Mac mini Monitor Problems

whats good,
I just got my Mac mini in the mail.
plugged it in to my dynex dx lcd 1909 tv screen.
it works for about 10 seconds, mouse, keyboard works fine.
Then goes awall
its connected with hdmi
i already swapped the cables and I still get the same issue.
cant be the TV right? I hear minis got issues with monitors.
(please excuse any upside pics idunno y , im on an iPad)

That is an old monitor

You can try with a mini displayport to VGA connection and use the VGA input on the TV.
Better yet I would get a newer monitor. You can get a good one on Craig's List

My mac Mini has problem rendering images and video

THE PROBLEM:
My mac mini has problem rendering JPEG image. There are strips on the images. Other images such as GIF, PNG, TIFF, and BMP are displayed nicely.
The images shown in the links below illustrate the problem:
http://www.flickr.com/photos/terencewong/71481156/
http://www.flickr.com/photos/terencewong/73360989/
(Please note that this image is grabbed from my faulty Mac Mini and saved into TIFF. For uploading purpose, I converted it into JPEG on ANOTHER computer.)
For movies, AVI can be playback without problem. But when it is converted to MPEG, it looks like an untunned TV channel.
FIXES TRIED:
I did erase and install 3 to 4 times using both the install disc and my Tiger Family Pack. All ended up with strips on the JPEG images and the generated MPEG movies.
I've also tried to flash the firmware to 113-xxxxx-124 using ATI's october 2005 universal ROM update, however, the ROM Revision shown in System Profiler is still 113-xxxxx-116 no matter how many time I reboot the system.
INVESTIGATION:
Yesterday, I did some research and got to know that JPEG and MPEG are using DCT (Discrete Cosine Transform) for decompression. And the ATI Radeon 9200 chip provide such a transform on hardware basis, which free the CPU from doing something else. Feel free to point out my inaccuracy.
HARDWARE SPECIFICATION:
I bought the Mac Mini in the last Februray.
The system Boot ROM version is: 4.8.9f1
Display card is ATI Radeon 9200
Chipset Model: ATY,RV280
Revision ID: 0x0001
ROM Revision: 113-xxxxx-116
A POSSIBLE CONCLUSION:
I suspect that it is this part of the chip (the DCT) that is faulty.
Anyone know how to fix this problem?
Many thanks!

Assuming that your display is tightly connected, thus the problem is not caused by something as simple as that, the fact that a full erase and install has not removed the problem would, I think, point to this being a hardware issue, and given that everyone's mini (with the possible exception of some of the latest ones) has the same video chipset as yours, and do not suffer the problem that you appear to, it seems very likely that your mini has a fault which is in need of repair.
If you have an Apple Store nearby, I would take it there to have it checked out - at the very least they should be able to replicate your problem using an in-store display, and if not, thusly suggest it's something external to the mini and concerning your display or something very unusual in the immediate environment of the mini. If you don't have an Apple Store in reach, I'd take the system to an Apple authorized service provider since at the present time it is under warranty.

2010 mac mini - monitor goes dark every few sec's problems since Mavericks Install

My Wife updated her 2010 Mac mini from Mountain Lion to Mavericks and ever since, after start, up the display intermittently flashes a dark screen, every few seconds. (within 3-10 seconds or so, there will be another period of dark screen, that may last aprox. 1- 6 seconds. The timing of this changes constantly. The finder and all apps I have seen are affected in the same way. it seems to be an all-the-time problem
the monitor is an OptiQuest Q9, and the system connects via an Apple mini display to VGA adapter (supplied with the mac mini) , then a vga cord into the monitor, which has a native resolution of 1280 x 1024.
The only workaround we have found is to boot the mac with the monitor cable disconnected, then reconnect the monitor cable after boot up is complete. In that case, the monitor does not flash, until the mac is shutdown or restarted again.
Steps I have already tried:
Zapped P-Ram
Reset SMC (shutdown, waited with power unplugged, then reattached power and rebootted
Repaired disk permissions,
repaired disk
re-download and reinstalled mavericks fresh.
changed display prefs for resolution, detected displays, etc.
Changed background picture.
I don't know where to go with this anymore, and it has already taken a lot of time.
Who's got a Fix?    And if there is no fix, how do I revert from Mavericks to Mountain Lion?   The mac mini came with Snow Leopoard.

