1, performance: single display usually has strong graphics processing ability, while collective display is relatively weak. Single monitor can provide better game and multimedia experience, while collective monitor is more suitable for daily use.

2. Memory: Single monitors usually have independent memory, while collective monitors enjoy system memory. Independent video memory can provide better graphics performance and stability, but it will also increase the cost.

3. Power consumption: A single display usually requires high power consumption, while a collective display is relatively low. This means that using a single monitor may increase the heat dissipation and power consumption of the system.

4. Price: Independent monitors are usually more expensive than integrated monitors because they require higher technical costs and more complicated circuit design.
