Freesync can work with nvidia?(I have problem with g sync)

[Annihilator]

Hi all.I tell you the story.

I have problem with my g sync on my asus rog pg348q with tearing and flichering with g sync.

I not know if all asus have this problem, need investigate it or if is the software with the new nvidia experience, but i see the new lg with 38 inch monitor and want change with it.But my question is: work the freesync with nvidia or need activate the v sync with it?

Because not trust anymore the asus now about monitor and notebook, i have notebook too and have problems with keyboard(cant press 3 buttons in same time), and is for gaming.

But the asus still good on motherboard.


Someone can tell me if freesync need force me to buyng amd or can disabled it?Or if exsist another 38 inch monitor ultra wide with g sync?

Thx in advance :)

Edit: The new monitor i want is: lg 38uc99.

Device Manager usually will say Generic PnP for your Monitor.
However that should be defined model-wise under Devices and Printers
There really is no Driver for a Monitor. When those are available for download, it is usually just a unique RGB Profile to help ensure the OS RGB Profile is correct for your particular Display.

Most likely your issue is that you have Custom Resolutions listed; get rid of all those.

Also check under Change Resolution in NVIDIA Control Panel.
Try changing Output Format to something other than RGB; such as YCbCr422

No it wont work you will get screen tearing. G-Sync works with nivida. Freesync is for amd.

Thx for responses but i got to sleep and not know how much time i have today.

In any cases i have tryed to modify on nvidia control panel that option but not have other format over the rgb, show only that, and the resolution is native 3440x1440.

Edit: In this case is possible the cable have the issue?Is lindy brand tipically can have the problems this brand.Not remember if is the cable included in the monitor but i think yes.

Edit 2: I have tested new cable but not working.No signal.

[Annihilator]

Any other solution?I have tried all but not work.Maybe if i buyng a new displayport cable 1.3/1.4 solve this problem?

Edit: I think now is 1.2.

Edit 2: I have plugged 3.1 usb need maybe unplug it too from monitor?Not is connected to computer.

The cables should be fine, if the Display is technically working with a certain cable, not flicking black/blue or discolorations (as that is the sign of a failing cable or perhaps a bad connection; more typical for HDMI) then I would say the cable itself is fine. You can get a higher spec'd cable; but the one that came with the display should be fine for that max support res & refresh. As for say DP 1.4 spec, that is for 4K and 8K and also higher refresh rates at those higher res; so that won't help your situation.

I would have a look at these:

Maybe try a single GTX 1080, DDU out the Drivers and try a clean install of the latest 373.xx ones.

Also maybe reset the monitors menu settings all back to factory defaults and go from there.

If the issue persists; might want to register your product serial# with ASUS Support (make a free account there) and Contact them about this further should you be unable to resolve it.

EDIT:
The USB is just to power the Ports/Hub on the Display; that will not interfere with how it displays, etc.

I have this problem from fresh install windows i not think is the driver honestly.At start i not have installed the new nvidia experience but the problem still one month since too.

The flickering on blue in certain cases i already have it from day one.

For that reason i sayd maybe is cable?I have tryed with 1 card too with clean driver one month since but nothing.


On the menu on the display if i tryng to overcloking 100 hz continue to say 60 hz on main menu.

[Bad 💀 Motha]

So when you change OC=ON + Refresh=100
Does the LED on the bottom of the Display not change to RED?
That indicates the 100Hz Refresh + GSync
If you change this all while the PC is running, restart the system.
As then such refresh changes will not apply to where your PC can detect what is available.
After a reboot, the 100 Hz Refresh should now be available in Windows and NVIDIA Control Panel; without any manual additions being needed, such as Custom Res+Refresh

[Annihilator]

Is already on red the led.I see the led changing only if i disable or enable the g sync or not have signal(not the overclock).I have already have OC on ON(but not change nothing if is off and, in certain times, the on disabled itself).But the hz still 60.I can reboot the computer now but, honestly, i already have test it i think.

[Bad 💀 Motha]

Then I would contact ASUS Support. Especially since you saying it had some issues from the start. Sorry we couldn't be of more help here.

[Annihilator]

I have reboot but nothing happens.I think is the monitor because not think is the gpu or no?In any cases np.Thx for try to help :)

[Annihilator]

During wait i have test more thingy and i have found how enable the overclocking, but not is a real 100hz, if i tryng to up to real 100hz, not the overclock, i see vibrating words.Weird thing.

But, finally, the have found the options for enable 100hz.But the monitor cant handle it i think is the monitor the issue with this test.

And the problem of the tearing and flinchering still.


Now i contact the shop on the weekend maybe.

[Bad 💀 Motha]

Just replace the Monitor; if it can't handle OC=ON + Refresh=100HZ (like it is supposed to; when using DisplayPort) then it's fair to say it is faulty.

[Annihilator]

I not have another same monitor to reach 100hz, have only one old monitor on 60hz, need send it back on the shop.In any cases thx again :)

[Bad 💀 Motha]

When I say replace, I mean contact ASUS Support and have them replace it.

[Annihilator]

Sorry for the delay again.Yes i want replace it but i contact the shop because i have more guarantee(is a famous shop in italy and i buyng from that on over 10-15 years).

Thx :)
