Hi, This problem has been resolved with a simple long press in the > adjustable button at the right in the OSD of monitor. I degaussed and then reset. It was present in the special tab in the monitor menu, when you press the round button at the left. I checked with changing the numbers in position contrast etc, and it worked. simply wonderful and easy but evading solution for the past few days. It is by trial and error method i found out. Once, i long press the Reset Button, it is reporting as done. when you see the adjustments, it it amazing to find that the problem is settled. Everything is placed in default settings, and my stretched problem has been solved.
Thanks shane, for his immediate diagnostics and Boggins for gem of replies to this thread
