Ultra-short-throw business projector

The DELL H452A is a 3LCD projector rated at 3100 ANSI lumens with a native 1280x800 resolution. Its ultra-short-throw design allows a large image from a very short distance, making it suitable for meeting rooms and classrooms where space is limited.

Sustained brightness and colour stability

The 3LCD engine delivers consistent colour output and maintains the 3100-lumen rating under continuous operation without the colour-breakup effect seen in single-chip designs. A 3000:1 contrast ratio supports readable text and clear graphics during extended presentations.

Installation and connectivity check

Verify that your source device provides an HDMI output compatible with the projector's HD video mode of 1080i. Ensure the mounting surface can support the 13.5 lbs weight and that the ultra-short-throw distance matches your room layout.

Questions about this item

How loud and hot does the 3100-lumen 3LCD engine get during all-day use?

The unit weighs 13.5 lbs and uses a 3LCD light engine rated at 3100 ANSI lumens; typical ultra-short-throw projectors run warm and audible after several hours.

Which cables or sources must I already own to connect to the HDMI input?

You need an HDMI cable and a source that can output 1280 x 800 or 1080i signals such as a laptop, media player or game console.

Will the 1280 x 800 native resolution and 4:3-friendly scaling work with my older VGA laptop through an adapter?

The projector accepts 1080i over HDMI; a VGA-to-HDMI adapter lets legacy laptops send a compatible signal that scales to the 1280 x 800 panel.
