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?
Only drivers found were for Windows:

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!

Display Problem: Mac Mini no longer shows up on my Hitachi TV

Everything had worked just fine for a couple of months and then I started importing a bunch of my CDs. During this process, I did something that made the desktop image from the mac mini larger than that of the TV (So I couldnt see the upper menu and the lower one was partly cut off.
To try to fix it, I went into the display preferences menu and chose a different resolution (I think was something X something interlaced). When I did that, the screen faded black and I couldnt see anything. For a while, I could see the initial load screen for the mini, but the desktop would never show up and my TV would just say No Sync. Signal.
Any thoughts? Thanks a ton for your help.

hermanherman, welcome to Apple Discussions. Generally when this type of issue crops up it can be corrected by starting up in Safe Mode. To start the mini in Safe Mode, after pressing the mini's power button, immediately press and hold down the Shift key on the keyboard until you see a message on the display that Mac OS is starting in Safe Mode. When you see that message you can let go of the Shift key. Hopefully you will have a useable screen at that point. Go into Displays preferences and select your desired resolution. Then restart the mini normally (don't hold Shift) and hopefully your last resolution setting will persist and you will have your screen back.
By the way, what you were looking for in the first place is an "Overscan" check box within Displays preferences. This controls whether the edges of the Mac desktop will be beyond the borders of the screen or not. Good luck.

How to connect a 23" Cinema display and mac mini to an AV Receiver?

I am trying to get my 23" Cinema display and Mac Mini to a Yamaha RX-2700 AV Receiver. I am on first name terms with the guy in Maplins because I tried to get an Xbox 360 working with this display before and gave up in the end. The AV receiver has upscaling capability so I thought I'd try again. I tried connecting a HDMI - DVI adapter to the HDMI Out on the receiver and a HMDI to DVI cable from the Mac Mini to the HDMI in with a optical cable for the sound. The sound works fine but I get no display - the LED on the monitor flashes three times with a blank screen so it can't read the signal. Another option suggested was to use a VGA Converter connected to a VGA - HDMI cable but I would like to find out if that would work before going down that route?
I am looking for some advice about whether this type of configuation is possible with the 23" ACD and if so what do I need to buy to make it work? I love the quality of my ACD to avoid having to replace it with a TV to get my multi media life in order.
Many thanks

it started before my last update and hasnt been resolved after getting OS X 10.8.5
it shows on the WIFI sign WI FI: NO HARDWARE INSTALLED.
can you help me?

Test after taking each of the following steps that you haven't already taken. Back up all data before making any changes.
1. If you can connect to the Internet via Ethernet, Bluetooth, or a USB network device, make sure all available OS X updates are installed. If Wi-Fi is your only means of network access, skip this step.
2. Reset the NVRAM.
3. Reset the System Management Controller.
4. Boot into Recovery. In the menu bar of the OS X Utilities screen, there's a Wi-Fi menu. If it works, select Install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
5. Take the machine to an authorized service center for testing.

Out of Frequency Problem with Apple Multiple Scan 720 Display and Mac mini

If a resolution with a horizontal and/or vertical frequency not compatible with your display, in this case an Apple Multiple Scan 720 Display, is selected in the Display preference pane of the Mac OS X 10.4.10 system running on a Mac mini (Early '06), you will recieve a message on your screen about being "out of frequency" and the power management feature will shut down and restart your display repeatedly. The following solution should restore your display to proper function. It may apply to other displays and Macintoshes running Mac OS X, but it has only been tested specially on this setup.
1. Shut down the Mac mini with the power button (press and hold for 5 seconds)
2. Start the computer up with the Mac mini Mac OS X Install Disc 1 (press the power button, insert the disc, hold the C key down until the progress bar starts up)
3. Click on the language, then select Utilities > Terminal...
4. Type "cd /" and return
5. Type "cd Volumes" and return
6. Type "cd your hard drive name" and return (you need to enclose the hard drive name in double quotes if more than one word)
7. Type "cd Library" and return
8. Type "cd Preferences" and return
9. Type "rm com.apple.windowserver.plist" and return
10. Type "exit" and return
11. Quit Terminal
12. Select Utilities > Startup Disc...
13. Select the OS on the hard drive and click on Restart button, holding down the Shift key until the progress bar starts.
14. Log in to the account that had the display problem in Safe Boot mode
15. In System Preferences select Display, select a resolution with the appropriate frequency, 60 Hz should be fine, then close System Preferences
16. Restart the computer, log in to the account normally, and the display should be functioning properly.
DO NOT SELECT AN INAPPROPRIATE RESOLUTION/FREQUENCY FOR YOUR DISPLAY IN THE DISPLAY PREFERENCE PANE! BE AFRAID, BE VERY AFRAID!
Mac mini (Early '06) Mac OS X (10.4.10) Apple Multiple Scan 720 Display
Mac mini (Early '06) Mac OS X (10.4.10) Apple Multiple Scan 720 Display

