The UltraHD 4K era is coming pretty quickly and the limitations of current technology is being rapidly circumvented. Already we have panels capable of displaying 4K content at 60Hz through the use of Displayport Multi-Stream Transport (MST) and HDMI 2.0 and Displayport 1.3 are both being ratified and launching late this year – both support 4K resolutions at various refresh rates and both will allow for a new, fresh assortment of monitors and portable displays that will help dig us out of the 1080p hole.
While these monitors are still pretty expensive, prices are dropping every day. Case in point, observe Samsung’s latest creation – the U28D590D – a 28-inch diagonal UltraHD 4K monitor that will retail for less than US $700.
The U28D590D is one of the cheaper 4K monitors on the market and is priced to combat Dell’s own 4K monitors as well as Seiki, an American-based TV brand that was the first to offer cheap 4K monitors to consumers on that end of the world. Samsung’s solution for 60Hz is the same as most others – because of its reliance on Displayport 1.2, the U28D590D uses Displayport MST to divide the monitor into two logical parts and use AMD Eyefinity or Nvidia Surround technology to stitch them back together into a single, addressable group.
The U28D590D has a reported response time of 1ms grey-to-grey, a contrast ratio of 1000:1 and a maximum brightness of 370cd/m². It supports a number of Samsung technologies like Eco Saving, MagicAngle and Picture-in-Picture 2.0 and is certified for compatibility with Windows 8.1 and Apple OS X operating systems.
It only has two HDMI 1.4a ports and one Displayport 1.2 connector, so there’s only space for one computer for the full-blown 4K 60Hz display mode. HDMI is also technically capable of displaying media at 4K, but only at 30Hz refresh rates. If you’re only playing back movies then that’s perfectly acceptable but for general desktop usage as well as gaming, it’s not that great.
The only issue here is that with the TN panel, colour shifting will be evident at slightly wider angles. If you’re thinking of using more than one in a multi-display group, you’ll definitely see colour shifting and much more muted colours than what IPS, PLS or PVA panels can offer. Still, for the same price as the Ultra-wide 21:9 monitors that you’d typically find on the market, you could nab one of Samsung’s babies for full-blown 4K goodness right now.
There’s also the option of waiting. HDMI 2.0 and Displayport 1.3 are both being ratified this year and in 2015 we’ll see even cheaper 4K monitors that run at 60Hz and even 120Hz that don’t need this kind of trickery to work properly.
