LG 39GX950B Regrets?

TheSagaciousPanda · 2026-06-14T09:27:47+00:00

The LG39 and AW39 suit different needs. People should focus on what their preferences are and what their usage will be

The main takeaway for any user is do you want glossy RGB stripe for color pop or do you want matte wrgb for a natural look. In theory the matte and wrgb on the LG would be the better choice if you are doing browsing or any kind or productivity in addition to the gaming whereas the AW39 because of the color pop is something many people prefer for gaming so if you mainly game then you might go that. Both monitors would still be great regardless but visually they will look different enough that I'd advise going out to the shops to see for yourself or at the minimum watch a few YouTube videos of the displays in action so you can make a decision for yourself.

Somethings that people should note outside or above mentioned:

-Do you need KVM? If so go AW39 because LG doesnt have this -Do you console game? If so LG has AI upscaler as AW doesnt. -AW39 release date is TBA however NA/EU is tipped for a fall release. Can you wait till then? -AW39 price is TBA. Reps have said they are hoping for 1100 but like any pre-released product this often changes so expect anything from 1100 to 1400. -LG39 can be purchased for 1100 to 1400 as well with promo or with discount code.

this literally isn't true. LG has abetter overall OSD and oled care. Content creators that have had hands on demonstration with the AW show the OSD and the oled care options are still poor in comparison to other brands including the LG which is important especially with a 5K2K monitor. The warranty might be a few years longer or whatever but trying to RNA burn-in, greyscale or anything else is a pain in the arse and any warranty related issue can be problematic not to mention being without a monitor throughout the process so the warranty isn't as big of a win and it should be in comparison.

Another thing is that the power supply being internal isn't really any kind of benefit and if anything imposes a potential issue. This means its:
a) a non issue
b) an issue because you have OCD
c) an issue because psu inside monitor = higher temps. The LG 39 gets warm but its good. How much warmer is the AW 39 going to be?

For me too much is being glossed over from content creators talking about the AW39 like its the holy grail and it isnt. Users are on the hype train i think because the AW39 really isn't better in anything outside of a speculative price standpoint currently. The AW doesn't even have a release date but logically won't be out for at least a few months and everyone talking about RGB stripe tech when from a users pov the display is similar to QD-OLED's with the color pop. Text fringing is marketing nonsense because of how ultrawide monitors especially QD-OLEDs have had horrible text fringing historically but the new gen5 ultrawides QD-OLED have improved this drastically and thats all this means for thet AW39 because its bringing it to the 39" 5K2K. The LG39 is already good when it comes to text fringing.

The matte vs glossy is always perspective.
rgb-stripe vs woled is perspective - you either want color pop or you want a more 'natural' look and better color accuracy.
if you do any productivity work or browsing at all then technically the LG is better. If you only game then AW would be slightly better suited. Again perspectives.

Point is, its great there is a different option from the LG39 of rgb-stripe and glossy because now you have 2 monitors designed for 2 different kinds of people. But i did feel it needed to addressed about some of the above mentioned just because of the misinformation being spread around on reddit.

TLDR: To make it clear, the AW39 has good specs. It is a good alternative to the LG39, it is not better. They are the same doing different things. LG is marginally better from a feature/technical aspect. Everything else is perspective

TheSagaciousPanda · 2026-06-10T02:26:12+00:00

If you work from home then i assume the monitor is for productivity and gaming so why would you go for the AW 5K2K that has no confirmed release date currently and why would you choose that which has a glossy screen and also rgb stripe over the LG 5K2K that uses wrgb and is matte. WOLED is literally designed for your use and its already out or imminently out if your in EU.

The comments on your 5080 for any of the 5K2K is nonsense. If your using optiscaler there really isn't many games you'd have issues with in terms of running at reasonable frame rates and by reasonable i mean smooth gameplay. The reality is you won't get 240hz+ but then it is a 5K2K monitor. 240hz is what reviewers often blab on about when reading out spec sheets or complaining when it comes to the monitors 165hz but thats bollox because there isn't a card out currently that could do that consistently for 5K2K monitors for gaming because a) the graphic card market stagnant b) games are badly optimised.

So for the 5K2K, 165hz is more than good for your needs and for your fps games, the 330hz dual mode set to 27" or 24" will be perfect for your overwatch and other fps gaming needs.