Just a correction and an elaboration:
It should be Startup Disk... with a k, not a c.
Both the resolution and the frequency must be appropriate for your display to work properly. Check your documentation or the manual information available on your display for the appropriate resolutions/frequencies. Evidently the Apple Multiple Scan 720 Display is considered so old that no allowance was made for it in the Display preference pane of Mac OS X 10.4.10.

Mac Mini 2013 stuck on apple logo

My Mac Mini is stuck on the apple logo with the spinner underneath it. I was running a program and put the computer to sleep. When I started it back up, the program was stuck. I couldn't get to the command options and shut it down. When it started back up, I typed in my password, but it continuously got stuck on all my account logins. I tried to safe boot it, but it just loads the progress bar and goes back to the logo and spinner, even if I leave it alone for half an hour. I tried to use the option button, but none of the options work. I tried unplugging everything but the monitor and turned off my Apple Bluetooth mouse. Still didn't work. It is a 2013 model, so it has no CD drive. PLEASE HELP! I need this working soon. If it is possible to migrate another Mac to fix it or migrate one onto the disk after I erase it, please let me know. If not, give me some advise. I need help ASAP. Thanks for your help!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
     a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

Functioning Monitor will not display with Mac Mini

I'm trying to get an IBM E74 CRT monitor working with an early 2009 Mac Mini. I have it connected with Apple's mini-DVI to VGA adapater. The Mac "sees" the monitor since with screen sharing I can see the Display System Preference when the monitor is attached. It shows the monitor as an IBM E74 and allows what appear to be appropriate choices as far as resolution and refresh rate are concerned. I tried many combinations of resolution and refresh rate with no difference in behavior.
The monitor always acts like no signal is detected (built it message on monitor display). This monitor works fine with a B&W G3 and a late 2007 MacBook Pro. Any ideas why the Mac Mini is not driving the monitor? Have tried all combinations cycling power on the monitor, connecting / disconnecting while the Mac Mini is power up. Have had the monitor connected and powered on when booting the Mac Mini. For whatever reason the monitor does not seem to work with the Mac Mini, but works fine with other computers.
The monitor despite its' age has pretty low time on it and is quite serviceable. Are there quirks with the VGA interface that we may be running into? I would like to get this combo working together if at all possible.

I would say the VGA interface did evolve somewhat over that time period. In particular, the thing that may have changed that could be the underlying cause of the problem is sync termination impedance has trended upwards. It's not unusual to find older monitors with low impedance on sync. Some even had 75 ohm impedance, which required a line driver for sync the same as for video.
It could be the IBM monitor has fairly low termination impedance and the mini is unable to provide sufficient output on the sync lines to drive TTL levels, whereas the MBP is doing better. You could check this with a simple ohm meter with the IBM monitor turned off. Ideally, for the mini, you would want to see a high impedance reading on H and V sync, like close to 2k ohms. If it's 500 ohms or less, then the mini may not be able to drive sync properly.
On an old monitor like that, it is likely to have old fashioned components with axial leads rather than surface mount components. If you are handy with a soldering iron, you could find the offending resistors and bring the monitor up to a more modern, high impedance standard of 1.8k to 2.2k.

