Both the LG C4 and LG C5 support 4K resolution at a 144Hz refresh rate across all four of their HDMI 2.1 ports. The ports on both TVs offer the full bandwidth and features of HDMI 2.1, including VRR (Variable Refresh Rate), AMD FreeSync Premium, and NVIDIA G-Sync. The LG C5 is not running at 120Hz, but rather matches the 144Hz capability of the C4 model for gaming.
