Frequently Asked Questions
I lost my remote on my Qumi, how do I select inputs?
Press and hold the right or left arrow key for 3 seconds, and this will bring up the input menu. Use up and down arrow keys to select input. Press enter key.
I plug my computer in to the projector and I don’t get an image.
The projector has many input connectors. Each connector is labelled (HDMI 1, RGB 1 ....). Ensure the projector is switched to that input using the “Source” button on the projector. Also, the computer may require a toggle switch to turn on the output port. This is typically accomplished by holding down the “Fn” at the same time as a Function key. Each laptop manufacturer may use a different “function” key. Typically, it is F4 or F8. The symbol on the key is usually a laptop as well as a square. Please refer to your laptop manufacturers Users Guide for additional information.
My projector won’t turn on via an RS232 or IP command. If it is powered on, other commands work fine.
In the menu, go to Settings 2 menu, then Advanced 1 menu. Turn Low Power Mode to OFF.
How do I take care of my DLP?
Please refer to Warning and Precautions in the User's Manual.
Does HD really look better than SDTV?
Yes. HDTV has at least twice the linear resolution of standard-definition television (SDTV), thus allowing much more detail to be shown compared with analog television or regular DVD. In addition, the technical standards for broadcasting HDTV are also able to handle 16:9 aspect ratio pictures without using letterboxing or anamorphic stretching, thus further increasing the effective resolution for such content.

DLP® Technology
DLP® chipset-based projectors produce vivid images with digital clarity and precision. The DLP® chip uses millions of tiny mirrors to reflect all the colors of visible light to project a digital image onto a screen. DLP® technology delivers high contrast ratios and minimizes the gaps between pixels for bright, sharp pictures.
BrilliantColor from Texas Instruments is a multi-color processing technology that produces vibrant images. BrilliantColor technology uses up to six colors, instead of just the three primary colors, red, green and blue, to improve color accuracy and brightens secondary colors.
Filter-Free Design
DLP® technology allows manufacturers to create a filter-free projection design. Filter-free means significant savings and lower maintenance efforts over the projector's lifespan, which means a lower total cost of ownership for the projector.
Standard Warranty
2-Year Warranty on Parts and Labor.
