ProBook 430 G7 docks: use its single DP 1.2 USB-C path

Which dock options should you consider?

For HP ProBook 430 G7, start with HP USB-C Dock G5 / 5TW10AA. HP names this exact notebook for the dock, whose rear HDMI and two DisplayPort sockets suit a one- or two-screen desk. The notebook has one USB-C 3.1 Gen 1 port with DisplayPort 1.2 and Power Delivery, so do not promise dual 4K or infer Thunderbolt performance. HP's later G5 table gives the safer DP 1.2 ceiling: two QHD60 screens or one 4K60 screen in high-resolution mode; begin with one FHD60 screen. HP also exact-lists Thunderbolt Dock 120W G2, but on this non-Thunderbolt host it is a USB-C fallback with lower documented display limits, not a Thunderbolt-speed setup.

Connect displays and power

Computer cable

Power the G5 with its matching 120 W supply and connect its attached 1 m host cable directly to the notebook's only USB-C port; remove extensions and intermediate hubs.

Displays

Use the G5's rear DisplayPort or HDMI sockets. Prove one FHD60 monitor and its selected input first, then add a second screen before raising resolution.

High-resolution mode

Treat two QHD60 or one 4K60 as HP-published DP 1.2 dock ceilings, not a tested desk result. High-resolution mode can reduce USB data performance because it reserves more lanes for video.

Power

The notebook is documented with 45 W and 65 W adapters, while the G5 can provide up to 100 W to supported HP hosts. Confirm Windows actually reports charging; the numbers alone do not prove negotiation.

First recovery steps by symptom

Nothing on the dock works

1. Confirm the dock's matching AC supply is connected before the notebook.
2. Reseat the fixed host cable in the notebook's single USB-C port with no extension or hub.
3. Test the notebook with its original 45 W or 65 W charger, then prove one USB device before reconnecting displays.

USB works but a display is blank

1. Disconnect every display except one, select that monitor's exact input and begin at 1920×1080 60 Hz.
2. Use one rear DisplayPort or HDMI output with a known-good cable, then compare a direct USB-C video connection.
3. Add the second screen only after the first is stable; enable high-resolution mode only when the requested mode needs it.

The notebook does not charge

1. Check Windows charging state rather than inferring power from working USB devices.
2. Reseat the host cable and temporarily remove high-draw accessories.
3. Compare with the original HP adapter; if it charges, keep it attached while updating the exact notebook BIOS and G5 firmware and isolating the dock power path.

Still unknown: HP's documents do not establish the installed graphics option, present BIOS and dock firmware, exact high-resolution-mode behavior, cable capability, monitor EDID, mixed resolutions, sleep/wake behavior or every current Windows build. The older model table and later Thunderbolt G2 USB-C fallback table conflict, so the lower later limit is used here. No physical ProBook 430 G7 desk was tested.
