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.

2nd monitor won't work correctly !!!

Fresh install of xp on msi kt600 motherboard, and trying to get my G450 dual video card to work. Every time I try to enable dual monitor the 2nd screen seens to have really bad resolution and bad refresh rates. Can't figure out what is going on ....

Thats sounds far more likely to be an issue with the AGP Card or Drivers over the MoBo TBH??
If it's a fresh install have you ensured that you put the exact same Drivers back in etc lol?? I know that's a patronising question and I hate asking it, but it's so easily done these days with so much stuff we install too lol !!
Otherwise, more info too to go on and then hope ya sorted soon !!

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter.

My Viewsonic monitor won't work with the Imac using the Mini Port to DVI adapter. I also tried the HDMI to DVI adapter ane the Mac-Mini with same result. The monitor does work on my older Macbook Pro that has the DVI connector. Is it a Software/Driver issue ?

Should be extremely simple, please carefully read Connect multiple displays to your Mac. If you still have problems then it's probably a cable issue that would be resolved by replacing the adapter cable. You should be using this adapter. If you are using a third party adapter that might be your problem!

I set up a new airport time capsule. Most devices connected fine however now my apple tv 2nd gen won't work. I turn it on and it searches for time and date but goes no further. I can't by pass it either. Any suggestions?

Does that mean you cannot move it to the TC and plug in by ethernet? What does bypass mean?
I would still move it closer to the TC.. and just trial it there. Range on some AC models for 2.4ghz is worse than old one. For some people.
Another thing to try is fixed wireless channels.. one of the very few options still available in the AC model.. lock the 2.4ghz to 11, 6, 1 .. try it in that order.

External Monitor won't work

I have a MBP 17" Late 2011 model with the Intel HD 3000 and AMD 6770M grpahics cards. I have read through many of these posts and found the exact same problem that I am having as well. I hook up a monitor through the VGA connection; Windows sees the monitor and even correctly idenifies the model; however no picture on the screen. Also, when monitor is connected is shows the startup windows screen and even the Safe boot screen; but the second it gets into the desktop the screen goes away on the 2nd monitor. I have tried many of the solutions; updating boot camp drivers, updating AMD drivers, etc. and no joy. When updating the AMD drivers, AMD's website detected that the hardware was the 6700 series and windows 64-bit; gave me the drivers to install and when installed the drivers their program ended up saying that the hardware was incompatible and not the right one. Why is this so hard and can anyone tell me what to do, also is it possible to get windows to see the Intel HD 3000 card or is that just not possible.

I have followed your advice and still no go with dual monitor through VGA. However, here is an interesting note. Using the ATI drivers from bootcamp 4.0 disk, the program detects the graphics card as a 6740 and not a 6770M. However, AMD's own website detects it as what Apple stats in their specs, a 6770M and when it give the the drivers to install that, the program won't load it saying it is the incorrect hardware/software match up, but it does the SAME decting with the boot camp drivers and goes a head and installs the drivers for the 6740. I am not sure what to do, so here's a run down again of what I have and what I need to do:
MBP 17" 2.4 GHz Intel i7, 4GB RAM 1333
Bootcamp 4.0
Windows 7 Home Premium 64-bit edition
Trying to use dual monitors through the VGA adapter, VGA adapter and cable work (works in safe mode, start up, and in OSX). Once in Windows 7 desktop, 2nd monitor goes dark and won't respond. I have gone into safe mode, uninstalled the display drivers, clean registry, reboot into safe mode, then install the bootcamp ATI graphics drivers (no go), rinse, repeat, tried using the drivers that AMD's website detects of the device (no go), rinse repeat went back to the bootcamp ATI drivers just so I can still use the main screen.Has anyone else figured out this problem.

Ipod shuffle 2nd gen won't work, light flashing green and orange

My 2nd gen ipod shuffle won't work and the light is flashing green and orange. Or green, orange, orange, orange. I've Reset, Restarted, Restored and Re-installed, so before I chuck it out I wondered if there were any other suggestions to get it working? Thanks,

Sounds like it's still under warranty (one year). Take it back for replacement.

