Is the Optoma Photon Life PK32 right for you?
Good for
- Console gaming at 4K/60 (rated 16 ms) or 1080p/120 (rated 8 ms)
- High-refresh PC gaming at 1080p/240 (rated 4.6 ms)
- Quick setup: autofocus (time-of-flight sensor), motorized zoom and focus, and auto keystone
- Soundbars and receivers: HDMI 2 supports eARC; stereo sound from two 5 W speakers
What to plan for
- No built-in streaming or wireless: add a streaming stick (the USB-A port supplies power)
- Low Latency mode turns off keystone and geometry correction; the 33.8 ms measured at 4K/60 applies with it off
- Auto keystone works only for images of 120 inches or smaller
- No lens shift, so the mount or table height has to be right
- Light source life is published for Eco mode only (30,000 hours)
