AMD’s FreeSync and Nvidia’s G-Sync are must-have options for PC lovers. Every syncs the refresh price of appropriate shows together with your graphics card‘s body price, offering completely easy movement in most conditions. The tech has even come to televisions like (most of) LG’s OLED line.
Most often, PC lovers use FreeSync and G-Sync over a standard video connection like DisplayPort or HDMI. However what about USB-C? The USB customary is able to carrying video to a show, and USB-C hub screens at the moment are an awesome different to a show paired with an exterior dock or hub. Is USB-C appropriate with FreeSync and G-Sync?
The brief 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 primary function required for FreeSync, G-Sync, and different Adaptive Sync requirements to work over USB-C. It’s known as DisplayPort Alternate Mode.
USB-C gadgets that carry video do it with DisplayPort Alternate Mode. This carries a DisplayPort video sign over USB and works like every other 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 should have a USB-C port that helps DisplayPort Alternate Mode. That is price 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 identify, and Adaptive Sync is an elective a part of the DisplayPort customary. Which means a FreeSync show with a USB-C port that has DisplayPort Alternate Mode can simply help 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 a whole lot of screens, together with cheap shows meant for workplace use quite 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 additional particulars to think about.
Not all variations of G-Sync are the identical. G-Sync Final and G-Sync shows have an extra proprietary module contained in the show that syncs with an Nvidia graphics resolution.

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 are usually not 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 help G-Sync over USB-C with out concern.
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 help to its built-in graphics with the Intel Tenth-gen Core “G” collection 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 once I put it to the check. I attempted a Samsung Galaxy E-book 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 Heart, 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 concern and can replace if the corporate supplies a response.
Why isn’t USB-C extra widespread?
The technical basis of USB-C’s DisplayPort Alternate Mode can deal with AMD FreeSync and Nvidia G-Sync, however you will have a tough time discovering a USB-C monitor with official help.
Why? It comes right down to advertising.
PC avid gamers, the group that cares most about Adaptive Sync, tends to stay with customary, 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 may flip a monitor into an all-in-one hub for USB, show, and Ethernet. These looking for such a monitor typically don’t care about FreeSync or G-Sync, although, so productiveness screens don’t at all times trouble with help.
That is altering. Adaptive Sync will not be tough to implement, so increasingly more screens are including help. For now, nevertheless, you’ll need to preserve an in depth 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 help for FreeSync and/or G-Sync.
I’d additionally suggest sticking to a direct connection between your PC and the show. Which means no splitters, hubs, or adapters.
