Long-time and experienced projector owners, like me, know very well that on a white screen, with room lighting, 3200 lumens is not enough, the contrast will still be shameful.

In complete darkness, more than 500-600 lumens are NOT needed for 3-3.5 sq.m of white matte screen with reflectance = 1.
The on/ioff contrast is much more important, and it is obviously shameful here. ANSI contrast can also be achieved.

The absence of mechanical lens shift worsens the installation - the projector will have to be placed strictly in the center of the screen. In fact, you will have to place it only in front of you, and strictly on the table.

Moreover, the absence of a manual system for reducing brightness to the specified limits in cinema-theater mode in complete darkness sharply deteriorates the quality of the picture due to monstrous reflections at such brightness, and hence its comfortable use.

The noise from the cooling system is obviously monstrous in such a small body with such brightness, as is the rainbow from 1xDLP, which is visible to absolutely everyone in a dynamic picture and especially in black and white scenes.

I don't know who buys them and why - such flawed options. For games, input lag and response time are more important. Playing on 1xDLP is a so-so experience, even with the disgusting picture contrast (below 100:1) with the slightest lighting in the room.

I'm not saying that there is no trace of 4k there - ordinary 1080p matrices with high-frequency shift in an extremely cheap design.

I know many unhappy buyers of such garbage projectors from China for poor people, in which they quickly become disappointed due to the above shortcomings and either move on to buying a serious cinema-theater projector or return to TV (which is more correct for the majority).

Unfortunately, despite the fact that hdmi 1.4b has been around for more than 8 years, today it is impossible to buy a real (in terms of resolution) 4k projector of normal quality cheaply for your home. They are still very expensive and there is a reason for this - they are killing cinema chains in all countries. Their attendance is already plummeting, but 4K projectors will simply finish them off. Although no one cares about cinemas and their owners for a long time.
