Nvidia Explains Why Their G-Sync Display Tech Is Superior To AMD's FreeSync

It is a solution just like turn off your monitor is a solution.

What if someone wants a bright contrasty screen? They will have to put up ghosting until freesync has driver support to mitigate it, or they can use a gsync monitor.

No then they would have a display showing incorrect information. Just like having your brightness over done loosing out of detail in shadows.

A display with correct calibration is a good display.

Simple has that. You choose to over do settings you choose to loose out on detail.

I've seen three people saying they are returning theirs because of ghosting is that not a loss of sales?

I seen one person on here.. And been told he can not

Freesync isn't causing it, but it also isn't solving it either.
Gsync includes additional processing to combat ghosting, so it is a plus point for gsync. Similarly "Free sync doesn't combat ghosting" could be seen as a negative. What causes the ghosting is largely irrelevant, if a consumer has a choice between having ghosting or not, it is going to affect sales, as we've already seen.

There is nothing that G-sync does to combat Motion blur that Free-Sync does not also do.
Its Nvidia marketing, they are trying to say that Free-Sync does not sync with the monitor, that it works like ordinary software V-Sync, this is where Nvidia talk utter rubbish and they know it.

G-Sync can do nothing about the Screens Pixel refresh rates anymore than anyone or anything can.

Not to mention most us over on the owners thread also point out we don't see the ghosting.
Even before I adjusted my settings I only seen it in csgo on writing on the wall.. Didn't see it in anything else..

I also don't see it in the ufo test.

bake73 · 25 Mar 2015 at 17:51

I have the benq and have seen no ghosting in games or that ufo test.

If you don't see it, you have nothing to worry about

Absolute rubbish.

You talk about intelligence on the last page yet can't even read up on why GSYNC does combat ghosting.

The UFO test is not the one you use for ghosting, they have a proper ghosting test: http://www.testufo.com/#test=ghosting

If you can't see part of the image trailing behind that then your monitor must be very different from mine, as I've even tried using the same settings.

It would be nice if someone else with an iPhone 6 or slow mo camera could upload their results to prove my monitor must be dodgy.

Maybe it's G means GhostSync?

Nah I think that name will be reserved as a nickname for freesync if future monitors keep showing it.

It's funny how I'm the only one alongside the review video on here to show it. Yet everyone saying their screen doesn't have it can't upload the video to prove it.

I did upload a video.. But video also adds extra blur.

Ayahuasca · 25 Mar 2015 at 18:16

I meant a video of the same test.

I can't notice it in CSGO either, doesn't mean it's not there at some level or won't be a nuisance in other/future games.

If it added blur, it must be there in the first place

He didn't think it was right, as there was 2 spaceships instead of one and thought there was summit wrong

No lol you recording footage at 30fps on a camera when the refresh rate is 144hz makes for very bad unwanted effects added to the footage.

If the a driver has to be tunes to each panel i can see this leading to issues are the number ramp up given how Crossfire support is handled. As for the ghosting thing we need to see far more examples.

Well if that is true i can't see it being a huge issue given there are only a handful of actual panel manufacturers.

eh, no. Increasing brightness will increase shadow detail.
It is all a personal choice how people run their screens, lowering the brightness is not fixing the ghosting problem caused by VRR, it is just trying to make it less visible while at the same time greatly changing the way you view the screen.

Ayahuasca · 25 Mar 2015 at 18:34

Shankly don't you have your screen at 100% brightness?

I'm no expert but no screen I've ever seen properly calibrated runs at full brightness.

Is the room you use it in lit by neon lights or something?

Fact one ghosting isn't from VRR do your research man..
Fact two increasing brightness doesn't increase shadow detail at all it washes them out. Making things easier to see isn't making the IQ better..

The lower you can get that brightness while keeping in the RGB range is better.

Yes there are things Nvidia can do to reduce ghosting :rolleyes:

All modern monitors have technologies that reduce ghosting, these technologies don't work with VRR because they don't know when or how the next frame will render -the GSYNC module knows the timings and so can correct for Ghosting. Freesync can't do that currently because they are missing the necessary hardware.

No am now using it around 70% that was before I use test pattern for brightness.. All I changed at that time was contrast.
