However, if the lamp has worked perfectly for a long time, a capacitor inside the electronics will probably lose its capacity. I2S uses Direct Memory Access so every pixel is written out asynchronously. These require a certain minimum load so the electrical switch works without leakage currents. The proximity sensor is behind the pixel. This requires at least 50W to work correctly. In the test I found one panel flickering. Problem Solved! I have re-inserted the DVI-D cable on both ends as well. This voltage is generated from the power grid by a transformer. They are nearly invisible, but they change us. Very disappointing!
