Our take
Optoma's EH504WiFi is a Full HD DLP projector designed for fixed installations. Its datasheet lists native 1920 × 1080, 5,000 lumens without an ANSI label, 15,000:1 contrast and a 1.41–2.24:1 throw with 1.6× zoom. It includes dual HDMI with MHL, VGA in/out, composite, LAN, RS-232, USB power and two 16 W speakers. Horizontal and vertical keystone adjustment are specified. The model name includes WiFi, but the checked datasheet does not establish an integrated streaming-app platform; verify any wireless feature and source compatibility for the exact unit.
A fixed installation using Full HD sources and a measured conventional throw, where the complete wired input and control set is useful.
Avoid it if you need battery operation, a near-wall UST installation, an ANSI-confirmed 5,000-lumen rating, current built-in apps, or a maintenance-free laser light source.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Native Full HD and a 1.6× optical zoom support detailed content and flexible fixed-room placement.
- Dual HDMI, VGA input/output, composite, LAN and RS-232 accommodate many installed source and control systems.
- Two 16 W speakers and horizontal/vertical keystone cover additional room setup needs.
What to weigh up
- The datasheet lists 5,000 lumens without identifying an ANSI method.
- A 1.41:1 minimum throw remains conventional and needs measurable room distance.
- The lamp and projector size require maintenance access; the saved material does not establish streaming apps.

Full review: how the features affect your choice
What the features mean for you
Full HD fits detailed installed content
Optoma specifies native 1920 × 1080 DLP resolution for the EH504WiFi. This supports Full HD presentation and video sources without relying on an input label to imply a different native panel. The 15,000:1 contrast figure is another manufacturer specification, not a guarantee of perceived contrast in every room. Consider the screen, ambient light and source format as a system. The model's resolution is useful for detailed signage, meetings or video, while its conventional installation design means it should be selected with a specific lens position and service location in mind rather than treated as a portable projector.
Preserve the unqualified lumen wording
The EH504WiFi datasheet lists 5,000 lumens, but it does not establish an ANSI measurement method. Keep that value in its published wording and do not put it into an ANSI comparison as though the method were confirmed. This distinction matters for planners and buyers using a threshold-based procurement specification. The lamp's age and current image mode also affect a used example, so the original number is not a promise of present output. Ask for exact documentation if ANSI comparability is required, and inspect the real projector under a representative source before committing to a large venue screen.
Use the zoom range for a measured fixed location
Optoma gives the EH504WiFi a 1.41–2.24:1 throw ratio and 1.6× zoom. That provides a substantial range for a conventional projector, but the minimum is still far from an ultra-short-throw placement. Calculate lens distance from the required screen width and check ceiling height, mount offset and service clearance before installation. Horizontal and vertical keystone correction can help align the image, but an accurate physical position gives a cleaner result. The zoom lets the installer refine image size after mounting, not ignore room measurements or choose an arbitrary projector-to-screen distance.
Match the extensive inputs to the source rack
The datasheet lists two HDMI inputs with MHL, VGA input and output, composite video, LAN, RS-232, USB power and 3D sync, along with two 16 W speakers. That mixture can suit a venue or meeting room that has both current digital players and legacy sources, plus external control. The model name's WiFi label should not be mistaken for proof of onboard apps; this source packet does not document a streaming operating system. Identify the actual wireless hardware, network needs and source devices before choosing it. Confirm that each required input is present and working on the installed or used unit.
Plan maintenance and room access
Optoma lists lamp life across several modes, from about 3,000 hours in bright mode to longer ratings in eco and dynamic operation. A used lamp's remaining life depends on its own hours, settings and replacement history, so request the counter and watch a full startup. The dual 16 W speakers may cover basic room audio, while larger spaces may need a sound system. The datasheet describes a lamp-based, AC-powered installation projector, not a battery unit. Leave space for ventilation, access to the lamp door and service work, and confirm that the room can accommodate the minimum 1.41:1 throw distance.
Compare for your needs
For an ANSI brightness requirement, use a model whose official sheet names ANSI as the method. The EH504WiFi offers a broad conventional throw range and many connections, while its 5,000-lumen figure remains method-unspecified.

Before you buy
What is the EH504WiFi's native resolution?
Optoma specifies native 1920 × 1080 DLP resolution.
Is the 5,000-lumen figure ANSI?
The datasheet lists 5,000 lumens but does not identify ANSI as the measurement method.
Does WiFi in the name mean it has streaming apps?
The checked datasheet does not establish an onboard streaming platform; verify the exact wireless configuration and plan for an external source if needed.
