HP Phoenix computer can't detect second monitor

HI,
I have used this for a while (18 months) on one monitor and wanted to extend the desktop to a second monitor - but the system fails to detect a second monitor when it is plugged in.
It has an AMD Radeon 6850 with two DVi slots - both monitors work as I can swap them over. But neither the auto detect (HP Catalyst) or the manual detectoption show up a second monitor.
I have updated the ADM driver, restarted etc etc........ not sure what else to try. Any suggestions?
thanks
Mike

Hi MikeJeffries,
I'm sorry to hear about your problem in connecting a second monitor. Here is an article, (assuming you have Windows 8), that may be of help to you: Using Two or More Monitors with One Computer (Windows 8). Let me know if this helps at all. Best of luck to you.

Can't detect second piece IDE hardware

Quote from: LauritsT on 15-September-05, 14:30:15
Thank you for your replies. I have used the same config om my last MB, so I assume the jumpersettings are ok. I have my HDDs on different cables. Each IDE cable is attatched to a HDD and a CD-burner or DVD device. One HDD is a master and one is a slave. Same goes for the CD/DVD devices.
I'll try setting them to cable select and see if that will solve the problem.
If all of the above suggestions do not pan out try using a different IDE cable. I had an identical problem to yours and after much consternation I decided that it might be the cable. Sure enough after trying several extra cables I had lying around one worked. The MSI one didn't work, other's that worked, (and still work) perfectly fine in my other systems didn't work on my MSI board. For some unknown reason that one special cable did. Lest people think it was a simple configuration problem or that the connectors were not snug or properly set up this was not the case. The IDE system on this MB is , (or at least can be) very sensitive.

Computer can't detect airport

Hi, I'm trying to install an old airport express on someone else's computer but the computer can't detect the born

The modem will connect to the first device that it sees, so this tells us that the modem has associated with, and will remember your computer.
When you connect the AirPort to the modem, the modem still looks for your computer, but cannot find it, so it refuses to issue an IP address to the AirPort since it has not associated with the AirPort.
So, you need to make the modem "forget" your computer. You do that by pushing the reset button on the modem....if present...and then powering off the modem completely for at least 30 minutes. Longer is better. Pull the power supply from the back of the modem or unplug from the wall.
Power off the AirPort Express as well
After the power down period, power up the modem and let it run for 10-15 minutes by itself.
Then, power up the AirPort Express and let it run for 5-10 minutes.
If the Apple Store configured the AirPort correctly, you will have an Internet connection now. If not, then we have to go back to square one and completely reset the AirPort and modem again.

I'm very depressed right now.
Were are you able to *Verify iPhone Driver/Service Installation*, as mentioned in the article I linked above?
Try restarting the Apple Mobile Device Service, as shown here: http://support.apple.com/kb/ts1567.
Also, what security software is running on the PC? If you haven't already, try to update, reconfigure, or uninstall it while testing. This article: http://support.apple.com/kb/TS3125 provides additional tips that will help rule out security software issues.

Zen Touch... just installed it, but my computer can't detect

I'm sure I've put it in the right place (heh, I'm not exactly a computer genius to put it lightly) but my computer can't detect it.
Please, pleeease help me... I've only just got it and really want to use it.
Thanks

Did you plug the player into the computer before installing the software that came on the CD? If so that might be the problem...

Why can't my G4 detect second monitor!?

I just hooked a 2nd monitor to the VGA port but can't get it to work. The primary monitor is hooked to the DVI and works fine.
I opened "Displays" and clicked "Detect monitor" several times. It won't find it.
What else can I do?
thanks!

That oval connector is an ADC, similar to DVI but with power and USB signals added. It can run certain Apple displays (mostly flat panels) that do not have their own power supplies.
On both of those connectors (ADC and DVI) you will see that at one end, there is a plus-shaped area, surrounded by 4 pins at the corners. Those pins are reserved for VGA signals. The adapter Apple put in the box when it shipped connects to those pins on the DVI connector, and extracts them into a 15-pin three-row VGA connector.
It is very difficult to find a VGA extractor for ADC. But for about US$35, you may be able to find a short cable that adapts ADC computer to DVI monitor (by throwing away the power and USB signals and swapping the pins around). \[Belkin makes one, but it may be out of production.] This would allow you to move your DVI monitor to the ADC port, and then you could use a VGA extractor to get a VGA output (from the DVI port) for your second monitor.

Can't detect external monitor

I'm trying to plug a second monitor into my MacBook (13" aluminium - the MB version, not the MBP). The monitor is a 19" Iiyama, model PLE1900. I'm plugging in by DVI (DVI-D), using a Mini DisplayPort converter. The video on this laptop model is a NVIDIA GeForce 9400M.
When I plug in the monitor and turn it on, it just says "No Signal", but if I perform "Detect Displays" in the preferences, the monitor is detected, and even identified correctly.
So... I'm just stumped. Why would the lappy detect the display and then the monitor say "nothing here!"?
Is the problem due to DVI-D? The monitor also has a VGA (D-Sub) input, should I get a Mini DisplayPort adapter and try that? Obviously that an expense, so I'd rather not if I can help it.
Thanks for any replies.
Ben.

