Wrong resolution when Mini wakes

I have my Mac Mini connected to my Sony Bravia TV using DVI to VGA. The best resolution for the TV is 1360x768. However when my Mini wakes in the middle of the night, say to record something on EyeTV, because there isn't a detectable connected monitor (TV is switched off) the Mini decides that the display will 1280x1024. This is driving my nuts. When I turn the TV on, I have to hunt around for my mouse to find 'detect displays' menu to restore the to full screen 1360x768. This is certainly not wife friendly.
Does anyone know of a way to force the Mini to display at 1360x768 regardless of whether a monitor is attached and if it is switched on or off?
I would like to go DVI to HDMI but have failed to get as good an output as I can with VGA

SwitchResX is no solution for the kind of issue your kit is having. You hit the nail on the head when you said, "...there isn't a detectable connected monitor (TV is switched off)...". That's exactly what's happening. It's an architectural oversight in the Sony. Most computer monitors behave differently from that, e.g. it doesn't matter if the monitor is on or off, the Mac won't lose track of it.
Unfortunately, I don't know of anything but the DVI Detective that will fix the issue. Can you leave the TV on? Does it go into a low power sleep state that would still allow the mini to detect its presence?

Tv/monitor resolution switches when mini wakes up from sleep

I have a mac mini c2d with intel graphics on leopard 10.6.2 connected to a sony 46w4100 tv. After updating to 10.6.2 when it first came out (i had used 10.6 and 10.6 aswell before this and this problem did not occur) i immediately noticed an issue. when i put my mac to sleep and wake it back up, instead of outputting to tv as a media player so that i have access to detailed picture settings, it reports itself as a PC thus limiting what i can change and the picture quality. i mainly use this as an HTPC, and its a problem since wiht my tv(not sure if ohter tv's have this), settings for connecting to dvd/blueray player/satellite receiver are extensive and picture is sharp, vs connecting it to computer where you only have the option of text and video and the video is not as vibrant or sharp. if i shutdown the mac and start again ,ir goes back to normal, but if i sleep and wake up, this behaviour occurs. 10.6 did not have this problem neither did 10.6.1. infact with 10.5 my mini always reported as PC thus i had limited options but with 10.6 i was happy to notice it was fixed.
is there someway to avoid this other than just ensuring my mac never goes to sleep (wasteful since its not in use most of the day). is anybody else seeing this issue and do you think this is a bug or aws the 10.6 and 10.6.1 behaviour a "bug" that apple has decided to fix.

also note the topic may be a bit misleading, when the mini wakes from sleep it is still outputting 1920x1080 so resolution does not change. when i first turn on mac, the sony tv shows 1080p output, full screen, etc etc and all the settings. when i wake from sleep and turn tv on, it doesnt have any any of that info so it doesnt even tell me its 1080p but it is.

Display Changes Resolution When Computer Wakes From Sleep

I have a MacBook Pro bought in May of 2006. In the last year, this problem has been getting progressively more annoying to me. When the computer wakes from sleep (not every time, but most of the time) the screen will flash blue, then reset the resolution to 640 x 480, I think. To fix it, all I have to do is go to System Preferences and change the resolution, but when I do that, it pops up two windows, like it thinks I have a dual display set up. To fix this, I always click 'detect displays,' and it fixes it, but the next time I wake the computer from sleep, it does it again. This isn't really an urgent problem, but I would expect my computer to behave a bit better for me.
Thank you in advance for any aid you might give me.

Hi Lisel. I have a similar age MacBookPro that does the same thing. I don't really know how to fix it I'm sorry, I wish I did cause it's annoying. I just thought I'd let you know you're not the only one with this issue.
Basically, for some reason it thinks it has two displays connected, even when there isn't. To stop it being a total pain, make sure when it does come up with the two Display Pref windows to set them both to 1440x900, at least then when it does go dual display it won't be 640x480 and you can still read stuff.
I've also left the Display Pref icon on the top tool bar (next to the AirPort and Bluetooth and stuff), so I can just click that and Detect Displays. When it does that it figures out for itself it doesn't actually have two displays connected and so goes back to normal.
I know that's a workaround and not a fix, sorry. I'd be keen to know if anyone else has any better solutions:)
Thanks,
Mark.

