Mac Mini :: Second Display Detected But No Signal
Jan 7, 2011
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 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.

I've been running a Benq G2400W on my MacBook Pro since December 2008 with no problems. I recently has my logic board replaced due to a power issue. I got the computer back a few weeks ago. For some odd reason, my monitor refuses to accept the signal from my MacBook Pro over DVI. I can use the DVI to Analog converter and it works just fine.
I did find a thread over at Apple Support Discussions outlining the exact issue I am having. The solution is to remove a pin from the DVI cable. I shouldn't have to destroy a cable to get this to work again. I might order a new cable/adapter from monoprice.com and destroy it if that is my only option though.
I just can't figure out what changed except for the logic board swap...but I don't remember if it has worked over DVI since I got it back.
I deleted the windowserver plist for my user and the system one with no change in behavior. Are there any other settings I could try resetting?
I've unplugged the Benq and reset the monitor via the OSD to default settings.
I did read over at anandtech that it could be HDCP related...but I'm not trying to watch a video.
I plugged the laptop into a Dell 1905 at work via DVI and it worked perfectly fine.

i m using LG22inch monitor, it is a vga cable connected to a dvi adapter connected to a dvi miniport.
initially i tried to plug it in without AC power, but ext monitor screen is black. I surfed the net for some solutions, it says tat the AC power must be plugged in for the external monitor to work.
However, when i plug in AC power, the ext monitor is still sleeping, even though i can detect it in my profile settings.. what can i do to wake it up?

I recently purchased an LG Flatron monitor to use as my second display for my MacBook Pro (unibody). I had it working with great results for about a week, but today when I plugged it in, the monitor is not detected. I have been looking through other's problems trying many of the same things, to no avail. [URL]

I have a MacBook Air and am trying via DVI cable to connect another display? The Mac will not detect the other screen. Any suggestions would be terrific. Do I need to "install" the old screen?

I have a Hanns-G 22in monitor that I'm trying to connect to my new Macbook Pro. There's a DVI cable connected from the monitor to the macbook pro with a little converter cable. I've tried what seems like every iteration of sleeping, turning off, and turning on both the laptop and the monitor to no avail. The monitor always remains black as if it's connected to nothing. I know the monitor is good, too, as I use it for my PC on a daily basis.

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 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.

I'm looking to run video out to two TVs, but it's over a decent distance, so I'm worried that using an HDMI splitter would cut the signal and suffer quality loss. I was wondering if both mini DisplayPorts can be linked to output the same signal at the same time, so that both TVs can show the same thing but each signal is at full force.Â

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

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.

So I have a late 2009 Mac Mini hooked up to my Kuro via the mini-DVI to DVI adapter then DVI/HDMI cable to my receiver. I get digital audio out of the Mini via another cable. First question, if I were to use a mini-display port to HDMI adapter would I get both sound & video?
I love using PLEX but my Mac Mini is my only "computer" (I have an iPad). I would like to sit at my desk and use photoshop and other tools. Second question, can I do dual display using the mini-DVI and mini-Display Port jacks at the same time on a Late 2009 Mac Mini?
My gadget loving self has purchased a HP Wireless TV Connect. I was planning to use the dual HDMI output of receiver but I couldn't work on the PC and have someone watch PLEX so that is why I ask about dual screen (essentially extended desktop) using those two ports. The plan is to use a mini-display port to HDMI adapter and connect it to the transmitter of the HP Wireless TV connect and then an Apple display to the receiver. Make the main display the Apple display and the extending desktop running PLEX on that screen the Kuro.

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.

The screen of my MBP 13 was shattered over the weekend, so I'm rigging up an external screen to tide me until I can fix the glass/LCD at the end of term. I have purchased an Acer P196HQL display and the MBP recognizes it, but the external display says 'No Signal'. I went to the shop in town where I was given a Thunderbolt/Mini to DVI-D convertor which then has a DVI-D to VGA convertor to connect to the external's VGA port. My MBP has Intel HD 3000 Graphics 384 MB graphics and is a GPU type, if that's relevant. I'd love to be able to revise for exams off of this laptop.

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?

I need to connect my 09' Mac Mini to my Yamaha RX-V2700 receiver which outputs to my Sony XBR HDTV. I know the mini has both mini-dvi to dvi and mini-dp to dvi or hdmi available via adapters. I was thinking to go with option 1 however I was wondering what is your opinions? Is mini-display port better over mini-dvi or are they the same? Audio will be carried over optical toslink.
Option 1:
Using mini-dvi adapter to dvi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.
Option 2:
Using mini-dp adapter to dvi or hdmi: Connect Dvi-Hdmi cable to receiver and output audio with toslink adapter.

I'm getting a high resolution, and it looks alright, but it's not fully using the widescreen. That's "aspect" right? Well anyway, I also have a 19" display and it works perfectly. My Xbox, cable box and movies all use the full widescreen on the Acer, but the Macbook with the super amazing Mini DisplayPort doesn't even use the full resolution. What's with that? I thought the reason they had this new port and a $30 adapter was for higher resolutions!

I hooked up my macbook pro to a mini display port to a dvi -> hdmi to my tv no problem. However, when I hooked up the mini display -> dell monitor, I get nothing. The screen is black. The weird thing is that my macbook pro recognizes that a second monitor is plugged in... it just won't display anything

I want to buy the 27" iMac - but only if I can use it as external monitor for my Lenovo laptop when working from home. A the Apple store in London they said that this is possible with a Belkin converter from hdmi to mini display port (with a USB power caple to turn it into an active signal). The laptop also has a displayport.

I have a mid-late 2008 MacBook connected to a Dell U2211H monitor using a Mini DisplayPort -> VGA connection.
When I use 1920x1080, I only get 60 Hz and the display is a fuzzy (text). Also, there are black bars. Why?
Will my issues be solved using a Mini DisplayPort -> DVI connection? Or should I exchange it for the 2209?

i have a 15 inch apple studio display which has ADC (was partnered with the cube) and I purchased a DVI adaptor so it now works fine with the DVI port on the macbook pro. I am considering a new mac notebook (not sure which yet) but as these have the new mini display port, is there an adaptor that would slot into the DVI end of my current one, so it would work with the new macbook?
