Saving energy saves money! Eco+ technology reduces the power consumption to as little as 30%. This intelligent feature also has a positive effect on the lamp life, increasing it up to 70% while lowering the total cost of ownership and reducing maintenance.
Auto power off
There may be instances when the projector is left running when not in use. To help save energy if the projector is left running and no source is detected, the "Auto Power Off" feature automatically turns off the projector after a set period of time.
Eco AV mute
Stay in control of your presentation with the Eco AV mute feature. Direct your audience's attention away from the screen by blanking the image when no longer needed. This also instantly reduces the power consumption to 30%, further prolonging the life of your lamp.

Short throw lens
The X305ST can project an impressive 60" diagonal image from just 77 cm from the screen. Standalone or wall mounted, the X305ST eliminates shadows on the screen and allows you to present with ease.
Bright, detailed and colorful projection
Grab your audience's attention with bright, vivid projected images thanks to the BrilliantColor technology incorporated within the X305ST. Preset display modes allow you to achieve a perfect image on a variety of surfaces including screens and interactive whiteboards
Clear, focused images
Lessons in the classroom and presentations in the boardroom demand sharp, flawless images. DarkChip3 technology from Texas Instruments produces a stunning 15000:1 contrast ratio for pin sharp graphics and crystal-clear text. Crisper whites and ultra-rich blacks make images come alive and text easier to read. To retain image clarity, Optoma projectors are designed with DLP technology preventing degradation over time to give consistent pixel performance.
Dynamic discovery protocol is incorporated into the X305ST. This feature allows for easy installation with AMX control systems.
Direct power on
Start up time is significantly reduced as standby mode is bypassed when the power cable is inserted into an active power outlet. This eliminates the need to use the 'Power' button on the remote control or the projector keypad.
Once enabled, prevents unauthorized adjustments ensuring the projector can only be controlled via the remote control.