Resolution Problems After Mac Mini Wakes Up

I have a 1.66MHz Core Duo Mac Mini hooked up to a Westinghouse LTV-27w6HD LCD TV. The screen is set to 1366 X 768 resolution and looks fine when the mini first boots up. Once the Mini goes to sleep however things go wrong. When it wakes up the screen is off center with the right side of the screen messed up. Any help?

Just a minor correction to an otherwise good set of suggestions:
Since this is an Intel mini, the PMU reset isn't the right procedure (Intel mini's don't have a PMU). For Intel systems, it's an SMC reset, which is almost the same procedure, but not quite.
To reset the SMC:
-From the Apple menu, choose Shut Down (or if the computer is not responding, hold the power button until it turns off).
-Unplug all cables from the computer, including the power cord and any display cables.
-Wait at least 15 seconds.
-Plug the power cord back in, making sure the power button is not being pressed at the time.
-Then reconnect your keyboard and mouse to the computer.
-Press the power button on the back to start up your computer.

Hi, I have a mac mini..all of a sudden when I wake it up in the morning it says I didn't disconnect y external properly and it will try to retrieve the information..it finally appearsbut it never used to say I should disconnect the external before...help

Hello, my mac mini has suddenly started displaying a warning sign when I wake it up..saying I didn't properly "eject" a device... It is referring to my external/backup hd {on which I store music files, photos, back up files, etc}. It has never happened until yesterday... and I have had the hd hooked up for over a year. Each night I just put my mini to sleep and when it wakes in the morning everything is fine... the only time I ever disconnect the external hd is when I completely shut down or unplug...the procedure then has been to turn off the mini...then disconnect the external hd and unplug it. This has always worked fine, then suddenly it says I haven't properly disconnected the external hd... I don't know what to do... am I supposed to use the eject button now before I shut down...and how can I do that... it will state that it is not able to be ejected because it is in use {the rotating photos in my monitor background are stored on the external hd}. I am puzzled... don't want to lose the info on my external hd...but I need to be able to put my mini to sleep. Help, please.

Have the pics allways been used off the external drive?
Open Console in Utilities & see if there are any clues or repeating messages when this happens.
Is Spotlight indexing that drive, or is it used by Time Machine?

Mac mini displays the wrong resolution

Hi everybody.
My Mac mini recently began starting up in the wrong resolution (1024x768, instead of the usual 1280x1024.) From my experience with older, 680x0 Macs, I reset the PRAM. This fixed the problem, but I find that I have to do it every time I restart the computer.
Is there a battery inside the mini that needs to be replaced?
Thanks.

Mr E,
Try using the Finder to search for files with the name 'windowserver' (no quotes of course. You should find 2 or 3, including one with a string of additional alphanumeic characters. Move all three to the trash and then reboot.
These are the files that control screen properties, and the system will recreate new ones in the absence of the originals. Startup may produce an erroneous resolution if your screen is not tightly connected and thus not properly recognized, but if so, aside from checking the connections are firm and tight as suggested, you should then be able to set the required resolution and have the system retain it correctly.

My web page uses svg images, but when the svg's are printed by Firefox they are rasterized at the wrong resolution.

I have produced a web page which uses svg images. One of these is here:
http://donwagner.dk/JZSS5.4.svg.
The svg's are produced by Adobe Illustrator, version CS5. Viewed in any browser the images look good at any magnification, but when I print the page in Firefox the image is seriously blurred, seemingly because the rasterization uses the wrong resolution.
The same happens in all browsers, not quite so bad in Chrome but still not perfect.
Do you have plans to fix this bug, or do you have a workaround?
Regards
Don Wagner

In my experience, print quality settings such as dpi/ppi are hidden in your printer driver settings and not directly available through Firefox's UI. In the print dialog, if you click the Properties button, you hopefully will gain access to this setting. Obviously native web resolution (96ppi) can give disappointing results, so hopefully you can find a place to increase it.

