What Microsoft Does Not Publish for This Product

The following are commonly asked about but are not stated on any current official Microsoft source for this product, so SourceIT does not quote them: refresh rate, wireless range for the 4K model, dimensions, weight, cable length and a manufacturer warranty term. We would rather leave a field blank than print a figure we cannot substantiate.

Microsoft has withdrawn this product from its catalogue. Its Store product identifier returns a not-found error in both the United States and United Kingdom markets, and every Store address form fails or redirects. Only Microsoft’s support documentation survives, and every figure on this page is quoted from it.

Microsoft has withdrawn its own-brand PC accessory catalogue. The microsoft.com/accessories product pages for this range now redirect to Microsoft's general hardware-warranty and PC-accessories support pages, and the Microsoft Store Singapore PC-accessories collection returns no results. Microsoft has published no formal discontinuation notice for this product; the evidence is the removal of the pages themselves.

Do not confuse this with the original Wireless Display Adapter. Microsoft still publishes a complete specification for that separate, non-4K product — including a range of up to 7 m, dimensions of 103.5 × 22.0 × 11.0 mm, a weight of 33.1 g, a 300 mm cable and a 1-year limited warranty. Those figures belong to a different adapter and none of them have been carried onto this page. A range figure of roughly 7 m also appears in a shared troubleshooting article, in passages about the standard adapter; we have not attributed it to the 4K model.

This listing shows zero inventory in our system. Contact SourceIT for the current stock position and lead time before you raise a purchase order.

Warranty Position

Microsoft no longer publishes a warranty term for this product. Microsoft's current PC accessory warranty page states only that the accessory "comes with a 'limited hardware warranty' depending on the device" and directs the buyer to check their proof of purchase to identify the warranty period. SourceIT therefore does not quote a manufacturer term for this item. Ask our team to confirm the warranty position in writing before you order.

The local warranty named in the heading of this listing is SourceIT's own commercial term, not a figure published by Microsoft. Ask our team to confirm the term in writing with your quotation.

Microsoft publishes support for Miracast-enabled Windows 10 and Windows 11 devices and Android devices, with Android support specific to the 4K model. There is no published support for iPhone, iPad or macOS, which do not use Miracast.

Check these network conditions before ordering for a corporate environment. Microsoft publishes that the network must use WPA, WPA2 or WPA3; that enterprise authentication is not supported; that the adapter does not work behind a proxy server; and that the 2.4 GHz band must be enabled when pairing. Many corporate wireless networks use enterprise authentication as standard, which rules this adapter out.

The adapter draws power over USB and requires at least 5 W, or 5 V at 1 A. A low-power USB service port on an older display or projector may not supply that, in which case use a mains USB supply.

HDCP must be enabled in the casting application. If the screen goes black on protected content, that is the usual cause.

Microsoft’s product listing for this adapter has been removed from its catalogue, so the support documentation above is the only surviving official source.

Does it really do 4K?

Yes, and Microsoft states that this is the only model in the range that can: “Only the Microsoft 4K Wireless Display Adapter can display in 4K.” The display must support 3840×2160 or higher.

Will it work on our corporate Wi-Fi?

Check first. Microsoft publishes that the network must use WPA, WPA2 or WPA3, that enterprise authentication is not supported, and that the adapter does not work behind a proxy server. Many corporate networks use enterprise authentication, which rules it out. Ask us and we will review your wireless design before you order in quantity.

Does it work with an iPhone, iPad or Mac?

No. It uses Miracast, and Apple devices do not. Microsoft publishes support for Miracast-enabled Windows 10 and Windows 11 devices and Android devices only.

Does it work with Android?

Yes, and Microsoft notes that Android support is specific to the 4K model rather than to the range as a whole.

What is the wireless range?

Microsoft does not publish a range figure for the 4K model. A figure of roughly 7 m appears in a shared troubleshooting article in passages about the standard, non-4K adapter, and we have not attributed it to this product.

How is it powered?

Over USB, requiring at least 5 W, or 5 V at 1 A. A low-power USB service port on an older display may not be sufficient; use a mains USB supply in that case.

What warranty applies?

Microsoft publishes no warranty term for the 4K model. It does publish a one-year limited warranty for the separate, original non-4K Wireless Display Adapter, but that is a different product and we do not extend its term to this one. SourceIT supplies this adapter with local support and a GST invoice. The local warranty named in the heading of this listing is SourceIT's own commercial term, not a figure published by Microsoft. Ask our team to confirm the term in writing with your quotation.
