Hey there George,
If I understand correctly you are seeing a couple graphical issues after upgrading to Yosemite. I would use these troubleshooting steps specifically from the following article, named:
Apple computers: Troubleshooting issues with video on internal or external displays
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
Thank you for using Apple Support Communities.
All the very best,
Sterling

My Mac Pro starts up when I turn on the power, BEFORE I switch it on with the button, why? Plus, my computer keeps freezing and blacking out.

My Mac Pro starts up when I turn on the power supply (when I plug it to the outlet), BEFORE I switch on the button on the computer, why is this happening? Plus, my computer keeps freezing and blacking out and I'm forced to restart it, that's when the compter starts on its own when I turn on the power.

Hello Engender,
I should have followed up with a progress report because I eventually eliminated all the problems I was having with my Mac Pro, now it's behaving like a new computer… beautifully. I did originally take Grant's advice above, changing the setting that I had in the System Preferences > Energy Saver but that only stopped from rebooting on its own when I shut down my Mac properly. Otherwise it continued to restart on its own after freezing or crushing when I switched on the power. I took my machine to the Apple Store and after many tests they couldn't find anything wrong with it. I was very depressed about the whole business.
It was after going onto many of the other Apple related websites that I discovered that it wasn't a faulty power switch or fan, as as I originally thought, but found out that my problem was related to the Graphic Card and possibly I did not have enough ram (I had the original amount of 2 GB). The original card that came with the computer: 512 MB ATI Radeon X1900 XT was over heating and forcing my machine to shut down, I think it was because I had upgraded to OSX Lion which on its own requires at least 2 GB of ram to operate well. I added 4 GB of Ram to the 2GB I had (4GB kit (2GBx2), Apple 240-pin FBDIMM, DDR2 PC2-5300 upgrades for Apple Mac Pro (4-core) 1st Gen. - 2006-2007 Desktop/PC, CT579443 from Crucial.com about $160 for the set) and replaced the Graphic Card with ATI Radeon HD 5770 1024 MB from Apple (around $260), (ATI Radeon HD 5770 Graphics Upgrade Kit for Mac Pro (Mid 2010) - Apple Store (U.S.)) This card works very well with my original Mac Pro 2008. I installed it about two weeks ago and no problem with it starting on its own, over heating or freezing. OSX Lion works well and I'm thinking of upgrading to Mountain Lion once I learn that my Mac Pro 1.1 will work with the new hardware I installed.
Your problem could just be the power cord but I agree with you that doesn't sound right, when I mentioned faulty switch I meant the part where the power cord meets the power button, the unit which houses the power distribution, I thought at first that it could be faulty but changed my mind because of the computer overheating.
I don't know if this is of any help to you but I hope your trouble will be solved with the new cord.

EMac screen shivers and blacks out. HELP!!!!

i bought my emac in november of 2002 and its had the "raster shift" for a few years. it is only a few digits away from the recalled numbers. it is out of warranty and genius bar said it was a logic board problem. PLEASE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
eMac Mac OS X (10.2.x)

I brought it to the Applestore. They did the repair, and since it was under warranty, It didn't cost me anything, but they did give me an invoice which showed what it would have cost had I to pay for it.
Sorry it's been so long, I've been negligent in checking my posts.
Good Luck!

How do I get rid of random screen flicker and black screen when using a late 2013 Mac Pro with a 4k Samsung 55" Display?

I have a new Mac Pro late 2013 and a 55" 4k Samsung display connected using an HDMI cable. For the most part the display is amazing, however, I get occasional screen flicker and black outs. Can anyone help? Could I possibly have a bad video card?

4K displays take more than half the bandwidth of a ThunderBolt Bus. So you may get better results if you are careful to place them on their own Bus. This article has the explanation of which port is using which Bus:

Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Reset all settings
Go to Settings > General > Reset and tap Reset All Settings.
All your preferences and settings are reset. Information (such as contacts and calendars) and media (such as songs and videos) aren’t affected.
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store.

While using Skype on my mac pro the screen freezes and splits in two and the left hand side shifts to the right and the right shifts to the left with a large black block down the centre, should I take it back to store as it is only a month old??

I have only had my mac one month and it seems while I use Skype the screen freezes and I cant click on anything and everything on the right hand side of the screen shifts to the left and the left to the right with a back block down the centre and sometimes lines running down the screen over all. As it is almost brand new should I be going back to store to get this problem fixed??

Yes. You are still under warranty. Why waste it?

How to fix my iphone screen because it blacked out and it still works

how can i fix my iphone screen .
It blacked out but my phone still work help!!!!

Hi zhamond,
If your screen is black but the phone appears to still be responding, you may have inadvertently activated a feature known as Screen Curtains (part of the Accessibility functions). You may find the following information from the iOS manual helpful (pg 126):
Turn the screen curtain on or off. Triple-tap with three fingers. When the screen curtain is on, the screen contents are active even though the display is turned off.
iPhone User Guide For iOS 7 (October 2013)
http://manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf
If the phone isn't responding or simply won't turn on, then this article may be more useful:

My iMac screen freezes and a grey colour slowly creeps down my screen

Hi, my iMac screen freezes and a grey colour slowly creeps down the screen and has a large black square in the centre saying "You must restart your computer by pressing the power button and then pressing it again to restart" or words to that effect in English and about 4 or 5 other languages. I find this happens more frequently when I try to stream movies or tv shows. It also happened when I was trying to download a couple of tv shows from iTunes.
It also sometimes makes a wierd sound a kind of loud noise like a record stuck in a groove. This has happend many times since upgrading to Lion. I hear a lot of people on here talking about their screens going completely black and not responding. I believe that mine has only gone black a couple of times and I couldn't wake it up from "sleep mode" with the mouse or keyboard. I don't know if this is also happening to other people, but my bluetooth keyboard keeps disconnecting all the time since the upgrade as well, it's driving me nuts!! Plus my wifi will show that it is fully operational, however, I can't use the internet when I wake my computer from sleep mode. I have to click on wifi and turn wifi off then on again before i can use it.
Is Apple going to come out with a fix or are we going to eternally suffer indefinitley.

