What if the projector is connected to the blue screen?
1. Is the signal line plugged in?
First, check whether the signal line is plugged in. Sometimes the signal can't be transmitted normally because the line is loose or the interface is damaged. At this point, try plugging and unplugging the signal line again or replacing the signal line.
2. Resolution mismatch
If the display screen of the projector is too small or too large, it may be caused by the resolution mismatch between the computer and the projector. At this time, you need to enter the display settings of the computer and adjust the resolution to match the resolution of the computer and the projector.
3. Interface mismatch
If the projector and computer interface do not match, it will also lead to blue screen phenomenon. For example, the projector needs HDMI interface, but the computer only has VGA interface, or the computer needs DisplayPort interface, but the projector only has DVI interface. At this point, the adapter or interface cable needs to be replaced in order to connect the computer and projector correctly.
4. Hardware failure
If the blue screen still appears after checking all the above conditions, it may be caused by hardware failure, such as the expiration of projector lamp life or the failure of projector motherboard. At this time, it is necessary to contact the manufacturer or maintenance personnel for maintenance.
In short, if there is a blue screen phenomenon when the projector is connected, it needs to be checked one by one to find out the reason before solving the problem. If you are not sure how to do it, you'd better contact professional technicians for maintenance.
