Samsung Announces the CHG70 and CHG90 QLED Monitors: HDR and FreeSync 2
Remember that post on Samsung's investment on 32:9 aspect ratio monitors? The company has just materialized them, with the announcement of their 2017 flagship FreeSync 2 supporting monitors, which come in two different models and three different sizes. Samsung announced a world's first, the CHG90 QLED monitor, which leverages its alien 49" towards displaying a 32:9 presentation. That's what Samsung is calling a DFHD (Dual Full HD) screen, with a 3840x1080 resolution. This panel supports FreeSync 2, HDR, wide 178-degree viewing angles, and the now usual 1800R curvature, with blazingly-fast 144 Hz refresh rates and 1 ms response times.
At the same time, Samsung also announced the somewhat more mundane CHG70 QLED monitor, which comes in at either 27" or 31,5". Whatever your choice of panel size, these are essentially the same specs-wise, and differ little from the CHG90: they offer WQHD resolution (2560x1440), HDR, FreeSync 2, wide 178-degree viewing angles, and the now usual 1800R curvature, along with blazing-fast 144 Hz refresh rates and 1 ms response times.
Connectivity-wise, the CHG70 models sport 1x DisplayPort and 2x HDMI inputs, and the CHG90s adds 1x mini-DisplayPort interface.
But what exactly does FreeSync 2 do? Basically, it stands as a way to reduce input lag from HDR processing of an image, by substituting the entirety of the HDR transport and display tone mapping usually needed to render a HDR image by a faster, driver level, Freesync 2 transport (which apparently already includes display tone mapping before the image is sent to the monitor), thus reducing that tone mapping processing time. Another part of the Freesync 2 update is the ability to instantly switch between display modes (SDR and HDR). AMD is also touting Freesync 2 to display "over 2x perceivable brightness and color volume over sRGB", though that honestly looks like more of a byproduct of using an HDR source than a Freesync 2 achievement. It looks as if FreeSync 2 will eventually become a software stack, and a brand, unto itself, embedded within AMD's drivers and other, non-PC products. This would be a smart move from AMD, since they would be taking advantage of FreeSync's brand and name recognition on the market as a way to promote new features.
But let's go back to the DFHD, 49", 3840x1080 CHG90. This is the new way to have your field of vision almost as filled with screen real estate as when wearing one of those pesky VR headsets. But one has to consider: 21:9 support by itself isn't guaranteed fully as is, and there are many more panels featuring that display ratio than a single panel. What should we expect will happen with 32:9 ratio monitors? Will developers truly consider such a meager proportion of their audience?
On to pricing, which is arguably the most important metric: the C49HG90 is available for pre-order for $1,500 (which doesn't seem all that steep for such technologies?) The C32HG70 is exclusive to Newegg for $700 (at least for the moment), and the C27HG70 can be pre-ordered from Samsung's website for $600.

Otherwise we wouldnt have such nice banding issues in most games when you look up at clear sky (unless you have like ReShade with dithering/debanding effect).
In short, it looks like marketing BS to me and as far as I have seen many LCDs they usually barely fit sRGB colorspace. Not mentioning about hue and color balance which is mostly crap.
Not to diminish what is probably a great product, I'd consider buying one if there wasn't much better technology on the immediate horizon (hint, the word organic is in it lol)
Better price/compute power maybe, but I just don't see miners buying vega. Otherwise 1080 ti's would be used all the time for mining, but they aren't and vega should have similar or maybe slightly better price per tflop, tflops and price but higher power usage making it a just as viable option and I've never heard of 1080 ti mining setups.
And how to unlock full range:

The CHG70 is amazing. I picked up a 27" C27HG70 on black friday for $450 and it greatly exceeds expectations in every way. It's an entire league above my plain old 60Hz 1080p IPS. Color, contrast, response time, smoothness/fps, HDR, everything. Runs amazing on my nvidia gpu, I just enabled adaptive sync in the nvidia control panel and I'm not seeing any tearing. No freesync/gsync required.
The calibration from rtings.com seems to work but I'm not sure this thing even really needs it. Looks great out of the box with the black equalizer off / at 20.
:rockout::toast:
It is great going from faulty by design Benq XL2430T to this. Black equalizer feature amongst other things on Samsung is actually useable, in comparison to BenQ's version.
Overall I am happy with it.
