LINKUP MSPRO4-769 Surface Pro 4 adapter review

A fitted adapter for Surface Pro 4

The LINKUP MSPRO4-769 is a purpose-built adapter for Microsoft Surface Pro 4. Its original page explicitly restricts physical compatibility to that model. It combines a Mini DisplayPort-to-HDMI path with USB data and card-reader expansion, using the tablet's neighboring USB and Mini DisplayPort connections.

This fitted arrangement is the deciding feature. Check the exact Surface model before considering the port list. The manufacturer gives 12.70 millimeters as the spacing between the USB and Mini DisplayPort ports and warns that a protective case can prevent the adapter from fitting. A similar-looking Surface is not enough to establish compatibility.

HDMI comes from the Mini DisplayPort path

The HDMI connection is documented up to 3840 by 2160 at 30 Hz, or 1920 by 1080 at 60 Hz. Choose the intended screen timing before purchase. A 4K monitor does not imply a 60 Hz 4K connection, and the original page does not establish two independent external screens from this single HDMI output.

The display path matters because this is not an ordinary USB data hub generating native video from USB-A alone. The separate Mini DisplayPort connection supplies the video route alongside the USB connection. Both the physical pairing and the host model must fit for the complete arrangement to make sense.

The Mini DisplayPort connection discussed here is on the host side. It should not be counted as a downstream full-size DisplayPort or Mini DisplayPort monitor socket. The documented output for the screen is HDMI, so include a suitable HDMI cable and check the monitor's chosen input.

Two data accessories and three card slots

LINKUP documents two USB-A data sockets rated at up to 5 Gbps. That can accommodate two appropriate accessories without continually unplugging them from the tablet. Think through the actual pair of devices, their plug widths and power needs before assuming that two sockets solve every peripheral requirement.

The rate is an advertised interface ceiling rather than a measured transfer result. Connected storage and the host still affect speed, and multiple activities share the data connection. The page does not provide a detailed combined peripheral power budget, so obtain confirmation for a demanding bus-powered setup.

The card arrangement is unusual: one full-size SD slot and two microSD slots. LINKUP explicitly says all three can be read simultaneously. One microSD slot has a retaining mechanism to keep its card seated. That makes this model worth examining for a workflow involving more than one small card, provided the exact tablet fit is satisfied.

Keep uncertain extras out of the purchase plan

A broad introductory bullet mentions Gigabit Ethernet, but the detailed feature and connection lists do not consistently include an Ethernet socket. This assessment leaves Ethernet unconfirmed. If wired networking is essential, request an exact port diagram or inspect the actual model before choosing it for that task.

The cited page also does not establish a laptop charging path, a supplied external power adapter or a per-port current allocation. Keep the Surface's charging routine separate in the planning checklist. A port-expansion adapter should not be assumed to take over a power role that its original documentation does not describe.

Choose it for the exact tablet and card workflow

For an existing Surface Pro 4, the combination of one documented HDMI output, two USB-A data sockets and concurrent access to three card slots can be useful. The fitted body is less forgiving than a loose cabled hub, so inspect the tablet's socket spacing and case clearance before relying on the arrangement.

Choose the MSPRO4-769 when the original Pro 4-only fit, screen timing and card workflow match the task. The exact LINKUP manufacturer page supplies these conditions. No later Surface compatibility, hands-on transfer result or undocumented power capability is claimed.
