    I have the same problem, using LCD VA912b, almost 1 year old.
    The power cord connect to wallet cord (not to the read of mainboard)

    the power led sometimes blink, and i can not see any (the lcd is being black). the power led is flashing, on and off, on and off.....

    I have to turn off the computer, turn off monitor power cord. wait about 20 minutes, then turn on again, it will work, but if I turn off monitor then turn on, or restart the computer. the power led will blink again :(

    Can you help me?

I have similar issues. Have moved the transformer module onto my desk top so I can unplug it easily. I don't have to wait, just interrupt the power for a moment and it will reset. It has to be a hardware problem.

I have the same problem. If the computer goes into power save mode for the monitor the VA912b won't come back on. The LED blinks and it makes a repeating "bloop" noise.

I have no solution other then what was stated. Turn it off for several minutes and turn it back on. Sometimes you have to try this repeatedly before it works. (I have two VA912b monitors that I bought at the same time and both are connected to the same pc - this only happens to one of them)

    This is EXACTLY the problem I'm having. Like a car trying to start in the cold... I hear a faint "pop" at 5-7 sec intervals as it tries to come out of sleep mode. Screen remains black, light green...but flashing slowly.

How old is the monitor? Viewsonic has a 1yr warranty on this particular monitor. There is an internal hardware issue with the monitor that will need to be diagnosed by someone with proper testing equipment.

Why my Samsung SyncMaster 743n doesn't show windows 7 "Starting Windows" screen only black screen, but after this screen it's working fine?

You may want to examine the event viewer items for any startup problems, but if this does not slow the booting down, and if everything else works fine, I don't think I would worry too much about it. It may be that the video driver is loading too late to show this screen.

Soyo monitor MT-NI-DYLM1998 "out of range."

Your windows 7 screen resolution is set too high and your display doesn't support it. There are 3 possible solutions to this problem:
1. Press F8 during startup and choose "Enable row-resolution video"
2. Press F8 during startup and choose "Safe mode" and change screen resolution there, then reboot.
3. You can always use another display (if you have one) to set screen resolution to lower value.

Monitor won't work after computer starts up

You need to be sure that your unit is unplugged first before connecting PC. You will see all of your startup settings on your PC. In order to view the desktop on your monitor (does not work on Mac OS) press CTRL+F5. Anoption box will appear and by holding CTRL button and pressing F5 you will see your options change.

Distorted shrunken picture


reduce the resolution to a bit lower and the refresh rate to a nominal 60hz and things should get back to normal

my hunch is u r using a slightly high resolution and refresh rates

but before that try the buttons on the monitor to see if expanding the image sideways or top and bottom would help initially

pls rate if this was any help

No Signal when desktop wants to load

It does not hate that monitor. I believe the problem is in the settings on your video. Your monitor cannot display them. You will most likely need to start your computer in safe mode and change the display settings on your video card or, alternatively, download updated video drivers. Also, if you can't get Windows to start in normal or safe mode, one of the options you get when you press F8 on startup is to start in VGA mode. That will get you in so you can tweak your settings, which are probably set to a resolution too high for your monitor.
