Frequently Asked Questions - OP751RKe OPTOMA

How to turn the interactive display on and off?

To turn on, press the Power button on the front or on the remote control. The LED indicator turns blue. To turn off, press and hold the button for 3 seconds; the indicator turns red (standby mode). It is recommended to unplug the power cord if not in use for extended periods.

How to connect a computer to the display?

Use an HDMI or VGA cable. Plug one end into the display and the other into the computer. For VGA input, a separate audio cable is required. For touch, also connect a USB cable between the computer and the display's Touch USB port.

How to use the annotation function?

From the home screen, open the side toolbar by touching the left or right edge. Tap the annotation icon (pen). You can write, draw, highlight, and erase with your palm. Use color and thickness options. To capture the screen, tap the camera icon.

How to project the screen of my smartphone or computer?

Ensure the display and your device are on the same Wi-Fi network. On the display, open the Screen Sharing app. On your mobile, scan the QR code to install Share Sender and enter the displayed password. On PC, download Share Sender from the Optoma website. Once connected, your device's screen is projected.

How to adjust volume and activate silent mode?

From the Quick Settings menu (swipe up from the bottom of the screen or tap the Settings icon), drag the volume slider. To mute, enable the Mute option in audio settings. You can also use the VOL+ and VOL- buttons on the remote control.

How to activate the Low Blue Light function?

On the main page of the Quick Settings menu, toggle the Low Blue Light switch to the right. This function reduces eye strain during prolonged use. It is recommended to take regular breaks.

How to lock the screen to prevent unauthorized access?

Open the Screen Lock app from the home screen. If no password is set, tap 'Set PIN' and enter a 4-digit PIN. Confirm it. To lock the screen, relaunch the app; only those who know the PIN can unlock.

How to update the system?

Ensure the display is connected to the internet. Open the System Update app. If a new version is available, tap UPDATE. The firmware downloads automatically. Once downloaded, confirm to install. The display restarts twice. Do not turn off during the update.

What to do if the touch screen is not responding?

Check that there is no direct sunlight or intense light source on the screen. For an external device, ensure the USB cable is properly connected to the display's Touch USB port. If the problem persists, restart the display or contact customer service.

How to clean the screen safely?

First, unplug the power cord. Use a soft, dry, lint-free cloth to gently wipe the screen. Never use water, spray cleaners, or abrasive products. For the front frame, use a dry cloth. Never clean the interior yourself; contact a professional.
