Tronsmart T428 quad-core mini PC gets true 1080p Android 4.2 ROM update


The Tronsmart T428 has become a popular little mini PC, thanks mostly to its quick quad-core Rockchip RK3188 processor. It’s even no running a very early version of UbuntuĀ 12.04 via external MicroSD card, much like the original MK802 does albeit with no Wi-Fi or Bluetooth.

However, the original T428 ROM release only offer 720p desktop resolution option.

Well, the team at now have a new fully 1080p display ROM available for the T428 – but it comes with a warning.

Apparently, the increase in resolution causes the T428 to heat up – the recommendation is you put a ‘USB fan’ on the device to keep it cool. Mmm.

Anyway, the choice is up to you. You can get more details from the blog including download details and installation tips.

Given that the RK3188 is already manufactured on a tiny 28nanometre scale already, it looks as though getting native 1080p resolution from a quad-core mini TV stick is going to be problematic if you need to have a fan on it keeping it cool.

In the future, it’s more likely we’ll see Apple TV style mini PCs delivering true 1080p resolution with quad-core performance if simply to get the extra space to provide better cooling. It’s possible improved ROM efficiencies may help things but it’s a bit counter-productive if you need a fan to keep the device cool.
