Mac Mini :: Unable To Get Video Signal
Mar 16, 2009
I received my new mac mini last week and installed a few things on it over the weekend so that I can run it as an HTPC. Works great but I am having one issue and that is with the video signal. I have the mac mini connected to my Samsung 720p LCD TV with VGA using Apple's miniport to vga adaptor.
When the TV is already turned on and I start the mini or bring the mini out of sleep then everything works OK. However if the TV is off and I start the mini or bring it out of sleep and then turn on the TV, I get a "no video signal" message.

My mini "starts" without chime when I press the power button on the back. The fan starts, the light in front goes on and I hear some clicks which could be the hard drive. The screen remains black (no signal) and the mini does not respond to the USB keyboard power button. It does not start when pressing it and will not power down if I press it for any length of time when it is on. Pressing the power button on the back for some time shuts it down.Â

Just a warning, I bought a Mac Mini (2009) and wanted it to hook it up to my TV. My TV does not have HDMI or DVI inputs so I bought a Mini DVI to Video adapter from Apple.But I could not get it to work, then I googled for it and it seems this adapter does not work with 2009 Mac's since it does not output an analog signal anymore!

So anyone that wants to hook up his new Mac to an older TV set with the Video adapter, you are warned.I guess i'll have to buy a Mini-DVI to VGA adapter and then a VGA to SVIDEO converter..

My TV doesn't have DVI or VGA inputs, so I can only use component video input to plug my mac mini(mid 2007).
But I have serious problems with it. I have bought a Dvi to component video cable on eBay but it doesn't work with mac mini(it works with old PC).

I just recieved my Mini DP to DVI adapter so that I can use my second 23" Apple display. I just upgraded to ATI Radeon HD 5770 so now I have 1 DVI and 2 mini DP. I want to run 1 display off of the DVI and 1 off of the Mini DP. Both displays work with the DVI port but neither of them work on the Mini DP with the adapter.
I know that I need to upgrade to Snow Leopard for the ATI Radeon HD 5770 to fully function. I am waiting for the upgrade to arrive in the mail. Do I need to be running Snow Leopard for the Mini DisplayPorts to work at all or is there something I can fix before the upgrade?

I have a 2009 model of Mac Mini and I have a 32" Samsung TV as the primary display hooked up though MiniDVI converted to VGA and it works properly. But my second Sony 19" monitor hooked up though DisplayPort Converted to VGA does not receive signal. It is detected by Display but no signal is being sent to it. When I have only the monitor though the DisplayPort hooked up it doesn't receive signal but when I have one only though the MiniDVI it displays fine so I know its not the Monitors.

I have a Mac Mini, and recently I buy a television by Sony 3d (46"). For my surprise, the television don't accept the signal from Mac Mini. On the screen appears the message (Signal Incompatible). I change all configurations, but nothing. I call to Sony and they don't have idea about the problem.

I have MacMini and the display signal turns off intermittently (i.e. not just sleeping).Â
The display is via a VGA connection to a Philips monitor (although I've tried with an Acer VGA monitor too and get the same problem).Â
The only way to fix it seems to be to turn the Mac off and on again.Â
I feel pretty disappointed. I've used Apple Macs since having a Mac Plus 20 years ago and have always recommended people to use them because "you just plug things in and they work"...Â
But this is simply rubbish. It's practically useless. should I just try to get my money back under the "not fit for purpose" clause in the sale of goods act.

What a great place! I'm wondering if anyone has a solution to connecting a mini to the above TV.
I have the same TV in 32 inches and use a mini to HDMI cable that works perfectly. For some reason, the 40 inch TV says 'no signal' when I try to hook it up the same way. I've tried all the HDMI ports...including ones that work with other devices.

I just got a Mac Mini no too long ago and while moving to my new apartment, my wireless router had a tragic accident and is no longer with me. So I thought "hey, I will just use my Mac Mini to broadcast a wifi signal so my other devices can connect to it." So I spent the morning setting up the internet sharing in the Mac Mini system preferences. Got my Dell Studio 1555 to connect with no issues. But my roommates acer notebook won't pick up the wifi signal at all. Checked it on both of our smart phones (both are android models), my nook, and even my ipod touch. It is only showing up on the dell for some reason. I was wondering if anyone else has encoutered this issue before Mac mini is currently set up with 128bit wep with a 13 character password.

