How to reset display settings?

My Sharp TV only support 1080i, so I use a DVI-DVI cable to connect a monitor, then use Mini DisplayPort to HDMI adapter connect Sharp TV.
Then boot Mac mini, I got Open Screen on Monitor, and I set HDMI adapter to 1080i, then I power off and unplug DVI cable and boot again.
Well, I got what I want on Sharp TV, it is 1080i, but I found a 720p, I selected it, now the TV becomes to black screen with "Invalid video signal"!
I reconnect monitor, so Sharp TV is ok, but if I unconnect monitor, the sharp TV will be black screen.
I thought it might be some display settings are saved, because it was good when I first use TV after set to 1080i, but I selected 720p that is PAL TV, not for mine NTSC TV, after that selected, THe sharp TV can't be used alone, how can I reset display settings? what can I do for this case?
Please help me, GOD!

In the folder of your main user account, which is generally a folder with your name on it, find and open the Library folder. Then in the Library folder open the Preferences folder. In the Preferences folder open the folder named ByHost. Inside that folder is a file called com.apple.windowserver.xxxxxxxxxxxx.plist where xxxx is a string of numbers and letters. Drag that file out onto the desktop and restart the mini.
When OS X restarts, if it finds the above mentioned file missing from the expected location, if should build a fresh copy of the file in the original location. The fresh copy will have default values in it so the Mac will forget that bad setting that happened. Hopefully that will cause the display to work again.

How to reset display settings? 120 hz over HDMI on 2014 MBPr makes screen go black

Hi, I have a 15" 2014 MBPr with the 750m. Recently, I bought a TV, a vizio M422i-B1. One of my main reasons for buying the TV was to use it as a third display for my mac. I have two displays already connected, a 27 inch 1440 display over thunderbolt, and another 23" display that is 1080 and connected over the other thunderbolt.
I got the TV mounted above my desk, and ran an HDMI down from the TV to where I put my laptop, and plugged the TV in to the computer in the HDMI port on my mac.
It worked, but the refresh rate was set at 60 for the TV on my computer, but since my TV is 120Hz, I set the refresh rate in display settings to 120. It worked fine, and the mouse movement on the TV was more normal looking, so I was happy.
I put the computer to sleep a little later, and came back, and it wouldn't wake up, even after disconnecting all the displays and other peripherals, it would not wake. I restarted the computer, and with nothing connected it rebooted and worked normally.
I connected everything one by one, USB stuff first, fine. 1440 display over thunderbolt, and everything was fine. same with the 1080 display.
I went to plug in the TV again, and everything went black. I had to restart the computer without the TV plugged in to do anything. Restarting with the TV plugged in to the mac doesn't fix anything.
I know my issue is the refresh rate for the TV being set at 120Hz, and I have to change it back to 60 Hz, my problem is that as far as I know I have to have the TV plugged in to change the refresh rate, but if I plug the TV in it kills the computer. Is there a way to reset the display settings so that it doesn't "remember" that I want the TV to be 120Hz?

Did you ever figure this out?

How to reset network settings

Hello, I cant figure out how to reset my network settings on my macbook pro
I'm doing this because recently, in an effort to make my wireless work better (just bought a new router and it works great) I added an internet proxy to my network preferences (I'm ignorant to what a proxy actually is) and ever since then facebook and espn do not work on my browser. This is the message it displays on Google Chrome:
Oops! Google Chrome could not connect to facebook.com
Try reloading: facebook.com
Additional suggestions:
Access a cached copy of facebook.com
Go to facebook.co
On Safari all it says is that it cannot connect to the surver. After some proding on chrome, it told me that I should unselect any proxy's that were selected so this is what hinted to me that the reason I couldn't access these sites had something to do with the proxy meddling I did earlier. Even after unchecking all proxy settings it still doesn't work. PLEASE HELP!!!

Ok It looks like it reset the settings on the network however I'm running into the same problem with the websites I'm trying to access. Do you know how to fix this?

How to reset display resolution on a MacBook Pro

Hi,
My MBP 15.4 /2.4GHz display is stuck at a low colour display and I am unable to get it back to normal. I was working in MS Remote Desktop Connection, switched into OS X's Universal Access in System Preferences and that's when the fun started.
I've tried resetting PRAM using CommandOption+PR, but to no avail. My display settings in System Preferences show what one would expect - 1440x900, millions of colours. Changing these and switching back does nothing.
The thing is, when I start up, the desktop shows the display as it should be for a split second before it garbles the display's colours. It looks like an old Win 3.x box with 16 colour settings.
Is there a config file I can delete to reset the display, or some other way round this? Any suggestions would be much appreciated...
Cheers,
buddsbrains

Called Apple support, turned out to be a corrupt preference file; I renamed the preferences folder & rebooted & that resolved the issue. Now have to rebuild / copy back my old preferences...

