Nvidia’s latest drivers for Kepler GPUs now allows the cards to output to 4K TV displays at 4K@60Hz over HDMI 1.4.
Something that wasn’t expected to happen until HDMI 2.0! It’s not magic; it’s just that a compromise has been made, lowering the image quality.
We’ll still need to wait for HDMI 2.0 to see full support for 4K@60Hz. At the time being however, 4K TV manufacturers have decreased the image quality so that there’s less data that needs to be transmitted, allowing it to fit within the 8.16GBps bandwidth limit of HDMI 1.4.
Manufacturers such as Sony and Samsung have employed chroma subsampling, which reduces the amount of colour data being transmitted and frees up bandwidth to bump up the resolution from boring old 1080p to 4K.
Team Digital Samurai is currently on a hands-on review of various 4K TV sets. We’ll keep you posted guys!
