Free&G-sync

[Dazzler.14]

Is there such thing as a monitor supporting both freesync and g sync 144hz 1080p? 

[Oshino Shinobu]

Nope. 

EDIT: Most likely (still not likely) case of cross-platform support on a single monitor is if both Nvidia and AMD (more so Nvidia) decide to support VESA's Adaptive Sync and abandon their own standards (or at least combine them)

[Moonzy]

not today

probably never will

since gsync monitors will cost more due to the module, so people who wants freesync would just get a cheaper freesync monitor

[Bl00dgod]

gsync is a proprietary standard of nvidia where they put a 200 bucks module on the displays that does that magic

freesync comes from the new displayport standard called adaptive sync

Thanks for clearing that up for me ?.

it would be too expensive to implement and there would also be physical space constrictions as G-Sync module requires a custom built by nVidia interposer as well as pretty much the entire innards of the monitor having to double those will be expensive and hard to fit into a flat screen

 

so don't expect it ever to exist,

your best bet is hoping that nVidia complies to the open standard

It wouldn't be double. It would just be like a normal G-Sync monitor, as FreeSync doesn't require a module and is done through the DP interface (1.2a I think).

Is there any difference in quality of experience in either? With nvidia being more costly?

arguably, not much difference for most cases

Not really. Other than some specific situations, they're about the same. Nvidia is still claiming that the G-Sync module offers many more features, but we're yet to see these features. Many think they're either bluffing, or the features are crap so they're stalling. 

I would be happy if Nvidia supported FreeSync or Adaptive Sync without their proprietary module as a requirement. If the module really does offer some more features in the future, then make it optional. It would be nice if Nvidia played ball with the other kids at some point, rather than building a wall and locking their features down to their own weird, arbitrary requirements.

 

I'm a GSync user myself, I like Nvidia's products but I do get annoyed with their tendency to lock down users and vendors and not playing well with other companies. Especially with technology that would be so good if it were standardised. Even with DX12 supporting using Nvidia and AMD GPUs, you can almost be sure that Nvidia is going to release a driver update at some point that breaks that feature.

yes but nVidia replaces the regular interposer on every display with their own G-Sync module which does not comply to 1.2a and if nVidia has control over it, they will never allow it

True, but I guess this is a hypothetical monitor. If there was a monitor that supported both, then it would most likely just have to have a GSync module with an extra DP interface for FreeSync. 

We won't see a monitor like that, though, I agree. Most likely event is that both companies support VESA's Adaptive Sync standard. The way that Nvidia has locked GSync down does annoy me sometimes.

What does gsync offer over and above Freesync?

 

3D Vision support

Strobing which eliminates blur for fixed fps.

 

Quality varies less with gsync as Nvidia control the quality. Not all Freesync monitors are actually good especially avoid any that have a maximum frequency that is not at least 2.5x that of the minimum as those have very poor behavior around the minimum FPS. Its not a lot for the extra money really but if you use 3D active shutter glasses or like zero motion blur for games like CS:GO then its the best combination option (other monitors have these but none have all 3 modes).

3D Vision is not a feature of G-Sync that's a different nVidia Geforce proprietary feature which has nothing to do with G-Sync

AMD has AMD HD3D for that, it's not that great though but it is as good as nVidias multi-monitor support (:

 

Adaptive-Sync as a standard does not require functioning strobing for blur reduction, but most if not all manufacturers implement some kind of backlight strobing to minimize the blur effect. Not everyone implements if flawlessly but that is the responsibility of the monitor manufacturer. With G-Sync it's nVidia's responsibility.

(I don't know why you said "eliminates blur for fixed fps", because it's not an issue, the issue is with proper math behind functioning blur reduction trough backlight strobing on fluctuating fps for variable refresh rate monitors. Perhaps you mistyped?)

Gsync modules contain 3D vision. I know of one monitor that doesn't which is the Asus PG279Q and its something to do with it being an IPS monitor. The Gsync modules are basically the third revision of the nvision monitors, but of course gsync is a far more capable technology and its been renamed. But the gsync modules have the capabilities of the previous nvision monitors including the low motion blur mode which was unofficial but usable in the previous monitors and 3D vision which I used on my PG278Q.

 

Its not backlight strobing that most manfacturers are using its simply overdrive. Backlight strobing is a different mode where it acts like a normal vsync monitor but it uses a flashed backlight which removes the persistence and takes away the poor periods of pixel transition. Freesync monitors don't have that mode at all. No monitor I know of has the ability to combine adaptive sync and strobing today. What you are talking about is called overdrive and all that does is boost the voltage of the pixel past the target voltage to accelerate how quickly the colour changes, which gsync monitors do very well and some freesync monitors do well as well, but  again read those quality reviews from tftcentral.co.uk because some of them are terrible.

 

You are wrong on all points sir, you just are.
