Gigabyte Z490 Vision D (Thunderbolt 3) + i5-10400 + AMD RX 580

OK. I'll set my target there. Is Monterey able to do promotion with a 144Hz monitor with that card?

144Hz should be just fine, but it may be necessary to first switch to a scaled resolution and then select the frequency from a pop-up menu. On my AOC Agon monitor, I can set 120Hz refresh rate with no problem, but it's only available at the lower 1080p resolution.

Isn't ProMotion on Macbook Pros a constantly changing refresh rate, on the fly ? Don't think any monitors we connect to a hack can duplicate that. It won't work on any Intel based iMacs.

"The ProMotion technology in the new MacBook Pro adapts the refresh rate to match what's on the screen."

"When you are reading a text document, your laptop doesn't need to refresh the display 60 times per second. In this case, the new MacBook Pro will decrease the refresh rate. As a result, the lower refresh rate will increase the battery life, and it will all happen invisibly for the user."

You’re right that ProMotion is a proprietary variable rate refresh (VRR) technology from Apple. But @sbushman18 appears to be referring simply to the ability to set 144Hz fixed rate on his monitor. He brought up ProMotion to demonstrate that macOS can support refresh rates higher than 60Hz.

On the other hand, if he is indeed looking for VRR support on his 144Hz monitor, that’s a different problem. VRR support on third-party GPUs has been very spotty if I recall correctly.

Yeah. I mainly want a high refersh rate option at 4k. I can do 120Hz at 1080p, but I lose HDR. I imagine my rx570 is the limitation.

It would be cool for the VRR feature to work too, but high refresh rate would be ideal even by itself. Once you get used to it, 60hz looks blurry. It certainly didn't used to!

Earlier this morning when I posted the screenshot above, I spent a few minutes comparing 60Hz versus 120Hz. I agree that once you see 120Hz (or higher), then 60Hz feels rough and jittery. Alas, my AOC Agon's native 2560x1440 does not support 120Hz, but the market trend these days is towards higher refresh rates. So I may be replacing one or more monitors soon...

Update:
The monitor actually supports 144Hz at 2560x1440, but not on macOS with AMD RX580. Will try a different GPU soon.

With the recent GPU flood, I am considering upgrading my RX570 4GB to something better. I have a 144Hz 4K 28" monitor with freesync premium and gsync/vrr. What card can I get that can do promotion, or at least 120Hz in the latest Monterey build (12.5.1)?

Anything plug-and-play? Rx 6700xt or RX6800 may be getting cheap soon.

6800XT, 6900XT and 6950XT works

@bricknewer Please replace your SSDT-DMAR.aml with the one I attached here and then try booting Windows via OC again.

Hi, sorry for taking so long to get back to you. This did not work for me unfortunately.

macOS Monterey supports VRR, at least up to 165 Hz VRR on Radeon 6000 series...but since my monitor doesn't have a HDMI 2.1 port, I only get VRR support via DisplayPort. As we know HDMI 2.1 also has VRR support.

My monitor has the ability to display the refresh rate at all times... on macOS it's mainly static at 165 Hz, but sometimes it goes down to 48 Hz during updates and such. And in gaming in windows, the refresh rate continuously changes to adjust to the frame rate... for tear-free gaming.

Awesome. I'm tempted to try this with my RX 6600 XT.

Update:
Just tried it with Ventura public beta on the same AOC Agon monitor via DisplayPort with RX 6600 XT.

It works very well!

SOLD. My next high-resolution monitor must be able to support high refresh rates.

LEFT: Default 60Hz
RIGHT: Variable (48-144 Hertz)

Several options to choose from:

I've been looking at this Viewsonic that's at a really low price right now. Too bad the 32" is curved. Don't want that for numerous reasons. Hard to believe they can sell an IPS 144Hz 1440p monitor at this price.
