Affordable home cinema with Xiaomi. This Google TV projector on Alza has never been cheaper, it also handles autofocus

A smart projector with built-in Google TV and autofocus is a convenient way to set up a home cinema without complicated tuning. The Xiaomi Smart Projector L1 Pro now costs 6,112 CZK instead of 7,190 CZK with code ALZADNY15. It hasn’t been cheaper on Alza yet, and given its price, it offers solid features.

Quick summary:
✅ Makes sense if you want an affordable smart projector for a home cinema in a darkened room with convenient automatic image adjustment.
⚠️ Consider that the brightness of 400 ISO lumens is low, so the image won’t stand out in daylight.
💡 For 6,112 CZK, you get Full HD, Google TV, and autofocus, but it’s an entry-level class, not a powerful projector for a bright room.

Why this projector is interesting

The main advantage of the Xiaomi projector is that it functions as a complete smart device, not just a projector. It has built-in Google TV with voice assistant, so you have streaming apps and content directly on the projector without connecting an external box. In addition, an image with a diagonal from 40″ to 120″ turns a white wall into a large home cinema.

In terms of price, the model makes more sense now than ever. At 6,112 CZK with code ALZADNY15, it’s the lowest price it has been sold for on Alza so far, and Alza itself describes the discount from 7,190 CZK as real. Over 500 units have been sold, and it holds a rating of 4.5 out of 5 from 21 reviews.

Key parameters explained in plain language

The projector projects in native resolution 1920 × 1080 (Full HD) and also accepts a 4K signal, which it converts to its native resolution. The native resolution is the important number because it determines the real sharpness, while the accepted 4K merely indicates what signal the device can handle. Smooth operation is handled by the MT9630 chip with 2 GB RAM and 16 GB storage, and sound is provided by two 5W speakers with Dolby Audio.

The most important number, however, is brightness: 400 ISO lumens (certified according to ISO standard). This is a value for darkened spaces, not for a room full of daylight. The contrast of 1,500:1 is rather basic for a projector. As a short-throw projection with a ratio of 1.21:1, it can handle a large image even from a relatively short distance (1.2 to 3.6 m), making it suitable for smaller rooms.

Practical aspects: setup, installation, ports

This is where the projector earns points. It offers autofocus, omnidirectional keystone correction (±15°), and automatic obstacle avoidance on the wall, such as light switches or picture frames. In practice, this means you can align the image virtually without manual tuning, which is certainly not a given for cheaper projectors. You can install it on a table, on the ceiling, or for side projection.

Operation is quiet; the manufacturer states noise levels up to 30 dB in Cinema mode and a sealed optical unit against dust. It connects wirelessly via Wi-Fi 5 and Bluetooth 5.0 and supports mirroring via Google Cast. However, note that there is only one HDMI port, a USB 2.0, and a headphone output, so it’s not suitable for connecting multiple wired sources simultaneously.

What to watch out for

The most important point is brightness. With a brightness of 400 ISO lumens, this is a projector for darkness — during the day or in a brightly lit room, the image will be faded and hard to read. If you don’t have the option to darken the room (curtains, blinds), consider it twice, as a lack of brightness is often the biggest disappointment with inexpensive projectors.

The second thing is that it’s an entry-level class with a basic contrast of 1,500:1 and a single HDMI port. For occasional movie nights and series in the dark, it’s more than enough, but don’t expect the quality of expensive home projectors or use it as a TV replacement for a living room where the sun shines. It’s a device for a specific scenario, not a universal one for all conditions.

When it doesn’t make sense

If you want a projector for a bright room or for daytime viewing, 400 ISO lumens will disappoint you, and a TV or a more powerful (and expensive) projector would serve better. Similarly, if you need to connect multiple wired sources (console, player, PC simultaneously), the single HDMI is limiting. And whoever is looking for top-notch image quality for a demanding home cinema should aim for a higher class, just be prepared for a significantly higher price.

Verdict: who the discount is worth it for

The Xiaomi Smart Projector L1 Pro is a reasonable entry into the world of smart projectors, mainly thanks to its built-in Google TV and convenient automatic image adjustment. At 6,112 CZK with code ALZADNY15, it’s the lowest price it has been sold for on Alza so far. Whoever has the option to darken the room and wants a large screen for movies and series without complicated tuning will get a good piece for 6,112 CZK. Whoever needs brightness for a lit room or top-notch image should opt for a more powerful model and expect a higher price.

Do you have the option to properly darken your room at home, or are you looking for a projector that can handle daylight?