I have 40 MacBooks in a small private High School. The High School is on a church campus. The school has 4 Airport Extreme's with an SSID of CCHS. On the same campus there are 2 other public WiFi networks. What I want to figure out without having to worry about blocking the Mac Addresses on 2 different routers everytime a new High School MacBook is being used it to setup on the MacBook so it won't connect to those WiFi signals. We use Apple Remote Desktop to monitor the MacBooks and sometimes the students are connected to other network and we can't see their laptops.
We have an Xserve server that all the MacBook's are bound to and can make changes to the MCX records but need to know what I can do in order to make it so they can't connect to these 2 other networks.

I have a March 2009 Mac Mini that was working fine under Leopard when sending out a signal from mini display port to hdmi and then to a Samsung HDTV. Now when I upgraded I get more options for monitoring HD signals but my TV signal drops out intermittently. I suspect this is a bug with Snow Leopard and HDMI. Anyone have any inklings on how to solve this issue?

After lots and lots of reading I went for flashed Sapphire 4870 512 off eBay for my Mac Pro 1,1 running SL 10.6.2, with two Viewsonic VP2030b. The guy selling the card had sold flashed cards before and had 100% feedback, said the card worked with dual monitors and supported SL. Got the card, installed it without a problem, but could not get it to work with both monitors.
Second monitor said no signal on both DVI channels. Checked all the wires, reinstalled, rebooted, no luck. Plugged both into my 7300GT, no issues at all. At one point, I got the left monitor to boot as the extended desktop, showing the dock but not showing the HDD or icons (which should be on the right screen), but the right screen still showed no signal and was black. Used the gather windows botton in the display preferences to see if adjusting settings helped, still nothing. Detect displays button was no help either. Is this a compatibility problem on my end or a flashing problem on his? Contacted him and he said he had no issues with his MP 1,1 and two 20" Apple displays.

I've spent the past few hours attempting to connect my new Windows 8.1 laptop to my iMac's Airport signal without any success. Â I was able to do this very thing using Windows 7 on an old laptop. From what I've been reading, it seems that the ability to connect to networks secured with "WEP-Shared" type security has been removed in Windows 8 because of the fact that it was outdated and insecure. It's great that Microsoft is trying to force individuals to be secure, but unfortunately the iMac's airport utility does not offer any alternatives.

I have an Early 2009 Mac Mini with Mini DVI and Mini DisplayPort. And I have two 1080p HDTVs. The Mac Mini is capable of dual display, and I've gotten it to work before, so the issue is not the TV or Mac. And I have tried both Mirroring and No Mirroring.
I got a Mini DisplayPort to HDMI Adapter (#5311) and a Mini-DVI to HDMI Adapter (#4852) both from MonoPrice. And for some reason I can't get the Mac Mini to dual display, it's only one or the other.
Before I had a Mini Displayport Male and USB Male AUDIO to HDMI Female Converting Adapter (#5969) and I got video on both HDTVs, but not audio at the same time b/c one was USB and one was TOSLINK.
I'm not sure why I can't get video on both monitors. Any help?

Just bought the new mac mini with HDMI out - 2.66Ghz, 8 Gb RAM, 500 Gb HDD
A lot of mkv or avi files I playback appear pretty choppy in VLC - my primary app for watching movies and tv shows.
I have a Drobo with two 2 TB SATA drives where I store all my stuff and which is connected to my mini via firewire 800.
I've tried playing the same video back from both the Drobo and from the internal hard drive, to see if the choppiness was on account of the external drive or not. No difference really. A choppy video remains choppy from either place.
It's pretty strange because some 1080p videos play just fine, with no choppiness whatsoever, while other 720p videos or even standard definition divx files are still choppy.

So our church just purchased a nice refurb iMac to use for media presentations during weekly worship services. We have a projector with a VGA cable, so I bought a mini display port to VGA adapter from apple so that we can connect our shiny new iMac to our big screen.
However, when we attempt to connect our VGA to our adapter, they don't fit together properly. It's like the screws on the VGA cable aren't long enough to screw into the adapter...thus, the cable won't stay connected to the adapter (it just falls out).
Someone suggested getting an S cable to replace the VGA cable, but Apple tells me there's no adapter to link the S cable to the iMac. I'm absolutely clueless...surely there is a way to connect my wonderful new iMac to the big screen.
Any ideas?

