Final Verdict

Nearly identical on paper — bright 1080p DLP around the same price. The TH575 has the edge for gaming (dedicated game mode, slightly brighter) and carries a bigger, stronger review base. The HD146X counters with slightly better contrast tuning for movie nights. For mixed use or any gaming, take the BenQ; if you find the Optoma meaningfully discounted, it gives up very little.
