The MK802 Mini PC is an inexpensive computer that's about the size of a large USB flash drive. It ships with Google Android 4.0 software, but as we've already seen it can also run Ubuntu, Puppy, and other Linux-based operating systems.
While the hardware can handle 1080p screen resolutions, out of the box the MK802 version of Android defaults to 720p. But the folks at the Miniand forums have figured out a way to enable support for higher resolution displays — at least when you're using Ubuntu.
The MK802 features an Allwinner A10 processor, Mali 400 graphics, 512MB to 1GB of RAM, and 4GB of built-in storage.
You can pick one up for well under $100 from AliExpress, eBay, or AsiaPads.
The simplest way to run Ubuntu is to load it on a microSD card and boot from that card.
Eventually Miniand plans to incorporate the 1080p fix into future disk images that you can load onto a microSD card. But for now, here's how to use one of the existing images to run Ubuntu Linux at 1080p on the MK802 Mini PC.
