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.

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
MikeHi 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.

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.

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!!!
Do post us back if the issue persists

I set up a new hp PC on Friday and managed to sucessfully transefer everything from my old one which would not work to the new (reconditioned) one. Part of this was setting up UltraMon and using 2 screens again. Everyhing worked beautifully and i was able to work for the remainder of the day.
After coming back in on Monday morning, only one monitor is working and i have spend the last 2 days looking at EVERY support side possible to resolve this issue and to no avail. I have contacted ultramondirectly but that was no help whatsoever.
It has been suggested that i may need another graphics card? If this is the case, how do i get one and fix the issue.
Thank you to anyone who is willingto offer help
This question was solved.
View Solution.Since the second monitor once worked and now it does not, it can be that either one of the components failed or there is a bad connection. Verify that the connection at port 4 is secure and that the monitor is coming on by trying it on another computer. If both of those is yes, then perhaps the displayport to DVI adapter has failed.

Adding second monitor to HP Beats Special Edition 23-n010xt All-in-One with HDMI Cable
Trying to add a second monitor to all-in-one using HDMI cable. All-in-one is HP Beats Special 23-n010xt, second monitor is Samsung SyncMaster S24B300, Op Sys is Windows 8.1. Both are connected with HDMI cable, but Windows is not detecting second monitor. Have also tried a new cable, no success. Any suggestions? Thanks in advance.
Here are the specs for your HP Beats Special Edition 23-n010xt All-in-One CTO Desktop Computer. Based on the specs, this model doesn't have a video output of any kind. The HDMI port on the side is strictly an INPUT.
The HDMI input allows you to use your computer screen with a game console or video player. To connect your computer to an external display, you will need to purchase a USB-to-video adapter such as the EVGA UV Plus+ UV39 or many other adapters on the market.
If you have any further questions, please don't hesitate to ask.

Satellite 1130-Z31: Cannot get 1600x900 on second monitor
I have a Toshiba Satellite 1130-Z31 (old one, but still works well).
Now i have attached a second monitor with a native resolution of 1600x900 pixels.
I have set the resolution of the second monitor to 1600x900, this is accepted.
However, the image on the second monitor looks ugly, and the external monitors OSD says it gets 1440x900 pixel signals from the laptop.
It seems that the Toshiba sends an image with a lower resolution than set.
I have installed the latest graphics driver - no change.
Or could this be a problem with a poor quality VGA cable or so?
Any ideas?
Thanks,
TurtleHi
Unfortunately I was not able to find info which resolutions are supported for external displays but if you cannot get 1600x900 pixels that mean that this resolution is not supported by graphic card.
Which video port do you use? VGA 15 pin port maybe? -
Second monitor stays in sleep mode even though it's detected.
Hello,
So I just hooked up a second monitor through a second VGA port on my computer. For some reason that second monitor just stays in
sleep mode and never wakes up, even if I restart the computer. I've set the settings to where it should detect by
Right Click -> Screen resolution and making sure it's detected by a VGA port. I've also set up my Graphics Card to where it's compatible with 2 monitors.Hi,
Generally speaking, this problem most probably caused by Graphic driver problem, it would be better to check if the driver was upgrade to be latest, if not, upgrade it to be latest for test.
If your computer had another integrated graphic card, try to disable one of them in BIOS for test.
Please also make sure computer motherboard chipst driver and BIOS was upgrade to be latest.
If problem persists, plase try to remove first monitor to check if the second monitor could be work correctly.
If there is any progress, please feel free let me know.

Cannot Connect a second monitor to HP 500-314PC
I have a new Pavillion 500-314. It has a VGA and DVI-D connector at rear. The comuter will not see my second monitor. I have it conneced with a dedicated line DVI-D to DVI-D. When I switch the monitors , the VGA works on both. One monitor is old and so it is connected to VGA port. The other monitor has both DVI-D and VGA, but I cannot get the DVI-D to work.
Any thought? Thanks

<Serial Number Edited By Host>Well THANKS Matt_G..... I opened in safe mode and all my previously opened tabs, from when it last worked, displayed properly. I then started Aurora normally and it failed again so took your advice about disabling Add-ons and now all is working properly again. Not sure which Add-on it was because I disabled almost a of them since they really did nothing for me. I might go back tomorrow and try to find the one that did me in. Think that when you update Aurora it checks for new versions of Add-ons and that could also have gotten me.
Thanks again,

27" ACD as second monitor -- cannot adjust brightness
I've connected a 27" LED ACD to my 27" iMac as a second monitor, but the keyboard commands for adjusting brightness do not affect the cinema display. I understand a common cause for this is that the USB isn't connected, but mine is and I can verify it is working because I have an external HD connected to the USB port of the ACD, and the iMac recognizes that it is connected.
Also, if I go into Display Preferences then I do see the Brightness slider for the second monitor. This is currently the only way I can adjust the brightness of that monitor.True, Unless there's a shortcut for that, the only way to adjust the brightness of the second monitor is by using the display preferences . same here with a MBP / 27" display.

I connect my MBPr (late 2013) to a 24" Dell monitor via HDMI using a high quality audioquest hdmi cable.
When I turn off my Dell monitor, the MBPr did not detect the monitor is being turned off.
Let's say I opened a chrome browser and I move it to the external monitor. If I turn off my Dell monitor now, the chrome browser will not automatically move back to the MBPr screen.
I have the same scenario if I just power on my MBPr now and not power on the Dell monitor. I will do this if I need to do some small stuff (like typing this post) int he middle of night and I don't want to turn on my Dell monitor.
I am not sure if this is a problem or this is a normal behaviour of the MBPr. I was like this when I was on Mavericks.
PS. If I connect my Lenovo laptop to the same monitor and I turn off my monitor, the opened applications will go back to the Lenovo screen.The hardware supports DP1.2 and MST but unfortunately at present OS X Mavericks does not.
