2nd monitor problems

I am using a Samsung SyncMaster 243T for my primary monitor and an ACER AL2051W for my second monitor. I bought a mini-DVI adapter which allows me to send a cable to my second monitor which now works. Unfortunately, it is acting strangely. When I drag something across the screen, it stutters and resists, occasionally freezing.
I primarily do video editing. My card slots are assigned: 4 for my external RAID (my editing RAID), 3 for my KONA card (video) and 1 for the NVIDIA GeForce GT 120 that came with the computer (and was already installed in the 1 card slot).
I also am finding that Final Cut Pro operates much slower on this computer than it did on my old Mac Pro which was dual-core.
Based on this information, does anyone have any idea why I may be having these problems? I was told that the next operating system and the FCP upgrade will take more advantage of the 8-core processors, but it still strikes me as strange that my new computer is slower than my old one in the key areas of my business.
Thanks.

Wish I could move this to the "Displays" section, so pretend it was, and look in there, and it sure seems like
Not all monitors take kindly to the adapters, especially 3rd party
There have been a number of problems reported with Dell, HP, Viewsonic and other monitors with the 2009 and display adpaters
Not all DVI adapters are built the same
The GT120 seems to have trouble with two displays
As long as you came from Mac Pro (2006-7?) and not a G5, it should be safe and work fine even if you used Migration Assistant.
Then hope that your external RAID (my editing RAID - +what make?+ ), 3 for my KONA card (are all 2009 / 10.5.7 happy and compatible.
You could try one by one working with one monitor only, no adapter and see how that performs, then swap to other monitor and using an adapter. After that, if it isn't okay, then try to see if removing KONA unless you know it is definitely not a problem based on other's reports. And lastly, that your RAID controller and drivers are up to snuff (not all are, but worth testing).

Viewer on 2nd Monitor Problem

I just upgraded FCPX to 10.06 and when I show "viewer on 2nd monitor" the image is all screwed up and distorted, almost like it lost sync. This has never happened before. Has anyone had this happen after upgrading FCPx??

I checked the connections. If I output the event viewer to the second monitor then its all correct. I've found a work around but it's very strange. I had the second monitor on top of the main monitor in the display preferences for monitor arrangement. When I move the 2nd monitor to the right of the main monitor in the preferences and quit FCPX and re-open FCPX, it then works fine. I never had this issue before I upgraded to the next version 10.06. Try putting your 2nd monitor on top of the main monitor (in the display preferences) and then output the Viewer to the 2nd monitor. Curious if you get the same problem.

HT1338 cannot connect my MacBook Air to a projector -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

Hi There,
I have had the exact same issue but with a projector.
The issue lies with Mountian Lion 10.8.2.
I tried many a combination with no luck to get HDMI working.
Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
Bought my macbook home and voila, now displaying through my projector.
There is a small graphics update after 10.8.1 which seems to be the cause.
Hope this helps.
Thanks.

Lightroom 4.2 - Experiencing problems with images viewed on 2nd monitor

Hi All,
This problem seems to have started with my updating from 4.1 to 4.2. I have my second monitor set as Loupe - Normal and Fit. As I crop an image on my main monitor, the 2nd monitor view does not always change to the cropped view. If I switch to a different photo and then back to the one I just cropped, the 2nd monitor view will then show the cropped image, but it is almost always blurry. Sometimes I can click the image in the 2nd monitor view to change to a 1:1 view and it will look sharp, and then click again back to Fit and then it too will be sharp. Other times I get a message in the 2nd monitor view that says "no image selected" and bouncing back and forth between a different image will correct this.
This all started off with the majority, but not all cropped images showing as blurred and progressed to what I have described above. I seriously though I had a focus problem with my camera!
Is anyone else experinecing this since updating? Suggestions?
Below is the suggested information to provide...
What version of Lightroom? 4.2
Have you installed the recent updates? Yes, 4.2
What operating system? Windows 7 Ultimate 64 bit
What kind(s) of image file(s)? All images are converted to .dng upon import
If you are getting error message(s), what is the full text of the error message(s)? No error messages.
What were you doing when the problem occurred? I am in the develop module cropping images etc.
What other software are you running? Silver Efex Pro 2, but I have had that installed in many prior versions of Lightroom
Tell us about your computer hardware. How much RAM is installed? 32 GB - Yes, I know - overkill...
How much free space is on your system (C:) drive? 119 GB of 223 GB of my solid state drive c:\
Has this ever worked before? Yes
If so, do you recall any changes you made to Lightroom, such as adding Plug-ins, presets, etc.? No other changes other than updating to 4.2
Did you make any changes to your system, such as updating hardware, printers or drivers, or installing/uninstalling any programs? No, no other changes.
Thanks!

