Hi! I am using chromecast 4.0 4k. Android 9 built into the projector is very weak. What does it mean that you have activated HDMI 2.0? How to do it? Will I then be able to watch uhd quality programs from chromecast? I am also happy with the projector. In a dark room, the picture and colors are great! You intrigued me that with Amazon firestick you can watch Netflix 4k. Please write how you did it... because I can only watch 4k with chromecast.is correct. The image settings are available in the right Settings page. Yes, I am very satisfied with the projector. I don't use the built-in Android 9. I only use the projector via the connected Amazon Firestick 4k Max. The image and sound are therefore the maximum via the projector. I activated HDMI 2.0 in the right settings. Yesterday I watched a 4k nature film via Netflix. The picture quality was amazing! I have sound on the soundbar via bluetooth. 100% lip sync. Projector is on a small shelf on the wall behind the sofa. The distance to the screen is approx. 3.8 meters.
