Applications :: Losing Monitor Resolution Settings During Sleep?
Apr 10, 2005
I'm using a Mac Mini (running 10.3.8) connected to an old View Sonic E95 monitor. No problems except that every time I leave the computer for a while it goes to sleep and "forgets" what display it is connected to. When I hit a key or whatever to reawaken it, the display resolution has been re-set to "VGA 800x600" and I have to tell it to "Detect Display" again..
Any clues? I have looked on the forums and Google with no success .

I currently have a MBP1, 1 running 10.6.4 on an external monitor with the ideal resolution at 1920x1200. From time to time, when I wake my MBP from sleep through external keyboard/mouse to have it run solely on the external monitor, it sets the display at 1600x1200, so everything seems squished vertically. After a fresh reformat, the problem persists, though it is less frequent. It's just a minor annoyance that I can't seem to find a solution to fix permanently. I usually have to go to safe mode and adjust the resolution back to normal. Alternatively, only sometimes if I put it back to sleep and wake it up again with the external keyboard, it will detect the right settings.

I have a few pictures I took with my digital camera and I want to print them and put them in a frame that is 11.5cm * 7.7cm. So, I need to adjust their size to print them that size.
I don't have a colour printer, so I'm printing off a library computer in colour, so I can't print them directly off my mac. I'm going to need to transfer them on a usb and open them in windows on a library computer. The pictures are in .JPG format since I uploaded them.
-So I went to Preview (program) and Tools > Adjust size.
-I typed in 7.7cm for width and it gave me a locked length of 11.1cm as that would probably keep the pictures proportionate. I'm alright with that.
But then, when I look at my picture, it's much smaller that the actual dimensions of 7.7cm. Then when I zoom in, it is pixelated. That'd odd because I'm actually reducing the dimensions of my picture.
How do I adjust their size so they print to 11.1 cm 7.7 cm?

I have a G5 Duel 2GHz Power PC, Recently I was losing the time, date and wireless settings so I assumed as my machine is now 4 years old the PRAM battery was up for renewal.This has now been replaced but I'm still losing my settings, not all the time but randomly, sometimes I lose my wireless key sometimes I lose time and date sometimes both, this can happen daily.
I have removed the (New) Battery and checked the voltage and it reads 3.6 Volts, I haven't checked this under load though, so presuming that the battery is OK, what else could cause this.. a failing System Board?

I have an HD (1080p) .mkv movie with subtitles and surround sound. Is there a way to convert this file into a format that iDVD understands without losing 1080p resolution?

I have a G5 Quad with an Ati x1900 graphics card running into a 52" Samsung LCD. This was working fine through a dvi-vga adaptor until I switched the monitor resolution from 1920X1080 to 1360X768 which is not supported by the monitor .....blank screen. I plugged another 19" monitor into the other output on the card and both work fine but as soon as I remove the 19" the 52" reverts back to the unsupported mode. I have reset the pram and tried booting in safe mode but that did not help me. From bootup the 52" works fine until just before the login screen, then it switches resolution......blank screen. Would anyone know where these settings would be housed in OS 10.5.1 so I can modify (delete) them?
Information:
G5 Quad
Mac OS X (10.5.1)

For some reason, approximately once a month, the Mac loses the wifi settings. This sends the clock back to January 1st and takes several attempts of reentering the network name and password before it is recognised again.
Also, the wifi settings seem to no longer be part of the keychain when that happens.
This is getting to be a pain. Does anyone know why this happens (it only happens on one of the Macs; others are fine)? What can I do to repair it for good?

Stayed with 10.6.8 for years and had no issues, then started to see problems with Safari, websites not loading, email problems, updates no longer available etc etc.
So I used Carbon Copy Cloner to make a backup, wiped everything, then a clean install of Yosemite. All went very well indeed!
I have 3 accounts setup on the one iMac (2011 model i7 Quad core). 2 of these accounts work perfectly, but the thing which is driving me nuts is on the 3rd account. I set the mouse tracking speed and remove the scroll direction tick, but whenever I log out, it resets itself! Every time I log in, I have to go to System Prefs and reset it all over again!
The solution is to setup another account of course, and copy all files over, but I'd prefer to work through this issue to find out whats causing it if I can.

just been noticing something weird happening with the battery on my 13" Ultimate Air I got just under a week ago,It seems that when I put it to sleep it still loses battery power? I had it 100% charged last night before going to work, went to work today and turned it on for about 10 mins just to go on Safari over wifi, this seemed to drop the battery to about 97% when I was done, so that's fine.
I put it to sleep again, have just come home from work and I wake it up, it now shows 93% battery? Am I missing something here? I know for a fact the machine definitely went to sleep.

