Need help?
Do you have a question about the HI-04 and is the answer not in the manual?
Questions and answers
Can I use an app if there is no remote?
Yes, you can use the DR.J HI-04 without a remote control. The remote control allows for remote operation, but the projector should still have onboard buttons or controls for basic functions.

How do I make it stay on a picture for a longer
To make the DR. J HI-04 projector stay on a picture for a longer time, ensure that a stable video or image source is connected through HDMI or AV. If the projector displays "No Signal," it will not stay on a picture. Also, check that the source device (like an iPad) is active and not going to sleep or turning off the display.

I just bought a projector and would like to connect it to my phone so i can project images or video from my phone. It will play the sound but the images will not project. Is there a setting? I can't figure out. Also I've tried to connect to my lap top but it is still doing the same thing. Actually the lap top will project the screen saver but nothing else. Can you please help me?
To connect the Dr. J HI-04 projector to your phone and laptop:
1. For a Laptop (Windows or Mac):
- Using HDMI Cable:
- Plug one end of an HDMI cable into your laptop's HDMI port.
- Connect the other end to the HDMI port on the left side of the projector.
- If your laptop lacks an HDMI port, use an appropriate adapter.
- Select the "Input Source" on the projector and choose "HDMI."
2. For a Phone or Tablet:
- Use an HDMI to Lightning cable (for iPhones) or an HDMI to USB-C adapter (for Android devices).
- Connect the HDMI cable to the adapter, and then to the HDMI port on the projector.
- Ensure the adapter is compatible with your phone or tablet.
If using a VGA cable for the laptop, you will also need a 3.5mm audio cable to connect audio, as VGA does not support audio.

Why is it projecting a white screen only? No color, no menu, just white box.
I have power the red light is on.. but the projector itself will not power on
There was an erratic power supply at my house and my dr Q mini projector was plugged so it was affected and now not even the power indicator is coming on…what may be the problem because I tried to take it apart to check for any burnt parts but I didn’t spot anything. What can be the problem ?
Does the Dr J Professional projector have an option to hook up to external speakers?
