PC Drivers & Software

[lefty123]

Windows 11, running latest drivers (22.5.1) and with an RX570. 
Freesync Premium Pro is "ON" in the monitor settings.

However, AMD software shows "Adaptive Sync Compatible" when I believe it should be showing "Freesync Premium Pro"

Anyone know how to fix it?  I've seen may others have the same issue with this monitor and I haven't found any solution. I don't think Dell care and I really don't even know if AMD are aware of it?

Howdy!

The FS Premium Pro implementation appears to be a problematic topic on some Dell monitors. In relation to the S3422DWG their community manager says:

---

There are other users also reporting that the Radeon Control Panel calls the S3422DWG, Adaptive Sync Compatible. But those users started a game. Within the games settings they saw, Freesync Premium Pro. So this sounds like a Radeon driver issue versus a hardware malfunction of the S3422DWG.

The circumstance that the monitor does only show up as "Adaptive Sync" might just be a bug in the GUI.
On the other hand, it is hard to tell whether or not Premium Pro is actually working in the background or not. Maybe Dell just screwed up the implementation ... which, of course, did not stop their marketing from touting the feature.

I hope there will be a solution for this topic since I actually plan to switch from Nvidia to AMD in the next weeks. My S3422DWG is running in Adaptive Sync with my GTX 1070 Ti at the moment. And I am still unsure if FS Premium Pro will even make any practical difference at all on this monitor.

Yes, I think its a bug. I hope someone actually looks into this. I did report it as a bug in the AMD video card software. Hopefully someone sees it and applies a fix in the new drivers, but it appears to have been like this for months, so won't hold my breathe.

I've got two of these monitors, the screenshot is from my wife's new PC with the RX570.

My new PC (haven't set it up yet) will be running an nvidia 3080, so I still want to take advantage of the displays Freesync. How well does gsync go with this monitor, have you noticed any bugs? Otherwise I might need to go get an AMD equivalent, which would be kind of annoying as I've just bought the card and haven't used it yet lol

I hope it is, and not a faulty firmware or even hardware implementation on Dell's side.

Connecting a FS Premium Pro monitor to a Nvidia card (preferably via Display Port) should trigger the Adaptive Sync mode, given by the VESA standard. That should theoretically allow us to use both VRR (Variable Refresh Rate) and LFC (Low Frequency Compensation). Hence, there should not be any significant tearing or frame skipping, even though you are not using the native AMD implementation. To my knowledge FS Premium Pro is more or less a feature pack of VRR + LFC and some HDR tweaks. But VRR and LFC themselves are already being delivered through the generic VESA implementation. So yes, in theory it should be fine running the monitor with a Nvidia card.

Personally I am pretty happy so far, as long as I stay above 60ish FPS. Not sure if LFC is actually running on my end, with a 1070 Ti. I will try to verify that and posts the results asap.
Some say that Nvidia + FreeSync monitor in Adaptive Sync may introduce some flickering issues. Thankfully I didn't notice any so far.

Other than that, maybe some expert here in the AMD community can share more details about the benefits of FS Premium Pro, compared to generic Adaptive Sync with a AMD or Nvidia card?

@lefty123 

Have you tried turning freesync off then back on from monitor. Or tried with a hdmi cable ?

[Pipistrello]

I just switched back and forth in the UFO test, disabling and enabling FreeSync in the menu of the S3422DWG. Pretty hard to tell a difference. Since there is no significant tearing or stuttering in practice I would assume that my system (Nvidia 1070 Ti via DisplayPort) is running in the generic adaptive mode as specified in the VESA standard. Not sure about LFC though since I cannot track the actual refresh rate of the monitor. There is a frame rate option in the menu. But it does only render the max refresh rate of my system (144 Hz), not the actual refresh rate of the scene. Does that mean that VRR is not even working at all? Hard to tell from my end ...

With all that uncertainty I would say it is safer to stick with an AMD card instead of Nvidia. However, the results may vary from user to user and system to system. My 1070 Ti is surely not the latest. Things might run smoother with more recent Nvidia cards. I guess you have to try and compare for yourself.
