Acer X38 is basically their take on this. Same panel and all. We might see more contenders at CES 2020 in January. Hopefully to market faster than this one.

The things I would like to see is a decent HDR version of this and a model that offers PbP. I would not mind if Samsung jumped in the fray as well and made a VA model with this size/res. I'm happy with the display performance on my CRG9 so if they could get something similar to that it would be a pretty strong option.
The PbP features are very compelling, but I don't think we're going to see those on a Gsync monitor (the modules just don't seem to allow it) and personally, I prioritize Gsync over these "nice to have" features.

It wouldn't surprise me if we see a Freesync2 version, potentially with more input flexibility - again, that would be nice but I can live with 1 DP and 1 HDMI, I have a strong bias for the trouble free "just works, all the time" experience you get with Gsync.

Yeah I can see a FreeSync2 model coming next year. They’ll probably refresh the current 75Hz one. They already did once adding HDR, but DP 1.4 wasn’t really a thing yet back then.

You are probably right. I would not mind a FreeSync 2 version, I'm pretty happy with how it functions on my Samsung CRG9, meaning I haven't noticed any real difference compared to my previous G-Sync display but maybe I am not super sensitive to these things.

Keep your peepers peeled. Best Buy seems to get them in every other night, and Amazon has been getting them in stock every few days at around 1-2PM PST.

Well I’ve got it set up. Few frustrations but overall pretty happy. I think the form factor is pretty much perfect size wise. Perfect width without having to move my head.

First impressions, the stand is terrible, doesn’t go high enough, doesn’t pivot, no cable management. I’ll replace it with a Humanscale m8 over the holidays.

Picture quality is excellent, I’ll bring a colorimeter home to get it set it up properly.

IPS glow is there, it’s in the corners quite bad but as always it’s not unless you’ve got a fully black screen that it’s there. This side of OLED it’ll be fine.

Biggest frustration is probably the limitations of displayport 1.4. Turns out I only had 1 of like 6 display port cables that worked in higher modes. Best settings I can get with 10 bit color and HDR enabled is 120hz, bit lame but I knew . I’m hoping to replace with a HDR 1000 screen that can actually run at 175hz plus at some point in the future but let’s be real, it’s 18+ months

175hz is horrific for desktop use btw, the chromatic abberation around text is awful

Anyway, roll on ampere, need a gpu upgrade now for sure :)

Can you elaborate please? One of my biggest hopes for high-refresh was to make scrolling and general desktop use more comfortable, since I don’t game as often as I’d like to. I’ve heard two sides to this: people saying it makes a big difference and people saying it barely makes a difference. I’ve yet to hear someone say that it makes the desktop experience worse, much less a lot worse.

I tried to capture it but I was struggling, I'll set my tripod and proper camera up tomorrow to show it. 160hz is fine though btw. Just can't have 10 bit color. Which for 98% of stuff doesn't really matter (I say that owning a business that does a lot of visualisations)

175hz uses 4:2:2 mode, that has purple fringing around text. It’s fine in a game but for text it’s unusable.
This makes so much more sense. I know about chroma subsampling and it’s importance to text clarity, I didn’t realize you needed to drop it down for 175Hz (DP 2.0 and HDMI 2.1 cannot come soon enough)
can you not drop to 8-bit colour depth and maintain 4:4:4 chroma?
Same question I’ve got. I’d easily trade 10-bit for more frames.

Congrats. What settings can you change in sRGB mode? Does it have the RGB sliders available and maybe even CMYK sliders (colors like cyan, magenta and yellow) in sRGB mode?

Real shame DP holding things back. Can’t wait for DP2.0.
Everything just needs to go and stay HDMI. I'm sick of all the stupid arbitrary standards. AVRs are already HDMI so you might as well just go with that. It's too bad that even HDMI 2.1 is a little underpowered.

160 Hz is the highest for that afaik. Which is honestly fine because I doubt the panel even keeps up with 175 Hz.
Exactly that.

Not really sure what the right combo is, I did laugh at windows HDR awfulness (pdfs go dark) plus HDR is crap on the screen anyway plus I’m not gonna watch movies. 8 bit is probably fine given I don’t do visual stuff any more.

Realistically, for games, I’ve got a 1080Ti and 160hz is a pipe dream anyway so I’ll provably leave it on 10 bit and 120hz for now.

it’s annoying as fuck that the manual doesn’t explain the best combo of settings though.

No one can even see the difference between 144hz and 175hz anyway. It's too subtle.

