What would cause very dark blurred display all modes on Samsung P2250?

I suspect the monitor is dying. Unless it is under warranty, you may need to replace it, as getting it fixed may cost more than a new one.

try the display on another computer, if the display does the same thing on another machine, then its definitely a problem in the display not in the computer drivers or bios.

Try Again By Chnaging The Old Wire With The New One

LCD Monitors having multiple inputs have option and option to select and switch between the displays from analog (VGA) or Digital (DVI) inputs. Go to the LCD menu and select input source (DVI)

Hope this helps!

hi bob you should be able to adjust the screen size via the menu on the monitor itself, (Available in Analog mode only) Note When TV signal is input in AV mode ,select “Screen Fit “to adjust vertical position in 0-6 levels. Image Size Note Supplied for the wide models only such as 16:9 or 16:10. You can change the size of the screen displayed on your monitor. PC signals • Auto - The screen is displayed in accordance with the screen aspect ratio of the input signals.• Wide - A full screen is displayed regardless of the screen aspect ratio of the input signals. Note • Signals not available in the standard mode table are not supported.• If the wide screen which is the optimal resolution for the monitor is set on your PC, this function is not performed. AV signals • 4 : 3 - Sets the picture to 4:3 normal mode. • 16 : 9- Sets the picture to 16:9 wide mode. • Screen Fit- Use the function to see the full image without any cutoff when DVI (480p/576p/720p/1080i/1080p) signals are input.

It is uncommon to have a faulty VGA input, although occasionally the pins get bent or broken on the cable. First check the cable.

Have you tried using a different source?

Some graphics cards/computers will only output DVI and VGA separatly and not at the same time. You may have to go into the display settings of your computer and change the output from DVI to VGA.

More details would be great,

Thanks!

not a big problem just change your backlight inverter

Thank you for providing your configuration details.
You have failed to specify wheather or not your LCD Display is under Warrenty.

Perhaps these simple trouble shooting procedures will get the job done.

1. use the DVI to VGA adaptor that came with your card

Plug in a regular CRT monitor to the Primary Display Output Port using the DVI to VGA adaptor
( either port can be designated as the primary by you )
I like to use the Port nearest to the motherboard as the Primary

2. plug in the your LCD monitor on Secondary Display port using your DVI cable

At this point you should be able to see your desktop on the Primary CRT Display

3. Go to the display properties and use the Nvidia Dual Display Setup Wizard

set both desktops to CLONED at a resolution of 1024x768 and set the refresh to 60Hz
which is default for most LCD displays , some have higher refresh rates , consult your user manuel

If the display resolution and refresh are set incorrectly for your CRT or LCD you will see
Signal Out of Range ( if the display has the ability to display that error message )

At this stage both displays should be showing a Windows Desktop

If you now see your desktop on both displays , you can now put the LCD on the Primary Port



No Signal Detected ( this means the display device is not receiving a signal )

If your LCD display is still displaying the error message
"No Signal Detected" after performing the trouble shooting proceedures
You may need to read the user manuel about how to enable DVI signal input.

If you are certan you have done everything correctly but still see only "No Signal Detected"

Your LCD Display may need replacement

the answer is no as VGA is a analog connection whereas the DVI connection is digital just like HDMI.
A DVI input on your display wont understand the analog signal and vise versa, hope this helps

the problem with adapters is they dont always pass all information thru,,try changing the screen resolution on the laptop down a little
