Plugging this in provided a USB mounted device containing driver installers and a PDF with links to a github page with subdirectory "MindShow/USBDisplay" to obtain more recent versions. Obviously you should check these with virustotal before running, and while there is a XP version there was unfortunately no linux support and no extra display showed up in Ubuntu. Mac and Android options are there though. Note that it was reported as a USB 2.0 device, not USB 3.0 as claimed. At least Windows installation was straightforward, with a tray icon available to indicate attached devices of this type. Supported resolutions included the usual ones up to 1920x1080 full HD.

Did not work

This is good for dealing with ancient business projectors that don't have anything other than a VGA input (and maybe composite video, because they're OLD). There's still enough knocking about that, should you find yourself having to do a presentation, it's worth having a way of getting a VGA output on your 20 years younger laptop.Getting this going was initially a mystery, because there's nothing but the adaptor in the packaging - no instructions or anything - but fortunately the adaptor presents itself as a flash drive as well as a display adaptor. And audio output, despite having no actual way of outputting audio, which could cause problems. Anyway, the flash drive has a PDF readme, which doesn't really explain much other than recommending disabling or uninstalling your antivirus. Lol nope.Unlike the USB C to HDMI adaptors, which rely on the internal mechanisms of USB C to redirect graphics directly from the GPU to the display, to go from USB A to any form of display requires a lot more effort. It's not plug-n-play, hence the required driver. Sadly the driver isn't available from anywhere other than the flash drive (and it's possible to delete the files on that) - no Windows Update support. There's also an Android .apk file for if you really want to fly by the seat of your pants, and a MacOS driver that almost certainly doesn't work any more.For the price it's quite good, but the sketchiness of the instructions and installation marks it down.
