Three Mac Pro Displays

Hi everyone, I have a "mid 2010" mac pro with a 5770 graphics card. I have two 22" (1920x1200) cinema displays connected now and I am trying to add a third dell 1920x1200 monitor. My problem occurs when connecting the third display - only 2 seem to work at once. What do I need to do to get 3 displays working? Thanks in advance.

Two articles you should read when considering adding 3 monitors to 5x70 cards are the following:
Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections

You can use the two graphics cards, but it's only useful if you have more than two displays. It won't give you higher speed.

Why no controls on My Mac Pro display for the 9/12 event?

Why no controls on My Mac Pro display for the 9/12 event? I thought it odd that I had no conrols for the event (later in the day) - Just something Apple was trying different. - It was frustrating that I could not pause it , and later, jump to the point where it crashed. (anybody else have that problem?) But later I had my wife look at it on her 24" iMac, and the controls were present and it worked fine. I thought it might be because I had turn off Java; I turned it on and tried it, still no fade in on mouse move controls. Anybody have an idea why? (Apple STILL needs to update the product list on this submit page This is ML 10.8)

After 3 more days, and a reboot, still no controls on THIS video. Everything else seems fine. Even the Apple movie trailers with the same type of "floating" controls work properly. Does anybody have a clue?

27" iMac as Mac Pro Display?

I currently use the 24" LED as a display for my Mac Pro, but give the increased pixels on the 27" iMac and it's MiniDisplay Port in capability, and given it's cheaper than the 30" cinema display, with a much better panel, on only slightly lower vertical display resolution, I've been giving serious thought to switching to the baseline 27" iMac as a display.
A couple things are holding me back. I'm guessing with MiniDP in, you only get the video, no audio like on the 24" LED (which uses USB). Since there's no USB, I'm also guessing there's no iSight pass-through. I could always add speakers and and a mic/cam combo, but that seems less elegant.
Has anyone tried the 27" iMac as a Mac Pro display? If so, please let me know how well it fits.

Hello Pete.
Search your SnowLeopard Mac Finder > Help for "target display mode" (without the quotation marks) to find the instructions for this new feature.
Among those instructions are:
The external display computer works like any other external display. To change display settings, open System Preferences on the primary computer and click Display.
I looked for the web-based page, but I could not find it, so, at least for now, you will need to view it in your Mac's Help viewer.

Mac Pro display remains black after start up.

My 2008 Mac Pro display remains black after start up. It is plugged in properly and the light comes on, but the screen stays black. It first started doing this about a week ago, but after a manual restart or two, it would start up properly with the display working. Today the display has remained black every time I've tried to start up. Any suggestions for troubleshooting would be greatly appreciated! Thanks!

Safe Mode uses a very simple way of talking to the screen -- it does not even load the screen driver, and it uses a very common low resolution.
If it does not work that way, it simply does not work. You need a replacement graphics card.

Mac Pro Display Issue

Mac Pro Display Issue - Unexpectedly Sleeps and Freezes
Just since a couple of days my Mac Pro desktop has been having display issues. Unexpectedly the screens go into sleep mode, it turns black and freezes, the computer doesnot respond to the keyboard or mouse.
At first I thought this was related to Chrome, and switched to Firefox, but the computer is still having the same issue. I have to shut down and restart each time it gets stuck.
I even went into preferences and changed the energy saver settings to "Never" allow display or harddrive to sleep. But this problem is stil happening.
Does anyone have the same problems? Or a solution?

I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
So I followed your advice and installed:
Temperature Monitor
http://www.bresink.de/osx/TemperatureMonitor.html
Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.
Then I installed:
smc fan controller
http://www.macupdate.com/app/mac/23049/smcfancontrol
and increased the memory_cpu fan speed which lowered the temperature of the ram to 60'C (143'F).
I even changed this ram's placement and put it in different slots.This ram was the same temperature in the new placements.
Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
Thank you for all your help!

