Y740 w/ 1660ti Gsync is not available and does not run in background.

2019-08-16, 17:34 PM

Yes there is another thread about this, but this is becoming a common problem and the thread title for it is not specific enough.

 

the new non-RTX series Y740 does not have Gsync enabled. it is not running in the background either, neither does nvidia control panel list it as available.

 

I have yet to come across a y740 1660ti owner who has gsync listed as an option in control panel, despite the lenovo store still saying it does, and confirming the IPS panel used is the same as the RTX ones.

 

if you own the new y740 with 1660ti (not rtx) you can check nvidia control panel and see if you have gsync

 

You can also try to enable it via the pendulumn demo, but the screen flashes red and doesn't keep it on, and tear is very obvious at all fps ranges with vsync off and orbit speed set high.

 

I have yet to find another y740 1660ti owner on these forums who has the gsync option showing, and gsync is what prevents those screen tears at oddball frame rates.

I just posted  a similar thread, hopefully they become aware of the issue and have a response.

I'm having the same problem, cannot find g-sync anywhere, I just got it about a week, should I return it?

If G-Sync is a must have "life and death" situation, and you were promissed G-Sync, then yes, return the laptop for full refund.

Will this laptop work with an external Freesync display? If so, I don't care about having G-sync on the built-in display, as I would just use it plugged into an external monitor for serious gaming.

I don't think so unless it has a mini display port (it might, I returned mine so I don't remember/can't check). Keep in mind HDMI freesync isn't supported by Nvidia because it's AMD proprietary and requires AMD hardware/software. So if the panel you're going to connect is something without display port, it won't work.  I tried a g-story 17 inch portable 120hz freesync panel and because it only has HDMI and type c ( which uses HDMI alt mode, not display port alt mode) it wouldn't work even with a thunderbolt connection.

It does have a mini displayport. At least, specs list it as having one. And the 1660ti is listed as supporting freesync monitors (which nvidia has supported since jan 2019 on some compatible models)

Then connecting a display port to mini display port cable and a display port based freesync monitor while in dedicated graphics mode should work fine.  Just, again, know that HDMI freesync monitors won't work, and a mini display port to HDMI cable won't solve it.

Thanks. Then I will keep the laptop and use an external Freesync monitor that's Nvidia compatible.

Hey, just wondering if you were able to get g sync to work with the external monitor. I'm looking to make a similar purchase so I want to know if it will work or not. Thanks
