Never heard of any new firmware for these LG monitors. Even if there is one it often means having a monitor serviced to get it updated. It's rather rare to get an updater to download from manufacturer.
Yeah some of the AUO VA variants are curved, eh.
PX329 is flat. LG are flat. But Acer and BenQ have the curved variant.
I won't use curved monitor after trying a couple of the curved Samsung VAs in 27" and 31.5", it's simply wrong and distorted as expected, the panel quality is often ruined by the curving process too and all it seems to offer are disadvantages and undesirable characteristics. Why do they curve most of their VA monitor panels? To help deal with the poor VA viewing angles a little, to "look cool" in marketing.
If you like the VA options, I would stick with flat AUO or try the newer flat Samsung options but I don't those models or what is there finally available with them.
There is stuff like the 38" UW from LG but again most UWs are curved = undesirable and insanely priced, https://www.tftcentral.co.uk/reviews/lg_38gl950g.htm
and it has the same issue as other newer LG IPS "gaming" panels, damn low contrast for an IPS, below 1000:1 in a territory of old TNs. For that price, it should have had at least FALD if they can't do dual layer.
For UWs there is now https://www.tftcentral.co.uk/reviews..._nx-edg34s.htm
which I've seen getting mentioned lately. Again, to me undesirably curved, has a blacks smearing Samsung VA. But it's around 500-700 USD/EUR which is a bit lower than the insanity of other UW monitors at 900-infinity.
Why do I hate curving? It distorts the image, the image from 3D apps/games is rendered centered camera looking at a flat plane, not looking at a curved plane. All the speed perception in games is wrong due to it. You can adapt, somewhat, if you can sit very still in the same spot but it's annoying and less consistent than using a flat screen. All the webpages, movies, etc. are gonna be warped.
But also because you get crap like this because of it:
^ASUS TUF VG32VQ from rtings
Though right up top in search of this ASUS is an YT video of how bad it is when it comes to Async+strobing, the language is so bad I would get a warning on OCN for even writing it's title.
Yeah, don't fall into the strobing deep hole, strobing is great to reduce motion blur of sample and hold by strobing instead but it needs to be user adjustable or damn right perfectly done by manufacturer otherwise it results in endless crosstalk between frames. Let alone with Async it also has to keep the perceived brightness equal for each frame. The idea and technically it's simple but it has not been sold working well so far. There are some older BenQ/Zowie monitors with an official 3rd party app to adjust the strobing but those are the only I know that could actually have a usable and adjustable strobing.
Sadly all the 32" 1440p 144+Hz are VA so far.
I have no hopes for LG ever resolving any issues with their products. You can talk to them, somewhat with some luck but you will never get any firmware update out of them (I tried, others tried), as always they will tell you to send it in for servicing and that won't solve anything if they have no firmware update to fix the problems. The 850G had not only sharpness issues but also unwanted OSD popup. Early batches looked nicer than older batches where people started to get defective panels. Or mine where the electronics were loose somewhere inside causing problems with connection quality and artifacts on half the screen most of the time. All this with 2 years (law minimum, probably 1 year in US etc.) only warranty on probably all LG products = low confidence in their own products lasting, doesn't matter if it's a 500 EUR LG monitor or 2500 EUR LG TV, you're gonna get 2 years warranty, it's nuts. Other manufacturers offer longer warranty even on way cheaper products.
If you like VA, there are options, flat and curved, but very limited options to AUO or Samsung VA in 100+Hz.
For other LCD types, so far nothing in 100+Hz
Soon, maybe, who knows, check TFTC's blog/log of when what panels should arrive.
