ASUS PN65 vs PN50: HDMI 2.1 and 2.5GbE make it a clear generational upgrade

The PN65 is a clear step forward from the PN50, with two big upgrades: HDMI 2.1 (up from 2.0) and 2.5GbE (up from Gigabit). HDMI 2.1 can drive a single 8K display or two 4K displays at 120 Hz each — proper modern monitor support in a palm-sized chassis. The 2.5GbE port makes large file transfers go from “annoying” to “fine” for home server or NAS use. Everything else stays the same, but these connectivity upgrades matter.