Mac Pro display does not recover from sleep

Hello,
I have a Mac Pro Mid 2010 with two graphics cards (ATI 5770 & nVidia Geoforce GT 120) and three displays. After intense use of the GPUs with graphics processing jobs, and after the screen goers to sleep, they do not recover. The computer is accessible via the network (ping, ssh, etc) however, the screens blank out and no longer recover from sleep. The only resolution is to reboot.
I have already run memtest all just to make sure there isn't a memory issue. All tests passed. Also, this issue has ocurred with Mountain Lion and Mavericks.
Does anyone have any suggestions or experiences with regard to this iussue?
Thanks

Update -- I now can reproduce the issue at will and it is definitely related to the sleep feature and has gotten much worse under OS X Mavericks. Side Rant -- First let me note how disappointing Mavericks is as a platform. Apple's output seems to be getting progressively less thought out, reliable and buggy.
Now back to the issue. I created a hot corner that puts my display to sleep. Every time I active the hot corner the system display is lost -- that is the system continues to function and respond via network (ping, ssh, etc) but no joy on un-sleeping the displays.
I have Mac Pro Mid 2010 w/ 2x 2.4Ghz Quad Core, 32GB RAM, ATI 5770 and NVidia Geoforce GT 120 using three displays (2x 27" Apple and 1x Panasonic 1080P HD TV) running OS X 10.9.1 (13B42).

Mac Pro Display Issues

I am trying to use three monitors with a Mac Pro with a default Radeon 5770 graphics card, but I am coming across many issues. First, I had to find out that you needed two dual-link DVI adapters if you want to add three monitors. After purchasing one adapter from StarTech for a 30" Dell monitor however, the display is having many issues.
When I first turn the computer on, the display shows "snow". I have to turn the display on and off, but sometimes even this does not get rid of it. Also, the screen will not wake up when the computer wakes up from sleep, although the other DVI monitor attached works perfectly. Finally, the screen will often go into periods of complete black. I can still move the mouse on the other screen, but it jumps around and skips when I move it.
If I want to resolve this issue, should I:
1) Go with Apple's dual-link adapter instead of the StarTech one I am currently using
2) Upgrade the Mac Pro graphics to either the dual 5770 or the single 5870
3) Replace the large dell monitor with an Apple Cinema Display
Or, would none of these solutions even help if this is an unsolvable problem.
Any advice would be greatly appreciated.
Thanks!

That is not quite right. Strictly speaking, it is not three dual-Link adapters that are required, but all adapters must be ACTIVE, POWERED Adapters.
Apple's solution requires their Daul-Link adapters because those are the ones with a USB lead to pick up even more power.
Your initail query tlaks of wanting to connect three monitors, but you have only provided connection details for two.

My Mac Pro display setup for photography

I am a photographer and a recent refugee from Windows. I’m using my new Mac Pro to manage and process about 100K images and other digital assets. I’m especially pleased with my system’s display configuration. Here is what I’ve got:
I’m driving my displays with the NVIDIA GT 120. My main image viewing display is a 21” Eizo Color Edge LCD (CE210W). It has a wide color gamut and is more than adequate for my needs. I wanted a second display but was leery of the Apple Cinema units – a lot of comments on this forum and other places seemed to indicate a lack of quality control. Nevertheless, I got the 24” Apple Cinema Display and it is working perfectly.
I calibrated both units with the i1 Display 2 monitor calibration hardware. I ran the i1 Match software for calibrating the Apple display and the Eizo-supplied software for calibrating the Eizo (it stores calibration settings in the monitor’s hardware).
Opinions about monitor calibration settings are like belly buttons – everybody has one. Here are mine:
white point – 6500 K; gamma – 2.2; luminance – 120 CD sq. m.
With both monitors calibrated using these settings, my standard reference image looks practically identical on both units. That is reassuring.
I do not doubt that some people are having problems with the Apple Cinema display. But mine is working perfectly… so far. It is an essential component of a very nice system.
BTW, if you want to hook a 24” Cinema Display to a Mac Pro then you will probably need a display cable extension (Apple picked a curious way to cut costs). I got my cable extension at MonoPrice.com for $6.

Make a "Genius" appointment at an Apple Store to have the machine tested. Back up all data before you go.

Early 08 Mac Pro display black on start up!

