Our take
The Dell 4320 is a bright, wide-format presentation projector whose defining points are its 1280 × 800 DLP image, 4300-ANSI maximum rating, and 1.28:1 minimum throw ratio. It can suit a fixed meeting room with a shorter mounting distance than a basic 1.5:1 lens, but buyers must distinguish it from the related 4220 and check the particular unit's lamp and connections.
A measured business or teaching room that needs WXGA slides, strong rated output, and more throw flexibility than a 1.5:1 lens.
It is not native Full HD or 4K, a true ultra-short-throw design, a battery projector, or a documented app-streaming system; choose a different format when movie detail or wall-adjacent placement is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Dell's guide assigns the 4320 a native WXGA 1280 × 800 DMD and an explicitly ANSI-labeled maximum of 4300 lumens.
- The 1.28–1.536:1 throw ratio and 1.2× manual zoom help installers plan a closer conventional mounting position.
- HDMI, VGA, composite, S-Video, USB viewer, and USB display functions cover several presentation-source workflows.
What to weigh up
- The shared 4220/4320 guide includes different values for the two models, so the 4320-specific line must be used.
- It is not UST; a 1.28:1 minimum ratio still needs measured space between the lens and screen.
- A maximum model brightness rating and old lamp design do not establish the remaining brightness, lamp hours, or condition of a particular used unit.

What the features mean for you
Does WXGA match your presentation material?
Dell specifies a 0.65-inch WXGA DMD with 1280 × 800 pixels for the 4320. The 16:10 shape gives a wider workspace than XGA 4:3, which can suit modern laptop slides and side-by-side content. It is still below Full HD, so dense spreadsheets, fine text, and detailed video have less native detail than on a 1920 × 1080 model. The guide also lists a separate XGA 4220; use the row that names 4320 rather than carrying over its 1024 × 768 resolution or 4100-lumen rating. Check the exact model plate before planning an installation or comparing a used offer.
What does the 4300-ANSI rating tell you?
Dell lists up to 4300 ANSI lumens for the 4320, along with a typical 2000:1 full-on/full-off contrast ratio. The ANSI label gives this model a clearer output basis than projectors whose sources state only unspecified lumens. The maximum is nevertheless a model specification, not a measurement of the lamp now installed. Image mode, screen size, ambient light, and lamp wear affect the result in a particular room. If the projector will serve a bright meeting space, inspect the image in the intended setting and request the lamp-hour reading. Do not assume that a second-hand example still produces its new-unit maximum.
How much room does its lens need?
The guide gives a 1.28–1.536:1 throw ratio for the 4320 and a 1.2× manual zoom lens. This shorter conventional range can help when a room cannot place the projector as far back as a standard 1.5:1 model, but it is not ultra-short-throw placement. Measure screen width and the distance from the lens to the screen, then confirm the target image in Dell's installation chart. Manual zoom can adjust size within the available range; it cannot move the projector to the wall or replace a mount-height check. Keep the optical center, ventilation space, power connection, and cable route in the plan before drilling or buying a mount.
Will it work with your source equipment?
Dell documents an HDMI 1.3 HDCP input, VGA inputs, composite and S-Video, analog audio jacks, a USB-A photo and Presentation-to-Go viewer, and USB display support. These can help a legacy meeting room keep older computers and local slideshow files in service. The USB viewer is a presentation function rather than a streaming-app platform, and a document viewer may not preserve every animation or font in a complex deck. Confirm the exact input labels, cable lengths, signal timings, and audio route on the projector you are considering. The manual's LAN and wireless controls do not establish built-in movie apps; a current streaming source still needs its own connection path.
Who should keep the Dell 4320 on a shortlist?
The 4320 makes most sense for an installed office or classroom with a measured screen distance, WXGA material, and sources that can use its digital or analog connections. The wide panel and short conventional throw separate it from XGA presentation models, while its higher brightness rating makes the stated output easier to compare. It remains an older projector, so confirm lamp history, fan noise, remote, ports, and any optional network accessories with the seller. Compare the Optoma EH460ST when a true 0.5:1 short-throw lens is essential; compare a native Full HD projector when video detail matters more than the 4320's presentation connections and room geometry.
What else to compare
Compare the Optoma EH460ST when the room requires a 0.5:1 short-throw lens, or a Full HD projector when presentation output is less important than video detail.
Before you buy
Is the Dell 4320 native 1920 × 1080?
No. Dell specifies native WXGA 1280 × 800 for the 4320; the shared guide also describes a different 4220 model.
Does the 4300-lumen figure use ANSI?
Yes. Dell labels the 4320 maximum as 4300 ANSI lumens in its model guide.
Is the 4320 ultra-short-throw?
No. Dell lists a conventional 1.28–1.536:1 throw ratio and a 1.2× manual zoom lens.
Can its USB port replace a streaming device?
No. Dell documents USB photo and presentation viewing, not an integrated streaming-app platform.

The decision
Choose the Dell 4320 for a measured meeting room where its WXGA panel, 4300-ANSI maximum, shorter conventional throw, and source ports match the installation.