Hi Eric,
I don't know why it didn't work before, but here is the most recent errol log. It crashed again about an hour later. If there is a solution, i would greatly appreciate knowing what it is because I can't enjoy using my computer anymore because of these constant crasahes.
Thanks for your time.

Playing music the screen freezes and if i want to make changes it will not let me.I go to restore factory settings and afterwards i am able to listen,view album covers,and change the type of music i want.Is there a better way to do this? Thx

When playing music on my ipad the screen freezes and i am not able to view album covers or make any changes i am only able to hear what i selected.
This is the third time it has happened since i updated to the new IOS 5.1. It never happened before.
If i go to Summary and restore the ipad to the factory settings then i'm able to run it as normal.
Is this a glitch in the new software,or a problem with my ipad?
Thanks for any help

Thanks Russ H and Ross H!
I'm finding Multicam, combined with Compound Clips to be extrememly efficient.
I started with 2 different video clips, along with 2 different audio clips.
Layed out both clips side by side (visually, they are on top of each other on the timeline),and made that a single compound clip.
Then I laid out both audio clips on top of each other on the timeline and made those a compound clip.
So now I have
2 original individual Video shots
1 compound video shot of the 2 above side by side.
2 original audio tracks
1 compound audio track
Next I made a multicam track, and added to it all 3 video shots (2 original + 1 compound) And I added the compound audio track. I set that audio track to be "the" track.
It's just a little bit of setup, but really not that bad, and the ability to use the multicam feature to switch between shots, while keeping everything in sync is fantastic!

Photoshop Creative Cloud flickers and blacks out

I posted this in the Creative Cloud forum, but was told to post it here.   I am sure it is only a Photoshop Creative Cloud problem.
I am using Photoshop Creative Cloud, on trial. I have been using Photoshop, desktop version, for 20 years. Never saw this problem on it.
PS CC flickers and blacks out. Many times, many different files, many different actions cause this.    Right now, I am editing a photo, and using the Magic Wand tool to select areas that I will remove from photo.   PS CC is flickering on my screen, on/off.    Sometimes it goes completely black.
I can see the menus, but the image itself is flickering on/off. Mostly off.
Thanks

Yes flecking is a common problem. If happen for many bugs. That is why I posted the search instead of trying to answer your question for you posted little information bout your problem. In the guidelines you will see
=============================
Supply pertinent information for quicker answers
The more information you supply about your situation, the better equipped other community members will be to answer. Consider including the following in your question:
Adobe product and version number
Operating system and version number
The full text of any error message(s)
What you were doing when the problem occurred
Screenshots of the problem
Computer hardware, such as CPU; GPU; amount of RAM; etc.
=================================================
Information like that help to identify if you have a known problem from what your using and help pinpoint where the problem may be .   Even if you have the latest OS it its updates. The latest video driver and the latest Photoshop update does not mean you will not have any software and hardware bugs. Just because there have be problem reported about flecking in Photoshop in all supported Platforms OS versions does not mean that there is a single common problem in Photoshop. All it means is that flickering is a common side effect caused by bugs.

Gateway DX4840 is Experiencing Screen Freezing and Crashing

I am running Windows 7. This problem started about three weeks ago. Occasionally the screen freezes and nothing will unfreeze it except a cold boot. Control-Alt-Delete does nothing. Sometimes the screen goes black. At other times the screen shows
an odd multicolour pattern. Occasionally the computer crashes altogether.
I can not seem to find any hardware problem. Sometimes the computer will run for several days with no difficulty. There is no sign of a virus. I have checked my C drive for problems and found nothing.
I normally run Chrome and sometimes Chrome and Explorer at the same time. Has anybody experienced this problem.
Thanks very much.

Hi,
Firstly, please check the issue with the method below:
Windows hangs or freezes

Meanwhile, I think you need also to check the hardware side; please ensure all the drivers are up-to-date and you can also contact Gateway support for help.
Thanks.

My screen just randomly blacked out on my iphone

My screen just randomly blacked out on my iphone. It still rings when someone calls, and hold the two buttons together doesnt do anything... the screen just stays black... So cant unlock and I cant sync to my computer since the screen is black... HELP!!!

Hi snwbuny721,
If your screen is black but sounds still work and your phone still appears to be responding, you may have inadvertently activated a feature known as Screen Curtains (part of the Accessibility functions). You may find the following information from the iOS manual helpful (pg 126):
Turn the screen curtain on or off. Triple-tap with three fingers. When the screen curtain is on, the screen contents are active even though the display is turned off.

If you just got it back and it isn't fixed or something else is wrong with it take it back and have them do the repair correctly.

My secondary monitor flashes and blacks out after the 10.7 install. Any ideas on how to fix this?

I have installed 10.7 and the secondary monitor flashes and blacks out. I downgraded back to 10.6 and the problem went away. I reinstalled 10.7 and the same problem happened again. The monitor blacks in and out especially when the pointer is placed in the dock area, but it still happens all the time. My secondary monitor is a ViewSonic 22 inch that is connected to a DVI to display adapter. Any solutions??
Thanks

Talked to AppleCare and it's most likely the fact that my MacBook has 3.0 USB ports and my non official charging cable can't support that. So yeah, I'll try a new cable, hopefully that's the fix.
