Optoma UHD38x
$51 under the $1,000 cap
The brightest 4K-output projector under the cap and the fastest — 10 sources back it: 4,000 ANSI lumens with 4.2 ms input lag at 1080p/240 Hz.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It runs on a lamp, and it has no apps. Budget $100-200 for a replacement bulb every 4,000-15,000 hours — about $0.02-0.04 per hour of viewing — and there is no smart platform at all, so add $30-50 for a streaming stick before you can watch anything.

Traps — this verdict avoids
Why the Optoma UHD38x is right for you
It avoids every trap below — and for anyone, no cap, it is the pick because it delivers:
The 4K that isn't
No projector under $1,000 has a native 4K imaging device. Every "True 4K UHD" model here is a 0.47-inch 1080p DLP chip using XPR four-phase pixel shifting, or 1080p 3LCD panels shifted by Epson's 4K PRO-UHD. The raster really is 3840x2160; the panel is not. Genuine native-4K home projectors start well above $5,000.
The projector is not the purchase
Nothing on this list includes a screen — a quality 100-inch screen adds $100-400. Lamp models need a $100-200 bulb every 4,000-15,000 hours. Most have no licensed Netflix app, so add $30-50 for a streaming stick, and $50-200 for a soundbar because the built-in speakers are casual-grade.
Lumens are a lab number
ANSI and ISO 21118 ratings are measured in the brightest picture mode — in an accurate mode expect 60-80% of the rated figure. A single-chip DLP's 4,000 ANSI is not the same as a 3LCD's 4,000 ISO, where color brightness equals white brightness. Any unqualified "lumens" number on a cheap projector is marketing, not measurement.
