Crawly news:

Some people I know and I take been working on this project after stumbling upon it.

In a nutshell Freesync tin be enabled over HDMI and some DVI on non freesync monitors ( YMMV)

Requirements: GPU that back up freesync

Latest crimson driver 16.10.1, we likewise know the previous driver works.

Latest CRU p2 beta, and able to follow the instructions

Directions and discussion can exist plant at guru3d in this thread.

For me on my LG29um58 I have both freesync and VSR working.

Merely idea I would share...if enough involvement I volition postal service the directions and all here.

/EDIT ten/10/2016

A little background on the three of usa that started working on this. OnnA uses CRT in his part of the earth and stumbled on this.

ToastyX the writer of CRU did non have a freesync GPU at all ( he obtained one a couple of days agone) nor a freesync monitor.

Myself: I practice not have a freesync monitor at all ( cannot afford one )

With this said we had to work together on the parts we each had. Which is why the original thread is a scrap jumbed though we did communicate some with PM and at ToastyX CRU forums besides.

I plan to purchase a freesync monitor in the coming months when I can afford to, then I can actually look at a freesync edid compared to non freesync but this will be months off. We just do not take enough information on freesync DP and actually HDMI freesync, hardware is our limitation or rather the lack of hardware every bit we practise this for fun and crusade we can just since we are not "reviewers" we do not go examination equipment.

I debated long and hard about releasing our findings to the public masses in the land we have it but decided that for some information technology would be a boon and worth it even if incomplete.

I thought about making a video guide only actually accept never made a video so do non know where to begin.

/EDIT 2 10/10/2016 We practice not know if you can enable information technology soandso monitor without really having it. And so all I can say it attempt it and work with ranges to find out.

/edit 3 10/ten/2016 Gonna work up a video guide once I figure out OBS lol. Just retrieve the things I practise in it, ranges are specific to my current hardware, the actual steps will exist same.

That's pretty cool looks like I have some checking to practice on my system to see if I can become this working, thanks.

I'm not ownership it. Ona even says information technology works with Nvidia cards on a CRT. Then goes on requite information technology his ain proper name - cosmetic sync or some such nonsense.

Clearly some people here don't actually understand how FreeSync works. Don't assume this is impossible if you haven't tested it. Otherwise, you're just filling this thread with nonsense. People want to encounter results, not theorize.

FreeSync works by varying the vertical blanking interval. ALL monitors support vertical blanking. Information technology's function of the video signal. It's how the monitor knows where one frame ends and the next frame begins. The only question is whether the monitor tin handle variable vertical blanking and longer blanking intervals. CRT monitors are basically controlled direct past the video signal, then this is more likely to piece of work with a CRT. LCD monitors without scalers and laptop screens might too work. AMD themselves even demonstrated information technology working on existing hardware.

The problem is most LCD monitors on the market accept scalers. LCD monitors with scalers are less probable to work without firmware changes because the scalers are usually designed to handle a limited range of refresh rates and timing parameters. The fact that some monitors are blacking out shows that it's really doing something to the video point and not but a driver toggle.

I can't exam this right now because I don't have a FreeSync-capable video card, but I have one on the way. I wouldn't have thought to exam this with a CRT, then OnnA deserves credit for that. Unfortunately, the simply CRT I take is an old fourteen" with a limited range, but I also have an LCD monitor without a scaler that I'd like to test this on.

ToastyX is confusing adjustable refresh rate with variable refresh rate. They aren't the same affair. And having a scaler shouldn't matter at all.

AMD demonstrated it on an EDP cocky refreshing panel, which guess what? EDP is what Freesync is based upon.

Really the presence of a scaler can in theory matter, since it can determine whether or not the brandish in question volition use its ain scaler (if one is present) or rely on the scaler in the GPU. If the monitor defaults to using its own scaler and this scaler isn't compatible with this alleged method, and then that could terminate it from working (that is assuming the method even works in the first identify).

ToastyX did actually produce some slightly more convincing evidence of this method working using the Windmill demo, which dissimilar the frame graphs that OnnA keeps posting, really does point that FreeSync is working.

Either manner though, I would definitely await for farther confirmation on this one

I'm non going to believe this guy when he comes right out and says he can't even test it because he doesn't have a freesync capable video card...

There's actually 3 different guys working on it and the guy you lot mention (ToastyX) has acquired a FreeSync capable card now (an RX 480 to be verbal), and confirmed it as working.

I haven't read the link yet, simply I can only imagine that this will drive LCD displays that have an OSD and a scalar, completely bonkers, trying to re-sync to the signal, EVERY FRAME. No wonder some of them black out.

Well shiiiiiiiiit.

ToastyX isn't one for trolling. I'll have to give this a shot tonight.

This is completely plausible.

For this to work on DP yous would need a monitor with DP 1.2a (supports the Variable Vblanking header). The scaler/TCON vendors ships their production with the header field intact rather than having two SKUs. If the monitor vendor and so isn't customizing the firmware to disable support for the VVblanking information technology could piece of work. AMD shouldn't exist policing this on their side either because of the way monitor and video card interactions are spec'd to piece of work. That is to say the monitor reports it'south capabilities to the video card via EDID. Notably this is why Nvidia G-Sync is a product that is not following established specs. Anyways, AMD's Freesync implementation *should* accept the monitor capabilities without question. There could be some negatives though. A not-Freesync branded(ie AMD certified) monitor will not take any specific tweaking to a model of monitor. You could get aberrations like ghosting because overdrive bounty isn't employed correctly to account for the VVblanking intervals.

Also, this should be really like shooting fish in a barrel to verify if this will work on a monitor. You lot only load up 1 of the many EDID reader programs. Y'all tin can see the header back up. Another thing I just thought of is that yous can brand your own .infs with many of these programs. If the VVBlanking header was nowadays, but disabled yous could just flip the bit to enabled by writing to a custom .inf. Adaptive-Sync for many!

Oh if I can get this working on my FW900 CRT I'll be happy

Also if this works on Geforce cards, amazing...

Definitely looks like Freesync works on non-FS branded LCD monitors based on Toasty X videos. Looks like FS branded monitors are tested for supported VRR range for EDID or monitor inf file and mayhap tuned overdrive settings like Despoiler says. I retrieve this also answers my question whether FS monitor had Freesync switch on a per game basis as sometimes Freesync would not enable when playing a game, clearly FS doesn't and AMD just assumes Freesync is on all the time on monitor side. If FS is non working on a particular game than probably outcome with AMD driver.

Already tried information technology did not work on my old LCD monitor, Freesync showed as "on" but still clear tearing on the red bar of AMD demo program, im calling this BS, yous NEED hardware support, thats the reason of why it took well over a year after annoucing it to get to the public.

It may work if someone has a new monitor with Freesync uniform controller that is disabled for comercial reasons.

Of grade you lot need hardware back up. But some displays not officially labeled as Free sync still comprise the needed hardware. And it doesn't have to be very new as it is all based on standards. But only way to know is to test.

Of course you need hardware support. But some displays not officially labeled every bit Free sync all the same contain the needed hardware. And it doesn't have to be very new as information technology is all based on standards. But only way to know is to test.

Actually it'southward not necessarily so much that some displays contain the necessary hardware without being labeled FreeSync compatible, rather it'southward the instance that some displays don't contain Freesync incompatible hardware.

ToastyX got this to work* on a Korean Catleap monitor, which doesn't accept any scaler at all, and since information technology doesn't accept a scaler information technology relies upon the scaler built in to the GPU. The scaler in the GPU is of course compatible with Freesync as long every bit the GPU is marketed as Freesync uniform.

*sort of, he had to apply single link DVI, so he couldn't run it at it's total resolution.

Interesting. I've got a QX2710 LED DVI-just. I'll keep an eye on this 1.

• #23

ToastyX has been a great help over the years for anyone trying to overclock the monitors, past the limits in the drivers. I use QNIX QX2710 at 112Hz daily, thank you to his CRU tool, and the pixel-clock patcher.

By the fashion, CRU for months has supported experimenting with Freesync range. You tin for instance, get an adaptive sync monitor like LG34UC88, which I recollect has a range of 42-75Hz, and then modify the lower range through CRU, to well-nigh 30Hz or so.

The new changes, seem to add HDMI extension blocks for DVI monitors (to trick the driver into allowing freesync), and every bit long as you stay in lower pixel clock range (250MHz) it works on some monitors. And aye, not having scaler on the display command lath helps a lot, even with just overclocking the monitor.

Finally, for VESA AdaptiveSync spec wise, the but change in the protocol (software) is that the monitor sends lower and higher sync range to the display card. Rest of the spec changes have to do with hardware compliance for the timing of adjusting refresh rates. Support of changing refresh rate itself on a frame by frame basis has been there for a while in the display interfaces.