Mac Mini wakes up from standby automatically

Hi,
My Mac Mini wakes up from standby automatically. Waking up via network is disabled and I use an Airport Extreme, a USB mouse (not from Apple) and a wireless Apple keyboard. OS X version is 10.5.8.
I have the Mac Mini since about 10 months now. Almost 1 month after I bought it, I had the this problem but thought I am doing something wrong or my wife has forgotten to turn it off
After a while it was OK. About 3 months later it startet waking up by itself again. I called Apple Care (although the 3 months support was over). They tried to help, but there was no progress. It waked up again and again. After about 1 month it was OK again without me having done anything, no installations, no system updates.
One week ago, the Mac found some updates at Apple and installed them. Since then I have again the problem! I contacted again Apple Care and again they could not help. They just want me to pay for an extension of the Apple Care package, although they could not help me in this case!
Now I want to try it myself getting support by people in this forum. I hope there is someone with experience about this case.
I am not much experienced with OS X, but I will try to answer questions that could help me resolve this problem.
BTW, I searched for a similar topic and found one ("My MacMini always wakes up from standby") but in that case the wake up feature is activated by the user. In my case this feature is deactivated, as mentioned above.
Thanks
Cheers

Hi,
sorry for the delay, but I was on a business trip.
@Bsteely: Sometimes it wakes up immediately because of loosing connection to the keaboard when I send it to sleep. I suppose at the beginning of the sleep mode it into sleep mode, the keaboard connection is closed, then the keyboard "thinks" there is a problem and sends a message to the mini and the mini just wakes up again showing that the connection to the keyboard was lost but established again! This even happened as I had unselected the checkbox "Allow Bluetooth devices to wake up this computer" in Preferences -> Bluetooth -> Advanced.
But there are also times when the mini does not wake up so quickly. It just wakes up after hours. I had a look at Console.app as you suggested. Very weird to me indeed Well there I found something like "Wake reason = OHC2" or "Wake reason = OHC1". Unfortunately I cannot find older logs there.
@Boece: Hi and thanks for helping!
Well, I will try the update as soon as I can. By now I have no external harddisk to first save my data before doing the big update. But I am going to buy one soon.
Well turning off the monitor is OK, but the harddisk can wake up anytime while the mini is turned on as the OS might need to do something from time to time. And I don't want my computer to consume electricity even if it is such a small one like the mini. I'm a kind of green dude (but not from Mars ). And the sleep mode is interesting for me as I have very often many different Internet sites and some applications running, so I don't need to close them before turning off and open all of them again when turning on the mini.
Regarding other IR devices: The only IR device now is the keyboard. I even took out the batteries and the mini still woke up over the night!
Thanks again for your support guys. Please let me know if you have any further information of ideas.
Cheers

External display incorrect resolution when MBP lid is closed

Hi,
I've just bought a 24" Samsung monitor for use with my 2011 MBP. The optimum resolution for the monitor is 1920 x 1080. I ahave it hooked up through a minidisplay to vga adapter. When I have this resolution selected in extended display mode it works fine, however when I close the lid and run the monitor with the same resolution as the main display, the image gets squashed and the screen flickers, I can also see faint lines in the background and the display is not centred, leaving black gaps on either side of the screen.
The frustrating thing is it was originally running fine before I temporarily changed the resolution in display preferences when in closed lid mode. Is there any kind of fix for this?? I know it's not the monitor's fault because it's displaying the correct resolution when in extended desktop and on other systems.
Any help would be greatly appreciated!

What else can I try??
Any bossy third party apps trying to control things?
Run Apple Hardware Test, and/or a trip to the "genius" bar.
No thrid party apps have access to my display prefs as far as I know. And the hardware test did not indicate that anyhting was wrong. I would like to leave the "Genius" bar as a last resort, they weren't much help last time...
Ok so moving the menu bar is allowing me to use the external as native desktop, but this doesn't fix the resolution problem when I close the lid even though the resolution in display prefs is set the same. Is it possible then to tell the mbp not to sleep when I close the lid?? I know you can do this in windows. Please note that I am still using Snow Leopard v10.6.8

