I’m a primarily WFH architect currently running a dual setup: an LG 39GX90SA alongside an LG C3 42” 4K TV. I use the C3 for gaming and extra real estate, but jumping between the two for productivity is jarring. The 3440x1440 resolution on my current 39" just isn't enough when I need to juggle heavy architectural workflows; like comparing plan sets and submittals in Bluebeam on one half, while running Revit, AutoCAD, SketchUp, Lumion, or the Adobe suite on the other. While having dual screens gives me the raw space I need, the mismatched sizes and inconsistent PPI make the experience clunky. Constantly swiveling between the two is taking a toll on my neck and eyes. I’m looking for a single-panel solution, and the 39" form factor is the perfect sweet spot for scanning without strain. A unified, high-resolution canvas would let me seamlessly manage the multiple windows required for coordinating with clients, contractors, and engineers. Moving back to a single-screen setup would also clear up my physical desk space for the drawings, material samples, and tools that end up getting in the way otherwise. Beyond the ergonomics, I am really excited about the brightness upgrades on this new panel. It looks like it matches the punchiness of my C3 but in a true monitor format, meaning no remote and less aggressive ABL! It’s exactly the bridge I need between my current two displays! On the gaming side, my RTX 5090 is itching to push more pixels than it's currently handling, which would just be the cherry on top. I’d love the chance to put this monitor through its paces. Even if I’m not selected, I’ll be glued to the reviews as this genuinely looks like it could be my end-game display. Good luck with the launch, and thanks for the opportunity!

You don't need an Oled but at the same price on Amazon there was the **LG 39GX90SA-W** 3440x1440 240hz oled. I had to jump all the way up from my Innocn 40c1r to the LG 45" 5k2k to ensure a noticeable upgrade. I turn that Innocn vertical now as my 2nd monitor. A 40" Ultrawide is a killer vertical 2nd monitor, so I recommend that if you decide to upgrade again before this one gives out.

For me, the 800r on my 39GX90SA-W is great for gaming and my data entry job. I couldn't go back to a 15-1800r. My secondary monitor is a Neo g7 32" with 1000r curve and for my personal use I think that would be a perfect curve for my 39".

I've got an LG 39" 3440x1440 monitor now. I've been contemplating getting that around black Friday when there are sales at my local microcenter

I got mine Friday to replace my 39" 3440x1440 Ultragear and I have zero regrets. It's incredible and makes for the best gaming experience I've had hands down.

At this resolution you can't really go wrong with either monitor. I prefer the additional size so I'll be sticking with my 45", especially because the price on the 39" is probably going to be unreasonable for quite a while. I had the 39" 3440x1440 UltraGear before going to the 45" and the extra vertical space is nice. It removes the sort of squished feeling that can come with some ultrawide monitors.

I've only been looking into WOLEDs but found that they also covered planned QDs at around 16 minutes in [https://www.youtube.com/watch?v=EjCQzKwgBow](https://www.youtube.com/watch?v=EjCQzKwgBow) They have a less aggressive curve at 1800R Currently have an 1800R VA panel myself and it's great for media, productivity and gaming. I just haven't seen any mentioned in the 39" size for your height preference. LG does have a 39" currently but its 3440 x 1440. Similar to running 1440p monitor on 32" screen. Not sure if PPI is a dealbreaker as well. Here's the WOLED roadmap for comparison, has past and present models at about 19:40 [https://www.youtube.com/watch?v=eyYRevThUUw&t=1061s](https://www.youtube.com/watch?v=eyYRevThUUw&t=1061s) As for more curve talk, I'm still hesitant about the 800R curve from looking at pictures from above, but most people say it's great for 39" and higher models and you get used to it for gaming. My initial ideal monitor was WOLED 34" but with a less aggressive curve, but that's not in LGs roadmap for the next 2 years so I'm just going to give 800R a try. Saw one in person at a BestBuy with a game demo running. I thought it was fine for gaming, but don't know how it'll feel for movies or productivity, so my plan is keep my VA for productivity and WOLED for gaming. So that's the current market for 21:9 ultrawides 34" QD OLEDs at 3440x1440 now in 240hz (109 ppi) 39" LG WOLEDs at 3440x1440 now in 240hz (95 ppi) 39" LG WOLEDs at 5120x2160 late this year (142 ppi) I also haven't kept up as much with OLEDs so theres a chance a 39" QD may have been announced at CES

Yeah 39" ultrawide 240hz OLED GSYNC, I'm in love with it

I have the 39" 1440p LG OLED. PPI at that size isn't phenomenal but looks fine in games. The 5k2k looks amazing but I'm not looking to take the performance hit. I can max every game I've tried at 3440x1440 and still generally break 100 fps. I came from a Samsung Odyssey g9 49". It was incredible for productivity but kind of overkill for gaming and I wanted an OLED with more vertical space.
