I recently received a LDF770 flat screen. after finally getting the refresh and resolution set in linix I reset my computer and after the bios screen I got a monitor out of range message and the screen went black. After a little fiddling I noticed that the monitor had reset to a really low default (65 i believe) instead of 78. The problem is I cant figure out how to change this back and how to prevent this from happening again. Any help would be appreciated.
There may wrong setting of refresh rate. Most monitors work at 60 to 70 Hz refresh rate. Above that they tunned blank screen or out 0f range message displayed. Also check the output video signal. Please confirm technical specifications from the documentatation of the monitor.

OK,Hello. The screen resolution (probably the refresh rate also) is set higher then what your new monitor is designed for. boot your computer and hold down the F8 key this should bring up the Advanced Boot Options window. you will see a list . select Enable Low Resolution......using the up and down arrows -press enter or enter key. This usually works well for windows 7 and Vista. Now If Windows starts to your desktop you can now set your resolution and refresh rate properly- set the refresh rate at 60 Hz. Window should give you a Recommended Screen resolution rate. go ahead and use it. Good Luck
You don't say which operating system you are using.
The monitor resolves images across a fixed range of resolutions and resfresh rates.
It is the resolution of the graphics card or graphics adapter that can be changed, not that of the monitor.
Right click on empty space on your desktop > properties > settings.
Left click and hold on the slider and slide to the right in stages.
Each resolution change offers you a test page to accept or reject.
When satisfied Apply > Yes > Ok.
To reset the Refresh Rate:
Properties > settings > Advanced > Refresh Rate.
Then restart your computer.
Be careful not to exceed the resolution/refresh rate range of your monitor (1280 x 1024) / 75.0 Hz because if you do, when you restart the computer, the monitor will be unable to resolve the image and you will get a blank screen and/or an Out Of Range error message.
An out of range problem might only be resolved by using a different monitor to reset the resolution back to within the range of the preferred monitor.
I see that you mentioned you screen flashes ON and OFF then finally works if not used for a while.
>Try changing the screens refresh rate, I see you have a 19" Flat Panel LCD, set the Refresh rate to 59hz if it set to 60Hz or above.
>Also try chanigin you resolution maybe a lower resolution if you have it set to the highest, or if you have it set to the lowest try setting it to at least a higher resolution possibly 1280x 780 for a 19 inch.
>Also try to see if there anre any lose cable from the LCD to the computer try reseating those cables just to make sure that everything is connected properly.
Windows is using a video mode the LCD monitor can't display. The cable doesn't matter in this case. It's an issue of the refresh rate and the resolution set in the system.
When the system boots, hit F8 just before the Windows splash screen would come up. Start the computer in safe mode with networking support. It should be able to come up in safe mode because the resolution will go to 640x480 or 800x600 by default.
Once you get to the desktop, go under the desktop properties. Hit Advanced. then go under the monitor tab. Make sure the monitor is defined. If it says generic display it will give you resolutions and refresh rates you can't use. If it isn't defined, you can install the driver under properties.
Finally, set the default resolution to something easy like 800x600 and try the refresh around 60-65hrz.
Your computer is set to a resolution supported by your dell monitor but not the flat screen tv.
The easiest way to get it working is to turn the computer off, connect the flat panel to the computer and then turn the computer on.
To change the resolution of the flat-panel or monitor, right-click on the desktop, click on properties and then select the settings tab.
play with the screen resolution and find one that works best by trying each one and clicking apply. If you select a resolution not supported by your flat panel, computer will automatically revert to the previous resolution in 15 secs.
The TV you are hooking it to is not able to show the resolution you have the computer set to. Start by setting your computer resolution to 800 x 600. If that works than try 1024 x 768. If you go too high you will get that "out of range" message. The instruction book that came with your TV has a listing of the available resolutions the TV will show.
I assume your Samsung Magic CGB5607L is CRT monitor (Not LCD). It could be the problem with "Refresh Rate" the monitor can't handle. Set the lowest resolution with lowest refresh rate. (800x600 @ 60 Hertz). in Display Properties
