Second Monitor via HDMI flicking on and off ,and green flares

[Edward]

Tired X.org, Other Nvidia Drivers, swapping and changing cables, lowering refresh rates, swapping over the HDMI to other monitor (ThinkVision .... can not remeber) now the second monitor has the exact same problem and the first one via DP is perfect (not a problem of the monitor or cable of the DP port).

Need this setup for work.
