Final Verdict
These serve different priorities at a similar budget-1080p tier. The TH685P is the gaming pick: a dedicated low-lag mode and 120Hz support make it the sharper choice for consoles and PC gaming, and it accepts 4K input. The HD146X counters with a meaningfully lower price and a large, well-established review record for movie nights. For any gaming, take the BenQ; for a budget home-theater workhorse, the Optoma gives up very little.
