PCPer Live! Recap - NVIDIA G-Sync Surround Demo and Q&A

Earlier today we had NVIDIA's Tom Petersen in studio to discuss the retail availability of G-Sync monitors as well as to get hands on with a set of three ASUS ROG Swift PG278Q monitors running in G-Sync Surround! It was truly an impressive sight and if you missed any of it, you can catch the entire replay right here.

Even if seeing the ASUS PG278Q monitor again doesn't interest you (we have our full review of the monitor right here), you won't want to miss the very detailed Q&A that occurs, answering quite a few reader questions about the technology. Covered items include:

  • Potential added latency of G-Sync
  • Future needs for multiple DP connections on GeForce GPUs
  • Upcoming 4K and 1080p G-Sync panels
  • Can G-Sync Surround work through an MST Hub?
  • What happens to G-Sync when the frame rate exceeds the panel refresh rate? Or drops below minimum refresh rate?
  • What does that memory on the G-Sync module actually do??
  • A demo of the new NVIDIA SHIELD Tablet capabilities
  • A whole lot more!

Another big thank you to NVIDIA and Tom Petersen for stopping out our way and for spending the time to discuss these topics with our readers. Stay tuned here at PC Perspective as we will have more thoughts and reactions to G-Sync Surround very soon!!

That was loads of fun. Tom's a class act! I like the way he had tons of opportunities to bash the competition, but it's just not his style. "Freesync is what it is" and then after the recording "Shepherds of gaming"

I didn't watch the entire video yet, but he is misleading about lag. I've seen a review of a different monitor on blurbusters and they showed that there is lag when you are running at a fps higher than 144hz. Once the fps were lowered below 144hz the lag went away.

As he said screen has a draw time of 7-8ms at 144hz. So when you get above that there would be small lag as it would wait for next frame outta the gpu instead of one that is there. I wouldn't say he mislead anything as he didn't say it wouldn't be there. As g-sync maintains drawing full frame and not drawing half frame. Really setting fps cap to 144 should be fine for mostly everyone even pro's that should be fast enough for mostly and FPS game.

When running in Gsync games dont go over 144hz or the monitors max Refresh rate. My Gsync monitor never breaks 144hz.

Great show Guys,

i have a question regarding G-sync and Windowed mode,

i have Heard that you cant run G-sync in windowed mode, is this due to a technical limitation or is it purely software issues and if a fix is in the works can it be commented on,

this feature i feel is very important to alot of multi display users to either run in windowed mode of full screen borderless.

if in multi monitor setup its full screen on the g-sync monitor, it should work as other 2 would be on dvi/hdmi which is separate and fixed refresh.

Unfortunately I missed the stream, but does anyone know if updates to the g-synch 'firmware' will be available via DP in the future? Obviously NVIDIA will be optimising the code and refining over time and would like to know that as a swift owner I could take advantage of those optimisations.

August 23, 2014 | 01:58 AM - Posted by arbiter

They never said that would happen but that would be something would have to done outside the DP spec, But the monitor does have a service port on the back least the 27inch one does so that could be where do the update if its like a usb port or something user can use.

As a company I think they rather sell you a new one for more $$$ then update it.

I am happy they said something about videos and movies. I hope this nudges them to make a g-sync video player or motivate someone to do it.

I have watched plenty movies on my monitor and via hdmi from my computer on to a tv and never noticed flickering or tearing.

You won't see it if you aren't looking for it mainly because over the years they have created software to help make it less noticeable. Also some players turn vsync on.

does the gt 730 support gamestream?

August 23, 2014 | 04:16 PM - Posted by arbiter

Um if the machine running the game has gt730 i would say no i mean its very low end part. IF its the machine playing the stream it would be able play the stream from a machine with a better gpu.

660's are lowest 600 tier that can do it.
750's are the lowest in the 700 tier.

I've been playing with a 750ti 2gb this week for gamestreaming and it works great. However a 660 is the same price (refurb) and about 20% better game performance. Just at a higher wattage .

So I have a combined suggestion/comment/question.

Now I believe I have read that GSYNC does not work with fullscreen windowed mode, (as apparently it requires full-screen rendering for it work) and I find this incredibly disappointing.

I find myself constantly tabbing and doing other things while I am also gaming (in particular MMOs) and losing the ability to multitask (traditional fullscreen tabing is not acceptable) is a major drawback in my opinion.

Thus my question is, could nvidia adjust/improve GSYNC to allow it to work without real fullscreen rendering?

The way I imagine it working is it would adaptively set the entire screens refresh rate to whatever application is in the foreground, regardless of if it is fullscreen or not.

Thus a game in a window or fullscreen windowed might might have its refresh rate varying while it is in the foreground, while Windows might be set to say 60 or 120, and then another application say a movie could be tied to the films framerate (say 24).

Ideally it would be able to switch to whatever is being interacted with, so a movie would gets its perfect frame rate, as would windows, and as would any game, or whatever else is being used.

In short, GSYNC everywhere, all the time without the need for an application to be fullscreen but just in focus.

Why are these monitor companies so reluctant or taking so long to implement software controls of the monitor settings, for example, why do I have to use the monitor's built in controls to adjust settings when so many monitors have USB connectors and 2 way communication?

Why can't I just adjust those settings within windows, and if possible, why can't I use one of those monitor calibration tools and have it automatically optimize the monitors own controls instead of applying some software correction that attempts to compensate for the display?
