1080P is better. 1080P refers to the clarity of the picture, which is an important indicator of the image, and HDR is an optimization process for the image, which can make the picture more realistic on the basis of ensuring the clarity of the image.
1080P refers to the resolution specification of the projector screen. The projectors with higher configuration and price are all 1080P resolution. In general, if it is a 1080P resolution projector, adding HDR technology will make the picture better.
Full HD is the screen resolution of 1920 x 1080 Pixels, written as 1080P. HDR (Stands for High Dynamic Range) is an imaging technique and has nothing to do with the resolution. In short, HDR means better contrast, greater brightness levels and a wider color range.
