Acer's upcoming ultra-widescreen 34-inch G-SYNC gaming monitor, the XR341CKA, will have multiple inputs according to a report published by TFT Central, which indicates possible changes to the G-SYNC V2 module as previous displays only provided one input.

The Acer XR341CKA is a variant of the XR341CK, a FreeSync monitor that contains an identical panel. The IPS panel in both monitors is rated up to 75Hz refresh with a resolution of 3440x1440, and a contrast ratio of 1000:1 with 8-bit + FRC (effective 10-bit) color depth. The big story here is of course the G-SYNC module, and though we don't know the specific implementation yet is will be interesting to see what the input support of version 2 G-SYNC displays will be. According to TFT Central the FreeSync (CK) variant of the XR341 offers "HDMI 2.0 (MHL), DisplayPort, Mini DP and DP out connections," and "it will support daisy chaining via the DP out port and also PiP and PbP functions".

In contrast the G-SYNC variant (CKA) of the XR341 offers "DisplayPort, but also an additional HDMI 1.4 video connection...(and) will also support ULMB (Ultra Low Motion Blur)." TFT Central points out that this detail "would mark the first G-sync screen we've seen with more than one connection, so we will be interested to see how this works." If indeed this is a single module solution it is possible that NVIDIA has made changes with the second-gen G-SYNC module to allow for more than one input. We will have to wait and see, unless more details about this V2 module are forthcoming.

MIght have to sell my ROG swift for this bad boy. Id rather have 2560 @144hz. if they have this variant Im in!

This should look a lot better than the swift, as the swift is only a TN panel

I really need to change my monitor, since it has really high latency, and it's giving me headache. But now seems to be a really bad time to purchase a new one, considering how fast everything is evolving. I really want a G-Sync IPS monitor like the Acer XB270HU but I'm seeing it has a lot of light bleeding, and that is making me doubt.

Looking good, Tom Petersen at Nvidia definitely left the door open for future G-Sync iterations being able to support multiple inputs, it just required additional hardware and either a 2nd scaler for the other inputs or additional functionality supported by the G-Sync module.

Either way, it looks like monitor mfgs are going to support both formats (G-Sync and FreeSync) which of course makes the most sense given the limitations of both and their tie-ins to GPU mfgs.

There is no freesync, it's called DisplayPort Adaptive Sync, and it's part of the VESA DisplayPort 1.2a standard. All future DP standards will include DP 1.2a Adaptive Sync under VESA(Video Electronics Standards Association). AMD does not have any proprietary standard for synchronization. So your proprietary tie-in assumption in incorrect in AMD's respect. Once AMD got VESA to accept the technological/IP basis for Adaptive sync, and VESA adopted it, it became a VESA industry standard.

Too many people are relying on marketing for their information, and the goal of the marketing profession is to mislead, and outright lie. Forget about companies' trade names for technologies and instead look for the generic names for the technology. Once a technology is accepted by an industry standards organization in becomes an open standard with a manufactures able to adopt the technology, for little or no costs.

VESA is an industry standards organization for display technology, PCI-SIG is the standards organization for the PCI/PCIe related standards. USB Implementers Forum(USB-IF) is another standards organization. ETC!

Uh, you may want to check again, there clearly is FreeSync it is AMD's trademarked and proprietary implementation of DP AdaptiveSync, which is an OPTIONAL part of the Display Port standard and will never be mandatory as long as it carries a premium, which it clearly does.

We are not going to see $100 Adaptive Sync panels from Dell anytime soon, to say the least.

Clearly there are more roadblocks in place than just marketing, as AMD is running their own proprietary logo program with FreeSync, as we recently saw with the Asus panel that was certified FreeSync compatible.

So yes, clearly not an open standard, it is an open spec that allows for various proprietary implementations, like AMD's FreeSync. In that respect it really is no different than Nvidia's proprietary G-Sync which is a proprietary implementation throughout, but needless to say, even if Nvidia were to implement their own version of Adaptive Sync, they would not be able to copy AMD's implementation of FreeSync (TM).

