If you are showing videos it is best to go for WXGA (widescreen) resolution. However, laptops will be at least XGA resolution and you can still receive a clear, crisp image which is suitable for PowerPoint, spreadsheets, images and short videos. This projector has a standard throw ratio. The connectivity is great too as there is a VGA port, two HDMI connections so you can connect to most modern sources and show your content in high definition. There is a USB port to allow you to present PC-free. The added 10W speaker will be powerful to present to a medium size audience without any additional audio. Another added feature is the keystone correction which means if you are slightly offset, you can still project in the middle of the screen. It also features corner fit. The BENQ MX731 has a bright 4000 lumens to fit your projection needs for medium to large-sized venues. You will be able to present with the lights on and blinds open throughout the day. The BENQ MX731 keeps power consumption to a minimum with 0.5W in standby mode helping to lower energy costs. Overall, this is a fantastic projector for education and business needs and BENQ are one of the top manufacturers due to all it’s cost effective features.