Brand new iMac running 10.9.3 using a Anker 13 port hub..After wakening from sleep mode (this is usually observed after long periods of inactivity) I am finding that devices connected by USB are inaccessible. Reconnecting them does not correct the problem, only a restart will restore them.
Info:
iMac (27-inch, Late 2013), OS X Mavericks (10.9.3)

So I plugged-in my MacBook Pro (from DVI) into my Westinghouse 32" 720p LCD TV (into HDMI) which has a native resolution of 1366 x 768.
When I open-up System Preferences > Display I get a window on my MBP and one on the TV. 1366 x 768 isn't listed in the available resolutions. Some of the ones listed show "Interlaced" between parenthesis. If I click on the highest resolution setting available 1920 x 1080, the image flickers a bit and it is visible.

I picked up a new MacBook yesterday and I noticed a weird issue when coming out of "monitor sleep" mode, not regular sleep mode.
When I move the mouse, the external monitor shows what you see in the picture, kinda like a TV with no signal. The MacBook screen works fine so what I just do is unplug and re-plug in the DVI plug and everything is good again.
My 24 inch Dell monitor worked fine with my M1330 and other computers so I know it's not that. Does anyone have the same issue or maybe give me some light on this?

I am wanting to hook my iMac G5 (iSight) to my 42" plasma screen, courtesy of the Mini-DVI adapter. I am aware of what cable I need to get (DVI-D, if I recall correctly), I am simply concerned with the achievable resolution.
If any of you have hooked up your iMacs in this way, could you inform me what resolutions you all have been able to achieve? My plaz can display up to 1080i.

Sorry if this is the wrong place to post this. I have got the cables and connectors that I need to connect my mbp to my tv via the tv's hdmi port. My question is what settings should the mbp screen resolution be set to in order to get the best picture quality / size when playing itunes tv shows? Also what setting should the tv be on as you have the option of widescreen. 4:3, smart etc.

I'm a new mac user. Just bought a Mac mini with Mac OS X Lion (10.7.4). I was messing around with the resolutions on the display settings. I set the resolution back to the 1080p where it was when I first started messing with it. Now the color is off, the screen is not how it was before I started tampering with resolution settings. I've tried recalibrating the color but its still off. When I start my mac up in Safe Boot the windows and color look normal as if I changed nothing.

Here are my hardware specs:
Mac Pro 1,1
NVidia 7300GT (I need a new video card, anyone want to sell me one? [=)
2 x Samsung Synmaster 2494SW (native resolution 1920x1080)
Update:
I booted into windows 7 and I am now able to get both native resolutions.
Though, I am still unable to get both native resolutions (using DVI to DVIs) inside OS X for some reason. In OS X my second monitor is displayed as "VGA Display" and it completely black.
I am not sure why it works in bootcamp using Windows 7, but not in Snow Leopard. I am guessing this is a problem with the OS X configuration.

I have a Hyundai W240D 24" LCD monitor and it works perfectly in Windows Vista SP2 64 bit running under Boot Camp but when I restart the computer to use Mac OS X it only shows 1920 x 1080 as the maximum resolution rather than 1920 x 1200. I have zapped the PRAM, repaired disk permissions and run fsck -f in single user mode and still the problem persists. Does anyone have any suggestions for how to fix this?

I just purchased a Samsung Series 4 Model 530 monitor, 32 inch, with a resolution of 1920 x 1080p. Can this effectively be used as the main monitor for my new Mac Pro laptop? I can NOT find this resolution in the prefs anywhere, and do not know if I can really use this monitor. I work in print design, and as a result, I am always viewing typography in great detail.

I'm looking for an external monitor to plug my macbook into. Mainly working on Aperture, Microsoft office, and web surfing. Not watching movies or gaming on it. With my budget, the only IPS monitor I can afford is the 22" Dell ultrasharp. It comes with 1680x1050 resolution (or close to that). Also, its non-glossy, and I prefer glossy. Alternatively I can get a plain vanilla 24" TN monitor with 1920x1200.
I do need the extra screen estate, which is why I decided to buy a monitor in the first place. I frequently have to refer to multiple documents at the same time while working on Microsoft office, and Aperture would certainly benefit from more space. All these resolutions are new to me, my current desktop PC is still running on 1200x1024. Is there a significant difference moving from 1680 to 1920? Is it justified to lose the IPS feature (which gives better color and viewing angles, I've been told).

