Dang, really looking forward to a good monitor with this. Anyone want a 120hz Alienware monitor?

It was good that we were also unable to detect any input lag degradation by using G-SYNC instead of VSYNC OFF. There were many situations where G-SYNC’s incredible ability to smooth the low 45fps frame rate, actually felt better than stuttery 75fps — this is a case where G-SYNC’s currently high price tag is justifiable, as Crysis 3 benefitted immensely from Crysis 3.

Glad to see below 60FPS tested.

It looks like they are simply trying to convey that G Sync adds almost nothing input lag wise over running with V Sync off, however, it gives the real improvements in tearing and stuttering.

Yeah basically g-sync is like triple buffer vsync but without the input lag, is my take on it. Too bad it requires new monitors. I have triple-monitors and there is no way I'm paying the G-sync tax three times unless the tax is pretty low. I'm not paying three times the early adopter tax, either.

I don't know if this is the right place for this question, but with 4K at something like 28" if you ran the monitor at 1080p while gaming wouldn't it just be like have a 1080p monitor? Are the pixels small enough that several would just combine to have the same density as a regular 1080p monitor?

Would be nice to have the screen real estate in desktop and the performance in gaming until GPU's catch up.

Just as I suspected, nothing but troll posts and name calling lol.

What I did glean is that 1080p on a 4k monitor should look similar to 1080p on a similar sized 1080p monitor.

4 4K pixels should be the exact same size as 1 1080p pixel on the same sized monitor. That seems like a great reason to hold off for 4K. More real estate in desktop and 1080p in games.

One reason not to get 4k however is that the desktop scaling in Windows is still pretty bad, even with Windows 8.1. The applications don't support it well yet and it can really ruin your day if you use an app that doesn't scale properly. I don't think anyone would want to be switching back and forth from 1080p and 4k resolutions in different desktop apps.

As to whether its like triple buffering without the lag its actually a lot better than that. Triple buffering ensures the frame rate is maintained (no 30/60 issue) but it doesn't ensure the frames are delivered at the right moment. So while you get more fps with triple buffering it does not eliminate the vsync stutter, and most games these days use DX's version of triple buffering (3 back buffers anyway) to eliminate the lock to 30 fps, but you can still only display an image every 16.6ms and you can't ever display between those points. Triple buffering does not eliminate the stutter, it solves a different problem (which gsync also solves).

I think I am going 1440p so long as that Asus monitor isn't terrible. I'll wait for 4k to become more popular, a year or two at least and then maybe the landscape will change and we'll have vblank variable refresh rate generically and better 4k support in Windows.

You really need to do cross posting reading. It's hilarious:
In the Mantle thread you have the people telling us how great it is to play with 120FPS on a 1080p TN monitor.

In this thread the same people told us how awfull 120Hz TN monitors are and they would only buy a G-Sync monitor if it a >2560x1444 IPS display.

Oh and paying $200 more is a show stopper but another $500 AMD card is no problem.

4k G-Sync is something that I would love to experience, but my guess is the price wont be where I want until Xmas.

Price, availability and the future of the technology remain the main concerns. When Nvidia released the news I was skeptical about how they would handle AMD, Intel and licencing concerns for the technology. The answer I think is "very badly". So badly infact that AMD is creating its own implementation that is sort of similar but quite different from scratch. Rather than trying to work out a standard from the work done at Nvidia on this they are completely ignoring it and moving on with their own somewhat different approach.

This remains a grave concern, I don't want to buy a gsync monitor to use it for a year (especially at the prices being talked about) to find out that in a years time that DP 1.3 contains it by default and many monitors have it and Nvidia abandons it completely or worse continues having a competing and incompatible technology. This sort of behaviour is bad for all of us.

I promise you that AMD is not pursuing a new technology and its implementation, without a plan on how to recoup their investment and more. They just don't have the capital to throw around for charity.

The reviews G-sync has received are overwhelmingly positive. Early adopters are paying a tax, as usual. But it isn't going anywhere anytime soon. The price, as well as the mass market's understanding of what it actually is, are the current barriers to entry. It really doesn't have a catchy tagline, like "Ultra HD!" for 4k.

This sort of behavior is great, imo. For some reason proprietary investment has received bad press. The reason it is great is because it causes reaction from competition.

As such, there is nothing wrong with two separate competing products in the same field. The weak one will die off or be relegated to obscurity, leaving the strong to be adopted on a wider scale. Yes, those who chose the loser are out some coin, but that's life. Without a company and customers taking a risk, we would stagnate.

I need a new monitor soon but with all these new technology coming in '14 it's getting hard to choose. Probably gonna be easier to make a decision once we see the prices lol.

They are on the market...it is a matter of volume driving down the prices hopefully. 4k seems to be dropping semi-quickly, although it isn't exactly ready for mass (price) appeal yet.

It looks like 4K is the next standard for consumer TVs- Vizio are bringing out a $999 4K TV this year. Lots of 4K TVs means cheaper 4K panels. I wouldn't be surprised if a 4K monitor was cheaper than a 1440p monitor by the end of 2015, same way a 1920x1080 one is cheaper than a 1600x1200 one right now.

Of course a larger resolution will mean larger buffers needed in the G-Sync module, so the premium will go up a bit; but hopefully not too much.

The availability of 4k this year really does have me questioning whether early adopting 1440p gsync is a good idea. Those people who have 4k monitors already are reporting very poor performance on upscaling 1080p to 4k despite the obvious that would produce sharp and presumably 1080p like images. That makes me pause because one of the big benefits of 4k has to be that you can run 1080p on it as well without concern.

Really don't know what to do at this stage, no doubt I want gsync as soon as is reasonable, and I have justified waiting for some options for a few months especially to see the 1440p monitor but I am wary about buying now because 4k is coming on quite quickly now. I still suspect it will be a few years before they are $200 however, and that is the true mass market adoption price.

4k needs content to push it to TV consumers, but I agree with you as far as the path that it is on. The budget for Johnny Walmart's TV purchase is generally higher than a computer monitor. Those budgets generally remain static, so what we see with the majority of the market today (1080p) is the same range that 4k monitors would have to reach to enjoy the same adoption rate.

And they will...but end of 2015 like you mention is probably closer to reality.

I don't know but with a 4k 60 hz TV's won't that be display port only , leaving any add on hardware with a hdmi to be a connection/bandwidth issue -dvd , avr's , dvr's ,cable boxes , would be out of date.

If they use HDMI 2.0, it will support 60hz, but capable of backward compatibility with current HDMI versions to use with old tech, like DVR's. So as a TV, it'll likely use 30hz, or take 30hz of input and convert it. On a PC, you use an HDMI 2.0 cable (or just a normal high speed cable), and get 60hz.

Unless you are specifically thinking of G-sync. In which case they may have to have both displayport and HDMI connections. I don't know if that is a problem or not. The DYI kit is displayport only, but that may not be required on future products.

This is how just about everything works. Remember HD-DVD? It was a competing technology with Blu-Ray, and they coexisted for a while. Eventually, Blu-Ray got to the point where it had enough market share that HD-DVD ended up getting shelved.

It would be great for us if companies would just give away their intellectual property to their competitors, but how can we really expect them to?
