Not all 4K UHD TVs
are the same!

Not all 4K UHD TVs provide the same colour and detail,
so how can you be sure of getting the Ultra HD performance you expect?

What makes an RGB TV 4K?

RGB pixels vs RGBW pixels

The difference between an RGB and RGBW UHD TV lies in how the colours are made. Samsung 4K UHD TVs use only RGB pixels, meaning they create images using separate red, green and blue (the RGB!) colour elements. Why? Because that’s the way our eyes work. The cells in our eyes detect those red and green and blue colours, and the full richness of all colours can only be achieved with pure mixtures of those basic elements.

Other 4K UHD TV models that use RGBW add a white element to the usual red, green and blue colour combination. This can make the image appear brighter, but can also decrease colour accuracy, colour range and resolution. How?
