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

Notional · 12 Dec 2018 at 19:10

I thought they'd been manufacturing these panels since May. But it's still not launched in most european countries and we are under triple digits for large countries like the UK. Are LG having huge manufacturing issues?

No one knows but dont forget LG also sells panels to many other 3rd party monitor manufacturers so there is likely a large demand for the panels.

Please could an Nvidia GPU user with the 34GK950F confirm whether they are seeing severe stuttering at any refresh rate other than 144Hz? Using https://testufo.com/ghosting I see severe stuttering on my GTX 1080 Ti at any refresh rate other than 144Hz. It isn't just constrained to this test, but it demonstrates it well. Thanks!

Seems fine on all standard rates from 60Hz to 144Hz for me (1080Ti 417.35 drivers). Still get the random dimming though.

Thanks for confirming. I'll just put this down to a weird isolated quirk, some combination of my system and this being an early sample of the monitor. Haven't seen anybody else reporting issues like this and it's the first time I've seen this sort of behaviour on a monitor. At least 144Hz works properly though! Are you using Windows 10?

Regarding the dimming, make sure you've disabled 'DFC' in 'Picture Adjust' and disabled 'SMART ENERGY SAVING' in 'General' in the OSD.

Yeah I bet it’s the smart energy saving. It took me a while to figure out that as well when I first tested the screen and thought there was some weird dimming problem

Yes, using Windows 10.

OMG!! Thank you both for reminding me of that. I had set it off but then reset the monitor and forgot to set it back to off again. Pretty sure that's it as well

Setting changed so we'll see soon enough!

PCM2 · 14 Dec 2018 at 12:20

No problem, Bugbait. I think that will be the issue.

I've re-seated my GPU and for some reason the problem has disappeared. Utterly strange, but good!

Finally got mine yesterday, from a store in Germany. Its revision 00 manufacturing date: 2018/01/02 (thats whats written on the packaging at least). Colors, especially the reds were a lot more vibrant compared to my X34P, kinda reminded me of the reds on my Galaxy S9, which i quite like. Uniformity was also strong, but unfortunately the whole display was covered in smear, fingerprints and had two scratches oO. It had 2 dead pixels (tried pixel-fixes but of no avail), glow was a lot worse compared to both X34P i had before, reaching from the bottom right corner to the middle of the screen at 25 brightness and slightly tilted backwards to minimize the glow as good as possible. Overall very disappointing :/ .

Returned unit or could have been showcase unit that was then just sold to end customer (read: you).

Thats unusual i think - got mine from cyberport, it´s from may 2018 - you may see that on the back of the monitor
Just return it and get another one

Presumably the 950G does not have these options? I can't find them anywhere in the menu so I am guessing not.

I don't know what the hell LG is doing but i just received my second monitor today and yea.. This one is stuffed as well. The box is in perfect condition making me believe the monitor was already damaged even before it left the LG factory.

NirK · 20 Dec 2018 at 20:42

Wow, you have had 2 in a row that just arrived smashed? Really nice.

From the same store? Possibly more a courier damage issue if it’s the same courier bringing them to you?

ShadowR · 21 Dec 2018 at 08:21

Bought from 2 different stores but both stores buy from the same supplier. The LG rep just phoned me now to apologize and said i have seriously bad luck haha. Said he will have it replaced 1st thing in the new year as everyone closes today and currently there is no stock.

I will have to dream a little longer now for this display.

Cisco · 21 Dec 2018 at 13:24

Have mine coming. Fingers crossed no defects!

Gavin McGuire · 24 Dec 2018 at 18:41

@Daniel - LG any news on next shipment of monitors?