I have a cheap hdtv. when i connect my macbook to it it doesn't get a signal (via mini dvi to hdmi) until i click "detect displays" on my laptop, then "gather windows," then when i set the display to the proper resolution (720) the image appears on my tv without a problem.
I just got a mac mini, and since i don't have two monitors I cannot use this trick. I get no image on my tv.

Okay I'm writing this for anyone who feels the same as I did about doing this and is unsure whether or not to do it. Maybe it can help someone
Last night I finally got round to upgrading my mac mini to 4GB of crucial memory using a 1.5" putty knife, mini screw driver set, pizza cutter, bright LED torch and towel. And boy was I pooooooping it during the whole process!
But don't let that put you off as if you do your research, take your time, double check everything you do, then double check again, have all the tools by your side and you are not a clumsy oath then you should complete it with out any problems.
My main concern is how much pressure you have to put on parts to remove them, compared to how easy they seem to come off on the vids I've watched. And how easy they seem to put the frame and memory in and out. As this is certainly not the case for a newbie!
The main outer casing for a start takes a lot of force and you are not quite sure how far down to put the putty knife. You think your going to damage the clips or case, but it seem really robust, you just have to trust it and do a little bit a a time working your way around the base.
The 2 small antennas seemed like they were going to snap on removal, really where attached well. One more than the other which caused me some stress
The bigger corner antenna, comes of okay, just don't squeeze the clips in to hard, as I did and managed to bend one in to much so when re-fiting I had to bend it out so it locked into place.
The next bit - the screws... make sure you have plenty of small screw drivers, all the ones I had were not small enough, so had to make a quick trip up to the DIY store half way through the job! The screws are impossible to get out unless you have a magnetic screwdriver, I could only get one out, left the other 3 un-done but still in the frame
The ribbon cable came of easy taking my time with a small screwdriver. After all this the whole frame came out giving me access to the ram - this took some jigging, be careful of the antenna wires and the ribbon.
Ram came out easy, but the 2 sticks I put in were not so easy. I could not see exactly where they had to go in, and took some force to get them in. Think it's all about getting the right angle though.
Everything went back pretty easy apart from the frame, this was a bit awkward getting it to fit exactly, but eventually it popped in to place.
I now have 4GB and intend to do the same process again when I can decide on what hard drive to buy to replace the 120GB internal + I am going to do my brothers.
Overall I am very happy I have saved my self money doing it myself, and learnt about the inside of a mac mini.

Im thinking of completing the mac transformation from work and laptop to my home computer, does anyone know, does the mac mini have a good enough graphics card to play HD video thats downloaded, my current PC's graphics card struggles.
I knowits due for revision so going to wait for that. Say the new mini has the same GPU as the current mac book, will that be enough?

I am using both video outputs on the back of the mini, VGA and HDMI. Thes VGA is running to a projector and the HDMI is running to a computer monitor. I am also running Bootcamp WINDOWS 7. When I power up the Mac, the computer monitor goes to sleep and defaults to the projector as the main monitor. If I power on the projector first, before powering the computer on and then power the MAC on, it recongnizes the computer monitor as the default monitor. Why can't the MAC mini recognize the computer monitor(HDMI) as the default when both video outputs are connected?

I recently have gotten into video, such as downloading .mkv files from Vuze, and .mov and .avi files from various other places. Now that I will be purchasing a Mac mini I hope to watch movies from the iTunes Store. One of the things I hated about my Power Mac G4 500 is that it's slow processor could only play about 45 percent of the videos I had. The rest of the videos I tried either the audio and video would either out of sync, just sputter along, or refuse to play at all. Will the 2.0Ghz processor of the new Mac minis be sufficient for video, or do I need to go with the 2.26 Ghz processor offered in the "build-to-order" option?

Can the new mini's with the new video cards run final cut pro? I am not a video editor but do some small projects once in awhile. I would max out the mini at 4GB of ram running (2) 24" monitors.