You can notice 120hz -> 240hz, but 144 to 175 is almost nothing.

Can HDR be disabled on the monitor? The 34gk950f did not have the ability to disable HDR.

The OS defines it afaik, if it doesn’t receive a HDR signal then HDR shows as inactive. If you turn it on in windows then it shows it. There’s no “disable” option I can see but it might be badly labeled, manual is fuckin terrible.

I don’t really do anything video wise but if I get some time I’ll play around with it. Unfortunately I have shitty broadband so I’m not sure how but I’ll work it out.

So whats the highest refresh we can go on this monitor without losing colour for SDR games?

160Hz 4:4:4?

What about 8bit color?
Is it 160hz 4:4:4?

And 10bit colour is only needed for HDR is that correct?

Or does 10bit color add something to SDR aswell?

Some graphics and visualisation things use 10 bit, but it’s one of those “don’t need it if you don’t know you do” things.

So it’s pretty much HDR, which is shit for this brightness. So it’s no great loss. If you wanted it in a game I’d just lower the refresh for that game.

I think we’re a couple of years away from having a good combination of image quality, resolution, HDR and refresh rate, but I guess we’ll see after CES. Kinda hope I’m wrong but I also don’t want to explain another purchase this time next year

This is almost there, PG35VQ is almost there with different compromises. It’ll keep evolving until we get to 10K nit, 8k, vrr with emissive screens or micro led. It’s just finding your sweet spot.

The prices can fuck off though. It’s madness, Even when you can afford it. Then again, I had an lcd back when they were thousands so it’s not the first time. Hopefully there is a downturn at some point so manufacturers stop cranking the price handle on consumer electronics for nominal improvements.

HDMI is royalty-ridden, so there will always be a place for DisplayPort. DP is also more flexible, too, with Thunderbolt / USB-C integration.

HDMI exists separately because of the MPAA and their need for control. And HDMI technology has always been a ripoff of DVI and now DP :/

I agree with that BUT the bottom line is that AVRs don't support display port, so it's ultimately useless.

We need seamless computer -> AVR integration.

Eh, I'd more support a hard delineation between the two. HDMI support on the desktop / computer space in general is a bit of a necessary evil. DisplayPort may not always be superior in lock-step, but it's likely to be the better transport most of the time. It's certainly more flexible today if you're pushing the limits, like needing to bond outputs for a single higher data rate display like 8k60 or some such.

As much as I agree with the sentiment, and I do believe we'll get there eventually, external interests (MPAA) are going to force the industry to take the long way around.

Fortunately, since HDMI moved from DVI signalling with version one to DP-like packet streams with HDMI 2, it's likely everything will devolve into USB4, i.e. Thunderbolt. If we get 'one connector to rule them all' in the next decade, that will be the one.

I'm okay with anything as long it lets people do what they want to do. The HDMI audio/DP video frankenstein mess is getting really old.

Well, they're both holding the industry back at this moment. Neither is up to spec as to what displays can actually do.

Is any one using the variable backlight feature, this is the first monitor that I have with this feature and wondering what the best setting is for it or if its even worth using. So far very happy with monitor, just waiting to install the ergotron HX stand.
Thanks

Hey man, can you check if RGB controls are available in sRGB mode?

From TFTcentral:

Very little info about these two at the moment but LG are also showcasing at CES their new 34" 34GN850 (HDR 400 only) and 37.5" 38GN950 (HDR 600). Both have 1ms Nano IPS panels and 160Hz overclocked refresh rate, but that's about all we have. Let us know if you see any more info!
I’d guess 38GN950 might be the FreeSync equivalent of this.

Now we can only hope it doesn’t take another year to get those out and the cost is lower.
Indeed. This is exactly the sort of (reasonable) thing I’ve been waiting for, and it’s finally within sight. I think I should be returning the LG 5K I bought a few days ago after growing sick of waiting.

The thing is, the G-Sync version is going to be better because of variable overdrive. Once you're spending over a grand for a monitor, I'm not quibbling over a couple hundred bucks here and there.

The thing about CES is that anything they show or talk about it we wont actually be able to buy until Fall at the earliest and often that's being generous on the time line. Meaning a whole year or two after. All we can do though is hope and wait.

g-sync is much more effective than freesync. once you play on a 120hz g-sync display it is very hard to go back to a normal display. The dedicated hardware module syncronyzes frames with gpu too effictively. They say oleds don't need g-sync because the pixel response it too fast but I highly doubt that statement.
