Hi,
I recently got an ASUS VG245HE external display, to which I'm hooking my MBP 16" for various usages.
I see it supports Freesync, but option is grayed in the AMD settings.
Is Freesync just not supported?
Currently using MBP 16" with 5500M 8GB.
Thank you

I had a hard time getting this to work, HDMI through a USB-C hub did not work for me and it capped the refresh rate to 120hz.
Now I have a DisplayPort (Monitor) to USB-C (MBP) cable it works perfectly. I imagine a hub with displayport should work too or a TB3 dock.
So yes free sync is possible and ALL usb-c connector are wired straight to the DGPU.

Thanks for your answer.
My monitor is Freesync compatible but doesn't have a Displayport entry... Should I just try a HDMI to USB-C dongle that isn't a hub?

I'd say that is your best bet, I tried various hubs/adapters with my 16" to USB-C > DisplayPort and while they seemed to work just fine freesync was grayed out with my Phillips 436M6 that does support Freesync. It also did not work via direct USB C > USB-C input which this monitor has. A Plugable brand USB-C > DisplayPort cable from Amazon was what worked for me. So i'm not sure the standards or requirements for it to work with HDMI but a basic cable is what ended up working the best for me.

You can also check if your external display has any firmware updates on it's online support page. Some displays actually do have these and you update them usually by putting the firmware on a USB stick and plugging it into a USB port that's in the monitor  |

Thanks for your answer. My monitor is Freesync compatible but doesn't have a Displayport entry... Should I just try a HDMI to USB-C dongle that isn't a hub? I have the same problem, got this monitor Acer KG241, it has no display port entry, only HDMI and VGA, it supports Freesync but I can't turn it on in the driver's settings I have a MB Pro '16 late 2019 with a Radeon 5300M and I'm connecting to the monitor with a usb-c hub (apple original) and hdmi 2.0 cable. Any tips? |

I guess you should try a "usb-c to hdmi cable" and no usb-c hub or adaptor.

So, I've tried a usb-c to hdmi cable and still id shows Not Supported in Radeon Software. Weird thing is that I checked CRU and it does show Freesync information:  Still It says not supported in AMD Driver. I wonder if it's not a problem related to the driver itself...  EDIT === Adding more info here.... it seems that amd software does not like that the "connection" in seen as Displayport, maybe it expects another displayport to be on the output? If I create a new display by emulating this one's EDID but changing the destination connection to "Passive dongle DP to HDMI" then it sees it as freesync compatible.   So it seems that radeon software does not like displayport input > hdmi output, neither active dongle input > hdmi output, but could work if it detected it as passive dp>hdmi dongle. Don't know how to get this to be detected that way though (maybe could hack edid?)... thoughts? |

Have the same issue with the same screen, and have been trying different solutions without managing to hack it. Did you figure something out?

Then going into any game and capping the framerate to anything that is not a multiple of the refresh rate for example 100 FPS cap on 120 HZ monitor setting. There is no judder/stutter which means freesync works. BUT the difference here is you're trying to do it with HDMI, which I don't think works. The ONLY way I can get it to work is USB-C to DisplayPort. |

Freesync is supposed to work with HDMI according to these official specs: www.amd.com/en/technologies/free-sync-faq#faq-Does-AMD-FreeSync%E2%84%A2-technology-work-over-HDMI%C2%AE?AMD is very specific in this, that it doesn't even require HDMI 2.1. There are monitors which are Freesync certified that do not have displayport. |

It does say MANY, not all. So best check that before buying a monitor to use with HDMI and VRR.

Sorry I never got back to you guys.
I actually bought two different USB C to HDMI cable that advertised as thunderbolt, displayport, etc. compatible. But it never worked...
