Looks like a high quality Zosion Cat8 cable. Connect it to your Spectrum DVR/Cable Box and 4k OLED TV for a super bright and clear picture. I didn't get a chance to test the full 2160 resolution as it's new to me without much source material; 4k discs/true 4k streaming etc. Normal HD is very good! The cable feels well built and thick - not cheap or unreliable. 5/βββββ
