Xiaomi M1805D1SG โ€“ What is the model of the TV?

If you stumble upon the mysterious Xiaomi M1805D1SG designation in search of a new TV, or try to figure out what kind of device it is already in your home, you have come to the right place. This model is one that often raises questions from users because of its non-obvious markings. Unlike the usual Mi TV or Redmi Smart TV series, the M1805D1SG code does not reveal either the diagonal, the year of release, or the key chips at once.

In this article, we will take a closer look at what the Xiaomi M1805D1SG is all about, from technical specifications to operational nuances, how it differs from other Xiaomi TVs, what its strengths and weaknesses are, and how to set it up correctly. We will focus on compatibility with Mi Home and Google Assistant, the relevance of firmware and the typical problems faced by owners.

Spoiler: The M1805D1SG is not just a random set of letters and numbers, but part of Xiaomiโ€™s internal notation system that helps identify the device in service centers and databases. And yes, this TV is still available for purchase โ€” but with reservations, which we will discuss below.

Decoding the model: what does the M1805D1SG mean?

The M1805D1SG marking follows Xiaomiโ€™s internal logic, where each letter and number carries a meaning.

  • ๐Ÿ”น M is a prefix denoting membership in the Mi line TV (as opposed to Redmi or POCO).
  • ๐Ÿ”น 1805 - year and month of model development: May 2018. This is not the year of release, but the date of the project's launch!
  • ๐Ÿ”น D1 โ€” In this case, indicates the first revision of the device (D - diagonal, 1 - version).
  • ๐Ÿ”น SG โ€” This is important: the TV was originally designed to meet Asian broadcast standards (e.g., support for Singapore as a target market). DVB-T2 Singapore may be different from European models).

Interestingly, similar models for other regions may have different suffixes, such as the M1805D1IN for India or the M1805D1EU for Europe, which explains why devices with the same "stuffing" may have different supported Wi-Fi frequencies, a set of preinstalled applications or even remote control.

A critical nuance: the SG TV is not officially intended for Russia and CIS countries, which means that when buying through informal channels (for example, AliExpress or local dealers), you may encounter a lack of support for local TV standards or warranty service.
