Question about Keytec Sony Multiscan E500 21 in. CRT Monitor

1 Answer

Black color displayed as green

I have 21" Sony Multisan E530. The black color is displayed in different levels of green - light, dark, bright. It's especially irritating when I watch films, because the dark borders in the top and the bottom of the overlay are green instead of black.

Re: black color displayed as green

If the owner's manual covers it, I would do a factory reset on it. I would also test the PC and video card by trying another monitor to be sure. I would check the pins for ones which are bent or broken, and check the cable for pinched spots. After that, I would say the monitor has a bad signal / video board in it.

It is 7x3cm big, and its like dark green with bright green lines. I can see underneath it my screen, but only if i look deep.

if you can hooked up with other monitor just to ensure if the problem is only with in the monitor. after you replaced with other monitor then the display is clear or good picture, that was mean the only problem is the monitor. if the upper portion is black screen or the picture not so clear the cause is busted screen back light. to see the back light you will need to remove the back cover of the monitor. then the back light is a thin cold cathode flourescent tube, it was covered with a metal shield cover protection attached at the upper portion of the screen panel display.

Lock on monitor adjustments don't know how to turn off the lock so we can adjust brightness and color

Follow these instructions :
  1. Turn on your Samsung monitor (if it isn't already.)

  2. Press the "AUTO" button on your Samsung monitor. This will run the automatic configuration utility. This will look at your current computer settings and adjust your monitor to best match those. This will take a few seconds. If this has calibrated the monitor to meet your needs, you are finished with the process. If it hasn't, continue to Step 3.
  3. Press the "Menu" button on your Samsung computer monitor.
  4. Use the arrows and the "Enter" button on the monitor to highlight and select various settings categories.
  5. Use the "Brightness" menu on your Samsung monitor to adjust how bright or dark you want the image.
  6. Use the "Colors" menu to adjust how prominent certain colors are displayed on your Samsung monitor.
  7. Use the "Contrast" menu to adjust the level of black on your Samsung monitor.
  8. Select "Save and Exit" to save your changes and exit the Samsung monitor's on Screen menu.

My monitor stays white it wont show any display

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