Ok,
It was neither the cable nor the computer (thanks Apple). It was the monitor's EDID profile. Dell's problem.
There's two ways to fix this. 1) It is possible (I did it) to create a custom profile using SwitchResX. You'll need to hook up your computer to the monitor using a working connexion (I used DVI) and then use the "export" function in SwitchResX. It will give you a text file. In it you'll have enough data to fill SwitchResX' form to setup a custom profile. You'll then need to restart the computer, hook it with the Displayport cable and try to use this custom EDID profile. It worked for me.
For example (and hoping it will help others) here are the data you need to setup a custom profile for the Dell 2408WFP :
Descriptor #0 - Timing definition:
Mode = 1920 x 1200 @ 59,950Hz
Pixel Clock............. 154,00 MHz Non-Interlaced
Horizontal Vertical
Active.................. 1920 pixels 1200 lines
Front Porch............. 48 pixels 3 lines
Sync Width.............. 32 pixels 6 lines
Back Porch.............. 80 pixels 26 lines
Blanking................ 160 pixels 35 lines
Total................... 2080 pixels 1235 lines
Scan Rate............... 74,038 kHz 59,950 Hz
Image Size.............. 519 mm 324 mm
Border.................. 0 pixels 0 lines
Sync: Digital separate with
* Negative vertical polarity
* Positive horizontal polarity
2) Of course, you can call Dell and tell them about it. They are sending me a THIRD replacement monitor for this. Be prepared when you call them : I spoke with two representative (and among them a "senior technician") who DIDN'T know what was a Displayport. They even tried to sell me the idea that 640x480 is the native resolution for Displayport. It was hilarious. Really. I got them to look it up on Wikipedia.
Case solved. Apple 1 - Dell 0.

Cannot detect second monitor

Hi Everyone.
I am teaching on a Power Mac G5 10.5.7
Processor 2x2.66 2GB memory
I have a projector hooked up as the 2nd monitor. Sometimes when I come into teach the projector doesn't get a signal from the computer.
I've had our IT department out many times and sometimes we get it to work by switching around the two monitor cables into their slots in the back of the tower. Two weeks ago we swapped out actual monitor cards on the mother board.
But we are still having issues of the projector not getting a signal. I'd say it's 50/50. Some days it works... some days it doesn't. When the set up does work it's works great.
I've tried everything. I've tried starting the projector first then the computer and vice-versa. I've tried selecting detect displays from System Preferences.
The projector seems to be working. It's projecting an image onto our screen but it's simply the logo and there is an error saying "no signal."
Any help is greatly appreciated.

I tried plugging a second monitor with a *Mini Display Port to DVI adapter*... work 1 out of 100
Tried with a 23'' Cinema Display, With DVI Cintiq Display and 32'' LCD TV (1280x768), everytime with the same problem, the MBP screen blinks (blue) but the second monitor stay with the message "NO SIGNAL" and nothing happens, Macbook don't detect, no option to change resolution, tried plug/unplug (sometimes with the computer off), restarted (computer and monitor) several times, reseted PRAM more then once, changed from 9400 to 9600M and so on...
I'm going crazy!
Now I have two options:
1. in case of a *driver issue* (wait for Apple for an update solution)
2. in case of a *hardware issue* (use the Apple 1 yr warranty and stay a long time without my work machine, waiting repair, since it's a custom MBP)
I only have to be sure wich case is true.

Minidisplay port can't detect a monitor

I have a S230U twist. The minidisplay port used to work with my VGA adaptor to project to a second monitor and a projecter, but recently it failed to work. I think it might be a hardware issue, but would like to try troubleshoot myself first. Could anyone suggest some methods to troubleshoot? The operating system is Windows 8.1.
Thanks. I appreciate your help.

It won't let me do that. When I go to the Network window of my System Preferences, it says Location: Automatic, and it won't let me click on New Location or on Edit Locations - they are pale grey.
Also, it says Show Network Port Configurations and it gives me six: Internal Modem, Airport, Bluetooth, Built-in Ethernet, Built-in Firewire, VPN (L2TP) whatever that is, and Ethernet Adaptor (en2), and I don't know if that is the cable from my friend's router or the new stick adaptor I bought (it doesn't change, whichever I have plugged in), but all these are also pale grey and I can't click on them or on the boxes marked New Rename Delete or Duplicate.
Also the stick adaptor I bought is not showing up in my Finder window as an attached device - shouldn't it? This means I can't eject it safely when I want to. There are no instructions enclosed with it or on the manufacturer's website.
When I click on Network Status with the cable attached, it says I am currently connected to the Internet via built-in Ethernet with the IP address 192.168.0.112 so I guess built-in Ethernet must be the cable. So if the Ethernet Adaptor (en2) is the adaptor stick, maybe it isn't being recognized by my computer because it is on channel 13?

