Question about Samsung SyncMaster 172N 17" LCD Monitor

1 Answer

Problem with display, need help finding what the problem is

When the monitor is turned on, the display is mainly a bright white color with horizontonal lines across it, also a 1/2 inch black horizontal line seems to be floating down the monitor, like a waterfall and starts back at the top. I need to know is this a power supply issue(capacitor replacement) or is it some lighting issue. If it is the lighting issue, anyone know how to fix it and walk me through step by step. Thanks

I have the same problem with my monitor and it did not happen until windows update started installing a driver---before that my monitor was working fine. (It was on automatic update) I think it is because the new driver sets the monitor at 100hertz and the syncmaster works best at 60 hertz ( I think).

Since I am unable to see anything on the monitor I do not know how to reset this though. I do think if I could get it working at a lower refresh rate then it would work again---damn automatic updates anyway.

I took my puter back to an earlier date before it had upgraded but my monitor still has the line thing going on. Hope someone has some suggestions for this.

    Hi bratty---hope you are still around. I had put another monitor on my computer (actually a cathrode ray monitor) and I went into the display mode on the control panel. I changed the settings to 1280 x 1024 and the color quality on highest 32 bit as was suggested on the samsung site. I then went into the advanced mode and set the screen refresh rate to 60 htz and then clicked on do not display modes that this monitor cannot display.

    Once this was done I then shut down my computer and then put my samsung monitor back on. This time when I rebooted my computer the monitor is working perfectly. I have disabled automatic updates on my windows xp as I really do feel that is why my monitor wound up getting the same old screen as yours did. I really do like this monitor and I hope that this fixes the problem once and for all.

    I am also trying out the mozilla firefox browser---time for a change. Hope this is of help to someone.

HOW TO SET BRIGHTNESS OF THE SCREEN?


Hi,

Dear User...

You can adjust the brightness and contrast of your monitor to improve the readability of text and to make digital pictures appear more like they'll look when printed.

To improve the results when adjusting the brightness and contrast settings for your display, use Display Color Calibration. (Display Color Calibration helps you adjust these color settings and others.) For more information about calibrating your display color in Windows, see Calibrate your display.

The way you adjust brightness and contrast varies and depends on your specific display.

Brightness and contrast buttons on the front of the monitor. Some monitors have brightness and contrast controls on the front and use the standard symbols shown in the following image.


On-screen menu. You can change the brightness and contrast settings for some displays by using an on-screen menu, and then setting the brightness and contrast in the resulting menu. Many times, you can view the on-screen menu by pressing a button-possibly labeled Menu-on the front of the monitor.



Thanks....

Laptop display. Laptop displays don't have brightness or contrast buttons on the front.

For a majority of laptops, there isn't a control for setting the contrast.


However, you can set the brightness of many laptops by pressing and holding the Fn key, and then pressing a function key to decrease brightness ( ) or increase brightness ( ).

http://windows.microsoft.com/en-US/windows7/Calibrate-your-display#

When using Display Color Calibration on a laptop, set the display to the maximum brightness setting.


Adjusting brightness automatically using adaptive brightness

Adaptive brightness is a feature in Windows that uses a light sensor to automatically adjust the display brightness to match the lighting conditions in your computer's surroundings.


To use adaptive brightness, you must have light sensors installed and enabled on your computer.


To determine if your laptop or computer monitor supports adaptive brightness, look for the Enable adaptive brightness setting in Power Options (mentioned in the following procedure) or check the information that came with your computer.


To turn adaptive brightness on or off

Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.


Under any plan, click Change plan settings.

Click Change advanced power settings.

In the list, expand Display, and then expand Enable adaptive brightness.


To turn adaptive brightness on or off when your computer is running on battery power, click On battery, and then, in the list, click On or Off.

To turn adaptive brightness on or off when your computer is plugged into an outlet, click Plugged in, and then, in the list, click On or Off.

Click Apply. Click OK.


hope this helps

How to change the 'Contrast' and 'Brightness' on the monitor screen


Bootup your computer and display your Windows Desktop. Make sure yourmonitor stays on for at least half an hour before you begin, so that itis properly warmed up.


Seta pure black image on the monitor so you can adjust the brightness. Toget a pure black image, do the following: Choose Start, then ControlPanel, then Display. This will open the Display Properties dialog box.Click the down arrow next to the representation of the desktop color inthe Color field. Choose black from the color palette, then click OK.


Maximizethe Brightness control on your monitor, then slowly reduce it until theblack of the image perfectly matches the black at the edge of thephysical screen. This puts the brightness at the proper setting.


Open a screen with a plain white background soyou can adjust the contrast. One of the best ways to do this is to open aword-processing document without any text in it. Gradually reduce the contrastsetting of your monitor until the white area of the screen begins to lookslightly gray or off-white. Then gradually increase the contrast until thewhite area on your monitor is pure white. This will give you the proper whitebalance. Now you've got your monitor ready for peak performance.

Hope this may help you solve your problem.

My monitor stays white it wont show any display


Hi,
black-icon.gif This icon indicates the BRIGHTNESS control, more properly called BLACK LEVEL. It adds or subtracts an offset, or bias, into the red, green, and blue signals. This control should be adjusted so that black picture content displays as true black on your monitor. Misadjustment of this control is the most common problem of poor quality picture reproduction on computer monitors, video monitors, and television sets. Later in this document, I will explain how to set this control properly. The setting is somewhat dependent upon ambient light. Modern display equipment is sufficiently stable that frequent adjustment is unnecessary.


picture-icon.gif This icon indicates the CONTRAST control, preferably called PICTURE. It applies a scale factor (gain) to the red, green, and blue signals. It affects the luminance (proportional to intensity) that is reproduced for a full white input signal. Once BRIGHTNESS is set correctly, CONTRAST should be set for comfortable viewing brightness.

The gamma can be controlled through Video Card utility which can usually be accessed by going to display properties.

Depending on your video card software you may be able to right click your desktop, select properties, select settings tab and then choose advanced, towards the bottom. In there you may find a tab called Monitor and under that tab you may or may not (depending on your video card software) be able to adjust your color correction settings(gamma & brightness & contrast).

. Right click on the desktop and then select Properties

2. Click on the Settings tab and then click on the Advanced button.

3. Click on the Color Correction tab and you will see settings for Brightness, Contrast, and Gamma
