Our take
Optoma's HD27HDR combines native 1920 × 1080 imaging with 4K UHD and HDR input compatibility. The input label does not change its native resolution. Optoma also states 1080p at 120 Hz and 8.4 ms in that mode, a useful distinction for a source that can output the same timing. The lens uses a 1.47–1.62:1 conventional throw with manual 1.1× zoom. The page lists 3400 lumens without an ANSI label, so the rating should not be used as an ANSI match. Inspect the 203 W lamp and actual unit.
A fixed home room needing native 1080p, measured conventional placement, and a compatible 1080p high-refresh source.
It is not a native-4K or ultra-short-throw model, and the saved page does not establish an ANSI figure or a current streaming platform.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The page distinguishes native Full HD from 4K UHD/HDR signal compatibility.
- Optoma states the 120 Hz and 8.4 ms figures specifically for 1080p mode.
- A measured throw range and manual zoom help check whether the lens fits a conventional home room.
What to weigh up
- The 3400-lumen output is not identified as ANSI, so keep that figure separate from ANSI-rated models.
- The 203 W lamp is a consumable and the present hours or picture condition are unknown.
- A 4K signal accepted at the input does not give the projector native 4K image pixels.

What the features mean for you
Separate 4K input compatibility from native resolution
Optoma identifies the HD27HDR as a native 1920 × 1080 DLP projector that accepts 4K UHD and HDR signals. This distinction matters when comparing it with native 4K models: the source may send a 4K signal, but the projected image remains Full HD. That can still fit a living room with ordinary viewing distances and Full HD sources. If your goal is to resolve very fine detail on a large screen, compare models with a documented native 4K imaging device. Also confirm the player, receiver, and HDMI path support the input format you plan to use.
Treat the gaming timing as a specific mode
Optoma states 1080p at 120 Hz and 8.4 ms in that mode. These values should not be generalized to every resolution, input timing, or processing setting. A console or PC must output a compatible 1080p/120 signal for that mode to matter. Check the intended source's capabilities and keep the projector's output and input claims distinct. The integrated 10 W speaker can cover simple use, but a gaming or movie room may need separate audio equipment. When assessing a secondhand unit, test the exact source and timing rather than relying only on a menu label.
Measure the throw before fixing the mount
Optoma lists a 1.47–1.62:1 throw range with manual 1.1× zoom. That is conventional room placement: the projector sits well back from the screen, not on a low cabinet against the wall. Measure the desired image width and lens-to-screen distance before choosing a ceiling mount. The zoom offers a small framing adjustment but cannot replace a room measurement or shift the lens center. Confirm the image geometry against Optoma's chart and account for the mount offset. If the room cannot provide the required distance, compare a genuine short-throw or ultra-short-throw model.
Do not relabel the lumen figure
The checked HD27HDR page lists 3400 lumens, but it does not identify that figure as ANSI. Keep the method unknown rather than comparing it directly with a model whose maker names ANSI lumens. Room light, screen size, picture mode, and an aging lamp all affect the image. Ask for lamp hours and see a uniform image on the specific unit in a comparable room. If brightness is a hard decision point, use an ANSI-labeled spec from each model or arrange an in-room check. The published rating is not a measurement of a renewed or used example.
Plan for a lamp and external content source
Optoma specifies a 203 W lamp and two HDMI inputs. USB-A can supply power to an HDMI dongle, but that does not mean the projector itself includes a current app platform. Use a separate player for streaming and confirm that protected video works through the whole chain. On a used unit, inspect lamp hours, focus across the image, color, fan behavior, remote, HDMI ports, USB power, and the lens zoom. An Amazon Renewed label in the historical candidate record does not say anything about a future offer or its present condition. Verify exact model and package contents before purchase.
What else to compare
Compare BenQ HT1075 for documented vertical lens shift and MHL/analog connections, or Optoma UHD30 for a separately documented native 4K UHD model.
Before you buy
Is the HD27HDR native 4K?
No. Optoma specifies native 1920 × 1080; 4K UHD/HDR describes compatible input signals.
Does it support 120 Hz?
Optoma states 1080p at 120 Hz and 8.4 ms in that mode; verify the source and signal path.
Is 3400 the ANSI-lumen rating?
The checked page does not label 3400 lumens as ANSI, so this review leaves the ANSI value unknown.
