Score: 84/100ViewSonic X1-4KPro
Score: 85/100Rankings
The ViewSonic X1-4KPro is a 4K LED projector with ultra-low gaming latency and strong brightness for bright rooms. Its weight and fan noise are notable trade-offs. Best suited for gamers and home-theater users who prioritize performance over portability.

The Optoma HD39HDR combines 4,000 ANSI lumens with an 8.4 ms input lag, delivering bright, low-lag visuals for gaming and cinema. It is limited by a lack of lens shift and relies on a lamp that will eventually need replacement, with only a 10 W speaker. Suited for budget-conscious gamers seeking high brightness.
