Review on Cable VCOM HDMI - HDMI (CG525D), 15 m, black by Adam uciuk ᠌

Maybe I'm setting something up wrong, but I ated the video card driver, on the Intel website it says that this video card supports 4k at 60Hz. But in the resolution of 1920x1080 at 60Hz, red flies appeared on a black background, as well as constant blinking with periodic disappearance of the picture altogether. This is a PC to TV connection. Perhaps this is due to the length of the cable - 3m. Maybe there are commentators who will say that I'm doing it wrong.
