What should I do if there is no signal when connecting to the projector in win10?

Solution:

1. The projector has a signal output to the projection cloth, which means there is no problem with the projector; the input button on the projector allows the projector to automatically search for computer signals , "A signal output" is the output of VGA signal (output signal of computer, etc.). "No Memory Stick" has no effect on the computer output signal to the projection.

2. Confirm that there is no problem with the computer and switch on the computer.

3. Restart the computer and see if the projector can detect the computer signal.

4. Look at the resolution of the computer monitor. If it is too high, it may exceed the display range of the projector and cannot be displayed, so it is generally 1024*768.

5. Look at the refresh frequency of the graphics card. The refresh frequency of the graphics card may also affect the normal output to the projector. It is generally set to 60MHZ.

6. Right-click on a blank area of ​​the desktop, select "Properties", then select "Settings", and then deselect "Extend Windows desktop to monitor".

7. After all the above tests, it still didn’t work. Finally, the technician asked me to modify the projector’s menu. Press menu to enter the projector's menu, then move to the third item (a small box shape), then change the A signal output to "Computer", exit the menu after setting, and then press the input key to search for the signal.
