OS X :: Unable To Connect To HDTV / Screen Turns Blue With System Crash
Jul 4, 2009
The first time I connected to my HDTV using a mini displayport-dvi and a dvi-hdmi adapter, it worked flawlessly. Stupidly, I set my TV to a resolution it couldn't support. Now the screen only turns blue until System Preferences eventually crashes and the TV gets no signal.
I've tried clearing my PRAM, deleting the profile in the colorsync folder, and even deleting /Library/Preferences/com.apple.windowserver.plist out of desperation. I've confirmed that it's not a problem with the adapters by successfully getting another HDTV to work. Where could could OS X be storing the display's settings?

I have a 27" iMac and an LG 47" 1080p HDTV. I just bought the Griffin Video Display Converter, which is certified by Apple to pass both video and audio from the mini display port on the late 2009 iMacs. Whenever somebody turns on the HDTV the iMac's screen flickers the color blue on and off, sometimes staying that way permanently. Permanently the color blue that is. The only way to get out of it is to turn the iMac off and then back on (restarting it).I have the ?Mirror Displays? checkbox checked in the ?Display Preferences?. When I uncheck that box it treats the connected HDTV as an extension to the iMac display, whether the HDTV is on or off, which makes my cursor disappear off one side of the screen. This is why I leave mirroring on.

As anyone found a way to create a video playing screen saver in Quartz Composer in Snow Leopard. These screen savers work fine in Leopard but crash System Preferences when you attempt to load them in Snow Leopard. They seem to work just fine within Quartz Composer.

My Mac will freeze at random moments (not while running any particular app or program) and go to a blue screen, after a few seconds it clears up by itself. Sometimes it will happen several times in a row, sometimes 10 - 15 minutes in between.

I am on a brand new 3.06 GHz iMac. Installed Snow Leopard, 10.6.1. In general I don't experience any of the problems other people seem to have. But twice now my screen has turned blue while I am in the middle of something. All the open apps disappear and the Finder seems to relaunch. It only takes a few seconds. I don't have steps to reproduce it. Both times I had several apps open and had video/DVD running in the background.
Has anybody seen this?
I am a notorious file-saver which means I haven't lost much work through this but if it keeps happening I might have to go back to Leopard.

When I have no other internal drives connected I have no problems with Windows 7 loaded in boot camp. But when I connect my other 4 internal drives (in bay 2, 3, 4 and optical bay 6) which are set up as a Raid 0 configuration for Snow leopard I run into problems- I get a blue screen of death almost instantly when I start to move the cursor in windows 7. Seems like if there was a way to tell Windows 7 to ignore the 4 other drives then it would work fine? I don't want to have to pull them from the machine each time I start in windows 7.

I'm trying to connect my MBP to an HDTV with a dvi/hdmi cable. When I plug it in, all I can see on my my HDTV is my MBP wallpaper.
how do I do this, my display options (in the system settings) only has two tabs: display, and color.
No arrangements tab. Does my MBP have to be connected to the TV to have an arrangements option?

I've used Boot Camp to create a 32GB partition and install Windows XP (SP2 home edition) on my alu iMac (2.66 Ghz, 4GB RAM).
I used the FAT format to allow transfer of files between the Mac partition and the Windows one.
After booting Windows, I put in my original Leopard install DVD as directed, and the Boot Camp installer automatically came up.

I've got a 2007 generation Mac Mini and a 720p Proscan HDTV with a VGA input. When I hook it up and crank up the Mini, the apple logo appears (on the standard gray startup screen), but when the OS starts to run my TV loses the signal and a message pops up that says "Not Support!" How can I fix this? Better yet, can I fix this? Are they just not compatible? I ordered a DVI to HDMI cable to give that a shot, but I've got a feeling it's not going to work.

I've got my MacBook attached to my 40" Sony Bravia HDTV (KDL40W4500), and when I mirror the display or use the HDTV as the primary screen it cuts off portions of the screen like the main toolbar on top, as well as some of the dock. I tried to change the Screen Format on my TV but that doesn't seem to work, does anyone know how to fix this?

I have a friend who's mac has corrupted files and no longer boots. What is the best way to recover any data or backup the drive and run a install?
Or is it possible to save his current install? I'm not sure if you could just recover using his installation disk.

So I have a DYNEX 21 inch HD TV conected up to my MBP via the VGA connection route. My problem is that when I want a program (or more specifically in this case a game) to go into fullscreen mode it automatically goes to my primary monitor and turns the other screen black. I know I can switch the primary monitor from my actual laptop screen to the TV however I just want the game to be full screen on the TV while still having access to my dock and everything on my laptop.

So I've got a powerbook G4, thats 8 days past its warranty. Conveniently, it now won't turn on. It won't wont boot from CD. If I turn it on, I get a gray screen that usually just turns my computer back off, if thats not the case I get a screen that shows the finder icon and a question mark and then turns off.
All it will do is boot into open firmware mode. Currently the install disc is inside of it and I've tried booting the cd using "cd:, bxi" and "dir hd", and it can't open both. Does anyone know how to wipe the HD, and start the installer using firmware? Otherwise, I think I'll have to take out the harddrive and plug it into an external case and then wipe it.

I have a cheap hdtv. when i connect my macbook to it it doesn't get a signal (via mini dvi to hdmi) until i click "detect displays" on my laptop, then "gather windows," then when i set the display to the proper resolution (720) the image appears on my tv without a problem.
I just got a mac mini, and since i don't have two monitors I cannot use this trick. I get no image on my tv.

On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.
I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.

I have been running low on memory space for a while and just recently I turned my laptop on and all I saw was a blue screen. Fortunately there was still a bar on the top of my screen and I was able to access Safari by selecting the apple icon->Recent Items->Safari. I still cannot see the time or any of the other features. Safari seems to be the only application I can open, my itunes won't open and neither will just about any other application.

I tried fsck -f fsck -y multiple times, booting in safe mode, zaping the pram and all that stuff, nothing as worked. I don't really care about how to fix it but I care more about, Is there any possible way I can get files off of the macbook even though it wont boot. Like is there a way for another computer (windows or mac) to pick it up so I can transfer files? What accessories will I need?

Won't boot up past this screen, this is the first time this has happened. I am fairly certain it is related to an attempt to install SP3 (I had removed it in favor if SP2 to hopefully fix some wireless issues). I noticed when I shut it down last time that it was installing updates, which most certainly included SP3, and then I left the computer. Maybe the install failed? If so, how can I fix this? Any way around other than reverting to a backup? (I think the clone I have of it has SP3 on it)

i have a daewoo HDTV and only yesterday for no reason when i plug my Macbook white 2.2 into it has this darkish blue tint appeared.... the macbook is normal while the TV has the tint.
the tv has worked perfectly before for 5 months! i ve tried different pc monitor cables.....could it be the short white MAC adapter? i have not changed any settings going into "display" and chaging the resolution/ frequency does nothing.

getting really annoyed here, installed snow leopard on 24" iMac 2.66 GHz Intel Core 2 Duo and all seems to go ok until it restarts
it just hangs on the blue screen for hours and hours, even a power off/on results in the same problem
i can boot into safe mode no probs, but always end up on hanging blue screen when i reboot (safe mode ok)
deleted all login items etc, but still no go
not running any haxies either
