When connecting my Mac Pro to an Acer monitor, the signal is not stable.

The signal switches to static about every other second.

Is that the 5770 card?
And what interface are you using? 15-pin 3-row Analog VGA? DVI? DisplayPort?
And what adapter are you using?

I cannot get both monitors to work when connecting my MacBook Pro to a VGA monitor using Mini DisplayPort to VGA Adapter

Need help with 2 monitor set up on MacBook Pro.

I am sorry for the confusion. The reason I asked about the speaker bar is that I can't find any information that shows built-in speakers on your monitor. I have looked everywhere, including in the HP specifications.
Here is the Back I/O panel (Input / Output) for your computer:
Figure 2: Back I/O panel
1 - Video Graphics Adapter port
2 - USB 2.0: 4
3 - RJ45 Network (LAN)
4 - Audio: Line in
5 - Audio: Front speaker/Line out
6 - Audio: Microphone in
The way that I have always connected speakers is to the port labeled # 5 (Audio: Front speaker/Line Out). This port allows sound to be sent to speakers. The VGA port is for video only. There is no audio capability. The only connection that sends Audio and Video is the HDMI (High-Definition Multimedia Interface) connectors.
This is the type of connector that I would expect to see coming from your speakers:
The male one at the bottom of the picture.
Please check the monitor carefully to assure that there are actually speakers built-in. I just don't want us to continue fighting a problem that doesn't exist. There may have been some incorrect information in the advertisement that you read.

My external monitor flickers intermittently and wont function when connected to macbook pro

Hello everyone,
I recently purchased a cable to convert the thunderbolt/miniport to the VGA input on an external monitor I have had laying around for a few years. I am currently running osx 10.7.5 on a macbook pro.
When I plugged the cable to connect my macbook to the monitor, the monitor certainly recognized the cable, but the display would not do more than flicker in and out intermittently when connected to my macbook.
I have searched the forums for a solution to this, but haven't been able to find one that works. I tried resetting the SMC and restarting while holding cmd+P+R but none of these "fixes" seemed to help.

Simplest thing to try is a PRAM reset.
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

Cannot connect from Mac Pro late 2013 to Macbook Pro

Cannot connect from Mac Pro late 2013 to Macbook Pro . I have tried via ethernet and wifi. I can connect from the MBP to the Mac Pro but not vice versa. I have tried to connect to other MBP's on the same network with no luck. I try and connect as a registered user, as I usually do, with no luck. When I enter the Username and then Password the box vibrates as if the details are incorrect, they are not however.
Thanks in advance
Jeff

It is 'just not working' again.
To answer you question. Other sharing services work. I can connect as a guest. I can share screens. I cannot air drop.
I cannot connect either way now i.e. from Mac Pro to MBP and vice versa.
I cannot connect to my wife MBP either. My wife cannot connect to my Mac Pro.
It neither works with wifi or ethernet cable.
I can connect to my Time Capsule directly and Time Machine backups are working.
The passwords are 100% correct.
The Mac Pro is a late 2013. Does anyone else have a similar problem? I have never suffered this one before. Seriously effecting my workflow
Thanks

Time capsule - use as wi-fi connection for mac pro to the internet

hello
i recently purchased a mac pro 2.8/ 2Gb/ 320 HD
it did not come with a wireless card.
today i bought a time capsule and want to use it to connect my mac to my wireless internet connection from my modem (dsl) via the time capsule. i have connected the time capsule to my mac via ethernet.
the internet is not working. can anybody help me please?
i have managed to get the ethernet connected and active.
when i look at "network diagnostics" ethernet is green, network settings is green and isp is green. but internet is red (failed) and service is red.
please help

i will have to use an ethernet cable between the modem and the TC, right?
Yes. It sounds like your modem is actually a combination modem & wireless router instead. Unfortunately, creating a WDS between this device and the TC will be unlikely successful ... so the only alternative (without buying anything else) would be to connect the TC to the modem via Ethernet.
this is frustrating as the apple store i bought the TC from in Osaka, Japan, would not sell me an airport card to install myself.
I believe this is because the AirPort card for your model of Mac Pro is not considered a User-installable item by Apple. I'm surprised they didn't offer to do the install for you.
then, as a solution said that i could use the TC to do what i described above.
Although they were partially correct that it can be done with the TC, it appears that they didn't provide the complete picture on how to do it.

Hello, I have a Mac computer with NVIDIA 750M dedicated graphics card and monitor EIZO but the problem was there when I was working with Windows and Acer monitor. When I open a file from Camera Raw in PS this is smaller than the screen so I double-click with the tool "hand" to fit on the screen, but the picture loses sharpness and becomes blurry. If you magnify the image even only slightly with the tool "zoom" the picture comes back clear. In Camera Raw instead is always sharp. I solve the problem by turning off the graphics card in PS but often use plugin that need the graphics card otherwise the processing time is much longer. I ask for help.
Thanks.

HT201262 screen on the TV flickering purple when connecting mini mac to TV through HDMI

anybody come across a problem with the TV connected to Mini mac, when i connect my HDMI cable to my TV and open up safari click onto Apple.com watch a video on their home page in full screen the screen flickers purple any ideas what could be the problem.

Hey there Daza2014,
It sounds like you are having some graphical issues with an TV connected to your mac mini. I found this article for you to help troubleshoot what you are seeing here:
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
This section in particular:
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart 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 best,

17inch Studio Display - What Cable to connect to Mac Pro?

Hi Folks:
I just got a Mac Pro with a 23" cinema display, and an ATI X-1900 card, but I also have a 17inch Studio Display that I was using with a G5. Which cable adapter do I need to connect the 17inch display to the Mac Pro as a second monitor?

I have the 17 inch studio display connected to my Mac Pro (X1900) via the ADC to DVI adaptor. It sits next to a 23in Cinema HD Display. If you do this be prepared for the rather shocking difference in display quality. I hardly ever use the 17in because I can't stand to look at it compared to the 23in. You probably are better off getting a newer cheaper monitor rather than spending $100 bucks on the adaptor.

ESATA: connecting 2 mac pro's via esata to each other

has anyone tried to connect 2 mac pro's via esata directly to each other (instead of the slower ethernet connection)? i was hoping to install esata cards into the pci-express slots into 2 mac pros and instead of the usual ethernet connection between the 2 so they can file share, i was hoping for a faster estata connection if that is possible. would i see the computers in the usual finder window under "shared?" note: the mac pro's would be physically close to each other, so cable length connection is a non issue.

Hopefully no one would try this.
NAS or FiberChannel like Apple did with XRAID.
OS X client is not designed to handle file-locking and device sharing, not in this manner.
Linux or HP type media servers
