do not understand yet?
By the way, my very old Macbook White has no problems detecting the monitor. If I use the older video output it works fine, but the new output at my iMac 21,5 inch does not work with my monitor.
My question is, why does it not work and what kind of monitor do I need, that it can be connected with my iMac (via DVI)?

Is the adapter plugged in all the way in the Mini DisplayPort? It takes more force than you might expect.

IPod mini 1st Gen. Display problem

Hello everybody!
I've got a problem with my iPod mini display: In the last few weeks the display got brighter and brighter.. or should I say I lost the contrast? .. so now I can't see anything on the display. The iPod works very well but I have to use it blind And the problem ist not solved by using the contrast settings! But now I can't see the seetings anyway I think, the display is internally damaged or something like this..? Do you have any idea? Thank you very much for your help!

Problem with mac pro 2x2.93 GHZ Dual Core and Mini Display Port

Finally I see the button to create new post!
I would like to explain a problem I have with my mac pro 2x2.93 GHZ Dual Core Intel Xeon processors and the ATI Radeon HD 4870.
I have two 30 "Apple. After buying the new Mac Pro is one of the two monitors, only with the monitor all black, small horizontal lines.
This happens only to the monitor connected to the mini display port... So if you reverse it monitors the problem always moves on the board connected to the Mini Display Port.
Apple has already changed my video card and the adapter but the problem is still there.
Someone can tell me if it is the ATI Radeon HD 4870 that has problems to have two monitors 30 "? Or it could be that the mini display port that is hard to read the two monitors and when the background is black (RGB-255-255-255) makes these lines?
Through the Apple store I then bought a new card (EVGA GeForce GTX 285 "). Unfortunately, after three weeks of waiting is not yet arrived. Proof that I want to do before returning to telephone assistance is whether on a card that has two dual-link DVI ports normal all goes well.
Sorry for the repetition of messages, but my English is very bad. This is the first time I connect to this site support

In any case, this system does not support two 30".
I honestly don't think the 4870 with that adapter can support two 30". Just using the adapter itself would not give me the normal resolutions on my 30, where as the DVI port did. Luckily for me the adapter worked fine on my 20".
Truly I don't know why Apple would sell a card and not say just what displays it can power.
So I worked around my problem fine but I chose to get the 285 also. My question to you though is, did Apple make you pay for it? Was it part of a deal with them because the Radeon didn't work? You might want to talk to them about that. That is one expensive card.

Mini Display Port to HDMI sound problem

I have an iMac 11, 2 (MacOS X, 10.6.8). The Mini Display Port is supposed to be able to carry sound, (using a Monoprice Mini DisplayPort to HDMI Converter with Audio, and HDMI cord supporting 3D, and Audio Return.) I am playing downloaded movies with VLC, which works fine on the computer. When I try to burn DVD disc using Toast Titanium, I get video, but no sound. So, I figure I can watch movies on my Vizio 42" TV screen with the MiniDisplayPort to HDMI cord. I learned that to use the MiniDisplayPort I have to go to click the box for Mirror Display. In System Preferences--- Sound---- Output Tab, the only two choices are: Headphones...... Headphone Port, and E3D420VX....... HDMI, neither of which seem to help "push" sound through the MiniDisplayPort.
So, I give up and watch the movie on the Vizio screen (through the HDMI cord), while listening to sound on the little computer speakers. After watching a couple of movies, and then not doing anything for a few minutes, all of a sudden the movie starts replaying off the play list, and lo and behold..... sound coming through the TV speaker system!!! (So, I know the HDMI cable is capable of carrying audio.)
If any one can help me figure out how to get sound through the HDMI cord all the time, it would be greatly appreciated!

Hello,
Long shot, but...
Open Audio Midi Setup in Applications>Utilities, see the input & output options & KHz setting there, some things will change it for their own use, then not set it back.

HP Pavilion 27xi Monitor: Display problem Mac Mini running Yosmite

Image quality is very poor for Mac Mini running Yosmite connected via HDMI.
Adjusting overscan helps scaling, but pixelation and poor image quality is not changed (very blurry)
Using VGA/mini display route with same devices, image quality if far better showing that somehow mini conncected to HP monitor via HDMI could be improved via driver update.
Is there a driver update for Yosmite?

Hello @adsben,
I understand that the image quality for your HP monitor is poor when connected to your Mac Mini, and I would be happy to assist you in this matter!
According to this document on using HP Monitors on a Mac:
"HP monitors are not supported in a Mac environment. However, newer Macs use graphics with VESA modes and can display to most HP LCD monitors. To do this, connect the monitor to the Mac while the Mac is off, and then turn on the MAC. The monitor should operate at 60Hz. The INF and software for the HP monitor are for Microsoft Windows and cannot be run in a standard MAC OS environment."
I hope this helps!

Mini Display Port behaving badly. Anyone else have this problem?

I have had an ongoing issue with a mini display to VGA adapter, every time I plug it in it becomes erratic over the course of use. It will lose signal and send the monitor blank if I go to remove any of the usb peripherals in the back of the unit. I have returned the unit to Apple 2x now and they have replaced the logic board 2x and the mini display to VGA adapter, yet this is still happening.
I have tried it with different monitors and cables etc, but this is still going on.
Is a mini DVI to VGA any more reliable?
Has anyone else had this issue

Thanks for the suggestion , but after an extensive talk with tech support and running through the usual troubleshooting regime we came to the conclusion that the best thing for all concerned is that Apple send me a mini DVI-VGA adapter. I am cool with that. No matter what combination of adapters and cables and monitors I plugged the mini into I kept coming up with the same results and my local guys had the same thing happen.
Thanks anyway.
