The latest and greatest thing in TVs are new models with 8K resolution. That’s 7680x4320 pixels or four times as many pixels as a 4K TV and 16 times as many as a 1080p TV. Do these new 8K TVs offer a differentiated experience? Can you see the difference?
What’s most fascinating is that rather than pointing out the increased sharpness or contrast of the image associated with higher resolution, participants highlighted the main differences to be those related to sensory perceptions – i.e. objects look cooler, warmer, more delicious, heavier.
The researchers concluded that this hyperrealism effect connects the perceptual aspects on the image (contrast, color expression and resolution) with the cognitive aspects perceived by the brain (weight, temperature, reality, space, depth and high image quality). That’s very interesting that the increased resolution has a stronger emotional impact.
A separate study by Dr. Kyoung-Min Lee of Seoul National University looked at the effects of super-resolution (8K) displays from the point of view of the brain. His main conclusions were:
- Super-resolution reduces information loss thus creating a more realistic image
- Super-resolution displays increase the dynamic signal-to-noise ratio reducing cognitive loading and increasing the immersive effect
Having more pixels reduces jaggies in lines and moire effects leading to naturally sharper edges. These sharper edges make it easier to see separate objects allowing for an increased sense of depth. This effect is evident on native 8K content and on upscale/restored content as well.
