Monitor Trouble

[niggles]

Hi All, Just wondering if anyone has ever had a trouble with a monitor that comes on for about 1/2 a second and then the video shuts off. The Monitor is a Samsung SyncMaster 225BW 22-Inch LCD. I think the problem started with me moving plugging the monitor into my desktop after unplugging my pc from my HD TV which is displaying at 1920 x 1080 and my monitor only shows at 1680 x 1050. I have tried everything I can think of on the monitor but I think it's stuck trying to display at 1920 x 1050. Does anyone know of any tricks to reset the samsung monitor to factor default? ...is this thing toast?

have you tried connecting again to HD Tv and setting resulution on it to 1680x1050?

Your monitor (tries to) displays the resolution that the graphics card tells it to display. If your graphics card is sending and out of range signal, it will just refuse until the display options have changed. Try rebooting the PC with the monitor attached, it should redetect the resolutions the display is capable of.

Thanks very much for the suggestions so far.
I did try rebooting with it connected and disconnected. I tried rebooting with it off an on when connected. all with no results. Sorry, I left out that the monitor responds this way regardless what PC is plugged in or whether it's a DVI or SVGA cable connecting it. It does work at what ever resolution I set it to for about 1/2 a second. Anyone have anythoughts??

I would plug the monitor into the VGA port of a notebook computer and try running the LCD off that to verify that the LCD isnt getting an out of spec or out of range signal (eg, which can also include the vertical refresh).

You could also try starting the PC holding down the proper key (DEL or F2) to see if you can enter the BIOS screen which is usually at a low resolution and refresh rate that the monitor should easily display. If that turns out to work, then try to enter safe mode with the PC connected to the LCD.

I suppose that it is possible to damage an LCD by connecting it to a video signal with an excessive vertical rate. (I know that Ive seen warnings in user manuals about this.)

In my experience usually if you set the card to a refresh rate beyond it's capabilities, the monitor will either bring up the "OUT OF RANGE " screen or will go into standby mode immediately.

Yes, I did try and run the monitor off a laptop on Analog, no it's not getting an out of spec notifyication, it doesn't even come up with the menu options that the monitor would normally advise on brightness, it simply goes black after about 1/2 a second, which is I believe the 'standby mode your're talking about.

So it doesn't work with the notebook either? Sounds like the screen is hosed in that case.