Thanks.

@wangcutopen, this thread is half a year old. I suggest you use nvidia-settings to do your setup for your nvidia card. Search the wiki for 'nvidia', or go to nvidia's linux forum. Try google after that.
If all those steps don't work, then open a new forum thread. But only after trying all those.
EDIT: re-opening, misread the dates on the post. My bad.

U430 Touch doesn't detect second monitor

I recently got a U430 but, when I connect it to my Dell S2240L monitor using an HDMI cable, the U430 doesn't detect it. I've tested the monitor and cable. The display driver that came on the machine is from Intel (version 10.18.10.3379). The supported display driver listed on the Lenovo site is also from Intel but for an earlier version (10.18.10.3277). I've read a number of threads about a second monitor not being detected. Hase anyone else seen this?
Solved!
Go to Solution.

Hi,
Welcome to Lenovo Community Forums!
I’m sorry to hear that your U430 Touch Laptop is not connecting to the External Monitor, the issue should resolve if the latest display driver is installed in the computer, below are the link to automatically scan the computer and install the relevant driver from Intel and Nvidia:
Intel display driver auto detect
NVIDIA graphics driver auto detect
Hope this helps!!!

How to know if this computer can handle a certain monitor's resolution?

I am looking to buy a new monitor, but I am at a loss as to how to know whether my computer can handle the monitor's resolution, will be compatible with it. I used to run two NEC Multisync FE991SB (CRT) monitors side by side, and one of them died. Their native resolution seems to be 1280x1024 per monitor.

Any advice on how i can learn about compatibility? And on what card i need to buy, if i do need to buy one? Thanks.

Dear Discussion Folks,
Thank you all so much for your help. I think I understand now, as a result of your comments and this reply from NVIDIA customer support:
"I understand from your mail that you would like to know if GeForce FX 5200 Ultra supports your monitor that has a recommended digital resolution of 1920 x 1200.Please be informed that as per the NVIDIA records, the maximum digital resolution supported by this graphics card is 1600 x 1200 and the maximum analog resolution supported by this graphics card is 2048 x 1536. Since you have mentioned in your e-mail that the Apple's specs page says that the maximum digital resolution supported by this graphics card is 1920 x 1200, in this case, I request you to contact Apple Support over phone and get confirmed on this. The reason why I am requesting you to contact Apple is because, we at NVIDIA, manufacture only the basic chipsets for the graphics cards and sell them to Apple Computers. The Apple Computers produce the graphics cards using the NVIDIA chipsets."
This reassured me that there's no reason to worry about the appearance of a contradiction between the Apple tech sheet and the NVIDIA tech sheet. I went ahead and ordered this monitor today: the DoubleSIght DS- 265W.
(by the way, sorry about typing 1900x1200 when I meant 1920x1200).
After it arrives in a week or two, I'll update this thread to confirm that its resolution is supported by the GeForce FX 5200 Ultra card.
Thanks again,
Mark

Can't detect second display

I adore this shiny new iMac, but oy, is the learning curve (from 10.4) steep...
The current issue has to do with setting up a second monitor, in this case an old but serviceable 15" NEC MultiSync LCD. I bought the correct adapter to attach to the venerable VGA cable on the NEC, but I'm not getting a signal to it and Displays shows only the main monitor.
My suspicion is that the NEC is just 'too old,' but I'd be happy if it actually could be used. Back in the day I was used to a LOT of real estate (20" Apple and 19" e-Machines) and it'd be nice to have that kind of space again...
Anyone have any suggestions? If I have to I can swipe my girlfriend's newer LCD display to try a different monitor, but it'd have to be returned before she wakes up.

I just tested with my Sony 3D display. The moment the HDMI cable was plugged in, "clone" mode was activated.
The HDMI port is quite deep, so make sure the HDMI cable is all the way in. The last centimeter or so is really stiff, so it may not be all the way in. The plastic shell of the HDMI connector should be flush with the case.

Computer can't detect iphone 4, only detected as camera

My friend lent me his iphone 4 until i can change my phone, so i went home and connected it to my computer but it only detected it as a still camera.
I tried reinstalling itunes and all other advice suggested by people but it still can't be detected. But when I connected it to my brother's computer itdetected it right away. Anyone knows a solution to this? i owned an iphone 3gs before but never encountered this problem. Any help would be great. Thanks

It is a camera, that is all a computer will ever detect an iPhone as.
Is the issue that iTunes does not detect the device? If so, http://support.apple.com/kb/ts1538
