Question about LG Computers & Internet

Open Question

I have a LG W2442 Monitor. At random, it enters DVI Power Saving Mode. It will not come out of it, and I have to do a hard reboot. I've tried changing the Power Options so it doesn't turn off automatically at a specific time. It has the latest drivers, and I've also tried altering the Manage Custom Resolutions in the Nvidia Control Panel. All to no avail. Anyone have any thoughts on the problem? I'm at the end of my rope, and prepared to throw it out the window as a P.O.S. and go get a new one from a different brand.

SOURCE: Monitor goes blank automatically after about 40 minutes...

Hi Randygui, Sounds like the back light inverter board is bad. It's a very common problem. LCD's use four small cold compact fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino

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

SOURCE: 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.

The simplest thing to do, as it is a desktop computer, is go to the control panel, power options and set everything to never so the computer never goes into standby mode.
If this does not prevent the machine going into standby mode then we need to perform further troubleshooting.