Problem Fixed!
I found another page that referred to resetting the PMU (http://support.apple.com/kb/ht2183) , which controls things like wake and sleep:
"If the settings in the PMU become corrupted, it can result in operational anomalies such as your computer not turning on, not displaying video, or not waking from sleep, among other things. In these situations, you may need to reset your computer's PMU."
Anyway, it is pracitcally the same proceedure as resetting the SMC (SMC reset= Shut down, disconnect power cord for 10 seconds, reconnect power cord, wait 5 more seconds, turn computer back on)
but it is slightly different:   (PMU REST = Shut computer down, disconnect power cord for 10+ seconds, reconnect power cord WHILE SIMULTANEOOUSLY PRESSING POWER BUTTON, let off power button for a few seconds, then press power button again to restart the mac mini.)
After this the display problem was fixed, but the fan ran at high speed, so I did one more SMC reset as described above. Now everything is in order.   This also fixed the issue of the mac mini not waking from sleep unless the power/sleep button on the mini was pressed (it wasn't responding to the keyboard to awaken). Now it's all good.
Hope this helps somebody else...

Mac mini monitor resolution

Hello,
I bought my mac mini today ( 2.6GHz dual-core Intel Core i5 - Intel Iris Graphics - OS X Yosemite ) I connected using the DisplayPort DVI cable to my Viewsonic vx992 monitor. I have been using this monitor for my Windows XP which used to give me 1280x1024 resolution.
When I connect the new Mac to my screen is work but I with poor monitor resolution .. It's 1280x1024 but poor not clear
I'v been used this monitor with Windows with the same resolution and the monitor resolution was excellent with Windows.
I connected the Mac with Samsung Smart TV via HD cable .. The monitor resolution is excellent
This is the converter that I used:
http://www.amazon.com/gp/product/B007KB0EGC/ref=oh_aui_detailpage_o00_s00?ie=UTF 8&psc=1
Now, I'm conflict .. Is the problem with the convert that I'v been used or from the monitor ??

Hi IIIaass
I don't know if the screenshot will showing you the noise that I talk about ,, there is a little noise in the text for example .. I work for while on my monitor and I know the resolution quality and the clarity that should be,, and I don't want to buy new monitor then I discovered that the problem was from the Adapter.
Thanks again .. and please tell me what's the best HDMI converter to DVI if you know about it.

Mac Mini Monitor Blacking out

Hey guys,
I have a 1.4ghz G4 Mac Mini and i recently purchased a samsung 205bw lcd display. I am running on the native resolution of 1680x1050 60hz refresh rate (the recommended settings for the monitor)
Overall, the monitor works great until i try to watch video fullscreen. For some reason in VLC or Quicktime, after a while the screen begins to flicker than turns black. I ran every diagnostic that samsung has and there is apparently nothing physically wrong with the monitor. I was wondering. I downloaded SwitchResX but i wasnt sure which settings to change if anyone had any ideas..
thanx in advance

Got a Samsung SyncMaster 204B and having problems with a Belkin DVI/USB KVM switch. When switching form PC (WinXP) to mac mini I often get this blackout/flickering you all mentioned
Apple has to do something about that.

New Mac Mini USB problem

I have a brand new Mac Mini (December, 2011, 10.7.2) as well as an older Mac Mini (circa 2005, 10.6.4).
I bought a new GearHead USB wireless mouse to go with the new mini.
The mouse works fine on the old Mini (and also on a Windows PC).
On the new Mini, the mouse works until the Mini hibernates or powers down. On wake-up, the mouse doesn't work until I unplug and replug the USB transmitter. This is the case on all USB ports on the Mini, as well as on the keyboard and monitor USB ports. It doesn't matter which port I use or which port I unplug and replug into - I always need to unplug and replug the transmitter to get it to work after power- or hibernate-cycle.
Note that I have also tried a Logitech USB wireless mouse and an Apple Bluetooth mouse and they both work fine on both the new Mini and the old Mini.
The problem is only occurs between the Gearhead brand USB mouse and New Mac Mini (10.7.2).
I assume that the problem is that the mini is powering down the USB port and not refreshing it after power cycle, until I unplug and replug the transmitter. Alternatively, I suppose, the transmitter could be asserting itself early in the boot process before the Mini is awake enough to hear it. In either case, it seems that the band-aid fix is a command-line to force the OS to refresh the ports, but I can't find any reference to such a command.
Thank you for any help you can provide.

Hello,
I assume that the problem is that the mini is powering down the USB port and not refreshing it after power cycle,
To me it seems like when the usb is powered down the trnasmitter loses the signal with the mouse, i think your mini is perfectly fine, even though the mouse works fine on the old mini I think its how the transmitter handshakes with the new mouse on the new mac mini. Do you have a new mouse of the same brand that you can test and see if it has the same issue...
If so then it forsure the transmitter... not the mini... else take your mini in for health check.
good luck, let me know how u go...

Mac Mini Monitor

Just bought a new ViewSonic 20" monitor from Buy.com and it appears not to be compatible with the Mac Mini - only G3, G4 & G5. Any suggestions on a new compatible 20" monitor for under $300??

