AMD’s FreeSync and Nvidia’s G-Sync are must-have options for PC lovers. Every syncs the refresh charge of appropriate shows along with your graphics card‘s body charge, offering completely easy movement in most conditions. The tech has even come to televisions like (most of) LG’s OLED line.
Generally, PC lovers use FreeSync and G-Sync over a conventional video connection like DisplayPort or HDMI. However what about USB-C? The USB normal is able to carrying video to a show, and USB-C hub screens at the moment are an important different to a show paired with an exterior dock or hub. Is USB-C appropriate with FreeSync and G-Sync?
The quick reply? Sure, USB-C is appropriate with AMD FreeSync and Nvidia G-Sync. As is usually true with USB, although, there’s extra to it than that.
The minimal: DisplayPort Alternate Mode
[ Further reading: The best USB-C cables ]
There’s a fundamental function required for FreeSync, G-Sync, and different Adaptive Sync requirements to work over USB-C. It’s referred to as DisplayPort Alternate Mode.
USB-C units that carry video do it with DisplayPort Alternate Mode. This carries a DisplayPort video sign over USB and works like another DisplayPort connection. It adheres to the identical requirements and affords the identical options.
The monitor that you simply use and the machine you connect with it will need to have a USB-C port that helps DisplayPort Alternate Mode. That is value checking, as some laptops and screens embody USB-C ports with out this function. No DisplayPort Alternate Mode means no video over USB-C which, after all, means no Freesync or G-Sync.
Does AMD FreeSync work over USB-C?
Sure, AMD FreeSync will work over USB-C.
AMD FreeSync is mainly VESA Adaptive Sync by one other title, and Adaptive Sync is an non-compulsory a part of the DisplayPort normal. Meaning a FreeSync show with a USB-C port that has DisplayPort Alternate Mode can simply assist FreeSync over USB-C.
The good thing about FreeSync is its broad compatibility. FreeSync’s tie to Adaptive Sync means you’ll discover it supported on lots of of screens, together with cheap shows meant for workplace use somewhat than leisure.
AMD helps USB-C on a few of its present desktop graphics card line-up, such because the Radeon RX 6800 XT and RX 6900 XT.
Does G-Sync work over USB-C?
Sure, Nvidia G-Sync will work over USB-C – although there’s a pair further particulars to think about.
Not all variations of G-Sync are the identical. G-Sync Final and G-Sync shows have a further proprietary module contained in the show that syncs with an Nvidia graphics answer.

Gigabyte
These G-Sync shows require DisplayPort, and since USB-C sends video over DisplayPort, G-Sync Final and G-Sync ought to be appropriate. However there’s a catch: proper now, G-Sync Final and G-Sync shows will not be transport with USB-C.
G-Sync Appropriate, the more moderen and by far commonest type of G-Sync, is totally different. Like AMD FreeSync, G-Sync Appropriate piggybacks on the Adaptive Sync specification. A handful of G-Sync Appropriate screens, just like the Gigabyte M32U, have USB-C and DisplayPort Alternate Mode. These ought to assist G-Sync over USB-C with out problem.
Nvidia doesn’t provide USB-C in its present graphics card line. The GeForce RTX 20-series had USB-C, however Nvidia took a step again from the function for the 30-series.
What about Intel?
Intel added VESA Adaptive Sync assist to its built-in graphics with the Intel Tenth-gen Core “G” sequence processors. Intel’s Adaptive Sync works over DisplayPort which, as with FreeSync and G-Sync, shouldn’t be an issue.
Sadly, the function didn’t work after I put it to the check. I attempted a Samsung Galaxy Guide 360 laptop computer, which helps Intel Adaptive Sync, with Dell’s S2722QC monitor, which helps AMD FreeSync. Intel’s Adaptive Sync appeared energetic in Intel’s Graphics Command Middle, however Adaptive Sync didn’t work. The identical monitor labored completely with an AMD-powered Lenovo ThinkPad E545 laptop computer.
I reached out to Intel about this problem and can replace if the corporate gives a response.
Why isn’t USB-C extra frequent?
The technical basis of USB-C’s DisplayPort Alternate Mode can deal with AMD FreeSync and Nvidia G-Sync, however you might have a tough time discovering a USB-C monitor with official assist.
Why? It comes all the way down to advertising.
PC players, the group that cares most about Adaptive Sync, tends to stay with normal, full-size DisplayPort. Most desktop graphics playing cards don’t even have USB-C.

Dell
Productiveness screens typically have USB-C as a result of it will probably flip a monitor into an all-in-one hub for USB, show, and Ethernet. These purchasing for such a monitor typically don’t care about FreeSync or G-Sync, although, so productiveness screens don’t at all times hassle with assist.
That is altering. Adaptive Sync isn’t tough to implement, so increasingly screens are including assist. For now, nonetheless, you’ll must hold a detailed eye on the specs.
Bringing all of it collectively
Nonetheless a bit confused?
Right here’s the fundamentals. You want all of the next to make use of FreeSync or G-Sync over USB-C.
- A PC with a USB-C port that helps DisplayPort Alternate Mode and graphics {hardware} that helps FreeSync and/or G-Sync.
- A USB-C cable that may deal with DisplayPort Alternate Mode.
- A show with a USB-C port that has DisplayPort Alternate Mode and assist for FreeSync and/or G-Sync.
I’d additionally advocate sticking to a direct connection between your PC and the show. Meaning no splitters, hubs, or adapters.
