SOURCE: "No signal detected" when LCD connected with DVI-D Cable

Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

I have a new HP pavilion slimline with Vista......a 19 inch flatscreen monitor......I went nuts with it not connecting and saying no DVI input......

I tried something and so far it has worked 10 times in a row...

start out with puter and monitor off.......turn on monitor.......let it go to sleep....then turn on puter....

I have the puter that has the start button on top of it.....not too crazy about it.....

hope this works for you.........Judy in NY

SOURCE: No DVi input, then computer goes to sleep

Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:

  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

SOURCE: My Acer P205H shows up for 1-3 seconds before

Please make sure that the screen is set to receive a Digital signal, for DVI a connection. There's usually a set of buttons on the bezel to get to the setup menu on most new LCD units.
Good luck!

  • Nothing is more annoying than a monitor that refuses to turn on. Make sure your Acer monitor is plugged in to a functioning outlet. If it's plugged into a power strip, try replacing it with a new one or moving the plug to a different outlet. Ensure that both ends of the power cable are plugged in firmly and securely, and that the connection to the monitor is not loose.
Cable Issues
  • Your Acer LCD monitor will usually accept DVI and VGA inputs. If you have an older computer, a VGA cable should work fine. If it doesn't have a VGA port, you'll need to obtain an inexpensive DVI to VGA adapter at your local computer store. A DVI cable, however, is compatible with most modern computers and offers superior picture quality over VGA. Make sure you're using the cable that's compatible with your system, and that you have the proper conversion adapter, if necessary.

I have my acer p205h 20 inch monitor hooked up to my tobshiba laptop and it works great except it will not go into sleep mode when laptop goes into sleep mode the monitor goes to there is not signal check...


Unfortunately, this is a standard problem, as when your laptop goes into sleep mode, it shuts off power to the secondary monitor, without giving it the signal to go into sleep mode. You could try digging around your settings, but most likely you'll just need to turn off the monitor when you're not using it.

My Acer P205H shows up for 1-3 seconds before showing a black screen. Connected DVI Cable but is there a need to connect vga too?


Depending upon the video port/s you have on the graphics card, you need to connector one video cable, either the DVI or the 15pin DSub to the monitor.

Display coming for 2 sec and then it goes off


Does it work well with other computers?
If you are connecting to a laptop, try switching display modes (like you would do for a projector)

Sounds like a bad video card (if embeded "built in") then you need a new mother board