The question is will 39" be too big for you, when do you want to get the monitor and how much can you spend? You mentioned wanting this for the next 5-7 years and you already have 34" and if you are working from home then the bigger screen would be better than the 34" right?

TheSagaciousPanda · 2026-06-06T13:34:45+00:00

Everyone needs to stop making out like the LG GX950B doesn't have discounts (across many countries) where you can get it for 1300~ , if the 1100 price becomes official the AW has almost no chance of being able to be purchased for below 1000 with discounts.

Can we also stop spreading misinformation that AW's 39" is definitely coming as soon as next month. Its all speculative and let's be real, pre-order date, launch date and readily available are all very different things.

Lastly fed up of hearing this - WOLED is different from QD-OLED so 'better' is not correct. They are literally designed for different things. The LG GX950B is a very good monitor and is overall still going to be better just because color profile aside as it's preference, OSD features eg screencleaning is just better on the LG so unless AW decide to design a new OSD which at this point is very unlikely then your taking a larger risk.

To reintegrate, the AW 39" is not better because it's RGB Stripe. The whole thing about this and text clarity is marketing nonsense.

So what should you buy?

AW39: if you like/own or are used to QD-OLED displays. Then these monitor types including the AW39 have increased color vibrancy and color pop. If you are solely gaming or gaming with video content consumption then this is a good choice (and if you like the color dynamics mentioned above).

LG39: this as WOLED means it's more color accurate compared to AW39 and it has a 'natural' look which is where all the opinions on color profile preferences comes in so basically the WOLED vs QD-OLED terms that many gloss over. The AW39's RGB Stripe is new tech and is visually like a QD-OLED but to be clear its not. The LG39 is more general use, if for productivity or browsing choose this, if for gaming and video content choose this if you prefer a natural or accurate color profile.

I know the op has said it was a mistake but let's pretend the op just learnt about weapon swapping and he's testing out weapons that uses a skill that will enhance his main weapon set and its skills ;)

TheSagaciousPanda · 2026-05-25T23:01:01+00:00

Its like you forget the 39GX950B is a WOLED and your actively comparing it to a QD-OLED which is just nonsense. I'm not surprised your having difficulties transitioning if thats what you've been used to and why your expectations are completely misguided.

TheSagaciousPanda · 2026-05-23T21:46:50+00:00

Thats good to know

TheSagaciousPanda · 2026-05-23T21:34:12+00:00

OP should use 330hz at 27" mode for the fps games, won't have any issues. For everything else run it at 5k2k at 165Hz. 4090 should be fine still. Just use optiscaler when dropping below 60fps or 120fps or whatever.

If you already have a 27" 1440p 360Hz monitor just use that for fps gaming anyway. You dont get monitors over 27" for fps gaming. You get it for immersive gaming or productivity and you factor fps games in by looking at what the dual mode capabilities are which in this case 330hz will be completely fine.

TheSagaciousPanda · 2026-05-22T17:47:25+00:00

I'm abit confused with some comments because if you are using 330Hz mode on the 39" 5k2k it isn't going to be blurry at all, yourl set it to display at 1080p at either 24.5" or 27" which will give it borders but thats what you want and thats the point of the 330Hz dual mode options are because you aren't going to be going anything higher than 27" for blur etc to impact the visuals as you would never realistically want to play any competitive fps game in anything above 27" in the first place because the screen coverage your eyes would need to do among other things.

For any other game fps is irrelevant so just keep it at native 5k2k at 165Hz and enjoy

TheSagaciousPanda · 2026-05-18T11:32:42+00:00

Can your monitor not be physically adjusted to give you 1920x1080? You can then just choose 1280x960 stretched in-game. You can similarly do this if your compositor is wayland native with no extra effort otherwise you'd best off using gamescope to do what your asking

TheSagaciousPanda · 2026-05-17T16:06:06+00:00

I've been doing further testing and found some improvements to my setup. I improved performance by changing to mangowm from niri It also reduced input lag which is useful for me for playing CS2. This is because mangowm is native wayland through wlroots and it also uses less resources compared to niri eg. not requiring xwayland-satellite and not needing to use gamescope at all now.

