Expert Opinion
Professional reviewers praise the PX701‑4K for its true 4K DLP chip, impressive 3,200 lumens output, and gaming‑focused performance with 4.2 ms lag and 240 Hz refresh. The high dynamic contrast ratio and long lamp life in Eco mode are also highlighted. However, editors note that the lamp‑based light source can be noisier and less durable than laser alternatives, and the single internal speaker may fall short for immersive audio.
