NexiGo PJ40 Pro: problems, parts and running costs
Checked: 2026-10-19
Summary
The PJ40 Pro is a 1080p 3LCD smart projector with Google TV built in, released in April 2025. The usual complaints are fan noise, a brightness ceiling that confines it to dark rooms, and input lag that one test measured too high for gaming while another measured ~10 ms. Running costs are close to zero: the LED source is rated 30,000 hours and there is no separate streamer to buy. It is a good buy at $300 or less for a dark bedroom.
Common problems and fixes
- Fan noise — RTINGS lists a very loud fan as a primary con [1]; The Hook Up measured ~44 dB, noticeable in a silent bedroom [9]. The product page has an adjustable fan speed setting [5]. Warranty terms are unknown: ProjectorCentral lists the warranty as n/a [4].
- Input lag — RTINGS measured high input lag even in low-latency mode and calls the projector inadequate for gaming at 60 Hz [1]; The Hook Up measured ~10 ms [9]. The conflict is unresolved and no fix is reported.
- Sub-par brightness — RTINGS calls the brightness sub-par with noticeable vignetting, not strong enough to fight off ambient light [1]; topsfive.com concludes it suits dark bedrooms rather than bright or daytime viewing [9]. Reddit owners of the non-Pro PJ40 measured ~450 ANSI lumens against a 700-lumen claim [13]. No fix; the workaround is a dark room.
- No optical zoom or lens shift — both are absent and focus is manual, so placement around the 1.36:1 throw needs care [1][9]. Workaround: digital keystone correction at ±25° vertical and horizontal [5].
- No battery, no handle — the projector needs wall power and stays in the room; topsfive.com lists “requires wall power” as a con [9][1].
Parts and consumables
No other replaceable parts or consumables are reported.
Yearly running cost
No consumable purchases: the LED source is rated 30,000 hours, so there is no lamp to buy, and Google TV is built in, so there is no separate streamer [4][5]. Power consumption was not confirmed [4], so an electricity figure cannot be computed from the published data. Yearly total: not enough data.
When it is a good buy
- $300 or less — an easy call for a dark bedroom: native 1080p, Google TV, 20 W of speakers, and contrast that measured at 4,400:1 [1][9]. ProjectorCentral listed a $300 street price against a $400 MSRP (2026-08-28) [4]; topsfive.com shows $279 [9].
- $301-350 — the same package is harder to justify once the fan noise and the brightness ceiling are priced in [1][9].
- Above $350 — weak value; brighter, quieter projectors compete for the money. NexiGo’s blog listed $349.99 against a $399.99 MSRP (2026-08-14) [8] and the official collections page lists $329.99 [10].
Named alternatives:
- NexiGo PJ40 Ultra — the better choice when you want the 800 ANSI lumens but do not need the Play Store; it ships licensed Netflix apps instead of Google TV [1][5].
