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

humbug · 25 Mar 2015 at 12:00

What Nvidia are not telling their readers is that Free-Sync also tunes with the panel.

They have picked up on one panel thats isn't working as it should and saying this is because of a distinction between Free-Sync and G-Sync.
Its a nonsense. that distinction as described does not exist.
Its pure marketing.

What we have here is a difference in quality control, had that screen been G-Sync branded it would never have made it to market. thats it.

That doesn't say Freesync is ghosting because of the driver though....

I will explain it:

He is saying that each G-Sync module is tuned to the panel, which seriously helps with Ghosting. He then says "With AMD, the driver is doing most of the work" (which is spot on) but he doesn't say at all that the ghosting is because of the driver.

So he saying FreeSync makes the Display Ghost correct? Then if the Driver doing must the work isn't the driver at Fault here?

Or is it because of the panel itself -- This is the correct answer.

Read above, Gibbo has said the monitor isn't to blame. So what does that leave?

humbug · 25 Mar 2015 at 12:03

The Confusion here is Nvidia making a distinction between G-Sync and Free-Sync that does not exist.

I've just had this response from customer service:

So if it's not the monitor causing it then what is

I got given an RMA number yesterday now get told this.

Ghosting is a on going issue with "all" TN LED displays.. Its always been there in every single LED display you have owned.. Some displays hide it better other not so much.. So therefore its not a fault with the display but more a downside of LED Tech!

I am not going around the houses on this all day. Read it how you want Shanks.

PR hit piece........and its the panel that would cause ghosting; all panels can suffer from it; doesn't matter if its a normal; g-sync; adaptive sync......

some people are more sensitive to ghosting that others;

Exactly this.

G-Sync or Free-Sync this particular display with ghost on both.

Aren't they just LED backlit?

Correct I should said LCD!

Martini1991 · 25 Mar 2015 at 12:16

I never noticed ghosting on my Sammy 120HZ TN, but I did on my IPS 21:9.

As opposed to side lit yes.

The problem is the speed at which the pixel can turn on or off or change colour, if its not fast enough you get motion blurring as the pixel is still illuminated when it should be off for a crisp sharp in motion image.

This is made worse by back-lit displays because they angle the light directly through the pixel.
It makes for a display with deeper contrasts and better colours because the pixel is better illuminated. but if the pixels are a little slow that better illumination of them will result in motion blur.

No I don't think that's what Gibbo is saying at all, otherwise he would have accepted the return and tested it. He seems to be alluding to another cause.

If AMD have certified it then clearly it is working as it should, is it not just the case that there is far less quality control going on with Freesync monitors, or that the bar is set lower? that's the downside to being non-priority as long as monitor manufacturers meet the DP1.3a spec they can claim to be Freesync.

As it should is the wrong word. "Not good enough" perhaps.

Now being told it's a cable or system issue lmao.

I've used 2 different cables so far, both the same, one was shorter than the other as well.

Other people using it with the same card as me and don't have an issue, nor could I see ghosting when using it on my previous monitor.

Nothing like being fobbed off from customer service.

The least they could do is test it.

I thought I was going free-sync but at the moment it's not looking like the best option. Or even as good an option. My 290x hit's 30fps or lower all the time and that's at 1080p, So if I was to buy the 2560 x 1080 21:9 that has a 40 hz cut off point I'm not going to get a great free-sync experience. I understand why people are gonna claim it's not an issue after having just bought into the tech but it clearly is. It was also highlighted on this forum up to a year ago but ignored and ridiculed by the usual suspects. AMD are in a bad place at the moment, I pray they don't go under and leave us at the mercy of Nvidia.

Exactly this, and the same people would have jumped all over gsync if it had ghosting issues on launch.

In fact some of them jumped on it anyway and said gsync wasn't really needed because they couldn't notice tearing :eek:

30FPS what games mate?? Am running Single 290x here @1440p and ripping through games.. Am quite shocked how well the 290x handles 1440p tbh

30fps at 1080p something isn't right there man.

Its not the fixing tearing am shocked about! The tearing has you know meaning nothing to me.. Its how it smooths out the games.. Playing Tomb raider @ 1440p avg around 60fps and then jumping down to 1080p avg around 100fps I couldn't notice the difference.

Everything am playing testing so far I can notice the difference in smoothness..
Plus the added fact you get zero input lag is massive to me.. The tearing I couldn't careless. Added bonus!
