LG 34GK950G, 3440x1440, G-Sync, 120Hz

This monitor seem to become such a waste of potential and I guess Nvidia is to blame? Imagine this monitor with G-Sync and 144Hz on the new panel. I guess the lack of HDR10 was the reason they were not allowed to use the new GSync module?

Honestly, I wish they could have skipped the HDR and just realeased a awesome display without HDR10. Oh well, I guess the F-model still has the new panel or just go with the DW for a much cheaper price.

Did they realised no one would buy the monitor for the asked price with the new panel but same Hz so to lower the price they went with the old panel? Going from being close to something groundbreaking to basically nothing new. This is a belly flop. Sorry for the rant I am just disappointed. If this is true that is. (Sorry for the bad English, I am from Sweden.)

This monitor has had a nightmare journey and still hasn't made it to market yet! I trust Daniel when he says that the panel will be the new UW5, but that begs the question why the marketing and website show 120Hz overclocked; and if it still uses the UW4 then it is about 9 months late to market!

The new Gsync module is too expensive for this model... given the price of the new Gsync module, I would expect higher than 144Hz, which is the limit of the UW5 panel.

Someone on reddit said DP1.2 can't run 120hz fluidly so it needs to use chroma compression to achieve that (which is why its advertised as 120hz overclock). I don't know much about bandwidth and chroma compression so Im not sure what this all means and whether there is legitimacy to his statement.
 
Anyway we can get confirmations on the final pricing of the 950G and 950F? I read earlier about talks of bringing these panels to competitive pricing with the X34P/AW models, but I'm now seeing those regularly go on sale for sub 900.

I think this is trash. The Acer and Alienware hold a solid 120Hz over DP1.2, so the bandwidth is there. The bandwidth is there at 120Hz, but not 144Hz, which is why the UW5 panel would be run at 120Hz despite being capable of 144Hz. The Freesync model will use DP1.4, and will therefore run at 144Hz.
 
Personally more interested in the freesync version anyway, not bothered about gsync despite being on Nvidia for the foreseeable future. Seems like the much better panel spec wise.

Getting LG to actually release the freesync version of the display is incredible frustrating though, they seem to drag the release well after the gsync versions are out.. Can't even get the freesync version of the 32" VA yet either.
 
The people on reddit are getting the pitchforks out! No one there is happy at this development. @Daniel - LG can you please confirm if the 120hz is native or OC. I know you said earlier that it was native, but those new listings have it as OC, with 400cd/m2 brightness (so im assuming its the latest updated spec sheet)

@Stu

The guy is correct it drops to 4:2:2, which is not that good for computer games as it crunches the colours.
Why? Simple maths. DP1.2 has maximum bandwidth of 17.28Gbit/s

3440x1440 100hz 8bit comes to 14.86Gbit/s
3440x1440 120hz 8bit comes to 17.82Gbit/s
3440x1440 144hz 8bit comes to 21.39Gbit/s

DP1.4 on the other hand goes to 25.92Gbit/s data to push even higher to 165hz without issue.


Also the difference between 4:4:4 and 4:2:2 can be seen here

Looks like I might have to go the freesync route and the 950F if I want to enjoy anything over 100hz without compression.

Tbf it does seem like a v v good solution. Not hampered by the current Gsync failings either, hardware costs are only going to scale in the wrong direction. Wouldn't surprise me that either nV will go software-only (ala Freesync, a $500+ module just seems crazier and crazier once you think about it!) or a full support of Freesync/Adaptive Sync soon. Hoping it's the latter personally :)
 
The 3440 x 1440 monitors which run at 120Hz do not use any chroma subsampling or other such compression. I've recently tested the AOC AG352UCG6 and it supported the correct Full RGB (which is 4:4:4 Chroma) signal without issue. The Acer X35P is similar. Don't fall into the 'maths trap'. There is actually a bit of leeway with bandwidth, it isn't as rigid as people here are making out which as why such nonsenese is being spouted.

For educational purposes, how did you go about testing this? I'd like to familiarize myself with the process.

If you open Nvidia Control Panel and go to 'Change resolution' it will tell you which colour signal is being used. You can even try to enforce another (including 4:2:2) and see the difference yourself, depending on the screen you're using.

4:2:2 is easy to distinguish from 4:4:4 on the desktop in particular. Narrow edges such as text will often appear fringed, more noticeable on some text and background colour combinations than others. A test for this - http://i.rtings.com/images/test-materials/2017/chroma-444.png.
 
I am not really interested in all of this refresh rate drama because it is not practical anyway, but if there is no native 120 Hz and no HDR then what does this display have to justify such a high price? AW3418DW is much cheaper, 25% to be exact, and has very similar spec because 99% of DCI-P3 coverage by 950G is meaningless if it has no HDR support. And with Dell you get 3 years of serious warranty instead of 2 years of pseudo one, at this price point anything less than door to door is a disrespect. Alienware looks terrible, I'd rather not get something like that onto my desk, while LG is like the only mainstream desktop display manufacturer right now that can do good looking product (I mean just the display, stand is not needed), but the price difference is too big just for that. The only thing left is UW5 panel and Nano Cell. The quality jump from UW2 panel (Acer X34, Asus PG348Q, Dell U3415W) to UW3 (LG 34UC88/98, Dell U3417W) or UW4 (AW3418DW) was massive and game changing, while Nano Cell is a Quantum Dot so it will be good for the eyes, but the question is will it all translate to any kind of significant improvement over UW3/UW4 in real world use.

If there was any 38" 3840x1600 with G-sync then I would just get it and be done, but as always there are huge compromises to be made and you cannot get all in one. If you can even talk about "all" with basic LED LCD panel with no dimming or HDR in almost 2019...

I don't know, all the these displays do not feel like enough of an upgrade from my 2,5 year old LG 34UC98. It developed some stuck pixels after 2 years, quite a lot actually, but aside from that is has all qualities it had 2 years ago and there is still nothing better in terms of picture quality. I have tested Samsung CF791 few months ago and despite Quantum Dot and factory calibration it was nowhere near the LG, performance in dark scenes was marginally better (to be expected, whether it is 1000:1 or 2500:1 contrast, it is still terrible) while everything else was very significantly in favor of LG IPS.

I will probably wait for 950G to get to proper price and then I will test it against UC98 and see if there are any improvements in picture quality. There is nowhere to rush if there are no major upgrades available on the market anyway. I will test it when it gets down to current Alienware price.
 
At this point the only reason I am holding out is because of the Alienwares lack of gamma controls and the fact that most people are getting to only as low as 2.4 gamma with OSD calibrations. Im very OCD about having my monitor as close to ideal calibration through OSD adjustments alone and 2.4 gamma is a significant deviation.

Then again is it worth the difference in price? will the LG have the standard first panel revision issues? how long is too long to wait?
