Frequently Asked Questions - V6820i ACER

What is the native resolution of the Acer V6820i projector?

The native resolution is 3840 x 2160 (4K UHD), supporting up to 4K (4120x2160) and UXGA.

How do I replace the lamp on the V6820i?

Turn off the projector and let it cool for at least 30 minutes. Disconnect power, remove the lamp cover screw, push and lift the cover, remove the protector, unscrew the lamp module, pull out the plug, lift the handle, and pull out the module. Reverse steps to install a new lamp. Reset the Lamp Hour Reset in the Settings menu after replacement.

Why does my projected image have no signal?

Ensure the power and signal cables are securely connected. Check that the correct source is selected via the Source button. If multiple sources are connected, cycle through them. Verify the lens cap is removed. If using a computer, check the display resolution is ≤ WUXGA-RB (1920x1200).

How can I adjust the vertical position of the projected image?

Use the manual lens shift control ring on the projector to adjust the image vertically up to 15% of the image height. This allows repositioning without moving the projector.

Can I connect the projector to a wireless network?

Yes, insert a WiFi dongle into the USB port, then go to Settings > Network > Wireless Setting to enable WiFi and connect to an available network. For LAN control, use the RJ45 port.

What is the ECO mode and how does it affect lamp life?

ECO mode lowers power consumption, dims the lamp, and reduces fan noise, extending lamp life. Enable it via the Color menu under ECO Mode.

How do I enable 3D on the V6820i?

Go to the 3D menu and select 'On'. For HDMI 1.4a 3D signals, use Auto 3D. Choose the 3D format (e.g., Frame Packing, Side by Side) if needed. Wear DLP 3D glasses and adjust 3D L/R Invert if overlapping is seen.

What should I do if the projector overheats?

An onscreen message will appear: 'Projector Overheated. Lamp will automatically turn off soon.' Let the projector cool. Ensure ambient temperature is between 5°C and 40°C, check that air inlets/outlets are not blocked, clean the filter, and enable High Altitude mode if operating at high altitudes.

How do I clean the projector?

Unplug the projector before cleaning. Use a damp cloth (not liquid cleaners) to wipe the exterior. Do not block ventilation slots. For the lens, use a soft cloth. Do not use abrasive cleaners or solvents.

What is the maximum projection distance?

The maximum projection distance is 8.0 meters (26.4 feet) for a screen size up to 300 inches diagonal. The recommended distance varies based on desired image size; refer to the distance table in the manual.

Adjusting the Projected Image

Adjusting the Height of Projected Image

The projector is equipped with elevator feet for adjusting the height of image.

To raise/lower the image:

Use Tilt adjusting wheel to fine-tune the display angle.

How to optimize image size and distance

Consult the table below to find the optimal image sizes achievable when the projector is positioned at a desired distance from the screen.

If the projector is 2 m from the screen, good image quality is possible for image sizes between 57" and 75".

Note: Remind as below figure, the space of 98 cm height is required when located at 2 m distance.

How to get a preferred image position by adjusting lens shift

The projector is equipped with lens shift for adjusting the position of projected image up and down without requiring you to physically move the projector.

Note: The figures shown in this section are for reference only not approximate value. The figures between units can be different due to assembly tolerance.

The vertical height can be adjusted between 0% and 15% of the image height. (The typical vertical image offset is fixed at 15% of the image height above the center of the projector lens.)

Offset max=V x 15%
