At the foundation, both projectors share the same headline specs: 4K output resolution and a 240Hz refresh rate, meaning neither holds an advantage in raw sharpness or motion fluency. Where they diverge meaningfully is in the finer details. The Valerion VisionMaster Max's 4 ms response time is roughly half that of the BenQ W2720i's 8.7 ms — a gap that matters most for gaming, where lower input lag translates directly to more responsive on-screen feedback. For passive movie watching, the difference is negligible, but competitive gamers will notice it.
On HDR support, the Valerion again pulls ahead: it covers the full modern stack — HDR10, HDR10+, HLG, and crucially, Dolby Vision — while the BenQ W2720i lacks Dolby Vision entirely. Since an increasing share of premium streaming content is mastered in Dolby Vision, this is a real-world content compatibility gap, not just a spec sheet distinction. The BenQ's HDR10+ and HLG support is solid but represents a narrower coverage umbrella. Additionally, the Valerion's motorized focus allows lens adjustment without physically touching the unit — a convenience the W2720i, which requires manual focus, cannot match.
The one area where the BenQ W2720i claims a decisive win is screen size: it supports projections up to 200 inches, versus the Valerion's cap of 150 inches. For buyers with large dedicated home theater rooms who want truly cinematic scale, that 50-inch ceiling difference is significant. Ultimately, the Valerion VisionMaster Max holds the broader projection quality advantage — better response time, wider HDR compatibility, and motorized focus — but the BenQ is the right call for anyone prioritizing maximum image size above all else.
