I think the title here is incorrect. These are supposed to be proper RGB OLED now, not WRGB.
Shadow647@reddit
Previous gen (32GS95) was RGWB which is pretty OK with ClearType etc
Artoriuz@reddit
Do you have any source for this?

> The 32GX870B-B uses LG’s fourth-generation Primary RGB Tandem OLED panel.
From the article
Few_Permission_3756@reddit
The 32" would be the perfect monitor for me if it'd sport a KVM. Bummer.
tiradium@reddit
UCDM3 from Asus checks all the boxesbfor me
Few_Permission_3756@reddit
Oh damn, thank you for that suggestion! Do you know if a 4th gen panel is used?
tiradium@reddit
What's wrong with that?
Few_Permission_3756@reddit
I'm in a brightly lit room with a window behind me. I read several times that this setup is the worst one for QD-OLED.
tiradium@reddit
There is a black shield tech that not only helped with purple hue but also helps with light absorption. I honestly would recommend getting one and trying if you have the ability to easily return
Few_Permission_3756@reddit
Oh neat, didn't know about that tech! I'll look into it, thank you! 😄
ycnz@reddit
Anyone know what the subpixel layout will be?
Dphotog790@reddit
will not be RGBPixel if thats where your getting at only the 27inch one has that.
Seanspeed@reddit
These are RGB as far as I understand.
Dphotog790@reddit
their asking if its going to have the new True RGB stripe subpixel which these monitors are not. only the 27inch has the True RGB Stripe Subpixel. the 32inch uses WRGB / hybrid (not stripe) it has Improved tex clarity, but not perfect like the True RGB Stripe.
Seanspeed@reddit
Do you have a source for this?
It's a bit hard to get solid info on this. But I thought the whole point of 'Tandem RGB' was that it was the introduction of proper RGB to these larger OLED displays finally.
Dphotog790@reddit
RGB Tandem OLED refers to the stacked structure of the light-emitting layers, which multiplies brightness and durability. In contrast, true RGB Vstripe refers to the physical subpixel layout

IgnorantGenius@reddit
Why don't they make 35/36" 4K monitors?
Seanspeed@reddit
32" is already considered quite a massive display by most PC user standards.
Just a small market.
IsometricRain@reddit
There's a 37" samsung, but it's IPS.
Also a 38" asus pg38uq, but the pricing is a bit silly.
It'd be cool to have 35/36 options, but the market isn't big enough. 32 is great for most desks, and anyone wanting a significantly bigger screen has plenty of 42 inch options (at only a slight upcharge) or these new >40 inch ultrawides.
The 37 inch samsung is a decent budget-ish compromise for people who don't want to go to a 42 but need the extra size. Not a gaming monitor though.
IgnorantGenius@reddit
That 38" asus pg38uq is almost what I have now, which is a 43" xg438 4k120 with 600nits peak brightness but it's a va panel and has black smearing issues.
The 37 Inch Odyssey G7 G75F looks nice at a glance, but at $600, I would rather just get a 4K 240hz oled.

