Avoid
As soon as it was delivered, I had to return it because the cover failed, which seems to be a recurring problem with this model according to the reviews on another site.
Thanks to the guarantee, a new device was sent back to me but after 6 months, the HDMI sockets failed. In the meantime, I'm using my old projector (fortunately it works).
I don't have any way of measuring the latency of the X11-4K, but you can feel it on a game of solitaire, so it's impossible to play a video game with it.
It projects a blurred image when you switch it on, and you have to wait a minute before it stabilises (or play with the focus twice in a row). What's more, it's not capable of projecting sharp images onto both the centre and the edges of the screen.
Finally, I regret that you have to press 3 buttons to change HDMI (my old projector had a shortcut on 1 button).
Its only advantage is its low noise level, but for a device that costs almost 3 times as much as its predecessor, I really regret my purchase.
