I have 15 computers in the office with 2 monitors each. A month ago one of the monitors on your graphics adapter went out. the green light was gone. I moved everything around to be sure that was it and it was. I ordered a new one. All was great for just under a month. Now same thing happened. I had an extra new one (anticipating that those I had were going to fade as well). So no green light on the new one. I must have an underlying issue. Can someone please help me? Thank you very much 
Thanks for getting in touch!
