OS X :: 27" Connected To HDTV Blue Screen Options In A System
Jun 6, 2010
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.

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 2010 Macbook pro and I just ordered a minidisplayport to HDMI cord. I was able to get it all set up to my Sylvania 22" HDTV HERE but I can't seem to get the resolution right. I've tried multiple resolutions both via the control panel and NVidia's control panel. Keep in mind I'm running Windows 7 via bootcamp. I'm able to get the resolution to look pretty clear, but by doing so it cuts off the edges of the screen, where as if I get it so it all shows up on the screen, it doesn't look as clear.

I'm using a DVI->HDMI cable to connect my Powerbook to my Sony LCD TV. The Sony's native resolution is 1366x768. For some reason my Powerbook doesn't want to switch to this resolution. I can get 1280x720, but this leaves a black border around the images the whole time.
I've tried setting a custom resolution using the trial version of SwitchResX but to no avail. It won't do it.
Anybody have any similar experiences and possibly found a fix?

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 am hoping someone can offer some advice/help on a fresh issue happening with my Macbook (late 2007; OS 10.5.8; 2.2Ghz Intel Core 2 Duo; 1GB memory).ll darkened/shaded areas on my display are lined in little red pixelations. It's especially bad in colored screen images/photos and the worst in videos (ie Youtube).I noticed the issue about 3 days ago (5/14), and attempted to do some different software updates. Nothing. I'm really lost. The tech guy at work (not a mac guy) said it could either be a video card problem or the display is failing. I know very little about these things, but I do know the computer is out of warranty.

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 connected my Aluminium Macbook (2008) to my HDTV via a Mini Display to HD port.This works fine when I mirror the image from my macbook. When I turn off mirror image however (IE effectively having two seperate screens) my internet slows down drastically. In some cases it also disconnects. This issue is resolved by turning on the mirror screen button, or unplugging the cable from the laptop.

I've searched online and in threads here on the "can I use an iMac as a monitor" question, and found mostly negative answers. One exception seems to be the 27" model connected via mini-Display Port.However, I'd been hoping to connect an older (G4/DVI) Mini to a new (21.5") iMac, to use the iMac as a monitor.The only semi-hack solution I've seen is to use Screen Recycler or similar software. I have two questions, though:-Can Screen Recycler be used to mirror a desktop, not just extend it? (all info I've seen talks only about extending/2nd monitor, not mirroring).
-How's the performance?

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)

Got 2011 Mac mini and connected via HDMI to 15 months old Samsung 46 inch LED TV using 1080p and 50Hz. From start (dec 2011) I have had the problem that occationally (>50% of the times) the TV starts to flicker heavily. It is "war of the ants = cannot see anything" on the TV for like 3 seconds and then I can see the desktop clearly for around 3 seconds an then it is back to the flicker.screen. It keeps on like that until I shut-down and restart the Mac mini. Sometime restart works an sometime it does not. Anyone with similar problems that know what to do?

I have an iMac 27 and I want to connect it to a HDTV samsung 46 full HD. I have conected from displayport to HDMI and i get the screen. But at the same time I have connected a 3,5 minijack from the computer to the RCA audio in of the TV but I dont get sound. I have checked the config of the TV and I dont find any place to activate it. Then, talking about the screen. I have few questions.
How can I stop the screen on the iMac and work only with the HDTV?
How can I config that the windows on the tv have bigger letters while they keep on the same way on the i Mac's screen?
The tv is kind of far away and is difficult to see the letters.

while i am using my macbook the screen will suddenly go blue and flash between different blue colors like it is trying to work. sometimes it comes back on but most of the time it stays like that. I have to force shut down with the button and then restart...about half the time it is still flashing blue after the restart and if it does work, it goes blue eventually.
dont know if its a problem with the screen or what because the computer continues to work...if there is a movie on, you can here it in the background and the screen just flashes.

I have a late '08 MBP that I'm connecting to a brand new 27" ACD (which is unbelievable by the way), and everything works great for a while. After sleeping and waking a few times, there's a massive 4-5 second lag all of a sudden only when the volume is adjusted (bluetooth Apple keyboard), and the sound is gone no matter what level the volume is set to. The sound is set to run by default on the ACD's internal speakers. Everything else on the keyboard functions fine. It's just the volume that's affected. There's no way to correct it unless I unplug all three cable connections (USB, MDP, Power) and plug them back in. If I just disconnect one (I've tried all three individually), it doesn't fix anything. Lastly, I got the updated Apple software for the monitor before I even got it home (so unless they've put out an update in the last two weeks, then I have the latest software).

I'm looking to output my mac pro to my HDTV (cheap mans video output monitor). I got a DVI to HDMI connector and all the females and males seem to agree to the point that its all connected up rather well. Only problem is that my mac pro only detects my computer monitor, not the TV that I've attached. Things to note:
* I normally run two monitors at 1920 x 1200. I just removed one and replaced with DVI > HDMI adapter going to TV.
* I can get the display to work in windows (although for some reason, although it outputs to the TV via HDMI the other screen stops working) so the connectors are working fine.
* I tried hooking up the monitor to the port, downgrade the res to something below 1080, then connected the TV again, no result!
* I couldn't get 1080 resolution on my screens as its not an option in the display preferences.
* Before anyone states the obvious (at this point even that would be helpful) I restarted every time I attached another display.
* I have searched google, apple support, and these forums and I feel im going insane.
To summarise, I haven't seen my mac on the TV yet. Its staring back at me with a blank black.

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 found out what the problem is but i'm not sure which cable to get.My TV manual says 'Connect a D-Sub cable between PC IN [PC] connector on the TV and the PC output connector on your computer" (did that part <<) and then "Connect a PC Audio Cable between the PC IN [Audio} jack on the TV and the Audio Out jack of the sound card on your computer. . The port is next to the VGA cable in the pic.

I'm thinking about buying a mac mini to use with an HDTV as the primary screen. I've read some other posts regarding this. My question is, which method of hooking the setup up (i.e., which cables) provides the best picture. I've done this with a PC before but the connection was crumby... is this the case with the mac mini? Will I be able to get the same resolution that I can in a monitor? Also, I have looked at a ton of HDTVs and find the picture to be pretty bad compared to older TVs. Can anyone reccommend a model in the $500-700 range that has a good picture.
