How much does the HD line length of the projector generally choose?

The choice of the length of the projector HD line depends mainly on the distance between the projector and the signal source in the use scenario, and also consider factors such as the wiring mode and signal quality. 

The following are some recommended lengths in common scenarios:

• Home theater: If you build a home theater in the living room, the projector is usually installed behind the sofa or on the ceiling, the signal source (such as Blu-ray player, TV box, etc.) is placed near the TV cabinet,

the general distance is about 3-5 meters, in this case, choose 3 meters or 5 meters of HD line is more appropriate. If you need to place the projector in the corner of the room, the distance from the signal source may

reach 8-10 meters, you need to choose a high-definition line of 8 meters or 10 meters, but be aware that long-distance transmission may lead to signal attenuation, you can choose a high-definition line with better 

quality and signal amplification.

• Conference room: The projector in the conference room is generally installed on the front ceiling, while the signal source such as the computer is on the table at the back of the conference room, which may be 5-10 

meters away or even further. At this time, it is recommended to choose the HD line according to the actual measured distance, the distance of 5-8 meters can choose the conventional HD line, more than 8 meters is the

best choice of reliable quality, high-definition line with signal enhancement function to ensure the quality of the projection picture.

• Classroom: The projector in the classroom is usually installed on the ceiling near the podium, while the computer and other equipment on the podium, relatively close, generally 2-3 meters of high-definition line is enough.

 However, if the classroom is large, the projector needs to be installed at the back of the classroom to achieve a better projection effect, and 5-8 meters of HD line may be required at this time.

When choosing the length of the HD cable, try to avoid being too long or too short. Too long HD cable will not only increase the cost, but also may affect the picture quality due to signal attenuation; If it is too short, the 

connection between devices cannot be met, resulting in inconvenient installation. If you are not sure about the specific length, you can first carry out field measurement, and then select the appropriate length of high-definition

line according to the measurement results.
