"no signal" message on monitor

A friend gave me her lenovo 3000 h series desktop. I am attempting to set it up. I have hooked up all of the wires that I know of. (we took it apart and I brought it home and am now attempting to connect it). The monitor when turned on displays "no signal" and nothing else. Any thoughts?

Hey dkcowles,
The monitor, is it using a ..
1. VGA input - http://www.firebird-systems.com/graphics/tuners/cmt345_files/dual_vga_cable.jpg
or
2. DVI input - http://www.serialdigital.com/wp-content/uploads/2008/11/dvi_connector.jpg
Depending on the back of the computer, its either a DVI or a VGA type.
if your monitor is VGA and the computer is DVI.. you will need a converter. and if you are using a converter and you get that error of "no signal" .. try changing the converter.
or you could test the monitor on a different computer

No Signal message when monitor is connected to graphics card.

So, after posting this problem on various forums, I was told my power supply (300w) was too low for my Radeon HD 7570 that I tried installing. After installing a 585w power supply, the problem still happens.
Model: HP Pavilion h8-1240t
OS: Windows 7 64-Bit
Error: Monitor says "no signal" when connected into the PCI slot where the graphics card is.
Changes:This has always been happening, haven't gotten a single card to run of this stupid computer!
The DVI cable is fully plugged in from the monitor into the PCI slot and the graphics card is fully in. The fans on the graphics card spin but it isn't detected at all. It does not show up in the device manager.
Specs:
i7-2600 3.4GHz
8GB RAM
585w Orion PSU
Radeon HD 7570 (this did not come with the computer, otherwise it would be working...)
PEGATRON CORPORATION 2AD5 1.03 (I'm assuming that's the motherboard)
This question was solved.

Hello,
I think the problem is not related to any power supply issues.
I think i know what the issue is and will post a document for you to follow. Basically the issue might be related to the UEFI BIOS, to secure boot option.
Check this document: Computer Does not Start After Installing a Video Card (Windows 8)

External monitor "No Signal" message

MacBookPro mid 2010 with 250GB solid state drive. W80183G9AGZ
Two problems, they may be related
Randomly for some time the computer restarts with the message “Your computer has restarted because of a problem”
This generates a crash report which I always send to Apple.
(Unfortunately this computer does not support Apple Hardware Test nor Apple Diagnostics).
Today the computer will not send a signal to the external monitor, ( a Samsung TV).
I have carried out the following fault finding.
DVI-HDMI cable plugged and unplugged several times in different order before and after -
Restart
Shutdown and then Restart
Reset PRAM
Reset SMC
The same when using a VGA cable.
With HDMI there is a “No Signal” message, with VGA the screen just stays black.
Both HDMI and VGA previously worked flawlessly.
Checked that the GPUs are switching correctly from the integrated Intel HD graphics to the NVIDEA GForce 330M. Previously, as soon as this happened, the external monitor desktop image would appear immediately.
The presence of the external monitor is not being sensed, in “Displays” in System preferences no second display options are present.
Questions
Is the video problem definitely the NVIDEA GPU or could it be the computer crashing problem just getting worse?
Is it possible to replace the NVIDEA GPU if it is faulty?
Although the problem seems to be the same with both HDMI and VGA could it still be a problem with the HDMI cable?

No signal message - Mac Mini - Samsung P2370HD - DVI-D cable

I just received my new Mac mini and want to connect it via DVI-D cable to my existing Samsung P2370HD monitor. I have a DVI-D to mini-DisplayPort adapter connected to the Mac Mini and then a long (3-5 ft) DVI-D male to DVI-D male cable connecting the adapter to my monitor. I have checked all connections but the monitor is giving me a "No signal" message. When I unplug the cable from the adapter, the monitor gives me a "Check signal cable" message, so it seems as if the signal is not making it through the adapter to the TV.
Can anyone offer advice? I really don't want to pay for a new monitor.

