Our take
Optoma's HD39HDRx combines a native Full HD panel, 4K UHD and HDR signal compatibility, a 120 Hz enhanced gaming mode, and a 1.3× manual zoom. The manufacturer lists up to 8.4 ms response in that gaming mode and two HDMI inputs. It is a conventional-throw lamp projector rather than a native 4K device, and the 4,000-lumen figure is not labeled ANSI in the checked brochure. Its strongest shortlist reason is a source-documented gaming mode; the lamp, image, and actual offer package still need checking.
A conventional-throw gaming room that values a documented high-refresh mode and can use an external source.
It is not for native 4K pixels, built-in streaming apps, UST placement, or a buyer who requires an ANSI-labeled brightness figure; built-in battery operation is not documented.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Optoma documents a 120 Hz enhanced mode with up to 8.4 ms response for gaming.
- Native 1920 × 1080 and 4K/HDR input compatibility cover common home video sources.
- The 1.3× zoom, 1.12–1.47:1 throw, and two HDMI inputs help plan a fixed room.
What to weigh up
- 4K/HDR compatibility does not change the native Full HD imaging resolution.
- The 4,000-lumen claim is not labeled ANSI in the reviewed manufacturer source.
- Lamp hours, remaining lamp life, and current unit performance are unknown.

What the features mean for you
What does the gaming mode actually promise?
Optoma lists a 120 Hz enhanced mode and a response figure of up to 8.4 milliseconds. Those specifications distinguish the HD39HDRx from a projector described only for general home cinema, but they are manufacturer mode claims rather than an independent measurement of a particular setup. Verify that the console or PC can provide the intended 1080p refresh mode and check the manual's supported input timings. Picture settings, source timing, and connection behavior matter. The dedicated mode can be useful for gaming, while the model's Full HD grid remains the basis for image detail.
Is it a native 4K projector?
No. The brochure identifies native Full HD 1920 × 1080 while also listing 4K UHD and HDR signal compatibility. A projector can accept a high-resolution signal without reproducing 3840 native horizontal pixels. That distinction matters if pixel-level 4K detail is the reason for the purchase. For common gaming and video sources, Full HD may fit a normal viewing distance, but a buyer should not treat the compatibility label as native 4K output. Compare the panel resolution with screen size and seating distance before choosing it over a true 4K imaging device.
How should the 4,000-lumen claim be treated?
Optoma's brochure lists 4,000 lumens but does not label that figure ANSI. Keep it in the source's own wording and leave the ANSI profile field unknown. That avoids comparing it as though it used the same method as Acer H5382BD's 3,300 ANSI or Optoma GT750's 3,500 ANSI ratings. A lamp's age, picture mode, image size, and room light also affect what a buyer sees. Ask for lamp hours and inspect the projected image at the intended size; no current unit measurement is claimed here.
Will the lens fit a console or shelf position?
The brochure gives a 1.12–1.47:1 throw range and 1.3× manual zoom, plus vertical keystone adjustment. Measure the lens-to-screen distance and desired image width before choosing a table or mount. Zoom offers a finite framing range, while keystone is digital geometry correction rather than optical lens shift. The model is not documented as ultra-short throw, so a close-wall requirement should point to another projector. Check the exact manual for image size and offset, then confirm that the power and HDMI cables can reach without crossing a walkway.
What should be checked before relying on it?
The source lists two HDMI inputs and a built-in 10 W speaker, but it does not establish integrated streaming apps. Use an external console, player, or streaming device and verify the audio path that fits the room. The lamp and optical condition are specific to an individual used unit. Ask for its hour counter, startup, focus at center and corners, image uniformity, fan behavior, remote, and power cable. Confirm the HD39HDRx suffix on the chassis and test the desired high-refresh mode. A tagged search link is not a verified direct ASIN offer or guarantee of accessories.
What else to compare
For a documented Rec.709 coverage claim and native Full HD, compare BenQ HT1070A; for a short-throw WXGA projector with 3D, compare Optoma GT750.
Before you buy
Does HD39HDRx project native 4K?
No. Optoma identifies native Full HD 1920 × 1080; the brochure's 4K language concerns signal compatibility.
What is the gaming refresh specification?
Optoma lists a 120 Hz enhanced gaming mode with up to 8.4 ms response in its brochure.
Are its 4,000 lumens ANSI?
The checked Optoma brochure states 4,000 lumens without labeling the figure ANSI.
