Re: problem with my monitor
There is no reason that a monitor only 6 months old should cause problems like this. Either Acer should fix your monitor or you have a video card problem. Bringing your monitor to a computer tech place may be a good start. They should be able to hook it up and see if it does the same thing on their computer and FOR FREE. If the problem clears up on their computer, your video card or driver is defective.

I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.
hi if its an LCD monitor then its a fault of the screen itself if its under warranty then return it. If not You could try updating video drivers but i believe this is not the problem...proberly new monitor needed im afraid
It's seems you had a stuck pixal... Turn your monitor off and try this tips: Wn't work in every case. It may take a few attempts to make sure you are pressing exactly on the dead pixel.These instructions will fix "stuck" pixels, not "dead" ones, like red, blue or green. An alternative, but similar technique involves gently massaging the stuck pixel with a warm damp soft cloth.Alternative technique to tapping: Using a rounded pencil eraser, push with moderate pressure into screen at stuck pixel.
You might be able to take back the monitor since you just bought it, but manufacturers generally have a specified number of bad pixels for which they deem the panel to be functioning acceptably and they will only replace it if the number of bad pixels exceeds that limit.
Redhat 9 is rather old and I don't remember if this will work, but just in case get to a prompt and type 'setup' as root. If it is there you will have several choices of what to set up. Choose X configuration. If your monitor is not in the list, select one of the generic LCD monitors that match the native resolution of your monitor. You could also tweak /etc/X11/xorg.conf to a resolution that will work but I doubt you want to tackle that.
your problem is in blue color cathode circuit.
as you say that it becomes ok tha5t means
1 cable wire is loose from computer to monitor.
2 crt base loose.
3 loose contact in blue video ckt.
4 signal processor cable to crt board connector loose.(blue wire)