Yes, this is an all-to-common and unfortunate problem with the Mac mini and several third-party monitors having 1680 x 1050 resolution. The problem is the timing will have a dot clock above 135 MHz which presents problems for the mini in some cases. There are really only three things you can do; one is to use the VGA interface (requires an adapter), the second is to use a program like SwitchRes X to lower the dot clock and stay with the DVI interface and the third is to return the monitor for something else. If you want to go the SwitchRes X route, download and install it (get the SwitchRes X Control Panel version and not the full version of SwitchRes X) and then write back to this thread and I can take you through the steps you need to perform. You can also get more info from this thread:

Mac Mini Sleep problem - help!

I have a new Mac Mini 1.83 and a new Envision 22" LCD monitor and when I put the Mac Mini to sleep and click on the keyboard, the MacMini comes out of sleep but the display screen stays black. If I manually set the computer to sleep a second time and take it out of sleep a second time by clicking on the keyboard, then the display works properly. But I have to put it to sleep and make it come out of sleep TWICE before the Envision display works properly. Any ideas about this problem?

I have that problem since Quicktime 7.1.6 update (or the Airport Update, can't say).
When rebooting the display stays dark, but everything comes up fine. When I put in the Installation CD, the display turns on.
(DVI-FullHD, as before).
But after the "blank" screensaver gets activated, the display doesn't turn on again, not even using the CD.
(Although everything else still runs fine.)

How i fixed my mac mini dvi problems

Hi,
I bought an 200W6 20inch tft philips screen on saturday. When i connected it to my mini i noticed that i wouldn't return to an on state after the monitor stanby, also it took very long to recognise my tft after boot( like 5 mins or so) then when i ran the flurry screen saver everything looked fine but after 30 sec. there was snow and all sort of distortion. So clearly my monitor didn't work well with the mac mini.
After reading the topics here i was shocked to see that so many people have problems with there displays, and there is no real solution.
I tried to run the ati firmware update, and after that all my problems are gone. My monitor show the apple image right away, and the screensaver doesn't crash or disort I'm very happy now, i hope the firmware update can help you guys aswell. Try it out...

Hello. Thanx for the link, but i had tried this one already! This one says during the installation: This program does not upgrade Apple OEM hardware, such as the Powerbook, iMac, eMac, Mini or factory!
I have tried it and it does not help and does not install right. My mini has the following graphic rom and Monitor attached:

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.

Mac Mini Overheating Problem

Hello everyone!
I have a Mac Mini that I bought in October 2009 and it's suffering from overheating. I am using Temperature Monitor to see the temperatures reached by different components. For example, the temperatures that the Mac reaches under normal load (browser, messaging and mail) are:
CPU A heatsink: 51 C
CPU A Temperature Diode: 53 C
CPU Core 1: 38 - 40 C
CPU Core 2: 38 - 40 C
HDD Bay 1: 45 C
Northbridge Position One: 54 C
Smart HDD Hitachi (Fujitsu at work): 48 - 56 C
Wireless module: 54 - 60 C
Now my biggest concern is the temperature of the HDD which is way too big (even when using the Mac on normal load doing nothing fancy)!!! I've tested today the Mac Mini that I have at work and it's the same story. Running the HDD at this temperature will cause it to fail very quickly. I've tested the temperature that the HDD from my laptop gets and it is 38 - 40 C.
What to do about this? What temperature readings do you guys get? How to cool down the HDD?
Thank you for your help.
Cocan Lucian.

You shouldn't worry about these temps.
Keeping the CPU cool isn't necessary. If the CPU is operated within the temperature spec it will generally last longer than other parts in the system. If you manually increase the fan speed to keep the CPU cooler then the the fan will probably fail first. Do you hear a lot about Apple computers with dead CPUs? I don't. We generally discard systems before the CPU fails.
As for the disk, it seems to be a myth that operating modern disks at higher temperatures is bad for them. A case study done at Google, and they have a LOT of disks, says that high temps are not a problem:
labs.google.com/papers/disk_failures.pdf
A friend in the disk drive industry says that manufacturers agree.
But, if it makes you feel better to keep your stuff cooler -- then by all means do it.
Keeping it cool won't hurt it.
So what are the temperature limits?
First if you are using smcFanControl, the temp it reports is not good for deciding if you are in trouble. It reports an on-CPU diode which is always a LOT higher than the actual CPU core temp. At the moment my Mini is cranking and the diode temp is 15 C. higher than the core temp.
To get a better picture of your temps you can download:
http://www.bresink.com/osx/TemperatureMonitor.html
The CPU in my early-2009 Mini, a P7350, has a Tcase spec of 90 degrees C. That is the maximum operating temperature of the CPU case at the geometric center. The core temp limit will generally be a fair bit higher than that, I hear at least 5 C, but I can't find that a core temp (which is probably Tjunction Max) in the Intel specs. The default fan control algorithm for my Mini seems to try to keep the CPU core temperatures at or below 80 C. It doesn't speed the fan up from the default 1500 RPM until the temp gets nearly that high.
The late-2009 2.53 GHz CPU is supposedly a P8700 which has a Tcase spec of 105.
The disk in my Mini, a 320 GB WD Caviar Black , has an operating temp range of 0° C to 60° C.

