THE DIFFERENCES, MADE VISIBLE

Visual facts

How to read this comparison
  • Manufacturer facts for the exact models shown. Not a quality rating or a test result.
  • “Different” means the known values differ, not that one is better.
  • Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

Explore the full specifications

Match the screen, lens and room. Check the stated throw ratio, lens setup and connections. ANSI, ISO, LED and centre-lumen claims keep their different measurement bases; they are not an overall picture-quality score. A projected 4K claim does not by itself identify the physical imager pixel grid. Accepted input modes remain separate.

WHAT EACH CHOICE ASKS OF YOU

What it brings and what to check

BenQ TH685i

What it brings

  • The manufacturer supplies model-specific projection, placement and connection specifications. Use the stated throw ratio, actual image size and lens configuration to plan your installation.

What to check

  • Manufacturer image and brightness claims are not an independent picture-quality test. Physical imager pixels, input limits, measurement methods, bundled TV devices and regional accessories need their own stated source scope; no overall winner or current stock is established.
