Hi Antonella, thanks for bringing this up. Let’s carefully check a few things together so we can narrow down the cause and fix it.
To start, can you confirm these for me:
- Does the projector work with another device, for example, a DVD player or another laptop via HDMI?
- On your Asus laptop, do other external monitors or TVs work when connected through HDMI?
- When you connect the projector, do you hear the “device connected” sound or see any flicker on the laptop?
- Are you using any HDMI adapter or docking station, or is it a direct HDMI-to-HDMI connection?
- Is the projector set to the correct input source (HDMI instead of USB or AV)?
In the meantime, here are the steps you can try
Step 1. Check Display Settings
Press Windows + P and cycle through Duplicate, Extend, and Second screen only.
Open Settings > System > Display and check if a second screen is listed. If not, click “Detect.”
Step 2. Test the HDMI Cable and Port
Try a different HDMI cable.
If your laptop has more than one HDMI or USB-C port, test each one.
Step 3. Update Graphics and Chipset Drivers
On your Asus VivoBook, open Device Manager.
Expand Display adapters.
Right-click your GPU (Intel/AMD/NVIDIA) and select Update driver. You can also install the graphics and chipset driver from the ASUS support site. After installation, restart your computer.
Step 4. Check Projector Mode
Make sure the Apeman projector is set to HDMI input.
If using USB, note that most projectors only use USB for power, not video input. HDMI is the correct way to connect.
Step 5. Restart Both Devices
Power off the projector and unplug it.
Restart your laptop.
Power the projector back on, select the HDMI input, then connect the cable.
Step 6. Perform a Clean Boot to rule out third-party software blocking the setup.
Press Win + R, type msconfig, and hit Enter
Go to the Services tab, check "Hide all Microsoft services," then click "Disable all."
Go to the Startup tab and click Open Task Manager
Disable all listed startup items
If none of these steps work, it could be either:
A faulty HDMI port on the laptop,
A compatibility issue between the projector and the laptop’s output format,
Or a problem with the projector itself.
Let me know the answers to the questions above and how these steps go.
All the best!
