rtx 3080 hdmi 2.1 and gsync

[Frey]

I have a 4k monitor 144hz, but it has only hdmi 2.0 and display port.
I want to buy a new 4K monitor 144hz with hdmi 2.1.
Can I use Gsync with hdmi 2.1 ?

Yes

For GSYNC Compatible displays, that's when you need HDMI 2.1
For actual GSYNC displays, you don't need 2.1 because GSYNC is hardware based, GSC is software

what ?
I talk about GSYNC, and GSYNC ULTIMATE, and they work with display port only, but I don't know for hdmi 2.1

You don't want HDMI, period. You always want DP when using PC; it's required to use that for the GSync + 144Hz. The HDMI is never going to do that.

I want Hdmi 2.1 to use 4K 120hz without compression with HDR and 10 bits.
With display port I have to use 4K 120hz HDR at 8 bits.
So that's why there is hdmi 2.1, with a bigger bandwidth, can you understand ?
Bandwidth : hdmi 2.1 > display port 1.4
I will send an email to Nvidia....

But as far as the Monitor you have now goes, it will require you to use DP to use all of the full features that it advertises. How does what you have now have anything to do with HDMI 2.1 and it's capabilities? It shouldn't be DP 1.4. It should have DP 2.0

I will send an email to Nvidia, they will tell me if I can use Gsync compatible monitors with hdmi 2.1, and if there is a plan to use Gsync module with hdmi 2.1 and not only display port.
And the RTX 3080 is not display port 2.0 but 1.4

PC = Always use DP, never HDMI. DP is always better.
You can double check the brand makers specs of your Display, but if it's 4K @ 120+ Hz then it should have DP 2.0

Make sure you go buy a DP 2.0 Cable.

RTX 3080 have display port 1.4, STOP with DP 2.0.
And there is no display port 2.0. released.
and HDMI 2.1 > display port 1.4.
Can you stop.

HDMI 2.1 supports VRR (Variable Refresh Rate) which can run FreeSync and G-SYNC compatible (which is just another name for FreeSync tested to work with Nvidia cards)

The real G-SYNC modules builtin to monitors, such as G-SYNC HDR (Ultimate), will only work when using the DisplayPort and at least 30 FPS at all times.

You would want to use a DisplayPort cable version 1.4 and set the monitor refresh rate to 120Hz, if using 4K and HDR with 10-bit, as that would be the max bandwidth supported.

so my plan to buy a new 4k 144hz monitor with hdmi 2.1 is useless, thanks, I will keep my monitor, 4k 144hz gsync ultimate HDR10, and maybe Nvidia will release RTX 4080 with Hdmi 2.2 with gsync module compatible.

Thanks.

EDIT : I can use 4K HDR10bits with only 98hz, at 120hz it's 8bits, the limit of the Display port 1.4.
NO WAY to use HDR10bits at 120hz and 4K, that's why I have hoped that Gsync ultimate may be good with HDMI 2.1, Nvidia needs really to update the Gsync module.

HDMI 2.1 is 48 Gbps and support 4K 120Hz with HDR just like DisplayPort 1.4 already does anyways. Note there's DisplayPort 1.4 and 1.4a.

DisplayPort 2.0 will support 77 Gbps and duel 4K monitors or a single 4k at 240 Hz or single 8k at 85 Hz.

thanks, ok, I will keep my monitors, until Display port 2.0, and I will buy a new monitor then.
Thank you.
The problem, or limit, is we can only use 4K 120hz at 8bits with display port 1.4, but it's not really annoying, I'm sure than 99.99% of the people can't see the difference with 10bits.

I checked mine and yeah it's set UltraHD 4K 120Hz, Full Range, at 10-Bit (8-bit + FRC) with DisplayPort 1.4a.

So yeah it's not a true 10-Bit monitor, sorry I stand corrected in the amount of bandwidth supported by it. 10-bit would be at 98Hz. I personally rather the higher refresh rate when gaming.

yes, we really need display port 2.0, I have some good old games with 200fps at 4K, I will really appreciate them at 200hz :)

DisplayPort 2.0 was released back in June 2019. However, not for the public. Public release was meant for late 2020, but been delayed. Covid, newer motherboards, etc.

DisplayPort Alt Mode 2.0 also brings all of these capabilities to USB Type-C connectors, just as the industry prepares for USB 4. Which is another reason for the delay.