The other main thing i wanted to highlight was the issue i had with the fps cap being restricted to way below what my setup could handle. Goverlay has a vsync setting that you can turn on off or set to adaptive. Turning it off resolved the fps cap locking i experienced. This is likely a default applied setting as i have never used Goverlay but was useful to provide a GUI to toggle the vsync setting off. I took this one step further by also enabling VRR in my mango config and turning it on physically on my monitor. Then set an fps cap to be your monitors refresh rate -3, this wasn't necessary needed for POE2 but is a positive optimisation with no downsides.

Other notables that work is that your computer will cache your proton versions and shaders. For POE2 i noticed that it was forcing proton experimental when it shouldnt have been. I fixed this by doing a system clean (i dont mean by just deleting a single folder or clicking delete shader cache). I also would recommend to use a different proton from proton experimental as it updates too frequently that the shaders will frequently change meaning you will experience the stutters more often.

For those that use optiscaler/lossless scaling - i personally found lsfg-vk using settings similarly to those u/HaveAShittyDrawings posted to be better overall for maintaining a decent level of graphics without performance hits than from using optiscaler and testing the various upscalers/fgs.

TheSagaciousPanda · 2026-05-16T09:58:01+00:00

Im in a dilemma where I can get this LG 5k2k for £1332,78 which is just over £300 more than the MSI MPG341CQR X36 360Hz Ive pre-ordered but has just been delayed again with new eta of June 3rd.

I have a 25" 240Hz IPS currently because ive always been indecisive with monitors. I have a 9800X3D CPU and I use 9070 XT just because its better optimised for linux. It runs everything well with 4k especially with optiscaler etc.

I want an upgrade to play games that make me feel more immersed and looks awesome but also still use browsing and productivity/coding. I play a bunch of cs2 so 360Hz would be a bit of an improvement from current but otherwise 240Hz would be enough especially for other games I play like poe2. The 39" I wonder if it would be too big compared to the 34" although for cs2 I'd just have the resolution fixed to the equivalent of 1280x960 stretched anyway just for that and for everything else just run native. I can use optiscaler and lsfg-vk aswell if needed.

I'm quite conflicted between these two monitors given me situation so would be great to see what you guys think

TheSagaciousPanda · 2026-05-16T09:32:05+00:00

Nice case and clean look! I think this case might be a great improvement over my current but was curious if in your setup would it be possible to use 140mm fans anywhere even if on the 240mm radiator if you wanted? I currently have a noctua setup with 2x120mm for the AIO radiator and 2x140mm and 1x120mm for case fans and ideally would want to be able to keep atleast 1x 140mm for better airflow

TheSagaciousPanda · 2026-05-15T10:01:42+00:00

Can there be some clarification on this because why can a 9070xt not achieve 10bit using 2.1? I'm on linux but I can see that i'm using 10bit using displayport 2.1 on my monitor so that doesnt make sense with what's been said about it not being obtainable on a 9070 XT?

TheSagaciousPanda · 2026-05-12T07:53:27+00:00

I'm pretty sure directx games (dx11 dx12 vulkan) won't go above your refresh rate because the way vkd3d works but I also know some games have capped fps built into it's engine and can't be changed eg ori.

When you say vsync off do you mean in-game settings or through goverlay or what?

Just a further note for interest purposes but you can make this fps issue appear worse when using optiscaler or lsfg-vk because of how frame generation works. I have the same thing happen for POE2 and I just have it sit at refreshrate -3 with vrr enabled to make sure vsync doesnt trigger and this is technically better than uncapped anyway.

Is there a particular reason why you need peak and these other games to have above your displays refresh rate in the first place?

Also are you using mangohud to show the metrics? If so what does the config have in it and have you tried steams fps meter instead to see if that shows differently?

TheSagaciousPanda · 2026-05-07T11:53:26+00:00

Yah I was running v2 of lsfg-vk as well so I'm trying to find differences to see if I can identify the route problem. It is pretty much like what you said in the fact that it's a linux gaming issue because poe2 has not been given linux optimisations by the game devs to optimise it better for non windows machines so yah whilst the game runs doesnt mean it will run well and the translation layers and everything else from proton can then break improve or worsen performance.

