How can I solve the adjusting of the monitor if I haven't the resolution size. When i start windows the monitor give me a message,it tell me that the resolution screen is donw,and the program dosen't have the size.

If your resolution is too low, you can change that by clicking on the Start button and then clicking on Control Panel. From the Control Panel window, click on Adjust screen resolution from beneath the Appearance and Personalization section. From the Resolution drop-down, select the highest resolution by moving the slider to the top. Your resolution should be just fine now.

To change your font size, go back to Control Panel, search for "window color" in the search box, and then click on Change window colors and metrics". You can adjust font sizes from here.

It is telling that it wants you to set your PC Video resolution to the monitor native resolution of 1024x768 @60Hz.

Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

hi, How do u do?? You must select the right resolution for your monitor, if you tell me the exact model name, I will tell you which resolution is best for your monitor. usually the last option in resolution list (windows resolution setting) is the prefect one, but sometime it's not correct.

This means, that your operating system is not set to the recommended resolution of your monitor. Your monitor has a "fixed" resolution where the image will look best. You can change the solution in Windows XP if you right-click on a free space of your desktop, then choose "Properties". In the new window, that comes up, select the rightmost tab. There you can use the slider to adjust your resolution. Just try some different resolutions until the message disappears.If you use Windows Vista or Windows 7 you can access the resolution window by right-clicking on your desktop and selecting "Screen Resolution".

Set the resolution lower.

It is telling you that the resolution you want is beyond its normal operating range.

just drop it to lets say 800 x 600
Then bump it up one resolution at a time until you get the message again, then drop it back one.

Running monitors above the acceptable range can drastically shorten their lifespan.

Honestly, that sounds like one of two things happened. Either the resolution of your computer video card changed or (I'm not sure with your specific TV) the TV's resolution changed.
If through the TV menus you can adjust PC resolution, I would try changing the resolutions. In the LG 47LB5DF TV, press Menu, then go to Picture, then go down to Screen. On the screen menu, you will see Resolution, Position, Size, Phase, and Reset. First try adjusting the Resolution to some of the options you see. If that doesn't work, try to reset the screen settings.
If adjusting those settings on your TV does not help, then you will have to change the resolution through the computer. Try connecting a monitor to the computer. If you get a picture through the monitor, on the desktop right click and select Properties. If using XP go to the setting tab, if using Vista/7, select Display Settings. Lower the resolution to something you think the TV will be able to handle, then connect the PC to the TV again. If you are using an HDMI connection to the TV, you may have to turn off the computer, connect the cable, then turn the computer back on with the TV on the correct input.
If the monitor doesn't show the picture or if you don't have another monitor, you can try adjusting the picture in safe mode, by pressing F8 after you press the power button, before you see the Windows loading screen. Press if multiple times if necessary. You should see a screen that gives you a few startup options. Select Safe Mode. After Windows boots up, you should still see the screen as the resolution would have been reduced. From there try changing your display settings.
Hopefully that info has helped. I noticed that you asked this question 2yrs ago, so I hope you have already figured out how to fix your problem. I simply wished to post this in case it would help you or anyone else had a similar problem. Good luck and take care.

1: Signal out of range meas the monitor can't handle the input refresh rate. lcd and Tft monitors usually supports 60 and 75Hz refresh rates.
2: The Resolution you are using to view the desktop is too high, this number is depending on the size of the lcd monitor.
a 15" lcd usually runs with: 1024x768 with 60hz
a 17" lcd usually runs with: 1280x1024 with 60hz some of them supports 75hz.
a 19" lcd usually runs with 1600x1200 or higher.

I recommend reading the user manual if you have it, or checking the information on the manufacturer's website.

3: As a solution turn on your computer and after it passes the bios screen press F8 and select VGA mode.

This will enable 640x480 (standard vga) resolution and 60Hz refresh rate, after windows boots up you can change thease nmbers , and windows automatically asks for turning to 800x600 60Hz.

If you want to change the resolution go to: Right click on your desktop, select properties , select settings tab, and adjust the resolution on the bottom of the window.

Hope this helps, good luck.

Since this was a new out of the box computer, Safe Mode was not allowed. In order to change monitor settings (resolution), I had to use another monitor, in this case a newer CRT. With the CRT, the computer booted up, no problem. Once booted, I turned down the monitor resolution and saved. Now when the Princeton LCD was plugged in and the computer restarted, everything works fine. Now the resolution could be set to limits of the monitor.

You need to get your computer in the correct resolution and refresh rate to make the monitor work. It looks like the correct numbers for your monitor are:

Resolution: 1024x768 pixels
Refresh Rate: 60 hz

You can change these settings in the display tab or display properties (In XP - right click desktop, click properties, under settings tab adjust resolution and then click advanced, the monitor tab, and make sure refresh rate is set to 60 hz)
