HDMI标准并没有直接定义线材长度
Although no maximum length for an HDMI cable is specified, signal attenuation (dependent on the cable's construction quality and conducting materials) limits usable lengths in practice.With better quality construction and materials, including 24 AWG (0.205 mm²) conductors, an HDMI cable can reach lengths of up to 15 meters (49 feet).
摘自wiki
We have seen cables pass "Standard Cable" HDMI compliance testing at lengths of up to a maximum of 10 meters without the use of a repeater. It is not only the cable that factors into how long a cable can successfully carry an HDMI signal

HDMI信号延迟高低与线材长度是没有关系的,我公司会议室就是15米的HDMI线,没有任何问题
实际在售的产品中还有30米的,不过我并没有用过