I have just purchased a new Mac Pro (august 2014) basic configuration ( see below)
Quad-Core and Dual GPU
3.7GHz Quad-Core Intel Xeon E5 processor
12GB 1866MHz DDR3 ECC memory
Dual AMD FirePro D300with 2GB GDDR5 VRAM each
256GB PCIe-based flash storage
From reviews seen so far the 4K monitors available do not achieve the 60Hz refresh rate...
The other issue is that the price of these displays is somewhat extravagant at the moment and since I intend to use my Mac pro for other applications and not Video and Photo editing I would like to ask whether a display of resolution (say 1920X1080) would work with my new Mac Pro.

I bought one LG flatron e2350V, and i'm trying to connect it to my macbook pro, it's connect through minidisplay port - dvi. When in system preferences if i choose use monitor it appears with great resolution, beautiful image. But if i choose "use identical image for both monitors" the resolution on the LG turns crap.
What should i do to have identical image (so i can have my macbookpro with lid closed) but have at the same time an awesome resolution?

Just bought a new 22' LG monitor and I have the Mini DisplayPort to VGA. When I connect my monitor to my MacBook all is OK until I try to chose the 1680x1050 which is the LG's prefered resolution. When I chose it, my monitor turns to black, then after a while it shows the picture for a second, then black again.. Is this a 9400m fault, or the VGA adapter fault?If I try a MiniDisplay port to DVI, will it work in 1680 x 1050?
All the other resolutions are shown ok..

I read a few posts that seem to indicate that non-mac monitor cannot display higher them 1680x1200 when connected to a Mac computer. A friend of mine is planing on getting a new Mac pro with a 30" Samsung monitor (2560 x 1600). Will he be able to run the monitor a max resolution?

Recently I plugged my HD Monitor to my MacBook and the resolution changed (on the external monitor). I went to Display Preferences but I do not get any resolutions above 1600x1200. When I first used this monitor, I could use it at 1920x1080 and now I simply can't. I don't know if it's a PRAM issue. I reset it but nothing changed.
I'm using a HP 2309m monitor in VGA mode using the VGA-Mini display port adapter. I use the monitor with a PC in DVI mode, but I never use these connection at the same time. I noticed something. When I first used this monitor, Mac identified it as HP 2309 when I opened the display preferences. Now, it only recognizes it as Display.

This happened before and a restart fixed the problem, but not anymore. Out of nowhere, I startup and I'm getting a message on the screen of my Samsung 2033SW that the resolution should be 1600 x 900 60mhz. This is a message from the monitor, not a Mac system message. But there is no setting for 1600x900 on the system prefs. I tried restarting, and so on, but nothing... In previous occurrences, somehow some way, I started to see the proper settings and then I just selected them in system prefs. But no longer. I'm stuck on 1024 x 768, the closest to the proportional resolution I'm after. I don't know of any way to force the proper resolution. Are there some .plist files I can delete? There are other issues with this machine which is old and I'm working around for now.

I just found out that if I use the "mirroring" mode, and I set the resolution to 1680x1050 and 60hz(my monitor max resolution/hz), it's all kinda blurry... But if I put in sleep mode ma MPB and wake it up "switching on" my bluetooth keyboard, the monitor in my MBP doesn't even start and it just use the external monitor. In this case, there's no more blurriness but the settings are the same! Then, I can even turn on my MBP monitor (pressing some random key on its keyboard) and nothing change, still no blurriness...
How can this happen? By the way, there is another funny issue: if I use this "trick", the applications that should run in "fullscreen" (not really fullscreen, just the window that use all the screen size), like iTunes, don't do it anymore....

I have a Macbook Pro 13 inch 2010 model hooked up to a NEC Multisync EA231 WMI external monitor. The monitor is supposed to have a resolution of 1920 X 1080, but my computer only recognizes 1600 x 900 as the highest resolution. I've tried both mirrored and extended desktop, and I've also hooked up the monitor through a DVI adaptor and through a displayport cable. An Apple support person suggested using a dual-link DVI adaptor, but according to the Apple site this shouldn't be necessary for 1920 x 1080 resolution (I've also heard that it's a buggy piece of hardware). Any suggestions for getting optimal resolution?