Hi
I have an early 2008 Mac Pro with what looks like a faulty ATI Radeon HD 2600 XT.
There has been a longstanding issue with my 30" Cinema Display going blank (black) during a restart. It happens about halfway through startup when the spinning wheel is on screen. The white LED on the display lights solidly. The Mac appears to boot up normally and I can shut it down blindly using key commands.
Occasionally, unplugging the display and then re-plugging it brings it back to life but animation such as Dock magnification then becomes very jerky.
I've zapped the PRAM, reset the SMC numerous times. Both have occasionally bought the screen back to life but the problem has always re-occured. I've removed the graphics card, cleaned the connectors and then replaced it.
The issue has remained through a complete reformat and installation of Leopard and then Snow Leopard plus numerous OS updates.
The Mac almost always starts up normally first thing in the morning. The problem seems to get worse throughout the day, i.e. the longer the Mac has been on, the more likely the graphics are to fail on restart suggesting an overheating issue perhaps?
I would send the Mac in for repair BUT... it is stuff full of 3x Pro Tools PCIe cards and I REALLY don't want take them out OR send it in with the cards in place. (Please note: the problem was occurring long before the Pro Tools cards were installed.
So... my question is, does this sound like a faulty ATI Radeon HD 2600 XT? If so, I'll try and get a replacement. (Any idea where in the UK? I've searched everywhere!)

Your Mac uses a default setting to fire up the display and set a start-up picture. Halfway through the boot-up process, it switches to the stored System Preferences. This file may be damaged. A re-install (keep my preferences) would not fix it.
I suggest you boot up in safe mode (hold down the shift key all the way through startup) and use System Preferences > Displays
... to change something about your display, so that it will re-write the Preferences files.

Mac Pro Displays 2013

I have a new Mac Pro on the way. How exciting. Any way I currently have a 2012 Mac pro with a 5870 and a gtx 120 in it. It is currently driving a 46 inch tv using vga. I also have a 21, 24 and 27 inch displays plugged in using dvi. My question is will this work. If I use 1 minidisplay adapter to dvi for the 21 inch display and than I use 2 active minidisplay to dvi to drive the 24 and 27 inch displays can I still use hdmi to drive the 46 in tv hooked up.
Thanks for any help.

This article touches on the subject, but does not say you can use additional ACTIVE Dual-Link DVI adapters beyond one non-Active plus the HDMI port. The Mac Pro cognoscenti believe you CAN, provided any additional adapters are ACTIVE adapters.
Mac Pro (Late 2013): Using multiple displays

Newest Mac Pro: Displays How will 4K be displayed? : 4K 3840x2160 UHD 4096x2550 Where as: 27-inch Apple Thunderbolt Display=2660x1440

How will 4K be displayed? :
4K 3840x2160
UHD 4096x2550
Where as:
27-inch Apple Thunderbolt Display=2660x1440

4k is the generic term for resolutions that have a horizontal number of pixels around 4000. The two most common resolutions are Ultra Hi-Def (UHD) and Cinema 4K (C4K). The first is 3840x2160 and is exactly four times the resolution of "Full HD", or 1080p. The second is 4096x2160 and is one of the "standard" resolutions used in digital cinema projection.
The HDMI 1.4 standard supports both of these, but only at certain refresh rates. UHD, being the consumer version, is supported at 24Hz, 25Hz, and 30Hz; C4K is only defined for 24Hz since most of the material is going to be film-sourced. (This implies that 25/30Hz will include TV material at half their original rates of 50/60Hz.) Over HDMI, all four of these timing formats run at the same clock rate (297MHz, ignoring the fractional versions). This is the highest clock used in this version of HDMI, although the standard allows up to 340MHz. (There may be PC timing formats between 297-340...)
Using generic terms, we call these modes "UHD30" to imply resolution and refresh rate, and if a TV supports UHD30 it will always support UHD24 (although it is not a rule, merely a reflection of reality). A TV can only support C4K24 in 1.4, but it doesn't have to. There are many TVs that will support UHD24 or UHD24-30, but not C4K at all. So the practical limit of HDMI 1.4 is "up to 4k30."
HDMI 2.0, which the Mac Pro does not have [yet], provides dot clocks up to 600MHz (although above 340MHz, they are all divided by 4) and allows "up to 4k60" for pixel encodings of RGB444, YCC444, and YCC422. The new standard also allows 4k50/60 to use YCC420, which sacrifices some color information (known as 'uses chroma subsampling') but allows the data to be transferred at the same rate as 4k30. While "fine" for video--since it was probably delivered over BD/DVD or streaming at YCC420 to begin with--it is not fine for you computer's output.
I just got a 4k TV because I was tired of my dual 1920x1200 DisplayPort monitors after coming from the original 30" Cinema display of 2560x1600. Specifically, I used to enjoy >1080 pixels tall. But here's the problem with the 4k TV: while it has HDMI 2.0 inputs, the MacPro has only HDMI 1.4 so the output is limited to "up to 4k30". Moving the mouse is laggy and not smooth as it would be if the display were 60Hz. Furthermore, the MacPro is not offering me a choice between UHD or C4K--both of which the TV supports--and is instead defaulting to the largest resolution of C4K. This means the refresh is only 24Hz. And that's why I'm in the forums today--to see if there's a way to get my output to be UHD, but at 30Hz.
In a couple months, several companies will be selling DP-to-HDMI2 dongles that will support 4k60. So I am holding my breath until then.
Now, to specifically and accurately answer your question: Out the current MacPro's HDMI 1.4 port, you will get the highest resolution your TV (called the Sink) will support. If your TV has C4K24, then that is what will show up. If your TV does NOT have that, but has UHD24-30, you SHOULD get UHD30. If your TV ONLY has UHD24, then that's what you will get. If you get a TV, the chances are really, really good that the panel will have 3840 pixels across and 2160 lines down. In this case, you want the Mac to output that resolution and put the TV into pixel-for-pixel mode so every input datum is mapped to a single display element. Since most displays overscan, the Full mode will expand the incoming data from 2-5% which can eliminated the crispness (and also cut off the extremes of the Desktop). Also, if you are outputting C4K (like I am) AND you have switched to P4P mode, the horizontal dimension is shrunk by 6.6%.
If any of this is unclear, just reply. But I will say that this 40" TV is really useful, and once it is running at 60Hz...bellisima!

