Should a gaming room prioritize short throw, Full HD, or a high-refresh mode?

The advantages and the compromises

The key details

Model covered

H5382BD

Image format

Native 1280 × 720 DLP; 16:9

Rated light output

3,300 ANSI lumens standard; 2,640 Eco

Placement

1.54–1.72:1 throw; 1.1× manual zoom and focus

ANSI ratings appear only when a model source explicitly gives ANSI lumens. Other manufacturer light-output figures remain labeled by their original basis.

Is 720p detail enough for the viewing distance?

Acer lists native 1280 × 720 resolution in a 16:9 aspect ratio. This format suits basic widescreen video but does not provide the fine detail of a 1920 × 1080 Full HD projector. The difference can matter on a large screen, with subtitles, or when game interfaces use small text. A higher-resolution input does not change the physical panel grid. Choose it when the screen size and viewing distance make native 720p adequate, and compare a Full HD alternative when fine image detail is a priority.

What does the ANSI rating establish?

Acer lists 3,300 ANSI lumens in Standard mode and 2,640 ANSI lumens in Eco mode. The labeled basis allows a more direct model-level comparison with other ANSI-rated projectors than an unqualified lumen claim. It does not guarantee that an older lamp still produces the original output. Eco mode also changes the rating and may affect perceived brightness. Ask for lamp hours, inspect the image at the intended size, and consider screen gain and room light. The rating is a manufacturer specification, not a measurement of a particular used H5382BD.

How much room does the lens need?

The product page gives a 1.54–1.72:1 throw ratio and 1.1× manual zoom and focus. That is a conventional layout that needs a measured distance from lens to screen; the small zoom range allows some framing adjustment but cannot overcome a large placement mismatch. Calculate the target image width, then compare it with the available table or ceiling position. Acer's page describes a lamp projector, not an ultra-short-throw design. Its saved specification does not establish optical lens shift, so do not rely on shift to correct a misplaced mount.

Will its connectors and audio fit the room?

Acer's opened page lists VGA and composite video and a 3 W speaker. Those connections can suit older computers or video devices, but a buyer should not assume HDMI from the product title or from a different regional package. Check the exact unit panel and source compatibility before planning a streaming stick, console, or laptop connection. The small speaker is documented as part of the model, but its adequacy depends on the room and the working condition of the particular unit. External audio may be preferable for shared viewing.

Why verify the part number before buying?

The frozen candidate record gives part MR.JNQ11.00A, while Acer's product page lists MR.JNQ11.001 for H5382BD. The shared model name supports the projector identity, but the part-code mismatch leaves region and bundle details open. Compare the chassis label and product documentation rather than assuming the historic row proves the exact accessory package. Check lamp hours, focus across the screen, color uniformity, fan, remote, power cable, and inputs on the specific unit. The model page describes original design; it cannot confirm current offer condition, stock, or seller contents.

How the alternatives change the decision

For native Full HD and a stated 96% Rec.709 coverage claim, compare BenQ HT1070A; for a 120 Hz gaming mode and 4K/HDR signal compatibility, compare Optoma HD39HDRx.

More than 96% Rec.709 coverage; no verified ANSI figure

Placement

Dual HDMI; 1.2× optical zoom and vertical keystone

ANSI ratings appear only when a model source explicitly gives ANSI lumens. Other manufacturer light-output figures remain labeled by their original basis.

Is native Full HD the right image detail?

BenQ identifies the HT1070A as a native 1920 × 1080 projector. That is a meaningful specification for widescreen films, television, and gaming, and it should be distinguished from a projector that only accepts a higher-resolution input. Native Full HD offers less pixel detail than 4K imaging but can be a sensible match for ordinary living-room screen sizes and seating distances. Compare it with the WXGA Optoma GT750 if short-throw placement matters more, or with a 4K-capable model if image detail at a very large screen is the priority.

What does BenQ's Rec.709 claim tell you?

The launch announcement states more than 96% coverage of the Rec.709 color space. That gives a buyer a specific color-standard claim for home video, but it does not guarantee how a used projector looks after years of lamp and optical aging. Picture mode, source settings, screen, room light, and calibration also shape the result. The checked announcement does not establish the HT1070A's brightness measurement method, so no ANSI value is assigned. Ask for a demonstration of the actual unit and compare color, focus, and uniformity rather than relying on a feature headline alone.

How much placement adjustment does the lens offer?

BenQ specifies 1.2× optical zoom and vertical keystone correction. Zoom gives some latitude to frame the image after measuring the lens-to-screen distance; vertical keystone is a digital correction and does not move the optical image. The reviewed sources do not establish lens shift, so a high or offset shelf may not align as easily as an installation projector with optical shift. Measure the room before mounting and confirm the manual's image-size table for the intended diagonal. Do not assume that the short throw or a digital adjustment can replace a suitable physical position.

