Answer: False.
Answer analysis: The correctness of the statement that "sending cards and receiving cards from different manufacturers can be mixed and matched" depends on multiple factors, mainly including technical compatibility, communication protocols, interface standards, and cooperation between manufacturers.
1. Technical compatibility: Sending cards and receiving cards produced by different manufacturers may use different technical architectures and circuit designs, which may lead to differences in electrical characteristics, signal processing methods, etc. If these differences cannot be effectively bridged or compatible, then mixed use may lead to unstable signal transmission, poor display effects, and even equipment damage.
2. Communication protocol: Data transmission and control between sending cards and receiving cards require a specific communication protocol. If products from different manufacturers use different communication protocols or the protocol versions are incompatible, they will not be able to communicate effectively, and thus cannot achieve normal display functions.
3. Interface standard: The interface between sending cards and receiving cards is also an important factor affecting mixed use. If there are differences in the physical shape, pin definition, electrical characteristics, etc. of the interface, they will not be able to be directly connected together, or even if they can be connected, it will cause abnormal signal transmission.
4. Cooperation between manufacturers: Some manufacturers may provide compatibility support with other manufacturers' products or launch special adapters to achieve mixed use of different brands of products. However, this usually requires cooperation and negotiation between manufacturers, and may be limited by various factors such as technology, cost, and market strategy.
In summary, although in theory, it is possible to mix and match sending cards and receiving cards from different manufacturers in some way, in actual operation, due to the limitations of various factors such as technical compatibility, communication protocols, interface standards, and cooperation between manufacturers, the possibility of such mixed use is relatively small.
Therefore, for the statement "sending cards and receiving cards from different manufacturers can be mixed and used", we cannot simply think it is right or wrong, but should analyze and judge it according to the specific situation. In most cases, in order to ensure the stability and reliability of the system, it is recommended that users choose products of the same brand or products that have been tested for compatibility for use.