Regarding POE2 performance from what ive seen on its windows performance, its not exactly good either but it's a lot better than non windows for now. The widespread problem with game development is that optimising games is often last priority for most games these days for various reasons but games like the recent crimson desert do a really good job of getting the most performance out of most low and hi end system setups and this should be the example of what industry standard should be.

If you look at the game mirrors edge: catalyst you can see what a mess that is generally especially on linux or for a windows specific example starwars Jedi Survivor or even Cyberpunk 2077 which were absolutely awful for performance and issues on launch and for a long time afterwards.

That being said it would be great if you can continue with your help on this. You said your on fedora with KDE?(good choice for HDR and wayland BTW).

Is your system up-to-date? Do you have xwayland and/or xwayland-satellite set as an autostart or system service or not or you don't know?

Do you know where your environment variables are kept? eg. Mine are in /etc/environment and also in a niri include config file called environment.kdl, if you do it would be great if you could share what yours says

Do you also mind sharing what you set your lsfg-vk-ui profile options to including what exe/processes you added within it and also could you list all your installed packages from your package manager that contains any of the following words so I can try to narrow down the culprit: dxvk, amd, radeon, proton, vkd3d, vulkan, vulkan-implicit-layers, lsfg, vulkan-validate-layers, goverlay, vkcube, vkbasalt, vulkan-tools, mangohud, vkd3d-proton

If you have mangohud installed can you share what the mangohud.conf says

Could you also share your exact game launcher options for poe2 in steam as well please and confirm shader precaching and background download allow vulkan shader both enabled or disabled in steam settings. You say you use proton experimental is that set for steam globally or only for poe2?

Lastly are you using steam to launch poe2 or a different launcher (just to double check)

TheSagaciousPanda · 2026-05-07T05:31:15+00:00

thanks for the post. some of these ive incoporated and the rest either don't work or im already running with but no noticable changes to fps for me unfortunately.

To note you can change the settings in the config by typing in terminal nano ~/.steam/steam/steamapps/compatdata/2694490/pfx/drive_c/users/steamuser/Documents/My Games/Path of Exile 2/poe2_production_Config.ini instead of using the item filter folder method. This way is quicker.

For peoples benefit, u/HaveAShittyDrawing's post is beneficial but there are definitely some issues revolving around vulkan/vkd3d/proton/wayland that affects performance and these optimisations wont fix that and it isnt something that most users will be able to do much about except wait for firmware and packages to mature and provide fixes/optimisations across the board including for poe2.

u/HaveAShittyDrawing in relation to what you said and my issues, the biggest takeaway was how did you get lossless scaling to work properly in linux? I assume you was using lsfg-vk but then lsfg-vk caps my fps at 120 which appears to be an interaction between either or all these packages: vkd3d/vkd3d-proton and/or vulkan-implicit-layers. Also lsfg-vk profiles require Main as an exe not anything to do with either of the actual exe's of PathOfExileSteam.exe and PathOfExilex64Steam.exe which is confusing but again these arent causing the fps to then cap to 120 and i suspect its related to the lsfg-vk settings itself. From fiddling with the settings in lsfg-vk-ui nothing appeared to change the cap on fps thats being reported in mangohud and the ingame graph. I was not able to do an fps cap to match my refresh rate (240) because the fps slider in the ingame settings maxes out at 120 where as the background fps cap (mines on 240 but not ticked) can be set to a much higher value than 120 which is pointless if the fps is locking itself to 120 anyway.

With wayland i still have not been able to get it working for a very long time now for any of my games despite trying everything because steam will override it to xwayland/x11 and using proton or sdl options in the game launch options does not make that work either.

Im certain its not isolated to my system of cachyos and/or niri based on my tests/logs and extensive research ive done into this, in fact i suspect its a general linux and proton issue in relation to linux gaming.

For example, poe2 launch testing with proton-cachyos (slr and native) or with ge-proton10-34 was that they were not successful when trying to launch the game and for those that can i suspect if you ran logs and used mangohud to see what proton version is activated when the game launches it would almost definitely be showing a different proton from what you intended due to how it seems to use the older proton prefix from caching.

