[Notes] • For supported projectors, visit https://support.epson.net/projector_appinfo/iprojection/en/. You can also check "Supported Projectors" in the app's support menu. • While mirroring your device’s screen, video and audio may be delayed depending on the device and network specifications.

Use the mirroring feature to play them. • We recommend testing the projection in advance when using this app for presentations.

Verdict

The call

The clearest difference is rating: Epson iProjection at 4.3 against 3Display's 2.3. Epson iProjection also leads on ratings volume (3.4K vs 3) and review sentiment (20% vs 0%). 3Display's advantage is update cadence (every 4 weeks vs every 6 months). On price, ads, in-app purchases and monetization model there is nothing between them.