External display issue when Macbook wakes up

Hi there,
I have an external display (Samsung 920nw) used as an extension of my desktop. When I go to sleep so does my Macbook... I close the lid and the computer goes to sleep mode within seconds (the white led on the front right slowly flashes confirming that the computer got to sleep).
The problem starts in the morning when I wake up the Macbook. The white led is still and not flashing anymore and when I lift the lid only the external display works with a poor resolution. The macbook display remains off. To solve the problem I need to detect displays and rearrange everything again between the screens.
I am not sure but I believe that sometime during the night the Macbook wakes up and he thinks that I am using the external display as the only display.
I want to lift the lid and both displays to be working as they were before going to sleep mode. Is anyone facing the same problem and/or have any clue of what is happening?
I have a bluetooth mouse and a usb hub with printer, pen drive, external hard drive attached to the macbook.
Thanks for helping.

Could be caused by a backup drive or some other application running in the background. There's no way to be sure without looking at your crash logs. I keep my computer on but I always close down my apps at night to protect them from power outages.

Cannot change display resolution when connected to external display

On my 2.0GHz 13" MacBook, I have no problem with the display resolution when connecting to external display/projector when I am running in Mac OS, everything work perfectly! But things start to get messy when I am running in Windows VISTA 32 (installed within the Boot Camp 2.1). Whenever I connect to any external display/projector via a MiniDisplay-to-VGA cable, the resolutions on both my MacBook LCD and external display/projector drop to 640x480. And i am not able increase the resolution in the Display Settings. Does this mean that I have not installed the latest version of display drivers? Or is it that Apple did not provide the VISTA 32 drivers (in Boot Camp 2.1) that is compatible with the Mini Display port.

Cool!
I'm glad you have it fixed.

CS5 frozen when iMac wakes from sleep mode

This problem just started, and I don't know if it's an INDD problem or a Finder problem. When I wake my computer from sleep and try to access INDD I can't. I click on the application icon in the Dock and it won't come to the front. All my other applications will. I have to force quit INDDD every time, and re-open it. This is whether I have a document open or not. I tried zapping the PRAM and shutting down, unplugging everything and starting back up but neither of those helped. Any advice or ideas of what could be wrong?

Best to post the actual URL. I assume this is: http://pastebin.com/raw.php?i=d6TgEEMv.

So, disable it to confirm. Then make sure you're running the latest version, and if so, take it up with Extensis. I believe they have free support on their web site.
Also, you should upgrade InDesign to 7.0.4, you're running 7.0.3, and there were a lot of fixes.

Firewire dismounts when computer wakes from sleep

I have a G-Drive mini hooked up via the firewire 800 port on my MacBook Pro (early 2011 - 13 inch). The drive is directly connected to the laptop but serves also as a pass through for two other firewire drives (non G-Tech). I usually only have the one G-Drive turned and turn on the other drives only when I need them.
The issue seems to be that when I wake my computer from sleep the drive will disconnect itself. I get the dialogue warning of ejecting a drive improperly and then have to shut off the drive and turn it back on for it to mount again. When I shut off the drive in this conidtion I get the standard spinning drive beep sound that tells me it was not meant to be turned off that way... So I assume that the computer or the drive are not communicating properly when the drive is connected and the computer goes to sleep.
Answers to inevitalbe questions: The drive is not hooked up to an external power source -- I have not tested the issue with a different or powered firewire drive -- I have not noticed the issue when all drives are connected via daisy chain -- None of my USB ports seem to be effected (knock on digital wood) -- The only application that is ever left open that may need to access the drive when I leave my computer and it goes to sleep is iTunes
Issues within issues: This does not always happen, but it seems to have been happening a lot more often.
Running Mac OSX 10.6.8
Currently using iTunes version 10.5 (although I highly doubt this has anything to do with the issue at hand)
If anyone has any insight on the problem, a fix or even if the issue is known or being ignored I would greatly appreciate the knowledge.

UPDATE:
I have started to turn off Bluetooth at night before I put my computer to sleep. I HAVE NOT HAD THE FIREWIRE RANDOM DISMOUNT PROBLEM SINCE. I do not know if this is a freak coincidence -- but so far, so much the better for my firewire drive.
Hope this helps someone else down the line... eh hem...
