The Sony X900H Bravia is a great TV for almost every purpose. The VAVertical Alignment, type of LCD Panel panel has deep and even blacks with a good contrast ratio of 4800:1. As a result, it shows an excellent picture quality in dark rooms, which the IPSIn-Plane Switching, type of LCD Panel panel of the NANO90 cannot even come close to. On the other hand, the X900H has a very narrow viewing angle at which the colors look washed out even at a slighty oblique viewing angle. Because the Sony TV can become brighter than its competitor, its picture quality is similarly good in bright rooms, but the higher peak brightness makes HDRHigh Dynamic Range – image/video with more dynamic range (contrast range) content look better.
Both TVs have a lot of features, so it is not surprising that, in addition to Dolby VisionDynamic HDR-format with a color depth of up to 12 Bits and Mastering of up to 10,000 Nits and Dolby AtmosObject-based surround sound format with 3D-Sound from any direction, they also come with a well-developed smart operating system.
