Asus Prototype - The First 4K 144Hz Monitor with DP 1.3

At this year's Computex event Asus has showcased an exciting new prototype screen. There's very little information available yet or course as it's only in the prototype stage, but the screen is based on a 4K 27" panel and supports refresh rates up to 144Hz. We expect by "4k" they mean Ultra HD 3840 x 2160 resolution here by the way (now confirmed). This would be the first official sighting of a 4K screen with a high refresh rate and is also the first we've seen based on the DisplayPort 1.3 standard. This new DP interface allows for increased bandwidth throughput, allowing 4K @ 144Hz to finally become a possibility. DP 1.2 has insufficient bandwidth to support this and so we've been waiting for DP 1.3 to be adopted by graphics card and monitor manufacturers to overcome this.

The prototype is based on a TN Film IPS-type technology panel (AU Optronics AHVA), but remember this is a very early proof of concept. Asus will be limited by the panels available as well don't forget and so the choice of available panels and technologies will improve over time as 4K @ 144Hz becomes possible. No word on any other features like FreeSync or G-sync at this stage and we suspect this was more a case of trying to show 4K @144Hz with DP 1.3 was possible.

More info as we get it.

Update 1/6/16 - this video from the Computex event confirms that this prototype is actually IPS technology (AHVA from AU Optronics) instead of being TN Film, so that's exciting news. It also confirms our the suspicion that the resolution is 3840 x 2160 Ultra HD and confirms that the refresh rate is indeed 144Hz. The spec sheet also says it will offer tilt, swivel, pivot, and height adjustments from the stand.

Update 7/6/16: Linked to this, AU Optronics has announced at the same time that their Ultra HD 4k AHVA (IPS-type) panel is being shown off at Computex, meaning that it must be their panel being used in the Asus prototype.
