USB-C to Mini DisplayPort adapter

The Rocstor Y10A242A1 adapter connects a USB-C or Thunderbolt 3/4 device to a Mini DisplayPort monitor. It suits users who need to add an external display to a laptop, tablet or smartphone with a USB-C port.

5.9 inch cable and driverless design

A short integrated cable reduces strain on the host port while keeping the setup tidy. The adapter works without drivers on any operating system, so it is ready to use immediately after plugging it in.

8K 30Hz and 4K 120Hz maximum output

The adapter supports up to 3840 x 2160 at 60 Hz, 4K at 120 Hz with DSC, and 8K at 30 Hz. Buyers whose display requires higher refresh rates at 8K or 4K without DSC should verify compatibility before purchasing.

Questions about this item

Will the 5.9" cable or the 24-pin USB-C connector need replacement after daily plugging?

The 5.9" cable and 24-pin USB-C male connector are built for repeated insertion; no user-serviceable parts are inside, so normal use does not require scheduled replacement.

What resolution or refresh-rate ceiling appears first when driving a Mini DisplayPort monitor continuously?

The adapter caps at 8K 30 Hz, 4K 120 Hz, or 4K 60 Hz with DSC over the 20-pin Mini DisplayPort female port; sustained loads stay within those limits.

Does the aluminum housing get hot or draw extra power during all-day 4K 60 Hz output?

The driverless, OS-independent design draws only bus power from the USB-C port; the aluminum shell dissipates heat passively and stays at safe temperatures during continuous 4K 60 Hz use.
