Will 4k monitors be capable of 144hz in the near future?

I'm torn between buying a 4k monitor or a 144hz 1440p monitor.

So as the title says... will 4k monitors be capable of 144hz in the near future?

Or is it a question of the other components such as cables, DVI/DP/HDMI bandwidth capacities etc. that is standing in the way of this?

It's the DP bandwidth that limits it, so not expecting anything soon. If you recall, 4K @ 60 Hz was a struggle when it first came out. HDMI was totally out of the question, and many panels were split in two, requiring two separate cables.

4K G-Sync/FreeSync is the next development (it's already happened, but it will be expanding). 144 Hz will be a while yet.

Thanks. In that case, do you have any opinion over the Asus PG278Q ROG Swift vs the Acer XB270HUbprz, please?

I used to work for ASUS so as much as I aim to be impartial I'm probably not...

The main difference between those two is that the Swift is TN and the Acer is IPS.

That means the Swift will have worse viewing angles and colours, though my experience of modern high-quality TN panels is that they're more than good enough for day-to-day use (though not photography), but it will react much faster than the Acer. TN is the more gamer-esque choice.

The other thing to bear in mind is that the Swift has been around a while, and though it had some teething problems when it came out AFAIK they're pretty good now for reliability. The Acer is much newer, and from initial glance at the OcUK forums the first batch didn't get a good reputation - complaints about build quality and IPS glow / backlight bleed.

Obviously though, YMMV

I had a Swift for a week and sent it back, I wasn't impressed at all. The thing that I didn't like the most was the pixel inversion lines which appear in the ghosting of moving objects and in 3D vision. It also had a dead pixel and the gamma seemed off, with no way to adjust it on the OSD (was around 1.8, not 2.2 where it should be). Mine was a Jan 2015 batch, which is apparently one of the "improved" ones. I don't think Asus is even bothering with quality control these days...

The Acer IPS has a ton of issues as well and is prone to really bad backlight bleed (though the image quality is much better than the Swift). I'd avoid both of them and wait until alternatives get released TBH. Neither are worth the price tag.

DP should go up to 32.4 Gbps

HDMI 2.0 is 18Gbps

Some quick calculations tell me that 4K@120Hz requires ~ 23.7Gbps and 4K@144Hz requires 28.4Gbps......both attainable with DP but not HDMI 2.0.

Interestingly, that means no 120Hz+ 4K 3D content.
