If you mean its displaying green, it could be a range of things.
A pin on the cord, the computers graphics card, the screens inverter.. etc. Get it checked out.
A green light on your computer monitor i think means that it is on. im not sure though

RGB - Red, Green, Blue
you need to have a computer with the red green and white plug-in's and that should be it
Yes, - Change the data cable of monitor - Changing the gamma to all red will allow you to see at least some green
how is the first computer monitor
A computer monitor is hardware. It only provides for display.
Monitor is not plugged in or monitor is not plugged in to computer
I assume the questioner meant a RGB colour model TV or computer monitor? In which case, the three colours are, red, green and blue.
Try to get one more monitor just to check. If another monitor works with your computer, you have most likely problems with your video card (if you are not lucky it can be motherboard, or motherboard + video card).
Red, Green & Blue.... Hence the term 'RGB monitor'.
Your tower is your computer. If you are asking if the monitor and computer have to match the answer is no. You can use any monitor with any computer.
