The BenQ EW800ST is a DLP short-throw projector with WXGA resolution (1280 x 800) and smart features. It’s mainly designed for classrooms but works well in other similar spaces too. BenQ calls it an interactive projector, but it’s different from their other interactive models. Those usually support interactive pens or gesture controls for teaching and remote lessons. The EW800ST doesn’t have those, but it does offer smart features that help improve efficiency.
We’ll start with a quick overview and highlights, then take a closer look at its special features and hardware. After that, we’ll dive into its picture quality and performance. On the last page, I’ll wrap everything up with pros and cons, plus some thoughts on how it compares to other projectors.

Overview
The BenQ EW300ST is a lamp-based projector with a lamp life of up to 10,000 hours in ECO mode. At full power, the lamp lasts about 5,000 hours.
| Lamp Mode | Hours | Estimated Use Before Replacement |
|---|---|---|
| Normal | 5,000 | About 4.6 years (based on 6 hours a day, 180-day school year) |
| ECO | 10,000 | About 9.3 years (based on 6 hours a day, 180-day school year) |
The BenQ EW800ST shows good color performance across different modes.
It has a WXGA resolution (1280 x 800), which is like 720p in the education world. This resolution is a bit lower than full HD and uses a 16:10 aspect ratio, not 16:9. So if you’re buying a new screen, make sure it supports 16:10, not 16:9.

For K-12 use, WXGA resolution offers enough clarity. In education, higher resolution is only needed in special cases. For example, video production, photography, yearbook, or graphic design classes might benefit from WUXGA resolution. Higher education may need WUXGA more often, but 4K is rarely necessary—except for medical videos, scientific rendering, simulations, architecture, film, and design work.
The BenQ EW800ST projects a WXGA resolution image.
With a brightness of 3300 lumens, it’s bright enough to handle most classroom lighting. In most cases, just dimming the lights a bit will give you a clear and sharp picture.