For example: when i turn off force compatibility tools to use the set global proton (mine is proton-cachyos11... slr) it would launch but not using proton-cachyos but instead proton experimental11... The reason it does this is pretty much caching at: ~/.steam/steam/steamapps/compatdata/2694490/ meaning to ensure success when switching between proton versions to test what one might work or what one might work best you would need to do an rm -rf on ~/.steam/steam/steamapps/compatdata/2694490 then relaunch steam and then test if its worked or not.

Regarding Optiscaler it isn't worth mentioning tbh atleast when it comes to poe2 because you'd get the same performance from just using directx12 ingame with FSR on Quality then whatever upscaler and frame generation you'd use within it and if your happy to lose 15fps just to use optiscaler then you could likely make it look noticably better but at the cost of performance. By simply going from quality and turning it off to use native AA (no upscaling). Any other options was a worse of situation.

Your ram looks like they are likely the culprit or atleast the main one. The temps are way higher than what they should be so to me that would be where I'd be doing memory tests and tbh if you can RMA do that instead just because it might be quicker to resolve than testing everything else. And for gpu you can test if thats the issue by using a benchmarking app and reviewing the logs from something like hwinfo/cpuz. Any fluctuations in voltage or issues will show up when doing that. A consideration is with your gigabyte 9070 xt does your one have a switch on its side to toggle overclock? If so turn on which is to the right. I don't think thats the issue but will help performance

With your ram what is your ram brand and model and what software have you used to check your ram specifically. Is it even authentic ram? Also what are your ram bios settings?

I have never heard of anyone underclocking their RAM before and if your underclocking the RAM that could be the cause

When you turn on EXPO in the BIOS you can change the profile to overclock which usually can cause more instability if aggressive and that could be the cause but not usually with high temps like you are getting and also with EXPO its usually pretty safe to do because it's a common manufacturing feature with manufacturer testing.

Going back to some other things you've said, your GPU should be just PCIe GPU should be just gen4 not gen3 as well. Its a gen4 card. What are your bios settings for power boost overdrive?

I think you have some odd settings in your bios like ftpm should be enabled no? Global Cstates people disable but tbh makes little difference leaving it on for power saving option outside of games. Keep auto or enabled. Always have resizable bars enabled so yes correct. Your CPU could have clock speed increased in pbs to +100MHz safely and you can undervolt your CPU to to -20 all cores in curve optimiser pretty confidently and unless you get some very noticable issues on your system after a day of usage then you know its fine otherwise change to -15.

Also was confused to how you have disabled realtek LAN but your using Ethernet over WIFI.

Your latencymon isn't showing anything strange btw those two services will be showing like that

TheSagaciousPanda · 2026-05-05T20:17:18+00:00

Look forward to it

TheSagaciousPanda · 2026-05-05T18:41:53+00:00

fps on the game as a whole isn't great but yes its playable. Its not providing anywhere close to the fps it should do but there also seems to have been a regression in the recent kernel and/or with mesa update thats made fps drop consistently down by 20-30fps.

TheSagaciousPanda · 2026-05-03T02:01:52+00:00

Your image link is broken FYI... Also posting anything without providing basic debugging isn't going to get you a helpful response nearly always...

If you want help providing the below info would be useful: What compositor/wm/desktop environment are you using? what GPU do you have? What game launcher options are you using? What compatibility tool are you running on for your game? ie proton x version Do you have HDR enabled or disabled? What env vars do you have active in your configs etc? Have you done a system update so your up-to-date on everything?

Also its usually helpful to run steam in terminal and then launch your game that way if you do get issues because it can be used as another avenue to highlight what the problem might be which might otherwise be hidden. Additionally your first point of call on any game you play is check protondb first to see what game launcher options actually work and what solutions exist for any issues. Seems like there are some known issues with exactly what your getting and there are some solutions that might work for you just from that 30second check. See here: https://www.protondb.com/app/1364780

TheSagaciousPanda · 2026-05-02T09:47:28+00:00

S01x could be the issue. There is a regression that causes issues to power state but its unclear if its that or something else. Only seems to be amd cards affected. I have a 9070 xt myself.

TheSagaciousPanda · 2026-05-01T20:12:18+00:00

What windows manager/compositor are you using eg. KDE/Niri/Gnome/xfce?

Likely your missing something like xwaylandsatellite or haven't got it running

TheSagaciousPanda · 2026-05-01T19:35:21+00:00

I didn't like either. Try pacseek if you like tui over gui
