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.

1080p is perfectly adequate for the most part unless you're a 4k photo/video editor maybe? The extra horizontal real estate is going to make a huge difference for me! Especially great for DiRT 4!
Exactly, this monitor is totally kickass for gamers with one card

Only if you have an 1080Ti or better. My 1080 non Ti is struggling big time with all newer games to push more than 60fps on 3440x1440.

Try playing om high instead of ultra or medium-high instead of high then. Almost as nice details and considerably higher framerates most of the time. Basically just turn off or lower anything that doesn't change much to your in-game experience. High and especially ultra are a bit pointless as they often turn on things that make barely any difference.

This is ironic. You can NOT take full advantage of these monitors, if you are having the best GPUs in the market because those GPUs do not like FreeSync.

Vega next month should fix that.

No "Normal" people buys a screen like this. 1440 in height and I think alot of people willing to through alot of money would be ready to move! I know I have friends waiting for this specific size (including myself)

I would like to see full review of both CHG70 and CH711, which was released last month. CH711 has VA panel, but CHG70 seems to have TN.

FreeSync 2 mandates LFC (basically 0- range)

You are also making things up, there is no 144fps monitor with adaptive range starting at 90fps.
Actually there is. My MG279 is 144 but the Freesync range is only 35-90

VA panels all-round and CHG90 has quantum dot leds. Not sure what exact panels the others have, although all seem to have 1ms response times. I think all have quantum dot (according to hardware.info), but that isn't the most reliable source always as the authors don't always check up on stories.

Im pretty sure that HDR is just tonemaping in game thats simply outputed to whatever screen is connected in format thats usually something close to 16-bit (24-bit) and sRGB.

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.

It's simply an array of tiny LED backlights with a LCD color filter panel in front. I do not know what defines a quantum LED, I think they're blurring the marketing line here. Not clear either, is if there is a LED per LCD pixel. If there was, I think the response time and contrast would/could be a lot better.

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)

1ms all-round apparently and 1ms is the lowest ratings go. How much faster must response time be?

Also it's Free Sync 2, not the original FS. With the release date at the same time as Vega, and also being Nvidia HDR certified, I think this is not that bad.

Vega will be a preferred option for this monitor, but yes, Ti is the card I had in mind when I said it. Besides, all the dreamers that complain this monitor is not 1440 need to remember that to retain the same aspect ratio with 1440 it needs to be over 5000 horizontal. I doubt they all have 1080ti in sli to drive it at 144hz.... And with 3840x1080 it will tax the gpu as much as 3440x1440.

When you are talking marketing, 1ms is not fast enough

Unless miners pick all of the stock like they are doing with Rx 470, 480, 570 and 580. Even used AMD cards have appreciated in value.

Maybe, but probably not. AMD might have mining cards soon which should keep miners from buying rx vega.

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.

If Samsung made a flat normal sized QLED monitors with these kind of specs they would be selling like hotcakes. Why TF is samsung pushing these curved monitors??

They might make sense on 49" and large monitors used exclusively for movies or games, but they make no sense as computer monitors. Screw you Samsung.
A curved screen is far more functional and practical on a pc monitor than it is on a TV in your living room.

Is a 4k Screen with These specs expected ? Somewhere down the line ?

16:9 soon, yes. 144hz 1ms qled 4k have been shown a while ago by multiple manufacturers.

To revive an old thread....

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.

I just bought C27HG70 too. Colors, contrast and black levels are really good. Only downside could be gray uniformity or dirty screen effect due to curving process, but it can be seen only in specific gray shades and doesn't bother me. Oh, and it costs over 600Eur around here. It's Firmware can be updated from USB Flash, it is a nice feature.
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.

I have since put the black equalizer back at 13, the default
