When we connect a projector with a computer, we usually have an interface, that is, VGA interface. We can connect it directly, so we can use it. When we use it, we need to switch the projector mode first. Generally, you can press a key FN+F 1~F 12 for a long time. You can try one by one, depending on the brand of computer you use.
When the computer is connected to the projector, it can't be used normally, especially if it doesn't display. At this time, you need to check the graphics card driver. Generally, the situation of not displaying is mostly caused by the graphics card driver. As long as we install the graphics card driver, there will be no problem. It should be noted here that it is best to install the official driver of your own brand.
After we install the graphics card driver, if the computer still can't display with the projector, it is generally closely related to the resolution. Everyone should adjust the resolution. The specific resolution model is different, and we can adjust it according to our own computer.
How to install projector equipment
1, hanger installation
The upper part of the hanger is a square frame with eight through holes with a diameter of 6mm, which are the installation holes connecting the hanger and the upper fixed parts of the ceiling. The distance between the mounting base surface of the fixture and the ceiling surface depends on whether the projector is hidden in the ceiling. If hidden inside the ceiling, this distance should be greater than the sum of the height of the contracted hanger and the height of the projector itself.
2, projector installation
The projector is fixed with a universal hook at the bottom of the hook. According to the size of the projector, adjust the pull rod for fixing the universal hook to connect the projector with it.
3. Electrical connection
Connect the power line and control line correctly according to the given wiring diagram. The installation method of various wires of the projector itself is as follows: Put several small rings on the two wire ropes respectively. When the hanger reaches the maximum stroke, the conductor of the projector is fixedly connected with the small ring by plastic tie, and then the conductor is connected to two steel wires in a zigzag shape from bottom to top. When the hanger moves up and down, various wires of the projector will move between the two steel wires.
4, adjust the hanger height
There are two travel switches on the upper part of the hanger to control the upper and lower positions of the hanger respectively. Loosen the upper bolt, move the travel switch left and right according to the mark, adjust the position of the hanger, and then tighten the small bolt.
