Workaround: FreeSync on nVidia GPUs

[humbug]

You got me going with the title of this thread, i have a Free-Sync Screen. :O

Maybe it true I praise Nvidia for giving us G-sync as am happy with my G-sync monitor and my G-Sync gpu..

As I don't really see a problem
If you own a Nvidia GPU then buy a G-Sync monitor
If you Own an AMD GPU or going play an xbox on it then buy a Free-sync monitor

G-Sync Screens are mega money, far too expensive for what you are getting, they are not worth it IMO.

Unless you get a b-grade one for a steal that's going strong 2.5 years later! The XB271HU is still going for £600 yet I bagged one for £390. It has minimal IPS glow/no backlight bleed and only a minor firmware issue that very rarely rears it's ugly head (resolved with an alt-tab).

In general however the premium it costs is ridiculous.

Yes they are, besides, you went in with the devil eyes wide open mate!

I did, but they start at £400, in fact the cheapest G-Sync screen at £400 is the same as my Free-Sync screen, which was less than half the price.

 

[Sin_Chase]

How you expect from AMD to support something that didn't existed on normal graphic cards until that point?.

Invest some money in R and D and develop something?

GSYNC wasn't a gift from the gods, and it didn't rely on on VESA standards being developed.

eDP VRR was developed into the DP spec as a result of revealed demand following GSYNC.

You think VRR would have existed in DP so soon?

Although I agree Sin, can we all refrain from the usual Free v G-Sync merry go round everyone please?

Didn't know the cheapest is £400, is your monitor a like for like 144Hz range etc though?

No its the 75Hz version of the same 144Hz Free-Sync screen which is the same as the 144Hz G-Sync.

OCUK don't stock it anymore but the 144Hz Free-Sync one was £200, its this one... https://eu.aoc.com/en/gaming/products/g2460pf

This is the G-Sync one, they are identical. https://www.overclockers.co.uk/aoc-...idescreen-led-monitor-gunmetal-mo-022-ao.html

I paid £150 for my Free-Sync one, great screen, with the Firmware patch it has a Free-Sync range of 36 to 75Hz

That you cannot run Vesa HDR1000 on a Nvidia card is not AMD's fault.

I am sure VESA HDR1000 can run on a nvidia card as Nvidia is a member of VESA DisplayHDR.

https://displayhdr.org/

I found G-Sync monitors Acer Predator X27 and ASUS ROG Swift PG27UQ had been certified HDR1000 compliant.

https://displayhdr.org/certified-products/

Nor that Nvidia isn't going to support HDMI2.1 because VRR is mandatory is AMD's fault.

Of course Nvidia will support HDMI 2.1 probably through firmware update just like Xbox One X.

If you were watched RTX 2080 launch event or read all slides and you will notice that Turing has DisplayPort 1.4 with DSC 1.2 feature that will support 4K 144Hz (31.35 Gbit/s), 4K 240Hz (54.84 Gbit/s), 5K 120Hz (45.66 Gbit/s) and 8K 60Hz (49.65 Gbit/s) that Pascal did not supported DSC 1.2 optional feature.

HDMI 2.1 also has same DSC 1.2 feature as DisplayPort 1.4 that will support 4K 240Hz (54.84 Gbit/s), 5K 120Hz (45.66 Gbit/s), 8K 60Hz (49.65 Gbit/s) and 8K 120Hz (102.2 Gbit/s).

On both Phillips 436M6VBPAB and AOC AG322CQ4 are tied up with the VESA DisplayHDR 1000 certification, so no Nvidia cards will work with them in HDR mode.

Can post another dozen links if needed on this subject.

Also you are confused. Nvidia has refused outright to even comment if they will ever support HDMI 2.1 because that forces VRR support, effectively killing Gsync outright.
If Nvidia wanted to provide HDMI 2.1, it wouldn't have gone to manufacture $800 HDR Gsync module, which is using a $500 FPGA CPU.
It could have simply wait few months and put HDMI 2.1. Also even the mighty 65" £5000 gsync TV doesn't have HDMI 2.1, and is pushed back to 2019, while Nvidia is trying to work around the bandwidth limitations of DP 1.4.

