So, with 14-bit video, the TV now has 16,384 for the processing algorithms to work with.

Notice how with each additional 2 bits, the number of available video levels increases 4X. Today’s HDR video is 10-bit, with 1024 luminance levels. Video like what you watch on cable TV or an HD Blu-ray, SDR video is “only” 8-bit, which means luminance is expressed in 256 steps. All this needs to be done at incredible speed and resolution: Up to 120 times per second in 4K (2160 x 3840 pixels).įirst, a bit of background.

Furthermore, the processor has to control the backlight array and synchronize it with the quantum dot panel to create the final image. The required processing varies: Depending on the source, it can involve deinterlacing, upscaling, noise reduction, banding reduction, motion interpolation, local contrast enhancement, sharpening, tone mapping, and color adjustments. TV makers like to tout the improvements achieved through advanced video processing, which translates a raw video signal into the best image the TV can create. The new QN90B takes the same hardware as its older sibling and ups the performance by upgrading the video processing from 12-bit to 14-bit. Last year I reviewed the QN90A and found it to offer the best combination of performance, value, and size among premium 4K TVs.

Thanks to the adoption of 14-bit processing, it achieves a higher level of picture quality than its predecessor and delivers on the picture quality potential of Neo QLED display technology. It is a tremendous performer among 4K TVs and a model that builds upon the strengths of the already-amazing QN90A. The Neo QLED QN90B from Samsung is the company’s flagship 4K model for 2022.
