The brilliant contrast ratio means the Optoma S334E will show even the darker images in more detail. It will produce radiant colours due to the brightness of this projector; it will be able to cope with bright rooms so you will not have to worry about closing the curtains or turning the lights off. This projector has a HDMI input which is great as you can connect to HD sources. It also has USB for PC-free presentations. As a low cost projector, this is ideal for simple PowerPoint presentations and simple images but not much more than that. To help save energy, the “Auto Power Off” feature automatically turns off the projector after a set period of time if it is not being used.
