A:Answer This is a very good question, and the short answer is: You cannot replace or “upgrade” the built‑in HDMI 1.4 port to HDMI 2.0. The HDMI port is physically wired to the motherboard and GPU. On laptops:
HDMI version (1.4 vs 2.0) is determined by:
The motherboard traces,
The display controller in the CPU,
Firmware/BIOS.
It is not a modular or swappable component.
