"The Pico 4's visual clarity is fantastic once you dial in the IPD correctly. The manual adjustment is smooth, and finding that sweet spot makes all the difference. No more eye strain during long sessions. Highly recommend taking the time to set it up properly!""The Pico 4's visual clarity is fantastic once you dial in the IPD correctly.