saboglitched@reddit
2560*1080p on a 44.5" screen is 62 PPI, that's honestly terrible. Why even make a dual mode?
fkenthrowaway@reddit
I assume the image is not across the whole screen.
saboglitched@reddit
Even if the image isn't the whole monitor size is that resolution. This will look like watching 480p video again
Seanspeed@reddit
No, it'll look like a slightly worse 1080p image on a 32" screen.
Also, monitors usually aren't cemented into place. You can push them back a bit if you want to make it 'smaller'.
saboglitched@reddit
And a 1080p image looks very bad on a 32" screen to begin with lol. By being farther away it appears less blurry but you lose FOV. By that logic lets just use 10" screens.
Seanspeed@reddit
Can that 10" monitor also blow up to be 32" and double the resolution?
How are y'all not understanding the point here? Of course it's not an absolutely perfect solution, but if you REALLY want that ultra high refresh rate for certain applications, it's still a useful feature.
Sh1rvallah@reddit
And this is even worse than that. The 45" is roughly the height of a 36" monitor with extra width. The 32" equivalents are the 39" ultrawides.
Sh1rvallah@reddit
36" not 32".
Sh1rvallah@reddit
It is, that's the whole point of dual mode
bizude@reddit
E-sports players want it
saboglitched@reddit
Real esport players don't game on 44.5 in monitors, not even close.
bizude@reddit
No true scotsman, eh?
saboglitched@reddit
Have you seen the monitors pro esports players play on?
IsometricRain@reddit
He didn't say "pro".
Lots of casual esports players using all sorts of screen sizes: living room TVs, 13 inch laptops, and whatever else they have lying around.
I don't mind esports games played at lower PPI if everything else (frame rate, low input lag, good contrast) makes up for it. It makes sense to offer it as a value-add even if only a tenth of the buyers find a use for it. It's a cool feature, and a majority of esports (yes, "real esports) is played casually.
saboglitched@reddit
The esport players that actually would benefit from over 240hz monitors are not the casual couch gamers, the wireless input lag and wifi lag would far exceed the latency from a lower refresh rate. The context was why would people need 240hz+ refresh rate at the expense of ultra low ppi, and the main market for that (ultra competitive esport players), are not using 32 or 44 in 1080p monitors. Nothing wrong with living room tv gaming, but those people are often gaming at 60hz or less, maybe 120, and would prefer sharper visuals most likely anyways, so dual mode crippling visual quality to go beyond 165/240 hz is not justified by that.
Seanspeed@reddit
It's the same density as on the 32" screen.
Why? For people who are playing a game where they care less about IQ and more about having ultra high framerates. Same reason any of these monitors have these dual mode usages.
saboglitched@reddit
No, the 32" is 70 PPI, and that's still awful for a monitor. High refresh rate above 240 HZ (given low latency monitor) is largely placebo, but even for 0.01% esport pros that can benefit from it, use 24" or smaller size for better clarity (which would have 92 ppi on 1080p btw, and while fine for esports still doesn't look very clear).
Vb_33@reddit
Need them 4320p ultra wides.
saboglitched@reddit
Need much better connectors for that. DP2.1 only supports 8K60hz (even without ultrawide) without using color compression. Probably 10+ years away at this rate
InevitableSherbert36@reddit
So they can advertise 330 Hz.
Kyrond@reddit
Why is dual mode still needed? What's the limitation, don't we have bandwidth for 4k/480?
rubiconlexicon@reddit
I don't think it's bandwidth but rather the driving circuit required to control 3840*2160 pixels at 480Hz is not engineered yet.
Vb_33@reddit
There isn't a single 480hz 4k OLED yet. Seems like we're capping out at 240hz for now but progress is blistering fast so who knows what we'll have next year.
russia_delenda_est@reddit
Yeah i can get lg g5 which would 2x brighter and also 165hz thanks
bizude@reddit
Seems odd that one display supports UHBR20, while the other one only supports 13.5. Bandwidth requirements should be similar for both screens, given the resolution and refresh rate differences.
Dphotog790@reddit
cause like all things money. If they can cut corners they will which they are by going UHBR 13.5
Kentarchos@reddit
The 45 inch looks to be a very limited refresh of the 2025 model, so I think that LG must not have made any change to the processing, leaving it with the same bandwidth as the previous version.
Vb_33@reddit
The reason is cost.
Flanathefritel@reddit
a shame for the coating .
Exortric@reddit
Ich kann einfach nicht glauben dass LG hier immernoch auf Matte Beschichtungen in der Gaming Sektion setzt. Die verschließen doch echt die Augen.
Heavy-Marionberry892@reddit
4k should have RGB stripe but there is some confusion in specs
jenesuispasbavard@reddit
How is the 45GX950B different from the A that came out last year? Specs look exactly the same.
dreiter@reddit
Sh1rvallah@reddit
Oh, so it's a downgrade
RTX5090_Lover@reddit
Meh, these look OK. LG is always overpriced with their OLED monitors. I've gotten better ones from ASUS.
Dphotog790@reddit
im waiting for Asus to adapt this panel for theirs and theyll have a few more things im sure but of course will come at asus premium but i think thats what most people end up doing anyways buying asus.
eqyliq@reddit
Weren't we supposed to get a 34" unit too in the 5k2k LG realm? A 27" 4K equivalent
I-never-joke@reddit
This is all I want, a display that sits next to my 4k 27'' nicely is ideal, preferably 240hz and I'm sold.
peruka@reddit
5k2k is bullshit marketing. This is 4k ultrawide
Vb_33@reddit
Yeah but it's easier for normies to understand
Plank_With_A_Nail_In@reddit
2k, 4k, 5k none of these are part of the official way to describe screen sizes.
5120×2160 is WUHD
gahlo@reddit
"4k ultrawide" is unclear because that could eother be referring to and ultrawide 2160p monitor or the 3840x1600 ultrawides that are "4k" wide.
The bullshit marketing was letting "4K" be a thing in the first place.
WhoTheHeckKnowsWhy@reddit
Grey uniformity tends to be harder with size, here's hoping LG has made some improvements on that QA front.
Tandem is one of those techs i want to jump into but will need to see how the 32FX870-B turns out. It's its good, then the odds of Asus and Gigabytes using that panels being good jumps immensely.
lutel@reddit
Oh my i have 27'' and I think this is sweet spot, but 31 is very tempting as now it preserved very crisp text. If KVM will be good, I may consider to switch to it.
