Frequently Asked Questions
•
Q: Why does my CPU become busier after launching the BenQ EZ
QPresenter 2.0?
•
A: BenQ EZ QPresenter 2.0 counts on your PC CPU to encode the screen images to
reduce the data that needs to be transferred to the receiver. Hence there will be some
overhead to your PC. In general, for 4+ ranking PCs, it would need up to 30% of CPU
overhead to perform wireless display.
•
Q: Why can't I project my screen?
•
A: BenQ EZ QPresenter 2.0 needs to access the network connection at some point.
As a result, when your Anti-virus or network security software prompts you for
permission to allow the sender software to access the network, please grant access to
proceed, or choose "add rule" to the fire wall settings.
•
Q: Why does my display frame rate slow down?
•
A: BenQ EZ QPresenter 2.0 needs to encode display content while sending massive
real-time data to the projector.
i. PC: A dual core PC (excluding Atom processors) or Mac is required to encode
the screen images at 30FPS (Frame Per Second) speed. However, if you would

a. Use better media players, such as GOM player
b. Close all unused apps
c. Use a faster PC with Windows Experience Score higher than 4 (4+
recommended)

a. Move your laptop closer to the projector
b. Disable the "Minimum Power Consumption" option from the "Advanced Tab"