Will the input set suit an external video source?

The HT1070A manual identifies dual HDMI inputs, which can simplify connections to a console and a second player or streaming device. It does not establish integrated streaming apps, so service access should be planned through an external source. The model uses a lamp, which makes its condition more important than the original factory rating. Check HDMI handshakes, audio routing, menu operation, fan behavior, lamp hours, and focus on the unit itself. Confirm the full HT1070A label because BenQ's W1050-family manual covers related models and not every feature should be transferred between suffixes.

Who should compare a different BenQ or Optoma?

Choose HT1070A when native 1080p, the Rec.709 claim, and dual HDMI match an external-source home setup. Optoma HD39HDRx adds a documented 120 Hz enhanced gaming mode and 4K/HDR signal compatibility, while its 4,000-lumen wording is not labeled ANSI. Optoma GT750 instead offers short-throw geometry and 3D support but uses a 1280 × 800 panel. These comparisons make the tradeoffs clearer than treating all home projectors as equivalent. Check the exact lens, screen distance, lamp, and included remote before choosing any used offer.

How the alternatives change the decision

For a documented high-refresh gaming mode, compare Optoma HD39HDRx; for short throw and 3D support with lower WXGA detail, compare Optoma GT750.

Native WXGA 1280 × 800 DLP

Rated light output

3,500 ANSI lumens

Placement

Short-throw example: about 64.5-inch diagonal at 1 m; dual HDMI and 3D support

ANSI ratings appear only when a model source explicitly gives ANSI lumens. Other manufacturer light-output figures remain labeled by their original basis.

Will short throw solve the room layout?

Optoma's brochure gives a practical example of roughly a 64.5-inch diagonal image at a 1-metre projection distance. That can help when a rear shelf or ceiling position would put a conventional projector too close to the viewer or in the way. Measure from the lens to the screen and use the brochure's image-size table for the exact diagonal you want. Short throw is not the same as ultra-short throw: the GT750 still needs clear space and careful alignment. A measurement should come before choosing a table, mount, or screen size.

Is WXGA enough for the intended image?

The GT750's native 1280 × 800 DLP grid is a widescreen computer format often described as HD Ready. It can display video and games, but the physical panel has fewer pixels than a native 1920 × 1080 Full HD model. That difference matters more as the picture grows or when small interface text and detailed maps fill the screen. Do not interpret support for a 720p or other input format as Full HD projection. Compare the expected image size, viewing distance, and game interface detail with the alternative models before deciding that its shorter throw is worth the lower native resolution.

What does its ANSI figure add?

Optoma labels the GT750 at 3,500 ANSI lumens, which gives the buyer a measurement basis that can be compared with other ANSI-rated models. This is still an original model rating rather than a measurement of an individual used example. Room light, picture mode, image size, screen, and lamp age affect the result. The brochure lists a 4,000-hour Eco-mode lamp life, but that is not a remaining-life guarantee. Ask for the lamp-hour display and see an image at the intended size before relying on the original brightness for gaming or group viewing.

How do the HDMI and 3D features affect setup?

The brochure lists two HDMI inputs and support for several 3D formats. Two direct inputs can make switching between a console and another player easier than moving cables, while 3D gives a compatible source a dedicated playback path. Optoma notes that glasses are separately available, so their presence in any current package is unverified. No integrated streaming platform is documented; use a console, laptop, or streaming device as the source. Confirm the source's signal mode, audio route, and cable reach before installing the projector at the measured short-throw position.

What should be inspected on an older GT750?

A product brochure describes the original model, not its present condition. Verify the exact GT750 label, lamp hours, startup, focus across the full image, color uniformity, cooling fan, HDMI inputs, remote, and power cable. Check that the 3D mode you need is supported by the source and that separate glasses can be obtained. The brochure's standard-mode noise figure is 27 dB, but a particular aging fan may sound different. A tagged exact-model search helps locate matching offers; it is not proof of an ASIN, included accessory, current stock, or seller condition.

How the alternatives change the decision

Model covered

HD39HDRx

Image format

Native Full HD 1920 × 1080

Rated light output

4,000 lumens; source does not label the figure ANSI

Placement

1.12–1.47:1 throw; 120 Hz enhanced gaming mode and dual HDMI

ANSI ratings appear only when a model source explicitly gives ANSI lumens. Other manufacturer light-output figures remain labeled by their original basis.

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.

How the alternatives change the decision

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.
