You may still remember on 4th Jan, the Tronsmart team release a new update for their Tronsmart t1000 miracast adapter (version is 11281), and fix and improve a lot of things.
Now they release a new OTA update, version is 11283. Factory said they improve the connection with the windows 8.1 Tablet. I already tested this newest firmware with the Dell Venue 8 Pro tablet, the miracast function working like charm.
So we would love to suggest you guys update to the lastest 11283 version,Because the Tronsmart T1000 support OTA(over the air) upgrade technology, so you can just connect your Tronsmart T1000, go to settings, and click upgrade button.
If you met problem to update the firmware via OTA, here is the firmware, and you can upgrade it manually:
