AMD Shows First Displays with FreeSync Support
AMD announced a competitive and affordable solution to tackle Nvidia's Gsync, it goes under the name FreeSync also known as Adaptive Sync. AMD right now is demonstrating desktop monitors and no longer laptops supporting the technology. Freesync will make the monitor dynamic as well. G-Sync and FreeSync will get rid of screen tearing and tiny sync stuttering/pulsing.
The protocol FreeSync / Adaptive Sync will be embedded into DisplayPort 1.2a and eDP (embedded Displayport), there is a catch though, manufacturers of monitors are free to decide wether or not to support the technology. At Computex there are supported monitors on display, AMD however will not reveal the manufacturers just yet. The Video Electronics Standards Association (VESA) already announced the addition of 'Adaptive-Sync' to its popular DisplayPort 1.2a video interface standard. So you guys know, Nvidia does more or less the same thing, yet it requires a 200 USD module to be embedded into a compatible monitor.
AMD claims that as long as the manufacturer will stick to the Displayport 1.2a standard it will support FreeSYnc/ Adaptive Sync and as such that would be free. We do have some reservations about that statement as the monitor definitely needs to be compatible with the standard, and that requires R&D and the right hardware scaler to back that up. That or AMDs implementation could add additional CPU overhead to do a lot of stuff on the software side of things. We are not sure yet as to how that will pan out.
If you like to learn more about the 'overall' technology, have a peek at our G-Sync article. Both companies use different methodologies, but the outcome is nearly similar. FreeSync / Adaptice Sync monitors will be available in Q4 of this year. The photo is courtesy of Tweakers.net (see source link).

I bet nvidia won't use this technology simply because they're too proud of Gsync, they may even add a new feature (ie, gimmick) and use that to justify the existence of Gsync.
Another thing is the cost. Gsync was never cheap to begin with and now looks like a complete rip off next to FreeSync. I doubt nvidia will have enough time to cover the cost bringing this thing (Gsync) to market.
edit: But kudos to nvidia for actually looking at how to fix screen tearing and coming up with a solution, even though it cost as much as a single entry level GPU.
Nvidia's solution is expensive because it uses an FPGA instead of an ASIC chip which is significantly cheaper. They did this so they can deliver firmware updates to in the future. They already talked about removing polling and other things to help reduce latency and performance impact. It's also possible they can come up with some other neat tricks via firmware.

Monitor on left is already existing monitor which is 60Hz but was made with HW capable to pull that stuff so they did just FW update.
On YT video I noticed that this FreeSync screen had built in webcam at top center.
I guess it may be bit hard to find what screen it is based on this an other physical features, but not impossible.
Another thing what Guy stated in video is: Freesync can go from 9 to 240Hz ATM.
Edit: Based on external power brick and stand it is Nexeus.
On some pictures one can see description for buttons to bottom right, but none are clear enough to get language they are in to confirm exact model.
Edit2: Found him:
NX-VUE27D - 2560x1440 S-IPS (eBay/newegg ~= 400$)

It doesn't have to be purely software upgrade.
I can remember NV showcasing G-Sync with ASUS 32" 4k monitor, which was hacked, with a gaping hole at the rear, cables and PCBs sticking out.

The FreeSync Off monitor is completely different. They could have used a really crap monitor for that instead...
Bad comparison is bad!
Yep.
I personally wont be bothering with a new monitor untill 2020 or so, since i bought my current EIZO CX240 not long ago.
The bad monitor that you are talking about look to be the 27" Asus. certainly the PB278 PLS ..
Anyway it dont affect freesync as it is not the purpose of it.
Dave Baumann:
The demo was a full "FreeSync" demo, i.e. controlled variable refresh rate. DisplayPort ActiveSync is not, however, FreeSync, it is purely part of the ecosystem specification that enables FreeSync to work. FreeSync uses the specification and GPU hardware and software to sync the refresh rates.
During display initialisation the monitor EDID will send back the timing ranges available on the monitor to the GPU and the GPU drivers will store these for operation and control over when to send the VBLANK signal. During a game the GPU will send a VBLANK signal when a frame is rendered and ready to be displayed; if a frame rendering is taking longer than the lowest refresh then the prior frame will be resent only to be updated with the new frame as soon as it is finished within the timing range.
