Spacedesk documents a setup with a Driver on the Windows computer and a Viewer on the secondary device, and its current download page lists an Amazon Viewer. Whether that Viewer is available for and runs on your particular Fire depends on the tablet model and software version.
First, identify the Fire tablet
“Kindle Fire” can refer to many generations, so a seven-year age estimate is not enough to identify the hardware. Check the tablet’s model name or model code and its Fire OS version before trying to install anything.

For example, Amazon lists the Fire 7 (2017, 7th Gen) as a 7-inch tablet with a 1024 × 600 display, 1 GB of RAM, Fire OS 5, and model code KFAUWI. Those specifications apply to that model, not every Fire tablet of a similar age. See Amazon’s Fire model specifications and device specifications overview.

How a Fire tablet can act as a PC display
Spacedesk’s documented arrangement uses two components: its Driver, including the network display server and display drivers, runs on the primary Windows computer; its Viewer runs on the secondary device. The devices connect over a network, which may involve a router, switch, or access point, or a direct connection. Spacedesk describes its software as turning mobile devices into an additional extension display for Windows machines on its download page and explains the arrangement in its setup manual.

The download page currently lists an Amazon Viewer, making spacedesk a plausible option to investigate. That listing does not confirm that the current app can be installed on every older Fire model, or that it will work on an unidentified tablet. Check the supported app source for your device and its OS version before proceeding; app availability and screens can vary.
General setup route
The official documentation supports the Driver-and-Viewer approach, but it does not verify each menu or compatibility for a specific legacy Fire tablet. Treat these as general steps rather than a guarantee of success.

- Identify the tablet. Find its model name or code and Fire OS version in the device settings, then check whether the spacedesk Viewer is available for that model in its supported app source.
- Install the Windows Driver. On the computer you want to extend, use the Driver download from the spacedesk download page.
- Connect both devices to a usable network. Spacedesk documents network connections, including connections through a router, switch, or access point and direct connections. Its general product information also mentions USB and network cable, but the available evidence does not establish wired USB display support for an unspecified Fire tablet.
- Open the Viewer and connect to the Windows computer. Follow the app’s available connection options; interface labels may differ by version.
- Choose Extend in Windows display settings if you want a separate desktop. A duplicate mirrors the same desktop; an extended display gives Windows another desktop area to place windows on.
Do not confuse a second monitor with Fire screen mirroring
These features send video in different directions. Spacedesk’s Viewer is intended to receive an additional Windows display on the secondary device. Amazon’s Fire tablet screen-mirroring instructions describe sending the tablet’s own screen and audio to another compatible display, and specify Fire OS 8 or higher. That mirroring feature does not, by itself, make the tablet a receiving monitor for a computer.

What to expect from an older tablet
Compatibility is the key uncertainty: the current Amazon Viewer listing does not prove installation or operation on a particular legacy Fire. The available official information also does not establish latency, frame rate, reliability, or performance on the tablet described by age alone, so those results should not be assumed.
If the Viewer is unavailable or will not connect, confirm the model and OS first, then check the app’s compatibility and the spacedesk Driver/Viewer setup. The evidence here does not establish a USB workaround for a Fire tablet. Amazon’s instructions to select File Transfer on Fire OS 7 are part of its ADB developer connection procedure, not evidence of USB monitor support.

Is it useful as a second screen?
If your Fire model can run the Viewer and connect successfully, an extra screen could be handy for a reference page, chat window, music controls, or other secondary content. A 7-inch, 1024 × 600 screen such as the Fire 7 (2017) has limited space, so it is a better fit for a small companion panel than for work that needs a large, detailed desktop. A stand is optional; check the tablet’s dimensions and case fit before choosing one.