How can I use screen share of my mac mini? Problems validating

I recently purchased a mac mini to act as my home media server for audio as my airport express was not playing nicely with my Peachtree DAC. Anyway, I have set up sharing on the mac mini and can't figure out how to connect from my wife's Macbook, or her iPad. (I use a PC, so would welcome advice if available on how to connect across platforms as well.) My goal is to set up the mac mini without a monitor or keyboard connected to it and have it sit with our main stereo.
I am able to connect to the mac mini via my wife's macbook IF I ask for permission and I grant it from the mac mini. However, I am unable to connect no matter what I try if I try to log in as a registered user. I have tried to add her as a user to the mac mini, I have tried to log in as a guest, and I have tried to log in with a password but no matter what I try, I get an authentication error when I try to log in as an authorized user. For more clarity, here is what I have tried:
1. Added authorized users on the mac mini. I created a user name for "jeff", "maureen", and "lastname_maureen" on the mac mini and provided a password for each user. "jeff" and "maureen" are just created on the mac mini, and "lastname_maureen" is the user name of my wife's computer. I confirmed the passwords, and still am unable to connect. I have allowed any user on the network to access screen share, and no matter what I do I get an authentication error. Again, if I attempt to log in from my wife's computer by asking permission, it works fine but I can't figure out how to set up an account to login. Please help. Thanks!

Have you tried connecting one to the HDMI output, and another to the Thunderbolt port (with the appropriate Mini DisplayPort-to-other connection adapter as needed)?

Mac Mini Mail Problem

Hi - I recently bought a Mac Mini so that I could have a desktop and a laptop (I'd been using the Titanium G4 as both) and I have been having trouble with the email on the Mini. Right off, I should say that the G4 had 768MB of RAM whereas my Mini only has 512MB. But the Mini is 1.5 GHz versus just 800 MHz for the G4. (I clearly don't know which of those matters more in a situation like this.)
Anyway, whenever someone sends me a large file now, it takes a dog's age to get it on the Mini. And while it's clearly downloading it in the background, it seems to ignore if I delete other emails, etc. For example, I might read 10 emails and delete them, and notice that I have wait for some attachment to download, and minimize mail in the interim. When I open it again, those same emails that I deleted are in my inbox again. Occasionally, I have gone to mac.com to delete files, and eventually my mail app notices this and deletes them as well, but clearly large files are causing a problem when they're sent to me.
It's not a bandwidth issue, as my G4 handled large attachments way better with the same Internet connection, and continues to do so while wirelessly connected to it. My guess is it's the RAM, but I really don't know. Do I need to go out and double the RAM on the Mini to make this stop?

Please follow these directions to delete the Mail "sandbox" folders. In OS X 10.9 there are two sandboxes, while in 10.8 there is only one. If you're running a version older than 10.8, this comment isn't applicable.

Mac mini Overscan problem

Hello, i just purchased a Mac mini and have connected it with DVI to HDMI onto my Panasonic plasma TV. The problem with this was if i turn overscan on the display is too big and is extended over the sides and some area isn't visble to me. If i turn overscan off there are black areas which is not covered around the sides of the screen. I have never had this with my PC connecting to this TV with HDMI DVI. But for some reason this problem is happneing to me right now...is there a Mac special software that can adjust the screen size so i can stretch the display around to manipulate it to a full screen size without anything being cut out or under cut in my display?

When you connected the PC and had no trouble with overscan, is there a way to capture the details of the timing involved? Because if you apply the same settings from the mini, there is no reason the TV shouldn't react to timing in the same way, meaning no overscan.

Mac Mini Audio Problem

Hi,
My Mac mini is only sending sound to one side of the headphone. I can get sound on the right but no sound on the left. I'm wondering if the sound card might need replacing ???
Any help would be appreciated.

Actually I'm trying to hook it up to my stereo so I was trouble shooting with the headset as I only get sound from one speaker. The Bose rep suggested I try a head phone to make sure the problem is coming from the mac mini. Is it possible to hook up to a stereo via a usb?(USB to Stereo input cables?) Also do you think that would help? I've tried new head phone to stereo cables between the two and same problem....
