Unplug the video cable and look atthe monitor's self test. While you are at it make sure the video cable is not loose. A cocked cable connector would do this also
This problem started around a week ago, when sometimes I noticed that the colours would go bluish for a second then go back to normal. But today it has gone bluish/green, anything red appears black.
I did not update any drivers and it is a Medion LCD 19" monitor around two years old.
tr4, I dont know what you mean by video cable, what I meant by video card was, its a NVIDIA GeForce4 MX 420 display adaptor. I know it must be one or the other, but dont know how to tell.
The video cable is the cable between the pc and monitor. Most lcd's the cable comes off. So you have 2 chances for a loose connection causing a problem
As Tr4 suggested, you can check your video cable (that connects monitor to tower) for any loose connections. If they are loose, then gently push the adapter and tighten the screws. I am sure this should solve the problem.
If that doesnt work, then do monitor self check. if it passes, then try to check the monitor with some other computer or laptop, if it works then problem is with your computer hardware might be your video card.
Please let me know one you are done with priliminary checks.
Hello, sorry for the delay in replying, I couldn't get on the forum last night as it was closed for maintenance. I have checked cables and they are fine. Yesterday display was normal on start up but within an hour it turned blue/green again. It went back to normal itself and is okay just now, after todays boot up.
I am going to uninstall and reinstall drivers plus upgrade the driver for video card. Also a friend is bringing another monitor to try for a few days to see if problem recurs. I will let you know what happens, thanks for all advice.
While you are waiting for your friend, you can unhhok the cable to the pc, either end is fine and turn on justthe monitor. You'll see a test pattern on most monitors. some need the menu selected but anyways, look for the red. Then let it sit for as long as it's been working on the computer whether 5 minute or 5 hours. See if you lose the red. If you do ,the monitor is at fault. If not, It would appear to be the card in the pc.
My friend was on holiday and only got the different monitor to try yesterday, but at the weekend I was getting the usual continuing problem with the display flickering then going blue/purple. Then on boot up I got a message saying the computer battery voltage power was too low, bought a new one and fitted it and the different monitor yesterday. Now display is fine, no problem at all. I am wondering before I attach my own monitor back, could this problem have been caused by the battery power being too low?
I will fit my monitor back in a few days and let you know the outcome.
The battery keeps the cmos settings. It would be a problem when you first turn it on. What you have is a component breaking down with either power or most likely the heat given off by the workings of the components.
I was wondering how you made out, not enough people come back to share the resolution and check the solution accepted box
Have had my friends monitor for 4 days and not a flicker or a colour loss to be seen. Everything fine so this morning I put my own monitor back and within half an hour the flickering was back, also the bluish/purple display. Can conclude now it is the monitor at fault and will have to buy a new one. Any recommendations?
I would go look at the ones in the store to compare. My favorite size is 22" widescreens right now. A friend just got an acer 2216, I think thats the model to replace a 19". It looked great. You'll need to go larger on a widescreen to keep the same heigth that you had before
Don't know where you are located but a lot of places have electronics shops that can fix the monitor. It won't be cheap but may be worth it
