ahhh mister tft central himself :) i love all your reviews and i have been waiting for ages for a 21:9 with no inputlag / signal processing time. ( i love the measurement and numbers you put into the reviews ) to bad there where no ufo trailing shots for the lg review. is it better or the same as the others in its class?

yes it's very comparable with the other high refresh rate ultrawide IPS models in terms of motion clarity.

i don't see anything about the panel bits on the official lg site in the specs list. but i might overlooked it.

yes, as linked by another user, it confirms 8-bit in there specifically

So yes the 34GK950G is only 8 bit, is this purely limited because of the g sync module ? or purely a choice by lg to only have 8 bit on the 34GK950G.
Because of the asus pg348q has 8 bit + frc. maybe thats the reason why its a bit slower than the new LG? (inputlag / signal processing time)

the 8-bit limitation i believe is related to the bandwidth limits of DisplayPort 1.2 here. For the Asus PG348Q at 100Hz it is possible to achieve 10-bit, but i believe 120Hz is pushing it too far and so 8-bit was the limit. Similar on the Dell Alienware AW3418DW which is 8-bit. The additional lag of the F model is related to the internal electronics and scaler, which is fairly typical for any screen (the 9.8ms of signal processing lag isn't super-high), whereas the G model doesn't have that to accommodate the G-sync module, and so has basically no signal processing lag. Again that's very common on G-sync screens

Can someone explain to me exactly what the heck “black stabilizer” does in real monitor terms, not in marketing speak? Does it increase local contrast or gamma by some algorithm? Does it destroy picture quality and shadows?
Was not clear from the TFT review

it tweaks the gamma curve of the display to help make it higher in darker content, without impacting the brighter areas too much. So it's different to changing the overall gamma control, it just tweaks it at the darker end. so it helps to bring out details in darker content and games if you want

sorry for the slow reply, i hadn't seen your response. If you're going to be able to reliably push high frame rates from your system, at the settings you play at, then variable refresh rate becomes less important. However, i still think it has enough benefits to make it logical to select a G-sync screen here if you're an NVIDIA user personally. The 950G is a very good screen and should perform well. i think the only significant consideration left is whether you want a wide gamut screen (950G) or a standard sRGB screen (X34P or AW3418DW) and how much money you're willing to spend. The acer and Dell models are a little cheaper, but they will only offer standard colour gamut. it depends if you like the accentuated, more vivid colours that a wide gamut screen can offer, or would rather have more accurate colours for normal content

Wonderful! Thank you so much :)

I hope AMD gets back in the top GPU segment as i don't mind using an AMD card at all only reason i got Nvidia now is because the price of my card was really good.

Hello to all members. Been reading this forum and can ressist to not to join it. Just wandering how to be sure that this new monitor is with new panel(144hz downclocked)? And not old panel(100hz overclocked)?

You could probably dismantle it to find the part number of the new panel inside... but that's not likely to be a good idea unless you want to void your warranty.

i've already saved you the trouble and done that, and confirmed it's the UW5 panel - you can also be sure of this because it's a wide gamut screen and the older 100Hz overclockable IPS panels were sRGB only

I may take it apart anyway, as I hear they got fan on the back so it may good Idea to put some liquid metal there ??

there's no fan cooling on the LG 34GK950 models

Thanks for the info, no fan and new panels is OK. Just when for heck sake we be able to buy in UK? Daniel LG said it should be in OC website today, if I understand correctly.
 
Full Array Local Dimming FALD monitors like
Asus ROG Swift PG27UQ
Have fans possibly the monitor you were confusing this one with
This one has passive cooling
The Asus ROG Swift PG27UQ has an extremely cheap and very noisy fan at that. I sent one back as it was mis-reported by many reviews as silent which it is in no way silent
This panel on the LG is under-clocked from 144Hz to 120Hz on the G sync model
 
One more question for @Baddass does the low latency only work when you run in gsync ? or is it also the same if you run no sync at all? or anyone else who knows :)

i am asking this because i like the feeling of 200 fps locked or unlocked now @ my old 1080p 120hz screen with no sync at all.

I'll field that question. G-SYNC is not active when running an input lag test using a utility like SMTT 2.0. So the latency values given are independent of G-SYNC.
