    many monitors, for sure pro grade
    have 2 resets in the OSD
    1: total reset..
    2: or just your custom color settings,
    the manual covers this why not read it first then ask questions.

    to Hyjacker 2021.
    monitors many , go to Peacock color spectrum mode, this is called the auto DISPLAY self test.
    if there is no input it goes to Peacock mode, the later goes to sleep if PC is dead
    the cable is bad
    the cable plugged in wrong
    or using the wrong PC video port. (inactive) of PC has PCI-3 slot video card only that works now.


    why in the word not tell what PC you have first.
    or is this NVR or DVR CCTV used monitor
    what is the monitor used for, NOT TOLD but this is a computer forum so must be PC right.
    the PCs vans must spin, if not PC is dead.

    some monitors have 3 ports on the rear, and you need to go to the monitors OSD menu and select the one you are using to PC, or the monitor fails.
    some monitors have auto port selection feature, some work others do not. use manual choice by you.

    here is a list
    connect MON to your PC, my guess VGA port, end to end. (no cable told by you so I guessed)
    turn on PC first. hear fans it is good sign PC is not dead. (CPU is a chip )
    then at monitor TURN IT ON< and press (ITS) menu key.
    see OSD memu pop up. (all monitors do this)
    then click inputs choice VGA (from DVI)
    and save
    and exit OSD.
    see it does work.

    PC are computers and not CPU, CPU is only a chip. stop calling computers CPU or get wrong answers you will
    or only ask Indians? but NO PC told at all.

    the manual is free to read still, google it see it read it , it tells you how to use this monitor.
    all manuals for MON back to year 2000 are easy to find.
    RTM
    read page in INPUT SELECTION.
    READ IT. NOW.

* Power the monitor off
* Disconnect all cabling from the bottom and/or sides of the monitor (especially the power cord)
* Press and hold the monitor power button down for 5 seconds
* Reconnect only the monitor power cord and either the #1 blue VGA or #2 white DVI (not both from one video card)
* Power the monitor on
* The PC should already be on. The monitor should auto sense the #1 blue VGA or #2 white DVI. If it does not, press the Input Select button and change to #1 VGA or #2 DVI

SOURCE: check signal message when data cable unplugged. blank screen when data cable plugged

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...

SOURCE: Acer AL1916W 19" problem

Hello mat78, Unfortunatelly the problem is hardware based. You will need to have the monitor repaired in a service center. Here's why: LCD/TFT monitors don't produce light themselves. They are composed by a matrix of transistors (TFT - thin film transistor) that have the property to reflect or allow some light (certain wavelenghts)to pass through them. They don't produce light by themselves. Instead there is a fluorescent tube (neon like) light inside the monitor and that's the light source used in order for you to see what's on the screen. A flourescent light is suposed to last pretty much, i don't think yours has a problem, you say it works for some seconds or so. Instead your problem is most probable with the inverter circuitry that powers on that light. It's a common problem among these types of monitors but in your situation i don't think it will be an expensive repair. In the case that the screen is dark (in a dark place you can't read or view anything on it) but if you apply light to it ( a flashlight or something) and you see something, then the problem is most likely to have occured with the invertor. Try to ask at a local service center for a repair, this shouldn't be an expensive procedure. Hope this helps.

SOURCE: Mag monitor doesn't display bios post

I have no experience with the DVI links because such technology is still unavailable here in Argentina. We have DVI video cards but finding a suitable DVI monitor is another (long) story.
I think that your card (that has 2 DVI ports) is initializing one port first (the primary one) and then, when windows starts, it initializes the other and outputs video from both ports.
Try connecting the monitor in the other DVI port.
If your card has a VGA output, the VGA gets initialized first.

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 compaq presario S2021a and it appears that the dvd/cd driver isn't loaded even though i have a place put them, it doesn't recognise it

Assuming it is beyond the warranty to have it fixed, you should be able to go the web site for the maker of your DVD/CD player and after selecting the model number you have, you can "download" the driver even if the device is not working.

Also, depending upon how old your system is you might just have to replace it. They are fairly cheap to buy either on-line or from an electronics store.

If you don't know the name of the device you have installed, go to www.belrac.com they have free download that will show you EVERYTHING that is in your computer by brand name. You can even print it out for your own reference.

If you want to install a new replacement unit, it really is easy. Instructions will come with the new device or even before you buy one, go to www.youtube.com and type in "how to replace a DVD/CD on a computer" and there will be a large selection of videos to give you an idea of how it is done.

Hope this helps.

My hp w2007 monitor keeps going to sleep mode when turned on with the computer on

I'VE BEEN HAVING THE SAME PROBLEM FOR MONTHS - SOMETIMES THE MONITOR WILL BE FINE FOR A FEW DAYS AND OTHERS IT WILL NOT COME BACK ON NO MATTER WHAT I DO. HOWEVER, I FINALLY FIGURED OUT THE PROBLEM AND THUS A SOLUTION AND IT ACTUALLY DIDN'T COST ME ANYTHING.

MY CPU DOES NOT HAVE A VGA OUTPUT SO I WAS GOING TO GO BUY A VGA/DVI CABLE ADAPTER BUT INSTEAD I FOUND A VGA/DVI ADAPTER IN THE BOX THAT MY COMPUTER CAME IN. I ATTACHED IT TO THE DVI CABLE THAT I ALREADY HAVE AND PLUGGED THE DVI END INTO MY CPU (SINCE IT ONLY HAS A DVI AND NO VGA OUTPUT) AND THEN THE VGA ADAPTER END INTO MY MONITOR AND WA LA... IT WORKS NOW AND HAVEN'T HAD ANY PROBLEMS WITH IT GOING TO SLEEP.

WHAT I IMAGINE IS HAPPENING IS THAT THE DVI OUTPUT ON THE MONITOR IS FAULTY - EITHER FROM THE FACTORY OR THE PINS HAVE BEEN DAMAGED SO MY CABLE WAS NOT WORKING CORRECTLY. IN TRYING TO FIGURE OUT WHAT WAS WRONG, I BOUGHT A BRAND NEW DVI CABLE AND IT STILL DIDN'T WORK SO I KNEW IT WAS NOT THE CABLE. THAT NEW CABLE WAS RETURNED TO THE STORE FOR A REFUND!

Definitely!
As long as it's the same connection (VGA or DVI) in both the monitor and the computer itself - any monitor will do the job!
If the monitor has a DVI connector but the computer has a VGA connector only, a DVI-to-VGA adapter is required.

LG w2361vg sometimes get stuck in DVI Power Saving Mode

Maybe you can update your video card driver. My wife notebook is connected at times to my DELL17" flat screen and ever so often it cuts off in the middle of something. I update the video driver and reset the monitor to factory settings and it's working like a dream.
I suggest, you use the menu buttons on the LCD and reset it ot factory settings, and possibly update your video card.

Unable to have 1280x768 full screen with DVI cable

Use the menu button on the monitor itself to adjust for the screen size in DVI mode.

 

On your SVGA adapter, go to your display properties (right click on desktop) click ADVANCED and change the refresh rate to fix the first problem mentioned.
