Frequently Asked Questions - DDA120 OPTOMA
How to replace the lamp of the Optoma DDA120 projector?
Turn off the projector and unplug it. Let it cool for 30 minutes. Open the lamp compartment on the side, remove the screws, replace the lamp with a new one (original Optoma reference), then close it. Reset the lamp counter in the menu.
How to clean the air filter?
Use a low-power vacuum cleaner to suck dust from the filter. Do not wash the filter with water. Put it back after cleaning. Perform this operation approximately every 500 hours of use.
The projected image is blurry, what should I do?
Check the focus by turning the focus ring on the lens. Also adjust the projection distance and keystone correction if necessary. Make sure the screen is clean.
Can I connect a smartphone to the projector?
Yes, if your smartphone supports video output via HDMI adapter (MHL) or via a wireless adapter (not included). Use the HDMI port on the projector.
Why does the projector not turn on?
Check that the power cord is properly plugged in and that the outlet works. The power indicator should be on. If the indicator flashes, the lamp may be near the end of its life or there is an internal fault.
What is the recommended projection distance?
For a 100-inch diagonal image, place the projector about 3 meters from the screen. Use the zoom to adjust the size.
How to reset factory settings?
Go to the OSD menu, select 'Settings' then 'Reset'. Confirm with 'Yes'. The projector will restart.
Can I use the projector with a game console?
Yes, connect the console via an HDMI cable. The projector supports signals up to 1080p. Enable game mode in the menu to reduce input lag.
How to lock the projector to prevent unauthorized use?
In the 'Security' menu, enable password lock. Set a 4-digit password. The projector will request this code at each power-on.
What is the warranty for the Optoma DDA120 projector?
The standard warranty is 2 years for the projector and 90 days for the lamp. Keep the invoice for any claim.
