G-Sync/AMD Free-sync

[Random member 231113]

So this is a continuation of my last thread/post where I discussed what you need to run AMD Free Sync. One of the most important questions I have is can you run this feature with HDMI or can you only run it will a thunderbolt display port cable? I am asking this question because I have read that you can only use this feature if you have display port but AMD’s website states that you can use it with HDMI so I am very confuse now. Also because most laptops don’t actually have display port and only support HDMI so I am very limited to gaming laptops. NVIDIA’s website says that G-sync is supported with HDMI as long as you have a 20 series and above. Can someone please explain this whole process to me so I don’t make a costly decision?

if you display and graphics card has hdmi 2.1 you will be able to use gsync.

What gpu are you planning on using? if it's nvidia then use this just to make sure there is no issues like flickering etc

NVIDIA GeForce G-SYNC Gaming Monitors

if using amd it's a bit tricky.


Anotehr thing is when a monitor comes with a gsync module inside it amd graphics cards will not be able to use VRR.

better to explain what you need like what monitor specs, panel type, graphicsd card (nvidia or amd or intel) then we can help you with twhat you need.

Hi thanks for the replay
Is g-sync have the same functionality as AMD free sync. MY model number of my monitor is dell s2721dgfa. I planning to get a nvidia rtx 3050.

I used the website like you told it picks it up that it does have g-sync. But how would i know if my monitor has a HDMI 2.1 cable. I know it has a HDMI cable and display port cable

For your purposes gsync and freesync have effectively the same result, but internally they operate different which doesn't really matter to you. What you need to know is gsync is for nvidia and freesync is for amd as a baseline, then from there check if your monitor supports which technology vs which graphics card you have. Nvidia graphics cards in general can support both (but there are edge cases where freesync doesn't work or doesn't work well), whereas amd cards cannot support gsync.

Hdmi vs display port is up to the manufacturer and the target maximum refresh rate your monitor can output. In general hdmi and display port both support high variable refresh rates using gsync and/or freesync, it is up to the manufacturer to decide if they support only one or both on specific monitor models. Display port generally is superior to hdmi because it has more bandwidth which means support for higher refresh rates so usually connecting via display port is more likely to work in getting the monitors high refresh, but again check which port the manufacturer has designated.

In your case the dell s2721dgfa supports both freesync and gsync compatibility so you don't need to worry about which card you are using, your next step is to check which display connector (hdmi or display port) the manufacturer has enabled support for high variable refresh rates and use that connector and cable type, for the s2721dgfa both connectors support high refresh rates but you should prefer the display port because it supports up to 165 hz whereas the hdmi only supports up to 144 hz.

Thanks for the clarity
So if i use a HDMI cable with my NVIDIA graphics card everything should work perfectly right? Also is a RTX 3050 fine for G sync? Also would i just need to use my gaming laptops nvidia control panel to activate the g sync function?

Hdmi will work but only up to 144hz and not 165hz on your specific monitor.
Rtx 3050 will work with gsync.
Yes you use the nvidia control panel to enable gysnc and then also set the maximum refresh rate. It is two separate settings.

What do you think the FPS will be like as the RTX 3050 is really good right?

Also is there really any diffrenece between 165Hz and 144Hz

That's dependent on the game you play and the graphics details involved. Overall a 3050 is not a strong card for current games, it's workable but you should try look at getting a 3060 or equivalent, if not better, instead. If your card is too weak vs the graphics detail you are using, you won't be seeing the high frame rates that your monitor is capable of outputting.

This depends on the individual, generally speaking 20hz difference should be somewhat negligible but typically having more is better. It's basically free performance you're leaving out.

What would you recommend me to get in place of a 3050 RTX

Unfortunately I won't read that in detail, but based on the title and what I posted earlier, gsync will work with hdmi with the caveat about bandwidth and manufacturers choosing which connector to use. Forza and fps games will benefit from gsync and/or freesync, minecraft maybe.

Look at an rtx 3060 or better, dependent on your budget. If you don't have to use nvidia, you can consider a 6600xt or 6700 from amd and use freesync instead of gsync.

So basically its limitations as you discussed as just having a max refresh rate of 144Hz instead of 165Hz? One article i read said you should rather use HDMI 2.1 cables. You see my problem is not a lot of gaming laptops have display ports and that is the reason i wanted to try HDMI. And the ones that do are way too pricy . Although there was one laptop that had a display port it was some ASUS Tuf gaming f15 i7.

Yes it's the available bandwidth. The cable isn't going to do anything in terms of gaining performance, at best a quality cable can only match the hdmi version of the connector and/or the monitor at the lowest common denominator. Getting an hdmi 2.1 compatible cable doesn't magically upgrade your monitors hdmi 1.4 version to 2.1

So i dont need to worry of getting a new HDMI cable? Becuase isnt its the graphics card that does the work and not the HDMI cable, doesnt the HDMI cable used to transfer data?

You wouldn’t notice the difference between 120 and 165hz.

Have the same monitor (running Freesync on a 6700XT using a DP cable).

If you already have an hdmi cable then just simply try it, if it doesn't work then buy a new one that is compatible.

Why do you want to use G-sync in the first place (if you don't mind me asking)?

RE G-sync over HDMI; I would recommend not even trying. With the right card (you will need HMDI 2.1, which you are unlikely to have access to) and the right monitor, it can be done, but save yourself a lot of trouble and do it via Display Port OR - and I only figured this out recently - it can be done via USB-C (assuming you have this capability on both ends of the chain, which is of course not guaranteed).

As for the 3050, the recommendation to at least get a 3060 is good advice - I have a 3060 in my laptop, and it's perfectly serviceable, but I'd definitely have gotten something a bit beefier (especially in a laptop, since the GPU can't be upgraded).
