Is it possible to configure the native mode at 60Hz (games running at 60fps will thank for that) and have G-Sync in the range of 60fps?

Hi,

I could add a special resolution through the Nvidia Connfigurator: 1920x1080 @60Hz

Yes... the problem is: will be used and recognized in-game? Can you test some games for me, please? Thanks a lot
IMO 60fps are perfect for this HW and will grant a perfect smoothness at 60Hz video refresh (and G-Sync should take care of occasional frame drops, in my ideal goal). I'd like to buy this laptop and set default ("native") resolution at 60Hz instead of 75 (too much fps for many games).

Set screen refreshrate at 60Hz. Run Hitman benchmark but I could not see at what refreshrate. What tool could I use for that? MSI Afterburner only shows framerates but maybe I miss a setting in this tool.

Good question...

I remember my G751JY was set at default at 75Hz 1080p native.... I created a custom screen like you and set it as desktop default res. Then I upgraded nVidia drivers and from that moment on my "native" mode was 60Hz for the new drivers. Maybe the trick will work also on G752VY.

BTW, is it possible to disable Optimus from BIOS/UEFI (if enabled) on G752VY, and use always the nVidia card?

There is not Optimus for G752VY...

nVidia just changed it in their drivers which had nothing to do with what you did. I always run my panel at 100hz and for a while it was defaulting on new drivers to 75hz and then all of a sudden it went back to 60hz default.

How about limiting games framerate to 60 with something like Nvidia Inspector, and then keeping g-sync enabled. It oughta work, methinks.

Mmmh, I wasn't sure indeed and always thought it was a bit strange (= didn't expect that) but why should nVidia arbitrary change default Hz from driver to driver then???
Once I rolled back to old ones but it kept 60Hz however instead of initial 75Hz, so I'm still not completely sure about this...

You mean latest drivers set G752VY panel to 1080p at 60Hz finally? This is a good news to me ;)

Exactly what I had in mind... 75fps are hard to keep with the ultimate AAA games. 60fps are good enough and all I need, but I need to set display frequency to 60Hz for perfect smoothness. G-Sync then will take care of occasional frame drops within the ~60fps range.

g-sync sets your monitor to variable refresh rate, and should sync to whatever framerate your game is running at, so therefore you should not need to setup any additional screen modes outside the games.

Did someone ever try to "lock" max 60fps with nVidiaInspector and the like + G-Sync enabled?
No need to burst to 80-90fps just to increase GPU heat...

How?

Ah! Thank you!
That's much more useful! ;) All I found was indeed a MS doc about EDID modifications: https://msdn.microsoft.com/en-us/library/windows/hardware/jj133967(v=vs.85).aspx
Mmmh, I wouldn't overwrite the .inf if Windows registry trick is enough... I'll try (a restore point first and then) the CRU.exe and report back.

Set native mode to 60Hz, with G-Sync!

no prob... native 75 or 100 is much clearer and sharper but temps are little bit higher...

60->75Hz I see no difference and it's better for me having games running 60fps with 60Hz range video refresh (+ G-Sync "corrections" with occasional framerate drops)...
There are also some game engines that have troubles running at more than 60fps.

If you still want a higher refresh rate for the desktop my suggestion is to add a custom resolution through nVidia panel used for desktop only, leaving at 60Hz the native mode for gaming with 60fps goal in mind...
Image definition, colors and brightness can't change using 100Hz: it's just more eye-relaxing theoretically.

I have a hard time with this comment. Saying that you can't see a difference between 60 and 75 is tantamount to the arguments of console players who say you can't see the difference between 30 and 60. There is a very palpable difference between 60 and 75 while games look just amazing in the 75+ range which your panel can do. I have been running my panel at 100hz almost since I got my G751JY at launch and now 60fps looks a bit choppy to me as I am so used to 75+ fps. If a game has issues with higher refresh rate all you have to do is select a lower on in the options. I have not come across a single issue yet while gaming on my 100hz panel and there is a reason why gamers are moving over to 144hz panels... because it looks so much better!

You misunderstood me. As I said, can't see the difference on a desktop at 75Hz. Of course in-game is different, but 1) ROGs laptops can't handle 75fps in many AAA games at very high/ultra settings, 2) some engines (Skyrim comes to my mind, but also others) do have timing/physics issues over 60fps
But hey... everybody are free to do what they want with their PC. My goal was setting native res to 60Hz and that's all I need. Playing at 60fps on a 75Hz refresh will of course result a bit choppy since there is no sync. Playing 60fps at 60Hz = perfect smoothness (as well as 75fps/75Hz, the more the better but with a 1:1 proportion...), which is G-Sync work BTW...
