Something funny and unclear happened yesterday. The engineer calls, two monitors simultaneously started to loosen. Coming here, it will be very good. Connected these monitors to another comp in the neighboring cabinet, there is no strip. I pulled the monitors back, slapped. Connected monitors from another company from the neighboring office, loose. I decided to do something with the compass. Replaced the system, it will still fade. We checked the power wires, tried in different options to connect, slash. I pulled another system from the warehouse. We installed a new monitor from the box, as well as stripes. Here, the engineer gives out that he only brushes in the morning and in the evening when it is dark on the street, and when the sun shines then the norm. Here it shaded, turned off the lights in the office, the lanes disappeared. It turned out that the cabinet replaced the mercury lamps with LEDs, and just above the table of this comrade, there was a faulty lamp that flashed, somehow the flashing frequency of the lamp coincided with the frequency of the monitor and from this there were bands. I wanted to run after the shaman. and :-)