Preview Monitor won't Work

I am using a Blackmagic card and have updated the codecs - I did a chat with Adobe and they remotely controlled my computer and still couldn't get it to work. The monitor works fine with Final Cut but won't work with Premier CC. Help.

Hmmm ... not sure where to even start, you didn't include enough details really ...
For starters ... OS/version, which CC build you're running, some things like that? Around here this is a puzzle-out space with most of participants being "peers" in being users and not Adobe staff. Some staff post here on their own time, and are a great help. But so are many of the regular joe's and joeleen's who inhabit this space.
Not thrilled that Adobe chat & help folks couldn't find the issue, but we'll see if someone around here will take on the challenge ...

G4 AGP Graphics - 2nd display won't work after upgrading from os 10.2

I have a desktop G4 AGP Graphics with two displays. When I was running os 9-10.2, the second display worked fine, but after upgrading the os (now running 10.4), the second display still works, but has turned gray and pixelated.
When I take a screen shot, the picture shows that both displays appear clear (and in color).
Am I missing something? Thanks in advance for any suggestions

so do you have 2 different video cards driving two different monitors? or is it One video card with 2 displays?
the info you listed isnt very detailed but it does tell me you got an ATI video card with 16MB VRAM.
I assume that thats the Stock AGP 2x graphics card that came the The PowerMac G4 AGP graphics model.
why is your display set to 8bit depth? a stock 2x AGP card with 16MB VRAM should be able to support 16bit or 24bit depth even at 1024 x 768 res.
the info says also Core image not support as well as Quartz Extreme no supported. Which is significant because it could be why the 2nd Monitor doesnt display properly with Tiger.
under 10.2 there were less stringent requirements for driving video.
OSX 10.4 Tiger is much more advanced OS and has higher graphics cards requirements now.
I could be wrong, but I think you may need a newer video card that supports Quartz Extreme and Core image.
hopefully someone else will run by this topic and offer some insight aside from my own.

Have compaq desk top, trying to hook up HD flat screen monitor, won't work?

Haave Compaq, desk top, trying to hook up, HD, flat screen monitor, won't work

Hello redheadjennieo,
I'm not sure Apple is going to write drivers for a Windows Operating System, so we may have to rely on the generic drivers.
What model pavilion do you have?
What operating system?
Does the monitor say anything on the screen when it's connected to the computer and you turn it? (e.g. signal out of range, no input, etc)

Dual monitors won't work independently

Using win 7 ATI Raedon 4200 card. My second monitor displays only the primary desktop back ground. Followed all setup correctly please help

Vnyga, thanks but that's not it. The geek squad said something about my monitor plug ins I told them my computer recognizes the dual setup but won't work independently. He said you can keep tweak it but he has 3 monitors an although they will learn his only remembers about 70% of the time. I'm going to try hooking it up toy TV as a monitor. I just want to use it for security cameras. I do have a DVR I could use but I normally just use that when I'm ghost hunting. I'm actually I union millwright and part time ghost hunter so I'm not to well versed in computers or the talkology but I'm learning. Anyway my laptop w win8 works just fine. But... I truly appreciate I taking the time to respond an at least offer a solution thanks so much an I apologize for running my mouth on an on. Take care V.

