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

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.

So tempting (4K IPS, 144Hz), but must resist...

I thought that you can't even get 120Hz at 4K with macOS ?

This is the ultimate large screen "Dark Mode" macOS monitor.

Out of my price range though. Would have to be a lottery winner to get this one. Or maybe when the newer models come out next year and the prices on these drop significantly.
