Case 1. When Screen Remains Blank

• Make sure the power cord is connected securely and completely at the monitor and at the electrical outlet.

• Some Samsung monitors have a power switch on the back in addition to the power button on the front. If there is a power switch on the back of your monitor, make sure that it is turned on, and then press the power button on the front of the monitor.

• Make sure that the signal cable between your monitor and computer is connected securely and completely to the back of your monitor and to your video card.

Note: If your signal cable is not connected correctly, your monitor will display the "Check Signal Cable" message.

• Check the video card in your computer and make sure it is fully and securely inserted.

• If you are using a DVI cable, press the source button on your monitor, and make sure that the source is set to digital.

• If you are using a DVI cable and you disconnected the DVI cable when your PC was running, or you booted your PC before you attached the DVI cable, shut down your computer, reconnect the DVI cable securely, and then reboot your computer.

If the suggestions above do not resolve your problem, run a monitor self-test to check whether your monitor is functioning properly.

 

Case 2. When Screen Remains No Image

If the power LED on your LCD monitor is blinking and you have no images on the screen, either the monitor is in Power Saving mode, or you have inadvertently set your video card to a refresh rate and/or a resolution, your monitor can't handle. Both problems are addressed below.

1) Power Saving Mode

To get your monitor out of power saving mode, press a key on the keyboard to activate the monitor, and restore the image to the screen. If there is still no image and your monitor has a source button, press the source button. Then, press any key on the keyboard again to activate the monitor, and restore the image on the screen. If this does not work, go to the section on pressing the Auto Adjust button below.

2) Pressing The Auto Adjust Button

Pressing the Auto Adjust button on your monitor will adjust your monitor to the incoming signal and may give you a picture and let you reset the refresh rate and resolution in regular mode. If you do get a picture, follow the directions immediately below to change the refresh rate and resolution.

3) Changing The Refresh Rate And/or Resolution

The optimum refresh rate for all Samsung LCD monitors is 60 Hz.

4) Standard Monitors

The optimum resolution for standard Samsung monitors varies according to monitor size. The chart below shows the optimum resolutions for standard Samsung monitors by size.

5) Wide Screen Monitors

Widescreen monitors have a W in their model number (for example, 204BW.) The native resolution of widescreen Samsung LCD monitors also varies by size. The chart below shows the native resolution for most widescreen Samsung LCD monitors by size.

If your video card or video chip set does not offer a resolution of 1440x900, 1680x1050, or 1920x1200, you may try setting your monitor to the pre-set resolution closest to 1440x900, 1680x1050, or 1920x1200. If this does not give satisfactory results, see below.

In some cases, you can download an updated video card or video chip set driver from the manufacturer of your video card or chip set which will let your card provide a resolution of 1440x900, 1680x1050, and/or 1920x1200. Alternately, you can replace your existing card with a video card that provides 1440x900, 1680x1050, and/or 1920x1200 out of the box.

6) The 305T Resolution

The 305T has a native resolution of 2560x1600.

7) P (Professional) Series Monitors

Samsung P (Professional) series monitors have an optimum resolution of 1366x768.