My brain finally kicked in, and I was able to get the monitor to work by using the mini-DVI to DVI cable included with the Mac Mini and connecting that cable to my DVI-D (male to male) cable. I am now getting a signal to the monitor. Guess I will be returning the Dual Link DVI to Mini Displayport adapter as it was not cheap!

here everything seems to be fine. krandrtray also shows that external monitor is operative.
after rebooting computer both monitors work, but i can't change brightness on lvds.
i'm running archlinux, but the same results were on fedora, ubuntu and mint. there is no such problem on windows xp.
maybe it is not supported yet for Core Processor Integrated Graphics, but i couldn't find such information.

"No Signal" message when conneting an external LCD through VGA connection

Hi,
I have Lenovo 3000 N100 (TYPE 0768-FPG) , OS - Windows 7.
It is connected to an external LCD (SONY LCD) and everything was OK untill one day, without me changing anything, suddenly I get "No Signal" message on the LCD when in PC mode. I tried different VGA cabels and different LCD monitor, tried formatting my machine but nothing helped.
Is there anything else I can try?

Actually, the message I get on the LCD is: "No sync".
Anyone...?

No signal message on HP 2010i using HPs500O Series desktop

Hello,
The issue that I am having is with the HPs5000 Series model # s5710f desktop. and HP 2010i monitor. The monitor displays the no signal message and then goes to sleep. I have tried to access the menu on the monitor to no avail. I have plugged the monitor with its own cables into another computer and it works fine. When the desktop is plugged into another monitor it does not work. I was using the computer just the other day with no problems. The other issue, I do not know if it is related, is that sometimes I have problems with it coming out of the sleep mode and have to manually shut it down. The only suggestion that I have seen is to open the desktop and clean it with a can of air. I was wondering if this would be my solution or if it would be someting else.
Thank You
massey76

HI massey76:
I regret that you are having an issue. If the monitor works on another computer, then the monitor itself is functioning. I am sending information for both troubleshooting the monitor, and the computer. HP 2010i 20 inch Diagonal LCD Monitor support click here. Computer Does Not Start (Windows 7) click here. I am unsure of what operating system you are running, so I just selected Windows 7. If this has not resolved your issue, would you please provided me the exact model of computer you have.How Do I Find My Model Number or Product Number click here. What operating system do you have. Do you see any lights flashing or hear any beeps on start up?

Samsung DVD Player "No Signal" Message

Since we first bought our Samsung Blue-Ray Disc Player (BD-P-1400) it will play a disc for less than five minutes, and then the TV (Samsung Series 550) displays a "No Signal" message. The DVD player is still advancing the disc, but only the error message is displayed on the TV.

My brain finally kicked in, and I was able to get the monitor to work by using the mini-DVI to DVI cable included with the Mac Mini and connecting that cable to my DVI-D (male to male) cable. I am now getting a signal to the monitor. Guess I will be returning the Dual Link DVI to Mini Displayport adapter as it was not cheap!

No signal message when connecting mini to a mermaid ventura

New here so please be gentle!
I am trying to connect a recently purchased mac mini (of fleabay) through a 15inch Mermaid Ventura monitor via a VGA converter.
The monitor works perfect but I am unable to get a signal and recieve the no signal off to sleep message. I have also used a 17 inch sony LCD and again the same yet this works with my PC...
Any ideas on what I am doing wrong? I have set the mermaid to auto settings but is the mac trying to send a signal that the screen cannot handle? or has the previous user set the resolution settings higher than the screen can handle? if so... how the **** do I reset this? or work round this? with no screen?
Mac works fine, HD spins away and I the mini chimes.. just no screen...
thanks in advance.

I know when I first got my mini, I got a 19" wide Acer monitor. Hooked it up with a DVI cable, started up the mini and got the no signal message. Hooked it up to my old PC, worked fine. Hooked it back up to the mini, turned the mini on, no signal, walked away while it started up to get something to drink, came back and it was working like a champ. I think it's got something to do with the default resolution settings somewheres, but once your mini actually starts up, it should work. Also, you could try pressing "CommandOption+PR" when you power on your mini. Press it almost immediately after you hear that "Mac sound" and it should "restart" and you'll hear that "Mac sound" again. Then, just give it a few minutes so the OS can boot up and see if you've got any signal.

