Acer XB270HU - Worlds First IPS, 1440p, 144hz, Gsync

Advanced Hyper-Viewing Angle (AHVA)

Again while not strictly an IPS panel variant, we have left AHVA in this section as it is designed as an "IPS-mode" technology. Introduced first at the end of 2012 this technology is designed by AU Optronics as another alternative to IPS. Confusingly the AHVA name makes it sound like it's a VA-type panel, which AU Optronics have been manufacturing for many years. It should not be confused with AMVA which is their current "true" VA technology produced. To date there has only been one AHVA panel produced, a 27" 2560 x 1440 resolution module which has been used in only one screen. The BenQ BL2710PT featured this new technology and gave us some insight into the performance characteristics of AHVA.

Like a Golf, but not a Golf.
 
I'm mad the AU screen isn't a VA TBH. I was looking forward to replacing my Dell 2405 with a larger high contrast screen, and the Samsung 3440x1440 VA is a little pricey for a second system.

Anyway this AU 2560X1440 AHVA could turn out to be a decent screen and hopefully it's much better than the one fitted to the BenQ.

I think some people are mad because they thought "all monitors will have freesync by default" and then Acer drop the gsync bombshell instead :D

Nvidia sell the same amount of GPUs as AMD sells CPU and GPUs.... anyone with half a brain would put gsync on there monitor then freesync, nobody realised that since theres been hardly/if any freesync monitors
 
Hmm, interesting times we're living in. But before forming any concrete opinions, I would like to hear the prices first, too. Either way, personally I would prefer a 30"-40" 1080p Freesync monitor (or 40" 1440p at most). But then again, I'm in no hurry to upgrade atm, so I will most probably skip this round, in any case. (Yes, I know most people will think 1080p is too blocky, especially at 30"+, but it's good enough for me, so let's not go into that any further)

Also, did they just skip IPS 60Hz G-sync? I don't see why they wouldn't take benefit of a very lucrative iteration round. Is Freesync coming too fast, or is there something entirely new in the pipeline, causing them to skip a natural market evolution phase? Isn't this also the first mainstream (non-Korean) 144Hz IPS monitor...? Actually, now that I think about it, they are basically skipping all these iterations:
IPS 1080p 144Hz
IPS 1440p 144Hz
G-sync IPS 1080p
G-sync IPS 1080p 144Hz
G-sync IPS 1440p

From a seller's perspective, it doesn't make sense. Good news for consumers, though. Then again, also good news for GPU manufacturers, especially nVidia, in this case. Then again, because CES is so close and Freesync is around the corner, I feel this would have been more effective like three months ago. Between now and March, there will surely be more updates to the Freesync bandwagon. I don't think people are so impatient that they would upgrade their GPUs in advance, just before CES, of all things. Interesting times, indeed.

@jigger:
There are three main types of LCD monitor panels: TN, VA, IPS. They have sub-classes, like PVA, SPVA, AMVA, AH-IPS, eIPS, PLS, etc. How would YOU categorize AHVA? Or are you claiming that it's a completely new (fourth) main type? From what I've understood, the industry seems to categorize AHVA under the IPS-moniker. Why should we categorize it as something else?

@TheGentry:
If Technology A has a X % percent market share and Y € licensing fees and achievable market price of Z €, while Technology B has 0.5X % market share but only 0.2Y € licensing fees and achievable market price of 0.7Z €, would it be stupid or smart to use the Technology B?

Furthermore, there is only a handful of G-sync monitors we know of, and even less Freesync monitors. Also bear in mind, the Freesync (/Adaptive sync) is an open industry standard. That gives it a head-start. But indeed, how about we first wait for the actual monitors and their prices (and other data, as well) before we compare them head-to-head? Also, the upcoming CES will hopefully enlighten the situation a little further. Acer just took an early start, hoping to build up hype. Let's wait and see what others have to offer.
(But if there are no Freesync news at the CES, I'll feel quite disappointed -- although personally I'm mainly waiting for NUC news)

I would guess the reason is because G-sync is really aimed at highend gamers and a highend gamer is not going be interested in buying a 60hz monitor..;)

4K is different due to there no 120hz or 144hz 4k panels available yet and I don't think DP 1.2 even has enough bandwidth to run a 4k screen at 120hz or 144hz

I thought G-Sync was just meant to make games a helluva lots smoother at lower refresh rates and have a lesser effect at higher ones.

Regardless I'll stick to 100Hz 1440p IPS. I have enough trouble affording to drive games on this let alone 144hz.

What do you mean by 'the BenQ'. Which BenQ? BenQ are the parent company of AUO. AUO manufactures the panel for most current 144Hz models on the market (including the ROG SWIFT, BenQ XL Series, various AOC and ASUS models etc.) They are all Twisted Nematic, which is completely different. We can hope that this AHVA panel behaves much like a higher refresh rate version of their 60Hz AHVA panels, hopefully with slightly tighter response times too.

There is a reason these panels are referred to as 'IPS-type' (as are Samsung PLS panels) and as 'IPS technology'. They are for all intents and purposes the same thing. The key characteristics are identical and internally they are extremely similar. It can't be called 'IPS' because that is a trademark of LG Display, but that doesn't matter one jot to the consumer.

I have no regrets on buying the ROG, it remains to be seen how the response time actually is, it might be better than a 60hz IPS but I doubt it will be up to Swift standards... even if it matches it I have no issues with the colour handling on the Swift and I'll have had the benefit of that for over 6 months by the time this monitor comes out - I think we all knew we were paying "early adopter" prices.

Gsync works at all refresh rates. As with vsync it eliminates tearing, but vsync can only work in big jumps of refresh rate, full then half and so on... gsync works in 1fps increments so when you get a small dip in FPS you only get a small dip in refresh/frametime instead of the big jumps that vsync brings

with vsync, if you miss the 16.6ms frametime limit at 60hz you get a big drop to 32ms... with 144hz if you miss the 7ms limit it drops to 14ms which is 72hz, so that is still a huge difference and very visible if it keeps happening

with 144hz monitor is it very unlikely you'll be able to hold 144hz solid, so gsync is arguably a bigger benefit at 144hz as it means you get every frame delivered as soon as it can, instead of the buffering and handling that goes on with a variable frame rate with vsync on

vsync also suffers from input lag which gsync is able to basically remove
