It can generate UV maps at up to 8K resolution.

Take a look at UV Checker Map Maker, a free tool that lets you create custom checker maps developed by designer Jorge Valle. 

It allows you to choose from the existing palettes or create your own to then download the map at 1K, 2K, 4K, or 8K resolution. You can tweak the map's size, border thickness, microgrid's opacity and frequency, as well as the font and color of the text.
