Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU. It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.
here is the simple test to detect hardware malfunction. on every monitor these days whether its CRT or LCD already programmed inside self test. detach your cable data to CPU and power on your monitor. if its displayed self test on your screen mean its OK and something wrong with your CPU, could be VGA error.
if its just black display mean some is wrong with your monitor.
if you post more detail maybe we in FIXYA could help. thanks.
You should be able to adjust the settings on the monitor to prevent it from going into power save mode, or at least to delay how long it takes before it goes into power save mode. Press the menu button and look for settings that might disable or change power save mode.
Also, does your desktop/PC display show anything before the monitor goes into power save mode? If nothing comes up, its possible that you have a loose VGA connection or that your video card/motherboard are defective in some ways. Try using a different monitor.
If the other monitor works fine with your computer, try changing/lowering the screen resolution. If in XP right-click on the desktop and go to Properties, and select the tab for display settings and adjust the resolution. If in Vista/Win7, right-click the desktop and select Screen Resolution/Display Settings and adjust it there. Then check and see if your newer monitor works on it.
If the other monitor also doesn't show any display, most likely the problem is either with your video cable or your PC's video card/motherboard, not the monitor.
if the cpu unit is working while these is happenning and you just check all the setting that has to do with the display and you fine it ok, then it the monitor itself that has a problem have it check by a monitor technician
it simply means that your cpu is not giving back signal to your monitor to process, in fact, it is a cpu problem that is why there is nothing to display in your monitor.
Your cpu froze because of that usb thing. the only way to unfreeze it is to manually reset your hardware in this order.
1. RAM modules. If you can unplug your RAM (memory modules) connected in your motherboard, please do it. Just unplug the modules and then plug it back in. if you have 2 rams, then interchange them when plugging it back. this will force your mobo to refresh its resources.
2. CPU. if you can pull out your cpu chip, then do it. this will refresh your cpu setting in your mobo. (mobo = motherboard)
Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.
This is most likely not a problem with the monitor but rather a problem with the computer. do you hear the fans running in the computer? If so then the Power Supply seems to be working which would leave the most likely things are CPU or motherboard and the only way to determine which one it is would be to try the CPU on a different motherboard or try a different CPU in that motherboard.
If the fans do not run then the problem is most likely the Power Supply. The biggest problem here is that although what I have outlined is the most likely problems there are other things that could cause this and whether the fans are running or not it could still be the CPU motherboard or Power Supply. If you can I would check the voltages from the Power Supply or at least get a power supply tester to see what that shows and work from there.
I have an LG W2261V, and an old Sharp LL-T19D1-H. The PC runs both just fine, and the PSU has plenty of power. Unfortunately the LG handles power save mode very differently, where the LG would not switch on after entering this mode unless reset (unplugged, PC rebooted, etc). Extremely frustrating, as the old Sharp never had any problems exiting its own power save mode. The LG would enter this mode based on the monitor power settings (in whatever power scheme you are using) in the screensaver tab in display properties. I fixed this by selecting "Never" for "the Turn off monitor" property. I guess this is a warning to those who may wish to buy a new LG monitor, but want to use a power scheme to turn off the monitor.