2nd monitor & app problem

i copied and pasted this from another mac forum... there was no reply. sometimes i have the same problem with apps such as cdxtract, battery 3 and Kontakt 3 in standalone mode.
Not Logic related but any ideas coz this can be very annoying if i forget to drag from 2nd monitor to the mac before hand.
I have a 2nd monitor attached to my Mac and if open an app Window on the 2nd monitor the next time I start the app the Window always defaults to the 2nd monitor (even if the 2nd monitor is turned off). Since I don't always remember that the app was opened on the 2nd monitor I would like a way to force the app to default to the primary monitor so I don't always need to turn on the 2nd monitor

The second screen is an extention of the primary screen and when you switch spaces, both will change to a different space.
There is a solution, but it requires associating the app with All spaces in System Preferences > Expose & Spaces > Spaces tab > Assign the app to Every Space. Then as you can spaces that app is present on all spaces.
Regards,
Captfred
If you don't want the browser in the primary monitor for all spaces, then use two different browsers. Safari for the primary browser and Firefox for the browser moved to external display. Then define Firefox in all spaces and Safari to only one.

MacMini (2011) problem with Thunderbolt display if 2nd monitor is connected via HDMI/DVI adapter

Hi,
iam running a MacMini (2011) 2.3GHz i5 with Mac OS X 10.7.4 16 GB 1333 MHz DDR3 256 GB Samsung SSD.
If i connect a Thunderbolt display only - all is fine.
But if i connect a 2nd monitor ( Samsung S23A700) via HDMI / DVI adapter (original Apple) the major screen (Thunderbolt Display) sometimes
is going black and immidiately back to normal. It looks like that it happens very often if i scroll down with the Apple Magic Mouse.
Any ideas?
Thanks in advance
Thomas

I have exactly the same problem. MacMini Server i7 (mid 2011) Macmini5.3.16Gb ram.
Mini and Thunderbolt no blink-outs.
Mini and Thunderbolt and Dell 23" connected to HDMI-DVI connector, the Thunderbolt display blinks out when system is under stress as in the Develop module of Lightroom 4.
I thought it was a problem with my Thunderbolt display, and since its on a VESA mount, I didn't really want to haul in in to the Apple Store. I decided to be sure it was the dosplay...
I borrowed a MacbookPro i7 and ran it from a clone of my Mini. No problems aster hours of use. (But with only ONE monitor.) That suggested that there was no problem with the Thunderbolt Display.
I decided to run the Mini with only one display. Again no problems. I plugged in the Second monitor to the HDMI port and within 2 minutes I had my first "Blink-Out".
I ran the rest of the day without the second monitor with no problems.
I conclude the mini will not work reliably with two monitors if one is a Thunderbolt.
I was using two Dell Monitors before I got the Thunderbolt Diskplay (for 3 months) without incident.

MacBook Pro performance issues w/2nd monitor and FCP7

I have this MacBook Pro bought brand-new in January 2010:
Model Name: MacBook Pro
Model Identifier: MacBookPro5,2
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 6 MB
Memory: 8 GB
Bus Speed: 1.07 GHz
and until today had never attached a second monitor to it. Today I hooked up my Samsung 24" to do some dual screen editing in Final Cut 7.0.3. I was unable to play back my video at full speed in the second monitor, and after a few seconds of skippy playback I'd get that error message about unable to play back video at full speed and to check my RT settings. I was using a Mini DisplayPort to DVI adapter. My computer has no issues playing the video in the laptop's monitor at any resolution and any quality settings (I've never changed the RT settings or anything else in the menu ever but I tried every combination this time). I then tried using my TV as a 2nd monitor with an HDMI adapter. Same performance issues. I then tried my friend's newer 13" MBP 8,1 and it performed flawlessly with the same project & footage. I feel like my $3,000 computer should outperform a $1,200 one even if mine is a year and a half older. Any advice?

