Blur Buster's G-SYNC 101 Series Discussion

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

Unfortunately there's still not much choice around 4K G-sync and overclocking my monitor was one of the first things I tried - wouldnt even go to 61hz (pretty much flatout says it isn't OCable on the Acer specs too).

Ouch. Thanks for letting me know...

So what's the best way to set up Gsync now? its getting confusing with Fast Sync! is it still Vsync on and cap a few frames under the monitors refresh rate?

Guys, how to get rid the flickering stall issue (its like small brightness fluctuate) ex : in loading menu, sometime main menu, or heavy loading in openworld gameplay.
Is this only happen on TN Gsync panel?

How is your IPS Gsync Panel?
Which gsync monitor have completely zero flickering even on loading screen

Thx

Is this LCD inversion type patterned/lines flickering? http://www.testufo.com/inversion

This is caused when G-SYNC falls suddenly to 30Hz in menus, and this can cause slow LCD flicker from the positive/negative voltages of the LCD inversion electronics. This is more common on some TN panels, but it's invisible on my ASUS ROG PG278Q (I don't see flicker) so it doesn't affect all TN panels universally. IPS panels are less prone to this type of artifact, although they have somewhat more motion blur than TN.

Or is it a different type of flicker? (e.g. backlight brightness flicker)

Hi, my knowledge about monitor is minimal :D but as a newb trying to describe it, its like slight minimal brightness fluctuates/flicker in upper screen, most noticeable in loading screen maybe same issue with this article.

http://techreport.com/news/27449/g-sync ... some-games

Its very minimal flicker while in gameplay almost zero flicker, only i hate it when loading screen.

I think if the loading screen not flickering, it would be perfect gsync monitor for me.

Is the PG278Q has zero flicker even in game loading screen? Thankyou

Yes, it's partially related. That said, it is very LCD dependant on how they flicker at lower refresh rates (pixel relaxing, inversion vibility, etc) -- both cause flicker.

PG278Q is an older GSYNC monitor now.

Faster LCDs have less motion blur but likely more prone to the flicker issue. I would imagine that IPS G-SYNC monitors are less prone to this issue, and the good thing is that they can fall to extremely low refresh rates without visible flicker issues.

As far as I know, I haven't heard of strongly-visible inversion or flicker behaviors on these IPS 165 Hz G-SYNC monitors:

- ASUS PG279Q
- Acer Predator XB271HU
- AOC AG271QG
- Viewsonic XG2703-GS

IPS is slower response than TN, but your eyes might prefer the colors/stability of IPS. Many forum swear by these monitors.

Yes i want stability, im thinking to upgrade my current gsync TN panel to gsync IPS.

Thanks for the help Chief.

You're welcome!

Laptops usually use IPS screens and they dynamically lower refresh rate with static images without being noticed -- IPS has historically very well-suited to refresh rate power-management, and that has translated very well to stability during GSYNC operation as well. Current Apple iPads all use screens very similar to IPS, and their ProMotion variable refresh rate doesn't have any flicker effects. This provides more evidence that IPS screens are less prone to flicker-effects from VRR.

Hey guys, I have a question, the optimal way for the less input lag at the moment is still G-Sync ON and V-Sync ON in NVCP, right? But why I have to set framerate limit in RTSS to 141fps (144hz) if the V-Sync ON at NVCP is already putting my FPS limit ingame to 144fps? Do I need RTSS limit too? Thank you!
