FAQs
1� Does Qumi work with a personal computer, notebook or netbook?
Yes. Use the provided VGA cable or HDMI cable. The Qumi can connect to a PC, 
notebook or netbook if they have an appropriate HDMI or VGA port. To play audio, 
a separate 3.5mm stereo mini-jack audio cable is required to connect to the Qumi’s 
audio port.
2� Is it possible to connect the Qumi to a game console, such as a Microsof\
t® 
Xbox or Sony® PS3?
Yes. The Qumi can be used to display content from an Xbox or PS3 console. This can 
be done by connecting the HDMI cable from the game console to the Qumi.
3� Can the Qumi project content from a television?
Watching television content can be done by connecting a cable box, digital set-top-
box or satellite receiver because televisions are only able to produce images on its 
own screen. For example, if a cable box is used, it can be connected by an HDMI 
cable to the Qumi.
4� How can an iPad® connect to the Qumi?
An Apple® iPad to VGA converter cable is required. To connect it to the Qumi, connect 
the cable from the iPad to the converter. The VGA converter can then be connected 
to the Qumi. The output of the iPad will be properly resized to fit the Qumi’s native 
resolution and full screen view.  
						

							40
5� How are images from a digital camera or a USB storage device displayed?

Suite.
6� Which cable is required to video devices to the Qumi?

adapter cable (3.5mm mini plug and two RCA plugs). An RCA cable connected can

11� How long will the LED light source in the Qumi last and can it be replac\
ed?
The Qumi does not use a typical Qumi lamp. It uses a set of Light Emitti\
ng 
Diodes (LED) to illuminate and project images. LED’s have a greater lifespan than 
conventional lamps. Qumi LED’s are estimated to last for approximately 30,000 
hours. The lifespan of the LED depends on factors such as brightness, usage, 
environmental conditions. LED brightness can decrease over time. The LED module 
is not replaceable.
12� Why do I need to re-adjust the focus on my Qumi after it’s powered up?
For the best picture quality, adjustment of the focus ring may be necessary once the 
operational temperature has been met.
