Reasons For

Acer K137 DELL M115HD
8 Reasons For
17% Quieter Noise Level
The Acer K137 is a 31dB projector. That's 5dB quieter than the DELL M115HD (36dB).

The noise level of the projector is the amount of noise that the projector makes (caused by the cooling fan inside the projector) when it is running.

A lower noise level means that the projector will be quieter when it is running. This means that you will be able to appreciate the quieter parts of films better without the background noise of the projector running.

Read more Read less | Edit
250 ANSI Lumens Brighter Projector Brightness
The Acer K137 has a projector brightness of 700 ANSI lumens, however the DELL M115HD is only a 450 ANSI lumens brightness projector (250 ANSI lumens dimmer).

This is how bright the bulb in the projector is, measured in 'lumens'.

A brighter bulb means that the projector will be seen clearer, and can project to surfaces father away without appearing too dark.

Read more Read less | Edit

The Acer K137 supports 3D, but the DELL M115HD does not support 3D.

3D compatible projectors are able to display 3D content. Most projectors will require you to wear special glasses in order to view the 3D effect.

A 3D projector allows you to view the huge range of 3D films and content that is now available.

Read more Read less | Edit
Handheld Remote Control