Better Mac Pro display: Apple 23" Cinema HD or Dell UltraSharp 2407WFP?

I bought a Mac Pro a few months ago and want to upgrade my monitor. I'm currently using (via an adapter) the 17 incher that came with my old G3. Compared to the 2407WFP, Apple's display is an inch smaller, about $300 more (with applicable government discounts), with a 3-year warranty as opposed to a 5 year warranty with Dell. Anyone have any recommendations based on personal experience?
I am using the base level Mac Pro graphics card. I'm not a gaming fanatic though I'll probably play some on the Mac (as soon as Intel compatible versions come out). Mainly interested in using my computer for graphics and music.

Glenn,
This question has been discussed many times in this forum.
Search this forum for:
"2407WFP"
"2005WFP"
"Dell"
"UltraSharp"
and you will find many answers.
The really short answer is: some like Apple and some like Dell.

These are both slightly cheaper than the Thunderbolt Screen from Apple which Ive had and loved.

Hi there,
According to the tech specs, your computer has a Mini DisplayPort that supports DVI and VGA ouput with the use of an optional video adapter. With that being said, the computer should be able to output video to monitors that support either DVI or VGA input. You can find a few of the Mini DisplayPort adapters in this section of the Apple Online Store.

Mac Pro Display Issue HELP!

Hello Everyone,
Lately i just bought a new mac pro. recently i have been doing some video projects in final cut pro 7 (i know its outdated lol) in the video preview it seems that the video has some distortion to it, meaning the the video has a skewed effect to it of some sort. I upgraded from a 2009 iMac which i have never noticed this issue before! I don't think that it would be a hardware issue.. heres my specs:
3.33GHz 6-core
12 gigs of ram
ATI radeon 5770 1gb ram
Monitor: Samsung SyncMaster SA300
I think that it may be the monitor.. as i soon plan on upgrading to a cinema display.
If anyone has and idea what may be causing this unusual issue that would be greatly appreciated!
Thanks in advance!

I cleaned out my mac with compressed air, it was dusty, but the display flickering happened again.
So I followed your advice and installed:
Temperature Monitor
http://www.bresink.de/osx/TemperatureMonitor.html
Which showed that my memory module 1B and 2B were 70 - 75'C(160 -167'F). There was no reading for the graphic card so I couldn't tell if that was over heating.

Also this is the kingston 2gb ram without heatsinks. Ive used it for 1.5 yrs, and this is the first time its giving me these problems.
Do you know how I can check if the graphic card is over heating? or is the problem just with the ram?