You're grasping at straws, we are not talking about what AMD's marketing chooses to call it. VESA is an open standards organization, AMD, Nvidia, and many other companies have representation on VESA's various working groups. FreeSync is just a trademarked marketing term, the VESA DP 1.2a Adaptive Sync, and other standards are always optional, VESA is the display industry's Standards group, it is made up of all the industry players in the display industry, all of its standards are optional.

Display Port 1.2a is as optional as are all of the other DP standards, full adoption of the VESA open standards is up to the individual display manufacturer, and it is always going to depend on the display manufactures to adopt a VESA standard. VESA membership is voluntary, however if the graphics adaptor manufactures/others begin to make adaptors(GPU, DVD players, etc.) that need certain DP standards and the customers want that capability, you can be damn sure the VESA whatever standard will be included by the display manufactures.

Nvidia is welcome to continue its G-sync line of product, while at the same time supporting, or not, any of the VESA standards, as long as it does not cost Nvidia sales they have that option. The customers will choose the Monitors/displays to go along with their systems, and if the customers choose monitors with both adaptive sync technologies they will have to pay the costs. For sure most display manufactures will probably include DP 1.2a Adaptive Sync, compatibility even in their G-sync enabled kit, if just to insure a larger customer base for that product. Nvidia can not force the display manufactures to not adopt a VESA standard.

The Display manufacturer will include whatever standards that the manufacturer thinks will get it the most sales across the entire market, so expect some displays to offer both G-sync and DP 1.2a, and many display manufactures will probably include the VESA DP 1.2a as the default, and the G-sync as the optional extra. DP 1.2a Adaptive Sync is very low cost for the display makers to include in every unit, even the ones that may offer the G-Sync more expensive solution. Look on the back of most displays there are loads of ports/plugs from many different standards organizations.

Display port Adaptive sync 1.2a is the standard that the display manufactures will use, and AMD can call it FreeSync, macaroni, or whatever!

Read this VESA announcement, do you see FreeSync anywhere on this page?

No, I think you are the one grasping at straws because this launch announcement basically flies in the face of everything you have said:

1) There is a FreeSync version of this monitor
2) There is a G-Sync version of this monitor

Neither of these monitors support both, there are most likely legal and/or technical reasons preventing this but the fact remains both are based on proprietary implementations by each vendor.

There is certainly no guarantee that if Nvidia did decide to implement their own version of Adaptive Sync, that it would work with AMD FreeSync branded displays.

"if Nvidia were to implement their own version of Adaptive Sync, they would not be able to copy AMD's implementation of FreeSync(TM)"

Nvidia is a member of VESA, Nvidia is welcome to use DP Adaptive sync.

"Implementation of DisplayPort Adaptive-Sync is offered to VESA members without any license fee." (1)

It all came from:

"Adaptive-Sync is a proven and widely adopted technology. The technology has been a standard component of VESA’s embedded DisplayPort (eDP™) specification since its initial rollout in 2009. As a result, Adaptive-Sync technology is already incorporated into many of the building block components for displays that rely on eDP for internal video signaling. Newly introduced to the DisplayPort 1.2a specification for external displays, this technology is now formally known as DisplayPort Adaptive-Sync."(1)

That's where AMD got its "FreeSync" from.

P.S. “DisplayPort Adaptive-Sync enables a new approach in display refresh technology, ” said Syed Athar Hussain, Display Domain Architect, AMD and VESA Board Vice Chairman. “Instead of updating a monitor at a constant rate, Adaptive-Sync enables technologies that match the display update rate to the user’s content, enabling power efficient transport over the display link and a fluid, low-latency visual experience.”(1)

But that doesn't change the fact Nvidia is not Free to use the trademarked and proprietary AMD version of Adaptive Sync, FreeSync.

