    I face colour setting can't control

  • sirahari Jan 14, 2008

    All of a sudden, my monitor (Samsung-Samtron 56V) features--brightness, contrast, etc.,-- are appearing on the screen by themselves. They keep flickering on and off, lock and unlock ControlLock and do not go away even with repeated pressing of the exit button on the monitor. Keeping the exit button depressed even changes the display width, and contrast.
    So I have reinstalled the Operating system (XP). But to no avail. I had a host of viruses before reinstalling the OS. The viruses are gone. Now I have AVG free anti virus running. I have also tried downloading 3-4 antivirus' from the web and run them one after the other. But this monitor problem persists.
    Need urgent help.

    When I switch on the computer The message "Controls locked" appears. I try to remove it by pressing 'menu' and 'exit' button many times. After 15-20 attmpts the message disappears. But screen width reduces. Then I have to re-adjust the screen. This happens every time in the beginning.

Have you tried holding the "MENU" button on the front panel of the unit?

For my 150MP, it must be held in for 5 seconds. (the menu actually goes away. Then you press MENU again and it comes back unlocked.)

Hold the menu button down for 15 seconds. This worked for the Dell E173 monitor I was testing. This has worked for other models of monitors as well. I found this on the Dell support site: https://support.dell.com/support/edocs/monitors/E173FP/En/controls.htm

Unable to adjust the settings for brightness and contrast .


To adjust the display settings:

1. Press the flywheel control. The main menu appears.

The current display settings appear across the top of the main menu.

2. Rotate the flywheel to highlight an option. The name of the
highlighted option appears in the center of the menu.

3. Press the flywheel control to select the highlighted option, then
rotate the flywheel to adjust it.

Some options can only be enabled or disabled. There are also some
options that contain additional menus.

4. Repeat Steps 2 and 3 until you have made all your changes.

5. Rotate the flywheel control until Exit is highlighted, then press
it to exit the OSD control system.


OSD OPTIONS:

Contrast increases or decreases display image contrast.

Brightness increases or decreases display image brightness.

Horizontal Size increases or decreases the width of the display image.

Horizontal Position moves display image to the left or right side of
the screen.

Vertical Size increases or decreases the height of the display image.

Vertical Position moves display image to the top or bottom of the
screen,

Pincushion curves the sides of the display image inward or outward.

Trapezoid increases or decreases the trapezoid distortion of the
display image.

Degauss removes magnetic discoloration from the display image.

Recall returns most options to the original factory default settings
if the monitor is currently using a preset video mode. (See the “Video
modes” section in this guide for information about the factory preset
modes.)

Advanced Option opens the Advanced Option menu. Color opens the Color
Manager menu.

Language changes the display language for the OSD control system.

User displays information about the monitor’s preset modes.

OSD Manager moves the OSD control window on the screen.

Exit closes OSD control system.

My windows XP opens at half screen


dont know what kind of monitor you have but there should be some buttons on it to adjust things like contrast, brightness, screen size etc.. try that first

if not go to--

start -> control panel -> display -> settings -> advanced -> there should be a tab for your graphics driver software in there. try changing the screen size