Monitor won't work via mini-dvi to dvi adapter

It's a brand spanking new mac mini. I attached a 5 year old lcd monitor (always used before as VGA) using the mini-dvi to dvi adapter. I am using the monitor's dvi connector. The monitor resolution is 1280x1024.
The monitor does not work when using the mini-dvi to dvi adapter. If I remove the mini-dvi adapter and use a mini displayport to dvi adapter, it works just fine. I can keep both adapters plugged in and plug the cable into one or the other. It always works instantly when attached to the minidisplay port and doesn't work if I switch to the mini-dvi port.
I've tried the display with mini-dvi adapter on my macbook too. On the laptop, it acts like there are two screens attached, but there is no action on the external display.
As a further test, I attached the mac mini to the TV via a mini-dvi to hdmi adapter. The mini-dvi port on the mini works fine, as does the port on the laptop. The monitor works fine via minidisplay, but not mini-dvi.
Naturally, I concluded that the mini-dvi adapter was faulty. A second adapter came today, and nothing has changed. Could I have received two Apple mini-dvi adapters in a row with problems? Is there something about the monitor that doesn't like the mini-dvi port? It seems like it wouldn't like the minidisplay port either, but that one is fine.

• Went to Best Buy
• Paid for a DYNEX Mini DisplayPort to HDMI Adapter ($25)
• Came home and plugged in the adapter then the HDMI to DVI cable to the monitor. (Note: Monitor is a LG Flatron L22WTG) - DID NOT WORK
• iMac knows monitor is plugged in and I can change the resolution on both monitors and mirror. (Note: Changed to every resolutions with/without mirror image.) - DID NOT WORK
• Restarted computer - DID NOT WORK
• Turned off/on LG monitor many times - DID NOT WORK
• Unplugged/plugged back in many different ways - DID NOT WORK
• Changed the HDMI to DVI cable with a better cable - DID NOT WORK
• Installed BootCamp with Windows 7 - *BOTH WORK 100%*
• Rebooted to OS X 10.6.7 (Snow Leopard) - DID NOT WORK
• Installed Windows XP - *BOTH WORKED 100%*
• Reinstalled OS X 10.6.4 (Snow Leopard) - *BOTH WORKED 100%*
• Updated OS X from 10.6.4 to 10.6.7 - DID NOT WORK
Seems to be a driver problem with the new update (10.6.7). I will not update again till drivers are fixed.

Mercury transmit issue - 2nd monitor won't play on 2nd monitor (!)

Hi there
Having an issue with mercury transmit. Am attempting to get playback on my second monitor out of after effects, however all it will do once Transmit is activated is display the feed overlaid on the same screen (i.e. my 'home' screen) rather than on the second monitor.
Have tried every setting I can find, varied preferences, monitor locations, screen sizes etc but nothing seems to work. It works absolutely fine out of Premiere so it is purely an After Effects issue. It is outputting via HDMI to a Panasonic Viera monitor and am working on a new Mac Pro 3Ghz 8-Core Xeon E5 with dual AMD FirePro D700 cards.
Any suggestions gratefully accepted!

Thanks for the screenshot, Zen.
Given all the troubleshooting you have done, and the fact that I can not reproduce the problem, I'm at a loss for an explanation. What appears to be happening is that After Effects is using incorrect coordinates for the second monitor. Whether it is receiving incorrect coordinates from Mac OS or it is incorrectly adjusting the coordinates itself, I can't tell.
That's not to say I'm out of ideas yet.
One question is what do you have plugged into the Thunderbolt ports on the Mac Pro? I assume your primary monitor is connect to one, but what else is connected and which ports are they plugged into?
There are 6 Thunderbolt ports on the Mac Pro, but they only serve 3 Thunderbolt busses, and the HDMI shares one of the busses (ports 1 & 3 are bus 1; ports 2 & 4 are bus 2; ports 5, 6, & HDMI are bus 0). It's recommended you do not have more than one display device connected to a single bus.
So, if you have more than one display device connected to a single Thunderbolt bus, or if your primary display is on bus 0, try changing the ports the displays are plugged into.
Here's a number of other ideas and questions off the top of my head:
- In the Preview panel, is the Full Screen option enabled?
- In System Preferences > Display, for that monitor, what happens if you set the Resolution to Scaled and set the resolution to 1280x720, or any other value?
- Try creating a new user account, and test After Effects under that account. Sometimes there are non-obvious preferences or settings, this is the easiest way to isolate to that.
- Try resetting the SMC and/or NVRAM (PRAM):