Wow, you posted this perfectly to coincide with an identical problem, albeit using Logic Pro 9.1.5 rather than FCP.
Last week, I purchased a 23" external monitor to use alongside my "flagship" 2011 15" hi-res, 2.3 i7 Macbook Pro with 8Gb of RAM.
It is connected via a mini-DVI to D-sub analog (not that that should matter?) and all appeared fine.
The first issue I had was with my MBP's fan now running CONSTANTLY, when I have the second monitor attached. Even when the machine is completely idle.
When using the machine to record audio, this is a fairly hefty problem and not something I had anticipated - indeed why would I anticipate such a thing?
What is far, far worse though is that over the last few days I have had repeated problems with performance drop-outs and errors in Logic and I have trying to fathom out why. Realising that the only major system change made, was the above monitor connection, I ran some tests.
I restarted my MBP, no other apps were running and with my new 23" monitor attached acting as main display with MBP built in display on as secondary
I loaded up a fairly demanding Logic project which was hitting 40% to 60% CPU usage when using the built in MBP display last week
I ran activity monitor and had CPU usage history open
The above project now repeatedly overloads and playback halts in a given 8 bar section - with CPU at 80% most of the time
I disconnected the external display, no shut down, I just let the machine switch to the built in 15".
Started the same project, the same 8 bar section and hey presto - CPU usage back down to 40% to 60%
The above was reflected in the CPU usage history with the graph showing CPU use down by about a half, when running this Logic project WITHOUT the external display.
There is a very useful benchmark Logic project that has been used as a test by many users to gauge Logic performance on given Apple hardware.
The project has about 100 tracks pre-configured with CPU intensive plugins, designed to tax the CPU.
The idea is that you load up the project with tracks muted, press play and then unmute the tracks steadily until Logic us unable to play contiunously because of a system performance error.
On my MBP, with the external monitor NOT attached, I can play back around 50 of the audio tracks in this benchmark project.
With the monitor attached, I can get about 22 tracks playing.... which is actually a far worse a performance drop (-50% I think!?) than with the first example!
I did also try with just the external monitor attached and not the MBP display and performance was about 10% better than with dual monitors - so still extremely poor, to say the least.
This machine is the flagship MBP and has a dedicated AMD Radeon HD6750 GPU which should take care of most if not ALL graphics processing - I mean it's capable of running some pretty demanding games!
Putting aside the issue of constant fan noise, there is no reason AT ALL, why using an external monitor should tax the i7 CPU this way - it's not as though Logic is graphically demanding... far from it.
I am on 10.6.8, Logic 9.1.5, all apps up to date via "Software Update".
I will of course, be contacting Apple...

2nd Monitor won't work

I bought a Pavillion p6210f last week with Win7 loaded to replace my Dell/Vista. I was using two monitors with a VGA port and DVI port on the old PC, so I tried plugging in the same on my new HP and the DVI would not fit. In examining the pins I found that, althought the Manual said DVI, but the plug has the pin/bar arrangement of a DVI-D. So, I bought a VGAto DVI-D adapter and everything plugged in snuggly. All pins and bar appear a match.
But, it won't work. This is what is showing
NVIDIA nForce Serial ATA Controller HP RC Mirror Driver [Display adapter]
NVIDIA GeForce 9100 [Display adapter]
Acer P241W [Monitor] (24.0"vis, s/n LB4040014320, March 2008)the one working monitor....
After hours with the 800 support and hours of reversing the two Acer monitors, the DVI-D port is simply dead. Anything plugged in to the VGA works fine, anything and any combination plugged into the DVI-D and cable switching etc. the 2nd monitor is not even recoginized. The NVIDIA control panel doesn't recognize it. The amber power light just stays that way and nothing ever flashes on the 2nd screen. That is, it is the same as not plugging in at all.
I was less than pleased when 800 tech and supervisor suggested I take it to a repair center. A week old? I have put way too much setup and data transfer into the new HP to go back to the retailer for a replacement.
Techs didn't know, but could there be a DVI-X with the same pins that also fits

Eldric, did you update to the latest video driver from nVidia? It sounds to me like a driver problem. Update and let us know if that solves your problem.

Mac Pro 3.1 (early 2008) lags since I connected a 2nd monitor - HELP!!