VGA CRT will not "wake up".. help please. Reset display settings shortcut?

Hello everybody,
I have a mirror drive doors G4 Tower, Dual 1.25 GHz.
I have an ADC and a DVI out from the computer. Just had damage to my old studio display so I am attempting to use just one CRT running from the DVI... w/ a DVI to VGA adapter.
The first time I tried this w/ a CRT it worked fine... I played around w/ monitor settings... still worked fine. Shut down... unhooked CRT and moved that CRT away.
Tried using it with another CRT and the new CRT never started up... remained on stand-by/sleep.
I tried with another moniter... this time a LCD/Flatscreen... again VGA and it did the same thing, EXCEPT... this time when I connected the LCD to the adapter and then plugged the adapter into the DVI on my tower the LCD screen would turn on for about 1 second and display my login page. The picture was not perfect though... it was distorted someway.
Went back to the first CRT... now this one didn't work.
I think that maybe I have to reset my display settings with some sort of shortcut or something... maybe it's on the wrong frequency?
I don't know... any help much appreciated. I hate having to use this PC.
Thanks,
James

Turned out to be a faulty DVI to VGA adapter.

Can you start up in "safe mode"? If so, you can reset your display settings and reboot. If not, you have a problem either with your video card or your DVI/VGA adaptor

Reset Display Settings

Hello,
Ive just did the Display Update and it reset the screen resolution to 800/600 when it was booted again. When i changed it to what i thought was the right screen resolution, the display turned to black and the monitor displayed a "Not supported" message. I tried to reboot the mac mini using Safe Mode (holding shift) but it wont reset the display for some weird reason. I also tried resetting the PRAM but that didnt work either..
Is there anything i can do to make it reset back to where it was when i first booted after the update?
It must be done on boot.. is there a command line interface somewhere during boot i can go in and change some settings there?
Thanks for the help.

Hi and welcome to Discussions,
a PRAM reset http://docs.info.apple.com/article.html?path=Mac/10.6/en/26871.html should reset the display settings.

How to reset network settings but keep Time Machine backup data?

I am having problems connecting to the Internet through TC but works fine with Ethernet directly to the computer. I would like to wipe clean the network settings in Time Capsule but not lose the Time Machine backups. How to do this?
thanks

Just perform a "hard" reset on the Time Capsule (TC). This type of reset will not erase existing backups on the TC's internal drive.

After few second I am getting a blank page.
Please help me in configuration.

hi,
I will check for sure when I have access to the server and will write.
But I think it was under the sap.com node in the configtool. Something with uddi~ or sr~. One must search for it, then click on edit and change the configurations.

HT3255 original display settings

Simple question. How to reset display settings to factory. macair summer 2013

Try resetting PRAM as described here:

... but first, go to System Preferences > Displays and set:
Resolution > Best for Display
Brightness > (center of sliding scale)
Automatically adjust brightness = "on"

Mac Mini display settings change after shutdown

After a shutdown, my Mac Mini's display settings will change on startup. This happens about 80% to 90% of the time.
Sometimes it may be due to playing a video game (Diablo 3) where the resolution in the game is slightly lower. The Mac Mini is set to 1080p, but in-game it is 1600x900. After playing a game, maybe half the time, when I go back to my desktop, the display looks different. However, even other times even when I wasn't playing a game, after a shutdown, the display settings will change.
The strange thing is that it isn't a change in resolution. The resolution stays the same. It is always 1080p after every shutdown. But something in the display changes. Curved shaped look more pixelized, like some kind of smoothing or antialiasing has been turned off. And bright things are too bright, dark things too dark, so images lose some detail. It is also a bit painful on the eyes. Everything looks less vivid and very dull.
Someone in an older post suggested changing refresh rates. Unfortunately, my Mac Mini doesn't show that option. It was also suggested to connect to a different monitor to possibly make the options appear. But I don't have another monitor.
My current solution is to reset NVRAM (command+option+P+R) on startup. It seems to reset the display settings and fixes the display problem 100% of the time. But the thing is, I have to now keep doing this almost everytime I start up my Mac, which is annoying.
Is there a way to ensure that the Mac Mini keeps my display settings and prevent it from losing them on startup? Or perhaps, a way to reset display settings from within the OS without having to shutdown again and reset NVRAM?

hey p26grinz,
without the external monitor and after setting the display, will the setting remain ?
have you tried uninstalling the graphic driver from your unit and then testing it with generic driver ?