DSC1.2 is completely irrelevant when comes to true HDMI 2.1 support.

AMD on the other hand has said that there is going to be a driver update adding full HDMI 2.1 on all RX cards (Vega, Polaris) since January.

It'd be good with NV could be hacked to use Freesync without using 2 cards, as my AOC monitor is FreeSync but I jumped on NV for best bang for buk with a new laptop.

It is mandatory. Full stop.

https://www.overclock3d.net/news/gp..._radeon_rx_gpus_with_a_future_driver_update/1

Right now Nvidia has not committed to supporting HDMI 2.1, whose VRR tech is a mandatory portion of the standard.

If you read the long HDMI 2.1 spec document you will see VRR is mandatory to the spec, and no clauses exist to avoid it.

 

[sadbuttrue]

VRR is not mandatory and Rroff has already quoted the relevant section at hdmi.org. In case you need to see it on an official website, scroll the the bottom and read the second to last entry:

https://www.hdmi.org/manufacturer/hdmi_2_1/

 

[LeMson]

I thought it was just the bandwidth for 4k 144hz HDR full chroma that we were excited for with hdmi2.1, not vrr ?

Some people have been trying to claim that nvidia won't support HDR because they won't support VRR so they won't support 2.1 on the wrong assumption that VRR is compulsory

 

[willhub]

Is HDR not supported by Nvidia? Seems to work sort of just looks garbage. And no matter what HDMi cable I use, I can never get full 444, 10Bit, Full, never, that's on laptop and when I had a GTX1080.

That's incorrect. (Had to make this larger so people actually see it as it seems to have flown under the radar, but is important).

Both TFT Central and I (PC Monitors main guy) have reviewed the Philips 436M6VBPAB and checked HDR functionality using a modern Nvidia GPU. It worked without issue with HDR over DP. HDMI is another story. I've tested numerous 'FreeSync' or 'FreeSync 2' displays with HDR using an Nvidia GPU and it works just fine via DP, as it does with HDR capable AMD GPUs and systems.

Also the AOC AG322CQ4 is a DisplayHDR 400 display, not DisplayHDR 1000. The HDR implementation also works correctly on Nvidia GPUs, although it is by very nature rubbish (like all DisplayHDR 400 'fake HDR' implementations).

Ah yes you got me confused with HDR1000 on both G-Sync HDR and Freesync 2, interesting I don't know HDR on Freesync 2 will not work with Nvidia cards so consumers will need to buy either non Freesync 2 monitors/HDTVs like LG OLED or G-Sync HDR monitors.

If you can read HDMI 2.1 spec below and you will notice Nvidia is on the list and also a member of HDMI forum so Nvidia supported HDMI 2.1, you can see AMD on the list supported it with Polaris and Vega, also Microsoft is on list supported it with Xbox One X.

https://hdmiforum.org/wp-content/uploads/2017/01/HDMI_Forum_2.1SpecOverview_Jan2017_English.pdf

AMD and Nvidia support HDMI 2.1 with VRR would effectively killing all Freesync and G-Sync monitors but AMD and Nvidia can continue selling Freesync and G-Sync laptops with HDMI 2.1 to eDP like ASUS ROG ZEPHYRUS (GX501) laptop which has G-Sync display connected to eDP and it has HDMI 2.0 port.

If you read the long HDMI 2.1 spec document you will see VRR is mandatory to the spec, and no clauses exist to avoid it.

As of August 2018 enhanced refresh features have not been added to the master compliance test - it is also unlikely they will be a mandatory part of the specification as there are a range of devices where such features are irrelevant.

As things stand whoever said it is mandatory is wrong until they've finished rolling out the compliance test specification it is still an unknown but the official HDMI FAQ lists those features as being possible for manufacturers to support a mix of which makes it unlikely they will be compulsory.

 

[Wrinkly]

This will get very interesting when Intel supports VRR/Freesync via their iGPU.
