Frequently Asked Questions - DX733 OPTOMA
How to replace the lamp of the OPTOMA DX733 projector?
Turn off the projector and unplug it. Let it cool. Open the lamp compartment (screw on the side). Replace the old lamp with a new one (ref. BL-FP200A). Close and plug in. Reset the lamp counter via the menu.
What is the maximum supported resolution?
The native resolution is XGA (1024 x 768). The projector accepts signals up to SXGA+ (1400 x 1050) compressed.
How to connect a computer to the projector?
Use a VGA (D-sub) cable to connect the computer to the 'VGA IN' input of the projector. Select the VGA source in the Input menu.
The projector does not turn on, what to do?
Check the power cable and socket. Make sure the lamp is properly installed. If the LED indicator flashes, consult the error code section in the manual.
How to clean the air filter?
Turn off and unplug the projector. Remove the filter cover on the side. Vacuum the dust or wash the filter with warm water. Dry completely before reinstalling.
Can the projector be used to watch movies?
Yes, the DX733 is suitable for movies thanks to its 3000 lumens brightness and 2000:1 contrast. Connect an HDMI source (Blu-ray player, HDMI stick) for better quality.
How to correct distorted image (keystone)?
Use automatic keystone correction (Display menu) or manual with the 'Keystone' buttons on the remote or control panel.
What is the recommended projection distance?
For a 100-inch diagonal image, place the projector about 3 meters from the screen. Consult the distance table in the manual for other sizes.
The projector turns off by itself, why?
This may be due to overheating (check ventilation and filter), a lamp at end of life, or the 'Auto Power Off' function enabled. Check the status indicators.
How to use the 3D function?
The projector supports DLP Link 3D with active glasses. Enable 3D mode in the menu. Make sure the source (Blu-ray player, PC) sends a compatible 3D signal.
