Hdmi projection shows incomplete photos.

When the screen is projected, the TV only has sound, and the picture is gone? This may be caused by the following reasons.

Connection problem

First, check the connection between the TV and the projection device. Cable projection screen? Ensure that cables such as HDMI and VGA are plugged in tightly. Wireless projection screen? Make sure that devices such as Chromecast TV stick and Apple TV are connected to the TV and the Wi-Fi network is connected!

Resolution mismatch

The resolution of TV and projection equipment must match the numbers! Different resolutions may cause the picture not to be displayed. Try setting it to the same resolution to see if the problem is solved.

Audio and video formats are incompatible.

The file format of the projection screen must be compatible with the device. Look at the manual or official website to confirm which formats are supported, and then try again.

Software setup problem

You should also check the settings of the screen projection device. These options, such as screen mirroring and extended screen, must be selected correctly to succeed.

Equipment failure

If all the above are all right, there may be something wrong with the TV or the screen projection device itself. Try changing the TV or equipment to see what the problem is.

after service

Finally, if the problem is still not solved, remember to contact after-sales or professional maintenance personnel, and they will help you fix it!