Hey guys,
I just bought a 2nd monitor and i have lags every 5 seconds which
last about half a second (feels like 10 or less fps during the lag).
It happens with all kinds of applications. It gets worse with multiple
applications openend at a time. The crazy thing is that it only occurs
when i start to use both monitors at the same time. When i e.g. use
Logic 9.1 and use one monitor everything runs nice and smoothely
but as soon as i move the window slowly to the 2nd monitor i can
see the window lagging while I'm moving it. This is really annoying
because it seems not every input from the mouse/keyboard gets
into the system and its not a smooth workflow at all.
I switched the monitors connections but it didn't help.
Mac Pro (Early 2008) 2.8Ghz 8-core
Snow Leopoard ( 10.6.2 )
6GB RAM (2x2gb kingston, and the usual 2x1gb)
ATI 2600XT and 3 HDD.
1 Monitor 24" LG W2452T running at 1920 x 1200
1 Monitor 22" Samsung Syncmaster 2243BW running at 1680 x 1050
I really hope that you guys can help me out with this one.
What could be the problem? The ATI 2600XT should definately
be able to handle two screens at once with such little graphics
in logic 9 ?!
I want to run Logic 9 and an analyzer software (Spectre from AudiofileEngineering)
at the same time but its not possible with the LAG.
The problem/lags also occur when i sync the monitors.
Would a 2nd graphics card be a solution? But as I said
before its not a graphics demanding application.
Is it a hardware or software problem?
Summary:
- The whole System lags (not just one monitor) when
I start to use both monitors (having application windows on both).
I've got minor lags when using only one display and leave the
2nd one with the desktop wallpaper clean.
I tried:
-using only the 2x1 GB RAM which came with the mac pro
-using only the 2x2 GB Kingston RAM
Thank you in advance for your help guys!
Rick

Hey all,
I wasn't able to fix this yet.
I did everything I can think of. I even tried to wire
one monitor with a VGA cable but it didn't help.
I even have small lags when I am moving the Safari window
between the 2 monitors. Really little lags then but they
definitely are noticeable. I can make a video of that
if that would help someone understanding.
Hope there is someone out there who can help me with this.
Thanks already for any advice!
Cheers,
Rick
Edit: Do you think a new graphics card like the ATI 4870 would
help it? But I really don't want to spend more money just to
have 2 monitors while i have already 2 dvi connections on the
ati 2600XT.

2nd Monitor

2nd monitor switches itself off after approximately 30 minutes and then goes on/off intermittently every 10 mins.
No particular pattern, but wonder whether heavy graphics work in Photoshop CS4 is a pointer? Unable to use the EIZO monitor for work.
All cabling good. No problem with iMac 20"

2nd monitor W2072a suddenly has no signal

2nd monitor W2072a suddenly has no signal, tried switching cables & rebooting but box comes up states Scanning then No Signal. I desperately need help since the only way I can use a computer is with 2 monitors due to a disability

Hi ToniClark,
Welcome to the HP Forums! I see that you have issues with your secondary monitor. What happens if you disconnect the first monitor that is currently work and just hook up the W2072a by itself? If it works then we know it is something with your computer system and if it still fails then their could be a problem with the monitor.

FF always opens in 2nd monitor

I have dual monitors and occasionally set my 2nd monitor as the primary when testing software. On reverting back to use my 1st monitor as primary (using display settings) I find FF disregards the changed setting and always opens on the second monitor. Reboot does not resolve the problem. All other apps open in primary.
Any way to resolve this?

Maybe it was fixed in newer versions of Firefox? You are using Firefox 3.5.
If you see that Firefox 3.6 has the same problem, read [https://support.mozilla.com/en-us/kb/basic+troubleshooting this] and, if you see it's a bug with Firefox, file a bug at [https://bugzilla.mozilla.org bugzilla], if it hasn't been filed before.

Logic always opens on 2nd monitor!

Hi,
I am using Logic Studio 9.0.1 under SnowLeopard. I have the annoying problem that my Logic always opens on my 2nd monitor, even when I create a new project.
How can I change this?
Thanks in advance.
BiTRiP

Check to make sure that your 2nd monitor is not setup as the primary monitor. I have 2 monitors as well and primary is on my left and 2nd on right. Take a look in the system pref to see if thats the case. have you tried swaping the cables on the video card?
