### ** Cov Ntawv Tseem Ceeb **
1. ** Kev sib xyaw ua kom lub cev **: Ob lub cables haum rau qub chaw nres nkoj, tab sis kev ua tau zoo caps ntawm tus qauv qis dua.
2. Ob daim ntawv pov thawj **: Tshawb cov ntawv cim rau ** USB 3.1 gen2 / pd / emark ** Daim duab uas xav tau yog qhov ua tau zoo.
3. ** Thunderbolt 3/4 **: Txawv los ntawm USB 3.1 (txhawb 40 Gbps).
Rau siab - cov ntaub ntawv ceev lossis video, ib txwm xaiv ** USB 3.1 gen2 ** (lossis tshiab} C cables.
