The Sony X90J base follows Sony's traditional triangular style and is just the right height to fit some of the regular supporting devices, such as TV boxes, echo walls, etc., without blocking the view.

Sony X90K is parallel to the desktop base, the metal material looks natural with the TV, the overall use of black color and the shape of the design is relatively stable, which will keep the TV stable.

It is also very simple to install, just plug the base into the corresponding interface.

Both TVs have small bezels and a high screen-to-body ratio, and when they are turned on, they play like a piece of art in the center of the living room.

2. Configuration

Sony X90K and X90J both use Sony's XR chip, while the X90K further optimizes the algorithm of the Cognitive Processor XR and further upgrades the speaker structure to make them sound as realistic and three-dimensional as if they were coming from a picture.

The picture quality of the Sony X90J is amazing and combines perfectly with the PS5.

Usually, I play games on the Sony X90J, and my kids watch cartoons on the Dangbei projector. Because of the diffuse reflection principle of the projector, it is less harmful to the eyes compared to a TV.

I recommend the Dangbei Mars Pro because you can get a 250" picture for the price of a 75" TV, (you can project it up to 300", but I don't have a wall that big in my house)

Anyway, if you're looking for a projector for your movie night, I'd recommend the Dangbei Mars Pro, a laser projector with a brightness of 3200 ANSI lumens. I haven't seen a brighter projector in this price range.
