Washed Out Color

The display on my monitor appears all washed out. I can't even make out the words sometimes. Previously, I was able to disconnect the power supply, hold the power button in for 30 sec or so, reconnect the power supply and turn the power on and the display was perfect again. That no longer works. I might add that this washing out only occurred after shutting the computer completely down and powering it up again. Does anyone have an idea of what might be going on here?

Do you have a touch screen?
You might try
1) different brightness settings
2) different resolutions
3) update the video driver

4) try an external monitor
Does the screen clear up if you leave it on for a couple of hours?

 

Thanks. I tried, it didn't work. No, the screen doesn't get better if left on. It's actually getting worse by the day.

 

You need to connect another monitor as suggested by DOA.

 

Thanks guys! I just ordered a new computer. It was getting really bad and I've been dealing with this problem for a while. Shame that I only had the computer for less than 3 yrs!!
