Buying a monitor that supports 4K natively is already pretty pricey. So does anyone want to take a guess at how much this 8K 120Hz monitor from Sharp would cost?
Most people are starting to get to grips with playing things in 4K. But Sharp produced the first 8K TV this time last year, and so it's no surprise at this year's CEATEC (Combined Exhibition of Advanced Technologies) the company showed off a rather fancy 8K monitor.
According to the specifications listed on the convention floor, the prototype (spotted by Japanese site, PC Watch) uses a IGZO IPS panel that's capable of outputting images at 8K (7680x4320) at 120Hz and with high-dynamic range support (HDR) to boot.
It's no wonder the back of the monitor has eight separate DisplayPort cables, then:
15GB/second. That's how much data the monitor would be pushing out just to support an image at that rate and quality. Bloody hell.
By the time 8K displays become more common, something as gargantuan as Sharp's prototype probably won't be necessary. What was shown off at CEATEC is running off the 1.4 specification for DisplayPort, which supports a maximum resolution of 8K at 60Hz with a colour depth of 24 bits per pixel. That standard was only published in March this year, so we're a little while away before DP 1.5 or DP 2.0 becomes available with more bandwidth and support for even higher resolutions and frame rates.
Of course, then you have to deal with the misery of actually displaying something other than still images and wildlife video at that resolution. Hell, a single GTX 1080 struggles to render most games at 60fps consistently unless you turn the detail down. So the world of 8K is still some ways off.
