My desktop pc is saying display device on vga and the colour as changed to yellowish


Make sure you didn't accidently touch the button on the monitor and change from digital to vga - happens usually when moving or adjusting your monitor for viewing.
First thing to check is to make sure the monitor cable going from pc to monitor is seated properly. To test - remove cable and put back on being sure to use the screws to tighten slightly.
Second thing to check is your windows software for recent updates - sometimes the drivers that come with your OS don't work with your video card. You can often roll back the change or go to the video card site and download the latest driver.
Thirdly if this doesn't fix the problem, you may have a faulty or loose video card. If you're comfortable working inside your pc this is relatively easy to re-seat the card, basically give it an extra push into it's slot on the board to make sure it is snug - *make sure your pc is turned off and unplug the power cord* (critical)
If re-seating the video card doesn't fix the problem you probably need a new card
Older video cards and older systems present many problems which increase the possibilities exponentially. Failure can be related to power, software, hardware and drivers. It's complicated and if you are unsure, you should take your system to a professional. If the system is under warranty, please take it back to the shop rather than try to fix it yourself and destroying the warranty.

My desktop red in colour i have lg flatron w1642s


Hi Shiva003,

This problem usually arises when a line in your signal cable is cut. I suggest you get a new signal cable and the problem will be history. When this cable is cut you may have your screen appearing reddisg, yellowish or blueish - RGB combination that produce all the other colours we see.

Regards.

My monitor turns yellowish i can still work what is the problem. the monitor is a Acer V233H


The red "gun" of your CRT monitor is going bad. You will need to get a new monitor, and you should seriously consider an LCD flat screen. It will save you allot in electricity.

A CRT monitor is a very cool piece of technology inside... even though they are going obsolete with the advent of modern LCD displays.

In every CRT (Cathode Ray Tube) monitor, there is a trio of "Electron Guns"- they fire electrons at the front of the screen, hitting it with billions upon billions of electrons... the "bullets". Each gun is aimed at a set of colored targets, called "pixels"... one gun hits red ones, one for green, and one for blue. Combinations of these colors make up everything we can see.

When the red "gun" cannot fire enough electron "bullets" at the screen, the blue and green together make the picture appear yellowish.

If you want to learn more, look up "cathode ray tube" on wikipedia for starters!

A word of warning- the technology is very cool (I used to teach how CRT screens worked as part of my job teaching Missile fire control radar for the Navy), BUT:

THERE ARE VERY HIGH VOLTAGES INSIDE A CRT MONITOR THAT CAN KILL!!! DO NOT OPEN
THE CASE!!!!

Remember- the electron "guns" inside are shooting billions and billions of electrons at the front of the screen. They are being collected from the screen by a high voltage "supply". Most CRT's operate with anywhere from 15 to 45 THOUSAND VOLTS!

this simply has to do with your vga(video card drivers).

the first approach is to try reinstalling the correct drivers for the vga.
this should in most case rsolve the issue.

do let me know if you do need more help.
good luck

Hp w2007 why does the computer go pink everything that is green is now black


All the colours on the screen are created by "mixing" the 3 "primary" colours (red, blue, green).

Once the production of "green" ceases, anything that should be "100% green" becomes "100% black",
and every colour that indicates some percentage of "green" becomes a mixture of just RED and BLUE, i.e., various shades of PINK.

First, try the monitor on another computer (desktop or laptop). If the problem persists, it's time to replace the monitor. If the problem vanishes, it's the video-card in your computer that is not generating GREEN, or it is the "data" cable between your monitor and your computer that is not transmitting the GREEN request. So, you can try replacing the data-cable, or try replacing the video-card.

My dell lcd monitor is going crazy even is safe mode it scrolls on it's own, any suggestions


I doubt if this is related to the software you installed.
Check the video lead that runs from the PC to the monitor.
Sometimes the insulation becomes damaged or the wires break.
With the computer on gently wiggle the lead around at one end or the other while watching the monitor, if the colour flickers then you have found the location of the fault.
Also check the plugs are in firmly.

I cannot ajust my screen the colours are awful


Check your vga driver is working ok otherwise run the vga driver setup ajust the resolution and refresh rate your monitor will be ok

If you monitor is red/blue or yellowish then you have to replace it because colour

Go to control panel then choose system - hardware - device manager - > expand the display adapter any exclamation mark or question mark there.

That means you have to reinstall its driver .