Problem Mac mini G4 with Panasonic 52" Plasma using s-video (composite)

I am upgrading my mac mini but until then I'd like to watch some movies on my new Panasonic 50" Plasma (TH50PZ80U). The first I connected them together using a DVI-to S-Video adapter it worked but with low resolution (can't remember). The resolution was fine for movies but not reading. When I tried to increase the resolution the screen became all grey and black (like when there's no the TV channel in the old days). I tried all of the following but nothing has worked:
1) Played with the mouse for an hour to try to change the resolution but kept starting new programs instead
2) Connected to my apple display cinema, change resolution to the minimum, and then reconnected it and nothing
3) Asked a friend to bring his laptop to do screen sharing but my OS 10.4.11 doesn't support this functionality
4) Tried starting in safe mode and it won't start in safe mode. It gets stock on the gray apple screen at launch
5) Tried getting an HDMI cable but this mac mini is not strong enough for the plasma screen. It kept going black after a few minutes
6) Tried using keyword shortcuts with SwitchResX but I couldn't seem to find the right sequence.
Remember that I tried to the above blind since the screen was all blurry.
Can someone help. Thanks

+I tried with an HDMI cble, through a DVI adapter, but it seems that my 1st generation mac mini is not powerful enough for that. It comes out at first but as soon as I start any application, it looses signal+
I'll ask again; what happens if you try starting in Safe mode connected by HDMI? I understand that with a normal start and running 1080p, the mini is not necessarily stable. But if you start safe, or start normally, and quickly change the resolution to something lower than 1080p, the mini should be "powerful enough" to run the Panasonic at 720p for example. That should not present a problem.
If you really just want to get back to using the S-Video interface at 640 x 480, you should be able to throw out the display preference files to get back to a clean start. That usually works. Try the following; in /Library/Preferences find the file com.apple.windowserver.plist and throw it in the trash or drag it to the desktop. Find also in /Users/yourusername/Library/Preferences/ByHost the file com.apple.windowserver.xxxxxxxx.plist where xxxxxxx is a string of letters and numbers and yourusername is the name on the main user account and throw that in the trash, too (or drag it to the Desktop). Then restart and see if function returns to S-Video when connected to the Panasonic.

Dual Display on Mac Mini

Hi there,
I want to have a dual display setup with my Mac Mini. There's also a twist. One of the displays is a regular monitor. The other display is a 46" TV. I am not too technically minded - is there a splitter or some kind of dual display "kit" I can pick up?
Thanks!

Which Mac mini? The new one has two video outputs on it, so two displays is not a problem.

Share cinema display between Mac Mini and MacBook Pro

Hello -
I am keen to get an LED cinema display to use on my new MacBook Pro - but I share my study with my children - so want to give them a MacMini to use.
How easy is it two swap between the MacMini and the MacBook Pro ? I guess there is only one input in the LED cinema display ???
Thanks in advance.
Andrew

Interesting - I have the same idea: sharing a 24" cinema display between a Macbook Pro for myself and a Mac mini for my wife.
The only problem I see is that the display doesn't have any Firewire ports. So if I want to use an external harddrive (or a mini-DV camcorder) on both computers when connected to the display, then I'd have to plug that into the computer instead of the display ...

Linking Thunderbolt Display to Mac Mini AppleCare

I've Recently Purchased a 2012 Mac Mini and A Thunderbolt Display. i also Bought AppleCare for the Mac Mini as well.
When i go to register the AppleCare to the Product, it gives me the option to Link a Display to it, but when i try to input the Thunderbolt Display's Serial# and go to the next step, it says that it is invalid.
What could Be the Problem? they were purchased on the same day...

Give AppleCare a call - 1-800-275-2273.
I didn't have any problems registering my products with the AppleCare that I purchased.

Can't use my apple displays with Mac mini

Hey everyone,
I've got a pretty strange problem, and I'm hoping you guys know of a solution to this.
Thing is, I can't use any apple displays with my Mac mini box. Whenever I try to do so I can see that the monitors are turned on, but the screen is completely black (doesn't flicker or anything like that). I know for a fact that both of the apple monitors I tried work.
However, monitors from other manufacturers work just fine! This has got me baffled, what is it about apple monitors that's got my Mac so confused ?

It's possible the analog VGA is working on your mini whereas the DVI digital output is broken. They are two completely different interfaces that just happen to share a common connector on the mini.
Can you possibly get your hands on another, non-Apple monitor that has a DVI input? I would say if all three are not working (two Apple monitors and a third-party one), then definitely something is up with the mini's DVI output.
