4000 Lumens 

While it’s a little lower than the MW560N, 4000 lumens is still bright enough for most meeting rooms, classrooms, or small conference areas, especially if there is some ambient light. It should still provide a clear, bright image in moderate lighting conditions.

XGA Resolution 

This is a step down from WXGA (1280x800) in terms of resolution. XGA typically has a resolution of 1024x768, which is still fine for text-heavy presentations or standard slide decks, but it’s not as sharp as WXGA or Full HD. If you're showing high-res images or videos, you may notice a slight drop in clarity compared to higher-resolution projectors.

Portable Design 

The EX605 is built for portability, making it easy to move around from room to room or take on the go for different locations, which is a big plus for people who need a versatile projector for different types of settings.

Smart Features 

The "Smart" in the name likely refers to features such as wireless connectivity, smart device compatibility, or easy setup. BenQ often includes user-friendly features like this, but it would be worth checking for specific smart capabilities like app integration or remote control options.

Lamp Life and Energy Efficiency 

If it follows similar trends as other BenQ models, it likely offers a long lamp life (often around 10,000–15,000 hours in eco modes), but this would be something to confirm based on the exact model details.

Color Performance 

BenQ projectors typically have good color reproduction, often using their proprietary "Colorific" technology, which enhances color accuracy, so your presentations will likely look vivid and accurate.

White and Sleek Design 

The white color can be a nice, clean aesthetic choice that blends well in professional environments, and the compact size makes it less intrusive when setting up or moving around.