April 18, 2015 | 05:11 PM - Posted by Anonymous (not verified)

It's free(relatively) to use the VESA DP Adaptive Sync, and Nvidia can not stop the display manufactures from adopting any of the DP standards, regardless of any extra added expense of Nvidia's G-Sync, do not expect the display industry to not include the most cost efficient solutions, while charging extra for the Nvidia overpriced G-Sync schemes. The DP 1.2a standard will be in all the third party displays, so the users will have the choice of what GPU to use with the display, do not expect the display manufactures to loose sales for Nvidia's sake. AMD can call it what they want, but that's only marketing to the misinformed who think technology companies are football teams, but that's not the way technological standards work. The most affordable solution will win out in the end, as far as the inclusion in displays is concerned, so expect the DP 1.2a Adaptive Sync standard to see the widest adoption, and DP 1.2a Adaptive Sync will work with AMD GPUs. You just keep that one cell of gray matter busy with your harebrained attempts at splitting hairs.

DisplayPort Adaptive Sync is currently inferior to GSYNC at low frame rates. So the higher the resolution of the monitor the more issues you are going to have.

That's not marketing speak that's people taking the time to measure both of them.

And you are wrong there is Freesync, its a AMD brand. That's why some monitors support DisplayPort Adaptive Sync but aren't branded as Freesync.

Scott Wasson from the tech report view differs.

Unlike Ryan and Allyn who jumped to conclusions he has tested both and has talked to both AMD and Nvidia techs on the differences.

April 17, 2015 | 09:23 AM - Posted by Anonymous (not verified)

Except Ryan and Allyn took the time to actually y'know, test their theories with science and actual equipment, while Scott Wasson just regurgitated what AMD spoon-fed him, despite clear evidence that contradicted what he was told.

You mean Ryan and Allyn didn't run to Tom Petersen for a their new software and regurgitate his PR notes like always.

I agree PCPER was deffo spoon fed the PR BS bcoz no other site except PCPER said ghosting was there. And PCPER to this day have not provided a proof or video to show this.

I stopped coming here after PCPER started using FCAT vs Frapps and vice versa again, but after nvidia start horrible frame times PCPER stopped using FCAT and started using frapps again bcoz it slows down AMD GPU whilst running FRAPPS

Quite few other sites said the same thing as here at pcper(about ghosting). Check your self.

Ghosting has nothing to do with VRR rather the panel handling RTC and RTO.

Allyn made the assumption that ASUS ROG and BenQ were on the same panel which they clearly are not. TFTCentral had verified prior to PCPerspective initial article. He is yet to correct himself or the countless assumptions he made in the comments pertaining to what is AMD/Nvidia issue or a panel hardware issue.

‏@TFTCentral Confirmation that the BenQ XL2730Z is using an AU Optronics M270DTN01.0 TN Film panel. Different to the Asus ROG Swift PG278Q (M270Q002 V0)
9:53 AM - 11 Mar 2015

If he would have looked at the TFTCentral review he would have seen that the Asus Rog Swift ghosts. That review was done when it was released and is a much more thoughtful review about the panel.

A simple google search would have brought up the review which was done in JULY 17 2014 10 months ago showing the Asus RoG swift and other G-Sync monitors that been reviewed showing ghosting.

Asus ROG Swift PG278Q
Simon Baker, 17 July 2014 (Updated 13 March 2015)

That wasn't the case though. Ryan and Allyn had a preconceived notion and pushed it while ignoring FACTS that have been around and available to anyone with a internet connection and the ability to search for Asus RoG Swift review.

Of course. PCLab, which we know will make every dirty trick to please NV and Intel, as editor once bought a cheap perishable laptop with AMD's chip. Others are quoting from PCPeer ;)

Second scaler means next $20 to the final price. Just for simple, single HDMI output.

Release anything less, at any price, and it will not be considered.
