Question about ViewSonic VA902b 19" Monitor

1 Answer

Monitor doesn't display color correctly. My monitor won't display pure white. A white background in photoshop appears yellowish green and nothing will fix it. I've tried to pull up the Color Adjust menu and adjust it that way, but it doesn't work. Oddly, I can adjust the green and red sliders and notice a difference, but when I adjust the blue slider nothing changes. Is there a blue bulb (like on a TV) inside my monitor that could be burnt out?

LCD screens occasionally have what are called "Stuck pixels". There is a tutorial in wikihow which might help you out here:

Try that and see if it helps. Stuck pixels are actually a slighty common problem.

SOURCE: Monitor only displays blue color, no red or green

hi there, it may be that the RGB balance has been changed. Try getting a person that knows about monitors to calibrate the colors correctly. Or, connect the computer to a different monitor. If it still displays blue, it's a problem for a expert.

SOURCE: My E771 monitor colors suddenly shifted with

Possibilities:
1. video-card gone bad;
2. video-cable gone bad;
3. video-cable not tightly-connected to CRT;
4. video-cable not tightly-connected to video-card;
5. "red" gun inside CRT gone bad.

Disconnect the video-cable from the computer, and try again to adjust the "red". If red-free, then it's time to responsibly recycle the CRT.

Reconnect & wiggle the video-cable, to see if that induces any "red" onto the CRT.

Connect the CRT to the VGA-output port on a notebook computer, to see if that video-card generates "red" as one of the primary colours.

Give the CRT a strong "whack" on the side, to see if "red" makes an appearance.

Basic "background" colors are wrong:


Kathy...have you tried connecting another monitor to the same video card and computer? It could be...

1. Video card defective
2. VGA cable from computer to monitor defective...look for bent pins in plug.

The VGA cable from the computer video output carries three distinct colors...red, green and blue. Likewise one of these colors may not arrive at the monitor correctly or at all. The results being that all colors are incorrect.

When i view pictures in windows 7 my monitor displays a yellowish background instead of white.


Color changes on the display mostly occurs because of a faulty VGA cable or a loose connection of the cable to the VGA port at the back of your PC or Monitor. But if the cable is fixed securely at the back and the problem still persists, slightly move the cable's wire segment while observing its reaction on your monitor. Does it change colors while u do so? If it does even when the cable is securely plugged in to both the PC and the monitor, then u need to change the cable.
As for the visible display area size (technically called the Resolution) right click on an icon free area on the desktop and click Properties. At the top of the form click on the Settings tab. At the bottom of this form find Screen Resolution and adjust it to it your requirements and click Apply. On the confirmation dialogue that pops up click Yes if the displayed resolution suits u otherwise click No and try another resolution size. 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.

I believe that you must reset the colors of the screen by the buttons on it or try to set colors by the software that the product came with it if any. There should be a setting to configure the 4 basic colours like red green black etc. Try to adjust green. If nothing helpes go the monitor back to test it by the store you bought it if there is warranty. Hope that helped!

I have vertical red pinstripes when the background is white. The stripes are green on a black background. Could this be a monitor problem or the graphics card?


My monitor does it too, I'm guessing yours is a LCD? It does this when the bulbs start shorting out and aging due to an aged monitor, so certain colors will appear extremely grainy.

Colors are off after auto adjust


I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

Hope this helps some people, it sure saved my ****! ;)
