I would recommend another box, one with Android TV (not Android OS). There are several very good solutions, e.g. Google Chromecast with Google TV or an Nvidia Shield. Teleboy runs smoothly with Android TV boxes and the devices with Android TV usually have certification for 4K UHD, which means that UHD content such as Disney+ or Netflix can be displayed in full resolution.

A Google Chromecast with Google TV only costs around 80 francs, the Nvidia Shield would be a little more expensive, but offers better hardware. Another good solution would be the Mi Box S, which also runs perfectly with Teleboy. I have already used all three of these systems. The Nvidia Shield Pro is certainly the best model with the best technology, but the others all work as well (the Mi Box S couldn't do Dolby Vision, which the other models support).
