It depends on the distance and the cable insulation. From 10 m it becomes critical. As long as it is at all possible, you should avoid plug connections, because they are the weakest point. In other words, use one 10m cable instead of two times 5m + repeater. HDMI is unfortunately also a bit finicky, as it depends on the signal strength of the end devices, but if the signal arrives, Full HD and 60 fps are no problem.