My PH m7160n Desktop PC the power supply make high noise no signal to the monitor

my PH Media Center m7160n desktop PC the power supply make loud noise and no signal to the monitor I already replace the power supply but still the same, Thanks
Davilea

Hello @davilea,
I understand that you are getting a loud noise from your computer and a 'No Signal' message on your HP Media Center m7160n Desktop PC's monitor. As you have already replaced the power supply I will provide you with the HP Support document: Flat Panel Monitor Displays Message about No Signal, Signal out of Range, Sleep, or Power Save, which should help you resolve the 'No Signal' message.
Please re-post if you require additional support. Thank you for posting on the HP Forums. Have a great day!
Please click the "Thumbs Up" on the bottom right of this post to say thank you if you appreciate the support I provide!

How do i run an external monitor with my macbook and change settings so that when i close the lid the signal to the monitor is not lost and i can continue using the mac with a mouse and a wireless keyboard?

No, nothing will prevent the computer from going to sleep when you close its display except third-party hacks that are designed to do exactly that. I strongly advise against using any of those, as they may interfere with successful entry into clamshell mode (and they carry other downside risks as well). Just wait until the computer is asleep (with its sleep light pulsing), then press any key on the keyboard. It sounds as though your setup is working as it's designed to do.

No signal to VGA monitor using Mac mini display to VGA adaptor and first time boot Mac mini

Just unpacked Mac mini and powered up using Mac mini to VGA display adaptor and VGA monitor. There is no signal to the monitor ( power is on).
How to see the display?

[ 13.093] (==) No Layout section. Using the first Screen section.
[ 13.093] (==) No screen section available. Using defaults.
[ 13.093] (**) |-->Screen "Default Screen Section" (0)
[ 13.093] (**) | |-->Monitor "<default monitor>"
[ 13.093] (==) No monitor specified for screen "Default Screen Section".
Using a default monitor configuration.
First step would be to create the necessary entries (easier to make a complete xorg.conf versus xorg.conf.d/##-whatever.conf).
All Desktop Environments / Window Managers rely on X. Man pages are helpful, possibly some headaches ahead as I fought a dual-monitor display this way.
I currently run a xrandr script to switch displays on my hp pavilion: https://wiki.archlinux.org/index.php/Xrandr#Scripts

No signal on VGA Monitor

I just bought one of the new minis last night. This is my first time in the Mac world so I'm expecting to get thrown some but I'm having a monitor problem right off the bat.
I am using the mini-display to VGA adapter and get no signal on the monitor. The monitor works fine with my PC. I also tried a second monitor but get the same no signal. If I use my HDTV via HDMI I get a display fine on the TV. I went to display and tried using detect displays but nothing changes. If I change resolutions it changes on the HDTV but I never get a signal on the monitor.
Any tips to try? Are the VGA adapters known to be problematic? Maybe defective?

Hi
i did what you said and tried with other resolution/refresh rate combinations, also with anoter external monitor (and vga cable) but its still the same: monitor is detected but there's no signal.
Now I will try to chek if the adapter works on other pc and monitor.
Thanks
(anyway it was the firs time i connect this mac to an external monitor)

My Mac Mini was not sending a signal to the monitor. I powered down using the power button and now it will not start. When i power up I get a strange 2 tone sound, like a warning alarm. The fan starts, and the light comes on, but no screen

I have tried with a wired USB keyboard and mouse using a single screen. Powered up with option pressed. No change.
Reset SMC no change

Run the Apple hardware test to see what it tells you. Run the extended test when prompted, which can take awhile.

My recorded signal is not sounding like the signal I am monitoring.

My recorded guitar is not sounding like the signal I am monitoring. It sounds very good when recording, but lacks energy and detail when it is played back. If I am using input/direct monitoring am I also bypassing the Analog to Digital converters? Could this explain the difference in sound quality?
Would it be the same to monitor a signal directly out of the sound card and to monitor "through" Logic?
My sound card is a Presouns Firepod.

No.

Consult the manual of that device, to see if you can learn from where in the signal chain it gets your direct monitoring from --- PRE conversion or POST conversion... My bet is that it is pre conversion.
