HP G5: ports, power and screen checks
| Check | For this setup |
|---|
| Computer cable | The attached G5 USB-C cable goes to the laptop’s video-capable USB-C port. |
|---|
| Screen cables | Use rear HDMI or DisplayPort. The front USB-C socket is for data and 15 W accessory power, not a monitor. |
|---|
| Two Full HD screens | Listed in every G5 bandwidth column, assuming the host supports the display count. Confirm the exact laptop configuration and OS. |
|---|
| Two 4K60 screens | Require DP 1.3/1.4 in high-resolution mode, or DP 1.4 with DSC in the default mode. A USB-C socket alone establishes neither. |
|---|
| Three 4K60 screens | Only listed with DP 1.4 DSC in high-resolution mode; all three rear video outputs are used. |
|---|
| Power | Up to 100 W to supported HP hosts. A workstation requiring more needs separate supported power. |
|---|
